3D printing technology is a powerful educational tool that can promote integrative STEM education by connecting engineering, technology, and applications of science concepts. Yet, research on the integration of 3D printing technology in formal educational contexts is extremely limited. This study engaged preservice elementary teachers (N?=?42) in a 3D Printing Science Project that modeled a science experiment in the elementary classroom on why things float or sink using 3D printed boats. The goal was to explore how collaborative 3D printing inquiry-based learning experiences affected preservice teachers’ science teaching self-efficacy beliefs, anxiety toward teaching science, interest in science, perceived competence in K-3 technology and engineering science standards, and science content knowledge. The 3D printing project intervention significantly decreased participants’ science teaching anxiety and improved their science teaching efficacy, science interest, and perceived competence in K-3 technological and engineering design science standards. Moreover, an analysis of students’ project reflections and boat designs provided an insight into their collaborative 3D modeling design experiences. The study makes a contribution to the scarce body of knowledge on how teacher preparation programs can utilize 3D printing technology as a means of preparing prospective teachers to implement the recently adopted engineering and technology standards in K-12 science education.  相似文献

Research Findings: Quality early science education is important for addressing the low science achievement, compared to international peers, of elementary students in the United States. Teachers’ beliefs about their skills in a content area, that is, their content self-efficacy is important because it has implications for teaching practice and child outcomes. However, little is known about how teachers’ self-efficacy for literacy, math and science compare and how domain-specific self-efficacy relates to teachers’ practice in the area of science. Analysis of survey and observation data from 67 Head Start classrooms across eight programs indicated that domain-specific self-efficacy was highest for literacy, significantly lower for science, and lowest for math. Classrooms varied, but in general, engaged in literacy far more than science, contained a modest amount of science materials, and their instructional support of science was low. Importantly, self-efficacy for science, but not literacy or math, related to teachers frequency of engaging children in science instruction. Teachers’ education and experience did not predict self-efficacy for science. Practice or Policy: To enhance the science opportunities provided in early childhood classrooms, pre-service and in-service education programs should provide teachers with content and practices for science rather than focusing exclusively on literacy.  相似文献

The objective of this study was to explore the relationships between academic hardiness in science, conceptions of learning science, and science learning self-efficacy among Malaysian middle school students. The respondents were 320 eighth-grade students from two selected Malaysian middle schools. Three questionnaires were used for this survey: Academic Hardiness in Science (AHS) regarding “commitment,” Conceptions of Learning Science (COLS), including “memorizing,” “calculating and practicing,” and “understanding and seeing in a new way,” and Science Learning Self-Efficacy (SLSE), consisting of “cognition,” “practical work,” “everyday application,” and “science communication.” These three questionnaires were validated and found to be reliable for measuring students’ AHS, COLS, and SLSE. Pearson’s correlation findings indicated that AHS was significantly and positively correlated to all the factors in COLS and SLSE, and all the factors in COLS were significantly and positively correlated to all the factors in SLSE. The relationships among AHS, COLS, and SLSE were then identified by the structural equation model technique. Students with a high commitment to learning science, and who perceived learning science as understanding and seeing in a new way are prone to have confidence at all levels of science learning self-efficacy.

Uncertainty about ethics has been a major factor in societal rejection of biotechnology. Six factors help create a societal “perfect storm” regarding ethics and biotechnology: Social demand for ethical discussion; societal scientific illiteracy; poor social understanding of ethics; a “Gresham’s Law for Ethics;” Scientific Ideology; vested interests dominating ethical discussion. How this can be remedied is discussed.  相似文献

What forms of knowledge are deemed worth possessing in any period and who is allowed access to them are crucial questions for the historian of education. Science, now a core subject of study, has long been seen as ‘masculine’, especially at its highest levels, although the historical reasons for this have been somewhat neglected in education. This paper compares and analyses the interrelationships of education, gender and science at both the end of the long eighteenth century and in the early twentieth century in order to explore issues of knowledge and gender and demonstrate the use of a historical perspective  相似文献

