RESUMO

BACKGROUND: Massive open online courses (MOOCs), as originally conceived, promised to provide educational access to anyone with an internet connection. However, the expansiveness of MOOC education has been found to be somewhat limited. Nonetheless, leading universities continue to offer MOOCs, including many in the health sciences, on a number of private platforms. Therefore, research on online education must include thorough understanding of the role of MOOCs. To date, studies on MOOC participants have focused mainly on learners' assessment of the course. It is known that MOOCs are not reaching the universal audiences that were predicted, and much knowledge has been gained about learners' perceptions of MOOCs. However, there is little scholarship on what learners themselves gain from participating in MOOCs. OBJECTIVE: As MOOC development persists and expands, scholars and developers should be made aware of the role of MOOCs in education by examining what these courses do offer their participants. The objective of this qualitative synthesis of a set of MOOC evaluation studies was to explore outcomes for MOOC learners, that is, how the learners themselves benefit from participating in MOOCs. METHODS: To explore MOOC learners' outcomes, we conducted a qualitative synthesis in the form of a deductive thematic analysis, aggregating findings from 17 individual studies selected from an existing systematic review of MOOC evaluation methods. We structured our inquiry using the Kirkpatrick model, considering Kirkpatrick levels 2, 3, and 4 as potential themes in our analysis. RESULTS: Our analysis identified six types of Kirkpatrick outcomes in 17 studies. Five of these outcomes (learning/general knowledge, skills, attitudes, confidence, and commitment) fit into Kirkpatrick Level 2, while Kirkpatrick Level 3 outcomes concerning behavior/application were seen in four studies. Two additional themes were identified outside of the Kirkpatrick framework: culture and identity outcomes and affective/emotional outcomes. Kirkpatrick Level 4 was not represented among the outcomes we examined. CONCLUSIONS: Our findings point to some gains from MOOCs. While we can expect MOOCs to persist, how learners benefit from the experience of participating in MOOCs remains unclear.

RESUMO

BACKGROUND: Massive open online courses (MOOCs) have the potential to make a broader educational impact because many learners undertake these courses. Despite their reach, there is a lack of knowledge about which methods are used for evaluating these courses. OBJECTIVE: The aim of this review was to identify current MOOC evaluation methods to inform future study designs. METHODS: We systematically searched the following databases for studies published from January 2008 to October 2018: (1) Scopus, (2) Education Resources Information Center, (3) IEEE (Institute of Electrical and Electronic Engineers) Xplore, (4) PubMed, (5) Web of Science, (6) British Education Index, and (7) Google Scholar search engine. Two reviewers independently screened the abstracts and titles of the studies. Published studies in the English language that evaluated MOOCs were included. The study design of the evaluations, the underlying motivation for the evaluation studies, data collection, and data analysis methods were quantitatively and qualitatively analyzed. The quality of the included studies was appraised using the Cochrane Collaboration Risk of Bias Tool for randomized controlled trials (RCTs) and the National Institutes of Health-National Heart, Lung, and Blood Institute quality assessment tool for cohort observational studies and for before-after (pre-post) studies with no control group. RESULTS: The initial search resulted in 3275 studies, and 33 eligible studies were included in this review. In total, 16 studies used a quantitative study design, 11 used a qualitative design, and 6 used a mixed methods study design. In all, 16 studies evaluated learner characteristics and behavior, and 20 studies evaluated learning outcomes and experiences. A total of 12 studies used 1 data source, 11 used 2 data sources, 7 used 3 data sources, 4 used 2 data sources, and 1 used 5 data sources. Overall, 3 studies used more than 3 data sources in their evaluation. In terms of the data analysis methods, quantitative methods were most prominent with descriptive and inferential statistics, which were the top 2 preferred methods. In all, 26 studies with a cross-sectional design had a low-quality assessment, whereas RCTs and quasi-experimental studies received a high-quality assessment. CONCLUSIONS: The MOOC evaluation data collection and data analysis methods should be determined carefully on the basis of the aim of the evaluation. The MOOC evaluations are subject to bias, which could be reduced using pre-MOOC measures for comparison or by controlling for confounding variables. Future MOOC evaluations should consider using more diverse data sources and data analysis methods. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): RR2-10.2196/12087.

RESUMO

Community-dwelling HIV/AIDS patients in rural Alabama self-monitored (SM) daily HIV risk behaviors using an Interactive Voice Response (IVR) system, which may enhance reporting, reduce monitored behaviors, and extend the reach of care. Sexually active substance users (35 men, 19 women) engaged in IVR SM of sex, substance use, and surrounding contexts for 4-10 weeks. Baseline predictors of IVR utilization were assessed, and longitudinal IVR SM effects on risk behaviors were examined. Frequent (n = 22), infrequent (n = 22), and non-caller (n = 10) groups were analyzed. Non-callers had shorter durations of HIV medical care and lower safer sex self-efficacy and tended to be older heterosexuals. Among callers, frequent callers had lost less social support. Longitudinal logistic regression models indicated reductions in risky sex and drug use with IVR SM over time. IVR systems appear to have utility for risk assessment and reduction for rural populations living with HIV disease.

RESUMO

Language, believed to have originated from actions, not only functions as a medium to access other minds, but it also helps us commit actions and enriches our social life. This fMRI study investigated the semantic and neural representations of actions and mental states. We focused mainly on language semantics (comprehending sentences with action words versus those with mental state words). While in an fMRI scanner, twenty-four healthy, right-handed adult volunteers read a series of sentences with a verb depicting either a mental state (e.g., deceive, persuade) or an action (e.g., punch, kick), and answered a comprehension question that followed. Overall, this task showed brain activation in the left inferior frontal gyrus and in the left posterior superior temporal sulci. While comprehending sentences with mental state terms, participants showed greater activation in left orbitofrontal, and in left precuneus areas. On the other hand, the action sentences recruited more primary motor, left inferior parietal, bilateral occipital, right superior temporal, and right inferior frontal areas. The findings of this study underscore the role of motor and visuospatial involvement in action word representation in the human brain.

RESUMO

Sound measurement of risk behaviors is essential to guide tailored risk reduction strategies as HIV infection patterns shift toward rural minorities, particularly in the southeastern United States where HIV disease remains highly stigmatized. Interactive Voice Response (IVR) systems appear to enhance reports of sensitive behaviors and can support telehealth applications to extend the reach of care in rural, underserved areas. This study evaluated the feasibility and data quality of an IVR telephone reporting system with rural substance users living with HIV/AIDS. Community-dwelling patients were recruited from a nonprofit HIV medical clinic in rural Alabama (N = 35 men, 19 women). Participants engaged in daily IVR reporting of substance use and sexual practices for up to 10 weeks. IVR reports were compared with retrospective Timeline Followback (TLFB) interview reports for the same period. IVR and TLFB reports showed good to excellent agreement for summary measures of alcohol consumption and sexual activity. Agreements for illicit drug use reports were less satisfactory. Reports of monetary spending on alcohol and drugs were significantly higher on the IVR. Most individuals showed good agreements for reports of day-to-day alcohol and drug use and sexual practices. The study established the utility of IVR assessment with rural, disadvantaged adults living with HIV/AIDS who are priority targets for risk reduction interventions.
