The ability to solve problems is a skill that students need to have in dealing with various problems in life. This study aims to determine the effect of problem based learning models; cognitive styles and interaction between both factors on science learning outcomes of students in class VII of MTs 2 Tanjung Jabung Timur in academic year 2015/2016. This research was conducted with a quasi-experimental research method by applying a 2 × 2 factorial design. The study sample consisted of an experimental class of 30 students and a control class of 29 students. Data collection was conducted using two types of instruments, namely the Group Embedded Figures Test (GEFT) to measure students cognitive styles and students' learning outcomes test in essay forms. The Problem Based Learning model affect the learning outcomes, there is significant difference in science learning outcomes between students who have Cognitive field dependent (FD) style that is taught by the Problem Based Learning model and students who have Cognitive FD style that is taught by conventional learning models. The results show that the value of the experimental class post-test is higher than that of the control class. In short, the experimental class with the application of the Problem Based Learning model in the learning process provides higher learning outcomes than that of the conventional models.

Students have their own personality types which will ultimately affect their learning skills. This study aims to describe the critical thinking process of cholerist type students in solving mathematical problems. This type of research is a qualitative-descriptive study. The subjects of the study were students of SMK 5 Muaro Jambi who had participated in the district mathematics olympiad. The instruments used were personality test sheets, problem solving sheets and interview guidelines. The researcher directly observed the process of solving mathematical problems performed by the research subject. The researcher analyzed the results of the students' work in formulating questions, solving problems, and interviewing research subjects. The interview data was analyzed by means of data reduction, data exposure/categorization and subsequent conclusions. The results of this study indicate that during the problem solving process research subjects can solve problems casually, confidently and correctly. From the results of solving problems I and II it can be seen that the research subjects make decisions very quickly, directly and solve them with different steps according to the situation and the results of their thoughts on the problems faced. It can be concluded that the research subjects were able to solve the problem critically.

Laboratory is a facility to support the activities of learning in school, every high school should has a good laboratory management to support biology learning activities. This study aimed to analyze the biology laboratory management that has been done by the senior high school laboratory manager in the district of Batanghari in Jambi province. The research is descriptive study; the research subjects are research laboratory heads and teachers of biology. The laboratory management analysis includes aspects of planning, organizing, structuring, administering, and securing. In this study the data obtained from observation, questionnaire, interview, and documentation. The obtained data were analyzed descriptively. Overall, two schools are categorized as excellence (SMAN A; 89.2 % and SMAN B; 87.9%); two schools are in very good category (SMAN C; 78.2% and SMAN D; 78.0%); and two schools are in the last category (enough category) includes SMAN E (66.8%) and SMAN F (61.5%). Moreover some aspect of biology laboratory management in senior high schools are not well managed yet. Based on the results it is suggested that laboratory managers should improve the laboratory facilities as well as their competencies in managing the laboratory. Moreover, senior high schools should employ laboratory technicians and laboran to assist the task of laboratory heads and teachers to produce a more effective laboratory management

Pengembangan Lembar Kerja Peserta Didik (LKPD) Berbasis Kontekstual Pada Materi Ekosistem Kelas VII SMPN Tanjung Jabung Timur: The Development of Contextual Based Student Worksheet (LKPD) in the Material of Class VII Ecosystem, SMP Tanjung Jabung Timur Yanto Sugiyanto; M.

Innovative and fun learning can be realized through various ways, one of which is by using relevant and interesting media. This study aims to produce a student learning worksheet based on the Contextual Teaching and Learning (CTL) approach on the ecosystem material for class VII, and to determine the effectiveness of the use of the student worksheet. This is a research and development research using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The development process data was collected using a validation questionnaire of design experts, material experts, teacher and student questionnaires and student learning outcomes data after using the worksheet. The results of the assessment by material experts obtained average value 3.11 (good category) while the assessment by media experts obtained average value 3.30 (very good category). Assessment by students gets average value 90.33 (very well category), the assessment by teacher gets average value 10.82 (very good categories). The use of the developed student worksheet in the learning process shows a significant increase in the average learning outcomes from 52.31 to 72.69 (increase 20.38). The produced student learning worksheet is declared appropriate for use in learning.

Traditional knowledge held by society contains character values and scientific concepts, but such knowledge is frequently ignored. This study aims to develop Student Activity Sheets on plant taxonomy based on ethnoscience for high school, and analyze the response of teachers and students to the products developed. The model used in this study follows the ADDIE stages. The instrument used is a response questionnaire given to teachers and students. Product feasibility was analyzed through the results of material expert validation and design experts. The result of the study is in the form of student worksheet based on ethnoscience and character values for plant taxonomy material. The results of product validation obtained a score of 74 ("very valid") for the material aspects while the design validation obtained a score of 46 ("valid"). The results of the small group and large group trials obtained percentages of 87,0% and 89,0% respectively; both were in the excellent category. The teacher's response obtained an average score of 44 which was also in the excellent category. Overall student worksheets based on ethnics and character values in material plant taxonomy for high school students is feasible to be used in plant taxonomy learning in schools.
