Background: For the past decade, science educators have been exploring the use of Socio-scientific Issues (SSI) as contexts for science teaching and learning, and research indicates that doing so can support significant learning gains. However, research related to how teachers take up the practice of SSI-based instruction is far more limited, due in part to a lack of tools for use in this kind of research.

Purpose: The focus of this research is development and testing of a new classroom observation protocol specifically designed for SSI-based instructional contexts.

Design and methods: Development of this SSI-Observation Protocol (SSI-OP) took place in four distinct phases: review of existing protocols and SSI-based instruction frameworks, writing and revision of protocol items, initial testing of the draft protocol, and soliciting feedback from SSI experts.

Sample: Following the four stages of SSI-OP development, we progressed to a series of field tests. The field tests were conducted with three different samples. The first sample was an experienced (10 + years) high school biology teacher and one of her honors biology classes. The second sample consisted of seven Turkish Pre-service Science Teachers (PST) participating in a science methods course. The third sample included two Thai PST from a field experience course embedded within a teacher education program.

Results: The final version of the protocol addressed five dimensions of SSI-based instructional activities: focus of instruction, teaching moves, role of teacher, role of students, and classroom environment.

Conclusions: The SSI-OP could be used in a variety of ways for research including documentation of current practices, impacts of professional development and/or curricula on teaching practices, and changes in teaching over time. We offer the SSI-OP as a new tool with the potential to contribute to science teacher education and research that may advance the teaching and learning of science through SSI.  相似文献

Ongoing work in Andhra Pradesh Primary Education Project (APPEP) (Southern India) has resulted in the production of a new Class 1 textbook, teacher textbook and eight supplementary readers. These important and innovative new classroom materials have been produced as a result of training and workshops involving resource persons from the Telugu Academy, Telugu University, State Centre for Educational Research and Training and lecturers in District Institutes of Education and Training. Additionally, for the first time, primary school teachers were co‐opted on an equal basis to work on the materials.

The textbook, which constitutes the only learning material in Class One, is designed to teach children to read and write in Telugu. Previous research showed that children at the end of Class 2 were mostly unable to identify letters or words out of the context and order in which they appeared in the textbook. The current state textbook was basically a writing primer, teaching writing in alphabetic order with reading rarely going beyond single words or sentences.

The new textbook incorporates the necessary ‘reading context’ using rhymes, short stories and dialogue to encourage shared reading with the teacher before individual letters are learned. The order of introduction of the letters for writing has been based on research showing generalisable shapes in letters; alphabetic order is learned as a separate item. The pictures in the book were designed to promote discussion and develop prediction and an understanding of story structure. The content was matched to the child's developmental and psychological needs.

The teacher textbook incorporates ideas for extending learning into activities and exercises and consists of the children's textbook interleaved with teacher guidance. The evaluation shows that this teacher guidance has been used and valued by the teachers.

The eight supplementary readers are at four levels. Level One is for shared reading with the teacher and includes folk stories, songs and a story about a family. Level Two are picture books with simple captions and sentences using only the letters and words already learned by the child. Level Three progresses to more extensive stories including some information based stories. Level Four revisits Level One for independent reading of the same books.

The books have been trialled in 50 sample schools matched on a number of variables to 50 control schools. A pre‐reading test was administered to all children and a post‐reading test measured learning gains. Case studies of the books in use in classrooms were also undertaken. The evaluation to date shows significant learning gains amongst the children in the sample schools, a high degree of teacher satisfaction and interest and approval from parents and children. A resource team including teachers has been trained for further renewal of textbooks throughout the primary years.

This work has been funded by the Overseas Development Administration and they will fund the provision of eight supplementary readers in all Class One in schools throughout the state in 1996. After revision the textbook will be implemented by the Government of Andhra Pradesh.  相似文献

Background: This study is the second study of a design-based research, organised around four studies, that aims to improve student learning, teaching skills and teacher training concerning the design-based learning approach called Learning by Design (LBD).

