The 2015 Programme for International Student Assessment (PISA) has drawn a substantial amount of attention from science educators and educational policymakers because it marked the first time that PISA assessed students' ability to evaluate and design scientific inquiry using computer-based simulations. We undertook a secondary analysis of the PISA 2015 Taiwan dataset of 7,973 students from 214 schools to identify critical issues of student learning and potentially reshape our educational system and policies. Thus, this study sought to identify potential latent clusters of students' scientific literacy performance according to a set of focus variables selected from the PISA student questionnaires. In addition, significant determinants of students' scientific literacy and resiliency were analyzed. Cluster analysis results demonstrated the presence of four clusters of high, medium, low, and inferior scientific literacy/epistemology/affective dispositions. Specifically, students in cluster 1 compared with other clusters showed that the higher the scientific literacy scores are, the more positive epistemic beliefs about science, achievement motivation, enjoyment of science, interests in broad science, science self-efficacy, information and communications technology (ICT) interest, ICT autonomy, more learning time, more teacher supports and teacher-directed instructions are. Regression results indicated that the most robust predictor of students' scientific literacy performance is epistemic beliefs about science, followed by learning time, interest in broad science topics, achievement motivation, inquiry-based science teaching and learning practice, and science self-efficacy. Decision tree model results showed that the descending order of the variables in terms of their importance in differentiating students as high- versus low-performing were epistemic beliefs about science, learning time, self-efficacy, interest in broad science, and scientific inquiry, respectively. A similar decision tree model to determine students as resilient versus non-resilient also was found. Various interpretations of these results are discussed, as are their implications for science education research, science teaching, and science education policy.  相似文献

ABSTRACT

The purpose of this study was to develop and validate two survey instruments to evaluate high school students' scientific epistemic beliefs and goal orientations in learning science. The initial relationships between the sampled students' scientific epistemic beliefs and goal orientations in learning science were also investigated. A final valid sample of 600 volunteer Taiwanese high school students participated in this survey by responding to the Scientific Epistemic Beliefs Instrument (SEBI) and the Goal Orientations in Learning Science Instrument (GOLSI). Through both exploratory and confirmatory factor analyses, the SEBI and GOLSI were proven to be valid and reliable for assessing the participants' scientific epistemic beliefs and goal orientations in learning science. The path analysis results indicated that, by and large, the students with more sophisticated epistemic beliefs in various dimensions such as Development of Knowledge, Justification for Knowing, and Purpose of Knowing tended to adopt both Mastery-approach and Mastery-avoidance goals. Some interesting results were also found. For example, the students tended to set a learning goal to outperform others or merely demonstrate competence (Performance-approach) if they had more informed epistemic beliefs in the dimensions of Multiplicity of Knowledge, Uncertainty of Knowledge, and Purpose of Knowing.  相似文献

Teaching science as explanation is fundamental to reform efforts but is challenging for teachers—especially new elementary teachers, for whom the complexities of teaching are compounded by high demands and little classroom experience. Despite these challenges, few studies have characterized the knowledge, beliefs, and instructional practices that support or hinder teachers from engaging their students in building explanations. To address this gap, this study describes the understandings, purposes, goals, practices, and struggles of one third-year elementary teacher with regard to fostering students' explanation construction. Analyses showed that the teacher had multiple understandings of scientific explanations, believed that fostering students' explanations was important for both teachers and students, and enacted instructional practices that provided opportunities for students to develop explanations. However, she did not consistently take up explanation as a goal in her practice, in part because she did not see explanation construction as a strategy for facilitating the development of students' content knowledge or as an educational goal in its own right. These findings inform the field's understanding of teacher knowledge and practice with regard to one crucial scientific practice and have implications for research on teachers and inquiry-oriented science teaching, science teacher education, and curriculum materials development.  相似文献

