Misunderstanding is one of the causes of junior high school students in the city of Lamongan learning difficulties, especially studying physics material. The aim of this study was to investigate whether the three-tier test able to identify student misconceptions. Based on the research objectives to be achieved, this research is a descriptive study using descriptive qualitative methods in explaining the research results. The technique of collecting data through tests is by using a Three-Tier Test diagnostic instrument and open interview. Diagnostic results data are expressed in terms of percentage of the students’ conception categories. The sample of this research is the students who have received the Heat material, seventh graders. The subjects of this study were grade VII students totaling 150 students with details of 60 male students and 90 female students with age around 12 to 13 years old. Besides using written tests, interviews were conducted on several students to verify the results of the three-tier test. From the analysis of three-tier test diagnostic data students showed that from 47% including the criteria to master the concept, while the remaining 38% experienced misconceptions, 5% guess or not believe in the answers, and 10% don’t know the concept. Conclusions of this study is the three-tier test that has been developed on Heat topic is able to identify misconceptions students quickly and accurately. Therefore, a three-level diagnostic test tool that has been developed to diagnose students ‘misconceptions about temperature and heat materials can identify students’ misconceptions quickly and accurately.

Student learning outcomes are still low due to the use of learning models that are less varied. Therefore, researchers apply the cooperative learning model type group investigation in learning science. This study aims to describe the influence of the cooperative learning model type group investigation on the learning outcomes of science materials in the fifth grade students of SDN 1 Banjarejo. This type of research used is quasi-experimental design with nonequivalent control group design. The sample of this research is the VB class SDN 1 Banjarejo experimental class and class V SDN 1 Banjarejo as the control class. Data collection techniques for learning outcomes use multiple choice tests and descriptions. Learning outcomes data were analyzed by independent t-test and gain test. The results of the analysis of the pretest data showed that there was no difference in the average pretest score between the two samples. The results of posttest data analysis showed that there were differences in the average posttest scores of the experimental and control classes, with the difference in the average experimental class being higher at 5.50. Large increase in the average normalized gain in the experimental class by 0.41 (medium), while in the control class by 0.29 (low). These results provide the conclusion that the cooperative learning model type group investigation has a significant and positive influence on science learning outcomes in elementary students.

<em>This study aimed to determine the effectiveness of science worksheets with cognitive conflict strategies to reduce student heat misconceptions. This research was conducted at SMP Negeri 1 Lamongan by using one group pretest-posttest design. The data obtained in this study is quantitative data, and the number of students in VII grade is 50, students are called to complete the research if the proportion of correct answers is more significant than the standard achievement test. While the class is said to complete the study if 85% of students can reach the standard test criteria. The researcher obtained information about the level of mastery of students' concepts by using N-gain, one method in the descriptive qualitative analysis. It shows the different levels of student mastery before and after treatment given. The effectiveness of the Science Worksheet will be analyzed from the acquisition of learning outcomes. This yields 0.94 points which means that the value of N-Gain is in the sufficient category, it can be said that the application of the Science Worksheet with cognitive conflict strategies can reduce heat misconceptions of junior high school students.</em>

Students, basically, possess prior knowledge or conception regarding a concept, even before they study it formally in the school. Sometimes, their conceptions are inconsistent with scientific concept and resulting misconceptions. Some studies found that students encounter misconception of some concepts, particularly in Physics. Three-tier Test is an instrument used to identify student’s misconception and lack of knowledge. A misconception should be differentiate from a lack of knowledge because remediation of a misconception is more difficult than remediation of a lack of knowledge. Besides, both of them may entail different instructional methods. This study focused on diagnosing students’ misconceptions of heat using Three-tier Test. The study is aimed to explain in what concepts the students encounter misconceptions of heat and to explain the prevalence of students’ misconceptions of heat. The method used in this study was a descriptive-exploratory research with non-experimental design. The sample of this study was 150 Grade VII students of five different State Junior High School in Lamongan, East Java. The data was collected through written test using Three-tier Test and administered once. The results showed that students encounter misconceptions in 6 concepts of heat comprising energy, heat, temperature, mass, specific heat capacity, vaporizing, boiling, pressure, boiling point, freezing, and freezing point. Moreover, the results showed that 88% of the students encounter misconception, where the most frequently appeared is misconception about energy and heat that is objects could have a certain quantity of heat in them.
