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.

Alternative learning model in physics learning: Effect of the conceptual change model with cognitive conflict on critical thinking skill

The purpose of this study was to apply the Conceptual Change Model (CCM) containing cognitive conflicts and to find out the difference in their effects on students' critical thinking skills. This type of research is a quasi-experimental study with an Only-Posttest design. The sample in this study was 91 students at senior high school in Lombok, Indonesia. The sampling technique used in this research is simple random sampling. Students are divided into three sample groups: experiment class, control 1 class, and control 2. Critical thinking skills are measured based on five aspects: basic clarification, basic decisions, inference, evaluation, and further explanation. The test used to measure critical thinking skills is a description test. The material chosen is motion along a straight line. This research was tested by ANOVA 1 way. The test results show differences in the critical thinking skills of the three sample groups in the motion and straight line material. This shows that CCM containing cognitive conflict can be used as alternative learning to improve critical thinking skills. Subsequent research is carried out for different materials and different areas, but it should be noted that this learning is suitable for materials that experience many misconceptions.

The Effect of Conceptual Change Using The Adobe Quran on Misconception, Self-Regulation, Self-Efficacy, and Self-Confidence

<span lang="IN">This study aims to (1) determine the effect of conceptual change using the adobe Quran on the reduction of misconceptions, (2) determine the effect of conceptual change using the adobe Quran on self-regulation, self-efficacy, and self-confidence. The population in this study were all students of class XI in 3 schools. At Islamic Senior High School 1 Bandar Lampung and Senior High School 1 Negara Batin with a total of 6 classes with a total of 95 and 87 students respectively. Senior High School 2 Sekampung with a total of 4 classes and a total of 70 students. This study used a weak experiment with a one-group pretest-posttest design. So that there are 3 classes as research classes namely, class XI MIA 1, XI MIA 2, and XI MIA 6 at Islamic Senior High School 1 Bandar Lampung, class XI MIA 1, XI MIA 2, and XI MIA 3 at Senior High School 2 Sekampung and Senior High School 1 Negara Batin. The data in this study were obtained through a misconception test accompanied by CRI (Certainty of Response Index) and self-regulation, self-efficacy, and self-confidence questionnaire. Data were analyzed using a one-sample t-test. This study concludes that the conceptual change model using the adobe Quran can reduce misconception and increase self-regulation, self-efficacy, and self-confidence. The researcher suggests applying the conceptual change model using adobe Quran to other learning materials so that it can help in reducing misconceptions in other learning materials.</span>

Reduction of Students’ Biological Misconceptions through the Conceptual Change Model Integrated with Android-Based Quran

This research aimed to reduce students’ misconceptions using a conceptual change model assisted by the integrated Android-based Quran. The study used a quasi-experimental design with a one-group pretest-posttest design. The study involved 95 eleventh-grade students MAN 1 Bandar Lampung. The research instrument was multiple-choice questions equipped with a certainty of response index (CRI) developed based on the revised Bloom taxonomy indicator. The data collection techniques used were tests (pretest and posttest). The results of the study obtained a reduction value of misconceptions in the pretest, namely understanding the concept of 47 % (moderate), misconception 48 % (moderate), and not understanding the concept of 5 % (low). The posttest score decreased (reduced) the proportion of misconceptions to 42 % (moderate), not understanding the concept to 4 % (low), and understanding the concept to 55 % (moderate). The hypothesis testing employed was the one-sample t-test. Therefore, H1 was accepted. It means that the conceptual change model (MCC) with Android-based Quran media can reduce students’ misconceptions with a criterion of 0.71 (medium interval). Thus, the results of this research can add to the treasury of studies on the reduction of misconceptions through the MCC model based on the Android-based Quran media. Also, as a practical use for teachers to deepen the concept of biology to guide students to understand the concept of the material better correctly.

Misconceptions, conceptual pluralism, and conceptual toolkits: bringing the philosophy of science to the teaching of evolution

This paper explores how work in the philosophy of science can be used when teaching scientific content to science students and when training future science teachers. I examine the debate on the concept of fitness in biology and in the philosophy of biology to show how conceptual pluralism constitutes a problem for the conceptual change model, and how philosophical work on conceptual clarification can be used to address that problem. The case of fitness exemplifies how the philosophy of science offers tools to resolve teaching difficulties and make the teaching of scientific concepts more adequate to the actual state of affairs in science.

PENGGUNAAN MODEL CONCEPTUAL CHANGE PADA INSTRUMEN THREE-TIER-TEST DAN LKPD

There are still many misconceptions in the buffer solution material based on the results of pre-research that has been done. Therefore, it is necessary to to make efforts to reduce misconceptions. This research aims to determine the validity of the three-tier-test diagnostic test instrument and Student Worksheet (LKPD) to reduce student’s misconceptions through conceptual change model on buffer material. This research and development method uses a 3-D model which is a modification of the 4-D model, namely (1) define; (2) design; and (3) development. The validity of the instrument and LKPD in terms of content validity and construct validity. The content validity of the instruments and LKPD respectively obtained an average percentage of 94.00% and 92.44%. While the construct validity of the instruments and LKPD respectively obtained an average percentage of 91.00% and 86.47%. This results shows that the three-tier-test diagnostic test instrument and LKPD through conceptual change model developed were declared very valid.
