The majority of public school teachers do not feel well prepared to use instructional technology. Professional development on computer-based concept mapping responds to this concern through focusing on a tool/software that has many applications and is not difficult to master. A subset (n = 18) of science teachers in a Health Sciences and Technology Academy (HSTA) completed a workshop on electronic concept mapping and were provided with school site licenses and other follow-up support (summer institute). They utilized the software in academic enrichment for underserved students, regular classroom instruction, and inservice training for colleagues. Triangulation of findings from data sources (electronic conferencing, lesson plans, workshop evaluations) revealed that HSTA teachers embrace electronic concept mapping as a versatile educational tool. Factors contributing to this enthusiasm included the ease with which students use the software, the transparent nature of the learning process for these students, and the positive attitudes of colleagues whom they have inserviced. The findings from this project are congruent with what experts contend to be critical features of effective teacher professional development: facilitating a community of learners and providing sustained support. This project now funds software use in over 45 public schools.  相似文献

In this study, we investigated the value of a concept map marking guide as an alternative formative assessment tool for science teachers to adopt for the topic of energy. Eight high school science teachers marked students’ concept maps using an itemized holistic marking guide. Their marking was compared with the researchers’ marking and the scores of a multiple-choice diagnostic test. Statistical analysis revealed that teachers evaluated students’ concept maps consistently, but the concept map scores were only mildly correlated with the multiple-choice test scores. We explored what each assessment method revealed in terms of students’ understanding with one student’s performance as a showcase. Teachers’ views on using the marking guide of concept maps as an assessment tool were also included. We discuss the value of the concept map marking guide as a formative assessment tool for science teachers to create and modify in order to encourage students’ conceptual learning.  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 is an investigation of the impact of collaborative teaching by student‐teachers and classroom teachers on children’s enjoyment and learning of science. The paper describes findings from a project in which undergraduate science specialist student‐teachers were placed in primary schools where they ‘co‐taught’ investigative science and technology with primary teachers. Almost six months after the student placement, a survey of children’s attitudes to school science revealed that these children enjoyed science lessons more and showed fewer gender or age differences in their attitudes to science than children who had not been involved in the project. The authors discuss how this model of collaborative planning, teaching and evaluation can both enhance teacher education and improve children’s experience of science.  相似文献

The investigators evaluated the SOAR-High (Science, Observing, and Reporting-High School) Project, a web-based earth systems science course involving collaborating teachers and deaf students at high schools in California, Washington, DC, and Indiana. In SOAR-High, students use Internet- and computer-based technologies to gather and report information. The investigators and stakeholders identified 4 key questions: (a) Are the SOAR-High students becoming proficient in using the science process skills? (b) Do the SOAR-High curriculum materials explicitly stress the use of science process skills? (c) Do the SOAR-High students develop skills to work independently? (d) Does the SOAR-High Project aid in student motivation? Quantitative and qualitative evaluative tools to address each question included student and teacher interviews, classroom observations, performance-based tasks, and reviews of student website work. Findings showed convincing evidence for affirmative answers to all 4 questions. However, some students described difficulties with the reading levels of the SOAR-High materials; some teachers expressed concern about SOAR-High's effectiveness because of its use with students at different grade levels.  相似文献

This paper deals with a required methods course, based on the national curriculum of science and technology for junior high schools. The course participants are pre-service teachers who study towards a B.Sc. degree in education in science and technology parallel to their studies in one of the faculties of sciences or engineering. Working in small teams, the students carry out a project in a Project-Based Learning (PBL) environment. The final outcomes of the project are group and individual written reports, a portfolio, a multimedia presentation and a physical model. The research question was: what implementation issues and processes do higher education students encounter in a Project-Based Learning environment which involves an alternative assessment approach? Qualitative and quantitative tools for collecting data included ‘the participant as observer’ observations at the classroom, semi-structured interviews with students, questionnaire, and analysis of students' reports and products. The findings relate to the advantages of PBL from the students' point of view, the challenges students experienced and perceived while conducting their projects, and the benefits students may gain from formative assessment.  相似文献

