Prevalence of Sleep Disturbance Potential-Associated Factors among Undergraduate Pharmacy Students in Saudi Arabia.

Background: Many studies across the globe have observed the significant effect of sleep disturbance on the academic achievement of medical students. Objective: This research was conducted to define the prevalence of sleep disturbance and to discover the consequences and management of this condition among undergraduate pharmacy students of Mohammed Al-Mana College for Medical Sciences (MACHS). Methods: We conducted a questionnaire-based online survey among different levels of MACHS pharmacy students. Results: A total of 165 students participated in the study, of whom 132 (80%) were females and 33 (20%) were males. Most of the participants, 142 (86.06%), were staying with their parents, whereas few of them were staying alone (23; 13.94%). While a handful of them, 29 (17.58%), did not have their bedrooms, most of them had their bedrooms (136; 82.42%). When asked about drinking caffeine-rich products in the afternoon or at night, most of them responded "sometimes" (78; 47.27%), followed by the category "always" (61; 36.97%), "rarely" (15; 9.09%), and then the category of students who responded "not at all" (11; 6.67%). Overall, 35 (21.21%) of the study participants had a smoking habit, 72 (43.63%) tried to treat their sleep disturbance, whereas 42 (25.45%) were getting treatment for insomnia. Conclusion: Most pharmacy students at MACH College, especially females, have sleep problems. Mostly, the prevalence is common during exam periods, and it mildly affects their grade point average.

Long-Term Neurodevelopmental Outcome of Children With Mild Traumatic Brain Injury.

BACKGROUND: To investigate the long-term outcome of pediatric mild traumatic brain injury (mTBI) in terms of neurocognitive, behavioral, and school functioning and to identify clinical risk factors for adverse outcomes. METHODS: This study describes the follow-up of a prospective multicenter sample of 89 children with mTBI 3.6 years postinjury and 89 neurologically healthy children matched for sex, age, and socioeconomic status. Neurodevelopmental outcomes were assessed using an intelligence test, behavioral questionnaires, computerized neurocognitive tests, and longitudinal (pre- and postinjury) standardized school performance data. RESULTS: Children with mTBI exhibited intelligence in the average range but had more behavioral problems related to inattentiveness (P = 0.004, d = 0.47) and hyperactive impulsivity (P = 0.01, d = 0.40) and showed poorer neurocognitive performance in information processing stability (P = 0.003, d = -0.55) and Visual Working Memory (P = 0.04, d = -0.39) compared with matched peers. Longitudinal school performance data revealed poorer performance in Technical Reading up to two years postinjury (P = 0.005, d = -0.42) when compared with normative data. Clinical risk factors did not reveal predictive value for adverse outcomes in children with mTBI. CONCLUSIONS: This study indicates that children with mTBI are at risk of long-term deficits in neurocognitive and behavioral functioning, with longitudinal evidence suggesting shortfalls in school performance up to two years postinjury. Clinical risk factors do not provide a solid basis for long-term neurodevelopmental prognosis. Findings emphasize the importance of, and challenges for, early identification of children at risk for adverse neurodevelopmental outcome after mTBI.

Finding significant indicators of PharmD academic performance to impact future students.

OBJECTIVE: The purpose of this study is to identify which factors, both objective and subjective, from a student pharmacist's background are significantly related to academic performance in the professional PharmD program. METHODS: Texas student pharmacists in their first three professional years during the 2022-2023 academic year were invited to participate in a 41-item survey to gather data on their undergraduate background, work experience, grit, and academic resilience. The survey responses were paired with the student pharmacist's cumulative grade point average (GPA) to assess the relationships between the variables and academic performance using Mann-Whitney U tests, Kruskal-Wallis tests, and Spearman's correlations. RESULTS: Two hundred and fifty-one student pharmacists currently enrolled in a PharmD program in Texas responded to the survey invitation. Spearman's rho correlations showed weak positive and significant relationships between GPA and Grit scores as well as GPA and Resilience scores. Additionally, there is a moderate positive and significant relationship between student pharmacists' Grit and Resilience scores. CONCLUSION: The results suggest that assessing for Grit or Resilience as part of the admission process could aid in identifying future student pharmacists who would experience pharmacy school academic success. Integrating tools that develop Grit and Resilience in the PharmD curriculum could improve student pharmacists' academic performance.

