The effect of a problem solving in-service program on the classroom behaviors and attitudes of middle school science teachers

This study examines the effect of an in-service education program emphasizing problem solving on teacher attitudes toward teaching science and on teaching behaviors. Twenty-two middle school science teachers participated in the program and another 22 served as the control group. The two groups were similar in terms of gender, teaching status, educational background, and professional activity during the treatment period. Before and after the eight-month project, subjects completed attitude surveys and recorded videotapes of themselves teaching science lessons. No difference was noted between the groups on the attitude measure. The videotapes were analyzed using a coding scheme developed for use in this study. A multivariate analysis of variance performed on the observational data showed a significant difference between the groups on the postworkshop measure. The experimental-group teachers shifted to more student-centered classrooms, with less lecture and procedural talk. This study provides evidence that an extended in-service education program can affect the teaching behaviors of science teachers in the middle grades.     

Examining the effect of teachers' adaptations of a middle school science inquiry‐oriented curriculum unit on student learning

Reform based curriculum offer a promising avenue to support greater student achievement in science. Yet teachers frequently adapt innovative curriculum when they use them in their own classrooms. In this study, we examine how 19 teachers adapted an inquiry‐oriented middle school science curriculum. Specifically, we investigate how teachers' curricular adaptations (amount of time, level of completion, and activity structures), teacher self‐efficacy (teacher comfort and student understanding), and teacher experience enacting the unit influenced student learning. Data sources included curriculum surveys, videotape observations of focal teachers, and pre‐ and post‐tests from 1,234 students. Our analyses using hierarchical linear modeling found that 38% of the variance in student gain scores occurred between teachers. Two variables significantly predicted student learning: teacher experience and activity structure. Teachers who had previously taught the inquiry‐oriented curriculum had greater student gains. For activity structure, students who completed investigations themselves had greater learning gains compared to students in classrooms who observed their teacher completing the investigations as demonstrations. These findings suggest that it can take time for teachers to effectively use innovative science curriculum. Furthermore, this study provides evidence for the importance of having students actively engaging in inquiry investigations to develop understandings of key science concepts. © 2010 Wiley Periodicals, Inc., J Res Sci Teach 48: 149–169, 2011

Using action research as a methodological tool: understanding teachers' understanding of science

A series of questions and answers between Jennifer Nias in her role as supervisor and Steve Waters-Adams as student explores the rationale for the inclusion of action research as a methodological tool within a wider PhD study. The study explored the effect of teachers' understanding of the nature of science on their teaching. In discussing the complexities of the research, Steve Waters-Adams suggests that action research provided a powerful means of gaining access to important tacit and dialectical aspects of teachers' practice. The discussion considers the process of action research, particularly with regard to the extent that its form and purpose may be defined, the importance of collaboration and the centrality of personal commitment. Steve Waters-Adams concludes that there is scope for subject-oriented research in education to make more use of action research as a methodological tool, given that the process engages with, and exposes for scrutiny, practitioners' values, aims and motives.     

Evaluating prospective elementary teachers' understanding of science and mathematics in a model preservice program

Two cohorts of students preparing to become elementary teachers participated in a model program in science and mathematics. These students were compared to other students taking similar courses on their conceptual understandings of science and mathematics, their investigative proficiencies, and their beliefs about effective methods of teaching these subjects. Instruments included newly developed tests of understanding, existing standardized achievement tests, and instruments devised for the evaluation to elicit conceptions of appropriate ways to teach science and mathematics to elementary children. Results from individual courses indicated that students participating in the model program developed more thorough understandings and more reform-minded beliefs related to teaching science and mathematics. Issues associated with the assessment and evaluation of innovative programs in science and mathematics are discussed, and recommendations for teacher preparation are offered.     

