In this study, 12 pre-service mathematics teachers worked in teams to develop their knowledge and skills in using teacher-led spreadsheet demonstrations to help students explore mathematics concepts, stimulate discussions and perform authentic tasks through activity-based lessons. Pre-service teachers’ lesson plans, their instruction of the lessons designed, experiences and lesson enactment outcomes were examined. The pre-service teachers in the study were able to develop and demonstrate their knowledge and skill adequately in designing and enacting activity-based mathematical lessons supported with spreadsheets. The results also showed that the pre-service teachers’ use of the spreadsheet as an instructional tool promoted student in-depth mathematical concept formation and an activity-based learning approach to make lessons less teacher centred and more interactive. 相似文献

The authors describe a journey of self-study during which one author shifted from traditional, teacher-driven approaches to a more problem-based inquiry approach to teaching mathematics. He videotaped a series of lessons taught to sixth-grade students over a semester and analyzed his teaching during discussions with his mentor at the university. The shared analysis helped him learn to involve his students more directly in their own learning. A major lesson learned was that understanding the potential value of a problem-solving approach to teaching mathematics does not guarantee corresponding changes in the classroom. Two vital elements of lesson development emerged as focal points for self-study. After first learning how to prepare worthwhile mathematical tasks, the teacher also learned the importance of implementing effective questioning strategies to help students think more deeply about the mathematics they were learning. 相似文献

This paper discusses the ways in which teacher educators can effectively engage prospective teachers (PTs) in lesson study during mathematics methods courses. Evidence from this work suggests that engagement in lesson study provides PTs with opportunities to strengthen their knowledge about mathematics, students, and pedagogy. More specifically, the results demonstrated that lesson study helped PTs to engage in deep and thoughtful discussions about mathematics, reflect on their teaching, and make effective changes to their lessons that showed noticeable improvements in student learning. Recommendations from this work provide specific methods-course suggestions on the implementation of lesson study as a model for PTs' professional and practitioner development, including strategies and guiding questions that teacher educators can utilize to help deepen PTs' knowledge about mathematics, teaching, and student learning. 相似文献

The analysis identified discursive strategies used by general education teachers in inclusion classrooms to orchestrate and scaffold the verbal participation of all students, including students with learning disabilities (LD). The context was writing instruction. A whole‐class lesson involving teacher–student collaboration to write a text was analyzed for each of two teachers in two urban elementary inclusion classrooms totaling 67 students; 23 students had LD. Analysis of teacher talk focused on procedural strategies (help the lesson run smoothly and make it easier to follow) and involvement strategies (elicit students' attention to and participation in the lesson). Results indicated that both teachers used a variety of similar strategies to provide spaces for student contributions and, at the same time, move the lessons along. However, they also used contrasting strategies unique to their contrasting pedagogical frames of reference (structural vs. interactional). 相似文献

This study explored a modified version of Japanese Lesson Study to determine whether and how it influenced preservice elementary teachers in their abilities to deliver science lessons that included nature of science (NOS) to their own students. We used a case study approach that focused on one subset of a cohort of preservice elementary teachers within their field placement settings. Data sources included lesson plans, lesson feedback forms, videotapes of delivered lessons, and videotapes of lesson study feedback sessions. Early in the semester peers provided feedback on content, and later in the semester peers provided feedback on classroom management as well as content during the lesson study feedback sessions. We found that preservice elementary teachers were able to provide feedback to their peers regarding how to include NOS in their science lessons, yet did not naturally included NOS connections within their own lessons. 相似文献

Twelve lower secondary schoolteachers in mathematics and science were asked to teach a topic of their choice during a lesson that was video-recorded. We were able to analyse 10 of the cases and we found that all of them were similar in one respect: concepts and principles were introduced one at a time, each one followed by examples of the concept or principle in question, apparently to highlight its essential meaning. All the teachers participated in three modified lesson studies with three cycles in four different groups during three semesters. The modified lesson studies were built on a theoretical idea supported by a large number of recent studies. The theory states that new meanings (of concepts and principles, for instance) are learned through engaging with instances of contrasting concepts and principles. The core idea is that new meanings derive from differences, not from sameness. After the three modified lesson studies, the teachers were asked to once again teach the same topic as in the recorded lessons before the lesson studies. The new lessons were also recorded and the analysis showed that there was one thing in common in all cases: all of the 10 teachers dealt with the relevant concepts and principles in relation to each other (i.e. simultaneously) and not one at a time. By thus bringing out the differences between them, their meaning was made possible to grasp for the students. The study lends support to the conjecture that the modified lesson study is a powerful tool for enabling teachers to structure the content of their teaching in accordance with a principle that is more powerful in making learning possible, even if this contradicts their taken-for-granted practice. 相似文献

