In theory, practical work is an established part of university-level chemistry courses. However, mainly due to budget constraints, large class size, time constraints and inadequate teacher preparations, practical activities are frequently left out from chemistry classroom instruction in most developing countries. Small-scale chemistry (SSC) experimentation in which one uses miniature chemical equipment can drastically reduce quantities of chemicals used during experimentation, which can help overcome some of the barriers preventing practical work in the chemistry classroom. This study evaluated the effectiveness of using miniature chemical equipment at the undergraduate level in increasing students’ understanding of chemistry concepts as well as in improving their attitude towards chemistry practical work. Two comparable groups of first-year students who enrolled for a Practical General Chemistry course participated. A quasi-experimental design was employed in which the experimental group (N = 49) used the SSC approach while the control group (N = 52) followed the traditional approach for over 8 weeks. Data were gathered using chemistry tests, attitude and perception questionnaires and interviews. Findings showed that the SSC approach was as effective as the traditional laboratory approach in improving students’ attitude towards practical work, but more effective in enhancing students’ understanding of chemistry concepts. More interestingly, SSC was positively accepted by both students and instructors as an effective strategy for teaching first-year undergraduate chemistry practicals. Some shortcomings of the approach were also identified.  相似文献   

Student teachers' subject matter knowledge within the domain of area measurement   总被引：3，自引：0，他引：3  

Annette Baturo  Rod Nason 《Educational Studies in Mathematics》1996,31(3):235-268

This paper describes a research project whose major aim was to evaluate first-year teacher education students' understanding of subject matter knowledge in the domain of area measurement. In contrast to many previous approaches to evaluating teacher education students' subject matter knowledge, the approach adopted in this study not only focused on the student teachers' substantive knowledge but also on their knowledge about the nature and discourse of mathematics, their knowledge about mathematics in society and their dispositions towards mathematics. To this end, each student was clinically interviewed whilst engaged on a set of eight tasks that were developed for the study. The development of the tasks was a major component of the study and this is described in detail. The results of the tasks are given and the paper concludes with a discussion of the findings. This discussion focuses primarily on the implications that these results have for preservice mathematics education courses.  相似文献

Finding Nexus: connecting youth work and research practices          下载免费PDF全文

Sinéad Gormally  Annette Coburn 《British Educational Research Journal》2014,40(5):869-885

Participation in educational and social research helps to develop understanding of how young people learn and to consider wider aspects of their lives to enable their voices to be heard and acted upon. Research also facilitates the articulation and sharing of methodologies across a range of professional practices. We assert that theory and practice in educational youth work offers a position of strength from which to undertake research. In making this assertion, we suggest cross‐disciplinarity between youth work and research practices in order to build research mindedness among youth workers who, through this nexus, are well‐placed to engage in practice based research. Drawing on discourses about young people, youth work and youth participation, we identify five elements of youth work practice that can be aligned with research processes: reflexivity; positionality and bias; insider cultural competence; rapport and trust; power relationships. The article examines how these elements are present in youth work and a range of research settings. We identify youth work methods and dispositions as enhancing research capacity which could also be useful in building participatory research methods in disciplinary areas beyond education. Yet, in making these connections, we also identify a range of factors that show this nexus as complex and contestable. Reflecting on the lessons learned from our experiences as youth work practitioners and academic researchers, we propose that finding nexus, which in this instance is between youth work and research paradigms, could inform educational research practices and contributes to developing a meaningful praxis.  相似文献   

Exploring “STEM-Readiness” in Public Libraries

Abstract

Many public libraries are offering Science, Technology, Engineering, and Mathematics (STEM) programing to their patrons. Using data from a national survey of public library professionals, the current study examined the growing STEM movement by measuring “STEM-readiness” and through the lens of Diffusion of Innovations Theory. Results indicate that most libraries are ready to implement STEM programing. Characteristics of STEM-ready libraries included serving more patrons, having more space, and engaging more often with STEM programing. Such findings suggest that public libraries that have access to resources are more likely to be STEM-ready; whereas, those with fewer resources may need additional support.  相似文献   

Assessing Students' Understandings of Biological Models and their Use in Science to Evaluate a Theoretical Framework     

Juliane Grünkorn  Annette Upmeier zu Belzen  Dirk Krüger 《International Journal of Science Education》2013,35(10):1651-1684

Research in the field of students’ understandings of models and their use in science describes different frameworks concerning these understandings. Currently, there is no conjoint framework that combines these structures and so far, no investigation has focused on whether it reflects students' understandings sufficiently (empirical evaluation). Therefore, the purpose of this article is to present the results of an empirical evaluation of a conjoint theoretical framework. The theoretical framework integrates relevant research findings and comprises five aspects which are subdivided into three levels each: nature of models, multiple models, purpose of models, testing, and changing models. The study was conducted with a sample of 1,177 seventh to tenth graders (aged 11–19 years) using open-ended items. The data were analysed by identifying students' understandings of models (nature of models and multiple models) and their use in science (purpose of models, testing, and changing models), and comparing as well as assigning them to the content of the theoretical framework. A comprehensive category system of students' understandings was thus developed. Regarding the empirical evaluation, the students' understandings of the nature and the purpose of models were sufficiently described by the theoretical framework. Concerning the understandings of multiple, testing, and changing models, additional initial understandings (only one model possible, no testing of models, and no change of models) need to be considered. This conjoint and now empirically tested framework for students' understandings can provide a common basis for future science education research. Furthermore, evidence-based indications can be provided for teachers and their instructional practice.  相似文献

Dispelling Myths about Latino Parent Participation in Schools     

Alice M. L. Quiocho  Annette M. Daoud 《The Educational forum》2013,77(3):255-267

This qualitative study was conducted to discuss and dispel commonly held myths about Latino parents' involvement in their children's education. Differences between teacher perceptions of Latino parent involvement and parents' understanding of their roles in supporting their children's education—including the learning and use of the English language—were explored. Results indicated that some teachers held negative perceptions of Latino parents. The study also revealed that Latino parents had high expectations of their children's academic achievement and wanted to be more involved in their education, but felt excluded from the school community.  相似文献   

Reducing anxiety in gifted children by inducing relaxation     

David W. Chan  Lai-kwan Chan  Annette Chi-yan Chan 《Roeper Review》2013,35(3):177-186

Sixty-four parents of Chinese gifted children who reported themselves to be traditional or Westernized parents were compared on their endorsement of Chinese traditional and Western parenting values and beliefs as well as their parenting style dimensions in terms of dominating control, guan, and warmth. Regardless of their degrees of Westernization, these parents seemed to be more characterized by collectivistic than individualistic thinking approaches based on Nisbett's conceptualization. More Westernized parents valued nonconformity significantly more than conformity, whereas less-Westernized parents placed more emphasis on the importance of unconditional respect for elders and interdependence than on conditional respect and child independence. Regarding parenting styles and practices, though all parents endorsed the practice of warmth significantly more, followed by guan, and significantly less dominating control, there was suggestive evidence that less-Westernized parents practiced guan more than more-Westernized parents. Implications of the findings for parenting gifted children are discussed.  相似文献
