This study examined whether the criteria for mastering unit quizzes in a mastery-oriented course should increase, decrease, or remain fixed across units. Subjects were randomly assigned to one of three treatments, one in which mastery criteria on unit quizzes gradually increased, a second in which mastery criteria gradually decreased, and a third in which mastery criteria remained fixed. Results indicated that students in the fixed criterion condition proceeded through the course at the steadiest pace and performed better than the other students on the unit quizzes they mastered. In addition, the vast majority of subjects indicated that they preferred the fixed criterion condition. These results strengthen the notion that the level of performance expected of students in a mastery-oriented course should not vary across units.  相似文献

This paper gives a synopsis of an extensive programme of case studies on real uses of computer-assisted learning (CAL) materials within UK engineering degree programmes. The programme was conducted between 2000 and 2003 and followed a questionnaire-based survey looking at CAL use in the UK and in Australia. The synopsis reveals a number of key messages for academic tutors and authors including students' enthusiasm for notes, self-tests and features to aid visualisation. Publishers should also consider pricing and licensing arrangements suited to the individual user. Cet article donne une synthèse exhaustive des études de cas concernant l'utilisation concrète des logiciels d'enseignement assisté par ordinateur (EAO) dans les études d'ingénieur au Royaume Uni. Ces études, conduites entre 2000 et 2003, sont basées sur l'analyse de questionnaires concernant l'utilisation de l'EAO au Royaume Uni et en Australie. La synthèse révèle un certain nombre de points clés destinés au corps enseignant et aux auteurs, dont notamment l'intérêt des étudiants pour les cours papiers, les exercices d'autoévaluation et les éléments d'aide à la visualisation. Les aspects liés aux coû ts et aux droits d'auteurs devraient aussi ûtre pris en compte par les éditeurs, afin de faciliter l'accès aux logiciels par les utilisateurs individuels.  相似文献

Over the years neoliberal ideology and discourse have become intricately connected to making science people. Science educators work within a complicated paradox where they are obligated to meet neoliberal demands that reinscribe dominant, hegemonic assumptions for producing a scientific workforce. Whether it is the discourse of school science, processes of being a scientist, or definitions of science particular subjects are made intelligible as others are made unintelligible. This paper resides within the messy entanglements of feminist poststructural and new materialist perspectives to provoke spaces where science educators might enact ethicopolitical hesitations. By turning to and living in theory, the un/making of certain kinds of science people reveals material effects and affects. Practicing ethicopolitical hesitations prompt science educators to consider beginning their work from ontological assumptions that begin with abundance rather than lack.  相似文献

To meet recent accountability mandates, school districts are implementing assessment frameworks to document teachers’ effectiveness. Observational assessments play a key role in this process, albeit without compelling evidence of their psychometric rigor. Using a sample of kindergarten teachers, we employed Generalizability theory to investigate (across teachers, raters, and lessons) the stability of scores obtained with two different observation measures: The CLASS K-3 and the FFT. We conducted a series of Decision studies to document (for both measures’ constituent domains) the number of lessons per teacher and raters per lesson that would justify the use of observation scores for high stakes decisions. Acceptable, stable scores for individual-level decisions about teachers may generally require more raters and lessons than is typically used in practice (1–2 raters and fewer than 3 lessons). The considerable variability of observation-based scores raises concerns about either measure’s appropriateness for making individual or group decisions about teachers’ effectiveness.  相似文献

The present study was concerned with the prediction of first year grade point averages of associate degree nursing students. The primary objective of this investigation was to determine whether the inclusion of quadratic and/or interaction terms in a regression model would improve the prediction of student nurses' grade averages. The predictor battery included cognitive, biographical, and personality variables. Results indicated that interaction and quadratic terms improve both the predictability of grade point averages and the replicability of these predictions. The inclusion of higher order terms in prediction research is suggested as a means of improving predictive efficiency.  相似文献
