This study investigated the impact of teacher design teams as a professional development arrangement for developing technology integration knowledge and skills among in-service science teachers. The study was conducted at a secondary school in Tanzania, where 12 in-service science teachers participated in a workshop about technology integration in science teaching and worked in design teams to prepare technology-enhanced biology, chemistry and physics lessons. Through collaboration in design teams, teachers were able to make science animations using PowerPoint and record videos to use in their teaching. The designed lessons were taught in the classroom and reflected upon thereafter by all teachers. In order to determine the change in teachers’ technology integration knowledge and skills, data were collected before and after the professional development arrangement by using questionnaire, interview and observation data. Focus group discussion and reflection questionnaire data were used to assess teachers’ experience of working in design teams at the end of the professional development arrangement. Findings showed an increase in teachers’ technology integration knowledge and skills between pre- and post-measurements. Collaboration in design teams had the potential for teachers to share knowledge, skills, experience and challenges related to technology-enhanced teaching.  相似文献

Advances in online geospatial technologies (GST) have expanded access to K-12 classrooms which has implications for the support teachers require to effectively integrate GSTs to promote learning. Previous studies have shown the impact of GST-integrated lessons on student engagement, spatial thinking skills, and/or content knowledge; however, most of these studies have been small in scope and scale and frequently focus on the affordances of the technology, without addressing the context of the implementation and student characteristics for whom GST is most impactful. We attempt to address some of these gaps. Our program scaled an effective GST-focused professional learning and development program to a national audience through a facilitator development model. This paper explores the student characteristics and lesson factors that resulted in student interest in science and technology and careers in those fields. After teaching a Geospatial Inquiry lesson created during a teacher workshop, teachers (n = 82) submitted the lessons and surveys on the implementation of Geospatial Inquiry lessons. The implementation surveys and lessons were scored for alignment to the principles of high-quality Geospatial Inquiry. Students (n = 1924) completed a post-lesson retrospective survey and indicated the extent to which their perceptions and attitudes toward science and technology changed because of the lesson. Results indicate that teacher GST performance is associated with increases in student outcomes. Students with previous exposure to science activities were more likely to have increased interest and excitement in science and careers in science but decreased interest in technology careers. Students who had previous exposure to technology activities had increased interest and excitement in technology and careers in technology but decreased interest in science careers. Geospatial Inquiry lessons also had a significant impact on students who are traditionally underrepresented in STEM fields. After participating in the lessons, students who identify as female reported higher engagement and interest in science and higher interest in science careers. Students who identified as Black or Hispanic also reported higher interest and excitement in science and technology, and students who identified as Black reported marginally higher interest in science careers.  相似文献

Elementary teachers face increasing demands to engage children in authentic science process and argument while simultaneously preparing them with knowledge of science facts, vocabulary, and concepts. This reform is particularly challenging due to concerns that elementary teachers lack adequate science background to teach science accurately. This study examined 81 in-classroom inquiry science lessons for preservice education majors and their cooperating teachers to determine the accuracy of the science content delivered in elementary classrooms. Our results showed that 74 % of experienced teachers and 50 % of student teachers presented science lessons with greater than 90 % accuracy. Eleven of the 81 lessons (9 preservice, 2 cooperating teachers) failed to deliver accurate science content to the class. Science content accuracy was highly correlated with the use of kit-based resources supported with professional development, a preference for teaching science, and grade level. There was no correlation between the accuracy of science content and some common measures of teacher content knowledge (i.e., number of college science courses, science grades, or scores on a general science content test). Our study concluded that when provided with high quality curricular materials and targeted professional development, elementary teachers learn needed science content and present it accurately to their students.  相似文献

This article draws six key lessons from cognitive science for teachers of critical thinking. The lessons are: acquiring expertise in critical thinking is hard; practice in critical-thinking skills themselves enhances skills; the transfer of skills must be practiced; some theoretical knowledge is required; diagramming arguments (“argument mapping”) promotes skill; and students are prone to belief preservation. The article provides some guidelines for teaching practice in light of these lessons.  相似文献

