Abstract
Abstract This research is motivated by the low interest in reading students towards concepts that are considered difficult because they are abstract, especially on the concept of hydrocarbons, so that the media needed can help students to understand the context with the help of simple, efficient and interesting tools. This study aims to describe the stages of making AR technology-based learning media on the concept of hydrocarbons, increasing students interest in reading, and analyzing the feasibility of the learning media. Research and development has produced products in the form of AR technology-based learning media on the concept of hydrocarbons. The stages of research are carried out by analyzing hydrocarbon concept development, design, validation, feasibility testing, and limited testing. Due diligence and limited testing are conducted to obtain feedback for improvement and assessment of learning aspects, conceptual substance, visual communication, and software engineering, as well as the feasibility of their use. In general, the test results obtained by the calculation of feasibility = 0.8-1.0 and the reading interest questionnaire indicate that students-reading interest has increased. This shows that the presentation of learning media is appropriate to be used as a learning resource for students to increase students-reading interest in learning.

The dissemination involves 29 students taking internship program from 2013 to 2014, at several schools in Bandung. The results show that scientific project-based worksheets, with N-gain average of between 0.55-0.82 is categorized as medium and high, and significantly different at significance level α = 0.05. It means the use of the worksheets significantly improves learners- concept understanding as a whole. Feedbacks gained also suggest that the developed worksheet models have positive effects on the students attitude towards science, with the average score from 81.33 to 88.37. The rate for psychomotor aspect, with its mean value 80.73-91.67 has proven to be effective to encourage students to be more active during lab activities.

Abstract
This study aim to know the effect of active learning model Guided Note Taking (GNT) on student-s critical thinking ability for work and energy subject in senior high school. This study was held in Senior High School 77 on March 2019. This research used a quasi experimental method with a nonrandomized pretest-posttest design. The sample used purposive sampling, so the experimental class and control class were obtained. Before the research started, a pretest was given to know both classes have the same condition. The results showed that the pretest average value of experimental class was 43,25 while the control class was 42,75. This research instrument was posttest essay-s type with 10 questions. Prerequirement test used normality test by Chi-quadrate formula, because X2hitung≤X2table (4,58≤11,070) on experimental class, and X2hitung≤X2table (4,72≤11,070) on control class, so data was normally distributed. Homogenity test on α=5% and n=36 got that Fhitung≤Ftable (1,427≤1,757), so data was homogen. Based on hypothesis test by t-test with α=0,05 and dk=n1+n2-2, got that thitung>ttable (4,278>1,667), So, H0 is rejected and Ha is accepted. Then, the conclusion is student-s critical thinking ability who learn with Guided Note Taking model higher than direct instruction model and also Guided Note Taking has an effect on student-s critical thinking ability.

Abstract
This study aims to determine the effect of the cooperative learning model Think Pair Share assited by animation media on learning outcomes of physics in high school. This study was held in SMA Negeri 30 Jakarta. This study used a quasi experimental method with a nonrandomized pretest posttest design. The research sample was taken using purposive sampling, so that the experimental class and control class were obtained. The experimental class uses a cooperative learning model Think Pair Share assited by animation media, while the control class uses direct instruction. The results showed that the learning outcomes of experimental class student were higher than the learning outcomes of control class students. It can be seen from the posttest average value of experimental class = 83,17 and the control class = 78,75. This posttest resuls were tested using the t-test, resulting tcount = 5,429 and ttable = 1,667. Based on the results of t-test, the value of tcount > ttable, means H0 is rejected and Ha is accepted. Then, the conclusion is cooperative learning model Think Pair Share assited by animation media has an effect on learning outcomes of physics in high school.