Research and design activities are often employed in STEM (Science, Technology, Engineering & Mathematics) education. This study aims to examine students’ attitudes towards doing research and design activities in secondary school, among two groups of students: (1) students that take the quite recently introduced Dutch subject O&O (research & design), in which students perform authentic research and design projects related to STEM disciplines; and (2) students that do not take O&O. The subject O&O is only taught at a limited number of certified, so called ‘Technasium’, schools. A questionnaire, developed by the authors, was completed by 1625 students from Grades 8 and 11. Unlike previous studies on student attitudes, which usually use abstract concepts like ‘science’ or ‘technology’, the questionnaire used in this study contains active verbs to characterise research and design activities. The results showed that, in general, students who took the subject O&O had more positive attitudes towards doing research and design activities than regular students. Both student groups appeared to find doing design activities more enjoyable than doing research activities. The results of this study provide useful information for teachers as well as teacher educators about the existing attitudes of students, for example their preference for design projects over research projects.  相似文献

This qualitative investigation explored the beliefs and practices of one secondary science teacher, Diane, who differentiated instruction and studied how technology facilitated her differentiation. Diane was selected based on the results of a previous study, in which data indicated that Diane understood how to design and implement proactively planned, flexible, engaging instructional activities in response to students’ learning needs better than the other study participants. Data for the present study included 3 h of semi-structured interview responses, 37.5 h of observations of science instruction, and other artifacts such as instructional materials. This variety of data allowed for triangulation of the evidence. Data were analyzed using a constant comparative approach. Results indicated that technology played an integral role in Diane’s planning and implementation of differentiated science lessons. The technology-enhanced differentiated lessons employed by Diane typically attended to students’ different learning profiles or interest through modification of process or product. This study provides practical strategies for science teachers beginning to differentiate instruction, and recommendations for science teacher educators and school and district administrators. Future research should explore student outcomes, supports for effective formative assessment, and technology-enhanced readiness differentiation among secondary science teachers.  相似文献

This study explores elementary teachers’ social understandings and employment of directives and politeness while facilitating inquiry science lessons prior and subsequent to their participation in a summer institute in which they were introduced to the scholarly literature on regulative discourse (directives used by teachers to regulate student behavior). A grounded theory analysis of the institute professional development activities revealed that teachers developed an increased awareness of the authoritative functions served by impolite or direct directives (i.e., pragmatic awareness). Furthermore, a comparative microethnographic analysis of participants’ inquiry-based classroom practices revealed that after the institute teachers demonstrated an increased ability to share authority with students by strategically making directive choices that were more polite, indirect, inclusive, involvement-focused and creative. Such ability led to a reduced emphasis on teacher regulation of student compliance with classroom behavioral norms and an increased focus on the discursive organization of the inquiry-based science learning/teaching process. Despite teachers’ increased pragmatic awareness, teacher–student linguistic relationships did not become entirely symmetrical subsequent to their participation in the summer institute (i.e., teacher authority was not completely relinquished or lost). Based on such findings, it is argued that teachers need to develop higher levels of pragmatic awareness to become effectively prepared to engage in language-mediated teacher–student interaction in the context of inquiry-based science classroom discourse.  相似文献

In this study, concept map activities were used to trigger group discussions about inclusive education, with a focus on learners with disabilities. The participants were 226 Tanzanian student teachers. This article reports and discusses how the maps were analysed and what they indicate about the students’ thinking about certain aspects of inclusive education. The results also indicate that concept mapping as an activity in teacher education may be useful and engaging for students. It may help them to organise knowledge and make them aware of their own and others’ understanding of inclusive education practices. An analysis of concept maps constructed by student teachers may also help lecturers to identify views, misconceptions, knowledge gaps and insights about inclusion in education settings.  相似文献

The purpose of this study was to understand how an 8th grade science class used a structured problem-based learning (PBL) strategy to study volcanoes and to discuss some of the issues that science teachers might encounter when designing and implementing the PBL strategy. This study took place at Collins Middle School, which is located in a cosmopolitan community in Illinois. The PBL lessons, which a teacher taught cooperatively with his student-teacher, required ten class periods to study two real-life volcanic phenomena. The guiding research questions were: (a) in what ways did the teachers (Mr. Brown and Ms. Jones) facilitate student learning about volcanoes using the PBL strategy?; and (b) what were the students’ engagements like during the PBL classes on a volcano unit? This study’s findings supported three main assertions: first, the teachers’ questions and group dynamics guided and facilitated the students’ course of learning; second, with the teachers’ specific guidance, the students collaboratively built up their supporting evidence; most of the supporting evidence was much more developed than just listing the terms or simple facts on volcanoes; and, third, there existed a tension between the teachers’ ideals and the implementation of the PBL strategy. They tended to slip into the traditional role of focusing on scientific facts about volcanoes.  相似文献

