This study is a follow-up to one published in computer science education in 2010 that reported preliminary results showing a positive impact of service learning on student attitudes associated with success and retention in computer science. That paper described how service learning was incorporated into a computer science course in the context of the Students & Technology in Academia, Research, and Service (STARS) Alliance, an NSF-supported broadening participation in computing initiative that aims to diversify the computer science pipeline through innovative pedagogy and inter-institutional partnerships. The current paper describes how the STARS Alliance has expanded to diverse institutions, all using service learning as a vehicle for broadening participation in computing and enhancing attitudes and behaviors associated with student success. Results supported the STARS model of service learning for enhancing computing efficacy and computing commitment and for providing diverse students with many personal and professional development benefits.  相似文献

In reform-based science curricula, students’ discursive participation is highly encouraged as a means of science learning as well as a goal of science education. However, Asian immigrant students are perceived to be quiet and passive in classroom discursive situations, and this reticence implies that they may face challenges in discourse-rich science classroom learning environments. Given this potentially conflicting situation, the present study aims to understand how and why Asian immigrant students participate in science classroom discourse. Findings from interviews with seven Korean immigrant adolescents illustrate that they are indeed hesitant to speak up in classrooms. Drawing upon cultural historical perspectives on identity and agency, this study shows how immigrant experiences shaped the participants’ othered identity and influenced their science classroom participation, as well as how they negotiated their identities and situations to participate in science classroom and peer communities. I will discuss implications of this study for science education research and science teacher education to support classroom participation of immigrant students.  相似文献

This study aimed to examine whether the relationships among family resources, school climate, learning participation, science attitude, and science achievement are different between primary school students and junior high school students within one educational system. The subjects included 4,181 Grade 4 students and 5,074 Grade 8 students who participated in TIMSS 2003 in Taiwan. Using structural equation modeling, the results showed that family resources had significant positive effects for both groups of learners. Furthermore, a context effect for the structural relationship between school climate, learning participation, and science achievement was revealed. In the primary school context, Grade 4 students who perceived positive school climate participated in school activities more actively, and had better science performance. However, in the secondary school context, learning participation had a negative impact and led to lower science achievement. The implications about this result in relation to the characteristics of the two educational contexts in Taiwan were further discussed.  相似文献

It is a common view that developing teachers’ competence to restructure or reframe their knowledge and beliefs is inevitably a complex challenge. This paper reports on a research project with the aim to develop science teachers’ pedagogical content knowledge (PCK) through their participation in a learning study. A learning study is a collegial process in which teachers work together with a researcher to explore their own teaching activities in order to identify what is critical for their students’ learning. During one semester, three secondary science teachers worked in a learning study together with a researcher in a cyclical process in order to create prerequisites and further identify conditions for students’ learning. During the learning study, data were collected from video-recorded lessons and stimulated recall sessions in which the teachers and the researcher reflected on the lessons to analyze their development of PCK, their students’ learning and the impact of that knowledge on their own teaching. The results provide an insight into how the teachers developed their self-understanding in which they questioned their own epistemological beliefs, aims and objectives of teaching and taken-for-granted assumptions about science teaching and learning. As such, the study provides an understanding of teacher professional learning through a careful investigation of how teachers’ PCK is enhanced through their participation in the learning study, and further, how students’ learning might be developed as a consequence.  相似文献

This study investigates classroom organisation and interaction focusing on phases of activity. The detailed in-depth case study is based on video recordings of 1 science unit consisting of 11 lessons about biological evolution in a Swedish ninth-grade class (aged 15). The study illuminates the temporality of student participation as a fundamental and practical concern for the science teaching profession. Through multiple scale analysis an activity pattern and students' contrasting positions are identified. Movements of control and agency between teacher and students in small-groups provide opportunities for the teacher to coordinate the teaching and the pace of students' participation. The implications point to challenges involved in providing all students with the learning opportunities that participation in the school science discourse affords.  相似文献

This case study reports on patterns of participation in a virtual collaboratory organised around goals associated with the involvement of graduate students in research and writing projects. Traditionally, distance learning classrooms have been devoted to teaching content matter (in a virtual context) yet this case study reports on the use of synchronous learning contexts to support research and professionalisation on the part of graduate students in library and information science. Focus is placed on discussing virtual collaboratories as a form of learning design that modifies the use of existing (synchronous) distance learning classrooms.  相似文献

ABSTRACT

Reading is a tool that promotes the learning of science across schooling. Scientific texts are conceptually and linguistically complex, especially for students from low-income contexts because they have neither the experience with the language nor the literacy skills to face the challenges of scientific knowledge. This study used a mix method approach to compare the cognitive scaffolding practiced by teachers during science reading activities in high- and low-performing schools. Three teachers and 141 fourth grade students from low socioeconomic background schools participated in 48 class sessions. Classes were video-recorded and transcribed. The data were analyzed using Sanchez’ Pedagogic Practice Analysis System. The results show that teachers from both types of schools continuously use reading as a tool for learning. The effective teacher uses reading with non-invasive scaffolding and varied verbal participation to elaborate knowledge, promoting literal and inferential comprehension and more opportunities for the students to construct knowledge. By contrast, less effective teachers use reading with invasive scaffolding and little verbal participation of the students to consolidate knowledge, promoting mainly literal comprehension. This study shed light on different approaches teachers use to foster reading comprehension for science learning.  相似文献

