In the context of the emphasis on inquiry teaching in science education, this study looks into how pre-service elementary
teachers understand and practise science inquiry teaching during field experience. By examining inquiry lesson preparation,
practice, and reflections of pre-service elementary teachers, we attempt to understand the difficulties they encounter and
what could result from those difficulties in their practice. A total of 16 seniors (fourth-year students) in an elementary
teacher education program participated in this study. In our findings, we highlight three difficulties ‘on the lesson’ that are related to teaching practices that were missing in the classrooms: (1) developing children’s own ideas and curiosity,
(2) guiding children in designing valid experiments for their hypotheses, (3) scaffolding children’s data interpretation and
discussion and another three difficulties ‘under the lesson’ that are related to problems with the pre-service teachers’ conceptualization of the task: (4) tension between guided and
open inquiry, (5) incomplete understanding of hypothesis, and (6) lack of confidence in science content knowledge. Based on
these findings, we discuss how these difficulties are complexly related in the pre-service teachers’ understandings and action.
Several suggestions for science teacher education for inquiry teaching, especially hypothesis-based inquiry teaching, are
then explored. 相似文献

This study investigated teachers’ motivation, expectations, and changes to teaching practices due to a 6 week summer professional
development program involvement. Participants (n = 67) attended the Research Experiences for Teachers (RET) program within a major university in southeast. Surveys and interviews
were used to collect data to answer the following research questions: (1) Who attends the RET program? (2) In what ways do
elementary teachers differ from middle/secondary teachers with respect to their motivation for attending the RET program and
their expectations about the program? (3) In what ways do elementary teachers differ from middle/secondary teachers with respect
to implementing changes to their teaching practices due to RET program attendance? Survey results indicated significant differences
between elementary teachers and secondary education teachers with respect to their expectations about the program, and changes
to their teaching practices. Interview results provided support to survey findings. Implications for professional development
and science teacher education are discussed in relationship with the current study findings. 相似文献

This self-study examined the 1st-year science teacher educator's integration of instructional technology into a science methods
course and modeled the reflective practice of her own teaching. Elementary science methods students participated in a series
of inquiry-based activities that utilized various instructional technologies. Data sources included daily reflections, formative
assessments, concern-based surveys, and class assignments. Findings from this self-study revealed that the teacher educator's
own reflections and practical inquiry influenced and paralleled her students’ development of learning how to teach scientific
inquiry using instructional technology. Results suggest that inviting preservice teachers into reflective practice and modeling
for them the development of professional practical knowledge allow them to address the uncertainties in their own learning
about using technology for inquiry-based science teaching. 相似文献

Given the high attrition rate of beginning science teachers, it is imperative to better prepare science preservice teachers,
so that they can be successful during the early years of their teaching. The purpose of this study was to explore science
preservice teachers’ views of themselves as a future teacher, in particular their hopes and fears for science teaching and
the experiences that help to shape their possible selves. Employed were qualitative methods, which included open-ended surveys
and face-to-face interviews. Eleven preservice teachers who enrolled in a secondary science teacher preparation program participated.
Findings showed six categories of future selves with the most frequent category being for effective/ineffective science teaching.
When their hoped-for and feared selves were not balanced, participants articulated more fears. Regarding the primary influence
in shaping their hopes and fears, diverse past experiences related to teaching and learning appeared to be more salient factors
than science teacher education program. Given the enriched understanding of the science preservice teachers’ perceptions,
we provided suggestions for science teacher educators. 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

This case study of a fifth-year elementary intern’s pathway in learning to teach science focused on her science methods course,
placement science teaching, and reflections as a first-year teacher. We studied the sociocultural contexts within which the
intern learned, their affordances and constraints, and participants’ perspectives on their roles and responsibilities, and
her learning. Semi-structured interviews were conducted with all participants. Audiotapes of the science methods class, videotapes
of her science teaching, and field notes were collected. Data were transcribed and searched for affordances or constraints
within contexts, perspectives on roles and responsibilities, and how views of her progress changed. Findings show the intern’s
substantial progress, the ways in which affordances sometimes became constraints, and participants’ sometimes contradictory
perspectives. 相似文献

In this paper we present findings from a project that documented the development of preservice teachers’ beliefs and practices in delivering science instruction that considers issues of language and culture. Teacher candidates in the intervention group (n = 65) received a science methods course and teaching practicum experience that provided guidance in teaching science in culturally and linguistically responsive ways. Comparisons between a control group of preservice teachers (n = 45) and those involved in the intervention yielded stronger beliefs about the efficacy in promoting collaboration in science teaching than the intervention group. Observations of these preservice teachers during their teaching practicum revealed differences in favor of the intervention group in: (a) implementing science instruction that addressed the language and literacy involved in science; (b) using questions that elicited higher order thinking and; (c) providing scaffolds (e.g., purposeful feedback, probing student background knowledge) when confronting abstract scientific concepts. Implications for preservice teacher education are addressed. 相似文献

