The science teacher in the modern high school acts as the designer and driver of the in-class practice. In this role, the teacher must broadly assess the effect of the practice on the student. This would rely on accurate self-knowledge of how they act in class and impact their students. In this study we explore these issues by comparing the…

Marie Ståhl and Anita Hussénius have defined what discourses dominate national tests in chemistry for Grade 9 in Sweden by using feminist, critical didactic perspectives. This response seeks to expand the results in Ståhl and Hussénius's article "Chemistry inside an epistemological community box!--Discursive exclusions and inclusions in the…

I examine the levels of educational emphases that science teachers in Evangelical Protestant (EP) schools place on (i) teaching basic content knowledge, (ii) improving scientific reasoning skills, and (iii) presenting real-world applications of science. Using a nationally representative sample of US ninth-graders, I find differences in these…

Literacy skills are critical to students' academic achievement and setting them on a path to successful high school graduation and readiness for college and careers. "Passport Reading Journeys" [TM] is a supplemental literacy curriculum designed to help improve reading comprehension, vocabulary, word study, and writing skills of…

An instructional program using four simulation applets was used to facilitate understanding of gas and liquid pressure concepts among twenty-two students in a Year 9 class from an independent secondary school in Singapore. A comparison group consisting of twenty-two students was taught using traditional didactic, chalk-and-talk instruction.…

In 2008, this magazine ran an article describing the results of a survey of the eighth-graders who were about to begin their first physics course at Weston High School. The results helped this coauthor (BK) and his high school colleagues better understand the expectations of the incoming students. It seemed useful, however, to conduct another…

This study investigated three questions: (1) What are Lebanese secondary school (Grade 9-12) biology teachers' and university biology professors' positions regarding biological evolution?, (2) How do participants' religious affiliations relate to their positions about evolutionary science?, and (3) What are participants' positions regarding…

A New Turkish Physics Curriculum has been constructed between the years 2006-2009. It is to the gaining of new perspectives. The purpose of this paper, therefore, is to reflect on the nature of the New Turkish Physics Curriculum (NTPC). To this end, the authors focus on the five themes of the NTPC using a document analysis method: basic reasons…

In Australia, there is a crisis in science education with students becoming disengaged with canonical science in the middle years of schooling. One recent initiative that aims to improve student interest and motivation without diminishing conceptual understanding is the context-based approach. Contextual units that connect the canonical science…

This study involved the evaluation of the efficacy of a planned instructional program to facilitate understanding of the macroscopic, submicroscopic and symbolic representational systems when describing and explaining chemical reactions by sixty-five Grade 9 students in a Singapore secondary school. A two-tier multiple-choice diagnostic instrument…

This paper reports on an investigation of the effectiveness an intervention using several different methods for teaching solution chemistry. The teaching strategy comprised a four-step approach derived from a constructivist view of learning. A sample consisting of 44 students (18 boys and 26 girls) was selected purposively from two different Grade…

Research suggests that language-based activities should be an integral part of science teaching and learning and that these are even more important in minority-language contexts. The present cross-case study investigates how literacy is enacted in francophone science classrooms. Three francophone teachers were observed while they taught Grade 9…

No other food industry depends so heavily on a wild caught resource than those associated with aquatic food products. Domestication of fish, shellfish, and other aquatic resources production has lagged behind other terrestrial livestock products; however, demand for these aquatic natural resources has continued to increase dramatically. Teaching…
