Can medical students teach? A near-peer-led teaching program for year 1 students

The General Medical Council states that United Kingdom graduates must function effectively as educators. There is a growing body of evidence showing that medical students can be included as teachers within a medical curriculum. Our aim was to design and implement a near-peer-led teaching program in an undergraduate medical curriculum and assess its acceptability among year 1 students. Students received six tutorials focusing on aspects of cardiac, respiratory, and blood physiology. Tutorials ran alongside standard module teaching. Students were taught in groups of ～30 students/group, and an active teaching approach was used in sessions where possible. Using anonymous evaluations, student feedback was collected for the program overall and for each tutorial. The program was voluntary and open to all first-year students, and 94 (of 138) medical students from year 1 at Brighton and Sussex Medical School were recruited to the study. The tutorial program was popular among students and was well attended throughout. Individual tutorial and overall program quantitative and qualitative feedback showed that students found the tutorials very useful in consolidating material taught within the module. Students found the small group and active teaching style of the near-peer tutors very useful to facilitating their learning experience. The end-of-module written examination scores suggest that the tutorials may have had a positive effect on student outcome compared with previous student attainment. In conclusion, the present study shows that a near-peer tutorial program can be successfully integrated into a teaching curriculum. The feedback demonstrates that year 1 students are both receptive and find the additional teaching of benefit.     

How should we be selecting our graduate students?

We use many quantitative undergraduate metrics to help select our graduate students, but which of these usefully discriminate successful from underperforming students and which should be ignored? Almost everyone has his or her own pet theory of the most predictive criteria, but I hoped to address this question in a more unbiased manner. I conducted a retrospective analysis of the highest- and lowest-ranked graduate students over the past 20 years in the Tetrad program at the University of California at San Francisco to identify undergraduate metrics that significantly differed between these groups. Only the number of years of research experience and subject graduate record exams (GREs) were strong discriminators between the highest- and lowest-ranked students, whereas many other commonly used admissions metrics (analytical, verbal, and quantitative GREs, grade point average, and ranking of undergraduate institution) showed no correlation with graduate performance. These are not necessarily the same criteria that matter at other graduate programs, but I would urge faculty elsewhere to conduct similar analyses to improve the admissions process and to minimize the use of useless metrics in selecting our students.     

Racism within the Canadian university: Indigenous students’ experiences

This article extends the investigation and understanding of the impact that everyday racism/microaggressions can have on the academic experience of Indigenous students by examining the racial climate of a major Canadian university to learn about the nature of anti-Indigenous racism. The data from seventeen interviews with students at McMaster University provide a deeper understanding of how Indigenous students perceive and experience racism within the university environment – including levels, impacts and coping mechanisms – and highlight the potential for racism to have a continuing impact on equality and access to education for Indigenous peoples. Subtle, modern racism is playing an active role in the daily lives of Indigenous university students, affecting both their academic and personal success. Despite increasing levels of successful degree completion and the creation of strong support systems, Indigenous students are consistently faced with barriers, including interpersonal discrimination, frustration with the university system and feelings of isolation.     

How to help students understand physiology? Emphasize general models

Students generally approach topics in physiology as a series of unrelated phenomena that share few underlying principles. In many students' view, the Fick equation for cardiac output is fundamentally different from a renal clearance equation. If, however, students recognize that these apparently different situations can be viewed as examples of the same general conceptual model (e.g., conservation of mass), they may gain a more unified understanding of physiological systems. An understanding of as few as seven general models can provide students with an initial conceptual framework for analyzing most physiological systems. The general models deal with control systems, conservation of mass, mass and heat flow, elastic properties of tissues, transport across membranes, cell-to-cell communication, and molecular interaction.     

Do majoring subjects affect the morningness-eveningness preference by students?

Women preferred morningness significantly more than men. Differences in scores between both sexes became greater in order of the phase points of 'rising time,' 'peak of activities,' and 'falling-to-sleep time,' suggesting that oscillator(s) of men are more easily free-running than those of women. Women majoring in natural sciences or agriculture preferred morningness significantly more than women majoring in humanities, economics, or education.     

Does gender influence learning style preferences of first-year medical students?