ABSTRACT

Collaborative design positively affects both professional development and the implementation of curriculum change, because teachers develop competencies and practice and develop ownership of the change. The current study was aimed to explore what empirical evidence is available about processes that take place when teachers co-design and how these contribute to professional development and curriculum change. Evidence from 14 PhD studies was collected to study their impact on teacher learning and curriculum change, by analysing effects, mechanisms, and conditions. Results showed that effects of curriculum design teams, in terms of learning outcomes for teachers in areas such as (pedagogical) content knowledge and design knowledge and skills, became manifest in the outcomes of the curriculum design process, and in the appreciation by the stakeholders. We concluded that professional development, through collaborative design in teams, which is specific and linked to the curriculum, influences teachers’ knowledge and practice and impacts implementation of curriculum change.  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 pilot study investigates the impact of a 2-week professional development Summer Institute on PK-3 teachers’ knowledge and practices. This Summer Institute is a component of [program], a large-scale early-childhood science project that aims to transform PK-3 science teaching. The mixed-methods study examined concept maps, lesson plans, and classroom observations to measure possible changes in PK-3 teachers’ science content knowledge and classroom practice from 11 teachers who attended the 2014 Summer Institute. Analysis of the concept maps demonstrated statistically significant growth in teachers’ science content knowledge. Analysis of teachers’ lesson plans demonstrated that the teachers could design high quality science inquiry lessons aligned to the Next Generation Science Standards following the professional development. Finally, examination of teachers’ pre- and post-Summer Institute videotaped inquiry lessons showed evidence that teachers were incorporating new inquiry practices into their teaching, especially regarding classroom discourse. Our results suggest that an immersive inquiry experience is effective at beginning a shift towards reform-aligned science and engineering instruction but that early elementary educators require additional support for full mastery.  相似文献

This study investigates the process of identifying high-quality lessons for gifted learners that integrate the arts with science, technology, engineering, and mathematics (STEM) fields. These STEAM lessons have the potential to develop deep thinking, as well as develop creativity and visual–spatial skills that are necessary in the STEM disciplines. Lessons were solicited from teachers through their involvement in national organizations, and 61 lessons were analyzed and reviewed by experts in the arts and STEM fields, as well as master teachers. High-quality lessons provided deep content knowledge in both STEM and arts fields, connections across content areas, specific criteria for assessment, and collaborations between teachers and between students. The findings from this study will be used to further define the evaluation process for STEAM lessons designed for gifted learners and to develop professional development opportunities for teachers of the gifted.  相似文献

This article presents a quasi-experimental study comparing the impact of two technology-related teacher professional development (TTPD) designs, aimed at helping junior high school science and mathematics teachers design online activities using the rapidly growing set of online learning resources available on the Internet. The first TTPD design (tech-only) focused exclusively on enhancing technology knowledge and skills for finding, selecting, and designing classroom activities with online resources, while the second (tech?+?pbl) coupled technology knowledge with learning to design problem-based learning (PBL) activities for students. Both designs showed large pre-post gains for teacher participants (N?=?36) in terms of self-reported knowledge, skills, and technology integration. Significant interaction effects show that teachers in the tech?+?pbl group had larger gains for self-reported knowledge and externally rated use of PBL. Three generalized estimating equation (GEE) models were fit to study the impact on students?? (N?=?1,247) self reported gains in behavior, knowledge, and attitudes. In the resulting models, students of tech?+?pbl teachers showed significant increases in gain scores for all three outcomes. By contrast, students of tech-only teachers showed improved gains only in attitudes.  相似文献