This study investigates the impact of participation in the CREativity in Science and Technology (CREST) programme on student self-regulated processes and related motivations. The CREST scheme, a student-run science project managed by the British Science Association, is currently being implemented in schools across the UK to increase student engagement and motivation in science. Through implementing a rigorous quasi-experimental research design using two intervention conditions and one control group with immediate as well as 3-month delayed post-test data, the results documented both the immediate and longer-term positive impact of CREST participation on students’ self-reported levels of self-regulation. The present study also investigates changes in teachers’ perceptions of students’ self-regulated learning through CREST programme participation. Group differences regarding changes in student self-reported self-regulation were not matched when looking at the teacher-reported self-regulated learning results at both immediate post-test and delayed post-test. These discrepancies are discussed in relation to analyses conducted on the other motivational constructs measured.

Contemporary research into science education has generally been conducted from the perspective of ‘conceptual change’ in learning. This study sought to extend previous work by recognizing that human rationality can be influenced by the emotions generated by the learning environment and specific actions related to learning. Methods used in educational psychology were adopted to investigate the emotional experience of science students as affected by gender, teaching methods, feedback, and learning tasks. A multidisciplinary research approach combining brain activation measurement with multivariate psychological data theory was employed in the development of a questionnaire intended to reveal the academic emotions of university students in three situations: attending science class, learning scientific subjects, and problem solving. The reliability and validity of the scale was evaluated using exploratory and confirmatory factor analyses. Results revealed differences between the genders in positive-activating and positive-deactivating academic emotions in all three situations; however, these differences manifested primarily during preparation for Science tests. In addition, the emotions experienced by male students were more intense than those of female students. Finally, the negative-deactivating emotions associated with participation in Science tests were more intense than those experienced by simply studying science. This study provides a valuable tool with which to evaluate the emotional response of students to a range of educational situations.  相似文献

Undergraduates entering science curricula differ greatly in individual starting points and learning needs. The fast pace, high enrollment, and high stakes of introductory science courses, however, limit students' opportunities to self-assess and modify learning strategies. The University of Washington's Biology Fellows Program (BFP) intervenes through a 20-session, premajors course that introduces students to the rigor expected of bioscience majors and assists their development as science learners. This study uses quantitative and qualitative approaches to assess whether the 2007-2009 BFP achieved its desired short- and long-term impacts on student learning. Adjusting for differences in students' high school grade point average and Scholastic Aptitude Test scores, we found that participation in the BFP was associated with higher grades in two subsequent gateway biology courses, across multiple quarters and instructors. Two to 4 yr after participating in the program, students attributed changes in how they approached learning science to BFP participation. They reported having learned to "think like a scientist" and to value active-learning strategies and learning communities. In addition, they reported having developed a sense of belonging in bioscience communities. The achievement of long-term impacts for a short-term instructional investment suggests a practical means to prepare diverse students for the rigors of science curricula.  相似文献

The constructivist learning approach is suggested as a means for facilitating students’ learning of science and increasing their participation in this learning. Several studies have shown the contribution of this approach to the different aspects of students’ learning of science, though little research has examined the contribution of this approach to the democratic environment of the science classroom. The present study attempted to do so. 34 grade 5 science students studied the energy unit of the science book using the V-shape strategy, and 38 grade 5 science students studied the same unit without using the strategy. The research results show that students who used the V-shape strategy had significantly higher scores in democratic practices than students who did not use the strategy. Moreover, the democratic practices in the science classroom were not influenced significantly by the independent variables (science ability, general ability, and preferred subject). The results of the current study also show that, in the experimental group, only the correlation between involvement and freedom was significant, while in the control group, all of the correlations among involvement, freedom, and equality were significant.  相似文献

This paper analyzes teaching and learning in urban science classrooms in which most of the students are African American and from low-income homes. Their teachers are also racial minorities and yet they struggle to teach successfully across cultural boundaries. The first set of case studies involves a male teacher who taught in a high-energy way that produced structures for students to get involved in the doing of science. His verbal fluency and expressive individualism, involving emphatic gestures, rhythmic use of his body, and voice intonation maintained student participation. A second case study examines successful interactions among the students, involving an argument over competing models for chemical valence. Whereas the students interacted successfully, the teacher was frequently out of synchrony in terms of amplitude, pitch, and non-verbal actions. The key implication is the necessity for teachers and students to learn how to interact successfully in ways that produce positive emotional energy, a sense of belonging to the class, and a commitment to shared responsibility for one another's participation. Aligning the cultures of teaching and learning offers a possibility that fluent interactions will occur, afford success, and facilitate the learning of science.  相似文献

