This paper describes MultiTool, a new programming shell for use in developing multi-media education and training applications with microcomputer-based software and videodisk-based images. This system was generalized from a prototype system that was developed for teaching construction equipment and methods. MultiTool enables other users to develop their own education and training applications. It provides a variety of standard development options that perform distinctly different functions. It also includes libraries of graphic designs, function buttons, interface elements and video drivers. The potential impact of this program resides in improving the quality and productivity of training and education in engineering, science and other fields 相似文献

To assess the impact of a college preparation program, district-wide changes in high-stakes test pass rates are examined, followed by an examination of specific program elements that are associated with students’ score changes. Changes in pass rates for districts with and without services are compared for the Latina/o and overall student populations. This study also examines the relationship between hours of participation in various elements of the college preparation program and changes in test scores of low-income Latina/o students. Results indicate that key program elements related to improvements in test scores include participation in mentoring and summer programs. 相似文献

Mentoring can be used as a pedagogical alternative both to extend and augment the educational experience of business students. This article addresses a gap in the literature regarding the use and effectiveness of mentoring in undergraduate business education by examining improvements to an existing mentoring program. After reviewing the mentoring literature and identifying four critical elements for program success (matching, preparation, interaction and outcome assessment), the researchers used a cohort design and developed a survey to assess baseline participant satisfaction with these elements. Interventions were developed to enhance the mentoring program, and a second cohort allowed the authors to assess the benefits of these interventions. With statistically significant improvements in two out of four program elements (and a third showing marginally significant differences), the results demonstrate that the authors’ approach to evaluating and enhancing mentoring program effectiveness is useful in business education. 相似文献

We report on the development of an after-school and summer-based science, technology, engineering, and mathematics curriculum infused with the arts and social emotional learning content (STEAM SEL). Its design was motivated by theory and research that suggest that STEM education is well-suited for teaching empathy and other emotion-related skills. In this paper, we describe the activities associated with the development and design of the program and the curriculum. We provide expert-ratings of the STEAM and social emotional elements of the program and present instructor and participant feedback about the program’s content and its delivery. Our results revealed that infusing the arts and social emotional learning content into science education created a holistic STEM-related curriculum that holds potential for enhancing young children’s interest in and appreciation for science and its applications. The data also suggested that the program was well-developed and, generally well-executed. However, experts rated the STEAM elements of the program more positively than the SEL elements, especially with regard to sequencing of lessons and integration among the lessons and hands-on activities, indicating that program revisions are warranted. 相似文献

The use of aggregated student evaluations of their courses and course elements (e.g., subject functionality, affect, difficulty, graded assignments) is suggested as an efficient and useful means of obtaining program and department assessments. Given that the instruments used to collect student evaluations are valid (if they are not, they should not be used for any purpose), then averaging class data is likely to provide a valid and reliable index of program and department effectiveness as evaluated by students.Program and department assessment data are presented and discussed for a large northeastern professional school. Large and significant differences in the ratings of program elements were found. Although many of the elements designed into the program by the administration and faculty were perceived as operational by the students, some discrepancies between the design and student perceptions existed. Substantial departmental differences were also found which indicated areas of strength and weakness both within and across departments. The potential usefulness of the assessment for internal change and development is discussed. 相似文献
