This research including development research (Research and Development) aims to develop powerpoint-based learning media. The subjects in this study were students and fifth grade teachers of SD Negeri Gaddong I, Bontoala, Makassar. The development model used in this study is the Dick & Carey development model which consists of 5 stages: (1) the needs analysis phase, (2) the product development design stage, (3) the product development stage, (4) the product evaluation and revision stage , (5) Final product. This powerpoint-based learning media has carried out a trial process consisting of one-on-one trials of 11 people, small group trials of 21 people and class trials of 34 students. Powerpoint-based learning media that have been developed have been validated by experts and have been revised so that they can get results that are suitable for use in learning.Research data analyzed with descriptive method shows that powerpoint-based learning media developed are valid and effective. The trial was conducted in three stages, namely one-on-one trials, small group trials and class group trials to see the validity and effectiveness of the powerpoint-based learning media that had been developed. It is said to be effective because it meets the criteria with the results (1) the results of the validation of the media and the material are very good, (2) the teacher's response to the learning media is very good (3) the students' responses to the learning media are very good (4) the activities of students in the learning process are very active , ( 5) student learning outcomes improve. Thus, the results of this study can be used and developed in the learning process, especially in students of Gaddong I Elementary School, Bontoala District, Makassar City. As the implications obtained from this study, it is recommended that researchers interested in developing further research be expected to examine the limitations of this study.
This study is a research and development (R&D) which refers to 4-D development model. The objective of this study is to produce a valid, practical, and effective scientific approach-based learning module in Plantae concept. The study employed descriptive qualitative and descriptive quantitative approaches. The material experts validated the prototype 1. The prototype 11 was tested by using the experiment design of pretest and posttest only to examine the practicality level and effectiveness of Biology learning module developed at SMAN 2 Sengkang in class X MIA 1 of academic year 2015/2016. The result of the study revealed that the scientific approach based learning module was confirmed as valid. The practical level valued from the implementation of learning which used scientific approach-based learning module was in the high category. The effectiveness of module valued from the teacher's ability in managing the learning was in a proper category, the result of students' response was 94.61% which had the good response and students' learning result improved from 35.65 to 84.35 with completeness percentage by 94.11%. Thus, the conclusion of the study was the scientific approach-based learning module developed in Plantae concept was valid, practical, and effective to be used in Biology lesson.
THE EFFECT OF THE PROBLEM BASED LEARNING MODEL ON THE COGNITIVE ABILITIES AND CRITICAL THINKING SKILLS OF ELEMENTARY SCHOOL STUDENTSResearch has been done with the aim to knowing there is or not a significant positive effect of the problem based learning model on student’s cognitive abilities and critical thinking skills. To achieve the aim, this research was carried out using Pretest-Postest Control Group Design of research which belongs to the type of true experiment research. The results of the study showed the students' cognitive ability data included parametric data groups so tested with Independent Sample T-Test and critical thinking skills of students including nonparametric data groups so tested with Mann-Whitney obtained significance scores of 0.04 and 0.04 or less than 0.05, meaning the hypothesis was accepted. Wilcoxon's follow-up test as a pretest-posttest rank comparison test between the control class and the experiment showed that the experimental class's significance scores of both cognitive ability and critical thinking skills of students were 0.00 and 0.00 or less than 0.05, respectively, and included smaller than the significance of the control classes of 0.11 and 0.03 respectively which meant the hypothesis was accepted. Thus it can be concluded that there are a significant positive influence of the Problem Based Learning model on students' cognitive abilities and critical thinking skills.