Purpose: LBD uses the context of design challenges to learn, among other things, science. Previous research shows that this approach to subject integration is quite successful but provides little profit on (scientific) concept learning. For this, a lack of (knowledge of) proper teaching strategies is suggested as an important reason. This study explores these strategies and more specific the interaction with concept learning.

Sample: Six Dutch first-year bachelor’s degree science student teachers, between the ages of 16 and 18, and two science teacher trainers (principal investigators included) were involved.

Design and methods: A mixed methods study was used to study LBD’s teaching practice in depth. Based on a theoretical framework of (concept) learning-related teaching strategies video recordings of a guided LBD challenge were analysed to unravel teacher handling in detail. Complemented by questionnaire and interview data and students’ learning outcomes (pre- and post-exam) the effectiveness of teaching strategies was established and shortcomings were distracted.

Results: Students reached medium overall learning gains where the highest gains were strongly task-related. Teacher handling was dominated by providing feedback and stimulating collaboration and only 13% of all teacher interventions concerned direct explication of underlying science. And especially these explicit teaching strategies were highly appreciated by students to learn about science.

Conclusions: In accordance with insights about knowledge transfer, LBD needs to be enriched with explicit teaching strategies, interludes according to poor-related science content important for cohesive understanding and de- and recontextualisation of concepts for deeper understanding.  相似文献

Background: Technological pedagogical content knowledge (TPACK) is critical for effective teaching with technology. However, generally science teacher education programs do not help pre-service teachers develop TPACK.

Purpose: The purpose of this study was to assess pre-service science teachers' TPACK over a semester-long Science Methods.

Sample: Twenty-seven pre-service science teachers took the course toward the end of their four-year teacher education program.

Design and method: The study employed the case study methodology. Lesson plans and microteaching observations were used as data collection tools. Technological Pedagogical Content Knowledge-based lesson plan assessment instrument (TPACK-LpAI) and Technological Pedagogical Content Knowledge Observation Protocol (TPACK-OP) were used to analyze data obtained from observations and lesson plans.

Results: The results showed that the TPACK-focused Science Methods course had an impact on pre-service teachers’ TPACK to varying degrees. Most importantly, the course helped teachers gain knowledge of effective usage of educational technology tools.

Conclusion: Teacher education programs should provide opportunities to pre-service teachers to develop their TPACK so that they can effectively integrate technology into their teaching.  相似文献

Background: Inquiry learning in science provides authentic and relevant contexts in which students can create knowledge to solve problems, make decisions and find solutions to issues in today’s world. The use of electronic networks can facilitate this interaction, dialogue and sharing, and adds a new dimension to classroom pedagogy.

Purpose: This is a report of teacher and student reflections on some of the tensions, reconciliations and feelings they experienced as they worked together to engage in inquiry learning. The study sought to find out how networked ICT use might offer new and different ways for students to engage with, explore and communicate science ideas within inquiry.

Sample: This project developed case studies with 6 science teachers of year 9 and 10 students, with an average age of 13 and 14 years in three New Zealand high schools. Teacher participants in the project had varying levels of understanding and experience with inquiry learning in science. Teacher knowledge and experience with ICT were equally diverse.

Design and Methods: Teachers and researchers developed initially in a joint workshop a shared understanding of inquiry, and how this could be enacted. During implementation, the researchers observed the inquiry projects in the classrooms and then, together with the teachers, reviewed and analysed the data that had been collected.

Results: At the beginning of the project, some of the teachers and students were tentative: inquiry based teaching supported by ICT meant initially that the teachers were hesitant in letting go some of the control they felt they had over students learning, and the students felt insecure in adopting some responsibility for their own learning. Over time a sense of trust and ease developed and this ‘control of learning’ balance moved from what was traditionally accepted, but not without modifications and reservations.

