Abstract

This study aims to determine whether there is a significant difference in understanding the concept and motivation of chemistry learning among students of class XI MIPA SMA Negeri 1 Banguntapan in 2014/2015 academic year that attended the constructivistic approach learning procces with and without the integration of macroscopic dimensions, symbolic dimensions, and submicroscopic dimensions. The initial knowledge of chemistry is statistically controlled. This study was an experimental research with one factor, two sample, and one covariable research design and one factor two sample research design. The population of this study were 128 students of Class XI MIPA SMA Negeri 1 Banguntapan that were divided into 4 classes. The sample in this study were 64 students taken by purposive sampling and divided into two classes, namely experiment class (A1) with 32 samples and control class (A2) with 32 samples. The data obtained in this study were early chemistry knowledge data, early and final chemistry study motivation, and student’s understanding data of chemistry concept. The hypothesis was analyzed with anakova (covariance analysis) and t-test. The results showed that there were no significant differences in understanding the concept and motivation of chemistry learning at class XI MIPA in SMA Negeri 1 Banguntapan that attended the learning procces with constructivistic approach based on the integration of macroscopic dimensions, symbolic dimensions, and dimensions submicroscopic and who follow the learning with constructivist approach without macroscopic dimension integration, symbolic dimensions, and submicroscopic dimensions. The implementation of constructivist approach based on dimension integration in chemistry is not effective in understanding the concept and motivation of chemistry learning in class XI MIPA of SMA Negeri 1 Banguntapan at 2014/2015 academic year.

Abstract

The application of the revised Bloom's taxonomy in the development of chemistry problems in the domain of knowledge is still difficult for some chemistry teachers. This paper is a practical study of the preparation of learning objectives and the development of chemical items by applying the revised Bloom's taxonomy which includes three domains, namely knowledge (cognitive), attitude (affective), and skills (psychomotor). This paper is focused on the preparation of learning objectives and the development of chemistry items for the assessment of the domain of knowledge which includes the levels of remembering, understanding, applying, analyzing, evaluating, and creating. The six cognitive processes are sequential from the lowest cognitive processes to the highest cognitive processes called C1-C6 cognition processes. The methodology in this paper consists of three steps, namely examining the meaning of each level of cognition in the revised Bloom taxonomy, developing learning objectives that are in accordance with the cognitive level being studied and continuing with the arrangement of the problem items in chemistry subjects. The strengths of this study are very helpful for chemistry teachers in developing learning objectives and chemistry questions in the domain of knowledge based on the revised Bloom taxonomy, because this study is equipped with descriptions of each cognitive process, examples of learning objectives and appropriate question items. Examples of questions given in this paper are multiple choice types and essay tests, because each type of question has its advantages. The result of this study is that the application of the revised Bloom's taxonomy to the development of chemical problems requires an understanding of each level of the cognitive level in the revised Bloom's taxonomy, as the basis for developing learning objectives and the appropriate problem questions.
