ABSTRACT

Using data from the 2006 Program for International Student Assessment (PISA), we explored nine aspects of science engagement (science self-efficacy, science self-concept, enjoyment of science, general interest in learning science, instrumental motivation for science, future-oriented science motivation, general value of science, personal value of science, and science-related activities) as outcomes and predictors of science achievement. Based on results from multilevel modelling with 4456 students nested within 132 schools, we found that all aspects of science engagement were statistically significantly and positively related to science achievement, and nearly all showed medium or large effect sizes. Each aspect was positively associated with one of the (four) practices (strategies) of science teaching. Focus on applications or models was positively related to the most aspects of science engagement (science self-concept, enjoyment of science, instrumental motivation for science, general value of science, and personal value of science). Hands-on activities were positively related to additional aspects of science engagement (science self-efficacy and general interest in learning science) and also showed a positive relationship with science achievement.  相似文献

The work of science is a linguistic act. However, like history and philosophy of science, language has frequently been isolated from science content due to factors such as school departmentalization and narrow definitions of what it means to teach, know, and do science. This conceptual article seeks to recognize and recognize—to understand and yet rethink—science content in light of the vision of science expected by academic standards. Achieving that vision requires new perspectives in science teaching and teacher education that look into the role that science language expectations play in science content. These perspectives reposition attention to language from a hidden, overlooked, or outsourced aspect of science teaching, to one at its core. To help bring teachers and teacher educators into this integrative view of science content, this article offers a mirror, a prism, and a lens as three metaphorical tools to explore the essential roles that language plays for, in, and as science content. The reflection, refraction, and refocusing of science content reveal complex science language expectations that function alongside facts, figures, and formulas of science as gatekeeping mechanisms that, once noticed, cannot be ignored or marginalized in science teaching and science teacher education.  相似文献

ABSTRACT

The concept of science capital has a growing influence in science education research for understanding young people’s science trajectories. Popularised in the UK, this paper aims to extend and evaluate the applicability of science capital in the context of China by drawing on PISA2015. More specifically, we make use of existing items in the PISA2015 survey as a proxy for operationalising the construct of science capital to explore the science career aspirations and attainments of 15-year-old Chinese and UK students (n?=?23,998). Our findings indicate that science capital has more explanatory power for understanding UK students’ science career aspirations than for Chinese students, where science attainment seems most important. We raise the potential challenge for Chinese students to convert their science capital into scientific self-efficacy and science career aspirations as we highlight the importance of recognising cultural and national differences in operationalising science capital.  相似文献

Every aspect of teaching, including the instructional method, the course content, and the types of assessments, is influenced by teachers’ attitudes and beliefs. Teacher education programs play an important role in the development of beliefs regarding teaching and learning. The purpose of the study was to document pre-service teachers’ views on science, scientists, and science teaching as well as the relations between these views and the offered courses over several years spent in an elementary science teacher training program. The sample consisted of 145 pre-service elementary science teachers who were being trained to teach general science to students in the 6th through 8th grades. The research design was a cross-sectional study. Three different instruments were used to collect the data, namely, the “Draw a Scientist Test”, “Draw a Science Teacher Test”, and “Students’ Views about Science” tests. The elementary science teacher training program influenced pre-service science teachers’ views about science, scientists and science teaching to different degrees. The most pronounced impact of the program was on views about science teaching. Participants’ impressions of science teaching changed from teacher-centered views to student-centered ones. In contrast, participants’ views about scientists and science did not change much. This result could be interpreted as indicating that science teacher training programs do not change views about science and scientists but do change beliefs regarding teaching science.  相似文献

Efforts have been made to promote children's interest in science, but little is known about how children's interest in science relates to other characteristics, such as science‐specific curiosity, domain‐general epistemic curiosity, and verbal intelligence. The current study examines how these factors relate to individual differences in children's self‐reported interest in science topics. Children 7‐ to 10‐years‐old (n = 91) rated their interest in science and non‐science topics and completed measures of science‐specific curiosity, domain‐general epistemic curiosity, and verbal intelligence. An additional 94 7‐ to 10‐year‐olds rated their interest in science and non‐science topics and completed the science‐specific curiosity measure. The results suggest that individual differences in children's science interest relate most strongly to scientific curiosity, and specifically to the drive to seek out information and new experiences.  相似文献

School science systems tend to emphasize teaching and learning about achievements of science (such as laws and theories) at the expense of providing students with opportunities to develop realistic conceptions about science and science inquiry and expertise they could use to conduct their own science inquiry projects. Among reasons for such an emphasis, teachers’ lack of experiences with realistic science inquiry appears to be particularly problematic. Accordingly, we engaged student-teachers in a university-based course that attempted to balance instruction about science and science inquiry with student-teachers’ own theorization about science and science inquiry. Qualitative data collected mainly from nine student-teachers in four focus groups indicate that these student-teachers’ motivation for promoting student-led science inquiry projects in schools significantly increased by the end of the course. Analyses suggest that this outcome was influenced by changes in their conceptions about the nature of science, changes in how they associated science inquiry with student learning, and the inductive-deductive dialectic immersion that was built into their pre-service methods course. Implications of these findings for science teacher education are explored in this paper.  相似文献

