Abstract

This study aims to examine the mathematical communication skills of students whose learning using Problem Based Learning approach GeoGebra assisted compared with using ordinary learning. This research is using the experimental method. Population in this research is a student of class X SMAN 1 Parongpong West Bandung academic year 2017/2018 with a sample of research is a student of class X SMAN 1 Parongpong consisting of class X Mia 1 as control class and X Mia 4 as experiment class is taken at random. The instrument used in this research is a test of mathematical communication ability in the form of problem description as much as 8 questions, as well as Self Confidence scale. Data were analyzed using IBM SPSS Statistic 1.7 for windows program. From this research, the following results are obtained: (1) Improvement of mathematical communication ability of students whose mathematical learning using geographic assisted PBL approach is better than using ordinary learning. (2) Increased self-confidence of students using geographic-assisted PBL approach is better than students using conventional learning Keywords:       Communication Ability, Self Confidence, Problem Based Learning, Geogebra

Abstract

This research is motivated by the low ability to understand mathematical concepts possessed by prospective elementary school teacher students. This study aims to see the achievement and improvement of students' mathematical understanding abilities that use Microsoft Excel-based VBA teaching materials with those using conventional learning. This study uses a quasi-experimental method with a non-equivalent pre-test and post-test control group design. This study's population were all second-semester elementary school teacher candidates in one private university in West Java, Indonesia. The sample in this study was 70 prospective 2nd-grade elementary school teacher candidates. The instrument used in this study was a test of understanding mathematical concepts. The results showed: 1) learning using VBA Microsoft Excel as a teaching material was able to improve students' ability to understand mathematical concepts; 2) learning using Microsoft Excel VBA as teaching material is better than conventional learning; and 3) students can be enthusiastic, active and motivated in learning mathematics with VBA Microsoft Excel.

Abstract

Now, the whole world is facing the coronavirus pandemic. In the meantime, students in China are required to do social distancing and not go to school. This coronavirus pandemic resulted in the use of online learning to teach students. In this research, we will get to know the students’ learning attitude towards online learning during the coronavirus pandemic. The sample population for this research are students in West Java, Indonesia. The data will be collected by using questionnaires and there was a total of 16 questionnaires that is collected for this research. The result of this research shows that online learning during this coronavirus pandemic is not very effective. Also, the students’ learning interest towards online learning is also very low. Based on the interview done on students and teachers, most of them stated that there are various factors that can affect online learning in China such as learning environment, internet and etc. The suggestion that is given in this research is that aside from online classes, teachers can also use video learning media that are used by developed countries so that it can solve the bad internet problem. The result of this research hopefully, can become a reference to improving a more effective learning media that can be used during the coronavirus pandemic in Indonesia.

Abstract

The Covid-19 outbreak has an impact on the provision of education. One of them is the process of online assessment or examination. Difficulties occur during online exams; weak supervision can increase cheating behavior among students. Generally, teachers or lecturers think about how to prevent this behavior. However, what if they are allowed to "cheat" on the exam? What do they think? This paper discusses students' perceptions when they were allowed to access various sources during online math exams. What benefits do they get?. The survey was conducted on 78 students of the Mathematics Education Study Program of UIN Sultan Syarif Kasim Riau. The data obtained through a questionnaire were analyzed descriptively. The results of the descriptive analysis showed that the students gave a positive response. The results of this study are expected to be a positive view of the weakness of supervision during online math exams, an idea/way to prevent cheating. In its application, both online learning and assessment, it is necessary to strengthen the character and self-concept of students.
