This study explored Saudi elementary school science teachers’ beliefs about the process of teaching and learning science. This involved the exploration of their views about the new Saudi science curriculum, which emphasizes critical thinking and problem solving. Comprehensive interviews were held in 8 schools with 4 male and 6 female—2 of whom were from private schools—science teachers. The interviews were analyzed to identify and assess common themes among their beliefs as well as associations between their beliefs and self-reported classroom practices. The findings revealed perceptual differences between teaching the old and the new science curricula and also that these science teachers were challenged by available class time, the student–teacher ratio, and the lack of laboratory space, equipment, and administrative support. It appears that the more interactive and group-oriented activities that formed the instructional foundation of the new curriculum have increased enjoyment for teaching science and led students to better comprehension of scientific concepts. 相似文献

Abstract Examining how teachers structure the activities in a unit and how they facilitate classroom discussion is important to understand how innovative technology-rich curricula work in the context of classroom instruction. This study compared 2 enactments of an inquiry curriculum, then examined students' learning outcomes in classes taught by 2 teachers. The quantitative data show that there were significant differences in the learning outcomes of students in classes of the 2 teachers. This study then examined classroom enactments by the 2 teachers to understand the differences in the learning outcomes. This research specifically focused on how teacher-led discussions (a) helped connect the activities within a curriculum unit and (b) enabled deeper conceptual understanding by helping students make connections between science concepts and principles. This study examined the role that teacher facilitation played in helping students focus on the relations between the various activities in the unit and the concepts that they were learning. The results point to important differences in the 2 enactments, helping to understand better what strategies might enable a deeper conceptual understanding of the science content. 相似文献

This study explored the effects of community-based service-learning (CBSL), supplemented with discussions and activities about
diversity, on the self-efficacy beliefs of preservice elementary teachers regarding equitable science teaching and learning
for diverse student groups. The study was conducted with 81 preservice teachers enrolled in four sections of an elementary
science methods course over a semester. Employing a mixed-methods research design, data were collected using pretests–posttests
with the study sample and semistructured interviews with a subsample. The results support the value of preservice teachers
engaging in CBSL experiences, supplemented with discussions and activities about diversity, as a way to improve their self-efficacy
beliefs regarding equitable science teaching and learning of all students. 相似文献

Action learning is based on three educational principles—reflection, community, and action—that interrelate and reinforce each other to support ongoing learning about experiences in the workplace. This study explains how an action learning program established for a small group of science teachers in a secondary high school lasted for two years. In this study feedback in the form of student interviews about teaching and learning were introduced to the teacher discussions to enhance the process of action learning. The student feedback gave the teachers an alternative perspective on their experiences and were a catalyst for reflection that helped the teachers to sustain their learning over a period of two years. 相似文献

Situating science concepts in concrete and authentic contexts, using information and communications technologies, including multimodal modeling tools, is important for promoting the development of higher-order thinking skills in learners. However, teachers often struggle to integrate emergent multimodal models into a technology-rich informal learning environment. Our design-based research co-designs and develops engaging, immersive, and interactive informal learning activities called “Embodied Modeling-Mediated Activities” (EMMA) to support not only Singaporean learners’ deep learning of astronomy but also the capacity of teachers. As part of the research on EMMA, this case study describes two prospective teachers’ co-design processes involving multimodal models for teaching and learning the concept of the seasons in a technology-rich informal learning setting. Our study uncovers four prominent themes emerging from our data concerning the contextualized nature of learning and teaching involving multimodal models in informal learning contexts: (1) promoting communication and emerging questions, (2) offering affordances through limitations, (3) explaining one concept involving multiple concepts, and (4) integrating teaching and learning experiences. This study has an implication for the development of a pedagogical framework for teaching and learning in technology-enhanced learning environments—that is empowering teachers to become active sense-makers using multimodal models.

