There is an expectation that new science teachers will be able to effectively use a range of information communication technology (ICT) related resources inthe science classroom in order to enhance student learning. All school systems in Australia are in the process of providing teachers with ICT professional development and infrastructure. This paper outlines a range of initiatives designed to integrate ICT in a compulsory science education unit for students enrolled in a Graduate Diploma in Secondary Education. An action research model based on constructivist principles was used to evaluate the effectiveness of modelling, open-ended co-operative group activities and authentic assessment in enabling students to enhance their ICT skills, knowledge and pedagogical content knowledge in a science education context. Multiple sources of data were generated including a pre and post unit questionnaire that was analysed using Rasch modelling. The questionnaire determined students' perceptions of their preparedness to teach using ICT. The findings of this research suggest that some skills warranted greater attention in the unit, but students' pedagogical knowledge and knowledge and critique of ICT resources were enhanced over the duration of the unit.  相似文献

ABSTRACT

In Australia, the number of female graduates in some science, technology, engineering, and mathematics (STEM) disciplines is as low as 15%. Previous reviews exploring the issues affecting female undergraduate STEM students are primarily based in North America and there is yet to be an Australian focused review. This review identifies the factors contributing to the gendered experience of Australian undergraduate STEM students. A systematic review was conducted in November – December 2018 using ERIC, PsycInfo, ProQuest and Scopus databases. From this review, 36 papers that focus on gender differences and university STEM students in Australia were identified. The Australian research suggests the most prominent issue for female STEM students is their lower self-efficacy. Gendered preferences for learning, gendered motivations to pursue STEM degrees, the masculine culture of these fields and gender differences in science identity were also themes identified through the review. This review indicates some gaps in the Australian literature, namely that identity, and other emotional factors, are understudied in the Australian context and an avenue for future research. The findings suggest that science educators should be aware of the gendered experiences of their students to ensure female persistence in university STEM degrees.  相似文献

ABSTRACT

Background: Recent developments in STEM and computer science education put a strong emphasis on twenty-first-century skills, such as solving authentic problems. These skills typically transcend single disciplines. Thus, problem-solving must be seen as a multidisciplinary challenge, and the corresponding practices and processes need to be described using an integrated framework.

Purpose: We present a fine-grained, integrated, and interdisciplinary framework of problem-solving for education in STEM and computer science by cumulatively including ways of problem-solving from all of these domains. Thus, the framework serves as a tool box with a variety of options that are described by steps and processes for students to choose from. The framework can be used to develop competences in problem-solving.

Sources of evidence: The framework was developed on the basis of a literature review. We included all prominent ways of domain-specific problem-solving in STEM and computer science, consisting mainly of empirically orientated approaches, such as inquiry in science, and solely theory-orientated approaches, such as proofs in mathematics.

Main argument: Since there is an increasing demand for integrated STEM and computer science education when working on natural phenomena and authentic problems, a problem-solving framework exclusively covering the natural sciences or other single domains falls short.

Conclusions: Our framework can support both practice and research by providing a common background that relates the ways, steps, processes, and activities of problem-solving in the different domains to one single common reference. In doing so, it can support teachers in explaining the multiple ways in which science problems can be solved and in constructing problems that reflect these numerous ways. STEM and computer science educational research can use the framework to develop competences of problem-solving at a fine-grained level, to construct corresponding assessment tools, and to investigate under what conditions learning progressions can be achieved.  相似文献

This study focuses on the development of prospective computer engineers' knowledge of educational software design through their involvement in a constructivist learning environment emphasizing project based learning. Within this environment prospective computer engineers (PCE) adopted a variety of roles namely: learners, teachers, users, designers, implementers and evaluators of educational software dealing with concepts of computer science while also taking into account theoretical educational considerations regarding constructivism and social views of knowledge construction. The analysis of the data shows that PCE frequently start by considering traditional behavioristic views regarding teaching and learning as well as regarding the design of educational software. The PCE progressed to accept more constructivist views regarding teaching and learning as well as to designing educational software by communicating their knowledge with their colleagues and the teacher in the project based context. PCE also progressed through the evaluation of the educational software using real classrooms. By exploiting the given feedback, PCE improved the quality of software specifications.  相似文献