The aims of this study were to examine self‐efficacy and other motivation variables among high school science students (n = 502); to determine the degree to which each of the four hypothesized sources of self‐efficacy makes an independent contribution to students' science self‐efficacy beliefs; to examine possible differences between life, physical, and Earth science classes; and to investigate patterns of gender differences that may vary among the fields of science. In Earth science classes, girls earned higher grades and reported stronger science self‐efficacy. In life science classes, girls earned higher grades but did not report stronger self‐efficacy, and did report higher science anxiety. In physical science, there were no gender differences in grades or self‐efficacy, but girls again reported higher levels of science anxiety. For boys across science fields, science self‐efficacy significantly predicted course grades and mastery experiences was the only significant predictor of self‐efficacy. For girls, self‐efficacy was also the strongest predictor of science grade across fields. Mastery experiences significantly predicted self‐efficacy in Earth science for girls, but social persuasions, vicarious experiences, and physiological states were better predictors of science self‐efficacy in life and physical science classes. Results support (Bandura, A., 1997) hypothesized sources of self‐efficacy, previous research findings on self‐efficacy in the domain of science, and validate the suggestion made by Lau and Roeser (2002) to disaggregate data by science field. © 2008 Wiley Periodicals, Inc.

This study investigated the use of a hands-on laboratory program as a means of improving student attitude toward science and increasing student achievement levels in science knowledge. Using a posttest-only control group design, curriculum referenced objective examinations were used to measure student achievement in science knowledge, and a posttest Q-sort survey was used to measure student attitude toward science. A one-way analysis of variance compared the groups' differences in achievement and attitude toward science. Analysis of covariance was used to determine the effect of the laboratory treatment on the dependent achievement variable with attitude toward science as the covariable. The findings showed that students who had regular laboratory instruction (a) scored significantly higher (p < .01) on the objective examination of achievement in science knowledge than those who had no laboratory experiences; (b) exhibited a moderate, positive correlation (r = .406) between their attitude toward science and their achievement; and (c) scored significantly higher (p < .01) on achievement in science knowledge after these scores were adjusted on the attitude toward science covariable. There were no significant differences in achievement or attitude toward science for the limited English proficiency groups. It was concluded that laboratory instruction influenced, in a positive direction, the students' attitude toward science, and influenced their achievement in science knowledge. It was recommended that science instruction include a regular laboratory experience as a demonstrated viable and effective instructional method for science teachers. This model of science instruction has been shown to be effective with students of diverse backgrounds who live within large urban centers. J Res Sci Teach 34: 343–357, 1997.  相似文献

Conclusion This study suggests that most students entering science or science education units in preservice primary teacher education courses have a positive attitude to the teaching/learning of primary science and see value in all domains of science for children at this stage. This was an unexpected finding. It was of concern however, that their interest in physical science topics was so low. This may be due to previous specific experiences in secondary science. Science and science education units should build on the positive attitudes of students and could develop physical science ideas through their significance in environmental and social problems.

Scientific literacy and attitudes toward science play an important role in human daily lives. The purpose of this study was to investigate whether first‐year pre‐service teachers in colleges in Taiwan have a satisfactory level of scientific literacy. The domains of scientific literacy selected in this study include: (1) science content; (2) the interaction between science, technology and society (STS); (3) the nature of science; and (4) attitudes toward science. In this study, the instruments used were Chinese translations of the Test of Basic Scientific Literacy (TBSL) and the Test of Science‐related Attitudes. Elementary education majors (n = 141) and science education majors (n = 138) from four teachers’ colleges responded to these instruments. The statistical results from the tests revealed that, in general, the basic scientific literacy of first‐year pre‐service teachers was at a satisfactory level. Of the six scales covered in this study, the pre‐service teachers displayed the highest literacy in health science, STS, and life science. Literacy in the areas of the nature of science and earth science was rated lowest. The results also showed that science education majors scored significantly higher in physical science, life science, nature of science, science content, and the TBSL than elementary science majors. Males performed better than females in earth science, life science, science content, and the TBSL. Next, elementary education majors responded with more “don’t know” responses than science education majors. In general, the pre‐service teachers were moderately positive in terms of attitudes toward science while science education majors had more positive attitudes toward science. There was no significant difference in attitudes between genders. Previous experience in science indicated more positive attitudes toward science. The results from stepwise regression revealed that STS, the nature of science, and attitudes toward science could explain 50.6% and 60.2% variance in science content in elementary education and science education majors, respectively. For science education majors, the first three scales—the nature of science, health science and physical science—determined basic scientific literacy. However, for elementary education majors, the top three factors were physical science, life science and the nature of science. Based on these results, several strategies for developing the professional abilities of science teachers have been recommended for inclusion in pre‐service programs.  相似文献

