There is emerging evidence to suggest community-based interventions can change community-wide behaviors and attitudes toward cardiovascular health. This article describes a partnership between an academic institution and a community nonprofit organization to develop and implement a cardiovascular health promotion program targeting at risk high…

The use of audience response system (commonly known as clickers) supports communication and interactivity in class by allowing the instructor to ask thought-provoking questions and encouraging students to articulate and reflect their thinking, reveal misconceptions, probe the knowledge and follow their progress in the course. Recent studies on the…

The study aims at introducing the features of the computerized educational games in sciences at the elementary school in Jordan according to the specialists in teaching science and computer subjects, through answering some questions such as: What are the features of the computerized educational games in sciences at the elementary schools in Jordan…

This study examined educational factors that positively influenced the confidence of students training to be elementary science educators (self efficacy). Specifically, it compared the impacts of a science method course and a practicum teaching course on Kuwait University students. Using a pre/post design, The Science Teaching Efficacy Belief…

The study examined the effect of concept-mapping and problem-solving teaching strategies on achievement in biology among Nigerian secondary school students. The method used for the study was a quasi-experimental pre-test treatment design. One hundred and thirteen senior secondary three (S.S. 111) students randomly selected from three mixed…

Chemistry is a subject area that is difficult to understand for some students as it contains abstract concepts, such as mole, molecule and particle. The mole concept is one of the most important topics in which students have difficulty in understanding. There are many studies in the literature on the mole concept. Students who do not fully…

This study has identified the effectiveness of using portfolios for the prospective teachers as a tool of an explicit, reflective, and instructional approach in science education. Early childhood science method courses in a college for unskilled early childhood teachers influence their theory and practice toward science teaching. It describes…

Students of a required biology course for non-science majors were given an opportunity to take online multiple choice quizzes during the weekend interval between classes. Incentives were that they would be given extra credit for their participation. Questions from the quizzes were then placed on the next exam. After the exam was given, the number…

We report on research that explores students' literacy practices in six Norwegian primary school science classrooms during integrated science-literacy instruction. The study combines observational video data and interview data to examine students' encounters with and use of text, along with their views and experiences related to science…

We present experiments giving new insights into the classical light-emitting pickle experiment. In particular, measurements of the spectra and temperatures, as well as high-speed recordings, reveal that light emission is connected to the polarity of the electrodes and the presence of hydrogen.

The purpose of this paper is to introduce students of science and engineering to the orbital lifetimes of satellites in circular low Earth orbits. It is only necessary to know about classical mechanics for this calculation. The orbital decay of satellites is due to the interaction of the satellite with the surrounding gas, atmospheric drag.…

A method to determine the temperature dependence of copper wire resistance is described in this paper.

We present a general physics laboratory exercise that centres around the use of the electrocardiogram sensor as an application of circuits and electronic signal filtering. Although these topics are commonly taught in the general physics classroom, many students consider topics such as alternating current as unrelated to their future professions.…

This paper examines the common confusion associated with the meaning of mass encountered in modern textbooks, and describes some of the misconceptions to be found in the teaching of mechanics. A new teaching approach is suggested, which may provide a more logical basis for these important ideas.

This paper gives the solution and analysis of projectile motion in a vacuum if the launch and impact heights are not equal. Formulas for the maximum horizontal range and the corresponding angle are derived. An Excel application that simulates the motion is also presented, and the result of an experiment in which 38 secondary school students…