Analogies have been argued to be central in the process of establishing conceptual growth, making overt connections and carryover into an intended cognitive domain, and providing a generative venue for developing conceptual understanding inherent in constructivist learning. However, students' specific uses of analogies for constructing arguments are not well understood. Specifically, the results of preservice teachers' knowledge gains are not widely studied. Although we would hope that engaging preservice science teachers in exemplary lessons would assist them in using and generating analogies more expertly, it is not clear whether or how such curricula would affect their learning or teaching. This study presents an existence proof of how preservice science teachers used analogies embedded in their course materials Physics by Inquiry. This fine‐grained analysis of small group discourse revealed three distinct roles of analogies including the development of: (a) cognitive process skills, (b) scientific conceptual understanding, and (c) social contexts for problem solving. Results suggest that preservice teachers tend to overgeneralize the analogies inserted by curriculum materials, map irrelevant features of analogies into collaborative problem solving, and generate personal analogies, which counter scientific concept development. Although the authors agree with the importance of collaborative problem solving and the insertion of analogies for preservice teachers' conceptual development, we believe much more needs to be understood before teachers can be expected to construct and sustain effective learning environments that rely on using analogies expertly. Implications for teacher preparation are also discussed. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 443–463, 2003  相似文献

The new Advanced Placement (AP) Computer Science (CS) Principles course increases the need for quality CS teachers and thus the need for professional development (PD). This article presents the results of a 2-year study investigating how teachers teaching the AP CS Principles course for the first time used online PD material. Our results showed that the teaching and computing background of teachers had a significant impact on the teachers' need for and use of online PD material. More specifically, novice CS teachers needed and used PD for developing their pedagogical content knowledge (PCK). Non-CS teachers needed and used PD materials emphasizing content knowledge. Experienced CS teachers believed they had little need for PD even though they were teaching a new course. Our study makes three recommendations for designing effective online PD for CS teachers: match PD to teachers' background, align PD with the course curriculum, and use effective motivational design to enhance teacher engagement.

This is a narrative inquiry into the role of professional development in the construction of teaching practice by an exemplary urban high school science teacher. I collected data during 3 years of ethnographic participant observation in Marie Gonzalez’s classroom. Marie told stories about her experiences in ten years of professional development focused on inquiry science teaching. I use a social practice theory lens to analyze my own stories as well as Marie’s. I make the case that science teaching is best understood as mediated by socially-constructed identities rather than as the end-product of knowledge and beliefs. The cognitive paradigm for understanding teachers’ professional learning fails to consistently produce transformations of teaching practice. In order to design professional development with science teachers that is generative of new knowledge, and is self-sustaining, we must understand how to build knowledge of how to problematize identities and consciously use social practice theory.  相似文献

This paper presents the development and implementation of a professional development workshop series on integrating mobile phones into science teaching for a group of teachers in Sri Lanka. The series comprised a 3‐day Planning Workshop followed by implementation of the planned lessons in real classrooms and a subsequent 1‐day Reviewing Workshop. During the Planning Workshop, teachers were provided with a hands‐on‐session on the use of mobile phones in science teaching followed by collaborative lesson planning activities. The methodological approach taken to evaluating the initiative was qualitative, and data were collected using observations and fieldnotes. The data were analysed using thematic analysis techniques with the support of NVivo8 (QSR International Pty Ltd., Victoria, Australia) qualitative data analysis software. It was found that as professional development for teachers was provided separately as Planning and Reviewing Workshops, these workshops supported the teachers in recognising the educational potential of mobile phones, in learning how to use them in science teaching and learning, in changing their attitudes towards the use of mobile phones in teaching and in sharing knowledge and skills relating to mobile phone applications in science teaching and learning.  相似文献

The Midwest Expansion of the Child-Parent Center Education Program (MCPC) is a pre-K to 3rd grade intervention program aimed at improving economically disadvantaged children's school success by enhancing continuity in instruction and increasing parental involvement. Opened in Chicago in the 1960s, this school reform model has undergone significant changes and is currently being expanded in five demographically heterogeneous school districts in Illinois and Minnesota. This article describes the collaborative process that has contributed to effective implementation of the expansion project within at-risk communities. Three themes of collaboration are emphasized: (a) improving the quality of data, (b) establishing and maintaining implementation fidelity, and (c) using research to inform practice. We discuss lessons learned from our partnerships with a number of collaborators including those involved with implementing the pre-K program, researching and evaluating the project, and providing professional development to teachers. Consideration is given to advancing the field of implementation science by successfully initiating and enhancing exemplary partnerships in comprehensive school reforms through effective research design.  相似文献

