Abstract

Conceptual understanding is one of the important indicators to achieve the goals of science teaching and learning. Learning and teaching science will always be correlated with concepts. Students^ perception of science concepts is constructed from knowledge along the learning process. In science teaching-learning, misunderstanding and misconceptions of science are influencing the performance of middle and high school students. This research^s purposes are identifying the common misconceptions and alternative ideas of science education and identifying students^ concept mastery of the topic. The participants in the current study Indonesian high school students from a senior high school (X) in Bandung, consisted of first (55, 6%), second (44, 4%) grades of high school. The instrument consisted of test items and one open-ended question related to the definition of species which were ^What do you know about blood?^ for the topic of the human body system. Each student^s score is being averaged, and research found the averages percentage of students^ scores is the same as the percentage of the correct answer. According to the results from those tables, shown the correlated data of the correct answer and misconceptions are complement each other, to become 100 %. For example, in the topic, the human body system, the first key idea, ^Blood carries oxygen to cells and carries carbon dioxide away from cells^. It has 73, 5 % correct answer and 26, 5 % misconception. The research also found that the percentage of the correct answer is the same with the percentage of concept mastery which is found 53,7 %. Based on these conditions it is very important to do improvement by carrying out more challenging learning and inviting students to construct new knowledge through appropriate learning experience to enhance students^ concepts mastery and decreasing misconceptions
