Direct and indirect measures were used to compare the written language abilities of three groups of college students: two with learning disabilities and one without learning disabilities. Main effects were found for group, but not gender. Differences between nonlearning disabled students (NLD) and those with learning disabilities (LD) in writing were evident on both types of measures. Performance by LD students with disabilities in an area other than writing differed depending on the type of measure and often was no different from either of the other two groups. The combined use of direct and indirect measures appeared most effective for examining the complexities of writing produced by all groups. 相似文献
This study examines the changes in teaching practices during the implementation of a pedagogical model called the mathematics
reasoning approach (MRA), which was founded on 2 critical areas in mathematics, problem solving, and writing to learn. Three
algebra teachers implemented the approach with their classes, which were divided into control (traditional) and treatment
(student-centered approach) groups, with their levels of implementation measured by the Reformed Teaching Observation Protocol
(RTOP) instrument. The implementation of the model resulted in positive changes in teachers’ pedagogical practices and yet
showed the struggles they faced. In the control classes (traditional classes), the level of teaching remained the same throughout
the study, whereas in the treatment classes (MRA classes), a significant improvement in the level of teaching was observed.
Even though the teachers’ implementation levels differed from each other, the patterns of the change for all 3 teachers showed
similarities; that is, their MRA teaching level was initially equivalent to their control teaching, but as the semester progress,
there was a separation between the 2 approaches. This separation between the 2 approaches appeared to be dependent upon the
pedagogical area on which the teacher put emphasis. The skill of questioning seemed to be 1 which each teacher first changed. 相似文献
Two experiments were performed to determine the effect of sample duration (0.1, 2, and 4 sec), delay interval (.03, 4, 8, 16, and 32 sec), and type of stimulus (color and shape) on the matching performance of rhesus monkeys. In Experiment 1, the 15 possible delay-duration combinations were randomly presented in blocks of 15 trials. In Experiment 2, each duration was held constant and the five delays randomly presented. Then each delay interval was held constant with the three durations randomly varied. Matching performance increased as sample duration increased (ps < .01 and .005), while length of delay did not significantly affect performance. The type of stimuli paired in the matching test significantly affected performance (ps < .05 and .10) with the shape/shape choices leading to the poorest performance. Stimulus discriminability and amount of training with brief sample durations were implicated as significant determinants of matching performance. 相似文献
The management and utilization of collected data is crucial in evaluating programs and functional area effectiveness. Various assessment instruments may address similar functional areas of the college, yet we often fail to compile these data for comprehensive evaluation. The data collection matrix makes possible the integration of functional area data from numerous assessment sources and presentation of the information in a unified composite report. The matrix model will be discussed in relation to the various assessment instruments and the evaluation of functional areas and programs. This paper is directed toward institutional researchers who may wish to adapt the model to their own institution.Presented at the Annual Forum of the Association for Institutional Research, Louisville, KY, May 13–16, 1990. 相似文献
The purpose of this study was to investigate the role textbooks can play on writing complexity and lexical density as a proxy for critical thinking and ultimately learning, in relation to argumentative and summative writing when integrated with a virtual reality experience. In this study, differences in writing complexity and lexical density scores were measured across four different pedagogical modalities: VR alone, VR followed by textbook readings, textbook readings followed by VR, and textbook readings alone. Adult students, recruited from non-science-based higher education programs, responded to two prompts related to content found in the VR environments and discussed in the textbooks. The authors hypothesized that exposure to a virtual marine environment prior to responding to the writing prompts would enhance both argumentative and summative writing products, when compared to participants who only had access to the textbook experiences. Participants who were exposed to the VR environment then a textbook demonstrated significantly greater writing complexity and lexical density scores than those who had access to VR alone, or access to the text alone.
