Abstract

This study is motivated by the difficulty of leaners to understanding the concept of chemical bonding as a whole. Learning that does not represent submicroscopic level causes leaners difficulty to resolving submicroscopic based chemistry questions. This study aims to describe leaner’s ability in represent the concept of chemical bonding at the submicroscopic level. A qualitative descriptive method used in this study. The participants of the study were 30 leaners XI grade of SMA Negeri 1 Meulaboh. The submicroscopic based test instrument was employed in the study to collect the data. The result of study showed that the leaner’s ability of submicroscopic representation about chemical bonding as a whole falls into the category of enough with a percentage of 58.78%.  The average leaners score is 59.32 included in the criteria of sufficient understanding. Generally, leaners were not able to solve the submicroscopic based questions about chemical bonding as expected. The low ability of submicroscopic representation is due to leaners are not used to describing the ions, electrons, and molecular shapes submicroscopically, understanding of chemical bonding concept that are not yet intact, lack of interest and attention of leaners in receiving concept in the learning process.

Abstract

This research aims to reveal the creativity of the Inpres elementary school teachers in learning science and to build a specific theory based on the components of teachers’ creativity in selecting and using the media in learning science, factors that support teachers' creativity in developing materials, developing methods, and the steps conducted by the school in developing the teachers’ creativity. This research uses a qualitative phenomenologic interpretive by applying naturalistic model of Guba. The determination of research information was done purposively. Subjects of the research were teachers who taught science at grades IV, V, and VI. Data were collected through observation, interviews and documentation analysis, and were analyzed using the Bogdan model analysis. The data validation was obtained through perseverance of observation and triangulation. The triangulation was done with respect of sources, methods, and theory. Results of this research is in the form of a specific theory that the principal’s idea to improve the academic quality could encourage the teachers’ creativity in the science teaching and learning process at the public elementary school “Inpres Sido". This is in line with the social theory, including the theory of learning development within an institution, namely, that the social institutional changes occurred by developing insight or knowledge.

Abstract

Obeservation results indicated that students have difficulty of explaining chemical phenomena in league level representations (macroscopic, symbolic, and submicroscopic levels). The aim of the study was to obtain the information related to the influence of the use of teaching materials based on multi-level representation of the ability to solve the problem of solution materials of MAN students in Pidie Jaya. The teaching material contained of macroscopic, symbolic, and submicroscopic levels. Type this of research was quasi experiment which was tested in MAN Pidie Jaya. The study was conducted for four months through two stages namely: (1) observasion, (2) implementation. Implementation was carried out by using one-group pre-test design and post-test design. Instruments used consist of; observation sheets, note sheets of learning constraints, assessment and problem solving and representation sheets, and student response questionnaires. The data were obtained them analyzed descriptively. The results showed: (1) the ability chemical problem solving in MAN Ulim Pidie Jaya was increased from the average of 43 pre-test to 73 in post-test result this means that the teaching materials based on multi level representation used can train the ability to solve problem the solution, (2) the profile of students' ability movement during the learning process using teaching materials based on multi level representation increased at one to three meetings, this happened because the fourth meeting material characteristic was more complex, (3) based on student response to the using of teaching materials based on multi level representation was very helpful in training solve chemical problems of solution.