Conclusions: There is no clear pathway to follow in moving towards ICT-supported science inquiry in secondary schools. The experience of the teacher, the funds of knowledge the students bring to the classroom, the level of technological availability in the school and the ability of the students are all variables which determine the nature of the experience.  相似文献

Background: From previous research among science teachers it is known that teachers’ attitudes to their subjects affect important aspects of their teaching, including their confidence and the amount of time they spend teaching the subject. In contrast, less is known about technology teachers’ attitudes.

Purpose: Therefore, the aim of this study is to investigate Swedish technology teachers’ attitudes toward their subject, and how these attitudes may be related to background variables.

Sample: Technology teachers in Swedish compulsory schools (n = 1153) responded to a questionnaire about teachers’ attitudes, experiences, and background.

Methods: Exploratory factor analysis was used to inwvestigate attitude dimensions of the questionnaire. Groupings of teachers based on attitudes were identified through cluster analysis, and multinomial logistic regression was performed to investigate the role of teachers’ background variables as predictors for cluster belonging.

Results: Four attitudinal dimensions were identified in the questionnaire, corresponding to distinct components of attitudes. Three teacher clusters were identified among the respondents characterized by positive, negative, and mixed attitudes toward the subject of technology and its teaching, respectively. The most influential predictors of cluster membership were to be qualified for teaching technology, having participated in in-service-training, teaching at a school with a proper overall teaching plan for the subject of technology and teaching at a school with a defined number of teaching hours for the subject.

Conclusions: The results suggest that efforts to increase technology teachers’ qualifications and establishing a fixed number of teaching hours and an overall teaching plan for the subject of technology may yield more positive attitudes among teachers toward technology teaching. In turn, this could improve the status of the subject as well as students’ learning.  相似文献

Background and purpose: To date, there has been little research on the Teacher Professional Development (TPD) for delivering a mobile technology-supported science curriculum. To address this, a TPD model for a science curriculum supported by mobile technology was developed and evaluated in this paper. The study reported focuses on the establishment of the TPD model and exploration of its impact on teacher behaviors in the curriculum implementation.

Sample, design, and methods: In the study, two representative science teachers’ implementation of the science curriculum was presented together with an in-depth study of the TPD sessions. The data from the teacher-led PD working sessions, classroom observation and teacher interview were collected. Mixed methods and case study were used to analyze the teacher performance on the PD working sessions and on the curriculum implementation.

Results: Our findings suggested that teachers benefited from the structured TPD which provided opportunities for sharing, extensive feedback, and reflection of the curriculum implementation. It showed that teachers had transformed questioning from traditional ways into constructivist-oriented patterns in the classroom. More student-centered activities were conducted and complemented with teachers’ various scaffolds for learning. Analysis of learning artifacts attested to improvements in students’ conceptual understanding of science.

Conclusion: TPD refers to a continuing and dynamic system for PD which needs to be changed and elaborated based on teacher needs, school context and the problems and challenges encountered in the teaching practice. TPD development and teachers’ growth in the belief and competences on the instruction constitute a mutual evolution process. Their evolution could guarantee the apt enactment and spread of the curriculum innovation to impact depth, to sustain and to spread.  相似文献

Background Argumentation is an important discourse process in science that needs to be taught and learned as part of a repertoire of strategies to support the acquisition of scientific literacy. Research in science education indicates that beliefs or perceptions and the epistemological orientations of teachers influence their approaches to science teaching.

Purpose The paper aims to illustrate primary pre-service teachers’ understanding of argumentation based on a study using quantitative methodology. In particular, it aims to illustrate how these teachers view quality of arguments and teaching strategies related to argumentation in the context of a socio-scientific issue on energy.

Sample 332 pre-service teachers enrolled in a university teacher education programme in Spain were investigated. Many studies on argumentation have been conducted with small sample sizes of teachers. Hence, given the sample size, the study provides findings that are likely to be generalisable.

Design and methods A questionnaire was administered to the participants. The design of the questionnaire was guided by some existing analytical tools which were adapted for primary education purposes in the context of socio-scientific issues. This adaptation is novel in that the questionnaire items can potentially be used as diagnostic questions to assess primary teachers’ understanding of argumentation.

