We determined if the “relative age” effect, wherein older students in an age cohort in early grades do better academically, extends to birthdates of applicants to medical schools, and if birthdates are related to the success of their applications. We examined birthdays of applicants from Michigan to Wayne State University’s School of Medicine, relative to December 1, the cut‐off date for eligibility to enter kindergarten in Michigan. Significantly fewer applicants ≤22 years of age were born in the three‐month period (September, October, November) immediately preceding the December 1 cut‐off date, but there was no statistically significant difference in the probability of their acceptance. We conclude that delayed entry to kindergarten influences applications for medical school acceptance, but does not affect the success of their applications. 相似文献

In Experiment 1, three groups of rats were trained on one of three serial patterns consisting of different numbers of .045-g food pellets, either the simple strong monotonie pattern 14-7-3-1-0 (Group SM) or one of two complex weak monotonie patterns, 14-5-5-1-0 (Group 5-5) or 14-9-1-1-0 (Group 1-1). Learning to anticipate the terminal 0-pellet element occurred faster in Group 1-1 than in Group SM, which in turn learned faster than Group 5-5. In Experiment 2, Groups SM, 5-5, and 1-1 were trained on the first four elements of the patterns experienced by their Experiment 1 counterparts and then were tested for their ability to extrapolate the series to include the addition of a 0-pellet element in the fifth position. Extrapolation behavior was better in Group 1-1 than in Group SM, which in turn performed better than Group 5-5. The results were shown to be consistent with a memory-discrimination model of serial learning and inconsistent with a rule-learning model based on pattern complexity. 相似文献

This paper reports the findings of a study which aimed to elicit teachers' perceptions of pupils' challenging behaviour. Teachers were asked to indicate: which aspects of challenging behaviour concerned them; their responses to it; which strategies they found effective; what they believed to be the causes of it; how stressed they felt; and how effective they felt when dealing with it. They were also asked to identify sources of information, advice and help and to rate different types of challenging behaviour in terms of severity of challenge. Results indicate that teachers are concerned about challenging behaviour and find it stressful. Whilst considering themselves to be effective in dealing with it, a proportion report feeling frustrated by it, angry, upset and/or at a loss. The most frequently cited challenging behaviour was aggression, although self-injury was found to be the most challenging. Whilst recognising the communicative basis of many forms of challenging behaviour teachers nevertheless tended to select strategies which were concerned with diffusion rather than prevention. The most likely source of information, advice and help was other teachers. Some differences in responses were noted according to experience and whether or not additional qualifications were held. 相似文献

The aim of this research was to examine the use of a rapid application development (RAD) approach in improving the usability
(effectiveness, efficiency, and appeal) of instructional materials for preservice teachers. The RAD approach used was the
analysis, synthesis, evaluation and change (ASEC) model (Reigeluth & Nelson, 1997). After examining existing materials, 11
units of instruction were prototyped, tested, modified, and retested with the requisite changes being implemented over the
course of three semesters. Qualitative and quantitative data were collected from 570 students, 7 instructional designers,
and 4 lab assistants. Results of the study showed significant increases in usability scores between the second and third semester.
Both positive and negative experiences in using a rapid development model are discussed. 相似文献

In this study, we worked with second-year engineering students at an Australian university to examine previously identified threshold concepts within the theoretical framework of Possible Selves. Using workshops as the context for intensive work with students, students were encouraged to consider their future lives and work, including their engineering fears, expectations, and aspirations. The findings revealed many students to have a poor understanding of the realities of engineering work. Moreover, perceived gaps between self-efficacy and the requirements of engineering work appeared to be motivating if students deemed it possible to reduce the gap, but demotivating if they identified a characteristic over which there was perceived to be no control. The study suggests that these engineering students needed more opportunities to explore both the roles of engineers and their own possible selves. Overall, the findings indicate that higher education students may need encouragement and support to explore potential future roles, and they strengthen calls for further research in this area. 相似文献

The purpose of this article is to suggest principles for embedding support in instruction to facilitate self-regulation (SR)
in less expert learners. The principles are based on an analysis of the growing body of research on the distinctive self-regulation
differences between higher and lower achieving learners. The analysis revealed four instructional principles that designers
should consider to provide support for self-regulation. Each principle is supported by research and instructional examples
are included. 相似文献

The paper gives a brief overview of the use of digital video in distance education, the background to The Open University's Digital Video Applications (DiVA) Project, the contexts in which the Digital Video Library system is being used and some evaluation findings. Through DiVA, the university is investigating how it can use its video assets effectively, to support reuse of existing materials in course production. The project team is also evaluating student use of the system. The paper reports on an observation study which revealed several usability issues and stakeholders' opinions about potential uses of the DiVA system. This is followed by findings from an evaluation of student use of the system at a residential school and its use as part of an online learning activity undertaken by students accessing the system remotely. Evaluation findings to date indicate some quality and workload issues but they also show opportunities that come to light when using the DiVA system. 相似文献

As a teaching tool, the World Wide Web (WWW) is unprecedented in its ability to transmit information and enhance communication between scientist and student. Just beginning to be developed are sites that actively engage the user in the learning process and provide hands-on methods of teaching contemporary topics. These topics are often not found in the classroom due to the complexity and expense of the laboratory equipment and the WWW is an ideal tool for overcoming this difficulty. This paper presents a model for using the Internet to teach high school students about plasma physics and fusion energy. Students are given access to real-time data, virtual experiments, and communication with professional scientists via email. Preliminary data indicate that student collaboration and student-led learning is encouraged when using the site in the classroom. Scientist/student mentoring is enhanced with this form of communication. 相似文献

Guided by the Theory of Racial Socialization in Action (TRSA; Smith-Bynum in press), this study examined observed caregiver-provided ethnic-racial socialization in response to a school-based discriminatory dilemma. Forty-five Black and 36 Latinx caregivers (88% mothers) with low-income and their children (Mage = 11.09, SD = 0.29; 46.3% female) participated in Dallas, Texas from 2018 to 2019. Dyads responded to a hypothetical scenario in which a school counselor makes a discriminatory comment to the child. Results of a factor mixture analysis suggested that caregivers engaged in the dialogue using one of four approaches: Low-engaged, Legacy, Racial Literacy, or High-engaged. Profiles were found to differ significantly by the race/ethnicity and language of caregivers and were associated with youth’s concurrent behavioral engagement (R2 = .04). 相似文献
