Part 2 of the findings are presented of a quantitative study (n = 125) on basic quantum chemical concepts taught at twelfth grade (age 17-18 years) in Greece. A paper-and-pencil test of fourteen questions was used that were of two kinds: five questions that tested recall of knowledge or application of algorithmic procedures (type-A questions);…

This study compared inquiry and non-inquiry laboratory teaching in terms of students' perceptions of the classroom learning environment, attitudes toward science, and achievement among middle-school physical science students. Learning environment and attitude scales were found to be valid and related to each other for a sample of 1,434 students in…

The standards movement arrived in the mid-1980s and new curriculum frameworks of instruction were crafted for the reform of science and mathematics curriculum, instruction, assessment, and professional development for teachers. Today, the warning calls about science and mathematics education, the fading STEM (science, technology, engineering, and…

The decline in the popularity of physics over the period of secondary schooling and its consequent low uptake at A-level and beyond continues to cause concern on educational and economic grounds. The aim of this study is to explore whether physics might be made more attractive to students by employing an extended range of classroom and laboratory…

The present paper reports the design process and the experimentation of a teaching-learning sequence about the concept of mechanical wave propagation and the role played by media where waves are propagating. The sequence focuses on the central issue of the relationships between observable phenomena, like macroscopic behaviours of waves, and their…

The use of podcasting has grown exponentially. Research projects are racing to keep up with this growth to understand implications for learning and instruction. This project specifically attempts to understand if the use and development of podcasts by students for students influence learning in a 7th grade science classroom. Using a technology…

The American Association for the Advancement of Science (AAAS) was tasked with identifying the key science concepts for science literacy in K-12 students in America (AAAS, 1990, 1993). The AAAS Atlas of Science Literacy (2001) has organized roughly half of these science concepts or benchmarks into fifty flow charts. Each flow chart or strand map…

A one day practical course in molecular biology skills suitable for year 12/13 students is described. Colleagues from partner schools and colleges were trained by university staff in basic techniques and then collaborated in the design of a course suitable for their own students. Participants carried out a transformation of "E.coli"…

Contextualizing science instruction involves utilizing students' prior knowledge and everyday experiences as a catalyst for understanding challenging science concepts. This study of two middle school science classrooms examined how students utilized the contextualizing aspects of project-based instruction and its relationship to their science…

This study explores the extent to which the term "sex hormone" is used in science textbooks, and whether the use of the term "sex hormone" is associated with pre-empirical concepts of sex dualism, in particular the misconceptions that these so-called "sex hormones" are sex specific and restricted to sex-related physiological functioning. We found…

This research addresses the effectiveness of an interactive learning environment, Inquiry Island, as a general-purpose framework for the design of inquiry-based science curricula. We introduce the software as a scaffold designed to support the creation and assessment of inquiry projects, and describe its use in a middle-school genetics unit.…

This paper traces the development over several years of an initiative, involving student journals, that was introduced into a tertiary science education course for pre-service teachers in order to improve communication between the lecturer and students. The narrative recounts how the nature and uses of the journals evolve subsequently as a result…

The article is about the collaboration between two classrooms that enabled a second grade class to participate in a high school biology class. Through the use of modern video conferencing equipment, Mrs. Culbert, with the help of the Dalton State College Educational Technology Training Center (ETTC), set up a live, two way video and audio feed of…

This study describes the influence of a secondary science methods program on secondary science preservice teachers' views and enactment of nature of science and inquiry-based instructional practices. Built into the structure of this program were three cycles of practice teaching and reflection in which the preservice teachers focused on key…

The purpose of the study is to compare problem based learning (PBL) and lecture-based learning (LBL) in Hong Kong secondary students' science achievement. Secondary One students were divided into two groups: group A (n = 37), was taught two topics: "Human Reproduction" and "Density" through PBL; group B (n = 38) was taught the…
