Although understandings of scientific inquiry (as opposed to conducting inquiry) are included in science education reform documents around the world, little is known about what students have learned about inquiry during their elementary school years. This is partially due to the lack of any assessment instrument to measure understandings about scientific inquiry. However, a valid and reliable assessment has recently been developed and published, Views About Scientific Inquiry (VASI; Lederman et al. [2014], Journal of Research in Science Teaching, 51, 65–83). The purpose of this large-scale international project was to collect the first baseline data on what beginning middle school students have learned about scientific inquiry during their elementary school years. Eighteen countries/regions spanning six continents including 2,634 students participated in the study. The participating countries/regions were: Australia, Brazil, Chile, Egypt, England, Finland, France, Germany, Israel, Mainland China, New Zealand, Nigeria, South Africa, Spain, Sweden, Taiwan, Turkey, and the United States. In many countries, science is not formally taught until middle school, which is the rationale for choosing seventh grade students for this investigation. This baseline data will simultaneously provide information on what, if anything, students learn about inquiry in elementary school, as well as their beginning knowledge as they enter secondary school. It is important to note that collecting data from all of the approximately 200 countries globally was not humanly possible, and it was also not possible to collect data from every region of each country. The results overwhelmingly show that students around the world at the beginning of grade seven have very little understandings about scientific inquiry. Some countries do show reasonable understandings in certain aspects but the overall picture of understandings of scientific inquiry is not what is hoped for after completing 6 years of elementary education in any country.  相似文献

Much is known about high school students’ attitudes towards science but there is almost no research on what passion for science might look like and how it might be manifested. This exploratory case study took advantage of a unique group of highly gifted science students participating in the Australian Science Olympiad (N = 69) to explore their attitudes towards school science and science as presented in the Olympiad summer camp. In particular the role the summer camp might play in igniting the students’ passion for science was a focus of the research. Data were collected through a two-tiered survey of students’ attitudes towards school science, an evaluative survey of the Olympiad summer camp and in-depth interviews with six participants. Findings indicated that Olympiad students generally had positive attitudes towards school science with most selecting science as one of their favourite subjects. However, an underlying ambivalence about school science was noted in the data. In contrast, the Olympiad summer camp transformed students’ positive attitudes into passion for science. Seven themes emerged from the data providing a foundation for a model of what academic passion for science looks like.  相似文献

In recent decades, a consensus has emerged among educators and scientists that all compulsory school students need good science education. The debate about its purpose and nature as a school subject in an emerging information society has not been as conclusive. To further understand this, it helps to examine how the science curriculum has transformed and what forces have shaped it as a core curricular area over time. This article sheds light on the transformation of the science curriculum for compulsory schools in Iceland in force from 1960 to 2010. Using criteria based on curriculum ideologies regarding the function of learners, instructors and subject matter in the learning process and the orientation of content and product versus process and development, it offers findings from content analysis of the intended science curriculum. The official curriculum was studied and conceptualised as it has evolved over time. The curriculum developers appear to have been striving for a compromise between conflicting views, resulting in what the authors of this article conceive as a ‘kaleidoscopic quilt’ of ideas over the period studied.  相似文献

Background: Research has primarily concentrated on adults’ implicit theories about high quality science education for all students. Little work has considered the students’ perspective. This study investigated high school students’ implicit theories about what helped them learn science.

Purpose: This study addressed (1) What characterizes high school students’ implicit theories of what facilitates their learning of science?; (2) With respect to students’ self-classifications as African American or European American and female or male, do differences exist in the students’ implicit theories?

Sample, design and methods: Students in an urban high school located in south-eastern United States were surveyed in 2006 about their thoughts on what helps them learn science. To confirm or disconfirm any differences, data from two different samples were analyzed. Responses of 112 African American and 118 European American students and responses from 297 European American students comprised the data for sample one and two, respectively.

Results: Seven categories emerged from the deductive and inductive analyses of data: personal responsibility, learning arrangements, interest and knowledge, communication, student mastery, environmental responsiveness, and instructional strategies. Instructional strategies captured 82% and 80% of the data from sample one and two, respectively; consequently, this category was further subjected to Mann-Whitney statistical analysis at p < .05 to ascertain ethnic differences. Significant differences did not exist for ethnicity but differences between females and males in sample one and sample two emerged.

