Abstract
The abundance of chemical concepts and general chemistry lessons that tend to be monotonous and have not yet considered the ability of mathematical thinking to cause problems in learning that resulted in low student learning outcomes. Even though the concept can be related to students' daily lives by applying effective learning models in accordance with teaching materials. The purpose of this study was to determine whether there were significant differences in learning outcomes between the classes taught with PBL models and the classes taught in the DI model in the General Chemistry course at the Chemistry Education department of FMIPA Unimed. The population consists of 2 classes, each of which consists of 26 students taught with different learning models. After the data is tested normal and homogeneous by using SPSS, the hypothesis is tested using t test. Based on the results of the hypothesis test, it is known that the value of Sig. 0.065 <0.10. So it was said that there were significant differences in learning outcomes of classes taught with PBL models with classes taught with the DI model in General Chemistry courses. This study concludes that for the General Chemistry subject learning, it is better to use the PBL model than the DI model. Keywords: DI model; general chemistry; project-based learning model; virtual lab
Highlights
Improving human resources in Indonesia, for instance by renewal in the field of education, namely by improving the quality of educators and education personnel by taking advanced study programs that are relevant in domestic and abroad, conducting training and upgrading, implementing Tri Dharma Perguruan Tinggi for lecturers, the existence of lecturer certification, Higher Education Accreditation and so on.In the conditions of cognitive conflict, students are faced with three choices, namely (1) retaining their original intuition; (2) revising some of their intuition through assimilation; and (3) changing their views and accommodating new knowledge (Rhedana, 2017).But the reality on the ground shows that educational achievement in Indonesia is still far below other Asian countries
Note : A1 = Group of student taught by Problem Based Learning (PBL) model A2 = Group of student taught by Direct Instructional (DI) model
There are various studies that link between the use of Virtual lab and Real labs such as research conducted by Tatli and Ayas (2013), which describes that “Virtual chemistry labs are slightly more effective than Real labs, both of which show the achievement and ability of students to recognize laboratory equipment”
Summary
Improving human resources in Indonesia, for instance by renewal in the field of education, namely by improving the quality of educators and education personnel by taking advanced study programs that are relevant in domestic and abroad, conducting training and upgrading, implementing Tri Dharma Perguruan Tinggi for lecturers, the existence of lecturer certification, Higher Education Accreditation and so on.In the conditions of cognitive conflict, students are faced with three choices, namely (1) retaining their original intuition (the ability to understand something without reasons, rationality, and intellect); (2) revising some of their intuition through assimilation; and (3) changing their views and accommodating new knowledge (Rhedana, 2017).But the reality on the ground shows that educational achievement in Indonesia is still far below other Asian countries. Improving human resources in Indonesia, for instance by renewal in the field of education, namely by improving the quality of educators and education personnel by taking advanced study programs that are relevant in domestic and abroad, conducting training and upgrading, implementing Tri Dharma Perguruan Tinggi for lecturers, the existence of lecturer certification, Higher Education Accreditation and so on. Based on the United Nations Development Program (UNDP) report, it was seen that the 2013 HDI (Human Development Index) was ranked 121 of 187 countries. Whereas in 2015, it is still around the order of 108 out of 187 countries (UNDP, 2015). Chemistry studies about the composition, structure, properties, changes in material, and changing energy changes. Chemistry subject can be packaged more than it is
