RESUMO
This paper presents a phenomenographic investigation on students' experiences about research and poster presentations in a workshop-based undergraduate research experience with a focus on how the experience connects to the Science and Engineering Practices (SEPs) of the NRC A Framework for K-12 Science Education and the principles of CUREs. This provides insight into how these structured research experiences reflect particular SEPs and also elements of scientific practice that are not captured in the SEPs as they have been formulated previously. This work showcases the importance of future applications, failure, and creativity as additional science practices necessary for students to engage in authentic science. The SEPs and the additional elements of scientific practice are related to how students experience meaningful learning in the cognitive, psychomotor, and affective domains. Students highlighted the components of CUREs: importance of contributing relevant discoveries as a motivation for their research, the value of repetition and iteration in ensuring reliable and valid results, and the role of collaboration in seeing new perspectives and solving problems. As a result of presenting their results through a poster, students reported deeper understanding of their research topic, increased ability to articulate scientific concepts, and a better understanding of how to create a visually appealing poster. Students changed the vocabulary they used in their presentations to fit the knowledge level of their audience and highlighted their data in figures and explained other parts of their work in text. Moreover, they saw the poster as an outlet for their creativity.
RESUMO
Inquiry-based learning (IBL) is a promising educational framework that is understudied in graduate medical education. To determine participant satisfaction and engagement with phases of an IBL postgraduate education program, a mixed-methods study collected data via survey statements and open-ended responses. The authors included participants attending an intensive care medicine (ICM) IBL program from May to November 2020. Quantitative outcomes included participants' satisfaction with the IBL format and impact of engagement with IBL on the learning experience. Qualitative outcomes explored determinants of engagement with IBL phases and the impact on the learning experience. Of 378 attendees, 167 submitted survey responses (44.2%). There was strong agreement relating to overall satisfaction (93.4%). Responses indicated engagement with "orientation" (94.6%), "conceptualization" (97.3%), "discussion" (91.1%), and "conclusion" (91.0%) but limited engagement with the "investigation" phase (48.1%). Greater engagement with IBL phases had positive impacts, with repeat attenders having clearer learning objectives (79.1% vs. 56.6%, P < 0.05) and enhanced learning through collaborative discussion (65.9% vs. 48.7%, P < 0.05). Qualitative analysis showed that ICM learners value active learning principles, clear objectives, and a safe environment to expand their "knowledge base." Sessions facilitated "clinically relevant learning," with application of theoretical knowledge. Learners transformed and "reframed their understanding," using the input of others' experiences. ICM learners were highly satisfied with the IBL format and reported valuable learning. Participants engaged strongly with all IBL phases except the investigation phase during the sessions. IBL facilitated learners' active construction of meaning, facilitating a constructivist approach to learning.NEW & NOTEWORTHY An inquiry-based learning (IBL) program was launched as part of a novel binational intensive care medicine education program. Postgraduate intensive care medicine practitioners participated in this education intervention, where facilitated group discussions explored core intensive care medicine concepts. Survey responses indicated overall satisfaction, engagement with the IBL format, and a constructivist approach to learning. This study provided new insights into the benefits and challenges of an IBL program in the context of practicing clinicians.

Notwithstanding the advantages of incorporating Augmented Reality (AR) in education, AR's concrete uses as compared to other technologies are not fully recognised. Moreover, many of the existing studies have neglected to examine the impact of pedagogy and its corresponding instructional models, whilst implementing AR in teaching and learning. In leveraging the affordances of AR, an inquiry-based learning framework, referred to as QIMS, was proposed in this study. A learning package was developed on the topic of plant reproduction for primary 5 students (aged 11-12) based on the QIMS framework. Using a quasi-experimental approach, this study evaluated three conditions (AR and QIMS; QIMS; Non-AR and Non-QIMS) for a series of science lessons in a primary school. 117 students took part in this study. The quantitative results showed that although there was no statistically significant difference in students' academic performance when AR was used, students' self-directed learning and creative thinking skills increased significantly after partaking in the QIMS inquiry-based lessons. The usage of AR and QIMS had a significant effect in increasing students' critical thinking and knowledge creation efficacy skills. Moreover, in view of students' academic outcomes, the integration of QIMS and AR proved to be more beneficial to low-progress students. Qualitative analysis of the interview data from teachers and students aids in accounting for the quantitative results and indicate productive implementation strategies. The findings of this study will guide the design of future AR interventions, by providing insights for both researchers and practitioners on how to integrate and implement AR with pedagogical approaches.
