Engaging students through online video homework assignments: A case study in a large‐enrollment ecology and evolution course

Online educational videos have the potential to enhance undergraduate biology learning, for example by showcasing contemporary scientific research and providing content coverage. Here, we describe the integration of nine videos into a large‐enrollment (n = 356) introductory evolution and ecology course via weekly homework assignments. We predicted that videos that feature research stories from contemporary scientists could reinforce topics introduced in lecture and provide students with novel insights into the nature of scientific research. Using qualitative analysis of open‐ended written feedback from the students on each video assigned throughout the term (n = 133–229 responses per video) and on end‐of‐quarter evaluations (n = 243), we identified common categories of student perspectives. All videos received more positive than negative comments and all videos received comments indicating that students found them intellectually and emotionally stimulating, accessible, and relevant to course content. Additionally, all videos also received comments indicating some students found them intellectually unstimulating, though these comments were generally far less numerous than positive comments. Students responded positively to videos that incorporated at least one of the following: documentary‐style filming, very clear links to course content (especially hands‐on activities completed by the students), relevance to recent world events, clarity on difficult topics, and/or charismatic narrators or species. We discuss opportunities and challenges for the use of online educational videos in teaching ecology and evolution, and we provide guidelines instructors can use to integrate them into their courses.     

An international basic science and clinical research summer program for medical students

An important part of training the next generation of physicians is ensuring that they are exposed to the integral role that research plays in improving medical treatment. However, medical students often do not have sufficient time to be trained to carry out any projects in biomedical and clinical research. Many medical students also fail to understand and grasp translational research as an important concept today. In addition, since medical training is often an international affair whereby a medical student/resident/fellow will likely train in many different countries during his/her early training years, it is important to provide a learning environment whereby a young medical student experiences the unique challenges and value of an international educational experience. This article describes a program that bridges the gap between the basic and clinical research concepts in a unique international educational experience. After completing two semester curricula at Alfaisal University in Riyadh, Kingdom of Saudi Arabia, six medical students undertook a summer program at St. Boniface Hospital Research Centre, in Winnipeg, MB, Canada. The program lasted for 2 mo and addressed advanced training in basic science research topics in medicine such as cell isolation, functional assessment, and molecular techniques of analysis and manipulation as well as sessions on the conduct of clinical research trials, ethics, and intellectual property management. Programs such as these are essential to provide a base from which medical students can decide if research is an attractive career choice for them during their clinical practice in subsequent years. An innovative international summer research course for medical students is necessary to cater to the needs of the medical students in the 21st century.     

Programmed Instruction: New Bottle for Rediscovered Wine

Programmed instruction is attracting attention at all educational levels. While this approach is new, the educational principles it incorporates are well established: instructional goals are defined in advance, the content is meticulously organized, active student participation is demanded, immediate feedback is provided to students, and each instructional unit is subjected to testing and revision. With its established effectiveness as a vehicle for introducing new topics, and for providing remedial and supplementary instruction, it can free the medical teacher to devote his time to matters which are more deserving of his attention, such as identifying and responding to individual student needs, exploring complex concepts, and working directly with students to provide a model and critical supervision. A more important potential contribution of programming may be that it has reminded us of sound educational precepts which deserve our attention in all forms of instruction.     

"Survivor" torches "Who Wants to Be a Physician?" in the educational games ratings war

We recently developed an educational game for reviewing respiratory physiology in a large classroom. The "Who Wants to be a Physician?" game encouraged medical students to be active participants in the learning process. An evaluation of the game documented that students enjoyed the active format, and the students reported that the game enhanced their ability to understand and retain information. However, the evaluation also revealed that the game had limitations. Specifically, the students recommended the use of multiple-choice questions to match the Medical Board Examination format and to speed up the game (i.e., cover more topics). The students also wanted to increase their level of participation and interaction. Finally, we wanted to emphasize the benefits of peer instruction as a collaborative learning tool. To address these limitations, we designed a new game, "Survivor." Survivor incorporated multiple-choice questions and emphasized peer instruction and a capacity to gather information and solve novel problems. In addition, participation was increased by including the student audience in the game. Finally, an evaluation instrument was utilized to assess the effectiveness of this instructional tool in an academic setting. As a result of these improvements, the evaluation documents that the newly developed tool is a more effective educational game that couples fun and creative excitement with proven and effective educational concepts.     