Abstract

Citizen science is a valuable tool in environmental and formal education in creating scientific knowledge for the researchers and facilitating learning and fostering a positive relationship toward the environment and study species. We present a case study on the Helsinki Urban Rat Project in which students surveyed rat occurrence in their own near environments. According to our results, experientiality, involvement, meaningfulness, freedom to choose, ease of participation, and the rats themselves contributed to students’ increased interest in participation. Furthermore, students described diverse factual, conceptual, procedural, and metacognitive knowledge that they acquired during their participation. In general, students described negative attitudes toward rats, but they less negative views on rats after participation. We reflect on the success of the citizen science project and implications of planning a future citizen science project and incorporating citizen science in formal education.  相似文献

The development of scientifically literate citizens remains an important priority of science education; however, growing evidence of students' disenchantment with school science continues to challenge the realization of this aim. This triangulation mixed methods study investigated the learning experiences of 152 9th grade students as they participated in an online science‐writing project on the socioscientific issue of biosecurity. Students wrote a series of hybridized scientific narratives, or BioStories, that integrate scientific information about biosecurity with narrative storylines. The students completed an online Likert‐style questionnaire, the BioQuiz, which examined selected aspects of their attitudes toward science and science learning, prior to their participation in the project, and upon completion of the writing tasks. Statistical analyses of these results and interview data obtained from participating students suggest that hybridized writing about a socioscientific issue developed more positive attitudes toward science and science learning, particularly in terms of the students' interest and enjoyment. Implications for research and teaching are also discussed. © 2011 Wiley Periodicals, Inc. J Res Sci Teach 48: 878–900, 2011  相似文献

Previous research on science education has described various factors influencing students’ participation and produced categorizations of students based on e.g. cultural background. In this article it is argued, theoretically and empirically, that an understanding of students’ participation in science education needs to begin with an analysis of what activity students are engaged in. The aim is to explore how altering conditions of classroom work may open up opportunities for students mainly participating in an activity of education or schooling to engage in an activity of science learning. Activity is conceptualized in a Cultural-Historical Activity Theory perspective as object-oriented and transformative. Drawing on an ethnographic study in a Swedish compulsory school, a critical incident of the participation in science education of a 7th grade girl called Helena is analyzed. The results show that altered conditions of classroom practice may produce new possibilities for student participation, and point to the impossibility of determining students as ‘different kinds of students’ based on a priori categories e.g. sex, ethnicity, socio-economic background.  相似文献

Bilingual and multilingual speakers mix two or more languages for communication, gaining information and sense-making in varieties of contexts. How do bilinguals mix languages and what does the mixing afford for their learning and participation? This study examines these questions, focusing on Korean-English bilingual youths in a community-based after-school science programme in the United States. A close analysis of videorecordings of the programme sessions demonstrates the ways in which bilinguals negotiate their participant positions and negotiate meanings in their study of science topics. The findings reveal that bilinguals utilise their Korean proficiency to craft diverse ways of participation and that linguistic and scientific sense-making co-occur and support each other. Based on these findings, I offer implications as to how science teachers should perceive students’ mixing of multiple languages and how they can support bilinguals’ learning of science content and English. Additionally, I suggest a future research direction that can help teachers to prepare for linguistically diverse science-learning and -teaching contexts.  相似文献

Science education models for secondary and college students as well as K‐12 teachers have been dominated by classroom‐based approaches. Recently, research apprenticeships wherein learners worked with practicing scientists on authentic scientific research have become increasingly popular. The purpose of this critical review of the literature was to review and synthesize empirical studies that have explored learning outcomes associated with research apprenticeships for science learners. We reviewed 53 studies of scientific research apprenticeship experiences for secondary students, undergraduates and teachers, both pre‐service and in‐service. The review explored various learning outcomes associated with participation in research apprenticeships. These outcomes included effects of apprenticeship experiences on participant career aspirations, ideas about the nature of science (NOS), understandings of scientific content, confidence for doing science and intellectual development. The extant literature supported many of the presumed positive associations between apprenticeship experiences and desired learning outcomes, but findings related to some themes (e.g., NOS understandings) supported conflicting conclusions. Implications included importance of the length of the apprenticeship, need to explicitly place attention on desired outcomes, and engagement of participants. © 2009 Wiley Periodicals, Inc.

The purpose of this study was to investigate primary students’ learning through participation in an out‐of‐school enrichment programme, held in a science centre, which focused on DNA and genes and whether participation in the programme led to an increased understanding of inheritance as well as promoted interest in the topic. The sample consisted of two groups (245 students in the experimental group and 150 students in the control group) of upper primary students (Grade 5) from six schools in Singapore. Two instruments were developed—a 15‐item multiple‐choice test to measure learning gains and a 17‐item survey form to measure student feedback. Pre‐, post‐, and delayed post‐tests were administered. Results showed statistically significant gains in learning for the experimental group that appeared to be stable as well as high levels of interest stimulated by the programme.  相似文献