RESUMO
This article examines student experiences in a workshop-based undergraduate research experience studying the activity and inhibition of salivary amylase that provides students with the chance to participate in authentic scientific research prior to the start of their undergraduate studies, following the structure of a course-based undergraduate research experience (CURE). Understanding student experiences at this point in their studies is important because research experiences at the beginning of university studies have been shown to increase retention in STEM. This study utilizes meaningful learning and situated cognition as theoretical frameworks and phenomenography as a methodological framework, applied to data from semi-structured interviews with six students. The student experiences were characterized as an outcome space detailing the degree of their meaningful learning with respect to their understanding of the research process, nature of science, and the poster creation and presentation process. The findings highlight that meaningful learning is achieved when research is connected to students' personal lives and/or future job interests. The research process and nature of science must also be made explicit to students by emphasizing the iterative nature of research and highlighting distinctions between science and non-science fields. All participating students displayed an understanding that anyone can partake in science anywhere. Implications for building on this work to develop an understanding of students' sense of belonging and self-identity are also discussed.
RESUMO
This research examined the differential motivational effects of a pre-college science enrichment program delivered in both online and in-person learning formats. Using self-determination theory as a guiding framework, we hypothesized that (a) students would exhibit growth in their perceived satisfaction of needs for autonomy, competence, and relatedness, (b) online learning would be associated with greater growth in autonomy, and (c) in-person learning would be associated with greater growth in both competence and relatedness. Using a sample of 598 adolescent participants, results of latent growth curve modeling indicated that satisfaction of the three needs grew unconditionally over the course of the program. However, format type was unrelated to growth in need satisfaction. Rather, this effect was found to be conditional upon the type of science project undertaken by students: astrophysics students exhibited significantly greater autonomy growth when receiving online instruction than did biochemistry students. Our findings suggest that online science learning can be just as effective in motivating students as in-person learning provided that the learning tasks are conducive to remote instruction.
RESUMO
The intervention study presented in this paper explored pre-service science teachers' (PSSTs) understanding of scientific inquiry (SI) and scientific practices (SPs) during a laboratory application in science education course. Thirty-nine secondary school PSSTs, who study in the Science Education Department in a public university in Turkey, enrolled in a 14-week-long course and volunteered to participate in the study. The participants were exposed to a method is called the 4-phase implementation that includes laboratory-based inquiry activities addressing SI and SPs and they completed microteaching presentations. Their understanding of SI and SPs was examined through the course period. The main data sources included Views about Scientific Inquiry (VASI) Instrument and concept maps were used to track the changes in these understandings. The findings indicated that PSSTs had inadequate understanding of inquiry on some aspects even after the treatment. Yet, the method had positive impact in PSSTs' understanding inquiry especially in terms of facilitating the comprehension that scientific investigations begin with questions, there is no single method in investigations, and explanations are derived from collected data. The concept maps created by some of the participants also supported these results and revealed a more coherent and holistic understanding of SPs by integrating both epistemic and social components into their maps. However, PSSTs did not seem to have totally understood other aspects of inquiry including the inquiry procedures, the research conclusions, and the difference between data and evidence. Further implications are critically discussed in terms of designing future laboratory applications for science education courses.
