STS与基础科学教育   总被引:5,自引:0,他引:5  
在各种的教育改革方案里,对于STS内容越来越多的引进,已成为一种趋势。然而,联系到我国目前教育界和学术界的现状,对有关的问题仍缺乏必要的了解和深入研究。根据若干国外的科学教育标准进行比较研究,关注的是在其中STS观念与内容的体现,以及在不同方案中表现出来的特点与差异,我们可以理解STS对于基础科学教育已经产生的影响,看到我国基础科学教育与国际相比较显示出的差距,从而对当前的认识与未来的发展都有重要的意义和借鉴作用。  相似文献

An important objective in science education is for students to understand the nature of science. Therefore, it is important that science textbooks, which are key resources in elementary science curricula, convey an accurate conception of the nature of science. This study examined first- to fifth-grade elementary science textbooks with regard to their presentations of the nature of science.  相似文献

This study explored whether early childhood preservice teachers' concerns about teaching nature of science (NOS) and their intellectual levels influenced whether and how they taught NOS at the preschool and primary (K‐3) levels. We used videotaped classroom observations and lesson plans to determine the science instructional practices at the preschool and primary levels, and to track whether and how preservice teachers emphasized NOS. We used the Stages of Concern Questionnaire (SOCQ) pre‐ and postinternship to determine concerns about NOS instruction, and the Learning Context Questionnaire (LCQ) to determine intellectual levels. We found that neither concerns about teaching NOS nor intellectual level were related to whether and how the preservice teachers emphasized NOS; however, we found that all preservice early childhood teachers began their internships with NOS concern profiles of “worried.” Two preservice teachers' NOS concerns profiles changed as a result of their internships; one to “cooperator” and one to “cooperator/improver.” These two preservice teachers had cooperating teachers who were aware of NOS and implemented it in their own science instruction. The main factors that hindered or facilitated teaching NOS for these preservice teachers were the influence of the cooperating teacher and the use of the science curriculum. The preservice teacher with the cooperating teacher who understood and emphasized NOS herself and showed her how to modify the curriculum to include NOS, was able to explicitly teach NOS to her students. Those in classrooms whose cooperating teachers did not provide support for NOS instruction were unable to emphasize NOS. © 2009 Wiley Periodicals, Inc. J Res Sci Teach 47:213–233, 2010  相似文献

There are many factors influence the level of students' achievement in education. Studies show that one of these factors is "learning approach of a student". Research findings generally have identified two approaches of learning: deep and surface. When a student uses the deep approach, he/she has an intrinsic interest in subject matter and is interested in ideas and conclusions to understand the subject matter. When a student employs the surface approach, he/she merely memorizes knowledge to pass any exam in school. The aim of this study is to determine learning approaches of science student teachers and to examine the relationships among the variables, such as level of students' class and gender. The sample of this study consists of 108 student teachers from the Science Education Program at Department of Primary Science Education in Karadeniz Technical University. Approaches to learning of science student teachers are assessed using the Revised Two-factor Study Process Questionnaire (R-SPQ-2F), a scale developed by Biggs, et al (2001) consisting of 20 items on a 5 point Likert Scale. According to findings, science student teachers generally have deep learning approaches. Moreover, learning approaches of science student teachers have not changed related to gender.  相似文献

Many science education programs have recently been developed to increase girls' participation in science, however, few formal evaluations of these types of programs have been reported. The present research evaluated fifth grade girls' perceptions of a 1-day science education program. Students attended workshops describing different science fields. Study 1 revealed that attending the workshops increased students' interest in the specific field covered in the workshop. However, even after attending the workshops, students did not believe women typically entered those various fields. A second year evaluation revealed that most students agreed they had learned about individual tasks that scientists do in the various fields. However, significantly fewer believed they learned about educational requirements, problems women might face in the field, or how science can be used to help people. Results are discussed in terms of potential factors that workshop presenters might want to consider in future programs.  相似文献

