The study examined the differences in cognitive styles between two comparable groups of students at the Grade 9 (Secondary 3) level, namely the LSS (Lower Secondary Science) group who had been exposed to the practical-based, inquiry-oriented type of science and the non-LSS group of students who had studied the more traditional type of science in the “old” science curriculum. Their differences in science achievement are measured by the common IEA Science Paper-Pencil, Multiple Choice Criterion Test and also, by the Science Process or Practical Test (which measured three levels of process skills, such as the observation/manipulation, reasoning and investigation skills). Variance in science achievement thus measured is examined against the 4 cognitive preference styles of the students, (measured by the Combined Cognitive Preference Inventory) namely the “recall”, “principles”, “applications” and “questioning” modes of thinking. The findings indicated that (a) the attainment of the science process or practical skills was characterised by the type of science curriculum (LSS or non-LSS) and it was significantly associated with the achievement level of students, (b) the cognitive preference pattern covaried according to the students' level of science achievement and the type of curriculum and (c) the weak but significant relationship between performance in the science practical skills and the students' modes of cognitive style have important implications for teachers who are concerned about the intended effects of changes in the science curriculum on the consequent learning behaviour or cognitive outcome of their students. 相似文献

Health professionals and policymakers are asking educators to place more emphasis on food and nutrition education. Integrating these topics into science curricula using hand‐on, food‐based activities may strengthen students’ understanding of science concepts. The Food, Math, and Science Teaching Enhancement Resource (FoodMASTER) Initiative is a compilation of programs aimed at using food as a tool to teach mathematics and science. Previous studies have shown that students experiencing the FoodMASTER curriculum were very excited about the activities, became increasingly interested in the subject matter of food, and were able to conduct scientific observations. The purpose of this study was to: (1) assess 4th graders food‐related multidisciplinary science knowledge, and (2) compare gains in food‐related science knowledge after implementation of an integrated, food‐based curriculum. During the 2009–2010 school year, FoodMASTER researchers implemented a hands‐on, food‐based intermediate curriculum in eighteen 4th grade classrooms in Ohio (n = 9) and North Carolina (n = 9). Sixteen classrooms in Ohio (n = 8) and North Carolina (n = 8), following their standard science curricula, served as comparison classrooms. Students completed a researcher‐developed science knowledge exam, consisting of 13 multiple‐choice questions administered pre‐ and post‐test. Only subjects with pre‐ and post‐test scores were entered into the sample (Intervention n = 343; Control n = 237). No significant differences were observed between groups at pre‐test. At post‐test, the intervention group scored (9.95 ± 2.00) significantly higher (p = 0.000) than the control group (8.84 ± 2.37) on a 13‐point scale. These findings suggest the FoodMASTER intermediate curriculum is more effective than a standard science curriculum in increasing students’ multidisciplinary science knowledge related to food. 相似文献

Previous research has shown that indigenous students in Australia do not enjoy equal educational outcomes with other Australians. This secondary analysis of PISA 2006 confirmed that this continues to be the case in science literacy for secondary students. However, the analysis also revealed that indigenous Australian students held interest in science equal to that of their non‐indigenous peers, and that observed variations in science literacy performance were most strongly explained by variations in reading literacy. These findings hold important implications for teachers, teacher educators, policy‐makers, and researchers. Firstly, acknowledging and publicly valuing indigenous Australian science knowledge through rethinking school science curriculum seems an important approach to engaging indigenous students and improving their literacy in science. Secondly, appropriate professional learning for practising teachers and the incorporation of indigenous knowing in science methods training in teacher preparation seems warranted. Additionally, we offer a number of questions for further reflection and research that would benefit our understanding of ways forward in closing the science literacy gap for indigenous students. Whilst this research remains firmly situated within the Australian educational context, we at the same time believe that the findings and implications offered here hold value for science education practitioners and researchers in other countries with similar populations striving to achieve science literacy for all. 相似文献

