Female mice fed a folic acid deficient diet and 1% succinyl sulfathiazole exhibited many of the characteristics common to human folic acid deficiency, including decreased plasma and RBC folate, increased plasma homocysteine, and poor reproductive outcomes. Thus, an excellent model has been created to investigate the mechanism(s) underlying the origin of birth defects related to folic acid deficiency.

Self-efficacy is defined as a person's beliefs in his or her own abilities to successfully complete a task and has been shown to influence student motivation and academic behaviors. More specifically, anatomical self-efficacy is defined as an individual's judgment of his or her ability to successfully complete tasks related to the anatomy curriculum; these include dissecting, learning anatomical concepts, and applying anatomical knowledge to clinical situations. The purpose of this study was to investigate the influence of anatomical self-efficacy on the academic performance of students enrolled in a medical gross anatomy course. To obtain students' anatomical self-efficacy ratings, surveys containing the same anatomical self-efficacy instrument were completed by first-year medical students at a southeastern United States allopathic medical school after each of four gross anatomy assessments. Additional data collected included student demographic information, Medical College Admission Test(®) (MCAT(®)) scores, and anatomy assessment scores, both written examination and laboratory practical. To investigate the potential predictive nature of self-efficacy for academic performance on both the written examination and the laboratory practical components of medical anatomy assessments, hierarchical linear regression analyses were conducted. For these analyses, academic ability (defined as the sum of the physical sciences and biological sciences MCAT scores) was controlled. The results of the hierarchical linear regressions indicated that all four laboratory practical scores were predicted by the corresponding self-efficacy ratings, while two (i.e., thorax/abdomen and pelvis/lower limb) of the four written examination scores were predicted by the corresponding self-efficacy ratings (P ≤ 0.05).

Students learn and process information in many different ways. Learning styles are useful as they allow instructors to learn more about students, as well as aid in the development and application of useful teaching approaches and techniques. At the undergraduate level there is a noticeable lack of research on learning style preferences of students enrolled in gross anatomy courses. The Index of Learning Styles (ILS) questionnaire was administered to students enrolled in a large enrollment undergraduate gross anatomy course with laboratory to determine their preferred learning styles. The predominant preferred learning styles of the students (n = 505) enrolled in the gross anatomy course were active (54.9%), sensing (85.1%), visual (81.2%), and sequential (74.4%). Preferred learning styles profiles of particular majors enrolled in the course were also constructed; analyses showed minor variation in the active/reflective dimension. An understanding of students' preferred learning styles can guide course design but it should not be implemented in isolation. It can be strengthened (or weakened) by concurrent use of other tools (e.g., flipped classroom course design). Based on the preferred learning styles of the majority of undergraduate students in this particular gross anatomy course, course activities can be hands on (i.e., active), grounded in concrete information (i.e., sensing), utilize visual representation such as images, figures, models, etc. (i.e., visual), and move in small incremental steps that build on each topic (i.e., sequential).

Teaching anatomy by dissection is under considerable pressure to evolve and/or even be eliminated, and curricular hours in the dissection laboratory are decreasing. As a possible means of easing this pressure, an online interactive anatomy program has been created to enhance the dissection experience, observational learning, and three-dimensional comprehension of human anatomy. An assessment was made of the utility of the program in preparing students for dissection laboratories and for examinations. The efficacy of the application was evaluated by first-year students and faculty with pre- and post-use surveys in anatomy courses at three medical schools. It was found that students felt better prepared if they utilized the Web site prior to their dissection laboratory, and faculty reported spending less time explaining basic concepts or techniques. It is concluded that a comprehensive online program significantly enhances the quality and efficiency of instruction in human anatomy in the dissection laboratory and could prove to be a useful tool at other institutions.
