Light pollution is nowadays well known all over the world and may negatively cause disturbance to human and have diverse effects. This study aims to identify the views and opinions of the Islamic University of Gaza students on light pollution and then to create awareness among them about the risky problem facing rapidly our society. The study is…

Trillion Theory (TT), a new theory, estimates the cosmic origin at one trillion years. This calculation of thousands of eons is based upon a growth factor where solar systems age-out at a max of 15 billion years, only to recycle into even larger solar systems, inside of ancient galaxies that are as old as 200 billion to 900 billion years. TT is a…

This study explored how research-based physics tutorials help students use argumentation in a small group-work activity. The participants were four first-year non-major physics students taking algebra-based introductory physics course in an urban university in the southeastern region of United States (US). The content analysis was conducted to…

The purpose of the current research was to determine the opinions and alternative concepts of the pre-service science teachers about the functions of the elements found in a simple electric circuit. The current research was carried out with the participation of the first-year students attending the Science Teaching Department of a state university…

The first law of thermodynamics does not forbid heat engines with 100% thermodynamic efficiency; it is the second law of thermodynamics which states that heat engines cannot obtain 100% efficiency. Can the first law ever show this second law result? Yes. We show that the first law alone can show that some heat engines cannot achieve efficiencies…

This study examined effects of the Polya's problem solving Technique (POPSOT) as observed by Shaibu (1987) in Atadoga (2010) and conventional problem-solving Technique (CONPSOT) on cognitive achievement of physics students. A pre-test post-test quasi experimental design used adopted for the study. The sample comprised of 102 senior secondary two…

Science education has an important role in children's understanding of the world, making the right decisions in accordance with their perceptions, using problem solving skills and scientific attitudes. In this study, the effects of activities prepared by considering the needs of visually impaired students on the development of scientific process…

This paper discusses the importance of one of the most crucial elements in science and technology education: the development of the individual capacity to cope with new problems. Also, discuss the importance of being aware of the existence of "formative objectives" and "tacit knowledge". In the planning of a course, taking into…

In this paper, the level of conceptual understanding of Newtonian mechanics among Afghan school and university students in Kabul, Afghanistan was investigated. This study employed a quantitative descriptive survey method where the Pashto version of the Force Concept Inventory (FCI) was given to a random sample of 216 students from two schools and…

According to the Felder and Silverman Learning Styles Model (FSM), students have learning preferences regarding how information is obtained, processed, perceived and understood. The Index of Learning Styles (ILS) is an online questionnaire created by Felder and Soloman to classify students according to their learning styles. With a priori…

Students' responses to energy & momentum (EM) concepts were investigated. EM concepts are fundamental and crosscutting in physics. A standardized Energy and Momentum Conceptual Survey (EMCS) test were used to collect quantitative data from 108 first year science students enrolled in a university in Ethiopia. Concentration analysis was used to…

Concept inventory (CI) tests are typically used to measure students' general knowledge before and after instruction. We find issue with the current format of these tests, which some researchers claim, measure students' misconceptions, since the answers choices given to students do not consider their prior knowledge. We particularly analyze Force…

A recent textbook research, carried out on a sample of 20 American physics textbooks, shows that the authors mainly keep the old definition of weight. According to that definition, the weight of a body is the gravitational force on the body. In such a conceptual frame, the objects in the spaceship are "apparently weightless" because they…

The well-known historical development of Electromagnetism, strongly influenced by the work of Faraday and Maxwell, has led to the introduction of the magnetic field as an important component to explain the diverse phenomena of electromagnetic induction. This historical development is compared in the form of a thought experiment with a possible…

The classical physics treatment of "Electromagnetic Induction" is based on Faraday's Law and Lorentz Force. This paper presents an alternative approach, based on Wilhelm Weber´s Fundamental Force Law of Electrodynamics. It covers mutual induction, self-induction, parallel and anti-parallel currents, and currents in the same and opposite…
