This paper focuses on students' ability to transfer modelling performances across content areas, taking into consideration their improvement of content knowledge as a result of a model-based instruction. Sixty-five sixth grade students of one science teacher in an urban public school in the Midwestern USA engaged in scientific modelling practices that were incorporated into a curriculum focused on the nature of matter. Concept-process models were embedded in the curriculum, as well as emphasis on meta-modelling knowledge and modelling practices. Pre–post test items that required drawing scientific models of smell, evaporation, and friction were analysed. The level of content understanding was coded and scored, as were the following elements of modelling performance: explanation, comparativeness, abstraction, and labelling. Paired t-tests were conducted to analyse differences in students' pre–post tests scores on content knowledge and on each element of the modelling performances. These are described in terms of the amount of transfer. Students significantly improved in their content knowledge for the smell and the evaporation models, but not for the friction model, which was expected as that topic was not taught during the instruction. However, students significantly improved in some of their modelling performances for all the three models. This improvement serves as evidence that the model-based instruction can help students acquire modelling practices that they can apply in a new content area. 相似文献

Teachers’ Willingness to Adopt Nature of Science Activities Following a Physical Science Professional Development 总被引：1，自引：0，他引：1
The major science education reform documents emphasize the need for K-12 students to have a robust understanding of nature
of science (NOS), and inservice teachers consequently need to develop their NOS teaching repertoires. This study investigated
the extent to which science teachers were willing to adopt new strategies and activities for teaching NOS in their classrooms.
The participants were 36 elementary, middle, and high school teachers who were completing a year-long physical science professional
development (PD) that included NOS instruction. Data sources consisted of surveys (teachers’ NOS views, teaching practices),
collected work, and responses to post-PD follow-up questions. The professional development course was successful in that teachers
incorporated many of these strategies and activities into their own practice. This study also endeavored to identify factors
that facilitated the adoption of these new approaches to teaching NOS. While personal characteristics such as pre- or post-PD
NOS understandings, NOS gains, and grade level taught were not related to the number of NOS activities incorporated, teachers
from suburban and rural schools were significantly more likely to implement NOS activities. 相似文献

In this paper, we present a professional development/upgrading programme in science for early-years teachers and investigate its impact on the teachers’ competencies in relation to their knowledge and teaching of science. The basic idea of the programme was to motivate the teachers by making them members of an action research group aimed at developing and implementing curriculum activities to which they would contribute and thus meaningfully engaging them in their own learning. The programme used a ‘collaborative partnership’ model for the development of the activities. In this model, the collaborative notion is defined as an act of ‘shared creation’: partners share a goal and members bring their expertise to the partnership. Within this context, the partners were a researcher in science education with a background in physics, who also served as a facilitator, and six in-service early-years teachers with a background in early-years pedagogy and developmental sciences, who had many years of experience (classroom experts). These teachers participated in the programme as co-designers, but were involved to a significantly lesser degree than the researcher. The programme procedures comprised group work and individual teachers’ class work. Data sources included teachers’ essays, field-notes, lesson recordings and group-work records. Data were qualitatively analysed. The main results indicate improvement of teachers’ ‘transformed’ knowledge of the subject matter, development/improvement of knowledge of instructional strategies, including factors related to quality of implementation of the activities, knowledge of the pupils and improvement of the teachers’ efficacy. 相似文献

The challenge of preparing students for the information age has prompted administrators to increase technology in the public schools. Yet despite the increased availability of technology in schools, few teachers are integrating technology for instructional purposes. Preservice teachers must be equipped with adequate content knowledge of technology to create an advantageous learning experience in science classrooms. To understand preservice teachers’ conceptions of technology integration, this research study explored 15 elementary science methods students’ definitions of technology and their attitudes toward incorporating technology into their teaching. The phenomenological study took place in a science methods course that was based on a constructivist approach to teaching and learning science through science activities and class discussions, with an emphasis on a teacher beliefs framework. Data were collected throughout the semester, including an open-ended pre/post-technology integration survey, lesson plans, and reflections on activities conducted throughout the course. Through a qualitative analysis, we identified improvements in students’ technology definitions, increased technology incorporation into science lesson plans, and favorable attitudes toward technology integration in science teaching after instruction. This research project demonstrates that positive changes in beliefs and behaviors relating to technology integration in science instruction among preservice teachers are possible through explicit instruction. 相似文献