Science includes more than just concepts and facts, but also encompasses scientific ways of thinking and reasoning. Students' cultural and linguistic backgrounds influence the knowledge they bring to the classroom, which impacts their degree of comfort with scientific practices. Consequently, the goal of this study was to investigate 5th grade students' views of explanation, argument, and evidence across three contexts—what scientists do, what happens in science classrooms, and what happens in everyday life. The study also focused on how students' abilities to engage in one practice, argumentation, changed over the school year. Multiple data sources were analyzed: pre‐ and post‐student interviews, videotapes of classroom instruction, and student writing. The results from the beginning of the school year suggest that students' views of explanation, argument, and evidence, varied across the three contexts with students most likely to respond “I don't know” when talking about their science classroom. Students had resources to draw from both in their everyday knowledge and knowledge of scientists, but were unclear how to use those resources in their science classroom. Students' understandings of explanation, argument, and evidence for scientists and for science class changed over the course of the school year, while their everyday meanings remained more constant. This suggests that instruction can support students in developing stronger understanding of these scientific practices, while still maintaining distinct understandings for their everyday lives. Finally, the students wrote stronger scientific arguments by the end of the school year in terms of the structure of an argument, though the accuracy, appropriateness, and sufficiency of the arguments varied depending on the specific learning or assessment task. This indicates that elementary students are able to write scientific arguments, yet they need support to apply this practice to new and more complex contexts and content areas. © 2011 Wiley Periodicals, Inc.

This article examines how the Dual‐Situated Learning Model (DSLM) facilitates a radical change of concepts that involve the understanding of matter, process, and hierarchical attributes. The DSLM requires knowledge of students' prior beliefs of science concepts and the nature of these concepts. In addition, DSLM also serves two functions: it creates dissonance with students' prior knowledge by challenging their epistemological and ontological beliefs about science concepts, and it provides essential mental sets for students to reconstruct a more scientific view of the concepts. In this study, the concept “heat transfer: heat conduction and convection,” which requires an understanding of matter, process, and hierarchical attributes, was chosen to examine how DSLM can facilitate radical conceptual change among students. Results show that DSLM has great potential to foster a radical conceptual change process in learning heat transfer. Radical conceptual change can definitely be achieved and does not necessarily involve a slow or gradual process. © 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 142–164, 2004  相似文献

ABSTRACT

Context-based learning (CBL), promoting students' scientific text comprehension, and fostering metacognitive skills, plays an important role in science education. Our study involves CBL through comprehension and analysis of adapted scientific articles. We developed a module which integrates metacognitive prompts for guiding students to monitor their understanding and improve their scientific text comprehension. We investigated the effect of these metacognitive prompts on scientific text comprehension as part of CBL in chemistry. About 670 high school chemistry students were randomly divided into three groups exposed to high- and low-intensity CBL. One of the high-intensity groups was also exposed to metacognitive prompts. Research tools included pre- and post-questionnaires aimed at measuring students' conceptual chemistry understanding and metacognitive knowledge in the context of reading strategies, before and after exposure to the CBL. Chemistry understanding was reflected by students' ability to identify the main subject of the adapted article and by explaining concepts both textually and visually. We found that high-intensity CBL combined with metacognitive prompts improved students' chemistry understanding of the adapted scientific articles and the ability to regulate their learning. Our study establishes that reading context-based adapted scientific articles advances students' conceptual chemistry understanding. These gains are strongly amplified by domain-specific metacognitive prompts.  相似文献

Although research from a developmental/psychological perspective indicates that many children do not have a scientific understanding of living things, even by the age of 10 years, little research has been conducted about how students learn this science topic in the classroom. This exploratory research used a case‐study design and qualitative data‐collection methods to investigate the process of conceptual change from ontological and social perspectives when Year 1 (5‐ and 6‐year‐old) students were learning about living things. Most students were found to think about living things with either stable, nonscientific or stable, scientific framework theories. Transitional phases of understanding also were identified. Patterns of conceptual change observed over the 5‐week period of instruction included theory change and belief revision as well as reversals in beliefs. The predominant pattern of learning, however, was the assimilation of facts and information into the students' preferred framework theory. The social milieu of the classroom context exposed students' scientific and nonscientific beliefs that influenced other individuals in a piecemeal fashion. Children with nonscientific theories of living things were identified as being least able to benefit from socially constructed, scientific knowledge; hence, recommendations are made for teaching that focuses on conceptual change strategies rather than knowledge enrichment. © 2004 Wiley Periodicals, Inc.