The implementation of effective science programmes in primary schools is of continuing interest and concern for professional developers. As part of the Australian Academy of science's approach to creating an awareness ofPrimary Investigations, a project team trialed a series of satellite television broadcasts of lessons related to two units of the curriculum for Year 3 and 4 children in 48 participating schools. The professional development project entitledSimply Science, included a focused component for the respective classroom teachers, which was also conducted by satellite. This paper reports the involvement of a Year 4 teacher in the project and describes her professional growth. Already an experienced and confident teacher, no quantitative changes in science teaching self efficacy were detected. However, her pedagogical content knowledge and confidence to teach science in the concept areas of matter and energy were enhanced. Changes in the teacher's views about the co-operative learning strategies espoused byPrimary Investigations were also evident. Implications for the design of professional development programmes for primary science teachers are discussed.  相似文献

This paper uses cultural historical activity theory to examine the interactions between the choices primary teachers make in the use of practical activities in their teaching of science and the purposes they attribute to these; their emotions, background and beliefs; and the construction of their identities as teachers of science. It draws on four case studies of science lessons taught over a term by four exemplary teachers of primary science. The data collected includes video recordings of science lessons, interviews with each teacher and some of their students, student work, teachers?? planning documents and observation notes. In this paper, we examine the reflexive relationship between emotion and identity, and the teachers?? objectives for their students?? learning; the purposes (scientific and social) the teachers attributed to practical activities; and the ways in which the teachers incorporated practical activities into their lessons. The findings suggest that it is not enough to address content knowledge, pedagogy and pedagogical content knowledge in teacher education, but that efforts also need to be made to influence prospective primary teachers?? identities as scientific thinkers and their emotional commitment to their students?? learning of science.  相似文献

Professional knowledge is an important source of science teachers' actions in the classroom (e.g., personal professional content knowledge [pedagogical content knowledge, PCK] is the source of enacted PCK in the refined consensus model [RCM] for PCK). However, the evidence for this claim is ambiguous at best. This study applied a cross-lagged panel design to examine the relationship between professional knowledge and actions in one particular instructional situation: explaining physics. Pre- and post a field experience (one semester), 47 preservice physics teachers from four different universities were tested for their content knowledge (CK), PCK, pedagogical knowledge (PK), and action-related skills in explaining physics. The study showed that joint professional knowledge (the weighted sum of CK, PCK, and PK scores) at the beginning of the field experience impacted the development of explaining skills during the field experience (β = .38**). We interpret this as a particular relationship between professional knowledge and science teachers' action-related skills (enacted PCK): professional knowledge is necessary for the development of explaining skills. That is evidence that personal PCK affects enacted PCK. In addition, field experiences are often supposed to bridge the theory-practice gap by transforming professional knowledge into instructional practice. Our results suggest that for field experiences to be effective, preservice teachers should start with profound professional knowledge.  相似文献

The implementation of new content and pedagogical standards in science education in Israel as well as in other countries necessitates intensive, life-long professional development of science teachers. Here we describe a model for the professional development of chemistry teacher-leaders. In the first part of the paper, we describe a model for the development and change of chemistry teacher-leaders. In the second part of the paper, we present the assessment of teachers' change. It is suggested, that in order to become a leader, the teacher has to undergo several interrelated phases of development and changes, namely personal, professional, and social. In order to attain these changes, a two-year program was designed in which teachers were given opportunities to develop their content knowledge, pedagogical content knowledge, and their leadership abilities and skills. The assessment of teachers' professional development clearly showed that engaging teachers in a long-term professional development program changed their beliefs (personal change) regarding their role as chemistry teachers in general and their confidence to become leaders in particular. In addition, we observed that the teachers changed in their professional abilities as well as in their social behavior. We also report on the involvement of the teacher-leaders in activities in which leadership skills were implemented in attempting to reform chemistry education in Israel.  相似文献