This research examines factors influencing elementary science teacher learning as they participate in professional development with and enactment of educative curricula in comparison with learning following limited professional development and enactment of traditional curricula. Using a randomized cluster design (125 teachers and 2,694 students in 4th—5th grades) that met the What Works Clearinghouse standards without reservations, teacher learning was conceptualized using four outcomes. Data were analyzed using standard single-level multiple regression models and possible mediation models for the teacher outcomes were considered using piecewise multiple regression and path analytic approaches. Treatment group teachers experienced greater increases in content knowledge, views of science inquiry, beliefs about reform-based teaching, and teaching self-efficacy than comparison group teachers. The findings indicate that what teachers learn from the combination of professional development and teaching with educative curriculum varies according to what their knowledge and beliefs are on entering the experience. Surprisingly, high entry-level self-efficacy was associated not only with lower learning gains for the teachers, but also for their students. Finally, teachers' space science learning and that of their students are implicated as mediators of the positive effect of the professional development and educative curriculum enactment on teacher beliefs about reform science teaching. This work refines and extends a theoretical framework of teachers' participatory relationship with curricula. 相似文献

This study examines the effectiveness of a new constructivist curriculum model (Powerful Ideas in Physical Science) in improving prospective teachers’ understanding of science concepts, in fostering a learning environment supporting conceptual understanding, and in promoting positive attitudes toward learning and teaching science and chemistry in particular. A non‐equivalent pretest–post‐test control‐group design was employed. Analysis of covariance and repeated‐measures analyses of variance were performed to analyze the scores on concept tests and attitude surveys. Data from videotaped observations of laboratory sessions and interviews of prospective teachers were analyzed by employing a naturalistic inquiry method to provide insights into the process of science learning and teaching for the teacher trainees. The interpretations were made based on the findings that could be corroborated by both methodologies. Conclusions and limitations of the present study as well as recommendations for future implementation of constructivist science curriculum in general are also included. 相似文献

Teaching in urban schools, with their problems of violence, lack of resources, and inadequate funding, is difficult. It is even more difficult to learn to teach in urban schools. Yet learning in those locations where one will subsequently be working has been shown to be the best preparation for teaching. In this article we propose coteaching as a viable model for teacher preparation and the professional development of urban science teachers. Coteaching—working at the elbow of someone else—allows new teachers to experience appropriate and timely action by providing them with shared experiences that become the topic of their professional conversations with other coteachers (including peers, the cooperating teacher, university supervisors, and high school students). This article also includes an ethnography describing the experiences of a new teacher who had been assigned to an urban high school as field experience, during which she enacted a curriculum that was culturally relevant to her African American students, acknowledged their minority status with respect to science, and enabled them to pursue the school district standards. Even though coteaching enables learning to teach and curricula reform, we raise doubts about whether our approaches to teacher education and enacting science curricula are hegemonic and oppressive to the students we seek to emancipate through education. © 2001 John Wiley & Sons, Inc.

教师的作用:实现文化科学的有效转换 总被引：10，自引：0，他引：10
学习过程是一个“渐进或振荡—高原期—突变”的自组织过程。在教学过程中,教师的“不可替代性”表现在能对学生的文化科学学习起到缩短和加速“渐进或振荡期”和“高原期”的作用。要实现教师的上述作用,教师必须有效地、创造性地把文化科学“转换”为学科或课程,并进一步把学科或课程“转换”为有助于学生全面发展的课堂内外的文化科学学习活动。专业化的教师应该知道学生学习该学科时兴奋点、分歧点、“高原期”何在,能够激活兴奋点、加快逼近分歧点的速度、缩短“高原期”以及维持和推动学生该学科的学习活动。因此,教师要进行学科思想方法和学科发展史实的研究,从课程层面理解教育教学活动,养成教育、教学实践研究的习惯。 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

One of the central challenges globalization and immigration present to education is how to construct school language policies,
procedures, and curricula to support academic success of immigrant youth. This case-study compares and contrasts language
experience narratives along Elena’s developmental trajectory of becoming an urban science teacher. Elena reflects upon her
early language experiences and her more recent experiences as a preservice science teacher in elementary dual language classrooms.
The findings from Elena’s early schooling experiences provide an analysis of the linkages between Elena’s developing English
proficiency, her Spanish proficiency, and her autobiographical reasoning. Elena’s experiences as a preservice teacher in two
elementary dual language classrooms indicates ways in which those experiences helped to reframe her views about the intersections
between language learning and science learning. I propose the language experience narrative, as a subset of the life story,
as a way to understand how preservice teachers reconstruct past language experiences, connect to the present, and anticipate
future language practices. 相似文献

