Changes in the profession of medicine are creating the demand for a substantive reexamination of current practices in medical education. Many of the major issues in addressing this challenge are structural and political rather than scientific; here we address one critical scientific issue that will be important to (though not by itself adequate for) guiding such changes. The factor we address is the development of a global performance assessment: a standardized mechanism to assess individual skills and abilities that can be used to evaluate alternative educational interventions. We discuss the issues involved in developing such a system, and describe a set of principles for defining desired outcomes and developing assessment tools, including (a) wide clinical scope, (b) direct relationship to actual clinical performance, (c) reliability and repeatability, and (d) non-longitudinal measurement. We discuss the role of simulation, reflective practice, and portfolios of work in developing such a system, and argue that whatever form such metrics take, a system of global performance assessment will develop from close collaboration between clinicians and educators with innovative ways of thinking about performance and expertise. 相似文献
ABSTRACT We compared cardiometabolic demand and post-exercise enjoyment between continuous walking (CW) and time- and intensity-matched interval walking (IW) in insufficiently active adults. Sixteen individuals (13 females and three males, age 25.3 ± 11.1 years) completed one CW and one IW session lasting 30 min in a randomised-counterbalanced design. For CW, participants walked at a mean intensity of 65–70% predicted maximum heart rate (HRmax). For IW, participants alternated between 3 min at 80% HRmax and 2 min at 50% HRmax. Expired gas was measured throughout each protocol. Participants rated post-exercise enjoyment following each protocol. Mean HR and V˙O2 showed small positive differences in IW vs. CW (2, 95%CL 0, 4 beat.min?1; d = 0.23, 95%CL 0.06, 0.41 and 1.4, 95%CL 1.2 ml.kg?1.min?1, d = 0.36, 95%CL 0.05, 0.65, respectively). There was a medium positive difference in overall kcal expenditure in IW vs. CW (25, 95%CL 7 kcal, d = 0.58, 95%CL 0.33, 0.82). Post-exercise enjoyment was moderately greater following IW vs. CW (9.1, 95%CL 1.4, 16.8 AU, d = 0.62, 95%CL 0.06, 0.90), with 75% of participants reporting IW as more enjoyable. Interval walking elicits meaningfully greater energy expenditure and is more enjoyable than CW in insufficiently active, healthy adults. 相似文献
The goal of this study was to investigate the timing of online homework completion and its effects on student performance. Data was collected from two large, first-semester general chemistry sections at a southwestern university. Specifically, this study aims to explore the link between when students complete their homework relative to the date the material was covered in lecture and student performance in that class. Topics covered in the study included VSEPR, Lewis structures, and molecular geometry. Performance was measured by different variables, namely in-class clicker scores (short-term) and exam grade (long-term). Students were divided into three groups: students who completed the relevant homework within 2 days after the lecture (before the next lecture), those who completed the homework 2 to 4 days after the lecture, and students who completed the homework more than 4 days after the material was covered in lecture. The study also took into consideration student reasoning abilities, as measured by the Test of Logical Thinking (TOLT), with a focus on at-risk students (low TOLT students). Results showed promising findings for low TOLT students. Instructors can employ results from this study to help their students better utilize the online homework resources.
A sample of 100 students from junior high school physical science, high school chemistry, and introductory college chemistry were examined for understanding of five chemistry concepts. The concepts addressed were chemical change, dissolution of a solid in water, conservation of atoms, periodicity, and phase change. The amount of experience with the concepts (grade level) and reasoning ability (developmental level) were examined as possible sources of variation in student understanding. Differences in understanding with respect to grade level were found to be significant for the concepts of chemical change, dissolution of a solid, conservation of atoms, and periodicity. However, few of the students in the college chemistry sample exhibited sound understanding of chemical change, periodicity, or phase change. The use of particulate terms (atoms, ions, molecules) increased across the grade levels. Reasoning ability proved to be a significant factor for student understanding of conservation of atoms and periodicity. An examination of the number and types of misconceptions across the grade levels revealed several interesting patterns and suggested sources for the students' alternative conceptions. 相似文献

ABSTRACTResearch Findings: The current study examined characteristics of 71 Early Head Start lead teachers in relation to classroom interactions with infants and toddlers. Measured teacher characteristics included education, years of experience, beliefs about child rearing, depressive symptoms, and the temperamental characteristics of positivity and frustration. Teacher–child interactions were measured using the Classroom Assessment Scoring System, Toddler Version (La Paro, Hamre, & Pianta, 2012). Results indicated that field of degree was directly associated with the majority of dimensions of teacher–child interactions. Examination of teachers’ years of experience and intrapersonal characteristics revealed a number of significant interactions, indicating that teacher experience and appropriate beliefs may serve as protective factors in the presence of psychosocial risk factors. Practice or Policy: Overall, our findings suggest that both early childhood education degrees and years of experience are directly or indirectly associated with multiple dimensions of teacher–child interactions, confirming that these patterns established for preschool teachers hold for teachers of infants and toddlers. These results also suggest that years of experience and progressive beliefs about children may be especially important for teachers who are depressed or who have low levels of positivity and high levels of frustration. Implications for future research, as well as preservice and in-service professional development, are discussed. 相似文献
