Despite the apparent lack of universally accepted goals or objectives for elementary science methods courses, teacher educators nationally are autonomously designing these classes to prepare prospective teachers to teach science. It is unclear, however, whether science methods courses are preparing teachers to teach science effectively or to implement the National Science Education Standards (National Research Council, 1996). Using the Science Teaching Standards as a framework for analysis, this research proceeded in two phases. During the first phase, the elementary science methods courses, perspectives, and practices of six science teacher educators were examined to determine similarities and differences in the course goals and objectives, overall emphases, and their efforts to prepare their students to implement the Science Teaching Standards. The second phase of the study investigated the elementary science methods courses of a national sample of science teacher educators as reflected in their course syllabi. It was found that universal inclusion of content related to the Science Teaching Standards does not exist, nor are there clear linkages between course goals, activities, and assignments.  相似文献

A sample of elementary school- and high school-age deaf students in special education programs in the Australian state of Queensland using Australasian Signed English (ASE) took the Test of Syntactic Abilities (Quigley, Steinkamp, Power, & Jones, 1978) and wrote a story in response to a wordless picture sequence. Several analyses of the students' test scores and of the written language of their stories were undertaken. It was found that classroom use of ASE was of benefit to these students in developing English and telling a story in writing, but that there were complex aspects of syntax that required special teaching. The implications for the use of Signed English systems and the teaching of English to deaf students who use Signed English communication are examined.  相似文献

Attention-deficit/hyperactivity disorder (ADHD) was previously believed to be a disorder of childhood, with symptoms attenuating at the onset of puberty. Follow-up studies, however, suggest that the majority of children with ADHD continue to manifest symptoms into adulthood. Although the inattention components associated with ADHD persist into adulthood, the nature of the hyperactivity component is less well understood. For example, according to criteria established by the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, hyperactivity in adolescents and adults may be limited to subjective feelings of restlessness. Recent studies with adults with ADHD have also reported that mental restlessness is commonly reported by individuals with the disorder. To better understand this characteristic of ADHD, the Internal Restlessness Scale (IRS) was developed. The results of the IRS suggest that (a) college students with ADHD report significantly higher ratings of internal restlessness than college students without ADHD, and (b) the IRS appears to have adequate test-retest reliability and a four-factor structure. Implications and suggestions for future research are discussed.  相似文献

A comparison of the performance of two groups of third-grade students practicing division problems is used to assess the effect of a commercial computer-assisted instruction (CAI) drill program on learning. The progress of the experimental group, who used the computer drill program, is compared with a similar group of students using a conventional print drill method. The data demonstrate that after five weeks of practice, no significant differences existed in the achievement level of either the experimental group or the control group. The findings further suggest that use of computer drill materials may be no more effective than print drill materials for assisting third-grade students to achieve proficiency level in learning division of whole numbers.  相似文献

The authors examined the social practices and outcomes of 23 immigrant and 16 nonimmigrant preschoolers in English only preschool classrooms. In both classrooms, the majority of the children (nearly two thirds) were immigrant, English language learners. The children's social attempts, social strategies, speech functions, and degree of social success were observed and comparisons were made between nonimmigrant and immigrant peers. There were similarities between groups in their social engagement and social construction strategies; there were differences in social roles, social language functions, and types of social construction strategies. There also were significant differences in the social success of the two groups. Immigrant children experienced rejection of their social bids more than their preschool peers did. Immigrant children also were less likely to be leaders and seemed positioned in a lower social status among their peers did. These results are discussed along with implications for educational practices.  相似文献

The purpose of this study was to determine the effects of sequences of the trunk and arm angular motions on the performance of javelin throwing. In this study, 32 male and 30 female elite javelin throwers participated and were separated into a short official distance group or a long official distance group in each gender. Three-dimensional coordinates of 21 body landmarks and 3 marks on the javelin in the best trial were collected for each subject. Joint center linear velocities and selected trunk and arm segment and joint angles and angular velocities were calculated. The times of the initiations of the selected segment and joint angular motions and maximum angular velocities were determined. The sequences of the initiations of the selected segment and joint angular motions and maximum angular velocities were compared between short and long official distance groups and between genders. The results demonstrated that short and long official distance groups employed similar sequences of the trunk and arm motions. Male and female javelin throwers employed different sequences of the trunk and arm motions. The sequences of the trunk and arm motions were different from those of the maximal joint center linear velocities.  相似文献

The present series of five flavor aversion experiments with rat subjects examined compound conditioning at varying CS-US intervals. Using a taste-taste design, Experiments 1A and 1B demonstrated overshadowing at a 0-min CS-US interval and potentiation at a 120-min CS-US interval, and these effects occurred with both tastes of the compound. Experiment 2 showed that the aversion to a single element is reduced when the CS-US interval is increased to 120 min, but the aversion for a compound taste is not. Experiments 3A and 3B explored odor + taste compound conditioning; the results demonstrated odor potentiation across the trace interval and a transition from taste overshadowing to taste potentiation. Collectively, the data show that the change from overshadowing to potentiation was not due to changes in the aversions produced by compound conditioning but, instead, was due to a more rapid loss of conditionability across a trace interval prior to the US in single-element conditioning. These experiments suggest that following compound conditioning, the aversion to each element represents generalization decrement from the configured compound, but the designation of overshadowing or potentiation actually depends on the status of conditioning in the single-element control.  相似文献

Anti-racist efforts require talking with children about race. The present work tested the predictors of U.S. adults' (N = 441; 52% female; 32% BIPOC participants; Mage = 35 years) conversations about race with children across two timepoints in 2019. Approximately 60% of adult participants talked to their children (3–12 years) about race during the preceding week; only 29% talked to other adults about race during the same period. This paper describes the content and predictors of conversations about race, revealing how conversations differ depending on the participant's race, a child's age, and whether the conversation occurs with children or another adult. These data have important implications for theorizing about when, why, and how adults actually talk about race with children and adults.  相似文献

Understanding the interaction between internally constructed and externally imposed aspects of the teaching context may be the missing link between calls for school reform and teachers' interpretation and implementation of that reform. Although the context of the local school culture has a profound impact on teachers, there are other external forces that are specifically aimed at influencing teachers' pedagogical and curricular decisions. These externally imposed aspects of context include some of the existing tools of reform, such as national standards, mandated state core curricula, and related criterion‐referenced testing. However, little is known about how these reform tools impact teachers' thinking about science and science teaching or how teachers respond to such tools. This study examined the interactions between individual teachers' beliefs about teaching and learning science in elementary school and the tools of reform that are imposed upon them. Comparative case studies were conducted in which two elementary teachers' science instruction, teaching context, and related beliefs were examined, described, and analyzed. In this study, the teachers' fundamental beliefs about science and what it means to teach and learn science influenced their interpretations of the sometimes contradictory messages of reform as they are represented in the standards, mandated curriculum, and end‐of‐level tests. Suggestions about what these findings mean for needed aspects of teacher professional development are offered. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 44: 396–423, 2007  相似文献
