The ability to solve problems is a process in which a person identifies a situation, formulates a hypothesis, verifies a hypothesis made by digging up data, and restarts the hypothesis made to become a generalization (Purwanto, 1999). The focus of this research is to analyze the influence of the use of the Kampung Warna Warni Jodipan as a source of learning for students' ability to solve problems in MTs Attaraqqie Malang on the theme of tackling environmental pollution. This study uses an experimental research design in the form of a Quasi-Experimental Design with the type of pretest posttest control group design. The sample in this study were students of class IX A and IX D with purposive sampling technique. Data collection techniques using test questions in the form of problem description. The data analysis technique in this study was to use the independent sample t-test. The results of this study indicate that there is a significant influence on the use of the Kampung Warna Warni Jodipan as a source of learning for students' problem solving abilities, this is evidenced by the results of the independent sample t-test which shows that there is a significant influence on the use of the Kampung Warna Warni Jodipan. , with tcount> ttable which is 5,450> 2,000. This shows that there are significant differences in the ability to solve problems in the experimental and control classes.

This study aimed to answer whether using chessboard technique in responding to short story develops student’s speaking skill or not. The method used in this study was one of the quasi-experimental designs: pretest-posttest non-equivalent comparison control group design. The population of the study was the eleventh-grade student at SMA N 12Palembang and the sample were taken from the population by using purposive sampling. The data were collected by using two instruments, test and questionnaire. The test wasgiven twice to the experimental and control group, as the pretest and the posttest. Thequestionnaire was distributed to the experimental group after conducting the treatment to get more information related to the problem of the study. To verify the hypothesis, thedata from pretest and posttest on the experimental and control group were analyzed byusing paired sample t-test and independent sample t-test. The result of the study showed that applying chessboard technique in responding to the short story develops student’s speaking skills. Some students (60%) in the experimental group achieve good category compared to only a few students (20%) in control group.

The Mind

Science learning carried out by teachers mostly uses conventional methods and rarely uses media in the activities of their teaching and learning process. Media mind mapping in physics learning can be used to describe a lot of material and can package it to be more interesting. The aim of this research to determine the effect of mind mapping media toward the students’ concept understanding. This study used quasi-experimental research with pretest and posttest control group design. The population used was all students of class X in SMA Negeri 1 Lingsar at 2018/2019 Academic Year. The number of samples are 32 students for the experiment class and 33 students for the control class taken by purposive sampling technique. Data analysis technique used is the t-test using IBM SPSS Statistics 22. Based on the results of hypothesis testing (t test), it is known that the significance value of the posttest data (0.00) is smaller than alpha testing (0.05), so it can be stated that the mind mapping learning method influences the students' understanding of concepts.

This research is motivated by the availability of the snake and ladder game on the material of the kingdoms of Islam, Hinduism and Buddhism based on HOTS questions which have not been tested for their effectiveness on student learning outcomes. This study aims to reveal the effectiveness level of the use of snake and ladder media in the material of Islamic, Hindu and Buddhist kingdoms on student learning outcomes at SDN Ngaringan 03 Blitar. This type of research is a quasi-experimental research design with a non-equivalent control group design. The population in this study were grade 4 students at SDN Ngaringan Blitar. The research sample was taken using purposive sampling technique so that class 4A was selected as the experimental class and class 4 B as the control class. The instrument of this research is a test of learning outcomes by providing a pretest and posttest in the form of an objective test with 4 answer choices as many as 25 items taken from 40 questions that have been tested. The data analysis technique used was the N-Gain test and the two-mean similarity test (t-test). The results showed an increase in learning outcomes was better in the experimental class than in the control class. This is evidenced by the posttest mean scores of the experimental class and the control class respectively 92.12 and 73.96. This is also evidenced by the average N-Gain test for the experimental class of 0.762 with the high category and the control class of 0.294 in the low category, and supported by hypothesis testing carried out by t-test using the Independent Samples Test showing Sign 2 Tailed < 0.05, this indicates that the use of snake and ladder media is effective.

SCIENTIFIC LITERACY OF SENIOR HIGH SCHOOL STUDENTS USING ETHNOSCIENCE BASED LEARNING CHEMISTRY Scientific literacy skills are needed to understand science issues, the risks, and benefits of science, and understand the nature of science, including its relationship to culture. This study aimed to determine students' scientific literacy in using ethnoscience-based learning-chemistry. The study Method used quasi-experimental by nonequivalent control group design. The subject was grade XI-MIPA  of SMAN 1 Kendal. The data collection techniques are test instruments to know students' scientific literacy. The analysis data technique is descriptive and inferential statistical analysis (independent sample t-test and N-gain). The results showed that the ethnoscience based learning-chemistry could increase students' scientific literacy. The mean score of students' scientific literacy on experiment and control class was 72% (high category) and 65% (medium category), and count -3,551 and table -1,995. N-gain score experiment class of 0,47 (medium) and control class of 0,28 (low). Ethnoscience-based chemistry learning can be used in chemistry learning to develop students' chemical literacy skills.
