We present an inquiry‐based, aquatic science professional development (PD) for upper‐elementary, middle, and high school teachers and examine changes in student outcomes in light of participating teachers’ characteristics and the grade band of the students. Our study lends support to the assertion that inquiry‐ and content‐focused PD, paired with classroom implementation, can effectively improve student learning. Our findings indicate that students improved in their nature of science (NOS) and aquatic science content knowledge and that these changes depended in some ways on the participating teachers’ characteristics and adherence to the program. The students’ improvements were amplified when their teachers adhered more closely to the PD activities during their classroom implementation. The teachers’ previous science PD experience and pre‐PD understanding of inquiry‐based teaching also explained some of the variability in student growth. In both NOS and content, students of teachers with less prior science‐PD experience benefited more. Grade band also explained variation in student outcomes through interactions with teacher‐characteristic variables. In high school, students of teachers with lower pre‐PD inquiry knowledge appeared to learn more about NOS. Our results suggest that inquiry and content training through PD may minimize disparities in teaching due to inexperience and lack of expertise. Our study also demonstrates the value of PD that teaches a flexible approach to inquiry and focuses on underrepresented, interdisciplinary content areas, like aquatic science. © 2017 Wiley Periodicals, Inc.

Summary Science teachers naturally rely on their university science experiences as a foundation for teaching middle school science. This foundation consists of knowledge far too complex for the middle level students to comprehend. In order for middle school science teachers to utilize their university science training they must search for ways to adapt their college experiences into appropriate middle school learning experience. The criteria set forth above provide broad-based guidelines for translating university science laboratory experiences into middle school activities. These guidelines are used by preservice teachers in our project as they identify, test, and organize a resource file of hands-on inquiry activities for use in their first year classrooms. It is anticipated that this file will provide a basis for future curriculum development as the teacher becomes more comfortable and more experienced in teaching hands-on science. The presentation of these guidelines is not meant to preclude any other criteria or considerations which a teacher or science department deems important. This is merely one example of how teachers may proceed to utilize their advanced science training as a basis for teaching middle school science.  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 challenge of preparing students for the information age has prompted administrators to increase technology in the public schools. Yet despite the increased availability of technology in schools, few teachers are integrating technology for instructional purposes. Preservice teachers must be equipped with adequate content knowledge of technology to create an advantageous learning experience in science classrooms. To understand preservice teachers’ conceptions of technology integration, this research study explored 15 elementary science methods students’ definitions of technology and their attitudes toward incorporating technology into their teaching. The phenomenological study took place in a science methods course that was based on a constructivist approach to teaching and learning science through science activities and class discussions, with an emphasis on a teacher beliefs framework. Data were collected throughout the semester, including an open-ended pre/post-technology integration survey, lesson plans, and reflections on activities conducted throughout the course. Through a qualitative analysis, we identified improvements in students’ technology definitions, increased technology incorporation into science lesson plans, and favorable attitudes toward technology integration in science teaching after instruction. This research project demonstrates that positive changes in beliefs and behaviors relating to technology integration in science instruction among preservice teachers are possible through explicit instruction.  相似文献

Increasingly the curriculum area of science is being linked with technology. However, traditionally, technology education has been a major component of the ‘technical’ or ‘trades’ subjects in the secondary school. To what degree is this contemporary ‘science and technology’ an amalgamation of two previously separate secondary curriculum areas and what implications does this current development have for science/ technology teachers in training? This article is an account of one attempt to address these questions. It describes and evaluates an integrated undergraduate Bachelor of Education unit involving students from the specialist areas of science and design and technology.  相似文献

The present study deals with a school‐based professional development trajectory for secondary science teachers, aiming at scaffolding teachers in open‐inquiry teaching for the topic of water quality. Its design was based on the leading principle of ‘guiding by scaffolding’. Seven experienced teachers participated in institutional meetings and teaching at school. The research focused on designing scaffolding tools, addressing these tools in the meetings, and implementing them in the classroom. The main research data were obtained from meetings, classroom discussions, and observations. The results indicated that the professional development trajectory has promoted teachers’ learning of scaffolding students in open inquiry, especially the ability to know when and how to give students a well‐balanced combination of ‘structure’ for open‐inquiry learning and sufficient ‘space’ for that. The implications for science teacher education are discussed.  相似文献

The purpose of Science in Action (SIA) was to examine the relationship between implementing quality science, technology, engineering, and math (STEM) service-learning (SL) projects and the effect on students' academic engagement in middle school science, civic responsibility, and resilience to at-risk behaviors. The innovative project funded by the Corporation for National and Community Service (CNCS) included 6,000+ middle school at-risk students (eligible for at least 50% free or reduced-cost lunch), 126 science teachers who integrated STEM problem-based SL pedagogy into science instruction to teach students to solve real problems in schools and communities. The project involved 20 schools and communities with assistance from 120 community partners. Participants completed pre- and post-SL surveys on academic engagement, civic responsibility, and resilience; qualitative data were collected from journals, interviews, focus groups, observations, and field notes. Results highlight exemplary SL projects that demonstrated increased student academic engagement and achievement for students living in high poverty areas with potential at-risk behavior. Implications for future research and educational practices are discussed.  相似文献