Inquiry-based training improves teaching effectiveness of biology teaching assistants

Graduate teaching assistants (GTAs) are used extensively as undergraduate science lab instructors at universities, yet they often have having minimal instructional training and little is known about effective training methods. This blind randomized control trial study assessed the impact of two training regimens on GTA teaching effectiveness. GTAs teaching undergraduate biology labs (n = 52) completed five hours of training in either inquiry-based learning pedagogy or general instructional “best practices”. GTA teaching effectiveness was evaluated using: (1) a nine-factor student evaluation of educational quality; (2) a six-factor questionnaire for student learning; and (3) course grades. Ratings from both GTAs and undergraduates indicated that indicated that the inquiry-based learning pedagogy training has a positive effect on GTA teaching effectiveness.     

Use of Learning Media by Undergraduate Medical Students in Pharmacology: A Prospective Cohort Study

The ubiquity of the internet and computer-based technologies has an increasing impact on higher education and the way students access information for learning. Moreover, there is a paucity of information about the quantitative and qualitative use of learning media by the current student generation. In this study we systematically analyzed the use of digital and non-digital learning resources by undergraduate medical students. Daily online surveys and semi-structured interviews were conducted with a cohort of 338 third year medical students enrolled in a general pharmacology course. Our data demonstrate a predominant use of digital over non-digital learning resources (69 ± 7% vs. 31 ± 7%; p < 0.01) by students. Most used media for learning were lecture slides (26.8 ± 3.0%), apps (22.0 ± 3.7%) and personal notes (15.5 ± 2.7%), followed by textbooks (> 300 pages) (10.6 ± 3.3%), internet search (7.9 ± 1.6%) and e-learning cases (7.6 ± 3.0%). When comparing learning media use of teaching vs. pre-exam self-study periods, textbooks were used significantly less during self-study (-55%; p < 0.01), while exam questions (+334%; p < 0.01) and e-learning cases (+176%; p < 0.01) were utilized more. Taken together, our study revealed a high prevalence and acceptance of digital learning resources by undergraduate medical students, in particular mobile applications.     

Anticipation of Personal Genomics Data Enhances Interest and Learning Environment in Genomics and Molecular Biology Undergraduate Courses

An important discussion at colleges is centered on determining more effective models for teaching undergraduates. As personalized genomics has become more common, we hypothesized it could be a valuable tool to make science education more hands on, personal, and engaging for college undergraduates. We hypothesized that providing students with personal genome testing kits would enhance the learning experience of students in two undergraduate courses at Brigham Young University: Advanced Molecular Biology and Genomics. These courses have an emphasis on personal genomics the last two weeks of the semester. Students taking these courses were given the option to receive personal genomics kits in 2014, whereas in 2015 they were not. Students sent their personal genomics samples in on their own and received the data after the course ended. We surveyed students in these courses before and after the two-week emphasis on personal genomics to collect data on whether anticipation of obtaining their own personal genomic data impacted undergraduate student learning. We also tested to see if specific personal genomic assignments improved the learning experience by analyzing the data from the undergraduate students who completed both the pre- and post-course surveys. Anticipation of personal genomic data significantly enhanced student interest and the learning environment based on the time students spent researching personal genomic material and their self-reported attitudes compared to those who did not anticipate getting their own data. Personal genomics homework assignments significantly enhanced the undergraduate student interest and learning based on the same criteria and a personal genomics quiz. We found that for the undergraduate students in both molecular biology and genomics courses, incorporation of personal genomic testing can be an effective educational tool in undergraduate science education.     

It's difficult to change the way we teach: lessons from the Integrative Themes in Physiology curriculum module project

The Integrative Themes in Physiology (ITIP) project was a National Science Foundation-funded collaboration between the American Physiological Society (APS) and the Human Anatomy and Physiology Society (HAPS). The project goal was to create instructional resources that emphasized active learning in undergraduate anatomy and physiology classrooms. The resources (activity modules and professional development) addressed two factors thought to be limiting science education reform: instructors' knowledge of how to implement active learning instruction and time to design innovative curricula. Volunteer instructors with a strong interest in using active learning in their classrooms were recruited to use the ITIP modules and provide ease-of-use feedback and student assessment data. As the study unfolded, instructor attrition was higher than had been anticipated, with 17 of 36 instructors withdrawing. More surprisingly, instructors remaining with the project failed to use the modules and reported specific obstacles that precluded module use, including lack of support from academic leadership, unplanned class size increases and heavy teaching loads, a union strike, insufficient time to develop a mindset for change, inadequate technology/funding, an adverse human subjects ruling, incompatibility of modules with instructors' established content and expectations, and personal factors. Despite the lack of module use and obstacles, 8 of 19 site testers began independently to introduce new active learning instruction into their classrooms. In the larger picture, however, it is important to note that only 8 of the initial 36 volunteers (22%) actually ended up changing their instruction to include opportunities for student active learning. These findings underscore the difficulty of implementing instructional change in college classrooms.     