Background: In Bangladesh, a common science curriculum caters for all students at the junior secondary level. Since this curriculum is for all students, its aims are both to build a strong foundation in science while still providing students with the opportunities to use science in everyday life – an aim consistent with the notion of scientific literacy.Purpose: This paper reports Bangladeshi science teachers’ perspectives and practices in regard to the promotion of scientific literacy.Sample: Six science teachers representing a range of geographical locations, school types with different class sizes, lengths of teaching experience and educational qualifications.Design and method: This study employed a case study approach. The six teachers and their associated science classes (including students) were considered as six cases. Data were gathered through observing the teachers’ science lessons, interviewing them twice – once before and once after the lesson observation, and interviewing their students in focus groups.Results: This study reveals that participating teachers held a range of perspectives on scientific literacy, including some naïve perspectives. In addition, their perspectives were often not seen to be realised in the classroom as for teachers the emphasis of learning science was more traditional in nature. Many of their teaching practices promoted a culture of academic science that resulted in students’ difficulty in finding connections between the science they study in school and their everyday lives. This research also identified the tension which teachers encountered between their religious values and science values while they were teaching science in a culture with a religious tradition.Conclusions: The professional development practice for science teachers in Bangladesh with its emphasis on developing science content knowledge may limit the scope for promoting the concepts of scientific literacy. Opportunities for developing pedagogic knowledge is also limited and consequently impacts on teachers’ ability to develop the concepts of scientific literacy and learn how to teach for its promotion. 相似文献

Student‐directed, open‐ended scientific investigations and invention projects may serve to deepen and broaden students’ scientific and technological literacy, and, in so doing, enable them to succeed in democracies greatly affected by processes and products of science and technology. Science fairs, events at which student‐led projects are evaluated and celebrated, could contribute to such positive personal and social outcomes. Qualitative data drawn from a national science fair over succeeding years indicate (after analyses of largely qualitative data, using constant comparative methods) that, apart from positive outcomes regarding science literacy, there may be some significant issues about the fair that warrant critical review. It is apparent from these studies that there are issues of access, image, and recruitment associated with the fair. Qualification for participation in the fair appears to favour students from advantaged, resource‐rich backgrounds. Although these students do benefit in a number of ways from the fair experience, it is apparent that science fairs also greatly benefit sponsors—who can, in a sense, use science fairs for promotional and recruitment purposes. These findings and claims raised, for us, some important questions possibly having implications for science education, and for society more generally. 相似文献

In this paper, I report on a school‐university collaborative research project that investigated which practices and knowledges of Canadian Aboriginal students not acknowledged in school may provide these students with access to school literacy practices. The study, which took place in a small city in Western Canada, examined ways to merge the out‐of‐school literacy resources with school literacy practices for minority language learners who struggle with academic literacies. Drawing on the third space theory, in conjunction with the concept of “funds of knowledge,” I explain how students' linguistic and cultural resources from home and community networks were utilised to reshape school literacy practices through their involvement in the Heritage Fair programme. I analyse a representative case study of Darius, a 10‐year‐old boy who explored his familial hunting practices for his Heritage Fair project. This illustrative exemplar, “Not just sunny days,” highlights the ways in which children's out‐of‐school lives can be used as a scaffold for literacy learning. In conclusion, I discuss implications for educators and researchers working to improve literacy learning for minority students by connecting school learning to children's out‐of‐school learning. 相似文献

Forty‐four Head Start classrooms were randomly assigned to enriched intervention (Head Start REDI—Research‐based, Developmentally Informed) or “usual practice” conditions. The intervention involved brief lessons, “hands‐on” extension activities, and specific teaching strategies linked empirically with the promotion of: (a) social‐emotional competencies and (b) language development and emergent literacy skills. Take‐home materials were provided to parents to enhance skill development at home. Multimethod assessments of three hundred and fifty‐six 4‐year‐old children tracked their progress over the course of the 1‐year program. Results revealed significant differences favoring children in the enriched intervention classrooms on measures of vocabulary, emergent literacy, emotional understanding, social problem solving, social behavior, and learning engagement. Implications are discussed for developmental models of school readiness and for early educational programs and policies. 相似文献

