Among contemporary means of enhancing student learning, formative assessment is perhaps one of the most important and effective. While formative assessment ideas and practices have been shown to have a proven record enhancing student learning, these practices are slow to be fully integrated into teachers’ day-to-day classroom practices. This study describes a collaborative effort among university faculty and public school partners to train teachers in the skills and practices of formative assessment. Regarding teachers’ involvement in the formative assessment professional development, findings highlight that 1) teachers’ participation in the professional development efforts did strengthen their understanding of both general knowledge of formative assessment and the use of formative assessment practices, 2) teachers’ plans to use the strategies in the future were related to their understanding of these strategies, and 3) in-depth and comprehensive understanding of formative assessment practices were critical to concrete applications of such practices in their classrooms. With respect to the impact on student learning, an overall effect size of .41 was found for teachers who utilized a formative assessment strategy compared with district averages for similar learning objectives when the practices were not used. 相似文献

Changes in swimming technique during time to exhaustion at freely chosen and controlled stroke rates

Abstract The aim of this study was to assess technical changes during constrained swimming in time-to-exhaustion tests. Ten swimmers of national standard performed a maximal 400-m front crawl and two sets of exhaustion tests at 95%, 100%, and 110% of mean 400-m speed. In the first set (free), swimmers had to maintain their speeds until exhaustion and mean stroke rate was recorded for each test. In the second set (controlled), the same speed and individual corresponding stroke rate were imposed. The durations of the exhaustion tests, relative durations of the stroke phases, and arm coordination were analysed. For each speed in the “controlled” set, the exhaustion tests were shorter. Moreover, variables were consistent, suggesting a stabilization of stroke technique. Under the free condition, stroke rate increased to compensate for the decrease in stroke length. At the same time, swimmers reduced the relative duration of their non-propulsive phases in favour of the propulsive phases. Thus, swimmers changed their arm coordination, which came close to an opposition mode. These two constraints enable swimmers both to maintain their stroking characteristics and develop compensatory mechanisms to maintain speed. Moreover, stroke rate can be seen as a useful tool for controlling arm technique during paced exercise. 相似文献

Abstract To determine whether patterning instruction was as useful or more useful than other forms of instruction, kindergarten children (age five) were taught either patterning or early literacy or mathematics or social studies in matched sessions. Instruction was conducted in 15-minute sessions from November through mid-April. Posttests on patterning, mathematics, early literacy, and three executive functions showed that the children taught patterning became significantly better at patterning than those in the other instructional conditions. No differences were found between the children taught mathematics, early literacy, or social studies. Correlational analyses indicated that the relations of patterning ability, working memory, and inhibitory control to mathematics achievement were similar. Cognitive flexibility was not very strongly related to any other measure and the executive functions were relatively independent of each other for the children who were age five. 相似文献