Results The results suggest that pre-service teachers had difficulty in understanding arguments and different pedagogical strategies to promote argumentation in classroom. For example, they did not understand the role and the meaning of warrants in scientific arguments and their understanding of the use of different kind of strategies is limited to debates, open discussions and experiments. The age range of the participants and the length of teaching experience had no impact on the quality of their understanding of argumentation.

Conclusions Pre-service science teacher education will benefit from incorporation of more robust and lengthy sessions on argumentation. For example, sessions could focus on quality as well as structure of arguments in science and more diverse pedagogical strategies to support argumentation in science lessons, such as the use of writing frames and presentations.  相似文献

Background: The development of primary pre-service teachers’ chemistry motivation and attitudes toward chemistry were examined in order to develop their science literacy using case-based learning. Students’ ideas were emphasized, real-life situations were discussed, and students could share their ideas and knowledge with peers; as a result, students were active in the learning process.

Purpose: The purpose of the study was to investigate the effectiveness of using case-based learning instruction to increase pre-service primary teachers’ chemistry motivation and improve their attitudes toward chemistry as a school subject.

Sample: The subjects of this study consisted of 51 (20 female, 31 male) freshman primary pre-service teachers from an urban university in Turkey. The mean age of the primary pre-service teachers was 21.

Design and methods: One group pre-test and post-test design was used. A chemistry motivation questionnaire and chemistry attitude scale were used for data collection. For the data analysis, two-way repeated measures of ANOVA and repeated measures MANOVA were conducted.

Results: The results indicated that the mean of the attitude score after the treatment was significantly greater than the mean of the attitude before the treatment. The results also demonstrated that there is no significant difference between females and males. According to the results of the study, there is no significant difference between primary pre-service teachers’ chemistry motivation. However, some chemistry motivation constructs mean scores are greater after the treatment.

Conclusions: In sum, it could be stated that case-based learning is helpful for the development of students’ chemistry motivation and attitudes toward chemistry.  相似文献

Purpose: School principals must determine educational policies and make information-based decisions. Teachers have authentic information that they do not transmit in full to the principals. A theoretical model was tested that explains the factors behind this disconnection in communication.

Design: Four hundred and forty-five teachers completed questionnaires that examined a variety of aspects of reciprocal relations between teachers and school management.

Findings: The model explains 44% of the variance in authentic teacher–principal communication. The principal’s communication pattern with teachers, with two sub-components, represents a dominant factor in teacher willingness to share information. Leadership style represents only an indirect factor.  相似文献

Background Global climate change (GCC) has become one of the most debated socio-scientific issues after an increase in media attention. Recently, there have also been several studies describing students’ and teachers’ alternative conceptions about GCC. Therefore, designing learning environments at the college level that focus on accurate conceptions of GCC has become important in order for pre-service teachers to correct their alternative conceptions. There are, however, a limited number of studies that aim to both increase pre-service teachers’ knowledge about these issues and explore their perceptions of teaching this subject.

Purpose The purpose of this study was to investigate the effects of inquiry-based activities on pre-service teachers’ knowledge about GCC and their perceptions of teaching this subject.

Sample The participants were 102 pre-service middle school mathematics and science teachers who were enrolled in an environmental education course.

Design and methods A one group pre-test–post-test design was employed to identify changes after pre-service teachers engaged in a learning unit on GCC. The inquiry-based GCC unit was implemented during the spring semester at a public university in northeastern Turkey. The unit was implemented over seven sessions. Data were collected through two questionnaires: the ‘GCC content questionnaire’ and the ‘perceptions of teaching GCC questionnaire’. Each questionnaire was administered both before and after implementation of the unit. Content questionnaire responses were analyzed using a paired-samples t-test. Responses to the perceptions of teaching questionnaire were analyzed using inductive open coding.

Results Results indicated that after the implementation the pre-service teachers significantly improved their understanding of GCC across all items in the content questionnaire, saw several benefits of and challenges about teaching GCC, and perceived themselves as better prepared to teach about GCC in their future classrooms.