ABSTRACT

We first examined the effects of a year-long professional development (PD) programme for elementary science teachers on fifth grade student performance on state-mandated science achievement tests of students from a treatment and a comparison group of teachers in the 2009–2010 academic year. Then, we investigated the longer-term impacts by comparing the 2010–2011 student test results of the teachers one year after receiving treatment in 2009–2010 with the students of teachers who received treatment during 2010–2011. Test scores were analysed using a propensity score matching method to examine the relationship between the PD and student achievement. Results showed that even though the treatment teachers were out of the classroom 20% of the school year to attend the PD, there was no difference between their students’ science achievement scores and those of the comparison teachers who were in the classroom every day. This is an important finding because many principals and parents are reluctant to provide teachers with release time for PD. We also determined that students of teachers one year after participating in the PD significantly (p?<?0.001) with a medium effect size (η2?=?.088) outperformed students of teachers who had just completed the programme. This suggests that it takes time for teachers to implement new teaching strategies and that to observe the impact of an intervention programme, it may be important to expand the timeframe of the programme evaluation.  相似文献

This paper reports on a two year study designed to investigate how a Web-Based Integrated Science Environment (WISE) project called Plants in Space featuring classroom investigations can enable fifth grade students to increase their understanding of plant growth and development. A multidisciplinary partnership consisting of teachers, scientists, science education researchers, and technology specialists developed this project, tested it in fifth grade, modified it based on the data collected in year one and tested it again. We investigate these two versions of the curriculum and consider how understanding of the material improved with the revised curriculum.Participants were fifth grade students and a fifth grade teacher who was a co-developer of the curriculum and participated in the re-design process at an urban elementary school. An identical pre- and a post-subject matter assessment was administered to all students each year. Interviews and students' in-class work helped clarify the results. Overall, students made significant gains in understanding standards-based science concepts including photosynthesis.  相似文献

ABSTRACT

This qualitative study explored elementary teachers’ perceptions about the effective features of explicit-reflective nature of science (NOS) instruction. Our participants were four elementary teachers from a public charter school located in the Southwestern U.S.A. The four elementary teachers participated in an academic year-long professional development about NOS which consisted of NOS training and NOS teaching phases. After each phase of the professional development, we specifically asked our participants which features of the explicit-reflective NOS instruction they found effective in improving their NOS conceptions by presenting pre- and post-profiles of their NOS conceptions. We identified nine features perceived by the participants as effective components of explicit-reflective NOS instruction: (1) specific focus on NOS content, (2) participation in hands-on NOS activities, (3) introductory NOS readings, (4) multiple types/forms of reflection, (5) multiple exposure to NOS content, (6) structural consistency in the presentation of NOS content, (7) the evaluation of secondary NOS data from elementary students, (8) the analysis of national and state science standards in terms of NOS content, and (9) NOS teaching experience.  相似文献

This study investigated the effect of including explicit nature of science (NOS) content in read-alouds of elementary science trade books on the teaching and learning of NOS. We focused on three aspects of NOS: the creative, the empirical, and the inferential NOS. The trade books were read aloud by teachers in three hierarchical levels: Level I served as a control and consisted of a trade book that remained unmodified, Level II consisted of a trade book that had been modified to include explicit references to NOS, and Level III consisted of a modified trade book accompanied by educative curriculum materials that were aimed at improving the teachers' views of NOS as well as supporting teaching about NOS. We used the Views of Nature of Science Questionnaire-form CE (VNOS-CE) preintervention and postintervention to determine changes in teachers' views of NOS and interviews preintervention and postintervention to determine changes in students' views. Audio recordings of read-alouds were used to determine changes in teaching practice, including the frequency and the quality (i.e., naïve or informed) of the NOS references in the discussions. Interviews were used to determine teachers' perceptions of the modified trade books and educative curriculum materials. We found that both teachers and students developed more informed views of the targeted NOS aspects after the intervention and that teachers addressed NOS more often, and in a more informed manner, when they had trade books that explicitly supported NOS instruction and educative curriculum materials that supported their learning about NOS. Furthermore, they perceived the intervention materials favorably. Teachers' views and practices were able to change in tandem because of the intervention materials that supported explicit NOS instruction. We highlight the need for more widespread development of similar educative curriculum materials.  相似文献