RESUMO
Simulations have long played an important role in neurobiology education. This paper describes the design-research process that led to development of two popular simulation-based neurobiology modules used in undergraduate biology classes. Action Potentials Explored, and the more in-depth and quantitative Action Potentials Extended, are the third generation of neurobiology teaching simulations the author has helped develop. The paper focuses on how we used the idea of constraining simulations as a way of tuning the modules to different student populations. Other designers of interactive educational materials may also find constraint a useful lens through which to view designs.
RESUMO
We report a new online suite of tools that enables inquiry-based active-learning activities to develop students' representational competence about atomic orbitals. Orbital Explorer is Web site hub for the visualization and interactive investigation of atomic orbital properties. Orbital Explorer contains two integrated tools, namely, Atomic Orbital Explorer, which enables one to visualize and interrogate individual atomic orbitals, and Orbital RDF Comparison, which enables one to make a more detailed quantitative comparison of orbital energies and properties of orbital radial distribution functions (RDFs). In addition, we present an original chemistry educational gamification design, BingOrbital, constructed in a format resembling Bingo (American version). The game aims to reinforce the recognition of atomic orbitals based on the RDF and 3D isosurface and has been applied as an engaging retrieval practice tool. A companion set of example activities that use the Orbital Explorer and BingOrbital game have been presented in another article.
RESUMO
Atomic orbitals represent an essential construct used to develop chemical bonding models, upon which other more advanced chemistry topics are built. In this article, we share a series of active-learning activities and a gamified approach to develop students' representational competence about atomic orbitals and to engage students in learning the properties of atomic orbitals. These properties are essential for understanding an array of fundamental concepts such as penetration and shielding, relationships such as periodic trends, and models used to describe chemical bonding. The activities employ an inquiry-based approach to engage students in exploring the relationship between atomic orbitals' spatial properties and quantum numbers. The activities guide students to collect data to verify periodic trends and construct electronic configurations. The activities utilize Orbital Explorer Web site for visualization, comparison and analysis of atomic orbitals. The Orbital Explorer Web site is described in a related Technology Report. The activities and the game are suitable to be conducted in both in-person and remote-teaching settings.
RESUMO
The COVID-19 pandemic redefined how chemistry laboratories were taught. It also introduced a racial health disparity for Black and Brown people. The General Chemistry I laboratory curriculum at a Historically Black College and University (HBCU) in Baltimore, MD, was redesigned to meet student needs during this challenging time. While surrounded by civil unrest and uncertainty, we wanted to reach our underrepresented students in a way that they felt seen and heard. "The Mystery of Mr. Johnson" series was designed to reinforce the role chemistry can serve in advancing equity in their community. This interconnected series of three experiments (Solutions, Titration, Spectroscopy) developed chemistry laboratory skills which were applied to diabetes, a COVID-19 comorbidity, and health disparity highly prevalent in Baltimore. "The Mystery of Mr. Johnson" series provided opportunities for students to gain exposure to the role of chemistry in addressing a health disparity that impacts their community. The culminating project was a public service announcement to communicate lifestyle changes and the prevalence of diabetes in the black community.
RESUMO
Group Level Assessment (GLA) is a qualitative, participatory research methodology that can be used within science education, specifically to meet the Science and Engineering Practices dimension of the K-12 Next Generation Science Standards. In contrast to traditional qualitative research methods, GLA is a concrete methodological tool intended for large groups. GLA follows a 7-step process in which diverse stakeholders work together to generate, analyze and prioritize ideas that lead to action planning. Emphasizing personal relevance, shared decision making, systematic inquiry, and collaboration in the design and process, GLA is best positioned conceptually and theoretically within community-based participatory research and inquiry-based learning approaches. The purpose of this manuscript is to describe how GLA can be utilized as an innovative methodology to incorporate students' lived experiences in science education. We describe how to conduct GLA and provide a case example of GLA in action conducted as part of a larger science education program with students and teachers in STEM.
