基于学习共同体的“校-研-教”华文校本协同研究术

新加坡华文教学队伍在教育部的鼓励与推动下,近10年掀起了以改进华文教学为出发点的校本研究风。当前已有的以学者专家为主导和以一线教师为主导的两种研究模式,都对教师专业成长和教学质量持续提升帮助甚微。协同研究主张结合研究者和实践者的经验与专长,共谋专业知识的提升和实践有效的教学形式,为校本研究提供了一个新的研究方向。南洋理工大学下属新加坡华文教研中心参与的两项校本研究案例显示,基于学习共同体的校本协同研究是提高教学质量、促使教师反思、促进教师教育技术专业发展的有效手段。成功的校本研究,要建立学校领导、研究人员和教师三方组成的“校一研一教”学习共同体,以“协同研究”为取向,建立对研究课题目的、方法和策略的研究共识,合理分工,促进与提高“互补性贡献”,抑制或消除“矛盾性期待”,充分发挥三方的经验与专长,促进教师反思与专业成长,实现教学质量的实质性提高。     

Making inquiry-based science learning visible: the influence of CVS and cognitive skills on content knowledge learning in guided inquiry

ABSTRACT

Many science curricula and standards emphasise that students should learn both scientific knowledge and the skills associated with the construction of this knowledge. One way to achieve this goal is to use inquiry-learning activities that embed the use of science process skills. We investigated the influence of scientific reasoning skills (i.e. conceptual and procedural knowledge of the control-of-variables strategy) on students’ conceptual learning gains in physics during an inquiry-learning activity. Eighth graders (n?=?189) answered research questions about variables that influence the force of electromagnets and the brightness of light bulbs by designing, running, and interpreting experiments. We measured knowledge of electricity and electromagnets, scientific reasoning skills, and cognitive skills (analogical reasoning and reading ability). Using structural equation modelling we found no direct effects of cognitive skills on students’ content knowledge learning gains; however, there were direct effects of scientific reasoning skills on content knowledge learning gains. Our results show that cognitive skills are not sufficient; students require specific scientific reasoning skills to learn science content from inquiry activities. Furthermore, our findings illustrate that what students learn during guided inquiry activities becomes visible when we examine both the skills used during inquiry learning and the process of knowledge construction. The implications of these findings for science teaching and research are discussed.     

Logical positivism as a tool to analyse the problem of chemistry's lack of relevance in secondary school chemical education

Secondary school chemical education has a problem: namely, the seeming irrelevance to the pupils of chemistry. Chemical education prepares pupils for participation in society. Therefore, it must imply a model of society, of chemistry, and of the relation between them. In this article it is hypothesized that logical positivism currently offers this model. Logical positivism is a philosophy of science that creates a divide between science and society. It is therefore further hypothesized that the adoption of logical positivism causes chemistry's lack of relevance in chemical education. Both hypotheses could be confirmed by an analysis of a grade nine course.     

Essential Criteria to Characterize Constructivist Teaching: Derived from a review of the literature and applied to five constructivist‐teaching method articles

Constructivism is an important theory of learning that is used to guide the development of new teaching methods, particularly in science education. However, because it is a theory of learning and not of teaching, constructivism is often either misused or misunderstood. Here we describe the four essential features of constructivism: eliciting prior knowledge, creating cognitive dissonance, application of new knowledge with feedback, and reflection on learning. We then use the criteria we developed to evaluate five representative published articles that claim to describe and test constructivist teaching methods. Of these five articles, we demonstrate that three do not adhere to the constructivist criteria, whereas two provide strong examples of how constructivism can be employed as a teaching method. We suggest that application of the four essential criteria will be a useful tool for all professional educators who plan to implement or evaluate constructivist teaching methods.     

Primary teachers conducting inquiry projects: effects on attitudes towards teaching science and conducting inquiry

ABSTRACT

This study used an experimental, pretest-posttest control group design to investigate whether participation in a large-scale inquiry project would improve primary teachers’ attitudes towards teaching science and towards conducting inquiry. The inquiry project positively affected several elements of teachers’ attitudes. Teachers felt less anxious about teaching science and felt less dependent on contextual factors compared to the control group. With regard to attitude towards conducting inquiry, teachers felt less anxious and more able to conduct an inquiry project. There were no effects on other attitude components, such as self-efficacy beliefs or relevance beliefs, or on self-reported science teaching behaviour. These results indicate that practitioner research may have a partially positive effect on teachers’ attitudes, but that it may not be sufficient to fully change primary teachers’ attitudes and their actual science teaching behaviour. In comparison, a previous study showed that attitude-focused professional development in science education has a more profound impact on primary teachers’ attitudes and science teaching behaviour. In our view, future interventions aiming to stimulate science teaching should combine both approaches, an explicit focus on attitude change together with familiarisation with inquiry, in order to improve primary teachers’ attitudes and classroom practices.     

Complexity of Secondary Scientific Data Sources and Students’ Argumentative Discourse

This study examined the learning opportunities provided to students through the use of complex geological data supporting scientific inquiry. Through analysis of argumentative discourse in a high school Earth science classroom, uses of US Geological Survey (USGS) data were contrasted with uses of geoscience textbook data. To examine these differences, we conducted a review of frameworks for argumentation analysis, and through adaptation to the research foci of this study, developed a new analytic approach. Applying this approach to student classroom discourse revealed the affordances and constraints of both the complex USGS datasets and the filtered textbook data sources. The challenges of teaching with complex data are presented.     

US Urban Elementary Teachers’ Knowledge and Practices in Teaching Science to English Language Learners: Results from the first year of a professional development intervention

The study examined US elementary teachers’ knowledge and practices in four key domains of science instruction with English language learning (ELL) students. The four domains included: (1) teachers’ knowledge of science content, (2) teaching practices to promote scientific understanding, (3) teaching practices to promote scientific inquiry, and (4) teaching practices to support English language development during science instruction. The study was part of a larger five‐year research and development intervention aimed at promoting science and literacy achievement of ELL students in urban elementary schools. It involved 32 third grade, 21 fourth grade, and 17 fifth grade teachers participating in the first‐year implementation of the intervention. Based on teachers’ questionnaire responses and classroom observation ratings, results indicated that (1) teachers’ knowledge and practices were within the bounds of acceptability but short of reform‐oriented practices and (2) grade‐level differences existed, especially between Grades 3 and 5.     

Creating case studies of practice through Appreciative Inquiry

Taking a positive view is a fruitful way to prompt educators to reflect on and to develop their practice. Teachers, teacher educators and children bring a wide range of ideas that provide a powerful basis for developing understanding of the complexities of classroom practice. Using appreciate inquiry the authors show how they developed their understanding of professional development as they worked with groups of teachers who investigated their science teaching practice with young children and produced case studies of practice. The authors also show how the roles and ideas of themselves as university tutors were challenged and emerged to suit the range of contexts involved. Their view of Continuing Professional Development was influenced by the lived experiences of the teachers and themselves. They worked to systematise learning through identifying commonalities of experience and reflection along four dimensions: creating spaces for growth; working with emergent purposes; action research as rhizomatic growth; and collaborative and collective action. The rich variety of outcomes shows the value of creating space for growth for children and for adults. The energy and enthusiasm liberated motivated the participants to explore their worlds in ways that were difficult to predict at the start of the project.
