Teaching nature of science through inquiry: Results of a 3‐year professional development program

This study assessed the influence of a 3‐year professional development program on elementary teachers' views of nature of science (NOS), instructional practice to promote students' appropriate NOS views, and the influence of participants' instruction on elementary student NOS views. Using the VNOS‐B and associated interviews the researchers tracked the changes in NOS views of teacher participants throughout the professional development program. The teachers participated in explicit–reflective activities, embedded in a program that emphasized scientific inquiry and inquiry‐based instruction, to help them improve their own elementary students' views of NOS. Elementary students were interviewed using the VNOS‐D to track changes in their NOS views, using classroom observations to note teacher influences on student ideas. Analysis of the VNOS‐B and VNOS‐D showed that teachers and most grades of elementary students showed positive changes in their views of NOS. The teachers also improved in their science pedagogy, as evidenced by analysis of their teaching. Implications for teacher professional development programs are made. © 2006 Wiley Periodicals, Inc.

Investigating the role of computer‐supported annotation in problem‐solving‐based teaching: An empirical study of a Scratch programming pedagogy

For more than 2 years, Scratch programming has been taught in Taiwanese elementary schools. However, past studies have shown that it is difficult to find appropriate learning methods or tools to boost students’ Scratch programming performance. This inability to readily identify tutoring tools has become one of the primary challenges addressed in Scratch programming studies. To cope with this problem, we propose an innovative approach, which combines an Annotation‐based Scratch Programming (ASP) tool with the problem‐solving‐based teaching approach in Scratch programming pedagogy. The ASP tool was developed to enable students to create, review and share Scratch programming and homework annotations. In a quasi‐experimental study, we have evaluated Scratch programming pedagogy at a North Taiwanese elementary school to investigate the effects of instructional‐tools‐supported programming instructional modes on Scratch programming performance. The experimental results show that students who received ASP tool support in conjunction with a problem‐solving‐based teaching approach performed significantly better than the other groups. Based on our findings, the innovative approach was believed to play an important role in improving the learning patterns of younger pupils. Therefore, we suggest that teachers consider incorporating the innovative method into their teaching environments in order to boost students’ learning achievements in the area of Scratch programming and the subsequent learning process.     

A Problem‐based Learning Model for Teaching the Instructional Design Business Acquisition Process

There is a growing emphasis on utilizing a problem‐based learning [PBL] pedagogy to help instructional design students gain an understanding of the complex forces operating within an actual design environment. However, little literature exists to suggest that PBL is being used to teach the process by which instructional design firms and practitioners secure work—the Instructional Design Business Acquisition Process (IDBAP). This study outlines a conceptual framework for using an adapted problem‐based learning model for teaching the IDBAP, which consists of writing a response to a request for proposal (RFP), developing a working prototype, and orally presenting the solution. This study also examines the impact of a PBL pedagogy on students' perception of their confidence in solving instructional design problems. The results of this empirical research indicate that students who participate in a problem‐based learning pedagogy gain confidence in their abilities to solve instructional design problems, view themselves in emotional control when solving an instructional design problem, and are more inclined to approach similar problems in the future.

A Multi-Year Study of the Impact of the Rice Model Teacher Professional Development on Elementary Science Teachers

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.     

Can Good Concept Mappers be Good Problem Solvers in Science?

Problem solving is an enduring issue in science education, ostensibly because science itself is basically concerned with problem solving—exploring the universe and seeking answers to intriguing phenomena in nature. Remarkable strides have been made in psychology about recording the minutiae of problem solving as a cognitive process. Concept mapping, a metalearning tool, is appearing on the scene as a potential pathway for promoting the acquisition of problem‐solving skills. Drawing 40 subjects from a pool of students who experienced cooperative and individualistic concept‐mapping experiences for six months and adjudged to be good concept mappers, this study found the concept‐, mapping group to be significantly more successful in solving three biological problems than 20 subjects who served as control. Written and think‐aloud procedures and interviews were conducted as part of the administration of the Biology Problem Solving Test. No statistically significant difference was found between students who mapped concepts cooperatively and those who mapped individually. There were mixed results for gender. The implications of the findings for further research and for improving problem‐solving abilities of students are drawn.     

Teachers' learning while constructing technology‐based instructional resources

Grounded in a constructionist paradigm, this study examined elementary school teachers' learning while creating technology‐rich instructional materials. Sixteen teachers at an elementary school were interviewed about their experience. Using the components of Technological Pedagogical and Content Knowledge as an analytical framework, inductive qualitative analysis indicated that these professional learning activities led to teachers' growth primarily in technological knowledge, technological pedagogical knowledge and content knowledge. These findings as well as implications for designing professional learning activities for teachers are also shared.     

University Science Teachers as Researchers: Blurring the Scholarship Boundaries

In this paper I examine the phenomenon of university teachers as researchers in their own classrooms. I use examples of three research teams in which we studied: (1) student response to a science and society course; (2) teacher and student perceptions of inquiry in a physics course; and (3) teaching and learning about the nature of science in an elementary science pedagogy course. In addition to describing each study, I compare their purposes, researcher roles, and actions taken. I use these comparisons to address the ideological clashes and dilemmas of ownership, action, and quality that arise in this kind of research. Finally, I comment upon the significance of university teachers as researchers for themselves, their institutions, and the research community.     