School environmental factors, pupils' characteristics, and academic performance: The case of junior high school pupils of the Krachi west district of Ghana.

Background: Data suggest that Ghana has made significant improvements in the educational system, resulting in some accomplishments. Nonetheless, pupils' academic performance at the junior high school level and in the Basic Education Certificate Examination (BECE) remains poor nationally. Some factors have been identified to influence poor academic performance in some parts of Ghana, but none in the Krachi West district. Thus, it has become imperative to determine the local factors accountable for this trend and identify the most appropriate localised solutions. Materials and methods: An embedded research design was employed to ascertain the influence of pupils' characteristics and school environment factors on academic performance. In all, 361 participants (325 BECE candidates, 12 teachers, 12 head teachers and 12 PTA/SMC Chairpersons) were selected using cluster sampling, simple random and purposive sampling across 12 schools in the district. The academic performance of pupils was assessed using scores from six (6) subjects in the standardised district-level mock examination. Results: Based on the examination scores, half of the pupils performed poorly in the six subjects. Even though from the quantitative study, pupils' characteristics had no significant influence on academic performance, school location (ß = -3.29, p < 0.01), school type (ß = 1.15, p < 0.01), and school environmental factors (ß = 0.807, p = 0.024) were significant predictors of academic performance in the district. Pupils in private schools were thrice more likely to achieve average academic performance than pupils from public schools (OR = 3.2, CI = 1.06-9.47). Also, schools with good environmental factors were twice as likely to have average academic performance than schools with poor environmental factors (OR = 2.2 CI = 1.11-4.52). Conclusion: While school environment factors and pupil characteristics have a relationship with academic performance as suggested by the ecological theory, it was established in this study that only school location, school type and school environment factors were the significant predictors of academic performance in the Krachi West District. Therefore, education stakeholders need to consider these predictors when coming up with integrated but local strategies to improve pupils' academic performance in that district.

Cross-sectional association between frequency of vigorous physical activity and academic achievement in 214,808 adolescents.

Background: This study explores the intricate link between vigorous physical activity and academic achievement in adolescents. By analyzing data from the Health Behaviour in School-aged Children (HBSC) survey, it seeks to understand how engaging in high-intensity physical activities influences academic achievement. Methods: A comprehensive cross-sectional analysis was conducted on a vast dataset comprising 214,808 adolescents aged 11, 13, and 15 years. The frequency of vigorous physical activity was determined through self-reports, while academic achievement was assessed based on students' self-perceptions, reflecting their understanding of teachers' evaluations of their academic performance. Results: Adolescents who reported engaging in vigorous physical activity daily were more likely to report higher academic achievement. This positive correlation was consistent across various demographic groups, including different age cohorts and both genders, indicating a universal benefit of regular vigorous physical activity on perceived academic success. Conclusion: The findings of this study underscore the significant role that regular vigorous physical activity plays in the academic lives of adolescents. The correlation between daily vigorous physical activity and enhanced self-reported academic achievement suggests that encouraging high-intensity physical activities in schools could be a key strategy in boosting educational outcomes.

Sleep Disorders' Prevalence and Impact on Academic Performance among Undergraduate Nursing Students in a Selected University, United Arab Emirates.

