Abstract

The authors focus on exploiting new methods of language acquisition with the help of the possibilities offered by the Internet. As a new option for computer‐assisted language learning, the Internet is considered to be a source for individual learning and problem oriented teaching in many other areas. Expanding knowledge in parallel in informatics and the English language is an asset. In addition to pointing out starting off sites for ESL teachers and introducing some interesting examples, some criteria of constructing language teaching WWW pages of our own are also listed.  相似文献

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

This paper is concerned with issues affecting equity in science education for girls and boys. In the paper the results of an investigation into the recently published (1998–2000) series of textbooks entitled Lower Secondary Science for Brunei Darussalam are presented. In the first part of the paper, background issues of continuing gender inequality in science education and of the nature and scope of textbook analyses are outlined. Then the representation of males and females in both illustrations and text in the Bruneian textbooks is discussed. From this analysis a picture emerges of the extent to which science is portrayed as a pursuit of equal appropriateness for both boys and girls. The paper concludes with a consideration of the implications of the findings presented within the wider context of gender and education in Brunei.  相似文献

Through a qualitative interview design, this study investigated how participation in a rigorous academic environment may influence gifted students who demonstrate high levels of perfectionism. The study also examined how their responses to a rigorous academic and residential environment may differ according to the type of perfectionism. Findings indicated that some socially prescribed perfectionists reported an increase in perfectionism, whereas some self-oriented perfectionists reported an increase followed by a decrease in their perfectionism. Overall, the majority of the participants, regardless of their type of perfectionism, indicated a decrease in their perfectionism as a result of their new academic environment. Reactions to experiencing imperfections ranged from calm to guilt or even anger, depending on the type of perfectionism. Implications for working with gifted students who show high levels of perfectionism are discussed.  相似文献