The impact of a professional development model on middle school science teachers' efficacy and implementation of inquiry

This study investigated a professional development model designed to improve teachers' inquiry teaching efficacy as well as the quality of their inquiry instruction through engaging teachers in practice-teaching and reflection sessions. The programme began with a two-week summer Institute focused on both inquiry pedagogy and science content and continued with academic year support for participants' inquiry implementation. An inquiry teaching efficacy instrument was administered 3 times to 25 teacher participants to gauge changes in their personal self-efficacy and outcome expectancy across 5 essential features of classroom inquiry. To examine actual practices, pre/post classroom observations of the teachers' inquiry enactments were evaluated using a quality of inquiry observation protocol. Following the summer Institute, teachers had statistically significant increases in their self-efficacy for teaching inquiry in four of the five essential features and increases in one of the five essential features for outcome expectancy. Teachers' quality of inquiry teaching also increased after the professional development programme. We discuss implications of this PD model for moving teachers towards implementation of new instructional techniques as well as the influence of a supportive school community on teachers’ efficacy with inquiry instruction.     

Student use of animated pedagogical agents in a middle school science inquiry program

Animated pedagogical agents (APAs) have the potential to provide one‐on‐one, just‐in‐time instruction, guidance or mentoring in classrooms where such individualized human interactions may be infeasible. Much current APA research focuses on a wide range of design variables tested with small samples or in laboratory settings, while overlooking important practical issues relating to large‐scale, school‐based implementations. The present study provides an early step in addressing this gap by investigating the patterns, affordances and challenges of sustained classroom use of APAs. During a 15‐class‐period science curriculum, middle school students in the treatment groups (n_{Dr C‐1} = 191; n_{Dr C‐2} = 181) had uninterrupted classroom access to one of the two APAs, while control group students (n = 149) completed the same curriculum without APA access. Usage patterns indicate that students accessed the APAs on a fluctuating, “as needed,” basis corresponding to the introductory, information‐gathering, and synthesis and reporting segments of the curriculum. Survey results revealed no statistically significant difference in student feelings toward the APAs between the two treatments. While treatment students reported that the APAs were unique, reliable, timely resources, interviews indicate little difference between their experiences with the curriculum and those of the control group. Results presented here provide guidance for researchers and practitioners.     

Effects of a professional development program on science teacher knowledge and practice,and student understanding of interdisciplinary science concepts

Situated in the context of an in-service professional development (PD) program focused on Interdisciplinary Science Inquiry, this quantitative study tests the validity of and further explores the theoretical model adapted from Desimone's (2009), Educational Researcher, 38, 181–199 conceptual framework on effectiveness of PD. The participants include 204 teachers and 5,581 students within 12 local public schools from 2012 to 2016. The multilevel models indicate that PD participation, school-, and teacher-level factors influence teacher pedagogical content knowledge and inquiry instruction in different ways. Furthermore, the inquiry instruction significantly relates student understanding of interdisciplinary science concepts (ISCs) through a few mediators. Therefore, this study reinforces calls to provide teachers with high quality PD and contributes to current knowledge base of the mechanisms of how inquiry instruction influences students' understanding of ISCs.

The role of treatment acceptability,effectiveness, and understanding in treatment fidelity: Predicting implementation variation in a middle school science program

Evaluating a school-based program is a particular challenge when teachers implementing the program. Variations in implementation can be difficult to measure and predict. We developed measures to explore variation in treatment implementation and serve as predictors of variation in a school-based science education program. Based on previous work, we focused on assessing treatment acceptability, effectiveness, and understanding among teachers as critical determinants of variations in program implementation using self-reported and objective measures of implementation. All three constructs were associated with implementation of the program. Our measures of these constructs show promise for use in formative and summative evaluations. Our stratification of program elements with implementation predictors can provide a template for future exploration of treatment fidelity.     

A case study of one school system's adoption and implementation of an elementary science program

In this investigation we employed a case study approach with qualitative and quantitative data sources to examine and discover the characteristics of the processes used by a midwestern U.S. school system to adopt and implement a new K–6 science curriculum. Analysis of data yielded several results. Elementary teachers received what they requested, a hands‐on science program with texts and kits. Teachers as a group remained in the early stages of the Concerns‐Based Adoption Model profile of concerns. Many K–6 teachers remained uncomfortable with teaching science. Teachers' attitudes regarding the new program were positive, and they taught more science. Teachers struggled with science‐as‐inquiry, with a science program they believe contained too many concepts and too much vocabulary, and with their beliefs that students learned more and loved the new hands‐on program. Traditional science teaching remained the norm. Administrative support was positive but insufficient to facilitate full implementation of the new program and more substantial change in teaching. Standardized science achievement test scores did not show an observable pattern of growth. It is concluded that a systematic, ongoing program of professional development is necessary to address teachers' concerns and help the district realize its goal of standards‐based K–6 science instruction. © 2004 Wiley Periodicals, Inc.