Introduction: Throughout their academic pursuits, students may encounter various sleep-related issues, including insomnia, sleep apnea, hypersomnia, or sleep terror disorder. These disorders can profoundly impact their well-being, emotional state, and academic achievements. Objective: This study, of significant relevance to the field of nursing and sleep disorders, aimed to investigate the prevalence of sleep disorders and their impact on academic performance among undergraduate nursing students in the United Arab Emirates. Methods: A cross-sectional research method was implemented among 177 undergraduate nursing students. Two tools were used: Too I consisted of two parts: sociodemographic and academic performance classifications, whereas Tool II comprised the SLEEP-50 questionnaire. Results: Our findings revealed that 30.6% of nursing students had one or more sleep disorders. Insomnia was the most prevalent among the nursing students (37.5%), followed by circadian rhythm (33.3%), narcolepsy (26.6%), sleep apnea and restless leg syndrome (25%), nightmares (22.2%), and sleepwalking (11.11%). There was a significant relation between restless leg syndrome and academic performance, while in linear regression analysis, it was found that the variable that most affects sleep is gender. Conclusion: The implications of this study's findings are clear-nursing schools must intensify their efforts to raise awareness about the detrimental effects of sleep problems on academic performance. Furthermore, subsequent research is crucial to evaluate the execution of interventions aimed at preventing such disorders.

Performance of ChatGPT in Solving Questions From the Progress Test (Brazilian National Medical Exam): A Potential Artificial Intelligence Tool in Medical Practice.

Background The use of artificial intelligence (AI) is not a recent phenomenon, but the latest advancements in this technology are making a significant impact across various fields of human knowledge. In medicine, this trend is no different, although it has developed at a slower pace. ChatGPT is an example of an AI-based algorithm capable of answering questions, interpreting phrases, and synthesizing complex information, potentially aiding and even replacing humans in various areas of social interest. Some studies have compared its performance in solving medical knowledge exams with medical students and professionals to verify AI accuracy. This study aimed to measure the performance of ChatGPT in answering questions from the Progress Test from 2021 to 2023. Methodology An observational study was conducted in which questions from the 2021 Progress Test and the regional tests (Southern Institutional Pedagogical Support Center II) of 2022 and 2023 were presented to ChatGPT 3.5. The results obtained were compared with the scores of first- to sixth-year medical students from over 120 Brazilian universities. All questions were presented sequentially, without any modification to their structure. After each question was presented, the platform's history was cleared, and the site was restarted. Results The platform achieved an average accuracy rate in 2021, 2022, and 2023 of 69.7%, 68.3%, and 67.2%, respectively, surpassing students from all medical years in the three tests evaluated, reinforcing findings in the current literature. The subject with the best score for the AI was Public Health, with a mean grade of 77.8%. Conclusions ChatGPT demonstrated the ability to answer medical questions with higher accuracy than humans, including students from the last year of medical school.

Impact of a change from A-F grading to honors/pass/fail grading on academic performance at Yonsei University College of Medicine in Korea: a cross-sectional serial mediation analysis.

PURPOSE: This study aimed to explore how the grading system affected medical students' academic performance based on their perceptions of the learning environment and intrinsic motivation in the context of changing from norm-referenced A-F grading to criterion-referenced honors/pass/fail grading. METHODS: The study involved 238 second-year medical students from 2014 (n=127, A-F grading) and 2015 (n=111, honors/pass/fail grading) at Yonsei University College of Medicine in Korea. Scores on the Dundee Ready Educational Environment Measure, the Academic Motivation Scale, and the Basic Medical Science Examination were used to measure overall learning environment perceptions, intrinsic motivation, and academic performance, respectively. Serial mediation analysis was conducted to examine the pathways between the grading system and academic performance, focusing on the mediating roles of student perceptions and intrinsic motivation. RESULTS: The honors/pass/fail grading class students reported more positive perceptions of the learning environment, higher intrinsic motivation, and better academic performance than the A-F grading class students. Mediation analysis demonstrated a serial mediation effect between the grading system and academic performance through learning environment perceptions and intrinsic motivation. Student perceptions and intrinsic motivation did not independently mediate the relationship between the grading system and performance. CONCLUSION: Reducing the number of grades and eliminating rank-based grading might have created an affirming learning environment that fulfills basic psychological needs and reinforces the intrinsic motivation linked to academic performance. The cumulative effect of these 2 mediators suggests that a comprehensive approach should be used to understand student performance.

