This research is intended to know the effectiveness of worksheet based on an inquiry to grow the higher order thinking on temperature and heat. The design which is used in this research is one group pretest-posttest design. The data analysis technique was performed by using the N-gain test and one sample t-test. The result of this research shows that Student Worksheet is effective as learning innovation based on high level thinking the skill that is analyzing (C4) and creating (C6) into a high category with N-gain 0,70 while to evaluate obtained N-gain 0,72 (height). Student Worksheet effectiveness based on high-level thinking skill proved influential in cultivating high-level thinking skills based on the results obtained using effect size of 0.6 to analyze and evaluate while to create 0.7.Penelitian ini bertujuan untuk mengetahui keefektifan LKS berbasis inkuiri untuk menumbuhkan keterampilan berpikir tingkat tinggi pada materi suhu dan kalor.

Abstract. This study aims to develop electronic module design based on Learning Content Development System (LCDS) to foster students' multi representation skills in physics subject material. This study uses research and development method to the product design. This study involves 90 students and 6 physics teachers who were randomly chosen from 3 different Senior High Schools in Lampung Province. The data were collected by using questionnaires and analyzed by using quantitative descriptive method. Based on the data, 95% of the students only use one form of representation in solving physics problems. Representation which is tend to be used by students is symbolic representation. Students are considered to understand the concept of physics if they are able to change from one form to the other forms of representation. Product design of LCDS-based electronic module presents text, image, symbolic, video, and animation representation.Key words: electronic module, learning content development system, multi representation IntroductionFacing the rapid development of the 21 st century era, educators and educational institutions are required to deliver students who have 21 st century competence. Based on [1], there are ten types of 21 st century competence, some of them are critical thinking, problem solving skill, decision making skill, effective communication skill, multi representation skills, information literacy, and ICT (Information and Communication Technology) literacy. In order to develop students' information literacy and ICT literacy competence, ICT integration in the learning process is needed. ICT integration, including internet, as a learning tool can support the increasing of students' information literacy and ICT literacy competence effectively [2]. Currently, ICT has been widely applied in the learning process. Many learning media are made by utilizing information and communication technologies such as computers. Even laboratory practice activities can now be done by utilizing ICT. Information and communication technology certainly has a large effect to overcome the limitations in the learning media.Students' difficulties in understanding the lessons are influenced by some factors: (1) students only rely on one supporting book and it is the student worksheet. It shows that in terms of learning material,
The purpose of this research is to know the difference of mathematical representation skill, the result of science learning and its influence on problem-based learning and discovery learning model. The population of this study was 16 students of PGSD FKIP University of Lampung. Among 534 students, there were two experimental classes consisting of 35 students and each was determined through cluster random sampling. The data on mathematical representation skills and learning outcomes of science were obtained through a description test, five questions for assessing mathematical representation skills, and ten questions for assessing science learning outcomes. From the instruments that had been tested to 30 respondents, it was obtained a valid and reliable instrument with a score of 0.505 for mathematical representation skills, and 0.832 for learning outcomes. Furthermore, the data were analyzed by using normality test, homogeneity test, independent sample t-test, correlation test, and simple linear regression test. The results showed that there was no difference in the result of mathematical representation skill and science learning outcomes, between the problem-based learning model and real discovery. But there is a positive and significant linear influence between the mathematical representation skill and the learning outcomes of science, through a problem-based learning model of discovery.
The purpose of this study is to findout the effectiveness of module with inquiry model to improve the student’s scientific process skill to wards heat material. The research design used was quasi-experimental design in the form of nonequivalent pretest-postest control group design. Based on the results of the effectiveness test, it was known that the value of n-gain experimental class was 0.62. It was greater than the control class with the score was 0.40. Student's scientificprocess skills also increased for each indicator. Based on the research that has been done, it can be concluded that the module by using inquiry modelwasthe effectiveto improve the student's scientific process skills. Tujuan dari penelitian ini adalah untuk mengetahui efektivitas modul untuk menumbuhkan keterampilan proses sains siswa. Desain penelitian yang digunakan adalah quasi experimental design dalam bentuk nonequivalent pretes-postes control group design. Berdasarkan hasil uji efektivitas, maka diketahui bahwa nilai n-gain kelas eksperimen (0,62) > kelas kontrol (0,40). Keterampilan proses sains siswa mengalami peningkatan untuk setiap indikator. Berdasarkan penelitian yang telah dilakukan, dapat disimpulkan bahwa modul dengan model inkuiri telah efektif dalam menumbuhkan keterampilan proses sains siswa.
