Although there is a large body of research on the effectiveness of supplemental instruction for college undergraduates, very little of it has focused on transfer students, who often confront additional sources of stress and historically perform more poorly than their native student counterparts. In this study, we investigated the effectiveness of a peer-based supplemental instructional program in general and organic chemistry at a large state university over a six-year period, while considering differences across transfer and nontransfer students. The results suggest that the supplemental instruction improved outcomes overall but that nontransfer students benefit to a greater degree than transfer students, in the form of higher grades and pass rates, from attending supplemental instruction. The results suggest that peer-based supplemental instruction is a useful method to improve undergraduate student performance in chemistry, but more research is needed on ways to enhance the effectiveness of interventions in improving the performance of transfer undergraduate students in STEM fields. 相似文献

Within the UK, the "Long Term Athlete Development" (LTAD) model has been proposed by a variety of national governing bodies to offer a first step to considering the approach to talent development. The model, which is primarily a physiological perspective, presents an advancement of understanding of developing athletic potential alongside biological growth. It focuses on training to optimize performance longitudinally, and considers sensitive developmental periods known as "windows of opportunity". However, it appears that there are a number of problems with this theoretical model that are not necessarily transparent to coaches. Principally, the model is only one-dimensional, there is a lack of empirical evidence upon which the model is based, and interpretations of the model are restricted because the data on which it is based rely on questionable assumptions and erroneous methodologies. Fundamentally, this is a generic model rather than an individualized plan for athletes. It is crucial that the LTAD model is seen as a "work in progress" and the challenge, particularly for paediatric exercise scientists, is to question, test, and revise the model. It is unlikely that this can be accomplished using classical experimental research methodology but this should not deter practitioners from acquiring valid and reliable evidence. 相似文献

Genetics instruction in introductory biology is often confined to Mendelian genetics and avoids the complexities of variation in quantitative traits. Given the driving question “What determines variation in phenotype (Pv)? (Pv=Genotypic variation Gv + environmental variation Ev),” we developed a 4-wk unit for an inquiry-based laboratory course focused on the inheritance and expression of a quantitative trait in varying environments. We utilized Brassica rapa Fast Plants as a model organism to study variation in the phenotype anthocyanin pigment intensity. As an initial curriculum assessment, we used free word association to examine students’ cognitive structures before and after the unit and explanations in students’ final research posters with particular focus on variation (Pv = Gv + Ev). Comparison of pre- and postunit word frequency revealed a shift in words and a pattern of co-occurring concepts indicative of change in cognitive structure, with particular focus on “variation” as a proposed threshold concept and primary goal for students’ explanations. Given review of 53 posters, we found ∼50% of students capable of intermediate to high-level explanations combining both Gv and Ev influence on expression of anthocyanin intensity (Pv). While far from “plug and play,” this conceptually rich, inquiry-based unit holds promise for effective integration of quantitative and Mendelian genetics. 相似文献

This article examines the implications of shifting technology trends by looking at what we’ve lost or are losing, where we are, and where we need to go for making the needed transitions in knowledge and skills. Areas of growth within new media and the tech industry are good indicators of our growing interests in mobility, improved quality, and personalization, all happening within our increasingly global community. With the tremendous technological shifts, we need to consider the potential gaps or missing bits of knowledge slipping through the cracks. Then, determine where we need to go while forging ahead to provide the meaningful integration of new technologies through the selection of quality tools aligning to current best research based instructional practices to foster powerful, meaningful, engaged learning opportunities. 相似文献

This study examined customers' perceptions of personalized service communication performance in relation to their expectations as predictors of their satisfaction and loyalty intentions in four professional service contexts. Survey data were obtained from 253 customers regarding their expectations and experiences with physicians, dentists, auto mechanics, or hairdressers. Multisample covariance structure analysis procedures were performed to assess the level of support for alternative theoretical models across all four professional contexts. Results provided support for one model, specifying that customers' perceptions of communication performance accounted for significant variation in customer satisfaction, which, in turn, predicted customers' loyal behavioral intentions. Customers' expectations did not play an influential role in predicting customer satisfaction and loyalty, as proposed in an alternative model 相似文献

In two experiments, immediate feedback defined as feedback following the completion of a 40-item multiple-choice test and delayed feedback (received 48 hr later) were examined in a simulated classroom situation with college students. As defined, delayed feedback was not superior to immediate feedback, as would be predicted by the delayed retention effect. Also, feedback in the form of correct answer only was superior to correct answer plus distractors lending partial support to the frequency theory of recognition memory. In addition to not finding the delayed retention effect, an analysis of errors in experiment two did not support the interference—perseveration hypothesis as an explanation for the type of error committed following immediate feedback. 相似文献
