2 open ended problems designed based on research instruments used in physics education research had been used to explore students’ conceptual and procedural understanding of vector components. With and without physical context, we asked students to find out magnitude and graphical form of vector components. The problems were given to 211 first year students of faculty of science during the...
Multiple representations are valuable tools used to help students learn how to think like physicists and understand physics concepts. Generally, in case of teaching students’ understanding of collisions, one of the available options is using the momentum bar charts. They can clearly represent the magnitude of the momentum before and after collision but they cannot be used to represent...
In this study an alternative method based on interactive instructions was included in Introductory Physics lectures to facilitate student learning in the topic of circular motion. In a preliminary study, we found that the concept of circular motion was challenging for many students although they had already learnt this topic in high school. They could not achieve the final step of...
This paper presents a further development of a so-called Ticker, a device supporting "hear and see" activity in classroom or laboratory exercises. While the original version of Ticker performs as a timing device, a new version of Ticker is improved in the sense of fast and wireless timing device. This wireless version provides the flexibility of measurements in various physics problems. The...
This Study was to mainly explore how students' opinions toward Physics Recitation for Mechanics as undergraduate compulsory course by using Peer Instructiion. Aslo it was to study students' achievement on Mechanics Recitation test. The qualitative and quantitative research approach were used to collect the data in the fall semester of 2014 at University of North Texas, USA. Both decriptive and...
Rocket propulsion is a complex and hard to understand content of Mechanics subject. For better understanding and learning perception, we established the problem solving activity called “Water rocket competition”. We assigned for every class, 10 classes and 240 students, in Grade 10 at Mahidol Witthayanusorn School for creating two home-made water rocket bottles for their class. The competition...
This research use 3-axis accelerometer sensor with a signal wirelessly, to study of the motion of a pendulum clock and calculated gravitational field. The 3-axis accelerometer sensor and wireless transmitter will pack into pendulum clock. In experimental using to variance length of wire of pendulum clock at 20 cm, 40 cm, 60 cm, 80 cm and 93 cm. The signal send from 3-axis accelerometer sensor...