Conclusions Teacher education programs should integrate inquiry-based GCC instruction to increase pre-service teachers’ knowledge as well as their preparedness to teach about this important planetary issue.  相似文献

The subject of the study comprised individual differences of creative achievements among 6‐year‐old children in two basic and qualitatively different kinds of child's activity: verbal and artistic. The aim of the research was both the analysis of the creative capacity level differentiation and pointing out the hierarchy of factors which determine certain inter‐ and intra‐individual as well as inter‐ and intro‐group differences.

The study is based on the concepts of the creativity theory of Wallach and Kogan (1970) and the capacity theory of Renzulli (1986) and Monks (1981) developed within the framework of humanistic and cognitive psychology.

The researcher analysed 6,000 drawings and the same number of oral statements produced by 643 children attending two types of pre‐schools and living in three different habitats. The research also covered teachers working with the 6‐year‐old children.

The following were used in the study: the test ‘Draw‐a‐Man’ of Goodenough; Guilford's tests of divergent thinking; Uszynska's Questionnaire of self‐estimation; The Schaefer's and Aaronson's Classroom Behaviour Inventory Pre‐school to Primary Scale; Popek's Questionnaire of Creative Behaviour ‘KANH’, and Uszynska's Questionnaire for parents.

The results of the research confirm a great differentiation of creative capacity levels of children and suggest that the most significant factors determining them are the pedagogic ones, which may directly or indirectly be influenced by the preschool teacher.  相似文献

Background: Reading is an interactive and constructive process of making meaning by engaging a variety of materials and sources and by participating in reading communities at school or in daily life.

Aim: The purpose of this study was to explore the factors affecting digital reading literacy among upper-elementary school students.

Method: A 3-stage stratified cluster sampling was implemented that resulted in a sample of 592 upper-elementary students from 29 classes in 7 schools. Self-Regulated Learning Strategies Assessment (S-RLSA), Digital Reading Literacy Assessment (DRLA), and student reports of their parents’ education backgrounds were used to collect data on the outcome and predictor variables. Interpretation of these data involved two highly regarded statistical techniques. First, structural equation modeling was used to explore relationships amongst the constructs. Second, multi-group invariance (MI) analyses were used to assess the influence of parental education and self-regulated learning strategies on students’ digital reading literacy.

Results: Enriching students’ family learning resources and strengthening their self-regulated learning abilities could have very important influences on promoting upper-elementary school students' digital reading literacy -webpage information retrieval, reading and communication abilities.

Conclusions: This study also provides information on how teachers can address student resources to improve digital reading literacy and self-regulated strategies.  相似文献

Background: Textbooks are integral tools for teachers’ lessons. Several researchers observed that school teachers rely heavily on textbooks as informational sources when planning lessons. Moreover, textbooks are an important resource for developing students’ knowledge as they contain various representations that influence students’ learning. However, several studies report that students have difficulties understanding models in general, and chemical bonding models in particular, and that students’ difficulties understanding chemical bonding are partly due to the way it is taught by teachers and presented in textbooks.

Purpose: This article aims to delineate the influence of textbooks on teachers’ selection and use of representations when teaching chemical bonding models and to show how this might cause students’ difficulties understanding.

Sample: Ten chemistry teachers from seven upper secondary schools located in Central Sweden volunteered to participate in this study.

Design and methods: Data from multiple sources were collected and analysed, including interviews with the 10 upper secondary school teachers, the teachers’ lesson plans, and the contents of the textbooks used by the teachers.

Results: The results revealed strong coherence between how chemical bonding models are presented in textbooks and by teachers, and thus depict that textbooks influence teachers’ selection and use of representations for their lessons. As discussed in the literature review, several of the selected representations were associated with alternative conceptions of, and difficulties understanding, chemical bonding among students.