Abstract Quotations yield the greatest insight from the fewest words. In addition to the wisdom and guidance quotations provide, teachers effectively use quotations in displays, presentations, speeches, research, writing prompts, classroom lessons, and discussions. Students employ quotations for speeches, classroom assignments, as sources of inspiration and guidance, and as support for essays—particularly those required for entrance to college. Considering the fast-paced, media culture in which today’s students thrive, adolescents in a hurry embrace a quotation ranging from five to six words to three or four sentences. As a change of pace from textbook passages, short stories, poems, and novels, teachers find it refreshing to use quotations to stimulate thought and focus on the development of communication, thinking, and social skills. Although the lesson strategies outlined in this article use sample quotations most appropriately used in English classes, other subject area teachers, librarians, counselors, and administrators will also find value in many of the strategies. 相似文献

Abstract This article reports on a project which involved enabling teachers in Hong Kong primary schools to use an online integrated learning environment (ILE) to design lesson plans to cater for students with different learning abilities. Teachers explored ways of using technology to enhance student learning. A case-study approach was used to collect data on individual teacher developments and document evolving classroom teaching strategies. The findings revealed that when using the ILE teachers were able to: 1. effectively design and create lessons which catered for different ability groups within the class; 2. employ varied teaching strategies to cater for different learning needs of students in the class; 3. shift from more traditional pedagogical approaches to embracing learner-centred principles which achieve a higher degree of classroom interaction; and 4. collaborate with others, discuss their feelings more honestly, evaluate and reflect on their own practice. 相似文献

This study combines the Japanese lesson study approach and mathematics teachers’ professional development. The first year of a 4-year project in which 3 Dutch secondary school teachers worked cooperatively on introducing making sense of the calculus is reported. The analysis focusses on instrumental and relational student understanding of mathematical concepts and the transition between the conceptual embodiment and the operational symbolism of the calculus. This paper reports on 2 cycles of lesson studies that took place in the first project year, the first cycle focussing on the notion of the derivative (introduced for polynomials) and the second on trigonometry (as the concepts shift from ratios in a right-angled triangle to functions in the calculus). The lesson study cycles resulted in changes in the teachers’ educational goals and instructional strategies in relation to student understanding. However, the teachers’ desire to be good teachers, their perceived need to prepare students for standard examinations and their reluctance to use computers impeded their progress in developing a lesson study approach. The introduction of a Japanese lesson study approach into a Dutch context merits further reflection in the later years of the project. 相似文献

The conservation of biodiversity is an important socio‐scientific issue that is often regarded as a precondition to sustainable development. The foundation for citizens’ understanding of conservation issues can be laid down in formal school education. This research focuses on decision‐making discussions about biological conservation issues among 131 15–16‐year‐old students, to address two main research questions:
-
Can peer group decision‐making discussions, in a normal science lesson setting, help develop students’ personal reasoning in relation to conservation issues?
-
Are there features common to high quality discussions about conservation which might be readily identified by classroom teachers?

This study sought to identify specific types of discussion-based strategies that two successful high school physics teachers using a model-based approach utilized in attempting to foster students' construction of explanatory models for scientific concepts. We found evidence that, in addition to previously documented dialogical strategies that teachers utilize to engage students in effectively communicating their scientific ideas in class, there is a second level of more cognitively focused model-construction-supporting strategies that these teachers utilized in attempting to foster students' learning. A further distinction between macro and micro strategy levels within the set of cognitive strategies is proposed. The relationships between the resulting three levels of strategies are portrayed in a diagramming system that tracks discussions over time. The study attempts to contribute to a clearer understanding of how discussion-leading strategies may be used to scaffold the development of conceptual understanding. 相似文献

