Abstract

This research aimed to determine differences in critical thinking ability and conceptual understanding between students taught with guided inquiry learning combined with metacognition training and students taught with guided inquiry learning without metacognition training. This study used quasi-experimental with pretest-posttest nonequivalent control group design. This study used a purposive sampling which produced two classes, namely class XI MIA 3 as the experimental class and XI MIA 4 as the control class. The students in the experiment class were taught with guided inquiry learning combined with metacognition training, while the students in the control class were taught with guided inquiry learning without metacognition training. The instrument used to measure the success of this research was multiple choice questions with written explanation. Multiple choice questions were used to measure conceptual understanding while essay questions were used to measure critical thinking ability. The results showed that: (1) The improved critical thinking ability could be seen from the mean of N-Gain of the experimental class 0,76, higher than the control class 0,55; (2) The improved conceptual understanding could be seen from the mean of N-Gain of the experimental class 0,66, higher than the control class 0,54. So we can conclude that the guided inquiry learning combined with metacognition training has enhanced students' critical thinking ability and conceptual understanding.

Abstract

The research was aimed to know the difference of conceptual understanding between two groups who was learned by guided inquiry with static visualization (IT-vis) and guided inquiry with analogy (IT-log) on galvanic cell Quasy experiment which nonequivalent posttet only control group design was used n this research. Learning chemistry must be explicitly to give submicroscopic aspects such as flow of electron and migration of ions. Static visualization visualises directly submicroscopic aspect by giving particulate image, but analogy visualises undirectly submicroscopic aspect by giving verbal information (analog concept). The result of mann whitney u test showed that conceptual understanding between two groups is significantly difference. Mean rank of IT-vis 32,88 is higher than IT-log 28,12. Studets’ conceptual understanding of IT-vis is higher than IT-log on galvanic cell. The difference characteristic of static visualization and analogy can influence students’ conceptual understanding.

Abstract

This study aimed to look at the effectiveness of the PBL-MR learning model to improved problem solving skills of students with different levels of self-efficacy. The effectiveness was seen from the difference in the level of problem solving of students in the topic of reaction rate PBL-MR and PBL learning models. The difference in the level of self-efficacy was seen from the differences of self-efficacy of students in one class where the students had been grouped into high and low levels of self-efficacy based on the questionnaire. This study used an essay test instrument that had a content validity of 94% with a very good category and a reliability coefficient of 0.842 with very high reliability criteria. The research sample was taken from two 11th year classes of SMAN 2 Malang. The results showed that there were statistically significant differences in problem solving abilities of students in both research classes (sig. 0.000) and there were also differences in problem solving skills between students with high and low levels of self-efficacy (sig. 0.028). The interaction of the model and self efficacy also produce significant impacts on problem solving ability (sig. 0,042).