Study approaches mediate associations between learning environment and academic performance.

BACKGROUND: While study approaches have been directly associated with students' academic performance, learning environment factors may play a more indirect role. The aim of this study was (i) to assess learning environment factors as predictors of students' average exam grades, and (ii) whether study approaches mediated associations between learning environment factors and exam grades. METHODS: Three annual surveys (2017-2019) yielded data from a total of 263 Norwegian occupational therapy students. Learning environment factors were assessed with the Course Experience Questionnaire, and the Approaches and Study Skills Inventory for Students were used to assess study approaches. Linear regression analyses and mediation analyses were performed. RESULTS: Higher levels of 'student autonomy' were directly associated with lower averaged grades whereas higher levels of 'appropriate workload' were associated with higher averaged grades. There were statistically significant total indirect effects of 'clear goals' and 'appropriate workload' on grades; these effects occurred through the study approach variables. However, all learning environment variables showed one or more relationships with academic performance that was mediated by study approach variables. CONCLUSION: Learning environment variables appear to be complexly associated with academic performance, both directly and indirectly.

Assessing the predictive validity of expectancy theory for academic performance.

BACKGROUND: Despite expectancy theory's widespread appeal and influence as a framework for motivation in organizational and educational settings, studies that have examined the theory's validity for performance-based outcomes, particularly with academic performance as the criterion, have been characterized by inconsistent results. Given numerous methodological concerns associated with past studies (e.g., prevalence of between-person rather than within-person design), we examined the predictive validity of expectancy theory for academic performance using methods that were consistent with the theory's original conceptualization. Additionally, we assessed the validity of the theory for students' study effort. METHODS: The final sample included 123 undergraduate students who reported their final grades in four courses. Study effort and other variables were measured with self-report surveys. Because course grades were nested within each person, multilevel modeling was used to test study hypotheses. RESULTS: Both the valence model and the force model predicted a student's current study effort, but contrary to expectations, neither model predicted a student's final course grades. In contrast, both valence for academic success and the simplified force model (based only on valence and expectancy) predicted current study effort, final course grades, and explained incremental variance beyond cognitive ability. Furthermore, the predictive validity of this force model was relatively stable across the 11 weeks of the study. CONCLUSIONS: Based on methods congruent with expectancy theory's original framework, we find that the force model does not predict academic performance. An alternative version of the model, however, predicts course grades and has incremental validity over cognitive ability. Our results have several significant theoretical and practical implications.

A predictive model for classifying college students' academic performance based on visual-spatial skills.

As the application of visual-spatial skills in academic disciplines, vocational fields and daily life is becoming more and more prominent, it is of great theoretical and practical significance how to make use of big data and artificial intelligence technology to conduct research on the relationship between visual-spatial skills and students' grades. This paper explores and analyses from the perspective of artificial intelligence, combining students' visual-spatial skills and students' specific attribute characteristics to construct an expert system, which defines the prediction of academic performance as a classification problem corresponding to the five categories of excellent, good, moderate, passing, and weak, respectively, and based on which a deep neural network-based classification prediction model for students' performance is designed. The experimental results show that visual-spatial skills plays an important role in the professional learning of science and engineering students, while the classification model designed in this paper has high accuracy in the grade prediction process. This paper not only helps to fill the gaps in the current research field, but is also expected to provide scientific basis for educational practice and promote the development of the education field in a more intelligent and personalized direction.

Education infrastructure inequality and academic performance in Ghana.

