This study chronicled the professional journeys of two beginning science teachers. The focus of the research effort documents
what brought them to science teaching and investigated their resulting career paths. Data artifacts for this instrumental
case study approach included: interviews, written survey responses, personal communications and member checks. All data was
transcribed and coded into emergent categories using a constant comparative analysis approach. The findings indicated that
their decisions to enter and leave teaching were a complex mélange of issues that included career disposition, notions of
isolation, overarching culture of the school, and future possibilities. However, most striking was their re-entry into teaching
on a temporary basis after considerable time away from the classroom, which suggests that teachers develop a sense of agency
regarding their career decisions. This may require researchers to reconsider how we view teacher decision-making within the
context of teacher attrition and mobility. Implications for science teacher education indicate that some teachers may enter
the profession considering teaching to be a transition into a different career path. Secondary science teachers may perceive
multiple career options (beyond the classroom) based on their preparation and teaching experience. Further implications and
possibilities for science teacher education are discussed. 相似文献

This paper explores the potential impact of a national pilot initiative in England aimed at increasing and widening participation
in advanced mathematical study through the creation of a new qualification for 16- to 18-year-olds. This proposed qualification
pathway—Use of Mathematics—sits in parallel with long-established, traditional advanced level qualifications, what we call ‘traditional Mathematics’ herein. Traditional Mathematics is typically required for entry to mathematically demanding undergraduate programmes. The structure, pedagogy and assessment
of Use of Mathematics is designed to better prepare students in the application of mathematics, and its development has surfaced some of the tensions
between academic/pure and vocational/applied mathematics. Here, we explore what Use of Mathematics offers, but we also consider some of the objections to its introduction in order to explore aspects of the knowledge politics
of mathematics education. Our evaluation of this curriculum innovation raises important issues for the mathematics education
community as countries seek to increase the numbers of people that are well prepared to apply mathematics in science and technology-based
higher education courses and work places. 相似文献

This study investigated the distribution of incentives (e.g., certificates, badges) for massive open online course (MOOC) completion, and relationships between incentives and MOOC outcomes. Participants were 779 MOOC students internationally who participated in at least 303 different MOOCs offered by at least 12 providers. MOOC participants most commonly intended to receive, and in actuality received, free and paid course certificates of completion; other incentives (e.g., digital badges, postsecondary credits) were far less common. In addition, MOOC participants' intentions to receive both free and paid certificates were consistently and positively related to perceived learning and course completion, net other factors. (Keywords: massive open online courses, MOOCs, motivation, incentives, microcredentials, certificates of completion) 相似文献

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.

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?
- 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.

We examine classroom situations which allow the learning of rules of mathematical reasoning. Drawing on an epistemological analysis and G. Brousseau's theory of situations, we define a priori theoretical characteristics which such situations must possess. We then use this analysis, and hypotheses about the cognitive functioning of pupils of this age, to establish learning situations for the rule of the excluded middle, and for the use of the figure in geometry. We report the results of experimentation with two of thses situations and show that, through the study of a mathematical problem, debate about these rules can be generated amongst students aged twelve to thirteen. We explain why, in our opinion, for epistemological reasons linked to the two particular rules concerned, it is necessary for the teacher to conclude the debate, and we examine our cognitive hypotheses against the actual results of experimentation. 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