A video-based program on lesson analysis for pre-service mathematics teachers was implemented for two consecutive years as part of a teacher education program at the University of Lazio, Italy. Two questions were addressed: What can preservice teachers learn from the analysis of videotaped lessons? How can preservice teachers’ analysis ability, and its improvement, be measured? Two groups of preservice teachers (approximately 140 in total) participated in the program. A three-step lesson analysis framework was applied to three lesson videos: (1) goal(s) and parts of the lesson; (2) student learning; and, (3) teaching alternatives. Preservice teachers’ ability to analyze lessons was measured through an open-ended pre- and post-assessment. In the assessment, preservice teachers were asked to mark and comment on events (in a lesson not included in the program) that they found interesting for: teachers’ actions/decisions; students’ behavior/learning; and, mathematical content. A coding system was developed based on five criteria: elaboration, mathematics content, student learning, critical approach, and alternative strategies. In both studies, the ability to analyze instruction improved significantly on all five criteria. These data suggest promising directions for the development of both an instrument to measure lesson analysis abilities and a model for teacher learning. 相似文献

We report here on the first of two evaluations of a national project (Getting Practical: Improving Practical Work in Science—IPWiS) designed to improve the effectiveness of practical work in both primary and secondary schools in England. This first baseline evaluation of the effectiveness of practical work is based on a study of a diverse range of 30 practical lessons undertaken in non‐selective primary (n = 10) and secondary (n = 20) schools prior to the teachers undertaking a training intervention designed to improve their effective use of practical work. A multi‐site case study approach employing a condensed fieldwork strategy was used in which data were collected, using audiotape‐recorded discussions, interviews, and observational field notes. The analysis, based on work by Millar et al. and Tiberghien, considers what students do and think relative to what their teacher intended them to do and think. In both primary and secondary schools, the widespread use of highly structured “recipe” style tasks meant that practical work was highly effective in enabling students (n = 857) to do what the teacher intended. Whilst tasks in primary schools tended to be shorter than in secondary schools, with more time devoted to helping students understand the meaning of new scientific words, neither primary nor secondary teachers' lesson plans incorporated explicit strategies to assist students in making links between their observations and scientific ideas. As such, tasks were less effective in enabling students to use the intended scientific ideas to understand their actions and reflect upon the data they collected. These findings suggest that practical work might be made more effective, in terms of developing students' conceptual understanding—an aim of the IPWiS project—if teachers adopted a more “hands‐on” and “minds‐on” approach and explicitly planned how students were to link these two essential components of practical work. © 2012 Wiley Periodicals, Inc.

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

Lesson study is highly regarded as a model for professional learning, yet remains under-theorised. This article examines the professional learning experiences of teachers and numeracy coaches from three schools in a local network of schools, participating in a lesson study project over two research cycles in 2012. It maps the interconnections between their experiences and their beliefs and practices, using Clarke and Hollingsworth’s (Teach Educ 18(8):947–967, 2002) Interconnected Model of Professional Growth. Analysis of interview data and video-recordings of planning meetings, research lessons, and post-lesson discussions reveals the development of teachers’ collaborative planning skills, increased attention to students’ mathematical thinking, use of orchestrated whole-class discussion based on anticipated student solutions and focused questioning, and the enhancement of collaborative practices for teacher inquiry. Our findings illuminate the interplay between the External Domain, the Personal Domain, the Domain of Practice, and the Domain of Consequence, in the teaching and learning change environment, and the mediating processes of enactment and reflection. Changes in the domains across the period of the lesson study provide evidence of teachers’ professional growth, with the iterative processes of enactment and reflection being critical in mediating this professional growth. 相似文献

This paper describes a method of analysing teacher growth in the context of science education. It focuses on the identification of pathways in the development of secondary school teachers’ pedagogical content knowledge (PCK) by the use of the interconnected model of teachers’ professional growth (IMTPG).The teachers (n = 12) participated in a one-year action research project focused on their individual concerns related to teaching science. The use of the IMTPG revealed that teachers use different pathways of learning to develop different aspects of their PCK. For each PCK component, three distinct pathways could be identified, two of which clearly were associated with professional growth. When examining these two pathways in detail, it was found that (1) teachers learned about new instructional strategies and assessment methods mostly through literature reviews and discussions with peers and (2) teachers who analyzed and reflected on student learning as it happened in their classrooms developed understandings that helped them to select and apply instructional strategies to further promote student learning. Both the analytical method as well as the identification of the different developmental pathways help to better understand teacher development in the context of classroom practices. 相似文献
