Mastery learning, it is claimed, is among the most successful practices in higher education. Evidence supporting this claim has recently been criticized as empirically weak. This experiment employed a four-group, pre-post design to examine the learning consequences of a computer-administered mastery-testing approach in comparison with a seminar-discussion approach in a third-year university course. The mastery-testing approach generated significantly higher learning achievement than did the seminar-discussion approach. Replication and extension of this research approach are recommended to support generalizations across mastery-testing techniques, delivery systems, and disciplines.  相似文献

The authors are co-hosts of a popular open line radio show in Western Canada. In this article the term media counseling is explored and strategies in bringing expertise from the fields of Psychology and Psychiatry to the public are outlined. The authors have been convinced of the value of their approach, and outline purposes, as well as providing data relevant to this radio show That's Living.  相似文献

This study employs narrative methods to give a holistic view of the experiences of five mature age preservice teachers in a semester unit of science education. The unit was designed to help teachers examine and make explicit their ideas about science and science teaching and consider ways in which they might put those ideas into practice. The pivotal theme, around which the teachers' experiences could be organised, was found to be learning science. The preservice teachers expressed a need for a supportive learning environment in which concepts were built gradually and introduced using concrete examples. Previous science experience was found to be a major influence on the attitudes the participants brought to the present course. A lack of previous experience or negative past experiences were a major cause of anxiety. Gender was also important as it had limited the science experiences available to some participants in the past and continued to influence the way they participated in classes during the semester. Specializations: primary science, science teacher education, primary school field experience. Specializations: formation of teachers' knowledge, leadership, teacher change, school reform.  相似文献

This article examines the effect that postsecondary education has on earnings and the duration of time spent in the Social Security disability programs for young persons who are deaf or hard of hearing. Our hypothesis is that investments in postsecondary training increase the likelihood of employment for persons who are deaf or hard of hearing and thus reduce dependency on disability-related income support programs. A longitudinal data set based upon records from the National Technical Institute for the Deaf and Social Security administrative records is used for this analysis. We find that those who graduate, even those who graduate with vocational degrees, experience significant earnings benefits and reductions in the duration of time spent on federal disability programs when compared with those who do not graduate with a degree. This finding suggests that reductions in the duration of time spent on Social Security programs are not limited to those with the highest level of scholastic aptitude and that investments in post-secondary education can benefit a broad group of deaf and hard-of-hearing persons. In addition, the data show that individuals who attend college, but withdraw before graduation, fair no better economically than individuals who never attended college.  相似文献

This study examined the impact of computer simulation and supported science learning on a teacher’s understanding and conceptual knowledge of current electricity. Pre/Post tests were used to measure the teachers’ concept attainment. Overall, there was a significant and large knowledge difference effect from Pre to Post test. Two interesting interactions were observed during the data analysis. The first was the difference between Elementary and Secondary teachers. Both groups had significant gains, with large effect sizes, but the Elementary teachers (Pre-Mean = 3.70, Post-Mean = 7.51) started lower and ended higher exhibiting a significantly larger gain than the Secondary teachers (Pre-Mean = 4.96, Post-Mean = 6.71). The second interaction was the impact of gender. Both groups showed significant gains, with large effect sizes, but females (Pre-Mean = 3.90, Post-Mean = 7.21) gained significantly more than males (Pre-Mean = 5.13, Post-Mean = 7.01). These results confirm that computer simulation supported science learning can have a positive effect on concept attainment in teachers.  相似文献

Teacher self-efficacy refers to the beliefs teachers hold regarding their capability to bring about desired instructional outcomes and may be helpful for understanding and addressing critical issues such as teacher attrition and teacher use of research-supported practices. Educating students with autism likely presents teachers with some of the most significant instructional challenges. The self-efficacy of 35 special education teachers of students with autism between the ages of 3 to 9 years was evaluated. Teachers completed rating scales that represented self-efficacy and aspects of the following 3 of Bandura's 4 sources of self-efficacy: (1) sense of mastery, (2) social persuasions, and (3) physiological/affective states. Significant associations were observed between physiological/affective states and self-efficacy, but no associations were observed for the other sources.  相似文献

This paper describes the ways that students’ problem-solving behaviors evolve when solving multi-faceted, context-rich problems within a web-based learning environment. During the semester, groups of two or three students worked on five physics problems that required drawing on more than one concept and, hence, could not be readily solved with simple “plug-and-chug” strategies. The problems were presented to students in a data-rich, online problem-based learning environment that tracked which information items were selected by students as they attempted to solve the problem. The students also completed a variety of tasks, like entering an initial qualitative analysis of the problem into an online form. Students were not constrained to complete these tasks in any specific order. As they gained more experience in solving context-rich physics problems, student groups showed some progression towards expert-like behavior as they completed qualitative analysis earlier and were more selective in their perusal of informational resources. However, there was room for more improvement as approximately half of the groups still completed the qualitative analysis task towards the end of the problem-solving process rather than at the beginning of the task when it would have been most useful to their work.  相似文献