Conclusions: African American and European American students’ implicit theories about instructional strategies that facilitated their science learning did not significantly differ but female and male students’ implicit theories about instructional strategies that helped them learn science significantly differed. Because students attend and respond to what they think and perceive to be important, addressing students’ implicit theories may be one way to enhance science education reform.  相似文献

Recent efforts of the National Association for Research in Science Teaching (NARST) and the National Science Teachers Association (NSTA) have encouraged collaborative “research partnerships” between university researchers and classroom science teachers. This research partners study, begun in 1987, examined student outcomes and teacher characteristics in middle/junior high exemplary programs identified by the NSTA's Search for Excellence in Science Education (SESE). A second year of the study has been completed involving SESE program teachers with similar instructional profiles. Using Iowa Test of Basic Skills and National Assessment of Educational Progress (NAEP) items, key teachers in those SESE programs examined their seventh- and eighth-grade student outcomes in three domains: (a) knowledge, (b) attitudes, and (c) applications/connections. Results were compared with national populations. A similar study was conducted during the second year, involving teachers from the first year and additional teachers with instructional practice profiles similar to those in SESE programs. Teachers were surveyed using a questionnaire from the Report of the 1977 National Survey of Science, Mathematics and Social Studies Education Teachers (Weiss, 1978a) and supplemental questions (Bonnstetter, 1985). This study found that in exemplary middle/junior high programs: (a) as a group, students achieve high scores in science knowledge and maintain or develop positive attitudes toward science; and (b) students need opportunities to make connections between what they learn in science and personal responsibility.  相似文献

Participation in inquiry-based science education, which focuses on student-constructed learning, has been linked to academic success. Whereas the benefits of this type of science education are evident, access to such high-quality science curriculum and programming is not equitable. Black and Latino students in particular have less access to supplementary science programming, and fewer opportunities to engage in inquiry-based education. This paper describes outcomes associated with an inquiry-based out-of-school time science education program, Nuestro Futuro: Applied Science Education to Engage Black and Latino Youth (NFASE), which sought to build the capacity of middle school students of color to ‘think’ like health scientists from diverse disciplinary perspectives. The program was designed with the intent of (1) improving student attitudes toward and motivation for science and (2) increasing active and engaged citizenship (AEC). NFASE students explored health inequity and the social determinants of health locally and engaged in developing health promotion, outreach and education efforts targeted to their peers, parents/families, and community. Interest in the program was high overall, but implementation was not without challenges. Although evaluation outcomes indicate that there were no statistically significant changes in science-related attitudes or motivation, students reported significant increases in neighborhood social connection, as well as overall AEC.  相似文献

From a sociocultural perspective, I discuss data from a Swedish science classroom presented in María Gómez’s article “Student Explanations of their Science Teachers’ Assessments, Grading Practices, and How they learn Science”. In this discussion, I focus on the need to change existing conceptions of assessment in the teaching and learning of science. Next, I talk about the importance of taking into consideration the dialectic between agency and passivity as filters in order to understand what student silence may signify in science classes as well as in relation to their perceptions of assessment. I conclude with the importance of the teacher’s role in developing formative assessment, along with the challenges in developing assessments which transform science education into a relevant field of knowledge for both students and society at large.  相似文献

The transfer of matter and energy from one organism to another and between organisms and their physical setting is a fundamental concept in life science. Not surprisingly, this concept is common to the Benchmarks for Science Literacy (American Association for the Advancement of Science, 1993 ), the National Science Education Standards (National Research Council, 1996 ), and most state frameworks and likely to appear in any middle‐school science curriculum material. Nonetheless, while topics such as photosynthesis and cellular respiration have been taught for many years, research on student learning indicates that students have difficulties learning these ideas. In this study, nine middle‐school curriculum materials—both widely used and newly developed—were examined in detail for their support of student learning ideas concerning matter and energy transformations in ecosystems specified in the national standards documents. The analysis procedure used in this study was previously developed and field tested by Project 2061 of the AAAS on a variety of curriculum materials. According to our findings, currently available curriculum materials provide little support for the attainment of the key ideas chosen for this study. In general, these materials do not take into account students' prior knowledge, lack representations to clarify abstract ideas, and are deficient in phenomena that can be explained by the key ideas and hence can make them plausible. This article concludes with a discussion of the implications of this study to curriculum development, teaching, and science education research based on shortcomings in today's curricula. © 2004 Wiley Periodicals, Inc.