Analogies can play a relevant role in students’ learning. However, for the effective use of analogies, teachers should not only have a well-prepared repertoire of validated analogies, which could serve as bridges between the students’ prior knowledge and the scientific knowledge they desire them to understand, but also know how to introduce analogies in their lessons. Both aspects have been discussed in the literature in the last few decades. However, almost nothing is known about how teachers draw their own analogies for instructional purposes or, in other words, about how they reason analogically when planning and conducting teaching. This is the focus of this paper. Six secondary teachers were individually interviewed; the aim was to characterize how they perform each of the analogical reasoning subprocesses, as well as to identify their views on analogies and their use in science teaching. The results were analyzed by considering elements of both theories about analogical reasoning: the structural mapping proposed by Gentner and the analogical mechanism described by Vosniadou. A comprehensive discussion of our results makes it evident that teachers’ content knowledge on scientific topics and on analogies as well as their pedagogical content knowledge on the use of analogies influence all their analogical reasoning subprocesses. Our results also point to the need for improving teachers’ knowledge about analogies and their ability to perform analogical reasoning. 相似文献

This study investigated the effects of a collaborative science intervention on high achieving students’ learning anxiety and attitudes toward science. Thirty‐seven eighth‐grade high achieving students (16 boys and 21 girls) were selected as an experimental group who joined a 20‐week collaborative science intervention, which integrated and utilized an innovative teaching strategy. Fifty‐eight eighth‐grade high achieving students were selected as the comparison group. The Secondary School Student Questionnaire was conducted to measure all participants’ learning anxiety and attitudes toward science. In addition, 12 target students from the experimental group (i.e., six active and six passive students) were recruited for weekly classroom observations and follow‐up interviews during the intervention. Both quantitative and qualitative findings revealed that experimental group students experienced significant impact as seen through increased attitudes and decreased anxiety of learning science. Implications for practice and research are provided. 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

A group of teachers?? meaning-making when they are collaboratively analyzing artifacts from practice in local science classrooms in a school-based professional development (PD) project is examined through repeated interviews and represented as meaning-making maps. The interpretation of the teachers?? meaning-making includes both their reference to outcomes from the project and their expressed ideas about teaching and learning of science. All four teachers refer to experiences from experimenting in their classrooms and interpret the collected artifacts in relation to students?? learning. Furthermore, they all felt encouraged to continue collaboration around science. During the interviews, the teachers emphasize various elements apparently connected to concrete challenges they each experience in their professional work. Implications in relation to the design of PD are discussed. 相似文献

The purpose of this study was to examine changes in the quality of science teachers’ argumentation as a result of their engagement in a teacher workshop on earthquake engineering emphasizing distributed learning approaches, which included concept mapping, collaborative game playing, and group lesson planning. The participants were ten high school science teachers from US high schools who elected to attend the workshop. To begin and end the teacher workshop, teachers in small groups engaged in concept mapping exercises with other teachers. Researchers audio-recorded individual teachers’ argumentative statements about the inclusion of earthquake engineering concepts in their concept maps, which were then analyzed to reveal the quality of teachers’ argumentation. Toulmin’s argumentation model formed the framework for designing a classification schema to analyze the quality of participants’ argumentative statements. While the analysis of differences in pre- and post-workshop concept mapping exercises revealed that the number of argumentative statements did not change significantly, the quality of participants’ argumentation did increase significantly. As these differences occurred concurrently with distributed learning approaches used throughout the workshop, these results provide evidence to support distributed learning approaches in professional development workshop activities to increase the quality of science teachers’ argumentation. Additionally, these results support the use of concept mapping as a cognitive scaffold to organize participants’ knowledge, facilitate the presentation of argumentation, and as a research tool for providing evidence of teachers’ argumentation skills. 相似文献

This study investigated high school students’ conceptions of technology-assisted science learning via drawing analysis, and explored how students with different degrees of computer experience and science learning self-efficacy may show different conceptions via their drawings. The participants included 335 senior high school students in Taiwan (179 male and 156 female). All of them were asked by guiding questions to make two drawings to represent their conceptions of technology-assisted science learning in actual and ideal contexts, respectively. Their background information including computer experience and science learning self-efficacy were obtained using self-reported questionnaires. Through drawing analysis, seven categories of conceptions of technology-assisted science learning were identified, including types of technology, location of learning, types of learning activities, content of learning, participants of learning activities, affordance of learning technology, and effects of learning technology. The results further revealed that the students’ conceptions of actual and ideal technology-assisted science learning significantly differed in some sub-categories of all categories except the category of participants of learning activities. Moreover, students’ computer experience and science learning self-efficacy may link to different conceptions of technology-assisted science learning. Future research and directions are also discussed.

