This laboratory exercise is designed to provide an understanding of the mechanical concept of impulse as it applies to human movement and athletic performance. Students compare jumps performed with and without handheld weights. Contrary to initial expectation, jump distance is increased with moderate additional weights. This was familiar to…

Climate change is one of the most serious global environmental problems and for that reason there has been lately a great interest in educating pupils, the future citizens, about it. Previous research has shown that pupils of all ages and teachers hold many misconceptions and misunderstandings concerning this issue. This paper reports on research…

Different visualization techniques have been used for teaching chemistry concepts. Previous studies have shown that when molecular animations and video demonstrations are used, students seem to better correlate all three levels of representation: macroscopic, submicroscopic, and symbolic. This thinking process allows the students to improve their…

This paper describes a unique collaboration between the College of Education (COE) and the Center for Academic Enrichment and Outreach (CAEO) at the University of Nevada Las Vegas. Here we describe our efforts to improve student science performance in traditionally underachieving urban middle schools by embracing our state's highly qualified…

The Project-Based Learning (PBL) approach enables the student to construct knowledge in his/her own way. Piaget, the founder of constructivism, saw the development of intelligence as a process involving the relationship between brain maturity and individual experience. The technology PBL (TPBL) approach confronts the student with a personal…

Merker hypothesized that because mobile creatures move around and must constantly readjust their map of the world and because the demands are so great for continually processing information for a map of the world, evolution has created a space in the brain where such preprocessing has been eliminated. This space he calls consciousness with the…

Many science education programs have recently been developed to increase girls' participation in science, however, few formal evaluations of these types of programs have been reported. The present research evaluated fifth grade girls' perceptions of a 1-day science education program. Students attended workshops describing different science fields.…

The effect of intervening use of molecular visualization software was tested on 73 first-year general chemistry students. Pretests and posttests included both traditional multiple-choice questions and model-building activities. Overall students improved after working with the software, although students performed less well on the model-building…

A formative assessment task was developed to improve the scientific report writing skills of university students. Students undertaking this task typically possessed varying levels of scientific literacy and were drawn from a cohort of mixed abilities. The assessment task involved the construction of a scientific report that included feedback from…

The study examined the effect of supplementing laboratory instruction with problem solving strategy and or practical skills teaching on students' attitude toward chemistry. A total of 286 senior secondary class II students (145 males and 141 females) drawn from four local government areas in Oyo township in Oyo state, Nigeria, took part in the…

A low-cost (US$350) satellite receiving station was assembled and operated within a classroom environment in Gainesville (Florida) on October 2001 for acquiring satellite data directly from the Advanced Very High Resolution Radiometer (AVHRR) satellites. The simplicity of the satellite signal makes this source of real-time satellite data readily…

Many biomedical research universities have established outreach programs for precollege students and teachers and partnerships with local school districts to help meet the challenges of science education reform. Science outreach programs held in university research facilities can make science more exciting and innovative for high school students…

Recent research in science education has recognized the importance of history and philosophy of science. The objective of this study is to evaluate the presentation of the Thomson, Rutherford, and Bohr models of the atom in general physics textbooks based on criteria derived from history and philosophy of science. Forty-one general physics…

This paper deals with the design process of a remote laboratory for labwork in chemistry. In particular, it focuses on the mutual dependency of theoretical conjectures about learning in the experimental sciences and technological opportunities in creating learning environments. The design process involves a detailed analysis of the expert task and…
