Abstract

This study aims to explain the relationship between critical thinking skills (CTS) and mastery of concepts and the relationship between meta-cognition and mastery of concepts in several chemistry learning models in senior high school. The learning models used in this study are discovery learning and direct instruction. This research was carried out for 8 months at Senior High School Makassar city and Maros Regency by involving two graduate program students in the S2 chemistry education study program. The subject and object of this study were XI MIA SMA class students for buffer solution chemistry. The research tools and instruments used in this learning study are instructional tools and test instruments of critical thinking skills and mastery tests of concepts and instruments of the Meta-cognitive Awareness Inventory. The methods used are 1) observation, 2) preparation of teaching tools, 3) preparation of assessment instruments,4) implementation of learning in schools, 5) filling questionnaires, CTS tests, and mastery of concept tests. Data were analyzed inferentially and descriptively. The results of data analysis show that (1) there is a relationship between critical thinking skills and mastery of chemistry concepts for students both learned by investigation-based learning models (discovery learning) or those taught with direct instruction model, (2) there is no relationship between meta-cognition and mastery students 'chemistry concepts both learned by investigation-based learning models (discovery learning) as well as those taught with direct instruction  models, and (3) critical thinking skills and mastery of chemistry’s concepts that learned by investigation-based learning models are higher than those taught by models direct instruction.

Abstract

The research is quasi experiment that aim to know the influence of using Macromedia Flash on cooperatif learning model type NHT to achievment of students of class X SMA Negeri 12 Makassar. The independent variable are NHT type cooperatif learning model with Macromedia Flash and without Macromedia Flash based in cooperatif learning model, and dependent variable is students’ achievment in chemical bonding main subject of learning. The populasi is whole student of X Grade SMAN 12 Makassar which consists of 8 classes. The sample include two classes such as X2 as an experiment class with 36 students and X3 class as a control class with 36 students The sampling technique is random with assumption that the population is homogeny. Data collection technique is obtained from objective test which consists of 20 items of multiple choice. The data analysis technique used are descriptive statistical analysis and inferential statistical analysis. The hypothesis test using t test shows that tcalculate > ttable = 2,97 > 1,67 on α ═ 0,05. Conclude that using Macromedia Flash on Cooperatif Learning Model Type NHT gives effected positive to toward student’s achievement of class X SMAN 12 Makassar on Chemical Bonding subject matter.