This article aims to analyze how science is discursively attached to certain parts of the world and certain “kinds of people,” i.e., how scientific knowledge is culturally connected to the West and to whiteness. In focus is how the power technology of coloniality organizes scientific content in textbooks as well as how science students are met in the classroom. The empirical data consist of Swedish science textbooks. The analysis is guided by three questions: (1) if and how the colonial history of science is described in Swedish textbooks; (2) how history of science is described; (3) how the global South is represented. The analysis focuses on both what is said and what is unsaid, recurrent narratives, and cultural silences. To discuss how coloniality is organizing the idea of science eduation in terms of the science learner, previous studies are considered. The concepts of power/knowledge, epistemic violence, and coloniality are used to analyze how notions of scientific rationality and modernity are deeply entangled with a colonial way of seeing the world. The analysis shows that the colonial legacy of science and technology is not present in the textbooks. More evident is the talk about science as development. I claim that discourses on scientific development block out stories problematizing the violence done in the name of science. Furthermore, drawing on earlier classroom studies, I examine how the power of coloniality organize how students of color are met and taught, e.g., they are seen as in need of moral fostering rather than as scientific literate persons.  相似文献

Science teachers’ perceptions of affective‐domainobjectives were gathered through interview procedures. A sample of teachers in Western Australian high schools were the subjects of the study.

For the purpose of analysis, a distinction is drawn between attitudes to science (such as ‘enjoyment of science lessons’ and ‘interest in science') and scientific attitudes (such as ‘honesty in reporting data’and ‘tolerance of the views of others').

Analysis of teachers’ views revealed confusion and lack of clarity regarding these science‐related attitudes. However, it is argued that curriculum writers are no clearer in their views.

It is suggested that a much clearer, more explicit justification for attitude objectives (of both kinds) needs to be made by curriculum writers. Science teachers need to be provided with greater assistance in clarifying the role of these attitude objectives, as well as assistance with techniques for their assessment.  相似文献

This study investigated the relations among preservice elementary teachers’ ideas about evolution, their understanding of basic science concepts and college science coursework. Forty-two percent of 240 participants did not accept the theory of human evolution, but held inconsistent ideas about related topics, such as co-existence of humans and dinosaurs and plate tectonics. Accepting the theory of evolution was positively correlated with correctly answering the three other questions related to the age of Earth. Furthermore, participants who rejected evolution scored significantly lower on a test of basic science concepts than did participants who held accurate views on human evolution. Study results revealed no apparent association between completion of advanced college science courses and acceptance of evolutionary theory or understanding of science concepts. Implications for elementary science teacher education were discussed.  相似文献

The article reviews the strikingly divergent viewpoints of intellectuals—scientists and non-scientists—about Science and Technology. It shows that while scientists implicitly accept the difference between Science and Technology, to non-scientists that difference is irrelevant. The most important differences between Science and Technology that lie in their relative scales, outputs and accuracy of predictions are highlighted. The complexity of and difficulty in trying to quantify the contribution of science and technology to economic growth are discussed. Views of science and technology that include their societal perceptions are recommended.  相似文献

Before constructing a new curriculum for any level in integrated‐science education, it is very important to establish a basic philosophy of science teaching which reflects a symbiotic relationship between education and the socio‐economic development in a particular country of the world.

The curriculum structure of integrated‐science education should broaden the basis of curricular decision and should be designated to follow the expectations of the society in providing professional intellectual training so that education can make a significant contribution to the socio‐economic growth of the country. This basic assumption which established a link between cultural and socio‐economic growth, involves a diversification of the cultural trends of science education which must become appropriate to the economic and historical context of each country in a fast changing world of work.

Therefore, by critically removing outside influences in the transmission of scientific knowledge, there should be less uniformity in the context and methods of teaching, and considerable restructuring of education for each country should occur. Thus, considering the historical and geographical differences, a new order in international division of labour would come into being.

In such a hypothesis, a research‐oriented integrated curriculum in science education can play a central role (certainly a better one than in the traditional, discipline‐oriented scheme of science teaching) in obtaining an adequate interaction between scientific education and social problems; this is required for modern cultural and economic development of the world.  相似文献