This study explores middle school students’ aspirations in science, technology, engineering, and medical (STE-M) careers by analyzing survey data during their eighth and ninth grade years from an ethnically and economically diverse sample of Southern California urban and suburban public school students (n = 493). Students were classified based on their responses to questions about their science ability beliefs and subjective task values using latent class analysis (LCA). Four distinct groups of students were identified: Science is Me; I Value Science But Don’t Do It Well; I Can Do Science but I Don’t Value It Highly; and Science is Not Me. Few students (22 %) were classified as having strong science ability beliefs, and only a third as strongly valuing learning/doing science; a majority (57 %) were in the Science is Not Me category, underscoring the scope of the challenge to invite more young people to want to learn science. As predicted, students who believed they could do science and valued science were more likely than others to indicate interest in STE-M careers. This relationship between perceptions and aspirations was true regardless of gender, ethnicity, and type of STE-M field, but varied depending on socioeconomic status. Using LCA to organize information about students’ science self-perceptions may help target specific interventions to student interests and aspirations and better support and encourage their persistence in STE-M careers.  相似文献

This qualitative, multi-case study explored the use of science-content music for teaching and learning in six middle school science classrooms. The researcher sought to understand how teachers made use of content-rich songs for teaching science, how they impacted student engagement and learning, and what the experiences of these teachers and students suggested about using songs for middle school classroom science instruction. Data gathered included three teacher interviews, one classroom observation and a student focus-group discussion from each of six cases. The data from each unit of analysis were examined independently and then synthesized in a multi-case analysis, resulting in a number of merged findings, or assertions, about the experience. The results of this study indicated that teachers used content-rich music to enhance student understanding of concepts in science by developing content-based vocabulary, providing students with alternative examples and explanations of concepts, and as a sense-making experience to help build conceptual understanding. The use of science-content songs engaged students by providing both situational and personal interest, and provided a mnemonic device for remembering key concepts in science. The use of songs has relevance from a constructivist approach as they were used to help students build meaning; from a socio-cultural perspective in terms of student engagement; and from a cognitive viewpoint in that in these cases they helped students make connections in learning. The results of this research have implications for science teachers and the science education community in developing new instructional strategies for the middle school science classroom.  相似文献

This study used a Chinese-language version of the Index of Science Reading Awareness to explore the science reading metacognition and comprehension of Taiwanese students. Structural equation modelling results confirmed the underlying model comprised three clusters of metacognitive knowledge: beliefs and confidence in science reading, knowledge of structure of science text, and knowledge of science reading strategies. The main contribution of the current research was to provide evidence about the relationship between metacognitive awareness and comprehension of science text. In addition, data comparisons to Canadian (British Columbia) benchmarks from the original development revealed that metacognitive awareness of science reading deteriorated from elementary to middle school in both countries, and there were no significant differences of metacognitive awareness of science reading between Canadian and Taiwanese students. Instructional suggestions for raising students' metacognitive awareness on science reading were discussed.  相似文献

We report on the construction and application on an instrument entitled the “Science Achievement Influences Survey” to assess combined effects of student attitudes about science, peer interaction, and home support, and the frequency of student‐centred and teacher‐centred instructional practices on student achievement. Controlling for pre‐test content knowledge, results indicated that student‐centred teaching practices have a positive association with student achievement (p < .01; i.e., group experiments) and a negative association with teacher‐centred teaching practices (p < .01; i.e., copying notes). Additionally, student attitudes about science were positively associated with student‐centred teaching practices (p < .01) and negatively associated with teacher‐centred teaching practices (p < .01). Most significantly, this study documents the predicted gains in science achievement associated with frequency of specific instructional practices used by middle‐school science teachers. Especially noteworthy and significant is the finding that near‐daily implementation of group experiments and reduction of extensive note‐copying during class yield the greatest positive impact on student achievement. Outside of school, peer interaction and home support were not significantly associated (p > .05) with student achievement. The student sample included 611 middle‐school science students with a wide range of socioeconomic and cultural backgrounds.  相似文献