The intent of national efforts to frame science education standards is to promote students’ development of scientific practices and conceptual understanding for their future role as scientifically literate citizens (NRC 2012). A guiding principle of science education reform is that all students receive equitable opportunities to engage in rigorous science learning. Yet, implementation of science education reform depends on teachers’ instructional decisions. In urban schools serving students primarily from poor, diverse communities, teachers typically face obstacles in providing reform-based science due to limited resources and accountability pressures, as well as a culture of teacher-directed pedagogy, and deficit views of students. The purpose of this qualitative research was to study two white, fourth grade teachers from high-poverty urban schools, who were identified as transforming their science teaching and to investigate how their beliefs, knowledge bases, and resources shaped their planning for reform-based science. Using the Shavelson and Stern’s decision model for teacher planning to analyze evidence gathered from interviews, documents, planning meetings, and lesson observations, the findings indicated their planning for scientific practices was influenced by the type and extent of professional development each received, each teacher’s beliefs about their students and their background, and the mission and learning environment each teacher envisioned for the reform to serve their students. The results provided specific insights into factors that impacted their planning in high-poverty urban schools and indicated considerations for those in similar contexts to promote teachers’ planning for equitable science learning opportunities by all students.  相似文献

Abstract

The article sets the context in which primary science educators find themselves, following the publication in England and Wales of the two recent DfEE circulars (10/97 and 4/98), Teaching: High Status, High Standards. The implications of trainee teachers demonstrating a wide range of standards, both of teaching ability and personal subject knowledge levels, by the end of their courses, are considered. The research was carried out by questioning staff from 32 teacher training institutions, who attended a conference in the early summer of 1998, where the focus was looking at strategies for auditing and enhancing trainee teachers’ subject knowledge. The results indicated that few institutions had foreseen the changes by previously planning for the introduction of subject auditing of trainees, but that all institutions had plans afoot for introducing it both on entry, and during the course. Techniques were based mainly around student self‐assessment, monitored by tutors, using strategies such as evidence portfolios, concept mapping, etc. Strategies such as multiple‐choice testing and computer assessment were envisaged as being used to a lesser extent.  相似文献

University students are too often challenged by their limited skills in application, investigation, relational thinking, and communication of ideas. In this study, we have combined 3 tools that potentially can support and foster students’ development in the above mentioned areas through student collaboration, concept mapping, and electronic technologies. The participants in this study were 26 students in two intact classes in learning theories. In groups of 3 to 5 students, they were asked to generate 3 concept maps and accompanying prose over the term on 3 major issues in the field of learning. Through the use of interviews, questionnaires, and student generated concept maps, students reportedly enjoyed concept mapping for its organizational and relational properties but preferred sharing their concept maps and dialoguing with one another in a synchronous mode where immediate feedback and flow of thinking could be maintained when involved in constructing maps. Moreover, they did not like the redundancy offered by both prose and concept map outputs, suggesting that while concept mapping can be an arena for generating and generally structuring ideas, prose can be a means of communicating such ideas in a form that is common to most people. This is particularly important for teachers and students who have difficulty navigating through maps alone.  相似文献

Abstract

This randomized, controlled field trial estimated the causal impact of a technology-based geometry curriculum on students’ geometry achievement, as well as their attitudes toward mathematics and technology. The curriculum combines learner-centered classroom pedagogy with individualized, computer-based student instruction. Conducted over a 3-year period in eight high schools within an urban fringe district, the study found that students assigned to the treatment curriculum scored 19% of a standard deviation lower on the geometry posttest than their counterparts assigned to the district's standard curriculum, but found no statistically significant impact on students’ attitudes toward mathematics and technology. Researchers also collected observation and interview data on teachers’ instructional practices. These data suggest that many teachers had difficulty implementing the treatment curriculum's learner-centered pedagogy. In fact, observed levels of learner-centered practices were only modestly higher in treatment classes than in control classes. In both treatment and control classes, however, higher levels of learner-centered pedagogy were associated with higher student achievement in geometry.  相似文献