Conclusions: The study highlights the need for filling the gap between research and teaching practices, focusing particularly on how representations of chemical bonding can lead to students’ difficulties understanding. The gap may be filled by developing teachers’ pedagogical content knowledge regarding chemical bonding and scientific models in general.  相似文献

This presentation looks at how young children learn basic geometrical concepts. Piaget's developmental levels will be examined to determine how they fit into the current research project. These will be compared with materials from the Soviet States that have recently become available from the NCTP in the USA.

The research project was constructed in a number of early childhood centres in a variety of socio‐economic areas. All of these centres had an early intervention program in operation so that special needs or ‘exceptional’ children could be observed along with mainstream children.

The researcher is investigating children's learning styles to determine the children's preferred learning styles when exploring spatial concepts. The question of whether exceptional children progress through the same stages and in the same order as the mainstream children is also being considered.

Spatial concepts in early childhood is an area that seems to have been neglected by researchers in favour of the development of number concepts. This research project aims to add to our knowledge of how young children learn spatial concepts.

Background: Complexity models have provided a suitable framework in various domains to assess students’ educational achievement. Complexity is often used as the analytical focus when regarding learning outcomes, i.e. when analyzing written tests or problem-centered interviews. Numerous studies reveal negative correlations between the complexity of a task and the probability of a student solving it.

Purpose: Thus far, few detailed investigations explore the importance of complexity in actual classroom lessons. Moreover, the few efforts made so far revealed inconsistencies. Hence, the present study sheds light on the influence the complexity of students’ and teachers’ class contributions have on students’ learning outcomes.

Sample: Videos of 10 German 8th grade physics courses covering three consecutive lessons on two topics each (electricity, mechanics) have been analyzed. The sample includes 10 teachers and 290 students.

Design and methods: Students’ and teachers’ verbal contributions were coded manual-based according to the level of complexity. Additionally, pre-post testing of knowledge in electricity and mechanics was applied to assess the students’ learning gain. ANOVA analysis was used to characterize the influence of the complexity on the learning gain.

Results: Results indicate that the mean level of complexity in classroom contributions explains a large portion of variance in post-test results on class level. Despite this overarching trend, taking classroom activities into account as well reveals even more fine-grained patterns, leading to more specific relations between the complexity in the classroom and students’ achievement.

Conclusions: In conclusion, we argue for more reflected teaching approaches intended to gradually increase class complexity to foster students’ level of competency.  相似文献

Background: In recent research, affective learning environments and affective support have been receiving increasing attention for their roles in stimulating students’ learning outcomes. Despite its raising importance, little is known about affective support in educational contexts in developing countries. Moreover, international student assessment programmes (e.g. PISA and TIMSS) reveal poor science proficiency of students in most of those countries, which provokes the question of how to make positive changes in students’ perspectives and attitudes in science.

Purpose: In the current study, the purpose was to investigate the relations among perceived teacher affective support (PTAS), academic emotions (academic enjoyment, academic anxiety, and academic hopelessness), academic self-efficacy and behavioural engagement in elementary school science classrooms in Turkey.

Sample: A total of 633 fourth- and fifth-grade students in eight elementary schools in Istanbul, Turkey were participated in the study.

Design and methods: A self-report questionnaire was administered to participating students. The data were analysed using structural equation modelling.

Results: Findings showed that PTAS was both directly and indirectly related to the given variables. PTAS was found to be significantly positively associated with students’ academic enjoyment, academic self-efficacy and behavioural engagement and significantly negatively related to their academic anxiety and academic hopelessness in science classrooms. An important finding is that the total effect of PTAS on behavioural engagement, a factor strongly associated with academic success in all disciplines, was as strong as the effect of students’ perceived academic self-efficacy beliefs in science.

Conclusions: Findings suggest that PTAS may help promoting positive emotions and motivation among students in science classrooms, eventually leading to more desirable attitudes and achievement outcomes in science. Teacher affective support deserves greater recognition from researchers, educational policy-makers, administrators and teachers to build better learning conditions for all students.  相似文献
