Physics teachers need diagnostic competence to effectively identify students' misconceptions, but studies have yet to sufficiently investigate how this competence can be advanced through various instructional strategies. In this study, we compared a problem-solving strategy against an example-based strategy in advancing diagnostic competence in…

'A lack of prior knowledge in the other discipline' is often given by geoscience instructors to explain why students struggle to apply knowledge from other disciplines to the Earth. We examine this assumption by considering the disciplinary crossing of buoyancy (physics) to isostasy (geoscience). We investigate the teachers' perspective through…

One of today's challenges in science education involves the development of appropriate conceptions of inquiry teaching and realizing how these experiences can support students' understanding of the nature of science and inquiry (NOS and NOSI). To meet this challenge, we developed a course for in-service science teachers, in which…

The prime purpose of this investigation was to improve Pre-service Chemistry Teachers (PCTs) understanding of reaction related concepts of Aliphatic Hydrocarbons (AHCs). Participants were 12 PCTs selected from a pool of 87 second year PCTs taking Introductory Organic Chemistry course in Arbaminch college of Teachers Education, Southern Nations,…

In this study, collaborative lesson planning (CLP) was a positive 'dissonance' to the teachers' individual lesson planning practices. Thirty teachers grouped into grade-level teams (five members) participated in the study. Data transcripts from audio- and video-recordings, formal and informal interviews, and written evaluation forms were…

This study aims to examine the thoughts of fourth-year pre-service science teachers about the nature of science. For this purpose, the study preferred the qualitative research method and phenomenology design. Participants consisted of nine pre-service science teachers. Participants wrote a self-evaluation report after the nature of the science…

Focus of this article is the current situation characterized by students' de-rootedness and possible measures to improve the situation within the frame of education for sustainable development. My main line of argument is that science teachers can practice teaching in such a way that students are brought in deeper contact to the environment. I…

Misconceptions are a barrier to understanding biology hence, to promote meaningful learning, it is necessary to overcome these difficulties with the help of different instructional methods rather than traditional instructional methods. Therefore it could be very interesting to find out "how students' prior knowledge of genetics affects…

One could argue that attitudes, knowledge, beliefs, and differing definitions and perceptions can all affect science teachers' motivation to engage in inquiry practices. Better understanding what motivates science teachers' instructional behaviors can result in improved efforts by researchers to align their instruction with quality inquiry-based…

The purpose of this study was to explain middle school teachers' decisions for planning a science unit of instruction (reflection on action) and their decisions when enacting this planned unit (reflection in action) using the new teacher professional knowledge and skill (TPK&S) model as a guiding framework. In addition, this study specifically…

Teacher leadership has been recognized as a necessary ingredient to support educational reform efforts. Leaders provide the needed expertise to ensure reforms are successful in promoting student learning. The overarching goal of the "Leadership in Freshman Physics" program is to support a cadre of teachers-leaders who will become advocates for…

This article provides support to college science instructors who wish to implement new strategies to probe student understanding, not to prescribe a single best way to conduct a college science course.

Earth science teachers know how frustrating it can be to spend hundreds of dollars on three-dimensional (3-D) models of Earth's geologic features, to use the models for only a few class periods. To avoid emptying an already limited science budget, the author states that teachers can use a simple alternative to the expensive 3-D models--sand. She…

The purpose of this study was to examine changes in personal science teaching self-efficacy (PSTE), outcome expectancy (STOE), and science conceptual understanding and relationships among these in preservice teachers. Seventy preservice teachers enrolled in science teaching methods courses participated in this study. PSTE, STOE, and science…

Reform documents have provided a framework for advancing science education (e.g., The Australian National Science Standard Committee, 2002), but omit the need to assess preservice teachers prior knowledge for designing effective learning programs. A pretest-posttest 34-item survey linked to the course outcomes (associated with four constructs)…