Teachers’ curricular role identities are those dimensions of their professional identities concerned with the use of curriculum materials. In a previous study,
we developed and tested a survey instrument designed to measure preservice elementary teachers’ development of curricular
role identity for science teaching through their use of science curriculum materials. In this follow-up study, a revised version
of the survey was administered to a second group of preservice elementary teachers in the same science methods course, and
data were analyzed within and across years. Results from this study suggest that preservice teachers articulated important
similarities and differences between the curricular role identities for science teaching they attributed to themselves and
to more experienced elementary teachers. Over time, they were often able to begin to appropriate the curricular role identities
for science teaching that they attributed to more experienced elementary teachers. However, findings from the second survey
administration also suggest that preservice teachers’ curricular role identities for science teaching are more stable when
characterized by their actual curriculum design practices than when characterized by comparative, probabilistic means. These
findings have important implications for science teacher education and curriculum development, as well as the operationalization
of curricular role identity in education research. 相似文献

Sources of Self-efficacy in a Science Methods Course for Primary Teacher Education Students 总被引:1,自引:0,他引:1
D. H. Palmer 《Research in Science Education》2006,36(4):337-353
Self-efficacy has been shown to be an issue of concern for primary teacher education students – many of them have low self-efficacy and this can negatively affect their future teaching of science. Previous research has identified four factors that may contribute towards self-efficacy: enactive mastery experiences, vicarious experiences, verbal persuasion and physiological/affective states. It could also be argued that there are additional sources of self-efficacy that apply to primary teacher education students, namely cognitive content mastery, cognitive pedagogical mastery and simulated modelling. The main purpose of the present paper was to investigate the relative importance of the various sources of self-efficacy in a primary science methods course. Data on changes in self-efficacy and sources of self-efficacy were collected throughout the course using formal and informal surveys. It was found that the main source of self-efficacy was cognitive pedagogical mastery. 相似文献

This study examines the self-efficacy of one preservice elementary school teacher (Kasey) during and after her participation
in Science in Childhood Education—a 16-week, elementary preservice science methods course. The case study of this teacher
is situated in the context of the class as a whole. This is accomplished through interviewing the one teacher and examining
artifacts and observations of the entire class. The results of these experiences are studied to determine what changes have
taken place in the participants’ self-efficacy in science teaching as well as the one preservice teacher in greater detail.
Because self efficacy is influential to student learning, the results of this study have significant implications for the
design of elementary teacher education programs and the support of elementary teachers in teaching science. 相似文献

In this paper we report on teachers’ and students’ participation in authentic science research in out of school time science
clubs at elementary schools. In the program four to five teachers worked alongside practicing scientists as part of their
research groups. Each teacher facilitated a club with 10–15 students who, by extension, were members of the scientists’ research
groups. Over the 3 years of the project nearly 30 teachers and over 500 children participated in the clubs. In this paper
we present a case study of teachers and children who worked with an analytic chemist at a major university whose field of
research is environmental arsenic. We illustrate how the professor mentored the teachers and how they in turn mentored the
children. We show how the elementary school teachers who had very little formal science education gained the expertise needed
to mentor the children. We found that in less than one academic year the teachers were able to gain the knowledge and skills
to facilitate the children’s legitimate participation in authentic scientific research; and that the children gained the methodological
and intellectual proficiency needed to contribute useful data and findings to the scientist’s research program. 相似文献

This study explored the effects that the incorporation of nature of science (NoS) activities in the primary science classroom
had on children’s perceptions and understanding of science. We compared children’s ideas in four classes by inviting them
to talk, draw and write about what science meant to them: two of the classes were taught by ‘NoS’ teachers who had completed
an elective nature of science (NoS) course in the final year of their Bachelor of Education (B.Ed) degree. The ‘non-NoS’ teachers
who did not attend this course taught the other two classes. All four teachers had graduated from the same initial teacher
education institution with similar teaching grades and all had carried out the same science methods course during their B.Ed
programme. We found that children taught by the teachers who had been NoS-trained developed more elaborate notions of nature
of science, as might be expected. More importantly, their reflections on science and their science lessons evidenced a more
in-depth and sophisticated articulation of the scientific process in terms of scientists “trying their best” and “sometimes
getting it wrong” as well as “getting different answers”. Unlike children from non-NoS classes, those who had engaged in and
reflected on NoS activities talked about their own science lessons in the sense of ‘doing science’. These children also expressed
more positive attitudes about their science lessons than those from non-NoS classes. We therefore suggest that there is added value in including NoS activities in the primary science curriculum in that they seem to help children make sense of science and
the scientific process, which could lead to improved attitudes towards school science. We argue that as opposed to considering
the relevance of school science only in terms of children’s experience, relevance should include relevance to the world of
science, and NoS activities can help children to link school science to science itself. 相似文献

