The purpose of this research was to build and test a conceptual model of the complex interrelationships between students' learning in science (learning approaches and self-regulation), their reading comprehension, question-asking in class and science achievement. These variables were measured by means of a test and a series of questionnaires administered to 604 ninth-grade students, and the data collected were analysed using a correlational, cross-sectional design. Results of a path analysis indicated that (a) students’ self-regulated and intentional knowledge-constructing activity (self-regulated strategy use, deep approach and knowledge-building) were what chiefly accounted for their question-asking in class; (b) question-asking (high and low levels) was related directly to reading comprehension and indirectly, through its contribution to the this, to academic achievement; (c) reading comprehension was directly and negatively associated with surface approach and indirectly and positively related to deep approach and knowledge-building; and (d) some of these variables, particularly reading comprehension, accounted for academic achievement in science. This model explained nearly 30% of the variance in academic achievement and provided a substantial and distinctive insight into the web of interrelationships among these variables. Implications for future research and science teaching and learning are discussed (e.g. the importance of supporting students' efforts to learn science in a meaningful, active and self-regulated way and of improving their reading comprehension). 相似文献

Summaries English The purpose of this article is to promote awareness of a growing body of literature concerned with the relationship between the epistemology of science and school science education, and to stimulate debate concerning the role such epistemological considerations should play in the professional training of science teachers. First of all, a rationale is provided for the inclusion of the epistemology of science and its relationship to school science education as an essential component on the professional training of all science teachers. This is followed by a review of existing resources for use in science teacher education curricula, and suggestions for new resource material. Finally, a possible curriculum for inclusion in science teacher education programmes is presented. 相似文献

In this paper, we report a case study of a 16-year-old Swedish upper secondary student's developing understanding of key concept areas studied in his upper secondary school chemistry course. This study illustrates how the thinking of an individual learner, Jesper, evolves over a school year in response to formal instruction in a particular educational context. Jesper presented a range of ideas, some of which matched intended teaching whilst others were quite inconsistent with canonical chemistry. Of particular interest, research data suggest that his initial alternative conceptions influenced his thinking about subsequent teaching of chemistry subject matter, illustrating how students' alternative conceptions interact with formal instruction. Our findings support the claims of some researchers that alternative conceptions may be stable and tenacious in the context of instruction. Jesper's rich conceptualisation of matter at submicroscopic scales drew upon intuitions about the world that led to teaching being misinterpreted to develop further alternative conceptions. Yet his intuitive thinking also offered clear potential links with canonical scientific concepts that could have been harnessed to channel his developing thinking. These findings support the argument that identifying students' intuitive thinking and how it develops in different instructional contexts can support the development of more effective science pedagogy. 相似文献

Gauging the effectiveness of specific teaching strategies remains a major topic of interest in science education. Inquiry teaching among others has been supported by extensive research and recommended by the National Science Education Standards. However, most of the empirical evidence in support was collected in research settings rather than in normal school environments. Propensity score analysis was performed within the marginal mean weighting through stratification (MMW-S) approach to examine the effects of the level of openness of inquiry teaching on student science achievement and attitudes with the Programme for International Student Assessment (PISA) 2006 data. Weighting subjects on MMW-S weight successfully balanced all treatment groups on all selected covariates. Significant effects were identified on both cognitive and attitudinal outcomes. For student science achievement, the highest score was achieved at Level 2 inquiry teaching, that is, students conduct activities and draw conclusions from data. For student science attitudes, higher level of inquiry teaching resulted in higher scores. The said conclusions were generally held in most PISA 2006 participating countries when the analysis was performed in each country separately. 相似文献

Science educators have called for using the learning progression approach to align curriculum, instruction, and assessment. In line with this trend, we conducted both assessments and teaching experiments with students from grades 4 to 12 (717 students participated in the pre-assessments and 682 students participated in the post-assessments). The goal of the study is to develop a learning progression framework that provides effective guidance for curriculum and instruction on carbon-transforming processes in socio-ecological systems. We conducted the study in three research cycles. We developed a matter-and-energy learning progression framework during the first two cycles. This learning progression framework was used to guide the teaching intervention in the third research cycle. Clinical interviews and written assessments were implemented before and after the teaching intervention. In the process of data analysis, we found that the matter-and-energy learning progression framework did not provide a fine-grained depiction of students' reasoning. Therefore, we developed the five-practice learning progression framework, and used it to re-analyze data. Results indicate that the teaching intervention has helped students to achieve significant learning gains, but it was not effective enough in helping students achieve the upper anchor of the learning progression framework—constructing sophisticated scientific explanations. The results also indicate that students tended to rely on coherent and consistent reasoning to construct explanations. Based on the findings, we provide instructional suggestions and discuss the implications for climate change education and learning progression research. 相似文献