The notion of “science for all” suggests that all students—irrespective of achievement and ability—should engage in opportunities to understand the practice and discourse of science. Improving scientific literacy is an intrinsic goal of science education, yet current instructional practices may not effectively support all students, in particular, students with special needs. Argument‐based inquiry approaches, such as the Science Writing Heuristic (SWH), require all students to construct their scientific understandings by engaging in investigations and negotiating their ideas in multiple contexts, such as discussions and writing. Various SWH studies demonstrated that students engaged in appropriating the language, culture, practice, and dispositions of science generally improved their critical thinking and standardized test scores. The implementation of such an approach has several implications for science and special education research and practice, including how learning environments should be established to encourage the inclusion of all students’ ideas, as well as how scaffolded supports can and should be used to support science learning. 相似文献

Recent studies question the effectiveness of a traditional university curriculum in helping students improve their critical thinking and scientific literacy. We developed an introductory, general education (gen ed) science course to overcome both deficiencies. The course, titled Foundations of Science, differs from most gen ed science offerings in that it is interdisciplinary; emphasizes the nature of science along with, rather than primarily, the findings of science; incorporates case studies, such as the vaccine-autism controversy; teaches the basics of argumentation and logical fallacies; contrasts science with pseudoscience; and addresses psychological factors that might otherwise lead students to reject scientific ideas they find uncomfortable. Using a pretest versus posttest design, we show that students who completed the experimental course significantly improved their critical-thinking skills and were more willing to engage scientific theories the general public finds controversial (e.g., evolution), while students who completed a traditional gen ed science course did not. Our results demonstrate that a gen ed science course emphasizing the process and application of science rather than just scientific facts can lead to improved critical thinking and scientific literacy. 相似文献

In recent years, a number of curriculum reform projects have championed the notion of having students do science in ways that move beyond hands‐on work with authentic materials and methods, or developing a conceptual grasp of current theories. These reformers have argued that students should come to an understanding of science through doing the discipline and taking a high degree of agency over investigations from start to finish. This stance has occasionally been mocked by its critics as an attempt to create “little scientists”—a mission, it is implied, that is either romantic or without purpose. Here, we make the strong case for a practice‐based scientific literacy, arguing through three related empirical studies that taking the notion of “little scientists” seriously might be more productive in achieving current standards for scientific literacy than continuing to refine ideas and techniques based on the coverage of conceptual content. Study 1 is a classroom case study that illustrates how project‐based instruction can be carried out when teachers develop guidance and support strategies to bootstrap students' participation in forms of inquiry they are still in the process of mastering. Study 2 shows how sustained on‐line work with volunteer scientists appears to influence students' success in formulating credible scientific arguments in written project reports following an authentic genre. Study 3, using data from three suburban high school classes, suggests that involving students in the formulation of research questions and data analysis strategies results in better spontaneous use of empirical data collection and analysis strategies on a transfer task. The study also suggests that failing to involve students in the formulation of research can result in a loss of agency. The implications of these findings for future research and practice are discussed. © 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 234–266, 2004 相似文献

Engaging undergraduate students in research has become increasingly important due to its potential benefits (for example, increased intention to pursue postgraduate study and enhanced understanding of theoretical knowledge). This study investigated whether a comprehensive food science research project that was incorporated into the laboratory component of an Experimental Study of Foods course would enhance student knowledge, confidence, and interest in research. A total of 84 students participated in two sections of the laboratory (2016, n = 39; 2017, n = 45). Scores for pre and posttests and questionnaires were used to determine if the differences in knowledge scores and ratings for confidence in doing research were significant. Knowledge scores indicated that participants were knowledgeable about research at baseline (2016, 7.31 ± 1.15; 2017, 6.89 ± 0.1.21; maximum of 10 points). Results of the t‐tests showed that the change in knowledge scores before and after the project was not statistically significant; however, the level of confidence in performing various research skills (for example, identify research questions, formulate hypotheses, design an experiment) significantly increased upon project completion. In general, students demonstrated favorable attitudes toward the research project at the end of this project. Qualitative responses were organized into three themes that related to the “input” (elements that made the project successful), “process” (how the project was conducted), and “outcomes” (reported gains or benefits) of the project. Recommendations were made in terms of mentorship, research guidelines and topics, and group culture to improve future projects. 相似文献

