Students' thinking style is influential in learning outcomes, but teachers have not yet focused on the teaching and learning process, resulting in students having difficulties in receiving the material, especially in the study of analyzing physical concepts through graphs on the concept of kinematics. Therefore, knowing the student's thinking style especially for the physics teacher is a very important effort to achieve teaching success. This study aims to determine the students' thinking style in analyzing physical concepts through graphs on kinematics concepts. The approach used in this study is a qualitative approach with a type of descriptive research. Subjects in this study were students of class X Mipa1 and X Mipa2. Data collection instruments in this study were questionnaire, observation and documentation. The questionnaire used was in the form of a closed questionnaire adapted from the Quantum Learning book written by Bobbi DePorter and Mike Hernacki,  The results of this study indicated that the concrete sequential thinking style (S1) was 27 %, abstract sequential thinking style (S2) was 14%, random abstract (A1) was 34%, concrete random thinking style (A2) was 25%.

This study aims to develop student worksheets (SW) based on the Scientific Approach on the concept of dynamic fluids. Another objective is to determine the level of validity and response of students. The design of this study uses the R&D (Research and Development) method with the ADDIE model including the stages of analysis, design, development, implementation and evaluation. This research was conducted at the Public Middle School, Prisai Kutacane district, Southeast Aceh in class XI IPA 1, which numbered 36 people. The data collected comes from validity tests by experts, reliability, pilot tests and student responses. The data collection instruments that used were tests, questionnaires and observation sheets. The results showed that the SW validity level tested by experts was in the very good category. Based on the results of this study, it can be concluded that by applying the SW-based scientific approach, learning the dynamic fluid concept becomes more effective.

This study aims to determine the relationship between learning styles and student learning outcomes in physics subjects. The research using survey techniques and documentation with using questionnaires and documentation method for data collection. Questionnaires are used to obtain data of learning style variables, while documentation is used to obtain data of learning outcomes variables. The results of data analysis, with the product moment correlation technique, show that there is a correlation of positive and significant relationship between learning styles and student learning outcomes in physics course. In addition, the results of the study also showed that the greatest contribution of learning styles to learning outcomes was in analytic and holistic learning styles.

A Multitools instrument was developed to measure physical variables such as temperature, magnetic field, and light intensity. Multitools developed using the device of ATMEGA 8535 microcontroller that consists of three sensors: LM35 as a temperature sensor, LDR as a light sensor, and UGN3503 as magnetic field sensor. The design consisted of three stages, namely system design, hardware design, and calibration phase. The calibration test result of Multitools shows alignment level of the temperature sensor 0.9893, light sensor 0.9787 and magnetic sensor 0.9996. Measurement result displayed in physical quantities data and graph on the LCD screen of Multitools. The Multitools can be used in physics lab activity to reduce the effectiveness and train the students’ skill in understanding and interpreting the graph.