So far scholars have researched beliefs about knowledge, knowing, and learning mainly in the areas of science and mathematics and among secondary school students. In this article, we explore primary school students' metacognitive beliefs about religious education. The article reports on a study involving 656 fifth- and sixth-grade students. We investigated their metacognitive beliefs, how these beliefs interrelate, and which students agree with which beliefs. In the minds of young students 7 categories are discernible: realistic learning, the transformative power of religion, social learning, intrinsic task value motivation, learning satisfaction motivation, the teacher's empathic orientation to learning, and the teacher's respect for students' contributions. These categories and their interrelationships open up new perspectives for the construction of a metacognitive beliefs system and for an interconnected network of beliefs across domains. We also outline implications for religious education in schools.  相似文献

Authentic activities are important in promoting inquiry because they provide natural problem-solving contexts with high degrees of complexity. This study designed and studied effective inquiry tasks through transforming content, scientific thinking, and resources featured in scientists' authentic practices. This study investigated how 59 inner-city 6th grade students performed in real-time forecasting situations involving fronts and pressure systems. Forecasts were evaluated in terms of prediction agreement, meteorological entity consideration, explanation type, and scientific knowledge use because these four categories reflected inquiry features emphasized in the forecasting task. Results show that real-world situations that mapped closely onto students' content understandings, rather than those with naturally occurring complex patterns, helped students perform inquiry. Key ideas discussed in this paper include the importance of using authentic situations to develop rich understandings about scientific knowledge and the design of tasks that prepare students to participate in social practices valued by the science community.  相似文献

Students' epistemological beliefs about scientific knowledge and practice are one important influence on their approach to learning. This article explores the effects that students' inquiry during a 4‐week technology‐supported unit on evolution and natural selection had on their beliefs about the nature of science. Before and after the study, 8 students were interviewed using the Nature of Science interview developed by Carey and colleagues. Overall, students held a view of science as a search for right answers about the world. Yet, the inconsistency of individuals' responses undermines the assumption that students have stable, coherent epistemological frameworks. Students' expressed ideas did not change over the course of the intervention, suggesting important differences between students' talk during inquiry and their abilities to talk epistemologically about science. Combined with previous work, our findings emphasize the crucial role of an explicit epistemic discourse in developing students' epistemological understanding. © 2003 Wiley Periodicals, Inc.

In a science methods course for elementary education majors, students investigated the phases of the moon for six weeks. The moon investigation emphasized that scientific knowledge: a) is empirically based; b) involves the invention of explanations; and c) is socially embedded. After the moon investigation, students realized that scientists make observations and generate patterns, but failed to recognize that observation could precede or follow theory building. Students could separate the processes of observing from creating explanations in their learning, but did not articulate the role of invention in science. Similarly, students valued the social dimensions of learning, but were unable to apply them to the activity of scientists. Although our teaching was explicit about students' science learning, we did not help them make direct connections between their science learning activities and the nature of science [NOS]. We provide a set of recommendations for making the NOS more explicit in the moon investigation.  相似文献

The importance of students' learning to learn competence for academic achievement, as well as their well-being at school and in life, is increasingly emphasised by educators and policy makers in national curricula and educational strategies. In an uncertain and complex world, learners need to become autonomous, be able to analyse challenges and apply knowledge in different contexts, address complex tasks, and create new knowledge. This article explores concepts and approaches to the development of students' learning to learn competence in the context of education in Estonia. First, the conceptualisation, model and dimensions of learning to learn competence are described and related challenges for teachers are analysed. Second, an overview of Estonian teachers' current practices, beliefs, knowledge, skills and occupational standards relevant to students' learning to learn competence is provided. We discuss how Estonian teacher education policy may enhance or inhibit the work of teachers when supporting students to develop learning to learn competence. Future directions for teacher educators and how to prepare teachers to support the development of students' learning to learn competence are suggested.  相似文献