This paper sets out an argument and approach for moving beyond a primarily arts‐based conceptualization of cultural capital, as has been the tendency within Bourdieusian approaches to date. We advance the notion that, in contemporary society, scientific forms of cultural and social capital can command a high symbolic and exchange value. Our previous research [Archer et al. (2014) Journal of Research in Science Teaching 51, 1–30] proposed the concept of “science capital” (science‐related forms of cultural and social capital) as a theoretical lens for explaining differential patterns of aspiration and educational participation among young people. Here, we attempt to theoretically, methodologically, and empirically advance a discussion of how we might conceptualize science capital and how this might be translated into a survey tool for use with students. We report on findings from a survey conducted with 3658 secondary school students, aged 11–15 years, in England. Analysis found that science capital was unevenly spread across the student population, with 5% being classified as having “high” science capital and 27% “low” science capital. Analysis shows that levels of science capital (high, medium, or low) are clearly patterned by cultural capital, gender, ethnicity, and set (track) in science. Students with high, medium, or low levels of science capital also seem to have very different post‐16 plans (regarding studying or working in science) and different levels of self‐efficacy in science. They also vary dramatically in terms of whether they feel others see them as a “science person.” The paper concludes with a discussion of conceptual and methodological issues and implications for practice. © 2015 The Authors.

Background: Scientific excellence is one of the most fundamental underpinnings of medical education and its relevance is unquestionable. To be involved in research activities enhances students' critical thinking and problem-solving capacities, which are mandatory competences for new achievements in patient care and consequently to the improvement of clinical practice. Purposes: This work aimed to study the relevance given by Portuguese medical students to a core of scientific skills, and their judgment about their own ability to execute those skills. Methods: A cross-sectional study was conducted on students attending the first, fourth and sixth years of medical course in the same period. An assessment istrument, exploring the importance given by Portuguese medical students to scientific skills in high school, to clinical practice and to their own ability to execute them, was designed, adapted and applied specifically to this study. Results: Students' perceptions were associated with gender, academic year, previous participation in research activities, positive and negative attitudes toward science, research integration into the curriculum and motivation to undertake research. The viewpoint of medical students about the relevance of scientific skills overall, and the ability to execute them, was independently associated with motivation to be enrolled in research. Conclusions: These findings have meaningful implications in medical education regarding the inclusion of a structural research program in the medical curriculum. Students should be aware that clinical practice would greatly benefit from the enrollment in research activities. By developing a solid scientific literacy future physicians will be able to apply new knowledge in patient care. 相似文献

This investigation explores how underrepresented urban students made sense of their first experience with high school science. The study sought to identify how students' assimilation into the science classroom reflected their interpretation of science itself in relation to their academic identities. The primary objectives were to examine students' responses to the epistemic, behavioral, and discursive norms of the science classroom. At the completion of the academic year, 29 students were interviewed regarding their experiences in a ninth and tenth‐grade life science course. The results indicate that students experienced relative ease in appropriating the epistemic and cultural behaviors of science, whereas they expressed a great deal of difficulty in appropriating the discursive practices of science. The implications of these findings reflect the broader need to place greater emphasis on the relationship between students' identity and their scientific literacy development. © 2005 Wiley Periodicals, Inc.

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

Purdue Univ.'s College of Agriculture developed an Advanced Life Sciences (ALS) program in partnership with several high schools across Indiana. As part of ALS, secondary educators take an introductory food science (FS) course (ALS‐Foods) and teach it at their high school. High school students taking the ALS‐Foods receive dual credit for an introductory course required for all FS majors at Purdue. The goal of this project was to develop an online course to improve content knowledge and self‐efficacy of secondary educators in the field of FS. The course was offered over a 3‐wk period and consisted of 3 learning modules focused on food chemistry, food microbiology, and food processing. Modules included class activities, videos, study questions, and teaching tools. Participants were assessed on content knowledge through written assignments, quizzes, and a final examination. Twenty secondary educators from several states were enrolled. Overall, content knowledge increased significantly (P < 0.05) across all 3 modules after completing the course. Highest scores were in food microbiology/safety (84%), followed by food processing (76%) and food chemistry (70%). A precourse survey indicated that the majority (>80%) of participants felt they had “no‐confidence” to “little‐confidence” in teaching FS concepts related to the 3 modules. Upon completing the course, the confidence level of all participants increased to “some‐confidence” or “complete confidence.” By strengthening the knowledge level of secondary educators, they will be better prepared to teach FS and subsequently, more high school students could be exposed to FS and consider it as a career. 相似文献
