One of the most frequently observed explanations in misconceptions is conceptual understanding. This research aimed to determine the senior high school students’ conceptual understanding of Newton’s laws in outer space. The researchers assumed that the research results would be rich in variation by elaborating the item questions based on the precise step of Digital Story Conceptual Change-Oriented as a learning medium.  The researchers researched State Senior High School 5 Yogyakarta. The participants of this study consisted of 91 students. The applied instruments were fifteen two-tier multiple-choice items. The researchers also used a non-test instrument, namely an interview sheet. The researchers found related misconceptions in Newton’s law in outer space during the research. It was found that 30% of students experienced misconceptions. The results are important for the learning process that through identification, teachers could use strategy to explain the materials.

Conceptual understanding should have serious attention due to the low score of Physics subject on national examination in Palu. The difference between learning style and jigsaw strategy is able to combine abstract conceptualization and active experiment towards the conceptual understanding for students whose learning style is converger and diverger. The research design was quasi experiment. The sample is the eleventh class of Senior High School students in Palu that are chosen using cluster random sampling (multistage), that is, 167 students. The research instrument was Kolb’s Learning Style Inventory (KLSI) of conceptual understanding test on Physics (Tes Pemahaman Konsep Fisika or TPKF). The data was analyzed by using ANOVA, with the significant level is 5%. The result shows that: (1) cooperative learning strategy of jigsaw type has more benefits than direct learning strategy in conceptual understanding on Physics, (2) student group of which learning style was converger has higher conceptual understanding than that of which learning style was diverger, (3) there are interaction influence between learning strategy and learning style towards the conceptual understanding on Physics

The C3PDR Learning Model was designed to increase student creativity in science. This study aimed to determine the effect of C3PDR learning model on improving conceptual understanding and creative thinking skills of senior high school students on sound waves topic. This study used a Quasi-Experimental Method and One-Group Pretest-Posttest Design. The sample in this study was 32 students of the eleventh-grade student in the 2017/2018 academic year from one of senior high school in Samarinda, selected by purposive sampling. Data collection used Test Techniques. The instrument used Essay Questions. Essay questions indicators to determine the understanding of physics concepts were interpreting, clarifying, comparing, summarizing, and inferring. Essay questions indicators to determine students' creative thinking skills were Asking Questions, Guessing the Causes, Guessing the Cause of an Occurrence or Even, Improving product, and Supposing. Analysis of the data used is the N-Gain analysis and paired t-test. The results showed the C3PDR Learning Model influenced the increase of conceptual understanding and the creative thinking skills of senior high school students on sound waves topic. This is indicated by 1) N-Gain of conceptual understanding was 0,76 in the high category, 2) N-Gain of creative thinking skills was 0.51 in the moderate category, 3) A significant difference between students' conceptual understanding and 4) the students' creative thinking skills before and after the C3PDR Learning Model was applied, marked with p mode <0.05.

The purpose of this study was to develop a higher order thinking skill (HOTS) based test instrument on salt hydrolysis for senior high school students. The type of research used is Research and Development (R&D) using the Plomp model which consists of three stages, namely Preliminary Research, Prototyping Stage and Assessment Phase. The test instrument was validated by 7 experts, namely 4 chemistry lecturers of FMIPA UNP, and 3 chemistry teachers using a validation questionnaire. The small group trial was carried out by 6 students and the field test was carried out by 26 students of Senior High School number 1 in Padang. The data analysis technique for content validity uses Lawshe's CVR and the construct validity uses the aiken’s formula. The results showed that the instrument developed had good characteristics in terms of logical validity with a content validity index (CVI) of 0.841 and a construct validity of 0.82. The reliability coefficient of 0.89 is very high. The analysis of discriminating power showed 16 items had very good distinguishing quality, 4 items had good distinguishing quality, 4 items had moderate distinguishing quality. The difficulty index for 88% of the questions is categorized as medium. The correlation of the item score with a significant total score was 21 items. The dictator function on all items is effective. The data obtained shows that the test instrument based on higher order thinking skills (HOTS) on salt hydrolysis material for senior high school students is valid and has good item quality.
