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 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…

Many physics professors have difficulties to know and assess in real time the learning of the students in their courses. Nevertheless, today, with Internet and the new technology devices that the students use every day, like smartphones, such tasks can be carried out relatively easy. The professor pose a few questions in "Socrative," the…

There is a general agreement that critical thinking is an important element of 21st century skills. Although critical thinking is a very complex and controversial conception, many would accept that recognition and evaluation of assumptions is a basic critical-thinking process. When students use simple mathematical model to reason quantitatively…

The purpose of this study was not only to report the development process of the studio model, but also to determine the students' perceptions about the studio model. This model retains the large lecture component but combines recitation and laboratory instruction into studio model. This research was based on qualitative analysis. The data of the…

The research examined the effect of a teaching strategy emphasizing on instructional congruence on students' interests towards learning science. This study was conducted in three "low performing" secondary schools in Penang, Malaysia. There were 214 students involved in this study. A questionnaire was utilized to collect data on…
