This study investigated the effect of concept mapping over traditional instruction on students' understanding and retention of heat and temperature concepts. The sample of this study consisted of 5th grade students from two classes of a elementary school (n=75). One intact class was randomly assigned to the comparison group whereas the other one…

The goal of the work reported here was to help students expand their understanding of antibiotic resistance, the Central Dogma, and evolution. We developed a unit entitled "Ciprofloxacin Resistance in "Neisseria gonorrhoeae,"" which was constructed according to the principles of scientific teaching by a team of graduate students, science faculty,…

Content knowledge and pedagogical practices are of particular concern to middle school science instructors teaching density. First introduced in elementary grades with the ideas of floating and sinking, density taught in middle school is geared toward understanding through the use of mathematical formulas. Using a lesson-plan study design, the…

To increase the perceived relevance of pre-clinical science courses to undergraduates, a context-based assessment item was introduced to a genetics course that occurs early within a five-year veterinary science programme. The aim was to make a direct link between genetic concepts and the future clinical profession of the students. In the…

The objective of this study was to evaluate the effect of a dynamic software simulation on the understanding of the kinetic molecular theory by 7th graders. Students in the control group (n = 62) studied a curricular unit that addressed the differences in arrangement and motion of molecules in the three phases of matter. The experimental group (n…

The following fictional account of a seminar on complexity science and its relevance for education makes use of several real events. The first is an actual seminar that took place during the spring of 2005, in the Department of Secondary Education at the University of Alberta. The second is the collective creation of the Complexity and Education…

Context: The increasing prevalence of overweight in youth has been well chronicled, but less is known about the unique patterns and risks that may exist in rural and urban environments. A better understanding of possible rural-urban differences in physical activity profiles may facilitate the development of more targeted physical activity…

The present study investigated whether computer assisted instruction was more effective than face-to-face instruction in increasing student success in physics. The study was conducted in the spring semester of 2006 at the Department of Science and Mathematics for Secondary Education at Hacettepe University. Seventy-eight freshman students from…

Middle school science teachers report using textbooks regularly although these textbooks have been criticized for not following standards-based principles for concept learning, and student reading achievement has been stagnant for 20 years. Effective strategic reading instruction has been documented for middle school students but few teachers use…

Bernoulli's principle is being misunderstood and consequently misused. This paper clarifies the issues involved, hypothesises as to how this unfortunate situation has arisen, provides sound explanations for many everyday phenomena involving moving air, and makes associated recommendations for teaching the effects of moving fluids.

Many of the basic concepts involved in the process of scientific inquiry can be represented by analogy to a simple game called Battleships. The same processes used in this child's game demonstrate what role hypothesis generation and testing play in the search for truth in nature. The analogy can also be extended to demonstrate how scientists…

This study extends ongoing work to identify difficult concepts in thermal and transport science and measure students' understanding of those concepts via a concept inventory. Two research questions provided the focal point: "What important concepts in electric circuits and engineering mechanics do students find difficult to learn?" and…

A study on the effect of a structured problem-solving strategy on problem-solving skills and conceptual understanding of physics was undertaken with 189 students in 16 disadvantaged South African schools. This paper focuses on the development of conceptual understanding. New instruments, namely a solutions map and a conceptual index, are…

Biochemistry courses at Seattle University have been taught exclusively using process oriented guided inquiry learning (POGIL) without any traditional lecture component since 1997. In these courses, students participate in a structured learning environment, which includes a preparatory assignment, an in-class activity, and a follow-up skill…

During the past few years the authors have developed a new approach to the teaching of physical science, a general education course typically found in the curricula of nearly every college and university. This approach, called "Physics in Films" (Efthimiou and Llewellyn 2006 Phys. Teach. 44 28-33), uses scenes from popular films to illustrate…
