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

The quest for culture‐free or even culture‐fair tests of abilities has not succeeded. In their place, a culture‐specific approach to testing is suggested to identify talent hidden by socioeconomic deprivation. The culture‐specific approach to testing for artistic talent in black students suggested here is “Tactuality.” Tactuality was constructed by finding characteristics common to black cultural strengths and the artistically talented. The four characteristics of Tactuality identified were: emotional intensity, flexibility and open‐endedness, holistic perception, and tactile sensitivity. A Tactuality Test (Tac Test) was devised based on these four characteristics. The Tac Test was pilot tested with 63 fourth‐graders comprising an ethnic mixture. Statistical problems with validation occurred, requiring further statistical analysis and a larger test population.  相似文献

As California's complexion and social panorama changes in color and class so must the directions for writing ethnicity and social analysis. This qualitative study seeks to break out of paradigmatic insulation by proposing innovative perspectives and directions for creating subversive narratives about our own realities. It also seeks to inform current social analysis about Mexicana quality of life and about educationalpolicy on Mexicana educacion (education of the whole person) and school cultures. This article examines how Mexicana identities are created, shaped, and developed through the construction of narratives. I interpret these with the analytical tools of trenzas that ''braids'' critical race theory and multidimensional feminist frames, platicas (popular conversations) and cultural intuition, and the engagement of myself, the researcher, and the young Mexicanas participating in the study. By claiming our space and voicing our feelings and meanings about language, Aztlan culture and identity, and womanhood, we correct stereotypic representations that render Mexicanas vulnerable and dismissed from U.S. civic life and public education. In light of the missing discourse about young Mexicana identity formations, this research makes possible trenzas ''braids'' of multiple identities and tools for transforming educational research, curriculum, and the building of education partnerships.  相似文献
