Reform efforts have emphasized the need to support teachers' learning about reform‐oriented practices. Educative curriculum materials are one potential vehicle for promoting teacher learning about these practices. Educative curriculum materials include supports that are intended to promote both student and teacher learning. However, little is known about the extent to which existing curriculum materials provide support for teachers and the ways they can be improved. In this study, eight sets of high school biology curriculum materials were reviewed to determine their potential for promoting teacher learning. Design heuristics for educative curriculum materials were adapted for use as evaluation criteria. From this analysis, several themes emerged. First, the materials tended to provide support for teachers' subject matter knowledge and pedagogical content knowledge for students' ideas (e.g., misconceptions) but rarely for their pedagogical content knowledge of scientific inquiry. Second, the materials contained several implementation guidance supports but far fewer rationales for instructional decisions, which are an important feature of educative curriculum materials. Finally, the quality of support varied widely, differing in its degree of relevance, pedagogical helpfulness, and depth. The article concludes with recommendations for the redesign of existing curriculum materials. © 2009 Wiley Periodicals, Inc. J Res Sci Teach 46: 977–998, 2009 相似文献

Deaf and hearing college students' mean reaction times (RTs) were compared on a mental calculation task in which they had to verify the accuracy of solutions to addition and multiplication problems. The deaf students were divided into higher and lower readers. Higher deaf readers and hearing students had similar RTs and accuracy on addition problems; their RTs were greater in the voicing interference mode than in the manual tapping interference mode. The lower deaf readers showed no RT differences between the two interference modes and had consistently lower RT performance and score accuracy across the verification tasks. On the verification task for multiplication problems, all participants showed a greater RT effect for manual tapping. The lower deaf readers were significantly less accurate on multiplication problems. 相似文献

In this study of deaf college students' performance solving compare word problems, relational statements were either consistent or inconsistent with the arithmetic operation required for the solutions. The results support the consistency hypothesis Lewis and Mayer (1987) proposed based on research with hearing students. That is, deaf students were more likely to miscomprehend a relational statement and commit a reversal error when the required arithmetic operation was inconsistent with the statement's relational term (e.g., having to add when the relational term was less than). Also, the reversal error effect with inconsistent word problems was magnified when the relational statement was a marked term (e.g., a negative adjective such as less than) rather than an unmarked term (e.g., a positive adjective such as more than). Reading ability levels of deaf students influenced their performance in a number of ways. As predicted, there was a decrease in goal-monitoring errors, multiple errors, and the number of problems left blank as the reading levels of students increased. Contrary to expectations, higher reading skills did not affect the frequency of reversal errors. 相似文献

High turnover and short tenures are the norm for state university presidents in the last part of the twentieth century. Depending on the type of institution, the average state university president stays in office about four years, some three years shorter than the national average of seven years for all higher education institutions. The article discusses this trend and relates length of tenure to the formal and informal evaluations of presidents. Beginning with a presentation of presidential tenure (time in office) data and a discussion of the benefits of longer terms, the article continues with a dialogue on the role of the president in state institutions of higher education. It is argued that the position of president necessitates constituent leadership with presidents often expected to please all constituencies. Included in this discussion are the nature, role, and effectiveness of evaluations of university presidents. The authors conclude that evaluations of presidents make little difference in decisions to retain or remove presidents. Even a good or great evaluation does not offset the impact of the unforseen event or changes in political leadership within a state or on a board. The authors agree that annual reviews or reports are valuable in improving a presidents performance and leadership. Evaluations make a difference when they are supervised by individuals with direct knowledge of the job, are fair in terms of expectations from often divergent constituent groups, and focus on maximizing the ability of the president to improve the institution. 相似文献

Research in the United States suggests that teachers view Black students' misbehavior as more likely to reoccur, but such research has not disentangled the effect of race from related factors. We used conjoint analysis to experimentally test the effect of multiple student characteristics on the chances of being referred for a behavior intervention program. Although preservice teacher participants were not more likely to refer Black students, they were more likely to refer students who had lower grades, lived in poverty, lived with a single mother, and had been retained. We interpret these results and highlight directions for future research and practice. 相似文献

This study was designed to determine the predictive validity of selected admissions variables used by the University of Kentucky College of Medicine. Data for the study were collected from 586 students admitted to the M.D. program from 1961 to 1968. These students were categorized into one of three groups (Successful [SUCC], Successful with Extended Study [SWES], and Lost to Medicine [LTM]) based upon their performance in medical school. A two-way analysis of variance and the use of a post hoc Scheffé method of multiple comparisons indicated significant differences between the SUCC group and the combined SWES and LTM groups. Therefore, the data revealed the predictive ability of two admissions variables and suggested the need for additional research into the subjective variables used in the admissions process. 相似文献

The goals of today's school athletic programs are vastly different from the original intentions of the administrators who established the first interscholastic athletic teams. For athletics to be anything more than a drain on school and taxpayer resources, these programs must undergo serious changes. 相似文献