The professional development project reported on in this paper, the Beginning Elementary Science Teachers' (BEST) project, was based on the premise that the first years of elementary science teaching can be very important in the development of long-term quality science teaching. Specifically, we report on project experiences that allowed 13 beginning teachers to interact with experienced teachers in a university seminar and during school visits. Results show that these limited mentoring experiences can support the development of professional knowledge and discussion centers on factors that facilitate knowledge growth. Conclusions are presented that compare benefits of these limited mentoring experiences to those reported to be achieved in long-term mentoring programs.  相似文献

New reform documents underscore the importance of integrating science practices into the learning of science. This integration requires sophisticated teaching that does not often happen. Educative curriculum materials – materials explicitly designed to support teacher and student learning – have been posited as a way to support teachers to achieve these ambitious goals, yet little is known about how elementary teachers actually use educative curriculum materials to support student engagement in science practices. To address this gap, this study investigated how five upper elementary teachers supported students to engage in science practices during an enactment of two curriculum units. Three of the teachers had units enhanced with educative features, informed by current research and reforms, while two of the teachers had units without these features. The teachers varied in how they supported students in the science practices of justifying predictions, constructing evidence-based claims, recording observations, and planning investigations. For example, some of the teachers with the educative features supported students in constructing evidence-based claims and justifying predictions in ways called for by the educative features. Implications for curriculum developers and teacher educators are discussed based on the patterns found in the teachers’ use of the educative curriculum materials.  相似文献

The science achievement of 226 5th graders from districts that have a kit-based inquiry science curriculum supported by intensive professional development (PD) is compared with data from a group of 173 5th graders from other districts that use nonkit science materials and do not have systematic science PD for teachers. Within the kit-based project, the sample of project teachers is stratified to select teachers with a high number of science PD hours versus those with few hours. While there were no significant differences in the mean total scores for kit-based students with low PD versus high PD teachers, the kit-based classrooms scored significantly higher than students in nonkit classrooms on both the pretest and posttest, though there were significantly more minutes of science instruction in the nonkit classrooms. Finally, nonkit teachers taught more units of shorter length and reported lower levels of preparedness to use reform pedagogical approaches.  相似文献

This article describes the development of a questionnaire to discover primary school students’ perceptions of science, religion and the relationships between them on a range of topics that are known as Big Questions. The questionnaire was administered in 16 primary schools in England with over 750 students aged 10–11. The findings indicate that students in this age group have begun to consider how science and religion relate and that while there is a diversity of positions, a significant proportion perceived science and religion to conflict. Analysis of responses also indicated that primary school students’ epistemic insight was limited in relation to their understanding of the nature of science and, in particular, the idea that science has limitations. The basis and potential consequences of such views are considered and recommendations for teaching practice are presented, together with ideas for future research. It is anticipated that the study will inform teachers and curriculum planners developing approaches and guidance materials in science and religious education.  相似文献

Issues regarding scientific explanation have been of interest to philosophers from Pre-Socratic times. The notion of scientific explanation is of interest not only to philosophers, but also to science educators as is clearly evident in the emphasis given to K-12 students' construction of explanations in current national science education reform efforts. Nonetheless, there is a dearth of research on conceptualizing explanation in science education. Using a philosophically guided framework—the Nature of Scientific Explanation (NOSE) framework—the study aims to elucidate and compare college freshmen science students', secondary science teachers', and practicing scientists' scientific explanations and their views of scientific explanations. In particular, this study aims to: (1) analyze students', teachers', and scientists' scientific explanations; (2) explore the nuances about how freshman students, science teachers, and practicing scientists construct explanations; and (3) elucidate the criteria that participants use in analyzing scientific explanations. In two separate interviews, participants first constructed explanations of everyday scientific phenomena and then provided feedback on the explanations constructed by other participants. Major findings showed that, when analyzed using NOSE framework, participant scientists did significantly “better” than teachers and students. Our analysis revealed that scientists, teachers, and students share a lot of similarities in how they construct their explanations in science. However, they differ in some key dimensions. The present study highlighted the need articulated by many researchers in science education to understand additional aspects specific to scientific explanation. The present findings provide an initial analytical framework for examining students' and science teachers' scientific explanations.  相似文献
