When students encounter a set of concepts (or terms or principles) that are similar in some way, they often confuse one with another. For instance, they might mistake one word for another word with a similar spelling (e.g., allusion instead of illusion) or choose the wrong strategy for a mathematics problem because it resembles a different kind of problem. By one proposition explored in this review, these kinds of errors occur more frequently when all exposures to one of the concepts are grouped together. For instance, in most middle school science texts, the questions in each assignment are devoted to the same concept, and this blocking of exposures ensures that students need not learn to distinguish between two similar concepts. In an alternative approach described in this review, exposures to each concept are interleaved with exposures to other concepts, so that a question on one concept is followed by a question on a different concept. In a number of experiments that have compared interleaving and blocking, interleaving produced better scores on final tests of learning. The evidence is limited, though, and ecologically valid studies are needed. Still, a prudent reading of the data suggests that at least a portion of the exposures should be interleaved. 相似文献

We evaluated 32 nonmedicated male adolescents diagnosed with attention-deficit/hyperactivity disorder (ADHD) in childhood, 35 male adolescents similarly diagnosed who were receiving methylphenidate (MPH), and 77 control boys. Both ADHD groups completed self-report questionnaires assessing sleep disturbances; weekday and holiday sleep duration; and symptoms of ADHD, anxiety, and depression. Parents and teachers rated the severity of the participants' ADHD. The control group completed self-report questionnaires assessing sleep disturbances. We found that nonmedicated participants and controls did not differ in the severity of sleep disturbance. In contrast, the medicated participants demonstrated a significantly greater severity of sleep disturbance compared with the nonmedicated participants and reported elevated levels of symptoms of ADHD, anxiety, and depression. Specific analyses showed that depressive symptoms contributed significantly to the degree of sleep disturbance when controlling for ADHD diagnosis and MPH treatment. These findings suggest that among adolescents with ADHD symptoms, the severity of symptoms of depression may contribute to the degree of sleep disturbance in addition to the effect of their primary disorder and MPH treatment. 相似文献

Abstract The purpose of this study was to investigate the effects of a competency-based approach to secondary student teaching in physical education. Secondary physical education student teachers (N = 7) were observed along with one class of students from each teacher's assignment during baseline and intervention conditions. Seven categories of teacher behavior and two categories of student behavior were observed with an interobserver reliability of 94%. Behaviors were observed by event and placheck recording procedures and were converted to rates per minute and percentages. These rates per minute and percentages were analyzed by behavior profiles and a multiple baseline design. Teacher behaviors included positive reactions to on-task behavior, negative reactions to off-task behavior, positive instructional feedback both general and specific, corrective instructional feedback both general and specific, and pupil contacts using the pupil's first name. The student behaviors included appropriate/inappropriate behavior and active/inactive behavior. Intervention consisted of a competency-based learning module, instructions, graphic feedback, cuing, reinforcement, weekly goals, and terminal goals. The module contained specific definitions of the behaviors, examples of when to emit the behaviors, baseline means for the behaviors, and a final, terminal goal for each behavior. Results indicated that the intervention strategy appeared to have a large positive effect on the following teacher behaviors: positive general feedback, positive specific feedback, specific corrective feedback, and the use of pupil's first names. Smaller increases occurred in the categories of positive reactions to on-task pupil behavior and general corrective feedback. A small decrease occurred in the negative reactions to off-task pupil behavior. Both categories of pupil behavior showed a small increase in the desired direction. Based on these results and the limits of the study, the data-based observation system combined with the competency-based format appeared to exert a measure of accountable control over the behavior of seven teachers and the behavior of their classes. 相似文献

This paper studies the optimal allocation of resources – in terms of school management, teachers, supporting employees and materials – in secondary schools. We use a flexible budget constrained output distance function model to estimate both technical and allocative efficiency scores for 448 Dutch secondary schools between 2002 and 2007. The results indicate that the average technical efficiency amounts to about 78 percent, implying that, with the given resources, schools could improve students’ educational performance by 28 percent. In terms of allocative efficiency, we estimate a 0.65 percent overutilization of teachers while management and supporting personnel are underutilized. The outcomes indicate that, despite the significant variation among schools, the average school is close to the optimal allocation of teachers. 相似文献

The concept of social networking, the focus of this article, targets the development of online communities in higher education, and in particular, as part of the admission process. A successful case study of a university is presented on how one university has used this tool to compete for students. A discussion including suggestions on how to enhance the success of this tool in your recruitment process is also provided. 相似文献

Abstract Cooperating teachers are often identified as some of the most important figures in the preparation of new teachers, and the reasons are not difficult to understand. Surprisingly, however, very little research has been conducted to quantify the effects of cooperating teachers on student teachers. This study examines the impact of student teachers' perceived interactions with their cooperating teachers and the influence that interaction has on student teachers' self‐efficacy for teaching. Results indicate a moderate correlation between perceptions of teaching efficacy and cooperating teacher‐student teacher interactions. Differences were found in the frequency of interaction based on the certification level of the student teacher, with elementary level student teachers perceiving a greater amount of interaction with their cooperating teachers. However, no differences based on certification level were detected in perceived efficacy. Student teachers' perceptions of the level of guidance offered by their cooperating teachers provided the most reliable predictor for their efficacy belief. 相似文献

Preparation of new teachers to work effectively in inclusion settings has not kept pace with demands created by recent reforms. General-education candidates typically receive limited exposure to inclusion strategies at the preservice level, and often their only meaningful preparation comes in the practicum setting. The purpose of this article was to examine the manner in which characteristics of cooperating teachers and the practicum settings affected efficacy for teaching students with disabilities. General-education student teachers responded to questionnaires about their collaboration with cooperating teachers, the focus on inclusion instruction in their practicum setting, and their efficacy for providing inclusion instruction. Results from a structural equation model indicated that efficacy is predicted both by focus and by collaboration with the cooperating teacher. Discussion focuses on implications for teacher preparation and directions for future research. 相似文献