A teacher professional development program for in-service elementary school science teachers, the Rice Elementary Model Science Lab (REMSL), was developed for urban school districts serving predominately high-poverty, high-minority students. Teachers with diverse skills and science capacities came together in Professional Learning Communities, one full day each week throughout an academic year, to create a classroom culture for science instruction. Approximately 80 teachers each year received professional development in science content and pedagogy using the same inquiry-based constructivist methods that the teachers were expected to use in their classrooms. During this four-year study, scientists and educators worked with elementary teachers in a year-long model science lab environment to provide science content and science pedagogy. The effectiveness of the program was measured using a mix of quantitative and qualitative methods that allowed the researchers to triangulate the findings from quantitative measures, such as content test and surveys, with the emerging themes from the qualitative instruments, such as class observations and participant interviews. Results showed that, in all four years, teachers from the REMSL Treatment group have significantly increased their science content knowledge (p?<?0.05). During the last two years, their gains in science content knowledge, use of inquiry-based instruction and leadership skills were significantly higher than those of the Control group teachers' (p?<?0.01, p?<?0.001 and p?<?0.05, respectively). Three themes resonated in the interviews with participants: science content knowledge growth, constructivist pedagogy and leadership skills.  相似文献

A student-scientist partnership outreach program was funded by the U.S. National Aeronautics and Space Administration's Boreal Ecosystem-Atmosphere Study (BOREAS) to involve students and teachers in scientific investigations pertinent to global change research occurring within the boreal region of Canada. Boreal Forest Watch was planned, designed and piloted by an interdisciplinary group of education and science professionals from the University of New Hampshire, the Prince Albert National Park, and several schools in central Saskatchewan, Canada. A two goal approach was adopted to 1) ensure the educational significance of the program and 2) introduce scientifically valid methods for collection of research data pertinent to global change scientists. Professional educators and school administrators from Saskatchewan were recruited to assist in project planning to ensure that the proposed activities fit within the existing curriculum framework. This process was essential for successful adoption of the program by participating teachers. The process and approach of initiating Boreal Forest Watch are presented in this paper. This program became fully functional in September, 1996 with the training of several participating teachers. Perspectives of the program and its future are provided by members of the design team. Boreal Forest Watch is a unique opportunity for both Canadian students and their teachers to explore their natural environment, learn scientific methods and principles, and contribute data to the global change research community.  相似文献

Background: Problem-based learning (PBL) is a teaching approach working in cooperation with self-learning and involving research to solve real problems. The first law of thermodynamics states that energy can neither be created nor destroyed, but that energy is conserved. Students had difficulty learning or misconceptions about this law. This study is related to the teaching of the first law of thermodynamics within a PBL environment.

Purpose: This study examined the effectiveness of PBL on candidate science teachers’ understanding of the first law of thermodynamics and their science process skills. This study also examined their opinions about PBL.

Sample: The sample consists of 48 third-grade university students from the Department of Science Education in one of the public universities in Turkey.

Design and methods: A one-group pretest–posttest experimental design was used. Data collection tools included the Achievement Test, Science Process Skill Test, Constructivist Learning Environment Survey and an interview with open-ended questions. Paired samples t-test was conducted to examine differences in pre/post tests.

Results: The PBL approach has a positive effect on the students’ learning abilities and science process skills. The students thought that the PBL environment supports effective and permanent learning, and self-learning planning skills. On the other hand, some students think that the limited time and unfamiliarity of the approach impede learning.

