This study aimed to develop and evaluate a web-based TPACK scaffolding for online learning to enhance the TPACK skills of preservice chemistry teachers. The preliminary study identified the lack of a clear perception of TPACK among preservice chemistry teachers. Therefore, we developed a web-based TPACK scaffolding tool consisting of five menus:…

This study investigated the extent to which a state-funded teacher professional development program designed to improve K-2 science education led to changes that persisted beyond the funding period. The study used a longitudinal, mixed-methods approach and examined persistence of changes in teachers' content knowledge, self-efficacy, instructional…

Formative assessment has been demonstrated to result in increased student achievement across a variety of educational contexts. When using formative assessment strategies, teachers engage students in instructional tasks that allow the teacher to uncover levels of student understanding so that the teacher may change instruction accordingly. Tools…

This was a Research and Developmental study designed to develop and validate projects for Junior Secondary School Basic Science instruction and evaluation. The projects were developed using the project blueprint and sent for validation by experts in science education and measurement and evaluation; using a project validation scale. They were to…

Within the field of science education, there remains little agreement as to the definition and characteristics of classroom inquiry. The emerging emphasis on scientific practices in science education reform discourse is underpinned by a need to better articulate the constituent elements of inquiry-based science. While a small number of…

This paper presents the findings of an investigation carried out in Sri Lanka to explore how mobile phones can support science teachers' pedagogical practices throughout the teaching cycle of planning, teaching and evaluation. Data were collected using observation supported by audio and video recordings from both continuing professional…

A Victorian government initiative called "The Primary Science Specialists Professional Learning Program" is designed to tackle students' falling interest in science by investing in the building of teacher capacity. The aims of the initiative are: to improve the science knowledge base of all teachers and therefore increase teachers'…

Summer Enrichment Workshop (SEW) is a 3-week enrichment program held at The University of Alabama (UA) Tuscaloosa, Alabama, for students identified as gifted and talented. The faculty of the College of Education, Program of Gifted and Talented (GT), formed a partnership with a College of Engineering faculty member who mentored the graduate student…

In New Zealand and internationally claims are being made about the potential for information and communication technologies (ICTs) to transform teaching and learning. However, the theoretical underpinnings explaining the complex interplay between the content, pedagogy and technology a teacher needs to consider must be expanded. This article…

The study reported in this article draws upon data collected for the programme "Increasing the Efficiency of Mathematics and Science instruction" (SINUS-Transfer), a professional development project in Germany. This programme's approach requires teachers to improve their teaching in a cooperative manner and with regard to pedagogical…

Epistemic criteria are the standards used to evaluate scientific products (e.g., models, evidence, arguments). In this study, we analyzed epistemic criteria for good models generated by 324 middle-school students. After evaluating a range of scientific models, but before extensive instruction or experience with model-based reasoning practices,…

Although many states in the United States are adopting policies that require all students to complete college-preparatory science classes to graduate from high school, such policies have not always led to improved student outcomes. There is much speculation about the cause of the dismal results, but there is scant research on the processes by…

The purpose of this pragmatic action research study was to explore our re-conceptualization efforts in preparing pre-service teachers to guide the inquiry process with formative assessment and subsequently use the understandings to improve our teacher preparation program. The process was guided by two questions: to what extent did course…

California's public schools have struggled since the passage of Proposition 13 in 1978, and today face enormous challenges to try to regain lost quality and standing as a national education leader. In light of the current economic crisis, competition for limited resources is fierce and the pressure is on to eliminate all but the basic "Three…

Extends the modeling system presented in Part I. This model is applied to two widely diverse educational processes: "Student Actions" and "Do Homework Problem." Its computational syntax imposes completeness criteria on the modeling and its uniformity. (AIM)
