Analysis conception of secondary student’s using four tier test on heat and temperature

The main purpose in this research is to analyse student conception about heat and temperature used four tier test question, the test consists of three question including material about temperature, temperature and heat, as well specific heat. The research has been implemented by using purposive sampling technique. The participants consisted of 67 secondary students including (23 male students and 44 female students) of senior high school in Bungo city. After the analysis obtained the largest percentage of student conception id in the category of misconception such as: (1) Objects that feel colder to the touch must be lower in temperature than objects that feel warmer to the touch; (2) Objects that have a higher temperature must have more calorific content than objects with lower temperatures; (3) Objects that are easier to increase in temperature when heated, it will be more difficult to decrease the temperature when cooled. One way to reduce student misconceptions of concept in temperature and heat material is to facilitate student learning using conceptual change model, conceptual change text or Refutation text.

The Effects of Using Predict-Observe-Explain Strategy Assisted by Conceptual Change Text towards the Conceptual Mastery of Prospective Primary School Teachers on the Matter and its Changes

This research aims at determining the differences in the increase of conceptual mastery of the matter and its changes between students who study with the Predict-Observe-Explain Strategy assisted by Conceptual Change Text (POE-ACCT) and students who study with the Expository Strategy. This study involved 63 students who were divided into 2 groups, a control group (33 students) and an experiment (30 students). The research instrument is in the form of a five-tier diagnostic test. The instrument has gone through an expert and empirical validation process. The data obtained were analyzed with descriptive and inferential statistics. The results showed a significant increase in the conceptual mastery of the experimental group (N-gain = 0.26) and in the control group (N-gain = 0.06), which were significant (p < .05). The POE-ACCT strategy was found more beneficial compared to the Expository Strategy in increasing the conceptual mastery of the prospective elementary school teachers. Although the POE-ACCT strategy provided an increase in the conceptual mastery, an increase of 0.26 was categorized in a low category and this indicated the need for improvement of the strategy.
