The purpose of this paper is to describe the role of the Botswana study-service scheme (Tirelo Setshaba) in the career development of its participants. Study-service is defined as community service used to educate those who participate in contrast to other service programmes where the main objective is to provide manpower e.g. by providing service to the community. First, the existing career development situation in Botswana for senior secondary school students is reviewed and findings from some recent research in this field in the country are presented. Second, the nature of the one year experience gained by Tirelo Setshaba participants is described including the uniqueness of Tirelo Setshaba as compared to other similar schemes in that service takes place before post-secondary education, but with other policies being similar to those developed for university students. Third, the paper presents a rationale for career development assistance for Tirelo Setshaba participants and describes career development material prepared for them. The nature of the scheme, with two or a maximum of four participants assigned to a village, has made it necessary to design a career service for clients who are so widely scattered that the often-used career talks, conventions or one-to-one counselling are impractical. Finally, the paper argues for a proper evaluation of Tirelo Setshaba's impact on career development as the conclusions drawn in the paper are based on limited observations.Senior Research Fellow, National Institute of Development Research and Documentation, University of Botswana.

Abstract

Many studies have found a relationship between students’ self-reported procrastination and their grades. Few studies have used learning analytic data as a behavioural measure of procrastination in order to predict performance, and there is no systematic research on how this relationship may differ across assessments or disciplines. In this study we analyse nine years’ worth of institutional electronic submission records, a total of 73,608 assignment submissions, to examine the relationship between submission time and grades across assignments, students, courses, and disciplines in higher education. A significant negative relationship was found overall, with students who submitted closer to the deadline obtaining lower grades, however the size of the relationship was negligible, accounting for less than 1% of the variance in grades. The relationship varied significantly depending on student, assignment, course and discipline.  相似文献

The goal of this study was to examine the means used by textbook authors to introduce, define, and explain the mole concept in high school and introductory college chemistry textbooks. The analysis was framed by four questions:
  • 1 How is the mole defined?
  • 2 What concepts about the atom are introduced prior to the mole?
  • 3 Is Avogadro's constant presented as an experimentally determined value?
  • 4 What is the context for introducing the mole?
Twenty-nine high school and introductory college level chemistry texts were examined. After independent reading of appropriate sections of each text, discussion of differences, second or third readings of texts, and subsequent discussions, both authors reach 100% agreement concerning the results. Major conclusions were
  • 1 Two ways of defining the mole dominate the texts. One way defines the mole as Avogadro's number (6.02 × 1023) particles; the other method defines the mole in terms of carbon-12.
  • 2 All texts that present a definition in terms of C-12 introduce and define concepts about the atom prior to introducing the mole.
  • 3 Most texts at all levels point out that the value 6.02 × 1023 is an experimentally determined quantity.
  • 4 Nearly all texts discuss the mole in relation to die problem of finding a way to count particles that are too small to be directly weighed. Most texts also use a familiar counting unit, such as the dozen, to introduce the mole by analogy.
Four issues were discussed: (a) the defining attributes of the mole concept itself and the cognitive requirements for comprehending the two most frequently used definitions; (b) the connection between the definition of the mole presented in the text and the concepts about atoms that are introduced before the mole concept is developed; (c) the experimental nature of Avogadro's number; and (d) the context or setting for developing the mole concept.  相似文献

It is well established that technological education is not just about the development of technical expertise. A socially constructed view of technology aims to recognise the culture of technology. Technology education as expressed in the New Zealand curriculum provides an opportunity for societal issues to have equal space with technological capability and technological knowledge. However, when technological activities focus on solutions it is all too easy for stakeholders' positions to be ignored. There is a need for a teaching approach to engage in a liberating technological literacy discourse where values and beliefs of all participants directly and indirectly involved in the activity, are examined. This research monitored a professional development programme where identification of the values represented in a familiar object provided a model for discussion and the development of a teaching environment that promoted consideration of values during problem-solving. The data have been collected from primary school teachers who developed teaching programmes for Years 1 to 8 (5–12 years).  相似文献

In this paper, we investigate the effects of a community- and school-based service learning experience (SLE) on pre-service physical education teachers’ Indigenous knowledge, cultural competency and pedagogy. Informed by the theoretical tenets of Indigenous research methodologies, experiential learning and critical reflection, we examine 55 final-year pre-service physical education teachers’ (age: 21.9 [8.3]; 10.7% low SES; 68% females) cultural learning and competency in a core unit of study with a six-week SLE. Measures of their experiences included reflective journals, multicultural teaching competency scales and focus group interviews. Findings support the design of the SLE, with statistically significant changes in pre-service teachers’ perceptions of their cultural competency (p < 0.001). Pre-service teachers were able to challenge their assumptions about Indigenous students, plan and implement student-centred and culturally relevant pedagogies. Attention is drawn to the design of this SLE and demonstrates the importance of using Indigenous community members and teachers as mentors, which has not been explored in previous SLE studies.  相似文献