Summary Science teachers naturally rely on their university science experiences as a foundation for teaching middle school science.
This foundation consists of knowledge far too complex for the middle level students to comprehend. In order for middle school
science teachers to utilize their university science training they must search for ways to adapt their college experiences
into appropriate middle school learning experience.
The criteria set forth above provide broad-based guidelines for translating university science laboratory experiences into
middle school activities. These guidelines are used by preservice teachers in our project as they identify, test, and organize
a resource file of hands-on inquiry activities for use in their first year classrooms. It is anticipated that this file will
provide a basis for future curriculum development as the teacher becomes more comfortable and more experienced in teaching
hands-on science.
The presentation of these guidelines is not meant to preclude any other criteria or considerations which a teacher or science
department deems important. This is merely one example of how teachers may proceed to utilize their advanced science training
as a basis for teaching middle school science. 相似文献

The potential of a theory of variation-framed learning study, a teacher professional development approach, to help teachers overcome curricular and pedagogical challenges associated with teaching new science curricula content was explored. With a group of Singapore teachers collaboratively planning and teaching new genetics content, phenomenographic analysis of data corpus from classroom observations, teacher meetings and interviews revealed teacher learning that manifested in the teachers’ experiences. These were captured as (1) increased degrees of student-centered pedagogy and challenges to teachers’ prior assumptions about science pedagogy, (2) increased awareness of possibilities and limitations of their beliefs about science pedagogy, and (3) emergence of new understandings about new curricular content and science pedagogy. The possibility of transformative and generative learning is also discussed. 相似文献

In many countries around the world, there has been an increasing emphasis on improving science education. Recent reform efforts in the USA call for teachers to integrate scientific and engineering practices into science teaching; for example, science teachers are asked to provide learning experiences for students that apply crosscutting concepts (e.g., patterns, scale) and increase understanding of disciplinary core ideas (e.g., physical science, earth science). Engineering practices and engineering design are essential elements of this new vision of science teaching and learning. This paper presents a research study that evaluates the effects of an engineering design-based science curriculum on student learning and attitudes. Three middle school life science teachers and 275 seventh grade students participated in the study. Content assessments and attitude surveys were administered before and after the implementation of the curriculum unit. Statewide mathematics test proficiency scores were included in the data analysis as well. Results provide evidence of the positive effects of implementing the engineering design-based science unit on student attitudes and learning. 相似文献

Research has indicated that most science classrooms are not intellectually demanding and place little emphasis on small group discussions and laboratory activities. However, successful science programs and competent science teaching that can provide models for other science teachers do exist. This study sought to document the teaching practices of two exemplary biology teachers of grades 11 and 12 by means of an interpretive research methodology. Both teachers had a thorough and comprehensive knowledge of the content they were to teach and had a range of teaching strategies that could be used without a great deal of thought. Their expectations for student performance were high, consistent, and firm. Students were expected to complete a high level of academic work in discussions, in problem work, and in laboratory activities, and were encouraged to take responsibility for their own learning. A distinctive feature of these biology classes was the high level of managerial efficiency, where lessons were busy occasions for both teacher and students; students had little opportunity for off-task behavior. Both teachers actively monitored the behavior of both high- and low-ability students by moving around the room and speaking with individuals, while still maintaining control of the entire class. By manipulating questioning and the social environment, both teachers encouraged students to engage in work, gave effective praise to the whole class and to individuals, encouraged student input by referring to it, helped students to effectively use their time, and gave marks for completion of set work. Compared to research with less-successful teachers, these teaching behaviors contributed to exemplary practice. 相似文献

We explored the use of the learning study (LS) model in developing Swedish pre-school science learning. This was done by analysing a 3-cycle LS project implemented to help a group of pre-school teachers (n?=?5) understand their science educational practice, by collaboratively and systematically challenging it. Data consisted of video recordings of 1 screening (n?=?7), 1 initial planning meeting, 3 analysis meetings, 3 interventions, and 78 individual test interviews with the children (n?=?26). The study demonstrated that the teachers were initially uncomfortable with using scientific concepts and with maintaining the children's focus on the object of learning without framing it with play. During the project, we noted a shift in focus towards the object of learning and how to get the children to discern it. As teachers’ awareness changed, enhanced learning was noted among the children. The study suggests that the LS model can promote pre-school science learning as follows: by building on, re-evaluating, and expanding children's experiences; and by helping the teachers focus on and contrast critical aspects of an object of learning, and to reflect on the use of play, imagination, and concepts and on directing the children's focus when doing so. Our research showed that the LS model holds promise to advance pre-school science learning by offering a theoretical tool useable to shift the focus from doing to learning while teaching science using learning activities. 相似文献