3D printing technology is a powerful educational tool that can promote integrative STEM education by connecting engineering, technology, and applications of science concepts. Yet, research on the integration of 3D printing technology in formal educational contexts is extremely limited. This study engaged preservice elementary teachers (N?=?42) in a 3D Printing Science Project that modeled a science experiment in the elementary classroom on why things float or sink using 3D printed boats. The goal was to explore how collaborative 3D printing inquiry-based learning experiences affected preservice teachers’ science teaching self-efficacy beliefs, anxiety toward teaching science, interest in science, perceived competence in K-3 technology and engineering science standards, and science content knowledge. The 3D printing project intervention significantly decreased participants’ science teaching anxiety and improved their science teaching efficacy, science interest, and perceived competence in K-3 technological and engineering design science standards. Moreover, an analysis of students’ project reflections and boat designs provided an insight into their collaborative 3D modeling design experiences. The study makes a contribution to the scarce body of knowledge on how teacher preparation programs can utilize 3D printing technology as a means of preparing prospective teachers to implement the recently adopted engineering and technology standards in K-12 science education.  相似文献

Collaborations between the K-12 teachers and higher education or professional scientists have become a widespread approach to science education reform. Educational funding and efforts have been invested to establish these cross-institutional collaborations in many countries. Since 2006, Taiwan initiated the High Scope Program, a high school science curriculum reform to promote scientific innovation and inquiry through an integration of advanced science and technology in high school science curricula through partnership between high school teachers and higher education scientists and science educators. This study, as part of this governmental effort, a scientist–teacher collaborative model (STCM) was constructed by 8 scientists and 4 teachers to drive an 18-week high school science curriculum reform on environmental education in a public high school. Partnerships between scientists and teachers offer opportunities to strengthen the elements of effective science teaching identified by Shulman and ultimately affect students’ learning. Mixed methods research was used for this study. Qualitative methods of interviews were used to understand the impact on the teachers’ and scientists’ science teaching. A quasi-experimental design was used to understand the impact on students’ scientific competency and scientific interest. The findings in this study suggest that the use of the STCM had a medium effect on students’ scientific competency and a large effect on students’ scientific individual and situational interests. In the interviews, the teachers indicated how the STCM allowed them to improve their content knowledge and pedagogical content knowledge (PCK), and the scientists indicated an increased knowledge of learners, knowledge of curriculum, and PCK.  相似文献

A disconnect exists between students’ comfort with using technology for learning and teachers’ comfort in using technology for teaching. Students report the desire for more engaging technology-based assignments. Teachers cite multiple reasons for their hesitancy to use technology in their teaching. The current study investigates whether this disconnect has implications for students’ evaluations of their teachers. Using data from 101 high school students, researchers found that students’ perceptions of their teachers’ comfort with technology impacts their evaluations only when student affect for technology is high. Implications for how this might impact teacher evaluations and directions for future research are discussed.  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

This study investigated the degree that Science and Engineering Practices (SEPs) criteria from the Next Generation Science Standards (NGSS) were included in self-reported teaching practices of twelfth-grade science teachers in Jordan. This study sampled (n?=?315) science teachers recruited from eight different public school directorates. The sample was surveyed using an instrument adapted from Kawasaki (2015). Results found that Jordanian science teachers incorporate (SEPs) in their classroom teaching at only a moderate level. SEPs applied most frequently included ‘using the diagram, table or graphic through instructions to clarify the subject of a new science,’ and to ‘discuss with the students how to interpret the quantitative data from the experiment or investigation’. The practice with the lowest frequency was ‘teach a lesson on interpreting statistics or quantitative data,’ which was moderately applied. No statistically significant differences at (α?=?0.05) were found among these Jordanian science teachers’ self-estimations of (SEP) application into their own teaching according to the study’s demographic variables (specialisation, educational qualification, teaching experience). However, a statistically significant difference at (α?=?0.05) was found among Jordanian high school science teachers’ practice means based on gender, with female teachers using SEPs at a higher rate than male teachers.  相似文献