Evidence That Personal Genome Testing Enhances Student Learning in a Course on Genomics and Personalized Medicine

An emerging debate in academic medical centers is not about the need for providing trainees with fundamental education on genomics, but rather the most effective educational models that should be deployed. At Stanford School of Medicine, a novel hands-on genomics course was developed in 2010 that provided students the option to undergo personal genome testing as part of the course curriculum. We hypothesized that use of personal genome testing in the classroom would enhance the learning experience of students. No data currently exist on how such methods impact student learning; thus, we surveyed students before and after the course to determine its impact. We analyzed responses using paired statistics from the 31 medical and graduate students who completed both pre-course and post-course surveys. Participants were stratified by those who did (N = 23) or did not (N = 8) undergo personal genome testing. In reflecting on the experience, 83% of students who underwent testing stated that they were pleased with their decision compared to 12.5% of students who decided against testing (P = 0.00058). Seventy percent of those who underwent personal genome testing self-reported a better understanding of human genetics on the basis of having undergone testing. Further, students who underwent personal genome testing demonstrated an average 31% increase in pre- to post-course scores on knowledge questions (P = 3.5×10⁻⁶); this was significantly higher (P = 0.003) than students who did not undergo testing, who showed a non-significant improvement. Undergoing personal genome testing and using personal genotype data in the classroom enhanced students'' self-reported and assessed knowledge of genomics, and did not appear to cause significant anxiety. At least for self-selected students, the incorporation of personal genome testing can be an effective educational tool to teach important concepts of clinical genomic testing.     

Improving Education in Medical Statistics: Implementing a Blended Learning Model in the Existing Curriculum

Background

Although recent studies report on the benefits of blended learning in improving medical student education, there is still no empirical evidence on the relative effectiveness of blended over traditional learning approaches in medical statistics. We implemented blended along with on-site (i.e. face-to-face) learning to further assess the potential value of web-based learning in medical statistics.

Methods

This was a prospective study conducted with third year medical undergraduate students attending the Faculty of Medicine, University of Belgrade, who passed (440 of 545) the final exam of the obligatory introductory statistics course during 2013–14. Student statistics achievements were stratified based on the two methods of education delivery: blended learning and on-site learning. Blended learning included a combination of face-to-face and distance learning methodologies integrated into a single course.

Results

Mean exam scores for the blended learning student group were higher than for the on-site student group for both final statistics score (89.36±6.60 vs. 86.06±8.48; p = 0.001) and knowledge test score (7.88±1.30 vs. 7.51±1.36; p = 0.023) with a medium effect size. There were no differences in sex or study duration between the groups. Current grade point average (GPA) was higher in the blended group. In a multivariable regression model, current GPA and knowledge test scores were associated with the final statistics score after adjusting for study duration and learning modality (p<0.001).

Conclusion

This study provides empirical evidence to support educator decisions to implement different learning environments for teaching medical statistics to undergraduate medical students. Blended and on-site training formats led to similar knowledge acquisition; however, students with higher GPA preferred the technology assisted learning format. Implementation of blended learning approaches can be considered an attractive, cost-effective, and efficient alternative to traditional classroom training in medical statistics.     

Teaching cytopathology to second-year medical students. An interactive,case-based approach

OBJECTIVE: To develop and implement an electronic, interactive, case-based cytopathology educational system for second-year medical students. STUDY DESIGN: Ten different learning modules, corresponding to various organ systems in pathology and encompassing the essence of clinical cytopathology, were developed. The modules are software-based, menu-driven, digital programs that are displayed on a computer monitor and can be projected onto a large screen via LCD projectors. Each module takes 15-20 minutes to complete and contains three to four case-based interactive clinical scenarios. Each case contains sequenced, multiple-choice questions with immediate feedback. Each module also includes an atlas mode for viewing all the case images plus additional images to enrich the learning experience. RESULTS: Preliminary feedback from students taking the pathology course has shown encouraging responses. The students enjoyed the practical approach of the modules, finding them easy to use. Their interest level remained high as they discovered how their general medical knowledge could apply to solving real-life clinical cytopathology cases. CONCLUSION: By utilizing these unique instructional modules in the second-year pathology course, medical students learn the application of clinical cytopathology in everyday medical practice. This not only provides them with the theoretical background and morphologic knowledge of the diseases taught but also gives them the ability to apply it in simulated real-life clinical scenarios.     