Although there is universal consensus both in the science education literature and in the science standards documents to the effect that students should learn not only the content of science but also its nature, there is little agreement about what that nature is. This led many science educators to adopt what is sometimes called ??the consensus view?? about the nature of science (NOS), whose goal is to teach students only those characteristics of science on which there is wide consensus. This is an attractive view, but it has some shortcomings and weaknesses. In this article we present and defend an alternative approach based on the notion of family resemblance. We argue that the family resemblance approach is superior to the consensus view in several ways, which we discuss in some detail.  相似文献

To a science ‘outsider’, science language often appears unnecessarily technical and dense. However, scientific language is typically used with the goal of being concise and precise, which allows those who regularly participate in scientific discourse communities to learn from each other and build upon existing scientific knowledge. One essential component of science language is the academic vocabulary that characterises it. This mixed-methods study investigates middle school students’ (N?=?59) growth in academic vocabulary as it relates to their teacher’s instructional practices that supported academic language development. Students made significant gains in their production of general academic words, t(57)?=?2.32, p?=?.024 and of discipline-specific science words, t(57)?=?3.01, p?=?.004 in science writing. Results from the qualitative strand of this inquiry contextualised the students’ learning of academic vocabulary as it relates to their teacher’s instructional practices and intentions as well as the students’ perceptions of their learning environment. These qualitative findings reveal that both the students and their teacher articulated that the teacher’s intentional use of resources supported students’ academic vocabulary growth. Implications for research and instruction with science language are shared.  相似文献

This report presents pilot-test results for a science professional development program featuring online, on-demand materials developed by the National Science Teachers Association. During the spring 2006 semester, 45 middle school teachers from three different school districts across the United States participated in a professional development program designed to facilitate content knowledge and skills in the area of Newtonian force and motion. Participants from one of the school districts experienced a full-day instructor-led workshop along with two web-based seminars with a content-area expert. This was followed by a 4-week period of time in which they had access to self-directed, online, on-demand instructional materials that included activities, information, simulations, examples, and practice with immediate feedback over the targeted outcomes. Participants from the two other school districts only had access to the online materials with no instructor-led experience. This report documents positive gains in achievement as well as levels of confidence in teaching the material within all of the professional development groups. Data about the use of specific features within the online material are included, as well as completion rates and attitude survey results. Recommendations for future study are also included.  相似文献

This study investigated ways to foster positive science attitudes among newcomer first-year middle school English learners (n?=?79) under two conditions: (1) Extended Science?+?Extended Literacy (planetarium-based visualisations?+?vocabulary?+?comic and trade books) and (2) Extended Science?+?Literacy (planetarium-based visualisations?+?vocabulary). The results indicated a statistically and practically meaningful increase in science attitudes (Cohen’s d?=?0.43) after an 8-week science unit delivered under the Extended Science?+?Extended Literacy condition, which was maintained, but not increased, for the second 8-week unit under the Extended Science?+?Literacy condition. These results suggest that the combination of planetarium-based visualisations and comic and trade books can be effective for supporting newcomer ELs’ science attitudes. However, once achieved, this effect may be maintained with less intensive literacy (vocabulary only) support. Student judgments of the quality of the planetarium-based visualisation experiences in terms of clarity, easiness, excitement, and usefulness began high and went even higher with more experiences, Cohen’s d?>?0.50 for three out of four quality indicators. Interviews corroborated these results with teacher and students indicating that they highly valued the visually-rich nature of the program, the variety of learning opportunities within the program, and program continuity/close alignment between science and literacy supports—all components contributing to high levels of engagement and positive attitudes toward science. Ways to adopt program components across settings are discussed.  相似文献
