Whereas several studies investigated the effects of implementation of state-wide exit exams on student achievement, there is still little known about the impacts of the exams on students’ self-regulated learning. This paper examines the question as to whether the implementation of state-wide high school exit exams is associated with a change in the self-regulated learning of students in mathematics or English. We conducted a standardized questionnaire survey of students in two German states for a period of 3 years. In mathematics no significant effects of the immediate introduction of state-wide exit exams were identified. In English the results show significant positive and negative effects. The results are discussed and implications for further research are given.  相似文献

In this work a disposable, parallel microbioreactor (MBR) suitable for screening in batch or continuous mode is presented. The reactor consists of five parallel microchambers made of poly(dimethylsiloxane) bonded to a glass substrate. A grid structure is engraved on each chamber, allowing subsequent morphology imaging. Measurements are recorded over the entire cultivation period with constant parameters, namely, position and focus in the z-axis. The microdevice may be used for either parallel, uni- or multiparametric screening, and overcomes the drawback of gridless microwell plates which require expensive equipment such as an inverted microscope with an automatic stage. To validate the scalability from laboratory scale to microscale, and thus the cultivation protocol in the MBR, the germination of fungal spores (A. ochraceus) is evaluated for two different key magnitudes (pH and temperature) and compared to the results obtained from conventional laboratory scale systems (flasks and agar plates). Information on germination capacity with regard to interspecies' variability allows for optimization of industrial processes as optimal pH and temperature matched to the mesoscopic cultivation systems. The germination conditions therefore remain unaffected inside the MBR, while providing the following advantages: (i) dramatic reduction of medium consumption, (ii) submerged cultivation with constant oxygen supply, (iii) assured low cost and disposability, and (iv) possibility of a continuous cultivation mode.  相似文献

Improving children's attendance is a high priority for Head Start and other early childhood education programs serving low-income children. We conducted a randomized control trial in a major northern city to evaluate the impact of a low-cost intervention designed to promote parents' social capital as a potential influence on children's attendance in Head Start centers. The intervention assigned children to treatment group classrooms based on (a) neighborhood of residence (geography condition) or (b) the geography condition plus the opportunity for parents to form partnerships in support of their children's attendance, or to control group classrooms according to Head Start guidelines only. We did not find impacts on average attendance throughout the year. However, the intervention did lead to increased attendance during the winter when average center attendance was lowest. There were no impacts on fall or spring attendance. Follow-up exploratory analyses of focus groups with parents and staff suggested that parents' level of connection and trust, self-generated partnership strategies, and commitment to their children's education may be factors by which parents' social capital expands and children's attendance improves.  相似文献

The literature on vicarious traumatization has suggested that traumasensitive supervision may help to minimize the effects of vicarious exposure to trauma; however, nothing from the perspective of trauma counselors was noted. The present qualitative study involved 1 male and 8 female sexual violence counselors who had worked with sexual violence survivors from 1 to 9 years. The use of semistructured interviews and basic interpretive analysis revealed 4 themes: counselor feelings, vicarious traumatization, helpful qualities of supervision, and organizational considerations.  相似文献

Against the background of an adaptation of Cognitive Load Theory to learner-controlled settings we investigated the impact of learner characteristics on information utilization strategies, cognitive load, and learning outcomes in a hypermedia environment. Based on the data of 79 students, five clusters of students were identified according to their learner characteristics by means of a cluster analysis. Further analyses showed that learners with more favorable characteristics (i.e., higher prior knowledge, more complex epistemological beliefs, more positive attitudes towards mathematics, better cognitive and metacognitive strategy use) tended to show a more adaptive example utilization behavior, reported less cognitive load, and solved more problems correctly than learners with less favorable characteristics.  相似文献

To be successful, an instructional video presentation needs to be effective, valued, liked and efficient, and educationalists and designers should strive (explicitly and implicitly) to satisfy these criteria. In the interests of optimum teaching effect, a didactical distinction is recommended between video presentations that have to ‘instruct’, ‘explain’, ‘tell’ and ‘let encounter’. A schema or frame of reference is proposed, the use of which (it is claimed) can help to optimise communication between video producer, teacher and instructional designer  相似文献
