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

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

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

This article outlines BPRS funded investigations into my own school's and other establishments' practices and processes within data analysis, needs identification and tracking of children's academic progress. It describes the evaluation of my school's then current practices and policies and the use of questionnaires and semi-structured interviews with my own staff, and assessment coordinators and senior leaders within exemplar schools. As well as outlining the main findings of my research this article assesses the introduction of new models of assessment for my own staff and pupils. This article also highlights how my research developed and the way my research process changed as it continued.  相似文献

The concept of “open access” to scientific and teaching information has become one of the specific forms of the worldwide trend towards the formation of global interactive knowledge. This paper presents the basic information on open access (OA) to scientific and teaching information, its current status, financing options, problems and prospects of development, and the participation of Russia in this process.  相似文献

The main aspects of the creation of a monitoring system for the research activities of the members of a higher-education institution are considered. The scientific activities of the lecturers and members of Turgenev Orel State University is used as the basis. It is expected that this system will be an efficient tool for optimal managerial decisions at all levels.  相似文献