The main thrust of this study was to assess the infrastructure inequality and academic performance nexus. Education statistics (2018) from the Ghana Statistical Service was used for the study. Firstly, ANOVA was used to estimate whether district-level academic performance differed at various infrastructure distribution levels (Infrastructure Quintile levels). The study further assessed the relationship between infrastructure and academic performance based on the System General Methods of Moments technique. It was found that the difference in district-level academic performance is conditioned on the infrastructure inequality. Also, previous academic performance had a significant positive relationship with performance. A U-shaped relationship found to exist between academic performance and class size, The study recommends the pursuit of policies aimed at bridging the education infrastructure gap such as prioritisation of education infrastructure development in deprived communities, so as, to impact academic performance.

The Flipped Classroom Approach: A Review of Cognitive Styles and Academic Performances.

There has been a surge in the efforts to efficiently improve students' academic performance recently such that their depth of learning as well as their academic attainment is elevated. The identification of the needs and requirements of students is imperative for this to materialize. The classroom setting differs around the globe, with several factors affecting how teaching and learning are conducted. Versatile cognitive preferences among students also play a unique role in the way they acquire education. Active learning is a strategy that challenges the traditional teacher-centered paradigm. One such technique in active learning involves the "flipped classroom," also called "inverted classroom." The flipped classroom has been introduced as a novel educational technique in numerous areas of learning and has proven to have a more favorable influence. The concept of the flipped classroom is relatively novel in this regard. The idea and application of flipped classrooms and their effect on the academic performance of students with different cognitive styles have been studied by many researchers. Didactic lectures usually take a back seat (as supportive videos) to facilitate student learning in this format. This review aims to examine the mechanisms through which the flipped classroom approach affects the two cognitive styles: field-dependent and field-independent. The online component of the flipped classroom favors the field-independent students and helps them perform better through an in-class session as compared to the field-dependent students. The review further discusses the benefits of the flipped classroom for both field-dependent and field-independent students.

Short, frequent physical activity breaks improve working memory while preserving cerebral blood flow in adolescents during prolonged sitting - AbbaH teen, a randomized crossover trial.

PURPOSE: Physical activity (PA) breaks during school lessons have been suggested as a promising strategy to improve working memory performance in children and adolescents. There is a lack of studies investigating the underlying physiological mechanisms of PA on cognition, especially among adolescents. This study aimed to investigate the effects of different types of short frequent PA on adolescents' cognitive task-related changes in cerebral blood flow in the prefrontal cortex (PFC) and working memory performance compared to prolonged sitting. METHODS: In this randomized crossover study, adolescents visited the laboratory on three different occasions for 80-minute sessions of prolonged sitting interrupted by four breaks for three minutes of simple resistance training (SRA), step-up at a pre-determined pace (STEP), or remaining seated (SOCIAL). Before and after each session, cognitive task-related changes in cerebral blood flow (oxygenated-hemoglobin, Oxy-Hb) during working memory tasks (1-, 2-, 3-back tests) were measured using functional near-infrared spectroscopy in the PFC. Accuracy and reaction time were derived from the working memory tasks. Linear mixed-effect models were used to analyze the data. RESULTS: A total of 17 students participated (mean age 13.6 years, 11 girls). Significant time x condition interactions were noted for Oxy-Hb in the most demanding working memory task (3-back), with a decrease following prolonged sitting in the SOCIAL condition compared to both the SRA (ß 0.18, 95% CI 0.12, 0.24) and the STEP (ß 0.11, 95% CI 0.05, 0.17). This was observed in parallel with improvements in reaction time following SRA (ß -30.11, 95% CI -59.08, -1.13) and STEP (ß -34.29, 95% CI -69.22, 0.63) although this was only significant for the SRA and no improvements in the SOCIAL condition. CONCLUSION: We found that short frequent PA breaks during prolonged sitting among adolescents can prevent the decrease in cognitive task-related changes in cerebral blood flow that occur following prolonged sitting. This was observed simultaneously with improvements in working memory, indicating that changes in cerebral blood flow could be one factor explaining the effects on working memory. Future studies should investigate the efficacy of implementing these PA breaks in schools. TRIAL REGISTRATION: Retrospectively registered on 21/09/2020, ClinicalTrial (NCT04552626).

