Often the differences students see in science and mathematics classrooms are in perspective, approach, or application. Understanding those differences can help teachers to present a unified picture of mathematics and science to their students. In this article, the science teacher is given a glimpse of the treatment of topics shared by both…

This article describes an interesting variation on the use of interactive anonymous quizzes (IAQs) in the chemistry classroom. In this variation, IAQs are used to introduce new material or topics in a course, as opposed to their traditional use for reviewing previously covered material. Two examples of IAQs used to introduce new topics in a…

An activity to excite kinaesthetically inclined students about learning physics is described in this article. Using only commonly available materials, a low cost candy floss kit is fabricated by students. A number of physics concepts are embedded contextually in the activity so that students get to learn these concepts in a real world setting…

This article describes some of the underlying conceptualizations that have gone into the work of the BEAR Center in the development of learning progressions. The core of all of these developments has been the construct map, which is the first building block in the BEAR Assessment System (BAS). After introducing the concept of a learning…

A thin-layer fuel cell is described that is simple and easy to set up and is particularly useful for teaching and classroom demonstrations. The cell is both an electrolyzer and a fuel cell and operates using a thin layer of electrolyte with a thickness of approximately 127 micrometers and a volume of approximately 40 microliters. As an…

Easily recoverable, thumb-sized pieces of high-density dry ice are conveniently produced by deposition of carbon dioxide within a test tube submerged in liquid nitrogen. A carbon dioxide-filled balloon sealed over the mouth of the test tube serves as a gas reservoir, and further permits a dramatic demonstration of both the gas-to-solid phase…

The papers in this collection provide compelling arguments that the use of Adapted Primary Literature (APL) in science education holds great promise for enriching inquiry science instruction at the secondary level. The integration of this genre of written text into science curricula illustrates the ways in which reasoning in reading and reasoning…

Polymer Chemistry days run by Bristol ChemLabS at the School of Chemistry, University of Bristol for year 10 (14-15 year olds) school students are described. Pre and post questionnaires were analysed to determine the impact on attitudes to science. There was no change in attitudes to the importance of science or practical work in science, but…

Exhibits in informal science institutions, like science centers and museums, are often designed to help people learn, but research showing the immediate impact of experiences with exhibits on understanding is limited. This dissertation tested the hypothesis that the value of first-hand experience with an exhibit is not necessarily in its immediate…

In the fall of 2008, the authors contacted a representative sample of over 3,600 high schools in the U.S.--both public and private--to determine whether or not physics was taught there. They received responses from over 99% of the schools. For the schools which indicated they were offering physics, they obtained contact information for the…

The paper is the outcome of an experiential learning episode encountered by a teacher educator (the author) with a group of student-teachers under his mentorship during a session of the practice teaching programme (2006-07) at the secondary school level. The crisis faced by a student teacher in connection with the development of a lesson template…

Teaching thinking skills to students is often associated with a thinking strategy or a specific thinking technique. The strategy or technique may refer to a series of steps that is systematically drawn up to ensure that the teaching of thinking skills takes place effectively. In the case of Malaysia, a conceptual framework of Thinking Skill…

This longitudinal, five-year study of teachers and students who had participated in a systemic reform program in science explored if (1) teacher change in practice realized during a three-year program is sustained one, two, and three years following the program, (2) student performance on state science assessments two years following studying with…

This qualitative multiple case study explored the conceptual frameworks of two congenitally blind male adolescents on the nature of matter. We examined participants' responses on four tactile investigations focused on concepts and processes associated with matter changes. The matter changes investigated were dissolution, chemical change,…

This study examined the effect of live simulation on students' science learning and attitude. A total of 311 middle school students participated in the simulation, which allowed them to access and interpret satellite data and images and to design investigations. A pre/post design was employed to compare students' science learning and attitude…