The nature of science (NOS) has a prominent role among the national science education content standards at all grade levels, K–12. Results from a national survey of collegiate science educators indicate the perception that the greatest contributors to preservice teachers’ understanding of the nature of science were science methods courses, research projects, and science content courses. Implications of findings are discussed, including connections to current research concerning teacher preparation for effective NOS classroom teaching and student learning.The Nature of Science course on the authors’ campus was initiated in the early 1990s, has evolved, and remains in the required core curriculum for preservice chemistry, earth science, and physics teacher candidates. It is the capstone for NOS insights. It adds to and refines impressions garnered implicitly from science content courses, the methods course, and, for some, an undergraduate research experience. 相似文献

Developing scientifically literate students who understand the socially contextualized nature of science and technology is
a national focus of science education reform. Science educators’ perceptions of risks and benefits of new technologies (such
as biotechnology) may shape their instructional approaches. This study examined the perceived risk of biotechnology of four
groups of science educators: pre-service science teachers, in-service science teachers, biology graduate teaching assistants,
and biology professors (n = 91). Data sources included a survey instrument and card sort task designed to determine the respondents’ structure of risk
perception and factors contributing to this structure. The perceptions of the four educator groups were compared and contrasted
along these dimensions. Results showed that the teacher groups were similar along many aspects of risk perception, but university
professors were more likely to view the more subtle “gray areas” between biotechnology risks. The results are discussed in
the context of understanding teacher risk perception on science pedagogical practice as well as the role of content knowledge
and teaching experience on risk perception formation. 相似文献

Results of various studies suggest that multimedia ‘case methods’ (activities associated with case documentaries) have many
benefits in university-based teacher education contexts. They can, for example, help to ‘bridge the gap’ between perspectives
and practices held by academic teacher educators and those held by student-teachers – who may adhere to perspectives and practices
commonly supported in schools. On the other hand, some studies, along with theoretical arguments, suggest that there are limits
to the effectiveness of multimedia case methods – because, for example, they can never fully represent realities of teaching
and learning in schools. Furthermore, often missing from multimedia case methods is the student-teacher in the role of teacher. To address these concerns, we modified an existing multimedia case method by associating it with a special practice teaching
situation in a school context. Qualitative data analyzed using constant comparative methods suggest that student-teachers
engaged in this modified multimedia case method developed relatively deep commitments to encouraging students to conduct technology
design projects – a non-traditional practice in school science. Factors that appeared to influence development of this motivation
included student-teachers’ pre-instructional perspectives about science and the personalization and contextualization inherent
to the modified multimedia case method.

In this study, pre-service teachers facilitated stations at a family science night as a context to learn to identify, assess,
and use children’s science ideas. Assessment is already difficult in K-12 classrooms. Assessing learning in informal learning
environments adds the complication that participation is largely voluntary. As such, controlling the learners’ participation
to systematically assess learning is counter to the intents of informal environments. The pre-service teachers in this study
experienced success at teaching science and developed understandings about children’s science ideas. Data included reflective
postings, class discussions, observations, artifacts, and photographs. The findings contribute to understanding the value
of multiple learning contexts in teacher preparation and lead to implications about leveraging informal science contexts for
educating teachers. 相似文献

The study explored the influence of university-based teacher education courses on pre-service middle and high school teachers’
experiences with multicultural themes in a secondary science alternative certification program. Eight participants (N = 8), six women and two men, volunteered to be a part of the study that took place over a period of four semesters. Qualitative
data was collected, coded and analyzed to make meaning of the participants’ experiences. Data comprised of participants’ reflective
journals, personal and group interviews, and classroom observations done in middle school practicum and high school student
teaching placements. The findings indicated that while the participants became more familiar with the themes of multicultural
education, many did not demonstrate fluency with these themes and struggled with balancing their responsibilities as a science
teacher and a culturally competent teacher. 相似文献

This longitudinal case study describes the factors that affect an experienced teacher’s attempt to shift her pedagogical practices
in order to implement embedded elements of argument into her science classroom. Research data was accumulated over 2 years
through video recordings of science classes. The Reformed Teacher Observation Protocol (RTOP) is an instrument designed to
quantify changes in classroom environments as related to reform as defined by the National Research Council (National science education standards. Washington, DC: National Academy Press, 1996b) and the National Research Council (Fulfilling the promise: Biology education in the nation’s schools, Washington, DC: National Academy Press, 1990) and was used to analyze videotaped science lessons. Analysis of the data shows
that there was a significant shift in the areas of teacher questioning, and student voice. Several levels of subsequent analysis
were completed related to teacher questioning and student voice. The data suggests a relationship between these areas and
the implementation of scientific argument. Results indicate that the teacher moved from a traditional, teacher-centered, didactic
teaching style to instructional practices that allowed the focus and direction of the lesson to be affected by student voice.
This was accomplished by a change in teacher questioning that included a shift from factual recall to more divergent questioning
patterns allowing for increased student voice. As student voice increased, students began to investigate ideas, make statements
or claims and to support these claims with strong evidence. Finally, students were observed refuting claims in the form of
rebuttals. This study informs professional development related to experienced teachers in that it highlights pedagogical issues
involved in implementing embedded elements of argument in the elementary classroom. 相似文献