Conclusions: The PBL is an active learning approach supporting students in the process of learning. But there are still many practical disadvantages that could reduce the effectiveness of the PBL. To prevent the alienation of the students, simple PBL activities should be applied from the primary school level. In order to overcome time limitations, education researchers should examine short-term and effective PBL activities.  相似文献

ABSTRACT

This paper describes a small scale research project to pilot the loan of portable computers to students and staff for use on or off‐campus. The purpose of the research is to identify organisational procedures and associated problems, find out how these portable computers are used, and whether or not they are an effective and efficient use of resources. Take‐up of the scheme in its first phase indicates popularity with students and positive outcomes. Very high use was recorded and many students report that use in their own time and in the atmosphere of their own surroundings encourages greater self‐confidence in information technology. They also consider that access to the portables has proved significant, with the quality of their work enriched. Such experiences raise important questions about the organisation of computing facilities and focus issues beyond the viability and economics of portable computer loan schemes. Within the outcomes of the project, there should be useful data pointing to the need to develop imaginative policies and funding models whereby each student can own or have ready access to their own personal computer. An important outcome of this could be the increased use of information technology by initial teacher education students, resulting in a corresponding increase in the transference of confidence, and use of information technology by children and other teachers in school.  相似文献

Computing is anticipated to have an increasingly expansive impact on the sciences overall, becoming the third, crucial component of a “golden triangle” that includes mathematics and experimental and theoretical science. However, even more true with computing than with math and science, we are not preparing our students for this new reality. It is appropriate and compelling therefore to consider how computer science can be fundamentally integrated into science education. This study is a ten-year review (1998–2008) of the Journal of Science Education and Technology, with the following research questions in mind: What are the intersections at the K-16 level between science and computing? What do K-16 science educators already know about the newly emerged field, computational science?  相似文献

This article discusses a project which has the goal of raising the awareness of pre-service teachers about the needs and potentials of low-income minority students through using technology to develop a comentoring community composed of teacher educators, teachers, pre-service students and elementary students. Using the interactive capabilities of video conferencing over the Internet, pre-service teachers engage in a 'virtual' field experience with a bilingual grade three classroom in a distant inner-city school. Pre-service teachers involved in the programme have the opportunity to be involved with students they would not experience in the local area, to be mentored by a teacher with knowledge of diversity, and to use technology in meaningful, productive ways. Benefits for participants—faculty, pre-service teachers, teachers in the school, and students in host classrooms—implications for pre-service teachers' understanding of diversity and limitations of the technology are discussed. 1  相似文献

Advanced educational technology promises to improve science teaching and learning. To achieve the posited outcomes, however, teachers must have access to, know how to, have the skills to, and want to use the proposed advanced educational technologies in their teaching. In response, for the past eight years with support from the National Science Foundation, BSCS has conductedENLIST Micros — a teacher development to help science teachers improve their use of microcomputers.ENLIST Micros has three phases — Phase one (1984–1986): BSCS designed, tested, and producedENLIST Micros (Ellis and Kuerbis, 1987, 1989) teacher development materials (text, video, and tutorial software) for helping science teachers improve their use of educational technology. Phase two (1986–1989): BSCS designed, developed, tested, and disseminated a staff development model for helping science teachers integrate educational technology into instruction. Phase three (1989–1992): BSCS established Teacher Development Centers to implement theENLIST Micros teacher development materials and staff development model with science teachers throughout the United States.ENLIST Micros has served more than 1500 science teachers in 15 states. Teachers who have participated in the program have improved their knowledge, attitude, and self-efficacy about computer usage and have improved their use of microcomputers in their science courses. Furthermore, as part of the project, BSCS has described the implementation process and has developed recommendations to support improvements in the use of educational technology in science programs.  相似文献

The science and technology education literature indicates that teaching within a constructivist paradigm is an effective way to promote student learning. Despite this, most primary school teachers do not use constructivist theoretical approaches because they are perceived as difficult and impractical to implement. To promote constructivist teaching and learning approaches in schools, teachers need access to models and strategies they can implement effectively and with relative ease. A unit of work was developed, based on the Five Es model (Engagement, Exploration, Explanation, Elaboration and Evaluation), and taught to a year 3 class. Ten students were participants in the study and became the sample. Data were analysed using two different methods to compare and validate findings. The unit of work, based on the Five Es model, was found to be interesting and fun by students, and motivated student learning and promoted student higher-order thinking.  相似文献

