The City

This research is motivated by the low mathematical communication skills of junior high school students in the city of Bandung Regency. This study aims to determine the comparison of the mathematical communication skills of junior high school students in the city of Bandung regency between the learning usingmodels Think Talk Write. The method used in this study is a quasi-experimental method with a pretest-posttest control group design involving two groups and randomly selected classes, at the beginning and end of the study the two classes were given a test. The population in this study were junior high school students in the city of Bandung Regency, while the sample consisted of two randomly selected classes. Obtained class VII A (experimental class) given themodel Think Talk Write and class VII B (control class) is given a scientific approach. The instrument used was a 5-item mathematical communication ability description test, then theability scores mathematical communication students'were analyzed with descriptive and inferential statistics using the help of SPSS 21 software.

Materials Used

This study aims to analyse textbooks used by students based on the scientific approach as the realization of learning objectives using the 2013 curriculum. This study did several things: first, an investigation of the teaching materials used by students based on the scientific approach, second studied the suitability of the content of textbooks used by students with the syllabus in the 2013 curriculum, thirdly investigating the contribution of textbooks used to higher-order thinking skills. Research method used is mixed methods namely descriptive method and survey study at Islamic Junior High School in Medan. There are 3 textbooks that will be analysed, the textbooks from three different publishers which used by the school. The total number of students who participated in this study were 201 students. Where students who participated in the study were selected based on purposive random sampling through certain considerations, the students come from Islamic Junior High School An Nizam, Islamic Junior High School Ulun Nuha, and Islamic Junior High School Al Fityan, the condition and character of schools are almost same, so is expected the homogeneous sample. The results obtained are: (1) From the three books, the results of conformity assessment with the syllabus in book A are 65%, book B is 80%, and book C 40%; (2) The evaluation results of the textbooks by using the scientific steps find that book A obtained a score of 53 in the low category, book B got a score of 58 in the low category, and book C got a score of 55 also in the low category; 3) The results of the assessment of HOTS ability of students from each school that use books A, B, and C are on the average low category.

One of the goals of learning mathematics is students can solve the problems. PISA problems can be used to bring up the problem solving activities. Keirsey's personality type is chosen because it offers possibility on differences in each personality type. It is based on the characteristics in taking and processing information, making decisions, and patterning the implementation of their tasks. The aim of this research is describing the profile of junior high school students about PISA problem solving based on personality type. This research is a qualitative descriptive research using test and interview methods. The subjects consist of four students, which are guardian, artisan, rational, and idealist. The results showed that on the understanding the problem stage, all students read the questions and were capable in identifying the information in the question. Then represented what is known and unknown. At the devising a plan stage, the four subjects were able to link the information that was known with prior knowledge to make a plan. At the carrying out the plan stage, the four subjects used the appropriate knowledge to implement the settlement plan that has been made. At the looking back stage, all the students examine their solutions.Keywords: problem solving, PISA questions, personality type

Based on observation result, study documentation of interview and questionnaire that was given to the students, problems found, the teaching skills of junior high school science teachersat STOof Ogan Ilir regency inapplying scientific approach had been still low, this research was conducted with the aim to investigate whether STO activity ofOgan Ilir regency could improve the teaching skills of junior high school science teachers in Ogan Ilir regency in implementing the scientific approach. The methodology used in this research is action research which was conducted for three cycles. Each cycle consists of, planning, execution, observation, evaluation and reflection. The result showed that the teaching skill of junior high school science teachers in applying scientific approachhad improved significantly from the first cycle to the second cycle, and from the second cycle to the third cycle. Increasing of teaching skills of science teacher in applying scientific approach was the effect of STO activity.

Character building becomes an essential part in the science learning process to prepare the students as the next generations of our nations. This study aims to develop a valid, practical, and effective learning model combined with indigenous science content for junior high school students in developing local wisdom-based characters and high-order thinking skills. This research is a a research and development (R & D) approach with the Borg and Gall model involving 36 junior high school science teachers (72 teachers). The research instrument were a character questionnaire as well as a test of problem-solving, critical and creative thinking tests, along with an assessment rubric to measure the depth of students' cognitive abilities. From the results of the learning model trial, it was found that there are eight characters based on Balinese local wisdom that can be developed in science learning for junior high school students namely religious, being honest (satyam), tolerance (tat twam asi), responsible (sesana/swadharma), curious, jengah, hardworking and generous, caring and friendly with nature. Conceptually, the core stages of the junior high school science learning model to develop Balinese local wisdom based characters include: initial exploration, investigation from various perspectives, elaboration, and confirmation and reinforcement. The stages in the science learning model that develop characters based on local wisdom provide opportunities for teachers to improve students' cognitive abilities, especially in the realm of higher-order thinking skills.

Scientific Approach

The purpose of this study was to determine the increase in creative thinking skills of junior high school students who use learning by using the problem posing approach and the scientific approach to classroom learning, especially in mathematics. Quasi experiment is this type of research with the control group pre test and post test design. The research was conducted at one of the junior high schools in Cimahi City. As many as 62 students of class VII being sampled in this study consisted of 30 students in the experimental class with problem posing learning and 32 students in the control class with scientific learning. The testing in this study uses IBM SPSS version 22 software. The conclusions from the results of this study are 1) Increasing the ability of mathematical creative thinking by using a problem posing approach better than the scientific approach, 2) A problem posing approach if it is well planned for effectiveness when learning takes place, and 3) Students who are inaccurate in solving the problem of the ability to think creatively because they do not understand the problems asked in the questions. This can be seen from several responses of students who are incomplete in giving responses
