This article presents a ‘knowledge ecosystem’ model of how early career academics experience using information to learn while building their social networks for developmental purposes. Developed using grounded theory methodology, the model offers a way of conceptualising how to empower early career academics through (1) agency (individual and relational) and (2) facilitation of personalised informal learning (design of physical and virtual systems and environments) in spaces where developmental relationships are formed, including programmes, courses, events, community, home and social media. It is suggested that the knowledge ecosystem model is suitable for use in designing informal learning experiences for early career academics.  相似文献

Abstract

We present a first-hand, longer-term account of one student’s (Christine’s) experiences in and after a mathematics inquiry course. In this course, students actively posed problems, conducted their own mathematical explorations, and wrote journal entries about their experiences. During the course, Christine found that inquiry helped her develop mathematical content knowledge and a deeper understanding of the nature of research. After the course, Christine became a mathematics education faculty member in a mathematics department and reports that the course impacted the way she teaches mathematics. This provides an illustrative case of the potential long-lasting benefits of an inquiry course.  相似文献

The purpose of this study was to demonstrate the respective effects of cognitive abilities and personality traits on academic achievement. The subjects were 141 sixth-grade French adolescents (mean age: 12) who took three cognitive tests (g factor, numerical ability, and spatial ability) and answered a personality questionnaire based on the Big Five Model. Path analyses indicated that Openness-intellect had an effect on junior high school achievement in all disciplines, with most effects being indirect ones mediated by verbal achievement (French). Neuroticism-anxiety also had an effect, although not as marked and mainly on mathematics. Personality is complementary to abilities in predicting academic achievement. Possible conceptual extensions and field applications are addressed in the conclusion.  相似文献

Human generated environmental problems are significant issues of global concern. Despite this, varying attitudes towards environments continue to exist across the globe, impacting on environmental decision-making and action at local, national and international levels. This paper probes some of the similarities and differences in environmental attitudes amongst pre-service teachers in Australia, Republic of Maldives and Indonesia. Data were collected using an established environmental attitude questionnaire and individual interviews. The three communities exhibited a similar range of environmental attitudes using the established questionnaire but significant differences emerged when the interview data were analysed phenomenographically. These differences reflect diversity within and across cultural groups that cannot be satisfactorily explained by the theory underpinning the established questionnaire. Consequently, a revised conceptual framework is proposed.  相似文献

Recent increased interest in computational thinking poses an important question to researchers: What are the best ways to teach fundamental computing concepts to students? Visualization is suggested as one way of supporting student learning. This mixed-method study aimed to (i) examine the effect of instruction in which students constructed visualizations on students’ programming achievement and students’ attitudes toward computer programming, and (ii) explore how this kind of instruction supports students’ learning according to their self-reported experiences in the course. The study was conducted with 58 pre-service teachers who were enrolled in their second programming class. They expect to teach information technology and computing-related courses at the primary and secondary levels. An embedded experimental model was utilized as a research design. Students in the experimental group were given instruction that required students to construct visualizations related to sorting, whereas students in the control group viewed pre-made visualizations. After the instructional intervention, eight students from each group were selected for semi-structured interviews. The results showed that the intervention based on visualization construction resulted in significantly better acquisition of sorting concepts. However, there was no significant difference between the groups with respect to students’ attitudes toward computer programming. Qualitative data analysis indicated that students in the experimental group constructed necessary abstractions through their engagement in visualization construction activities. The authors of this study argue that the students’ active engagement in the visualization construction activities explains only one side of students’ success. The other side can be explained through the instructional approach, constructionism in this case, used to design instruction. The conclusions and implications of this study can be used by researchers and instructors dealing with computational thinking.  相似文献

The direction that secondary school reform should take has become a contested question in the province of Ontario, Canada, during the 1990s. This case study of one secondary school examines some of the issues surrounding the transition years. Two policies, destreaming and integration, mandatedbythe OntarioMinistryof Education in 1993, and fully implemented by 1995, are examined by means of interview and survey. Administrators, teachers and students commented on the transition from elementary to secondary school. We discuss questions related to destreaming (especially how teachers contend with mixed-ability classes) and integration (with a particular focus on mathematics, science and technology).  相似文献

Abstract

This study examines the development of source evaluation skills in four groups of students from 10 to 19 years of age. We designed a set of tasks based on a distinction between three components of source evaluation: the identification of source parameters; the evaluation of source features such as the source’s competence or benevolence under explicit instructions; and the use of source features in assessing a document’s relevance with respect to a given task. This inventory was administered to 245 teenagers in grades 5, 7 and 9 and to undergraduate students. All types of source evaluation skills developed throughout adolescence, with some of them remaining suboptimal for older readers. Furthermore, we found weak relationships between students’ identification of source parameters and their use of source features in the absence of any specific prompt. Finally, source evaluation tasks were weakly related to teenagers’ word reading skills. Taken together, these results document teenagers’ acquisition of source evaluation skills and warrant a distinction between readers’ ability to comprehend source features and to use these features when assessing information quality.  相似文献

Academic integrity is important to universities and students must abide by codes of academic conduct around assessment. Students are, however, subject to multiple pressures around assessment, some of which can push them to cheat. Modern contract cheating websites are the fronts for sophisticated, commercial operations that offer individually written assessment items for a fee; to combat their use we need a better understanding of the tools they use to persuade students to become customers. In this study we examined the persuasive features of 11 highly-visible contract cheating websites and mapped these features to a previously used persuasiveness framework. We find that contract-cheating websites use a variety of credibility, interactive and informative features designed to persuade students to use their services. In addition, the sites offer low-cost, customisable products available in very short timeframes. We suggest ways in which educators can encourage academic integrity by talking with their students about how the websites promulgate their ‘just turn to us’ message.  相似文献
