The University of Hawaii at Hilo began offering a B.S. degree in computer science via distance education in 1998. This program serves students on islands with no four-year educational institution.The experiences in planning for and teaching such a program are discussed, together with the technologies used and the outcomes to date. 相似文献

The purpose of this investigation is to examine some solutions to the problems involved in the learning and teaching of biological inheritance and the evolution of living beings at the secondary school level. For this, we implemented a teaching programme which takes into account a constructivist approach to learning and analysed the progress in students' knowledge at different times (pre-test, post-test and retention test). Qualitative and quantitative analysis of the results show that the programme instilled a knowledge close to what might be considered adequate for this educational level. As a follow up, we propose certain disciplinary criteria for selecting and sequencing the content to be taught and discuss the educational circumstances which favour the construction of student knowledge on these topics. 相似文献

Abstract This report investigates mentoring from the perspectives of 7 experienced secondary public school teachers from four different school districts in Oklahoma. The participants' teaching experience ranged from 10 to 30years. The author reviewed the research process and data provided through the teachers' interviews and protocol writings to further explain the nature of mentoring and the benefits of mentoring experienced teachers. The experienced teachers benefited from the mentoring process and their mentoring experiences in two important areas. At the professional level, the teachers gained a sense of self as professional educators. At the personal level, these teachers identified mentoring as a process that worked in almost any situation; in addition, they recognized that conversing about concerns with a knowledgeable colleague was a workable solution for solving issues. 相似文献

Abstract Correspondence study represents the first and most persistent distance education format in American universities. Later called independent study, it enabled universities to disseminate instruction far beyond their campuses. Yet, national‐level leadership provided by the National University Continuing Education Association (NUEA) and its divisions has been relatively restrained. In contrast, leadership in the private correspondence school sector has been assertive, and sometimes even aggressive. The NUEA and its members shunned this approach, choosing instead to lead by persuasion and example. The NUEA developed standards of practice concerned primarily with replicating on‐campus teaching styles and values, rather than the promotion of distance education. With the abolition of its division structure, the NUEA's successor, the University Continuing Education Association (UCEA), has opted out of a leadership role in independent study. This paper concludes that the NUEA's initial attempt at leadership in distance education— while reasoned and principled—contained flaws that made failure inevitable. 相似文献

Based on a cross-sectional, longitudinal follow-up study of graduates from our master's-level elementary education program, in this article we examined changes in espoused beliefs elicited in the form of personal practical theories (PPTs) of three graduates with 2, 4, and 6 years of experience teaching in the same partnership school where they did their student teaching. We compared their original PPTs collected during their teacher education program with their current PPTs elicited in follow-up interviews, and then observed their classroom practices. Case summaries of these teachers are presented, and analysis and implications focus on changes in their PPTs, how their PPTs played out in their classrooms, and perceived barriers and supports to enacting their beliefs. 相似文献