Decline in academic performance and mental health during the COVID-19 pandemic: a cross-sectional survey among Sapienza University of Rome students.

Introduction: The COVID-19 pandemic has posed significant challenges to the education system, leading to changes in student academic performance and mental health. The aim of this study was to evaluate variables relating to changes in academic performance and mental health during the pandemic. Methods: We carried out a cross-sectional study from 28 February 2022 to 13 April 2022, during the free SARS-CoV-2 screening campaign offered by Sapienza University of Rome. A structured questionnaire was constructed to explore the decline in academic performance during the COVID-19 pandemic. The Coronavirus Anxiety Scale (CAS), a validated self-reporting mental health screener of dysfunctional anxiety associated with the coronavirus crisis, was used. Results: A sample of 1,134 students was enrolled. A total of 25.4% of the participants reported a decline in academic performance. In addition, Coronavirus Anxiety Scale scores revealed that 133 (11.5%) students had a dysfunctional anxiety problem due to COVID-19. A multivariable logistic regression model showed that being a senior student (aOR: 0.70 95% CI: 0.52-0.96) and having good financial status (aOR: 0.64, 95% CI: 0.47-0.88) decrease the likelihood of a decline in academic performance, while not being Italian (aOR: 2.12, 95% CI: 1.29-3.48), having felt the need for psychological support (aOR: 2.58, 95% CI: 1.87-3.55) and being enrolled in a science/technology faculty (aOR: 1.81, 95% CI: 1.27-2.57) were more likely to result in a decline in academic performance. Conclusion: Our results show that the pandemic has affected academic performance. The COVID-19 emergency highlighted the importance of considering mental health and economic status in policymaking to effectively support students.

Deciphering dynamic interactions among multidimensional psychological motivations, academic performance, and sociocultural adjustment: The critical influence of excessive WeChat use.

As the preeminent mobile social media platform in Mainland China, WeChat's meteoric expansion has revolutionized the dynamics of interpersonal communication and the modalities of mutual interaction among individuals. Despite the escalating significance of mobile social media in the cross-cultural adaptation of international students, existing scholarly works have largely neglected the underlying relationship between psychological motivations, excessive WeChat use, academic performance, and sociocultural adaptation of these students. Anchored in uses and gratifications theory and cross-cultural adaptation paradigm, the primary objectives of this study are to devise a theoretical model and to scrutinize differential psychological motivations propelling international students' WeChat usage, its association with excessive WeChat use, and impacts on academic performance and sociocultural adjustment. The proposed model undergoes meticulous evaluation through data amassed online from 598 Chinese international students studying in Germany. Sequential analytical techniques, especially Confirmatory Factor Analysis and Structural Equation Modeling, were employed to elucidate the dynamic interplay among key variables. The final results validate the path effect suggesting that both hedonic and social motivations are positive predictors of excessive WeChat use. Moreover, excessive WeChat use is negatively correlated with academic performance and sociocultural adjustment. However, utilitarian motivation is not significantly related to excessive WeChat use. By demystifying the driving factors and consequences of excessive WeChat use, these findings not only accentuate the pivotal role of mobile social media in the cross-cultural adaptation of international students but also enrich the theoretical landscape and enhance the strategic approaches for educators and academic institutions.

Factors associated with poor sleep quality among dental students in Malaysia.

