This research aims at investigating the effect of story mapping strategy on grade VIII students’ achievement in writing narrative text. It was conducted by using experimental research design. The Population of this research was the eighth (VIII) grade students of St. Thomas 1 Junior High School Medan. There were two classes as the sample. The first class (VIII-F) as the experimental group, while the second class (VIII-B) as the control group. The experimental group was taught by using story mapping strategy while control group was taught by using lecturing strategy. The instrument for collecting the data was writing test. The data were analyzed by using t-test formula. The analysis showed that the score of students in the experimental group by using story mapping strategy was higher than the score of students in the control group by using lecturing strategy, at the level of significance (α) 0.05 with the degree of freedom (df) 38, the t-observed was 2,818 while the t-table was 2,024. Therefore, the applying of story mapping strategy significantly affected the students’ achievement in writing narrative text.

This study aim to determine the effect of Problem Based Learning (PBL) models in mind map integration to creativity of problem solving in the environmental pollution concept of graders X. The method used is a Quasi-experimental design form Nonequivalent Control Group Design (pretest- posttest). The study population is all the students of graders X academic year 2017/2018 as many as 9 classes with the number of 360 students. The sample used was 80 students from two classes as an experimental class and a control class. Sampling was done by Cluster Random Sampling technique. Instruments used include test descriptions, questionnaires and teacher observation sheets. The results of the analysis of the test descriptions creativity in problem solving obtained results of hypothesis testing (t test) i.e. 20.5 t count > t table of 2.66 means that Ho refused and Hi accepted, it means PBL learning models in Mind Map integration effect on creativity in problems solving. This is indicated by an increase in the average score on each indicator of creativity in problem solving in which students are able to grow various ideas, enrich ideas, add or detail the details of an idea and determine the truth to solve the problems. From the analysis of questionnaire data showed an interest in learning to use the PBL modela in Mind map integration, students agreed that if the model of PBL in Mind map integration may be easier to learn about the concept of Environmental Pollution. In addition, students also agreed that if the PBL models in Mind map integration effect on creativity in problems solving. The results showed that there was a significant influence between learning using PBL models in Mind map integration those not using the learning models to creativity in problems solving in the concept of environmental pollution of graders X.

This reseacrh aims to determine the effect of the Missouri Mathematics Project learning model on the ability to think cretaively in mathematics in class VIII junior high school students in the estuary of students in the estuary of 2018/2019 academic year two-variable linearequation system (SPLDV). Jenis type of research used is true experimental design in the form of Pre-test and Post-test design. The population used was all students of class VIII of  Muara Beliti state junior high school, consistingof 295 students and as a sample was class VIII.6 with 30 students as dick classes and VIII.8 with 31 students as experimental classes. The data collection was carried out using a test technique in the form of four essay questions with a maximum score of 20. Based on the resultd of the analysis and discussion, it can be concluded that the students creative mathematical thinking ability were obtained  then  is rejected and is accepted, it means that the average score of students cerative thinking ability using the Missouri Mathematics Project learning model is more than the average score of students creative thinking ability using conventional learning, namely in the experimental class at 12.97 and in the control class at 5.47.

This research is motivated by the level of junior high school students' mathematical problem solving was still low. Based on the preliminary study which conducted by one of the schools in Batam shows the average score for mathematics was 62 for 100 scale. The purpose of this study is to obtain and investigate the improvement of students' problem-solving mastery on relations and functions material as the effect of  PAKEM model. The research method which used is pre-experiment and with one group pretest-posttest design. The subjects of this study were VIII grade students of one of the first junior school in Batam at odd semester 2015-2016 academic year, totally 32 students.  Sample of this research were taken by random sampling technique. Students’ problem solving mastery was measured by using problem-solving test, whereas the students’ problem-solving mastery improvement between before and after the concept of effect size implementation was calculated to find the effect size of applying the PAKEM model. The result showed that the effect size of applying the PAKEM model on improving problem solving mastery is 3.3, it means, the PAKEM model implementation on improving problem-solving mastery on function has a strong influence. It can be concluded that the PAKEM model implementation can improve problem solving mastery.
