This study aims to develop interactive multimedia learning media on science subjects using Adobe Flash as a learning media for SD IVC classes. This development is in the form of learning media products in an interactive CD. The method used in this study uses the Research and Development (R & D) method with a 4D model that has 4 stages of development, namely define, design, development, and desseminate. The results of the validation test show that interactive multimedia learning media in science subjects are declared good with the results of validation by media experts 3.75 with very valid categories, expert material 3.5 with very valid categories, and by 3.54 users in good categories. Based on the N-Gain of 0.60 with the medium category and it can be said that the effectiveness of interactive multimedia as a learning media is classified as effective. Based on these results, it can be concluded that the development of interactive multimedia on science subjects using adobe flash as an instructional media for SD IVC is declared feasible and effective to be used in the learning and teaching process.

This research was qualitative research with descriptive method. Subject was student teachers who took Fundamental Science 1. Based on validity analysis of item on 1 % significance level, there were 16 valid items, 26 valid ietms for 5 % significance level, and 14 invalid items. Then, analysis of distinguishing items, the item number 20 was very worst, 15 items were poor, other 15 item were fair and the other items were good. Meanwhile, analysis of level of difficulty, 17 item were very easy, 9 items were easy, 11 items were moderate, an item was difficult, and the others were very difficult. Analysis for whole items, there were only 21 items that were ready to be used, 5 items were needed to be revised, and the others could not be used in a testKey words : Konsep Dasar IPA 1, validity, distinguishing items, level of difficulity

This study aims to improve the mental model of prospective primary school teacher related to the concept of boiling through the implementation of the conceptual development-oriented instruction (CDOI) model assisted by multimode visualization. This research was conducted using the pre-experimental method with the design of one group pretest-posttest. The subjects of the study were 36 the prospective primary school teachers, consisting of 20 female and 16 males. The research location is one of the universities in Riau province. The instrument used for collecting data is the conceptual understanding level test related to the concept of boiling in the form of open-ended that cover three parts of the question, which has previously been validated and tested for its reliability. The results of this study indicate that the implementation of the CDOI model assisted by multimode visualization has high effectiveness in facilitating the achievement of the scientific mental model, and no gender bias on achieving scientific mental models by the prospective primary school teacher.

The purpose of this research is that to create even distribution and understanding about life areaeducation to primary school students that will obtain students’ attitudes in doing actionsappropriating to the concept of life area education and create an alternative the development of lifearea education in Pekanbaru based on national curriculum or local curriculum. So that it can givecontribution to the curriculum in in real on the framework of life area education. The data used in thisresearch were primary and secondary data. Primary data sources from survey (direct observation) atschool, interview with stakeholder related to Head of Education Department, headmasters, andteachers. Primary data were also obtained by giving qutionare to headmasters, teachers, and studentsrelated to cognitive, affective, and psychomotor about life area education. Secondary data wereobtained from school condition like document of PLH activities at school and also stakeholders. Basedon the data of school curriculum analysis to life area education that it can be integrated into fivesubjects that are religion, civics, science and technology, art, and physic education. Based oneducation stakeholder analysis that they supported the life area education to put into local curriculumand to be implemented into daily life at school. Based on analysis data on knowledge and attitudesthan primary school students fully understood about life area education, and they have done to careabout school area.Key Words: curriculum analyze, life area education

Many students and even teachers still cannot recognize the relevance of the model to build physical knowledge. The study of mental representations built by students in their interactions with the world, phenomena and artifacts, is an important line of research in science education. Therefore, it is not surprising that analogies play an important role in science education, because the construction of students in mental models of abstract phenomena must be rooted in some existing or previous experiences, to interpret more complex ideas. The purpose of this study is to investigate mental models elementary school students against the phenomenon of day and night. This research is quantitative descriptive. The research subjects were 20 students in grade six. The results showed that 20% of students had a low mental model (LMM), 45% of students had a moderate mental model (MMM), and 35% of students had a high mental model (HMM). Based on the results of the study it can be said that, (1) 20% of students cannot explain the concepts scientifically and students' understanding is at the level of symbolic representation. (2) 45% of students cannot explain the causes of a phenomenon, student understanding is at the level of macrocospic representation, (3) and 35% of students have concepts with understanding based on real-life observations with scientific concepts learned at school and students' understanding is at the level of representation of microcosms.