This study examined the relationships among Taiwanese high school students’ scientific epistemic beliefs, conceptions of learning science, and self-efficacy of learning science. The questionnaire responses gathered from 377 high school students in Taiwan were utilized to elicit such relationships. The analysis of the structural equation model revealed that students’ absolutist scientific epistemic beliefs led to lower-level conceptions of learning science (i.e. learning science as memorizing, preparing for tests, calculating, and practicing) while sophisticated scientific epistemic beliefs might trigger higher-level conceptions of learning science (i.e. learning science as increase of knowledge, applying, and attaining understanding). The students’ lower-level conceptions of learning science were also found to negatively associate with their self-efficacy of learning science, while the higher-level conceptions of learning science fostered students’ self-efficacy. However, this study found that students who viewed scientific knowledge as uncertain (advanced epistemic belief) tended to possess lower self-efficacy toward learning science.  相似文献

The purpose of this study was to examine the relationships among science content knowledge, understanding the Learning Cycle, and self-efficacy among preservice teachers. Preservice teachers enrolled in an elementary science-methods course were categorized as Fearful, Disinterested, Successful, or Enthusiastic science learners based on differing background characteristics in the variables of science interest, performance in science courses methods courses. Analysis revealed that the four categories increased differentially in their science content knowledge, understanding of the Learning Cycle, science teaching self-efficacy, and confidence to learn science. Fearful science learners demonstrated less increases in science content knowledge and understanding of the Learning Cycle than the other three categories. Disinterested science learners demonstrated fewer gains in science content knowledge than Enthusiastic science learners. Fearful science learners were less confident to learn science than other categories.

This study explored the effects that the incorporation of nature of science (NoS) activities in the primary science classroom had on children’s perceptions and understanding of science. We compared children’s ideas in four classes by inviting them to talk, draw and write about what science meant to them: two of the classes were taught by ‘NoS’ teachers who had completed an elective nature of science (NoS) course in the final year of their Bachelor of Education (B.Ed) degree. The ‘non-NoS’ teachers who did not attend this course taught the other two classes. All four teachers had graduated from the same initial teacher education institution with similar teaching grades and all had carried out the same science methods course during their B.Ed programme. We found that children taught by the teachers who had been NoS-trained developed more elaborate notions of nature of science, as might be expected. More importantly, their reflections on science and their science lessons evidenced a more in-depth and sophisticated articulation of the scientific process in terms of scientists “trying their best” and “sometimes getting it wrong” as well as “getting different answers”. Unlike children from non-NoS classes, those who had engaged in and reflected on NoS activities talked about their own science lessons in the sense of ‘doing science’. These children also expressed more positive attitudes about their science lessons than those from non-NoS classes. We therefore suggest that there is added value in including NoS activities in the primary science curriculum in that they seem to help children make sense of science and the scientific process, which could lead to improved attitudes towards school science. We argue that as opposed to considering the relevance of school science only in terms of children’s experience, relevance should include relevance to the world of science, and NoS activities can help children to link school science to science itself.  相似文献

Ethnographic research methodologies were used to examine the training of elementary education majors in science in an attempt to gain insight on whether or not their training in science contributes to the apprehension elementary teachers have toward science. The field study consisted of 14 weeks of weekly observations in the elementary education majors science methods class. Interviews with the students and the instructors as well as survey instruments to assess students' preparation in science were used. Two different approaches to the study of science, one content oriented, the other process oriented, may contribute to the students' confusion, insecurity, and avoidance of science. The students' perception that science is learning content, an objective of introductory level science courses, and the science methods class's objectives of teaching science as a process sets up an “antagonistic dilemma” between the two. Such “antagonistic dilemma” may be manifest in the lack of instructional time accorded to science by elementary educators. The type of science experiences an individual encounters influences their perceptions. To offset student perceptions developed in science courses which stress principally content, the students need science experiences which truly represent science as inquiry. New strategies for the training of elementary education majors in science need to be examined.  相似文献

Teacher education programs have adopted preparing science teachers that teach science through inquiry as an important pedagogic agenda. However, their efforts have not met with much success. While traditional explanations for this failure focus largely on preservice science teachers’ knowledge, beliefs and conceptions regarding science and science teaching, this conceptual paper seeks to direct attention toward discursive practices surrounding inquiry science teaching in teacher education programs for understanding why most science teachers do not teach science through inquiry. The paper offers a theoretical framework centered on critical notions of subjection and performativity as a much needed perspective on making/becoming of science teachers through participation in discursive practices of science teacher education programs. It argues that research based on such perspectives have much potential to offer a deeper understanding of the difficult challenges teacher education programs face in preparing inquiry practicing science teachers.  相似文献
