Abstract

This study aims to analyze the formative test items for the Mathematical Logic and Sets course in the Digital Innovation Program of the Mathematics Education Study Program, FKIP UAD in terms of classical test theory. This research is descriptive research. The analysis was carried out on 20 multiple choice test items which were tested on 51 students. The analysis was carried out on the difficulty and discrimination index and reliability with the help of the ITEMAN (Item and Test Analysis) package program. The results of the analysis of the difficulty index showed that of the 20 items, there were 6 items that were difficult and 14 items that were moderate. In terms of discrimination, 18 items had good discrimination index and only 2 items had poor discrimination index. One of the causes of low discrimination index is caused by items that are too difficult. From these results, further revisions were made to the items that did not meet the good criteria. Reliability estimation using the Cronbach Alpha formula shows that the measurement results obtained through this test are reliable.

Abstract

This research was motivated by students' low understanding of concepts. Based on the results of observations and interviews, it was found that there was a lack of variety in learning models and media as well as students' low comprehension and memory. This research aims to determine the influence of the Teams Games Tournament (TGT) model assisted by PUBBADAR media on the understanding of mathematical concepts of fifth grade students at SD 1 Getas Pejaten. The research population was all 38 class V students. This research is in the form of quantitative research using an experimental method, namely Pre-Experimental in the form of One Group Pretest Posttest Design. Data analysis took the form of a normality test and hypothesis test (Paired Sample T-Test) using the SPSS application. The normality test results produce a sig value. pretest reached 0.811 while the sig. posttest reached 0.349 which shows that the sig. pretest > 0.05 and sig value. posttest > 0.05. It can be said that the pretest posttest data is normally distributed. The results of the paired sample t-test show that there is a difference in the average pretest score, namely 57.92 and posttest 80.52. Meanwhile, the results of the paired sample t-test are 0.000 or 0.000 < 0.05. It can be said that Ho is rejected and Ha is accepted. It can be concluded that the application of the TGT model assisted by PUBBADAR media has an effect on the conceptual understanding of class V students at SD 1 Getas Pejaten.

Abstract

Cultural mathematics is an approach to designing mathematics that is relevant and closely related to cultural communities. Learning that focuses on cultural aspects becomes more interesting and enjoyable due to socio-cultural constructions, where mathematics has been integrated in human history and activities. This approach to learning that combines math and culture is known as ethnomathematics. One of the cultural and historical places is the Gedhe Kauman Mosque in Yogyakarta. This research aims to explore mathematical concepts based on the ornaments in the Kauman Gedhe Mosque and the value of character education for students. This research is qualitative research using ethnographic approach. Data were collected through interviews, field notes, observations, literature review, and documentation. Based on the results of the study, it was found that the concepts of mathematics in the Gedhe Kauman Mosque building in the form of flat geometry, geometric transformation, and character education values. This can be found in the ornaments of the gate, gate, front door of the mosque, side foundation of the foyer building, foundation of the main building, fort, main pillar of the foyer building, and the main door. Then character values include selflessness, hard work, responsibility, fortitude and wisdom, leader, and confidence.

Abstract

This research is motivated by the emergence of the transition to an increasingly massive distance learning process in Indonesia since the emergence of COVID-19 in Indonesia. The study aims to look at student perceptions of the distance learning process on student learning motivation. The design used in the research uses a type of quantitative research with a descriptive approach, the data collection process uses a questionnaire taken through Google Forms on active students of the ITBMP actuarial and digital business study program using descriptive data analysis. The data obtained is processed using the Likert method. The results of the study found from 11 statements that contained learning motivation indicators show that learning motivation is related to the process and methods in the learning process, the results of the questionnaire from six indicators obtained 16% got a positive response while 84% got a negative response. From the results of the research conducted by researchers, the results reveal that students have a low level of motivation towards distance learning.

Abstract

Reflective thinking ability is the ability to make connections between new information and previous information to solve problems by drawing conclusions.  Meanwhile, numerical ability is the ability to calculate. Both are very important for students in studying mathematics. Based on the results of pre-research test instruments conducted in class X SMA Negeri 1 Sukau West Lampung, data obtained that reflective thinking ability and numerical ability are still relatively low. This is due to the choice of learning strategies which are still monotonous. Therefore, researchers are interested in implementing the REACT (Relating, Experiencing, Applying, Cooperative, Transferring) Learning Strategy Assisted by E-Modules on Students' Reflective Thinking and Numerical Abilities. The population in this study were all class X students at SMA Negeri 1 Sukau, while the samples were students from classes X C, X D, and X F. Class X C is experimental class 1, class X D is experimental class 2, and class X F is the control class. This research uses a quantitative approach in this research using Quasi Experiment Design. The sampling technique is Cluster Random Sampling. In this research, the data collection techniques are observation, documentation and tests. The data analysis used was Multivariate Analysis of Variance (MANOVA) with a significance level of 5%. Based on the results of MANOVA research, it shows that the REACT (Relating, Experiencing, Applying, Cooperative, Transferring) learning strategy assisted by e-modules has an impact on students' reflective thinking abilities and numerical abilities.

Abstract

The experience of making and proving mathematical conjectures is valuable for students. The element of doubt in the conjecture gives students access to reasoning. All Calculus textbooks discuss limits, but most practice problems on the subject of limits are not specifically made as practice problems for making and proving conjectures. This study aims to describe problems on the subject of limits that can be used as practice questions to make and prove conjectures. The object of this research is the questions on the subject of limits related to geometry material in the book Calculus, 7th edition by James Stewart. This research method is a content analysis based on the praxeology model which consists of four elements of analysis, namely tasks, techniques, technology, and theory. The results show that the problems can be identified as exercises in making and proving conjectures, the steps in making and proving conjectures can be used to solve the problem, justification can be done to apply the steps in making and proving conjectures, and there is a theory used in justifying the steps in making and proving conjectures.