Students have specific learning style preferences, and these preferences may be different between male and female students. Understanding a student's learning style preference is an important consideration when designing classroom instruction. Therefore, we administered the visual, auditory, reading/writing, kinesthetic (VARK) learning preferences questionnaire to our first-year medical students; 38.8% (97 of 250 students) of the students returned the completed questionnaire. Both male (56.1%) and female (56.7%) students preferred multiple modes of information presentation, and the numbers and types of modality combinations were not significantly different between genders. Although not significantly different, the female student population tended to be more diverse than the male population, encompassing a broader range of sensory modality combinations within their preference profiles. Instructors need to be cognizant of these differences and broaden their range of presentation styles accordingly.     

Digital technology to support students’ socioscientific reasoning about environmental issues

Scientific expertise and outcomes often give rise to controversy. An educational response that equips students to take part in such discussions is the teaching of socially acute questions (SAQs). With SAQs, the understanding of uncertainty, risk and how knowledge is developed is central. This study explores the way in which students from different disciplines and different continents are brought together via a digital platform to explore SAQs about environmental issues (a green algae outbreak linked to release of fertilisers along the coast of Brittany; the construction of a desalination plant near Melbourne to produce freshwater; and changes in meat consumption on a global scale, with regard to population projections in 2050). We have developed frameworks for looking at the quality of the collective reasoning and at the nature of students’ interactions, so that we can analyse the organisation of the learning communities and the building of collegial expertise. The results show that interdisciplinary discussions, especially on an international scale, foster the understanding of complex situations. In this paper, we discuss the modalities of one didactic scenario to enhance critical thinking and collaborative work, and to provide space for learners to support argumentation.     

Male‐female differences in family size preferences among college students

Abstract

Three dimensions of isolated spousal separation largely determine its fertility impact: (1) length, (2) “completeness” (degree to which it is eliminating fecundability during fecundable months), and (3) its timing as defined by the reproductive state of the wife at its start. While it is obvious that by starting when the wife is in the fecundable state its net delaying of next conception is maximized, it is much less clear with which reproductive state its start should coincide in order to minimize its fertility impact. By means of a simple model, it is shown that for minimum impact a separation should start later in a pregnancy the longer is post‐partum anovulation, the higher is the level of intrauterine mortality, and the shorter is the period of separation. Conditions of natural fertility are assumed.     

Disorders of top–down cognitive control in students with learning difficulties

The model of fixed set (for Uznadze’s paradigm) was used to estimate the functional activity of the cortico-thalamic system of selective attention and cortico-hyppocampal system of emotional and volitional activity in second-year medical students with learning difficulties (n = 20). The control group (n = 30) consisted of successfully studying students of the same year. We observed a significant reduction of induced reactions of neocortical EEG α oscillations in response to the facial stimuli or conditioning Go/NoGo signals in underperforming students. This indicates a decrease in the functional activity of the corticothalamic system of selective attention, i.e., weakening of the top–down cognitive control. This disorder is the psychophysiological basis of cognitive difficulties in the learning process. The amplitude of θ-range cortical potentials in underperforming students is significantly higher than that in the control group, i.e., the level of functional activity of the cortico-hippocampal system is higher, which indicates a higher level of stress. These findings make it possible to conclude that psychophysiological laboratory studies should be used as a supporting tool for high school teachers and psychologists during their work with students with learning difficulties.     

Assessing students’ performances in decision-making: coping strategies of biology teachers

Decision-making in socioscientific issues (SSI) constitutes a real challenge for both biology teachers and learners. The assessment of students’ performances in SSIs constitutes a problem, especially for biology teachers. The study at hand was conducted in Germany and uses a qualitative approach following the research procedures of grounded theory to focus on teachers’ concepts and, especially, coping strategies in assessment concerning students’ decision-making in SSIs. Semi-structured interviews with six teachers, in combination with video-vignettes, were used for data generation. The results show predominantly defensive strategies when teachers are confronted with the assessment of students’ performances in SSIs. These results and implications for teacher education and teacher training are discussed.     

The impacts of the Free Semester program on students’ exam nervousness

I examine the impacts of the Free Semester (FS) program, which is an exam-free semester for middle school students in South Korea, on students’ level of exam nervousness. I use a difference-in-differences approach that exploits the variation in FS-implementation across middle schools to estimate these impacts. I find that the FS program has statistically significant impacts on relieving exam nervousness during the semester in which it is run. In contrast, I find no statistically significant average medium-run impacts of the program. My subgroup analyses suggest that the reduction in exam nervousness during the FS is driven largely by high-achieving students.