A case study of high school teachers' decision making models for planning and teaching science

The focus of this study was to investigate the manner and the degree to which science teachers consider the nature of the subject matter in their decision making addressing the planning and the delivery of instructional tasks. An assumption of the study is that considerations for the nature of the subject matter should be a factor in a teacher's decision making about what to teach and how to teach. Relevant research literature reviewed includes (1) human decision making and the development of cognitive models of reality, (2) modern philosophies of science, and (3) philosophy of science and science education. Methods of data collection and of data analysis followed Spradley's Developmental Research Sequence guidelines for conducting ethnographic research. Validity of research findings was established from the triangulation of observations, interviews, and documents and surveys. The goal of the research was the development of grounded hypotheses about science TEACHERS' pedagogical decision making. Based on the results of this study it is hypothesized that science TEACHERS' decision-making models of reality for the selection, implementation, and development of instructional tasks are dominated by considerations for (a) student development, (b) curriculum guide objectives, and (c) pressures of accountability. Little, if any, consideration is given to the nature of the subject matter by the science teachers in decision making. Implications exist for the disenfranchisement of teachers from the task of making decisions concerning what to teach.     

A study of learning and motivation in a new media enriched environment for middle school science

This study examines middle school students’ learning and motivation as they engaged in a new media enriched problem-based learning (PBL) environment for middle school science. Using a mixed-method design with both quantitative and qualitative data, we investigated the effect of a new media environment on sixth graders’ science learning, their motivation, and the relationship between students’ motivation and their science learning. The analysis of the results showed that: Students significantly increased their science knowledge from pretest to posttest after using the PBL program, they were motivated and enjoyed the experience, and a significant positive relationship was found between students’ motivation scores and their science knowledge posttest scores. Findings were discussed within the research framework.     

A theoretical understanding of the literature on student voice in the science classroom

Background: Incorporating student voice into the science classroom has the potential to positively impact science teaching and learning. However, students are rarely consulted on school and classroom matters. This literature review examines the effects of including student voice in the science classroom.

Purpose: The purpose of this literature review was to explore the research on student voice in the science classroom. This review includes research from a variety of science education sources and was gathered and analyzed using a systematic literature review process.

Design and methods: I examined articles from a variety of educational journals. I used three key terms as my primary search terms: student voice, student perceptions, and student perspectives. The primary search terms were used in conjunction with qualifiers that included science education, science curriculum, student emergent curriculum, student centered curriculum, and science. In order to be included in the literature review, articles needed to be published in peer-reviewed, academic journals, contain clearly defined methods (including quantitative, qualitative, or mixed methods), include research conducted in K through 12 classrooms, include the term ‘student voice’, and focus specifically on science. I included articles from a variety of science classrooms including general middle school science, science-specific after-school programs, secondary science classrooms in a variety of countries, and physics, biology, and aerospace classrooms. No restrictions were placed on the country in which the research was conducted or on the date of the research.

Conclusions: The results of the literature review process uncovered several themes within the literature on student voice. Student voice research is situated within two main theoretical perspectives, critical theory and social constructivism, which I used as the main themes to structure my findings. I also identified subcategories under each main theme to further structure the results. Under critical theory, I identified three subcategories: determining classroom topics, developing science agency, and forming identities. Under social constructivism, I discovered four subcategories: forming identities, incorporating prior knowledge and experience, communicating interest in topics and classroom activities, and improving student–teacher relationship. The research supports that allowing students a voice in the classroom can lead them to feel empowered, able to construct their own meaning and value in science, demonstrate increased engagement and achievement, and become more motivated. I conclude students should be allowed a voice in the science classroom and to continue to ignore these voices would be a disservice to students and educators alike.
