This article describes the evaluation of a simplified version of the new software evaluation model proposed by Reiser and Dick (1990). This approach to evaluation of instructional software focuses upon the collection of performance data to determine the extent to which students learn the skills the software is designed to teach. In two field evaluations of instructional software packages, it was found that use of the simplified software evaluation model generally produced evaluative conclusions similar to those reached using the original, more complex model. It was also found that student learning data did not support the high ratings assigned by subjective software evaluation services. These findings support the use of the simplified model by teachers and media specialists who have limited time and resources, and stress the need for local on-site evaluation efforts. 相似文献

The effects of changeover delays of fixed or variable duration on concurrent variable-interval performance in pigeons were investigated in a series of three experiments. Experiment 1 compared the effects of a fixed, variable, or variable signaled changeover delay on interchangeover times and responding during and after the changeover delay. The duration of the changeover delays was systematically varied in Experiment 2, and the relative reinforcement frequencies were manipulated in Experiment 3. Interchangeover times were found to be shorter when changeover delays of variable duration were compared with those of fixed duration. Changeover delays of fixed duration produced higher response rates during the changeover delay than after the changeover delay had elapsed; changeover delays of variable duration produced such differences to a lesser extent. It was concluded that the changeover delay in concurrent variable-interval schedules of reinforcement functionally acts as a delay period to the next opportunity for reinforcement, possibly serving as a conditioned reinforcer for the behavior preceding it (the interchangeover time) and as a discriminative stimulus for the behavior in its presence (response rates during the delay). 相似文献

One of the goals of current education is to ensure that graduates can act as independent lifelong learners. Graduates need to be able to assess their own learning and interpret assessment results. The central question in this article is how to acquire sustainable assessment skills, enabling students to assess their performance and learning throughout life, and preparing them to meet their own future learning needs. This article presents an integrated model for developing sustainable assessment skills, consisting of three components: conditions necessary for the development of sustainable assessment skills, elements of sustainable assessment and instructional methods for guiding students in the development of sustainable assessment skills. The article concludes with suggestions for future research to further develop the proposed model. 相似文献

In flipped-class pedagogy, students prepare themselves at home before lectures, often by watching short video clips of the course contents. The aim of this study was to investigate the effects of flipped classes on motivation and learning strategies in higher education using a controlled, pre- and posttest approach. The same students were followed in a traditional course and in a course in which flipped classes were substituted for part of the traditional lectures. On the basis of the validated Motivated Strategies for Learning Questionnaire (MSLQ), we found that flipped-class pedagogy enhanced the MSLQ components critical thinking, task value, and peer learning. However, the effects of flipped classes were not long-lasting. We therefore propose repeated use of flipped classes in a curriculum to make effects on metacognition and collaborative-learning strategies sustainable. 相似文献

In this paper I discuss two weaknesses in Bourdieu’s work on cultural capital, both of which are related to his integration of the multidimensional nature of social space in different domains of life: social mobility, lifestyle differentiation, and political orientation. First, there is an anomaly between the work on social mobility and on lifestyles. Multiple dimensions of social origin (cultural and economic capital) are related to uni‐dimensional outcomes (e.g. schooling levels), whereas it would be more appropriate to study multidimensional schooling outcomes too. Secondly, although Bourdieu sees a close resemblance in the type of resources affecting lifestyle preferences and political orientations, I argue that these outcomes are affected by two different types of resources: cultural and communicative resources. Proposals for progress, including a review of the empirical results supporting these, are given. 相似文献