Social Activism in Elementary Science Education: A science,technology, and society approach to teach global warming

As part of a large‐scale instructional intervention research, this study examined elementary students’ science knowledge and awareness of social activism with regard to an increased greenhouse effect and global warming. The study involved fifth‐grade students from five elementary schools of varying demographic makeup in a large urban school district in the United States. The study was based on the analysis of students’ responses to a writing prompt addressing an increased greenhouse effect and global warming at the beginning of and at the completion of instruction over the school year. The results indicate that students with adequate science knowledge tended to express activism more frequently, and that their expression of activism increased as they gained better science knowledge after the instruction. The results highlight the importance of effective instruction of this contemporary and controversial issue with K‐12 students, so that they come to be aware of this societal problem, take action in solving the problem, and become socially responsible youth and adults.     

Exploring the role of TPACK and teacher self-efficacy: an ethnographic case study of three iPad language arts classes

This ethnographic research study investigated three elementary teachers’ perceived self-efficacy beliefs and their attitudes toward mobile technology-enhanced instruction. Using technological pedagogical content knowledge (TPACK) as a guiding theory, the authors sought to determine whether and how the three knowledge components that form the foundation of the TPACK framework– technological, pedagogical or content knowledge – have similar levels of influence on teachers’ language arts teaching practices. They also examined how each teacher incorporated iPad technologically enhanced pedagogical practices and made connections to their beliefs about the role of technology and education. Data collection consisted of classroom observation field notes, teacher interviews and teacher blogs. Findings reveal that the teachers’ attitudes toward the integration of iPad technology formed a basis for how they approached their pedagogy. Compared to their technological and content knowledge, teachers’ pedagogical knowledge and years of teaching experience strongly influenced their decisions regarding mobile technology integration. By the end of the study, all teachers identified stronger connections and awareness in relation to the components of TPACK. The implications of these findings will provide insight relevant to the development of professional development opportunities for teachers regarding TPACK that could ultimately lead to more successful technology integration by teachers.     

Designed and Spontaneous Gestures in Elementary Astronomy Education

We make a case for using gestures and actions to understand and convey spatial and dynamic properties of systems. Problems in learning elementary astronomy are analysed in the context of demands of spatial thinking, in a system which is not amenable to direct perception, namely, the sun–earth–moon (SEM) system. We describe a pedagogy which uses gestures (most often in combination with concrete models and diagrams) to facilitate the visualisation and simulation required in elementary astronomy. These gestures are presented in terms of their purpose in pedagogy: to internalise a natural phenomenon, or an astronomical model, or general properties of space. In terms of design these pedagogical gestures mediate between concrete models of the SEM system and related spatial configurations on the one hand, and their corresponding abstract diagrammatic representations on the other: called here the model–gesture–diagram pedagogical link. Next we present some video data on students’ gestures observed during collaborative problem‐solving which took place in the course of our pedagogic intervention. Implications of these results are drawn for embodiment and multimodality of thought.     

Mathematical Problem Solving with Technology: the Techno-Mathematical Fluency of a Student-with-GeoGebra

This study offers a view on students’ technology-based problem solving activity through the lens of a theoretical model which accounts for the relationship between mathematical and technological knowledge in successful problem solving. This study takes a qualitative approach building on the work of a 13-year-old girl as an exemplary case of the nature of young students’ spontaneous mathematical problem solving with technology. The empirical data comprise digital records of her approaches to two problems from a web-based mathematical competition where she resorted to GeoGebra and an interview where she explains and describes her usual problem solving activity with this tool. Based on a proposed model for describing the processes of mathematical problem solving with technologies (MPST), the main results show that this student’s solving and expressing the solution are held from the early and continuing interplay between mathematical skills and the perception of the affordances of the tool. The analytical model offers a clear picture of the type of actions that lead to the solution of each problem, revealing the student’s ability to deal with mathematics and technology in problem solving. By acknowledging this as a case of a human-with-media in solving mathematical problems, the students’ efficient way of merging technological and mathematical knowledge is portrayed in terms of her techno-mathematical fluency.     

Case‐based pedagogy as a context for collaborative inquiry in the Philippines

The purpose of this study was to investigate the potential for using case‐based pedagogy as a context for collaborative inquiry into the teaching and learning of elementary science. The context for this study was the elementary science teacher preparation program at West Visayas State University on the the island of Panay in Iloilo City, the Philippines. In this context, triple linguistic conventions involving the interactions of the local Ilonggo dialect, the national language of Philipino (predominantly Tagalog) and English create unique challenges for science teachers. Participants in the study included six elementary student teachers, their respective critic teachers and a research team composed of four Filipino and two U.S. science teacher educators. Two teacher‐generated case narratives serve as the centerpiece for deliberation, around which we highlight key tensions that reflect both the struggles and positive aspects of teacher learning that took place. Theoretical perspectives drawn from assumptions underlying the use of case‐based pedagogy and scholarship surrounding the community metaphor as a referent for science education curriculum inquiry influenced our understanding of tensions at the intersection of re‐presentation of science, authority of knowledge, and professional practice, at the intersection of not shared language, explicit moral codes, and indigenization, and at the intersection of identity and dilemmas in science teaching. Implications of this study are discussed with respect to the building of science teacher learning communities in both local and global contexts of reform. © 2001 John Wiley & Sons, Inc.

