It is commonly argued that socio-economic inequalities can explain many of the differences in achievement and participation in science education that have been reported among countries and among schools within a country. We addressed this issue by examining (a) the relationship between variables associated with socio-economic background and…

Analysis of views from a select group of Kenyan science teachers regarding the effect of student learning experiences on their teaching after implementing a contextualized science unit revealed that the teachers' (a) literal interpretation and adherence to the official curriculum conflicted with the students' desires to understand scientific…

The ability to listen closely, speak clearly, write coherently, read with comprehension, and to create and critique media offerings in science contexts is essential for effective science teaching. How might instructors develop such abilities in a physics course for prospective elementary and middle school teachers? We describe here such a course,…

This article describes a one-semester anatomy and physiology course that is currently offered through the concurrent enrollment program at the University of Minnesota. The article explains how high school teachers are prepared to teach the course and describes efforts to promote program quality, student inquiry, and experiential learning.…

"Next Generation Science Standards" identifies the science all K-12 students should know. These new standards are based on the National Research Council's "A Framework for K-12 Science Education." The National Research Council, the National Science Teachers Association, the American Association for the Advancement of Science,…

This quantitative study (n = 247) explores whether preservice science teachers express science-specific identities that reflect multiple areas of their beliefs (e.g., purpose for science teaching, inclusion of science-technology-society-environment issues into science teaching, and nature of science) as well as other individual characteristics…

This story is a chemical mystery with an emphasis on qualitative analysis, metallurgy, and gravimetric analysis. It is, as well, yet another article in the continuing series, created by Thomas Waddell and Thomas R. Rybolt, that presents a scientific problem in mystery format in the context of the popular and beloved characters of Sherlock Holmes…

This study investigates pre-service teachers' TPACK development in a secondary science teacher education program that combined a content-specific technology integration course with extensive field experience. Both quantitative and qualitative data were collected. Quantitative data were collected through a pre-post administration of the…

This webinar explored how the Next Generation Science Standards (NGSS) provide an instructional framework to support professional growth and inform teacher evaluation systems for science instruction. This Q&A addressed the questions participants had for Dr. Wilson and Jody Bintz following the webinar. The webinar recording and PowerPoint…

Since 2003, international project PISA evaluates 15-year old students in solving problems that include "decision taking", "analysis and design of systems" and "trouble-shooting". This article presents the results of a pilot research conducted with 215 students from first to fourth grade of a high school in Sarajevo…

The purpose of this study was to explore the motivation of a group of township learners who participated in a science fair known as Expo, by using phenomenography to explore their conceptions and experiences of Expo. The data comprised paragraphs written by the learners before the regional Expo and focus group interviews conducted afterwards. The…

Students learn science best with activities that mirror the way scientists work. This article describes how geologists investigate groundwater flow systems in areas of karst topography--geologic formations shaped by dissolving bedrock--and provides a way for students to replicate this research. Students also use electric current to model water…

The topics of nature, for example semiochemicals, are motivating topics, which can be used to teach organic chemistry at high school level. The history, classifications, a few important applications of semiochemicals, and an semiochemical that can be synthesized in the laboratory are presented. The laboratory synthesis is carried out through the…

The objective of this naturalistic study was to explore, model and visualise the learning progress of 13-year-old students in the domain of evolution theory. Data were collected under actual classroom conditions and with a sample size of 107 learners, which followed a teaching unit on Darwin's theory of natural selection. Before and after the…

Scientific and technological developments resulted in an increase in the requirement of education in the society. In addition to this, the expectations from teachers differed and the need for more qualified teachers also increased. One of the factors affecting the quality of teachers is their motivation. In this research, it was aimed to reveal…