This study examined the relationship between students' (N = 229) concepts of size and scale and students' achievement in science and mathematics over a 3-year period. Size and scale are considered one of the big ideas in science that permeates disparate science and mathematics content areas, yet little is known about the relationship between students' conceptualization of size and scale and students' achievement in science and mathematics. The study used a modified panel longitudinal design to follow the same class of students over a 3-year period. The goal was to explore whether understandings of size and scale are related to achievement in mathematics and science. Results indicated a strong positive significant relationship existed between students' understanding of size and scale and students' science achievement in grades 5 and 8. There was a positive significant relationship between students' concepts of size and scale and students' mathematics achievement in grades 5, 6, 7, and 8. An examination of the relationships is included as well as a discussion of the integration of crosscutting concepts into science and mathematics instruction as a way to support deep learning.  相似文献

The purpose of this study was to determine the beliefs about biological evolution held by college freshman students in one Catholic university in the Philippines. After 4 weeks of constructivist-inspired instruction, interviews and journal entries revealed that the students have diverse beliefs about the theory of evolution. They posited rejection, acceptance or doubt about the evolutionary theory based on their scientific and theological beliefs, perceptions about the evidence of evolution and misconceptions about evolutionary theory, in particular, human evolution. Based on the results, it is discerned that there indeed is a clear interaction between science and religion in the teaching and learning of science. The authors also conclude that students' current worldviews, in the form of attitudes and beliefs, affect how they understand concepts.  相似文献

Abstract

In England, both Religious Education (RE) and science are mandatory parts of the school curriculum throughout the 5-16 age range. Nevertheless, there remain concerns that, as in many countries, students do not have a good understanding about the scope of each subject nor about how the two subjects relate. This article reports on a study that involved an intervention of six lessons in RE and six in science that were intended to help 13-15?year-old students develop a better appreciation for the relationship(s) between science and religion and a less reductionist understanding of biology. Our focus here is on the understandings that students have about the relationship between science and religion. The intervention was successful in improving the understandings of almost half of the students interviewed, but in these interviews we still found many instances where students showed misunderstandings of the nature of both religious and scientific knowledge. We argue that RE needs to attend to questions regarding the nature of knowledge if students are to develop better understandings of the scope of religions and how they arrive at their knowledge claims.  相似文献

We describe the implementation of a specially designed teaching innovation, embedded in the context of energy, for the promotion of specific aspects of the nature of science (NOS). We present empirical results from the implementation of the teaching and learning materials in three intact sixth-grade classes that involved a total of 64 students. We report on students' learning gains and we discuss the ensuing implications for teaching and learning with an emphasis on epistemic ideas. The integration of activities promoting understandings of energy and specific aspects of the NOS seems to work well in impacting on students' epistemic awareness. The findings reveal interesting aspects about the interplay between understandings of energy and the NOS. The article also illustrates that it is possible to teach productively specific aspects of a consensus view of the NOS from a fairly young age without having to rely on advanced science knowledge or explore the intricacies and differentiations across science disciplines.  相似文献

The purpose of the study was to determine the level of the relationship among Turkish elementary school students' personal epistemologies, motivation, learning strategies, and achievements in science. A total of 322 fifth-grade students participated in the study. Results from the structural equation modeling showed that students' personal epistemologies influence both their motivation and metacognitive strategies in science learning. Viewing scientific knowledge as constructed by the learner contributes to the students having high motivations, high science achievement, and the ability to engage metacognitively in learning tasks.  相似文献

Abstract

This study assessed 4th, 8th, and 11th grade students' understanding of natural and social science concepts related to pollution. A representative sample of public school students (n = 105) in 11 Maine schools was selected, and students were interviewed on four concept principles considered critical to a full understanding of the pollution problem. The concept of pollution included the much publicized issues of solid and toxic waste as well as air, soil, and water pollution. Research assertions were summarized in generalized correct concept statements indicating the extent of current student knowledge. Common misconceptions were also noted.

This study considered student understanding from a human ecological perspective, that is, as an integrated set or cluster of concepts related to pollution. This reflects a complex, integrated, and multidisciplinary conception of natural phenomena. Human constructivism, meaningful learning theory, and principles related to the relevance of student schema in the design of curriculum and instructional strategies guided this work.

The results of this study have implications for teaching about pollution and the design of science education curriculum materials based upon student knowledge. This information can guide teaching strategies concerning current environmental problems and thus help learners gain an appreciation for the complex and multi-disciplinary nature of science, technology, and society and how they affect the environment.  相似文献
