Abstract
One of the goals of learning science based on the 2013 curriculum is to develop students- reasoning abilities and and lead them to be independent. One form of reasoning abilities is an abductive reasoning which is a process of the best hypothesis that begins with observing facts, proposing hypotheses or making the most reasonable answers. When someone does this process, he is, basically, on the early stages of abductive inquiry process. When students formulate hypotheses, it is possible to formulate the different hypotheses between one student and the other students. This study aims to identify the characteristics of the types of students- abductive in science by implementing the abductive inquiry model (AIM) integrated a connected type to global warming material. This is a qualitative research, the instruments used are audio recordings of student and teacher dialogues during learning activity and observation sheets to captue student abduction type adopted from Shurcz. The subjects in this study were 30 VII grade students in one of the Middle Schools in Lembang who were selected using a purposive sampling. Students are divided into 6 groups and discussed different sub- topics related to global warming material. The results showed that the abductive type of students in science learning using integrated MIA connected types varied among groups; abductive theoretical, existential abductive models and abductive laws or rules. The implications of abductive inquiry learning in science and relevant research are highly recommended with different material.

Abstract
The purpose of this study is to obtain information about the conception of pre-service chemistry teachers related to chemical contents in the context of conductive glass. Descriptive research method was chosen as the method in this study and the analysis was carried out quantitatively and qualitatively with 27 participants in the fourth semester at one of the universities in Bandar Lampung. The instrument used were 11 essay questions covered in 7 different discourses. The results obtained will be used to make didactic design in learning in the context of conductive glass. Based on student answers, it is known that 70,3 % or 19 students still have a low understanding of the concepts of resistivity and semiconductor. The low level of understanding shows that there are still many students who do not understand the chemical contents and become the basic for researcher in making didactic design to teach chemical contents in the context of conductive glass.

Abstract
Argumentation plays an important role in the development of science which is not just finding and presenting facts, but building arguments and considering them, and debating various explanations about phenomena. The research aimed to capture the consistency of argument by students on socioscientific issues of cloning. Students have chosen purposively with the subject of 170 high school students from three high schools in Bandung City, West Java, Indonesia. This research uses a case study approach with a descriptive analysis to analyze student test results of argumentation. The consistency of argument consists of claims and reasons itself. The result shows the pattern of agreeing and disagree about cloning in 3 topics; 1) human, 2) animal for Qurban purposes, 3) extinct animals. The higher consistency showed disagree in topics 1&2 about 56,47% and consistency of reason for each topic are 1)religion 40%, 2) religion 57,6% and 3) science 83,5%. Then, the consistency of agreeing for all topics is 2,35% and disagree is 14,71%. This provides that, consistency in argumentation between topics of cloning is based on the context of phenomena, which is greatly influenced by science, religion, and social norms. It needs to be implemented to improved students argumentation in schools.

Abstract
Two-tier multiple choice instrument is an instrument consisting of two tiers, the first tier is the choice of the answer from a question and the second tier is the choices of reason for an answer at the first level. The two-tier instrument can be used to measure students-science process skill. This study aims to analyze contents validity two-tier instument multiple choice to measure students- thinking skills in a statistics fluid. The method used in this research is a descriptive analyze a method for content validation based on Formula Aikens. Data of content validation was obtained from 8 experts, consisting of 4 lecturers who had doctorates and 4 high school physics teacher of the senior high school in Madiun. Based on the results and discussion, can be concluded that 14 item question of multiple choices instrument to measure students science process skills in heat and temperature are declared valid based on Aiken Validity.

Abstract
This study aims to examine the external factors of a laboratory as the core of the learning process. Two questions arise and become the focus of the study as follows: (1) How is the management of physics learning media laboratory of Physics Education Study Program in Universitas Negeri Jakarta and (2) How vast is the contribution of laboratory management to the learning process of physics education courses. In this study, a descriptive quantitative and qualitative instructional design is utilized. The laboratory standard referred to the Indonesian Education minister-s regulation, Likert scale to see the management of the laboratory, and descriptive analysis to see the contribution of laboratory management with integrated courses of physics education courses. The research findings show that the physics learning media laboratory has met the government standard with a value of 4.16 (very good) for it-s management. As for the contribution, the laboratory has contributed approximately 50% of physics education courses which are integrated with the laboratory. These research outcomes hopefully can be used by teachers and laboratories to enhance its management and contribution to university courses and other education facilities.