Measuring the Quality of University Lectures: Development and Validation of the Instructional Skills Questionnaire (ISQ)

In higher education, student ratings are often used to evaluate and improve the quality of courses and professors’ instructional skills. Unfortunately, student-rating questionnaires rarely generate specific feedback for professors to improve their instructional skills. The impact of student ratings on professors’ instructional skills has proven to be low. This study concerns the psychometric properties of the Instructional Skills Questionnaire (ISQ), a new theory-based student-rating-of-teaching questionnaire with specific questions concerning lecturing skills. The ISQ is administered after a single lecture. This way, it serves as a formative feedback instrument for university professors during courses to assist them to improve and (re-) evaluate their skills if necessary. The ISQ contains seven dimensions of professors’ instructional skills and three student (self perceived) learning outcomes. In this study, Dutch students in 75 courses rated three 90-minute lectures (T1, T2 and T3) of their respective professors using the ISQ. In total, 14,298 ISQ-forms were used to rate 225 lectures. The teacher level reliabilities of the seven dimensions were found to be good at each measurement occasion. In addition, confirmatory multilevel factor analysis confirmed a seven dimensional factor structure at the teacher level at each measurement occasion. Furthermore, specific teacher level factors significantly predicted students’ (self-assessed) learning outcomes. These results partly supported the proposed theoretical framework on the relationship between the ISQ teaching dimensions and the student learning process, and provided evidence for the construct validity of the instrument. In sum, the ISQ is found to be a reliable and valid instrument, which can be used by professors and faculty development centers to assess and improve university teaching.     

A student-centred,problem-based curriculum: 5 years' experience.

In 1987, the University of Sherbrooke''s school of medicine implemented a student-centred, problem-based learning (PBL) curriculum. The experience of the first 5 years is reviewed; program goals, the schedule of learning activities, the instructional format and assessment of student learning are described. The new program is more demanding of teachers and requires better faculty training in pedagogy. No new financial resources have been available. The preclinical reform has led to revision of the clerkship, where sessions on clinical reasoning are now based on the PBL philosophy. Student reactions to the program are reported. The Sherbrooke experience has demonstrated that it is both possible and feasible to shift from a traditional to a problem-based curriculum.     

Enhancing the learning of evolutionary anthropology skills by combining student‐active teaching with actual and virtual immersion of Master's students in fieldwork,laboratory practice,and dissemination

Higher education in evolutionary anthropology involves providing students with in‐depth knowledge of biological and cultural heritage sites and collections that are frequently inaccessible. Indeed, most sites, fossils, and archaeological remains can be visited or manipulated only rarely and solely by specialists with extensive experience. Owing to the development of 3D and medical imaging techniques, this fragile heritage is now more widely accessible, and in a dynamic way. However, exclusive adoption of virtual teaching and learning has a negative impact on student engagement and, naturally, on exchanges with instructors, and thus cannot be used without some reservations. In the ITAP (Immersion dans les Terrains de l’Anthropologie biologique et de la Préhistoire) project of the higher education STEP (Soutien à la Transformation et à l’Expérimentation Pédagogiques) transformation program at the University of Bordeaux, we combine student‐active teaching with Master''s students fully immersed in ongoing fieldwork, laboratory study, and dissemination of research results in order to develop more individually shaped learning curricula and to foster both professional and new interdisciplinary skills. Here, we present examples of experiments conducted in the ITAP project using both authentic and virtual collections of archaeological, experimental, and reference materials that help to break down the barriers between research activities and higher education, as well as providing a more general appraisal of the appropriate use of virtual tools in higher education by combining them with real‐life situations.     

Teaching advanced genetics without lectures

In an effort to increase student engagement and therefore student learning, an advanced genetics course was developed in which traditional lectures were eliminated. Instead, students were required to complete reading assignments before each class meeting, and those readings were then the topic of group discussion. Assigned readings alternated between text assignments and articles from the primary literature. Students were made accountable for their own preparation by the administration of a quiz at the start of each class. Group discussion of the topics engaged students in the learning process and readministration of the quiz at the end of class allowed them to benefit from the group interaction and understanding. Interspersing text readings and primary literature led to student understanding of how genetic knowledge is acquired and interpreted and how experimental detail leads to the construction of general models.     

