Article
The article introduces a low-cost Arduino sensor into the Young’s modulus determination laboratory for physics university students. A stainless steel ruler is used as a cantilever beam. Its free end attached a mass is slightly bent and released to make it oscillate as a simple harmonic motion. The Arduino sensor detects the moving mass’s frequency...

The research aims to develop the experimental set of the temperature measurement in liquid by Arduino program displaying data on a smartphone via the Blynk application. The experimental set is composed of 1) 2 liquid temperature sensors (DS18B20 model), 2) Arduino program, and 3) LED screen for showing the temperature value in unit of °C and connec...
Article
This study focused on an investigation of Thai students’ comprehension of vectors using the model analysis technique, which is based on the matrix representation of quantum physics. This technique displays students’ knowledge states and the probability of applying each mental model to solve a given vector concept. A well-known vector concept test i...

The study aimed to explore scientific reasoning abilities of engineering freshmen in Thailand (N = 680) using 24 multiple-choice questions of Lawson’s Test of Scientific Reasoning (LTSR) and find its relation with high school grade. It was found that male students (N = 442; 73±16%) outperformed female (N = 238; 67±18%) for LTSR scores. Overall, dim...
Article
This study applies the model analysis technique to explore the distribution of Thai students' attitudes and approaches to physics problem solving and how those attitudes and approaches change as a result of different experiences in physics learning. We administered the Attitudes and Approaches to Problem Solving (AAPS) survey to over 700 Thai unive...

Students always bring intuitive ideas about physics into classes, which can impact what they learn and how successful they are. To examine what Cambodian students think about projectile motion, we have developed seven open-ended questions and applied into grade 11 students before (N=124) and after (N=131) conventional classes. Results revealed seve...

This study investigated the multiple-choice test of understanding of vectors (TUV), by applying item response theory (IRT). The difficulty, discriminatory, and guessing parameters of the TUV items were fit with the three-parameter logistic model of IRT, using the parscale program. The TUV ability is an ability parameter, here estimated assuming uni...

We present a bristle tips apparatus devised to help students visualize frictional force directions in dynamic situations simply.
Article
This study aims to investigate the use of the predict–observe–explain (POE) approach integrated into large lecture classes on forces and motion. It is compared to the instructor-led problem-solving method using model analysis. The samples are science (SC, N = 420) and engineering (EN, N = 434) freshmen, from Prince of Songkla University, Thailand....

We present simple apparatus designed to help Thai high school students visualize the directions of frictional forces. Bristles of toothbrushes, paintbrushes and scrubbing brushes are used to demonstrate the frictional forces acting in a variety of situations. These demonstrations, when followed by discussion of free-body diagrams, were found to be...

The frictional force is one of the obstacles to learning in physics. By itself, this topic consists of complicated ideas. In this study, we have investigated Thai students' ideas about directions and types of frictional forces by using open-ended questions and interviews. For example, these students believed that the direction of the frictional for...
