Abstract

Nowadays, the lack of a facility is one of the main problems in physics education for developing countries. To solve the problem by use of the modern technology which develop around the world obviously, a teaching material in learning alternating current (AC) circuit as one of the most difficult theory in physics for secondary school students has been investigated using a soundcard oscilloscope with the laptop computer. Experiments for the electrical resonance in LCR circuits have been investigated using the sound card oscilloscope; experimental results were compared to that measured by the conventional oscilloscope system. As expected, the investigated soundcard oscilloscope experiments show a good performance; the magnitude of electrical current as a frequency response proves the effectiveness of the teaching material in physics education that shows kind of limited function of soundcard oscilloscope that utilizes as a benefit in a simple experiment. For the further work, the teacher can utilize and develop this software for the other teaching materials for example related to traditional music or traditional apparatus which tend to find around student’ home or school, so students can understand more deeply about the concept of alternating current in many cases and more interesting classes can be created.

Abstract

The identification of misconception in the Physics or Science learning all this time mostly used the two-tier or three-tier diagnostic test. There were several reasons why both test forms used, such as to make sure whether the students guessed the answers or understood the concepts. Besides, through the use of both tests the students' confidence in choosing the answers could be identified. However, there was no explanation or study on the most effective test to identify those misconceptions. The purpose of this study was to know the effect of the one-tier, two-tier and three-tier diagnostics test toward the students' answer pattern, confidence level, and understanding on the concept of anatomic nuclear. The respondents which were used in this survey research were 88 the students attending Atomic Nuclear course in Physics Education Department, Faculty of Teacher Training and Education, Syiah Kuala University. Some tests were consecutively given to the 88 respondents, the test participants could continue to the next test if they finished all questions in the previous test. The data collection used the instrument of basic Physics preconception test (Tes Pemahaman Konsep Fisika Inti/TPKFI) in the form of one-tier, two-tier and three-tier multiple choice with eight multiple choice items. The test was developed by researchers with difficulty index = 0.35, discrimination index = 0.31, validity= 0.35, and reliability= 0.90. The data analysis result showed that even though the students' answer patterns were the same for all types of diagnostic tests, there was a convincing change in the students' concept understanding and confidence between the two-tier and three-tier. From this research, it could be inferred that the identification of the students' misconception in the Science learning would be better (had high confidence), if the diagnostic test used was higher, that was three-tier, four-tier, and thus on.
