Abstract

The law of conservation of mass is a fundamental law and is related to other chemical materials such as chemical reaction equations so that student's learning obstacles of the law of conservation of mass must be overcome. One of the ways to overcome student's learning obstacles of the law of conservation of mass concept is the implementation of sharing and jumping task based lesson design, which is the aim of this research. The research method used is a qualitative descriptive research method. The research subjects were students of X.1 and X.2 SMA in Bandung and chemistry teacher who collaborate with researcher as team teaching. The data on the implementation of sharing and jumping task based lesson design of the law of conservation of mass was obtained from observations, tests, and interviews. Implementation of sharing and jumping task based lesson design of the law of conservation of mass concept was carried out twice. The result of the first implementation is that the previously identified learning obstacles still appear but in a smaller percentage. After the first implementation of the lesson design, it was revised and implemented in other class. The results of the second implementation can overcome student's learning obstacle who think that the mass of solids is heavier than the mass of liquids, but a small number of students still do not take into account the mass of gases in chemical reactions and do not fully understand the meaning of the law of conservation of mass.

Abstract

The material in chemistry subjects can be fully understood if the learning emphasizes the macroscopic, sub-microscopic and symbolic levels and links the three levels. The material for electrolyte and non-electrolyte solutions contains abstract concepts. Students only understand concepts that exist macroscopically and memorize concepts sub-microscopically or symbolically on the material, resulting in students having difficulty understanding the material. This study aims to describe the understanding of students' multi-representation of chemistry on the material of electrolyte and non-electrolyte solutions for class X MAN 2 Kota Padang. The research method used is descriptive quantitative. Samples were taken randomly, namely random sampling for class X IPA 6 as many as 34 samples. The instruments used are descriptive tests and interviews, the questions given include 3 levels of representation using Miles & Huberman data analysis techniques and data processing with Microsoft Excel. The results showed that 53% of students could connect the three levels of chemical representation of 6 questions, 44% of students could connect the three levels with 5 questions out of 6 questions and only 3% of students could connect the three levels with 3 questions out of 6 questions. The average understanding of the highest representation is on macroscopic representation because 98% of the number of students who have a very good understanding category, while at the sub-microscopic level only 9% of the number of students who have very good understanding category, and at the symbolic level 44% of the number of students who have very good understanding category.

Abstract

Practical activities during the covid pandemic are difficult to do because all learning has turned to online learning. So that students are required to carry out independent practicum at home, even though laboratory equipment and materials are quite expensive and difficult to obtain. A breakthrough is needed so that the practicum can still be carried out. One of them is independent practicum using simple equipment and materials. Independent practicum is implemented in basic chemistry courses during the odd semester. However, reflection on the practicum is needed to identify motivation and an opinion from student. The research design used was descriptive qualitative research. The research was conducted on students of the Chemical Education Study Program, University of Lampung. Data was collected by using a questionnaire through a Mentimeter. The results showed that (1) students were highly motivated to participate in independent practicum because it was interesting, (2) students' perception of independent practicum is very good, this is shown by the number of students who are helped in understanding the concept of chemistry after doing independent practicum, (3) the obstacle experienced by students during independent practicum is the difficulty of signaling in some areas which causes the upload of independent practicum videos to be often late. This research is relevant and can be a practical breakthrough for both lecturers and teachers who have limited laboratory equipment and materials by loosening the collecting of practicum videos.