There is a current national emphasis on science, technology, engineering, and mathematics (STEM). Additionally, many states are transitioning to the Next Generation Science Standards (NGSS), which encourage teachers to incorporate engineering in science classrooms as well as have their students learn science by doing science. Methods courses are also shifting to adequately prepare preservice science teachers in these areas. This study examines preservice science teachers’ pre- and post-ideal inquiry-based lesson plan scenarios before and after intervention in their Secondary Science Methods I and II courses. These preservice science teachers participated in a variety of opportunities to practice authentic science inquiry (ASI) pedagogical techniques as well as integrated STEM topics, with a particular emphasis on computer programming throughout their 80 h of Methods instruction. ASI is a type of inquiry where students learn science by conducting science research in a grade-appropriate manner. Thirty-eight preservice teachers’ scenarios were analyzed using a rubric from Spuck (2014) to determine the degree to which the ten components of ASI were included in scenarios pre- to post-instruction. Trends in ASI component inclusion are discussed. These findings indicate that preservice science teachers are proficient at writing inquiry-based lessons where they planned opportunities for their future students to collaborate, use scientific instrumentation, and collect and analyze data, but need additional support with developing student activities where students create testable questions, revise their question and methods, participate in peer review, and disseminate their results to their peers or the larger scientific community. Overall, the results suggest Methods instruction should reinforce preservice teachers’ focus on planning lessons which include opportunities for all ASI components. Interventions in the aforementioned areas of weak inclusion may be beneficial to preservice teachers.  相似文献

ABSTRACT

This project incorporated live broadcasts of teaching from small, multi‐graded, rural schools into university lecture halls where pre‐service teacher education students in the last semester of their programmes were able to observe ‘best practice’ in a learning context that they would eventually be responsible for during their final practicum session. Interactive observation sessions were immediately followed with opportunities for students to discuss various aspects of planning, classroom organisation and teaching strategies appropriate to multi‐graded contexts with the remote classroom teacher. These ‘reverse distance education’ sessions followed an intensive lecture and tutorial series centring upon topics relevant to teaching in small rural communities. Tutorial activities placed student teachers in small rural school scenarios containing everyday ‘problems’ requiring diagnosis and the generation and analysis of solutions. At the conclusion of scenario discussions, students had networked, collaborated with colleagues and applied current research findings in generating viable solutions and considered school community reactions to these proposed solutions.

The incorporation of interactive video technology with these problem situations consolidated the concept and skill development of student teachers and increased both their real time involvement in their chosen professions, and their access to best practice. This dual focus upon a problem solving approach to teaching immersed the student teacher in situations derived from real school environments, and so encouraged a collegial and open approach to teaching. Extensive evaluations revealed that pre‐service teachers were more thoroughly prepared for rural teaching experiences, displayed competence in effective multigrade teaching skills, and exhibited control during involvement  相似文献

This study was aimed at detecting the most frequently-used teaching and assessment activities in secondary school science classes, identifying links between these variables, and revealing possible challenges in these processes. To this end, data were gathered from 155 secondary school science teachers in 56 Israeli public schools and 380 grade eight and nine students from 22 of these using the What Is Happening In this Class? Teachers were also asked to indicate their perceptions of the extent to which they used formative assessment tasks provided by the curriculum and to specify, in their own words, the reason for insufficient usage of these tasks. Task orientation was highly used in science classes, whereas investigation was the least employed activity, according to both teachers’ and students’ perceptions. The most-frequently used tasks to evaluate students were final tests and quizzes. Path model analysis revealed that teachers who tended to use teacher-based approaches also employed traditional assessment tools, whereas teachers who allowed students to cooperate rather than compete with one another tended to use formative assessment tools. Implications limitations, and directions for future research are discussed.  相似文献

The science curriculum is a focus of repeated reform in many countries. However, the enactment of such reforms within schools rarely reflects the intended outcomes of curriculum designers. This review considers what we know about the experiences and reflections of teachers in the enactment of externally driven school science curriculum reform. ‘Externally driven’ signals a focus on studies of teachers who did not make a proactive choice to adopt a particular curriculum reform initiative. This is a very common experience for teachers in many school systems, and one likely to highlight issues of professionalism and authority that are central to the work of teachers. The review analyses 34 relevant studies. These include studies of teachers’ experiences of national curriculum reform, and also studies focusing on more regional or local curriculum reform activities. The studies examine individual teachers’ beliefs, practices and reflections associated with curriculum reform, the response of teacher communities to reform (e.g. within school departments), and teachers’ (and other stakeholders’) experiences across school systems. A wide range of factors influencing teachers’ responses are identified. These are characterised in terms of personal, internal and external contexts of teachers’ work. The review also highlights issues of authority, professionalism and the process of meaning-making in response to external curriculum reform. The discussion section identifies important areas for future research and gives recommendations for the design of curriculum policies that recognise and support the professionalism of science teachers.  相似文献

The underrepresentation of women in science, technology, engineering, and mathematics (STEM) fields is problematic given the economic and social inequities it fosters and the rising global importance of STEM occupations. This paper examines the role of the demographic composition of high school faculty—specifically the proportion of female high school math and science teachers—on college students’ decisions to declare and/or major in STEM fields. We analyze longitudinal data from students who spent their academic careers in North Carolina public secondary schools and attended North Carolina public universities. Our results suggest that although the proportion of female math and science teachers at a school has no impact on male students, it has a powerful effect on female students’ likelihood of declaring and graduating with a STEM degree, and effects are largest for female students with the highest math skills. The estimates are robust to the inclusion of controls for students’ initial ability.  相似文献
