In this paper, we show a laboratory experience describing the possibility to build a sensor using a coil to measure small thicknesses of materials with the possibility of measuring temperature simultaneously, with the same built sensor. Its operation is based on the following facts: An electric current (a.c), flows through a coil and a magnetic…

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…

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…

Hands-on projects have been widely used as alternative approaches for teaching and learning of science with direct practical experience on doing to promote students' development of 21st-century skills. Here, we present an implementation of hands-on projects into teaching and learning of magnetic field topic that corresponds with indicators and…

Several suggestions for the use of Mobile Phone (MP) sensors in science teaching are found in the literature, and most of them focus on proposing physics experiments that can be conducted with the aid of the sensors that commonly exist in smartphones. The proposed experiments rely on the Bring Your Own Devices (BYOD) approach, that is, students…

The construction and operation of a prototype high-"Tc" superconducting train model is presented. The train is levitated by a melt-processed GdBa[subscript 2]Cu[subscript 3]O[subscript x] (Gd-123) superconducting material over a magnetic rail (track). The oval shaped track is constructed in S-N-S or PM3N configuration arranged on an iron…

The propose of this study is to study Physics Learning Achievement, projectile motion, using the Mathematica program of Faculty of Science and Technology Phetchabun Rajabhat University students, comparing with Faculty of Science and Technology Phetchabun Rajabhat University students who study the projectile motion experiment set. The samples are…

This research investigates the influence of computer simulations (virtual experiments) on one hand and real experiments on the other hand on the conceptual understanding of electrical charging. The investigated sample consists of students in the second year (10th grade) of three gymnasiums in Macedonia. There were two experimental groups and one…

In this study, relationship between prospective science and technology teachers' experiences in conducting Hands on physics experiments and their physics lab I achievement was investigated. Survey model was utilized and the study was carried out in the 2012 spring semester. Seven Hands on physics experiments were conducted with 28 prospective…

The progress of modern cosmology took off in 1917 when A. Einstein published his paper on general theory of relativity extending his work of special theory of relativity (1905). In 1922 Alexander Friedmann constructed a mathematical model for expanding Universe that had a big bang in remote past. The experimental evidences could come in 1929 by…

This study describes an approach for blind students thought health physics about how they could set a hypothesis and test it. The participant of the study used some health materials designed for high school blind student and tested her hypothesis with the data she gathered with those materials. It was asked that she should hypothesize which could…

This study is based on two exploratory questions with the aim of determining the relative effectiveness of two different student activities, called "Reading, Presenting and Questioning" (RPQ) and "Experimenting and Discussing" (ED), in changing students' perceptions and attitudes about the impact of physics learning on the…

Students have problems with understanding, using and interpreting graphs. In order to improve the students' skills for working with graphs, we propose Manual Video Measurement (MVM). In this paper, the MVM method is explained and its accuracy is tested. The comparison with the standardized video data software shows that its accuracy is comparable…

In order that students can develop researching, questioning, critical thinking, problem solving and decision making skills, so that they become lifelong learning individuals, they should be improved regarding their knowledge, understanding and attitude towards natural sciences. Attitudes towards physics lessons and physical experiments of high…