Abstract

This exploratory study aimed to describe the impact of the ‘Science in Family project’, as a transformative learning model for science teachers trying to improve student’s attitudes toward STEM subjects. This study took place in a public elementary school in Monterrey, Mexico, which has been developing this project for more than thirteen years with students from 4th, 5th and 6th grade. We used participant observation and interviews with four families whose children are students of this elementary school, and with one family whose sons were students of this school some years ago. Results showed that there is a relationship between positive attitudes towards science in students who were exposed to transformative learning models of teaching. Two of the participants took steps to follow science related careers. This study helps to illuminate the extent to which teacher education models influence students’ attitudes and how positive attitudes to science are influenced by the use of learning by doing projects.  相似文献

ABSTRACT

Previous research has documented that students who engage with socioscientific issues can acquire some of the complex competences and skills typically related to scientific literacy. But an emerging field of research on science teachers’ understanding and use of socioscientific issues, has documented that a range of challenges hinders the uptake of socioscientific issues. In this study, we investigated the interpretation and implementation of socioscientific issues among Danish biology teachers. We conducted five in-depth group interviews and validated the emergent themes from the teachers’ talk-in-interaction by distributing a questionnaire. Our findings suggest that the participating teachers generally harbour a content-centred interpretation of socioscientific issues which manifests itself in at least three separate ways. First, the teachers generally use socioscientific issues as a vehicle to teach factual biological content. Second, the teachers emphasised mastery of factual content in their assessment. Third, the teachers tended to reduce socioscientific issues to specific biological contents in a way may preclude students from engaging with the real socioscientific issue. Our findings are particularly significant for science educators, policy-makers and curriculum designers, as we argue that key aspects of this content-centred interpretation may be a coping strategy used to navigate a divided curriculum.  相似文献

Technology has become affordable and available for science teachers of all grade levels. This study presents the results of collecting attitudinal data from over 240 ninth grade physical science students prior to the integration of technology into their science curriculum. The data were evaluated utilizing a probabilistic model, which corrects for the nonlinearity of rating scale responses. Results indicate that surveyed students, on average, were supportive of the integration of a wide range of technology into their classroom. Although students were generally positive, they were statistically more supportive of activities that involved the sending of electronic messages to other students when a comparison was made to their attitudes toward the collecting of data with computer probes. The results suggest that physical science teachers may want to initiate the integration of technology into classes by first requiring students to use electronic mail to share data collected without the aid of a computer. This activity could, in turn, be followed by labs that require the collecting of data with computer probes and subsequent sharing of that data with other students through electronic mail.  相似文献

Abstract

Dialogic pedagogy is being promoted in science teacher education but the literature on dialogic pedagogy tends to focus on explicit voices, and so runs the risk of overlooking the important role that material objects often play in science education. In this paper we use the findings of a teacher survey and classroom case study to argue that there is a gap in the way that science teachers think about the role of materials and that this could be addressed by changes in the theory base of teacher training, augmenting the current constructivist and dialogic theory with the addition of new materialism in the form of Barad’s ‘Agential Realism’. Our findings suggests that science teachers do not regularly explicitly consider the relationship between the material resources they deploy and the dialogic learning taking place. We argue that science teacher training and professional development should pay more attention to the material-dialogic relationships in the learning that emerges in science classrooms.  相似文献

This is a study of an ongoing collaborative project in which science education faculty and upper elementary school teachers investigate the potential of a project-based, technologyrich, environmentally oriented approach to science education in an urban school serving a racially diverse population. Major conclusions based on the experience of participants in this study include: (1) teachers describe their instructional roles in terms highly consistent with student-centered, project-based, experiential learning; (2) teachers believe that what makes science real for students is the feeling that they are working on a truly current problem that is also being investigated by others outside their classroom. This is achieved by KidsNet, a microcomputer- and telecommunications-mediated curriculum, in a way that would not be possible without this technology; (3) teachers describe the actual and possible role of computer technology in terms which, while insightful and generally positive, are not clearly related to its flexible use in project-based learning; and (4) while teachers recognize meaningful connections between off-line science activities and the use of computer and telecommunications technologies, their students often do not.An earlier version of this paper was presented at the annual meeting of the American Educational Research Association, April 16, 1993, Atlanta, Georgia.This work was partially supported by a Higher Education Grant from the Dwight D. Eisenhower Mathematics and Science Education Improvement Program.  相似文献