Abstract The reasons why girls avoid science subjects were studied by comparing three groups of girls and three groups of boys in the Norwegian secondary school who opted for physics, biology/chemistry and non‐science subjects, respectively. On the basis of documented data on their level of attainment in science subjects, and questionnaire data on confidence in science achievement, attitudes towards the sciences and job priorities, the “hard’ science girls proved to be more confident and laid more stress upon income and leadership than the other groups of girls. No differences between the groups’ attitudes towards science were found. The ‘hard’ science group of girls performed better than the boys in the science subjects and they stressed the importance of income in their future job as much as did the boys. These findings suggest that girls make rational educational choices based on their perception of their own aptitude for science and on their future occupational plans. 相似文献

The purpose of this study was to describe the influence of constructivist classroom contextual factors in a life science laboratory
and a traditional science classroom on elementary students’ motivation and learning strategy use. The Constructivist Teaching
Inventory was used to examine classroom contextual factors. The Motivated Strategies for Learning Questionnaire was used to
examine student motivation and learning strategies. A Wilcoxon nonparametric test determined that constructivist teaching
practices were found to occur more often in the life laboratory than in the regular classroom. Although constructivist teaching
practices increased at each observation time in both the regular classroom and in the life laboratory, a Friedman test determined
that they were not statistically significant increases. Paired sample t tests determined that student motivation and learning
strategies were higher in the life laboratory than in the regular classroom overall as well as at each survey time except
for learning strategies at Post 1. A 2 × 4 between 3 within repeated measure ANOVA determined that student MSLQ motivation
and learning strategy scores in the regular classroom varied statistically significantly by teacher. Student MSLQ motivation
and learning strategy scores in the life laboratory varied statistically significantly by teacher. To triangulate data, individual
interviews of students were conducted at the end of the semester and revealed students regard the life laboratory as an asset
to their science study; however, students do appreciate and value working in the learning environment that the regular classroom
provides. 相似文献

Study provides qualitative analysis of data that answers the following research question: how college science faculty teach science and NOS and incorporate aspects of NOS and the history of science into their undergraduate courses? Study concentrates on four cases and more specifically on three introductory science classes and on four instructors who taught those courses. These instructors were chosen as case studies to explore in greater detail what occurs inside introductory science courses in one particular higher institution in the Northeastern United States. Participants’ teaching styles are presented through a combined and detailed presentation of interview data and classroom observations supported with examples from their classroom activities. Constant comparative approach was used in the process of organizing and analyzing data. Findings revealed that participants preferred to use the traditional teacher-centered lecturing as their teaching style and whose main concern was to cover more content, develop the problem solving skills of their students, and who wanted to teach the fundamental principles of their subjects without paying special importance to the NOS aspects. The study also revealed that other variables of teaching science, such as large class size, lack of management and organizational skills, teaching experience, and instructors’ concerns for students’ abilities and motivation are more important for these scientists then teaching for understanding of NOS. 相似文献

The 39 preservice teachers (PSTs) who participated in this study were enrolled in a masters program for secondary science teacher certification. Initially they held broad ideas about teaching and learning gleaned from their own experiences. Guided by the program course work, some PSTs embraced the pedagogical approaches introduced in the program, applied them in their teaching, and reflected on the outcomes. Their reflections showed that they were focused on keeping all of their students interested in science and on student participation in the process of meaning-making. Some PSTs embraced the program goals but struggled to achieve them in teaching. Others focused on transmission of content and did not attempt to develop an environment of student agency. There were nine career-changer PSTs and most of them remained teacher-centered throughout the program. The implications of student- and teacher-centered approaches adopted by the PSTs and the rationales provided by them are discussed in the paper. 相似文献

The study reported here investigated experienced teachers’ views on several nature of science (NOS) issues 2 to 5 years after they completed a demanding secondary science teacher education program in which the NOS was an extensive and recurring component. Both quantitative and qualitative data were collected and analyzed to determine study participants’ NOS understanding. Study participant’s NOS views were determined to be generally accurate and robust, suggesting that experiences in their science teacher education program had a long-lasting positive impact on NOS understanding. The preservice program that study participants completed has several unique features that may account for that long-lasting impact and has implications for preservice and inservice science teacher education professional development. 相似文献