RESUMO
Over the past decade, laboratory courses have made a fundamental shift to inquiry-based modules and authentic research experiences. In many cases, these research experiences emphasize addressing novel research questions. Insects are ideal for inquiry-based undergraduate laboratory courses because research on insects is not limited by regulatory, economic, and logistical constraints to the same degree as research on vertebrates. While novel research questions could be pursued with model insect species (e.g., Drosophila, Tribolium), the opportunities presented by non-model insects are much greater, as less is known about non-model species. We review the literature on the use of non-model insect species in laboratory education to provide a resource for faculty interested in developing new authentic inquiry-based laboratory modules using insects. Broader use of insects in undergraduate laboratory education will support the pedagogical goals of increased inquiry and resesarch experiences while at the same time fostering increased interest and research in entomology.

This paper is in response to the article entitled "Identifying potential types of guidance for supporting student inquiry when using virtual and remote labs in science: a literature review" by Zacharia et al. (2015). In their review, Zacharia et al. (2015) adopted de Jong and Lazondo's (2014) framework of five inquiry phases for online labs: orientation, conceptualization, investigation, conclusion, and discussion. Zacharia et al. reviewed the literature on Computer-supported Inquiry Learning (CoSIL), and identified best practices for each phase. They concluded, for example, that the orientation/conclusion/discussion phases received the least amount of guidance, while there were many more tools and strategies for providing guidance in the conceptualization/investigation phases. In this paper, we adopt the same inquiry framework as Zacharia et al. (2015) and report strategies that we learned from STEM faculty about how they supported and guided virtual student lab-based learning in these five phases during the recent COVID-19 shutdown. While Zacharia et al. identified tools and processes for enabling all five inquiry phases, add additional practical examples of faculty implementing these phases online as part of COVID-19 emergency remote teaching, and we provide insights for extending the 5-phase framework for future research.
RESUMO
Curriculum-based undergraduate research experiences (CUREs) have been shown to increase student retention in STEM fields and are starting to become more widely adopted in chemistry curricula. Here we describe a 10-week CURE that is suitable for a second-semester organic chemistry laboratory course. Students synthesize small molecules and use protein-observed 19F (PrOF) NMR to assess the small molecule's binding affinity to a target protein. The research project introduced students to multistep organic synthesis, structure-activity relationship studies, quantitative biophysical measurements (measuring Kd from PrOF NMR experiments), and scientific literacy. Docking experiments could be added to help students understand how changes in a ligand structure may affect binding to a protein. Assessment using the CURE survey indicates self-perceived skill gains from the course that exceed gains measured in a traditional and an inquiry-based laboratory experience. Given the speed of the binding experiment and the alignment of the synthetic methods with a second-semester organic chemistry laboratory course, a PrOF NMR fragment-based ligand discovery lab can be readily implemented in the undergraduate chemistry curriculum.
RESUMO
Over the last 25 years, reforms in undergraduate biology education have transformed the way biology is taught at many institutions of higher education. This has been fueled in part by a burgeoning discipline-based education research community, which has advocated for evidence-based instructional practices based on findings from research. This perspective will review some of the changes to undergraduate biology education that have gained or are currently gaining momentum, becoming increasingly common in undergraduate biology classrooms. However, there are still areas in need of improvement. Although more underrepresented minority students are enrolling in and graduating from biology programs than in the past, there is a need to understand the experiences and broaden participation of other underserved groups in biology and ensure biology classroom learning environments are inclusive. Additionally, although understanding biology relies on understanding concepts from the physical sciences and mathematics, students still rarely connect the concepts they learn from other STEM disciplines to biology. Integrating concepts and practices across the STEM disciplines will be critical for biology graduates as they tackle the biological problems of the twenty-first century.

The laboratory course is an excellent venue to apply content, practice inquiry, improve critical thinking, practice key clinical skills, and work with data. The use of inquiry-based course projects allows for students to propose open ended questions, form a hypothesis, design an experiment, collect data, analyze data, draw conclusion, and present their findings. This comprehensive experience is ideal for a capstone (senior level) laboratory course that is the culmination of 4 yr of study in the degree. At Michigan State University, the capstone laboratory has incorporated a formal course-based research experience in human physiology. The rationale and logistics for running such an experience are described in this paper.