Workplace performance–PLUS: Empowerment and voice through professional development and democratic processes in health care training

Based on the theory of transformative learning (Mezirow, 1980) and critical pedagogy (Freire, 1980), mixed‐methods research (Tashakkori & Teddlie, 1998) of a hospital workers' union and training organization addressed the impact of a custom‐designed, group‐focused, results‐driven professional development model with 130 participants. Employees across many job titles participated. Findings reveal substantial content learning, along with the development of empowerment and voice. The purpose of the research was to determine the ways and the extent that worker voice, satisfaction, attitude, communication, and problem solving improved as workers and managers put into practice knowledge and skills learned through the training (Winchester, 2003). The scope of results includes efficiency and skill improvements and qualitative changes intersecting professional and personal realms.     

In search of well‐started beginning science teachers: Insights from two first‐year elementary teachers

The purpose of this qualitative case study was to explore what aspects of two first‐year elementary teachers' practices were most consistent with an inquiry‐based approach, what PCK served as a mechanism for facilitating these practices, and what experiences have mediated the nature and development of these teachers' PCK. For each of the participants data included audio‐recorded interviews, video‐recorded classroom observations, lesson plans, and samples of student work. Data analysis illustrated that both participants engaged their students in question‐driven investigations, the use of observational data, making connections between evidence and claims, and communicating those claims to others. Moreover, there was clear evidence in the findings of the study that a considerable degree of coherence existed between the two participants' knowledge on one hand and their instructional practices on the other hand. The participants perceived specific learning experiences during their programs as being critical to their development. The contribution of this study lies in the fact that it provides examples of well‐started beginning elementary teachers implementing inquiry‐based science in 2nd and 5th grade classrooms. Implications of the study include the need for the design of university‐based courses and interventions by which teacher preparation and professional development programs support teachers in developing PCK for scientific inquiry and enacting instructional practices that are congruent with reform initiatives. © 2010 Wiley Periodicals, Inc.

Impact of professional development programme on teachers’ competencies in assessment

ABSTRACT

In the past few decades, increasing demands have been placed on developing students’ autonomy and critical thinking skills. To enhance students’ agency in learning, teachers have been encouraged to adopt alternative pedagogical practices. The revamp of pedagogy needs to be reflected in assessment as it is an integral part of instruction. Practising teachers, however, lack assessment knowledge due to inadequate training during the pre-service preparation programmes. The enhancement of assessment knowledge is being urgently called for, which demands the professional development of teachers. This study seeks to investigate the impact of a professional development programme organized by a university in Hong Kong on the development of assessment knowledge of four teachers in two elementary schools. Findings indicate that the acquisition of assessment knowledge is a long-term achievement, which requires ongoing professional development efforts.

Effects of Integrating Hypermedia into Elementary Science Professional Development on Science Content Knowledge

Past research has indicated that a number of problems in the teaching of science in elementary classrooms are rooted in the preparation of inservice teachers. One continuing concern is elementary teachers' lack of science content knowledge. As indicated by numerous research studies reporting positive results, one method of addressing these problems is through inservice teacher professional development workshops. While improved content knowledge has been reported as a positive result of professional development workshops, elementary science workshops have not resulted in the same success levels as other subject areas. One method of addressing some of the deficiencies in elementary science professional development workshops is with the integration of hypermedia into the professional development environment. This study examined whether the integration of hypermedia into elementary science professional development workshops resulted in greater increases in the science content knowledge of elementary teachers of science than traditional methods of elementary science professional development workshops. Workshops that integrated hypermedia into the professional development environment resulted in a significant increase in inservice elementary teachers' science content knowledge, when compared to the control group. However, when compared to the experimental group that participated in workshops without hypermedia, however, there was no significant difference in increases of science content knowledge. Implications of these outcomes are discussed.     

Building a whole school approach and teacher efficacy with English language learners

Current professional development initiatives show a preference for whole school approaches. However, pedagogy related to English language learners (ELLs) is often not widely dispersed in New Zealand primary schools, impacting on teacher efficacy with these learners. This paper discusses findings from a qualitative study which aimed to identify influences shaping the dispersal of ELL-related pedagogy in two schools in contrasting socio-economic areas. Data from semi-structured individual interviews with teachers at different class levels revealed unique patterns for the dispersal of ELL-related pedagogy in each school. Teacher data indicated that these patterns were influenced by the performance of ELLs in national standards testing, as well as the special characteristics of ELLs in each setting and the distinctive nature of each context. The dispersal of ELL pedagogy in each school impacted differentially on opportunities to build a sense of collective teaching efficacy with ELLs in that setting, but also raised questions about whether one size should be expected to fit all.
