Abstract

The process of learning mathematics only focuses on understanding students but have not been able to develop their creative way of thinking. Students do not have the opportunity to explore answers or ways that are different from what the teacher teaches, so students cannot be creative in finding answers. The application of the creative problem solving learning model and concrete media in the form of nets of cubes and blocks is one solution to this problem. The purpose of this research is to find out: the difference in the average value of creative thinking skills after using the creative problem solving model and concrete media for fourth-grade students at SDN 1 Kaliombo. The experimental approach used in this research is the Pre-Experimental Design model in the form of a Pretest-Posttest Group Design. This study used fourth-grade students at SDN 1 Kaliombo as subjects, taking samples using total sampling or census. The research data was obtained from a statistical analysis of the t-test in the form of a Paired Sample t-Test. This study shows that: there is a difference in the average value before and after using the creative problem solving model and concrete media with a significance of 0.000 <0.025. Therefore, the CPS model assisted by concrete media can be said to have an effect on students' creative thinking abilities.

Abstract

Junior high school of mathematics Olympiad is one of the routine activities every year in Indonesia. Analysis of the items on the Mathematical Olympiad test instrument has been carried out by several researchers using the concept of classical test theory. The theory has many weaknesses when compared to the concept Item Response theory (IRT). The purpose of this article is to describe the analysis of pre-Olympiad mathematics test instrument for junior high school students in Pacitan East Java based on the IRT. This analysis was carried out using a quantitative descriptive method. IRT-based item analysis was performed using R software with the package irtawsi. The results of the analysis with the package show that the instruments used fit to 2PL model. From the 15 items used, there were two items that did not fit, namely items 4 and 9. Furthermore, from the 13 test items that were fit, there were 3 items that did not meet the quality of the discriminant parameter used. These three items are 1, 6 and 13 items, these three items must be dropped because they can provide biased information when used to estimate students' math olympiad abilities. Based on this information it can be concluded that there are 10 test items that have quality that meets the qualification parameters of difficulty and discriminant with a standard error of 0.25.

Abstract

Concepts in mathematics include abstract concepts, especially for elementary students. So that teachers are required to always innovate in learning so that learning is effective, not boring and students more easily understand concepts correctly. This learning requires media that is appropriate to the material and cognitive development of students. The media used in this research is result determining lamp to determine the least common multiple (LCM) and the greatest common divisor (GCF) of a number. This study aims to discuss the effectiveness of result determining-lamp media to determine the results of  LCM and GCF in grade IV students at SDN Peterongan Jombang. Effectiveness in research is seen from how the average learning outcomes and whether there are significant differences in student learning outcomes with and without the result determining-lamp media. Sampling uses a saturated sample, so that all class IV is used as a sample. Based on the results of the study, it was concluded that the use of result determining-lamp media is an effective determinant of learning outcomes because the average learning outcomes of the experimental class are higher than those of the control class and through the t-test there are differences in the learning outcomes of class IV students with and without the result determining-lamp media.

Abstract

This study aims to describe the mathematical literacy of grade XI students of SMA Negeri 2 Karanganyar in solving the PISA problem model in terms of the Adversity Quotient. For some students, mathematical concepts can be difficult to grasp, causing frustration and disinterest with the subject. For others, external factors such as lack of resources, inadequate teaching methods, and inadequate support can contribute to poor math performance. This research is included in qualitative research. The data used were obtained from test results and interviews. The subjects of the study were carried out by grade XI students of SMA Negeri 2 Karanganyar. Data analysis procedures in this study are data collection, power reduction, data presentation, and conclusion pulling. Checking the validity of power in this study using triangulation techniques/methods. The results showed that (1) Students with climber type AQ were able to explain answers fluently and clearly, able to mention after facts, solve problems with simple strategies in solving problems. (2) Students with campers-type AQ are capable and some are unable to explain answers fluently and clearly, solving problems with simple strategies in solving problems. The types "climber" and "camper" are often used to describe patterns of behavior that can be observed in the context of AQ, there may not be a "quitter" type listed because the main focus of AQ is on the positive and adaptive aspects of facing challenges and difficulties.

Abstract

The Covid-19 pandemic has caused the learning process to be hampered and cannot be carried out face-to-face. Therefore, a solution is needed for this problem. One alternative to overcome this problem is online learning. This study aims to describe the effectiveness of online learning using online media during the Covid-19 pandemic in Mathematics courses. The subjects of this study were 51 students in the Faculty of Science and Technology, Nahdlatul Ulama University, Purwokerto. They were from five different study programs, namely Agrotechnology, Mathematics, Biology, Fisheries Science, and Agricultural Biosystems Engineering, who had taken mathematics courses. This study was carried out in June – August 2021. This study used closed, semi-closed, and open-ended questionnaires as research instruments. Then, the data collection procedure was done through Google Forms. The data obtained were then selected using purposive sampling. To get valid and reliable data, triangulation was applied in this study. Triangulation was carried out through interviews with five students whose data were selected randomly. The researchers used descriptive statistics as the data analysis. The study found that the activities most often carried out by students during Study From Home (SFH) are playing on cellphones or laptops, doing assignments, working, and sleeping. Then, related to online learning, students prefer to use WhatsApp Group media and lectures. The preferred assignments or assessments are individual assignments and quizzes. Furthermore, the learning model most favored by students is the face-to-face learning model because students consider online learning ineffective. The results of this study can be used as a reference in choosing the suitable model, method, and learning media. Therefore, online learning can be held effectively and easily accepted by students during the Covid-19 pandemic.