Design of undergraduate laboratory courses that provide meaningful research-based experiences enhance undergraduate curricula and prepare future graduate students for research careers. In this article, a Course-based Undergraduate Research Experience (CURE) laboratory module was designed for upper-division undergraduate biochemistry and chemistry students. The laboratory module enabled students to build upon recently published data in the literature to decipher atomistic insight for an essential protein-protein interaction in human biology through the use of biomolecular NMR spectroscopy. Students compared their results with published data with the goal of identifying specific regions of the protein-protein interaction responsible for triggering an allosteric conformational change. The laboratory module introduced students to basic and advance laboratory techniques, including protein purification, NMR spectroscopy, and analysis of protein structure using molecular visualization software.
RESUMO
The distributed pharmaceutical analysis laboratory (DPAL) is a collaboration between 30 academic institutions around the world, whose goal is to determine the quality of medicines collected from partner organizations in low- and middle-income countries (LMICs). Institutions complete system suitability for a high-performance liquid chromatography (HPLC) system using United States Pharmacopeia (USP)-traceable reference standards, and are then approved to analyze batches of samples that are collected in LMICs by covert shoppers. Open Science Framework (OSF) allows DPAL participants access to resources for the program including an HPLC methodology manual, a wiki with HPLC troubleshooting information, detailed checklists and Excel templates for system suitability and sample assay, as well as steps for reporting results. Participants incorporate the DPAL program into their academic curriculum as undergraduate research or via lab activities for analytical chemistry or instrumental analysis courses. Over a thousand samples have been analyzed through DPAL in the last three years, and 168 samples with quality problems have been discovered, including falsified acetaminophen, adulterated amoxicillin-clavulanate and doxycycline, and substandard losartan. These quality problems are reported to the medicine regulatory agencies in the countries of origin and the WHO Rapid Alert System for further action. This real-world program gives students a hands-on opportunity to see the importance of analytical metrics taught in the classroom.
RESUMO
This study focuses on science teachers' first encounter with computational modeling in professional development workshops. It examines the factors shaping the teachers' self-efficacy and attitudes towards integrating computational modeling within inquiry-based learning modules for 9th grade physics. The learning modules introduce phenomena, the analysis of measurement data, and offer a method for coordinating the experimental findings with a theory-based computational model. Teachers' attitudes and self-efficacy were studied using survey questions and workshop activity transcripts. As expected, prior experience in physics teaching was related to teachers' self-efficacy in teaching physics in 9th grade. Also, teachers' prior experience with programming was strongly related to their self-efficacy regarding the programming component of model construction. Surprisingly, the short interaction with computational modeling increased the group's self-efficacy, and the average rating of understanding and enjoyment was similar among teachers with and without prior programming experience. Qualitative data provides additional insights into teachers' predispositions towards the integration of computational modeling into the physics teaching.
RESUMO
BACKGROUND: Biomedicine needs innovative professionals. Inquiry-based learning (IBL) aims to develop higher order thinking skills, such as creativity and research. Stimulatory techniques and interprofessional education, which requires students from different fields to collaborate, also enhances creativity. In this study, the effectiveness of an interprofessional IBL course that introduces a creativity workshop based on stimulatory techniques to develop creative and research skills is examined. METHODS: 529 undergraduate human biology and medical students performed the interprofessional IBL course, 198 with the creativity workshop and 331 without. Students' perceptions of learning processes and outcomes were assessed in surveys and focus groups by the authors of this study. As well, the final learning results from both groups of students were analyzed by the teachers of the course and the researchers. RESULTS: The results show that the open IBL approach promoted the development of these skills, interprofessionality acted as a creativity enhancer and stimulatory techniques contributed to improve the learning outcomes. CONCLUSIONS: This study provides insight into how open interprofessional IBL fosters acquisition of complex skills and knowledge, pointing out the benefits and limitations of this approach in health sciences studies.