The ongoing reform in science education in many countries, including Israel, has attainment of scientific literacy for all as one of its main goals. In this context, it is important to provide teachers with the opportunity to construct meaning for the term science literacy and by doing so to obtain a clear understanding of the new teaching goals. Here we report on a study in which teachers, as part of their professional development, were involved in defining the term ‘chemical literacy’; they discussed the need for it, and suggested educational experiences that are necessary in order to attain it. The programme was conducted as part of a reform in the content, as well as in the pedagogy, of chemistry education in Israel. The collected data provide some insights regarding the process by which the teachers’ perception of ‘chemical literacy’ developed and the way actual school practice influences teachers’ perception of ‘chemical literacy’. 相似文献

This paper reports on a study of primary contextualization processes during science immersion trips and the resultant student learning. Four High School Ecology classes (n?=?67) and teachers participated. Through a pre-/post-assessment of science concept knowledge (Pathfinder Network Modeling) and follow-up interviews with students, it was determined that (1) significant learning was associated with these immersion experiences, though overcontextualization was problematic for some, (2) there was a positive interaction between degree of contextualization (primary vs. secondary) and degree of learning, and (3) key primary contextualization processes included the situating of knowledge in time and place as well as the collection of personalized visual or embodied evidence for science concepts. The study contributes to our understanding of contextualization in the learning process and has the potential to inform field, classroom, and virtual learning environments. 相似文献

The main purpose of this study was to concurrently investigate Taiwanese high-school students' and their science teachers' conceptions of learning science (COLS) and conceptions of science assessment (COSA). A total of 1,048 Taiwanese high-school students and their 59 science teachers were invited to fill out two questionnaires assessing their COSA and COLS. The main results indicated that, first, although a handful of different patterns occurred, students and teachers were found to have similar COLS–COSA patterns. In general, students and teachers with COSA as reproducing knowledge and rehearsing tended to possess lower-level COLS, such as learning science as memorizing, testing, and calculating and practicing. In contrast, if students and teachers viewed science assessment as improving learning and problem-solving, they would be prone to regard science learning as increase of knowledge, applying, and understanding and seeing in a new way. However, the students' conceptions did not align with those of the teachers' in certain aspects. The students tended to regard science learning and assessment at a superficial level (COLS as ‘memorizing’, ‘testing’, and ‘calculating and practicing’ and COSA as ‘reproducing knowledge’), while the teachers’ conceptions were at a more sophisticated level (COLS as ‘application’ and ‘understanding and seeing in a new way’ and COSA as ‘improving learning’). It is evident that a dissonance exists between the students' and teachers' COLS and COSA. Based on the results, practical implications and suggestions for future research are discussed. 相似文献

This study describes the process of defining a hypothetical learning progression (LP) for astronomy around the big idea of Solar System formation. At the most sophisticated level, students can explain how the formation process led to the current Solar System by considering how the planets formed from the collapse of a rotating cloud of gas and dust. Development of this LP was conducted in 2 phases. First, we interviewed middle school, high school, and college students (N?=?44), asking them to describe properties of the current Solar System and to explain how the Solar System was formed. Second, we interviewed 6th-grade students (N?=?24) before and after a 15-week astronomy curriculum designed around the big idea. Our analysis provides evidence for potential levels of sophistication within the hypothetical LP, while also revealing common alternative conceptions or areas of limited understanding that could form barriers to progress if not addressed by instruction. For example, many students' understanding of Solar System phenomena was limited by either alternative ideas about gravity or limited application of momentum in their explanations. Few students approached a scientific-level explanation, but their responses revealed possible stepping stones that could be built upon with appropriate instruction. 相似文献