Thoughts on Learning and Teaching in the First Two Years of the Medical Curriculum

Suggestions for improvement of the educational program in the first two years of the medical curriculum are made in the light of simultaneous experiences as teacher and student. The learning needs of the student should be given more consideration. Many of the present learning-teaching problems could be solved by closer communication and collaboration between instructors teaching the same students coupled to an official recognition of the value of good teaching. In spite of a multiplicity of courses and basic science departments, the student is a single person with a rather limited goal. He is required to learn and remember a vast amount of detailed factual information during his first two years of the medical curriculum. The medical student should be reinstated as an integral human component of the structure and functioning of each department. This is a difficult task because the dual functions of research in a specialized discipline and undergraduate medical teaching frequently pull an individual''s or department''s activities in opposite directions and lead to administrative problems.     

E-learning: is there anything special about the "E"?

E-learning has been widely utilized in medical education and suggested by some proponents to represent a fundamental advance in educational methodology. We challenge this conclusion by examining e-learning in the context of broader learning theories, specifically as they relate to instructional design and methods. Core tenets of educational design are applied to e-learning in a unified model for instructional design, and examples of e-learning technologies are examined in the context of medical education, with reflections on research questions generated by these new modalities. Throughout, we argue that e-learning is a tool that, when designed appropriately, can be used to meet worthy educational goals.     

A multimedia CD-ROM tool to improve student understanding of bile salts and bilirubin metabolism: evaluation of its use in a medical hybrid PBL course

Over the last 35 years our understanding of bile salts, bilirubin metabolism, and hepatobiliary transport has progressively increased. From 1965 to the end of 2002, 3,610 articles and review papers have been published on hepatobiliary and enterocyte transport of bile salts. However, there is a lack of information in the content of current textbooks about hepatobiliary physiology, bile salt transporters, bile formation, mechanisms underlying cholestasis, and drug-induced liver injury. The use of an integrated multimedia program on the liver covering these gaps in textbooks may be useful to student learning. This study aims to 1) assess student views on a multimedia CD-ROM ("The Liver") integrating basic and clinical sciences related to the liver, bile salts, and bilirubin metabolism, 2) assess the usefulness of problem-based learning (PBL) cases included in the multimedia CD-ROM, and 3) assess student learning before and after use of the multimedia CD-ROM. A total of 106 first-year medical students (27 with and 79 without a prior university degree) at the University of Melbourne participated in this study. Students were tested on the liver, bile salts, and bilirubin metabolism before and after using the multimedia CD-ROM. After completing the multimedia CD-ROM, each student filled out a 5-point Likert scale questionnaire evaluating the features of the program and its usefulness to their learning. Results show that the aims of the package were clear to participants, the contents were logically organized and clear, the key concepts were easy to identify, the contents were pitched to an appropriate level, and the package was interactive and encouraged participants to reflect on their learning. Students also agreed that the assessment tools used in the program and the feedback provided were meaningful and helpful to their learning. No differences were found when responses were compared on the basis of academic background, gender, citizenship, or first language of participants. Students agreed that the PBL cases in the CD-ROM kept them engaged, were useful to their learning, and matched with the overall philosophy of the program. Compared with graduate-entry students (those with a prior university degree), school leavers (those with no prior university degree) showed a more positive attitude toward the PBL cases included in the multimedia CD-ROM and agreed that cases kept them engaged (P = 0.033). Students who completed the test after using the multimedia CD-ROM scored higher compared with those who completed the test before using the multimedia CD-ROM (P < 0.001). In conclusion, using bile salts, bilirubin metabolism, and their hepatobiliary transport as an example, the incorporation of a multimedia CD-ROM into the first-year medical course has the potential to improve student understanding of the main concepts in a variety of body systems.     

Katalyst: development of a fifth-grade novel approach to health and science experiential learning

The Katalyst intervention program was piloted in fifth-grade classrooms at two Appalachian schools during the 2017–18 academic year as a potential educational resource to tackle the rising rates of obesity and chronic diseases in this region. The program consisted of four 60-minute modules, each based on a specific organ system. Each module incorporated hands-on lessons in physiology with an emphasis on preventing chronic disease through diet, nutrition, physical activity, and abstinence from drug and tobacco use. The modules were led by medical students and undergraduate volunteers who completed a two-day training. A 37-item survey assessing knowledge and perceptions regarding healthy lifestyles was administered to fifth grade participants prior to and following the intervention in order to assess the impact of the program. Additionally, educators at intervention schools were given a questionnaire post-intervention to provide feedback on the program. This paper describes the rationale, program design and execution, and conclusion of the Katalyst intervention program. It is anticipated that this program will reinforce current educational standards regarding diet, nutrition and physical activity in order to empower target students to establish healthy lifestyle behaviors and that programs modeled after the Katalyst curriculum may serve as a novel, viable option to health educators.