Background: Good sleep quality is crucial for dental students as they must have optimal cognitive function, memory, and decision-making to accomplish their learning requirements. This study aims to determine sleep quality, its associated factors, and the association between sleep quality and academic performance among dental students in Malaysia. Methods: This cross-sectional study involved dental students at four public universities in Malaysia. A validated Pittsburgh Sleep Quality Index (PSQI) questionnaire was used to assess their sleep quality. An additional self-administered questionnaire was employed to obtain the students' sociodemographic profile, lifestyle, and academic performance. The data were analysed using descriptive, chi-square, and multiple logistic regression. Results: Three hundred eighty-four dental students participated in this study. About half of the dental students (51.6%) have poor sleep quality. The mean of sleep hours per night was 5.72 (SD 1.06). The sleep quality was significantly poor among Malay students (P = 0.023), students who stayed at hostel (P = 0.002), and those who consumed caffeinated drinks (P = 0.028). Multiple logistic regression analysis revealed that the poor sleep quality was significantly associated with self-perceived poor academic performance (Adjusted Odds Ratio (AOR) 2.95, 95% CI [1.25-6.96], P-value = 0.013) and students skipping class (AOR 1.70, 95% CI [1.00-2.91], P-value = 0.046). Conclusions: Most of the dental students in Malaysia have poor sleep quality. Ethnicity, accommodation, and caffeine consumption were significantly associated with sleep quality. Awareness to sleep quality among dental students is needed to ensure they are able to cope with the challenging dental school learning environment.

Digital technology and mental health: Chinese university students' perspectives on the impact of social media.

Background: To address the growing concerns about mental health issues among Chinese university students, our study investigates the impact of social media on their mental health. This study intends to shed light on how these students' use of social media platforms contributes to these mental health issues, given that it has been estimated that up to 30% of university students in China suffer from mental health issues. Methods: We investigate the extent of this issue by looking at how Chinese social media platforms like WeChat, Weibo, and QQ impact students' mental health. To gain a comprehensive insight into students' perspectives, this study's sole methodology is qualitative semi-structured interviews. Our core claim asserts that social media considerably affects Chinese university students' mental health, with both positive and negative consequences. Results: The findings show how closely social media use and Chinese university students' mental health are related. These networks let people connect and get support but also encourage social comparison and stigma towards mental illness. Students use a variety of coping skills, such as self-regulation techniques, digital detoxification techniques, and looking for emotional support in online networks. These results highlight the need for a complex understanding of social media's effects on mental health. Our study also recognizes students' capacity for adaptation and resilience as they traverse the digital world, offering theoretical and practical applications for successfully juggling online and offline lives. Conclusion: In the end, our study contributes to a thorough and culturally sensitive understanding of how social media affects the mental health of Chinese university students.

Predicting performance of students by optimizing tree components of random forest using genetic algorithm.

Prediction of student academic performance is still a problem because of the limitations of the existing methods specifically low generalizability and lack of interpretability. This study suggests a new approach that deals with the current problems and provides more reliable predictions. The proposed approach combines the information gain (IG) and Laplacian score (LS) for feature selection. In this feature selection scheme, combination of IG and LS is used for ranking features and then, Sequential Forward Selection mechanism is used for determining the most relevant indicators. Also, combination of random forest algorithm with a genetic algorithm for is introduced for multi-class classification. This approach strives to attain more accuracy and reliability than current techniques. The case study shows the proposed strategy can predict performance of students with average accuracy of 93.11 % which shows a minimum improvement of 2.25 % compared to the baseline methods. The findings were further confirmed by the analysis of different evaluation metrics (Accuracy, Precision, Recall, F-Measure) to prove the efficiency of the proposed mechanism.

Cannabis Use and Academic Performance in College Students: The Role of Procrastination.

Objective: The current study investigated procrastination as a potential moderator of the association between cannabis use and college grade point average (GPA). Participants: 220 college students (ages 18 - 24; 71.8% female) in the Northwestern U.S. who were registered for classes in Fall 2021. Methods: Demographic questions, substance use history, the Beck Anxiety Inventory, the Center for Epidemiologic Studies Depression scale, and a Procrastination scale were completed via an online survey. Official term and cumulative GPA records were also collected. Results: A regression model indicated that procrastination moderated the association between lifetime cannabis use and cumulative college GPA, whereas this moderation was not present when examining the relationship between past month cannabis use and term GPA. Conclusion: The current study identifies a putatively modifiable factor that may be related to academic performance for students who use cannabis. These results may help inform future interventions designed to help students using cannabis succeed academically.
