Abstract

Problems in learning chemistry in MAN Cendekia Jambi are the students’ grade still below the minimum completeness criteria, one way direction learning  from the teacher to the students and the lack of students participation.  The study aims to determine the effect of the use of interactive multimedia, non interactive multimedia, and students learning interest on chemistry competence of MAN Jambi students. This study uses quasi-experimental study with factorial design (3x2). The results show that: 1) there are differences in the chemistry competence of students using interactive multimedia, non-interactive multimedia, and white board media, 2) there is no difference in the chemical competence between students of high interest learning and low interest learning, and 3) there is no interaction between media and student learning interests.

Abstract

Local content mediated PBL model is a facility to make students active and also as a media to deliver massages in learning process that make an independent student. By knowing student?s learning style, the teacher can implement the suitable learning model. So it can increase the learning result. Based on the result of this research we found the effect of learning model of local content mediated PBL to the learning result. The learning result is different between students who have kinesthetic learning style and student who have auditory learning style. Given the existence interaction between learning models of local content mediated PBL and learning style to the student?s learning result it can be concluded that by knowing student?s learning style, the teacher can implement the appropriate lesson model that ultimately could increase students? learning result.

Abstract

This development research is conducted at SMKN 3 Jambi, the purpose is to develop contextual based chemistry learning material for Xth grade Technological Vocational High School (SMK) with content and contex representative enough for SMKN 3 students. The model used in this research development is the type 1 development mode from Richey by adopting the development model of Dick & Carey. This development research is conducted in four important steps, they are analysis, design, development, and evaluation. The data are collected using openended questionaire. The subjects are students from class X TPM1, X TKR2, and X TKR3. These samples are taken randomly but remain to represent each student ability level, high, medium and very low. The research result shows the positif respond towards the developed  product. Based on the  collected and analyzed data, it can be concluded that the developed product is interesting, simple and easy to understand, can increase student?s positif characters such as interest, participation, responsibility, and relate to student selected skill.

Abstract

The objective of the research is to develop a class xi chemistry instructional medium the topic of acid-base titration with the orientation of improving the students skill of scientific process in the laboratory. The research is a developmental research and the model used is ADDIE, which stand for Analyze, Design, Develop, Implement and Evaluate. Having been validated by some assessors and teachers, the medium developed proves adequate and can be implemented among class xi high school students. The result of the reaserch show that the student respon well to the implementation of the medium. The medium can be  used by student with various capabilities : however, among weak students  teacher’s guidance is needed.

Abstract

The problems encountered in learning biology in SMAN 13 Tebo is the low result in learning biology, and the class average (57 and 58) of minimal completeness (KKM). The causes include the lesson still done traditionally, the class still focus on the teacher as main source of knowledge. Objective of this study to determine the influence of the biology of learning outcomes: the student taught by using media (powerpoint) contextual and those taught by using traditional approach, student of high scientific attitude and low scientific attitude, and presence or absence of interactions between media (powerpoint) contextual approach and scientific attitude toward the biology learning result. This research is an experiment research with factorial design 2x2. Methods research design used in this study is a quasi experimental pratest and postest. The data are analyzed using two way ANOVA. Results of this research indicate that there is a influence in learning result between student taught by using media (powerpoint) contextual and those taught by using traditional approach, there is no influence in learning result between student of high scientific attitude and low scientific attitude, and there is no interaction between media (powerpoint) contextual approach and scientific attitude toward the biology learning result.

Abstract

Macroscopic and symbolic representation used in chemistry instruction to represent chemical changes are unable to visualize chemical changes that occur at atomic and molecular level. The purpose of this study is to develop interactive multimedia to enhance of macroscopic and symbolic representation by providing submicroscopic representation of electrolyte and non electrolyte solutions. The media was developed by using Adobe Flash and validated by experts and used for trial in small and large groups of students before the final product was being used in a real classroom teaching based on Computer Model approach. Providing submicroscopic representation attracts student’s attentions and retention in studying the teaching materials and potentially improves student’s understanding and achievement.
