Abstract

Mathematical thinking and self-confidence are indispensable aspects of learning mathematics and are influential in solving mathematical problems. In higher education mathematics learning, advanced mathematical thinking skills are required (Advance Mathematical Thinking. Advanced mathematical thinking processes include: 1) mathematical representation, 2) mathematical abstraction, 3) connecting mathematical representation and abstraction, 4) creative thinking, and 5) mathematical proof. Discrete mathematics is one of the courses in mathematics education FKIP UNS. The problems in Discrete Mathematics courses are usually presented in the form of contextual problems. Students often experience difficulties in making mathematical expressions and mathematical abstractions from these contextual problems. In addition, students also experience difficulties in bookkeeping. Most students often prove by using examples of some real problems. Even though proof in mathematics can be obtained by deductive thinking processes or inductive thinking processes, the truth is that mathematics cannot only come from the general assumption of inductive thinking. Based on this, a qualitative descriptive study was carried out which aims to determine the advanced mathematical thinking skills based on the level of student self-confidence. Research with the research subjects of FKIP UNS Mathematics Education Students in Discrete Mathematics learning for the 2019/2020 school year gave general results that the student's ability in advanced mathematical thinking was strongly influenced by the level of student confidence in learning. The higher the student's self-confidence level, the better the student's advanced mathematical thinking ability, so that high self-confidence has a great chance of being successful in solving math problems.

Abstract

In this study, we focused on the large inelastic behavior of a sandwich panel made of two solid plates as a stiffener and a honeycomb core shell subjected to blast load. The loading scheme was carried out using an explosive charge bullet mounted at a standoff distance of 100 mm with three mass variations of trinitrotoluene: 1, 2, and 3 kg TNT. The numerical simulations performed using ABAQUS/CAE were validated with the experimental results of a previous study. The geometrical effects of the sandwich panel on intact and damaged models were also numerically investigated. The panel was designed using a square and hexagonal honeycomb core. The effect of honeycomb core height was also observed by modeling the core using three height variations: 31, 51, and 71 mm. The results showed that the hexagonal core was more resistant to blast loads than the square design. The core height parameter determines the energy absorption based on these results. The structural strength is also affected by the damage. The findings of this study can be used to improve structural designs that utilize sandwich panels to withstand blast loads. Doi: 10.28991/CEJ-2022-08-05-014 Full Text: PDF

Abstract

One of the efforts to realize the vision and mission of the Government Islamic Junior High School 2 Surakarta (MTS N 2 Surakarta) to be one of the best schools at the national level is by participating in MYRES (Madrasah Young Researcher Super Camp), which conducted annually by the Indonesian Ministry of Religion. The school have participated in this event several times, but unfortunately, the result still needs improvement. After conducting a self-evaluation, there found some possible aspects that caused this situation. The lack of knowledge and experience in conducting research and writing academic articles of the teachers who became students’ supervisors indicated the main problem that caused this situation. Based on this situation, the Government Islamic Junior High School 2 Surakarta (MTS N 2 Surakarta), in collaboration with the Contemporary Mathematics Education Research Group of the Mathematics Education Department, Sebelas Maret University, has conducted intensive training for academic writing to be submitted to MYRES competition. This program was conducted for three months, from April to June 2022. This program comprised of some activities, a workshop on academic writing with a keynote from Yogyakarta State University, continued by intensive training conducted online and offline. Ten proposals resulted from this program, ten were submitted to MYRES, and two of the proposal finally can compete until the semifinal stage.

Abstract

A graph denoted by  is a pair of  where  is a non-empty set of vertices in G, and E is a set of edges in G. In graph theory, there are various types of graphs including star graphs, cycle graph, and wheel graph. Graph operations on two or more types of graphs can produce new graphs. Amalgamation is one of the operations on graphs. Suppose  and  are two connected graphs, amalgamating the vertices of graph 1 and graph 2 by joining vertices  and vertices   denoted by  is the graph obtained by joins vertex  of graph  and vertex  of graph  into one vertex , where  is the common vertex of the graph resulting from , while amalgamating the edges of graph  and graph  by joining edges  and edge , denoted by  are graphs obtained by combining edge of graph 1 and edge of graph 2 into one edge g, where g is common side of graph of (????1,????2;????,????). Vertex coloring is one of the fastest-growing topics in graphs. The coloring of the vertices, that is, assigning a color to each vertex of the graph so that each neighboring vertex has a different color. The minimum number of colors used to color the vertices of a graph is called the chromatic number. In this article, we discuss the chromatic number in the amalgamated graph of wheel graph and star graph and the chromatic number on the amalgamation of wheel graph and cycle graph. The results obtained are as follows: (1) the chromatic number of the amalgamated graph of the wheel graph () and the star graph () for n even is 3 and for n odd is 4, (2) the chromatic number of the graph resulting from the operation amalgamation of the wheel graph () and the cycle graph () for n even is 3 and for  odd is 4.

Abstract

This study aims to develop an educational game as a learning media for mathematics at the elementary school level, particularly fractions.  Named Fraction Bakery, this game was developed as a response to complaints of students' and teachers' difficulty in learning and teaching fractions. This difficulty, if poorly addressed, may serve as an iceberg-like issue for their understanding of more advanced mathematic concepts. Number recognition, including fractions, is fundamental to learning mathematics. As a teacher, it is necessary to evaluate such learning difficulties and seek alternative interactive learning media their students can enjoy. For the purpose of the study, the research and development model proposed by Thiagarajan, consisting of Define, Design, Development, and Disseminate stages, was applied. This game was still in the development process by evaluating the media value using trial responses involving undergraduate students of mathematics education at Sebelas Maret University. Regarding the product's interface, 71% of respondents gave a high score, 57% gave a very high score to the game animation, 75% stated that the game would likely motivate users to learn (affective impact), and 57% stated that the materials delivered in the game are highly relevant to the competency

Abstract

The purpose of this study was to develop an assessment system using Moodle e-learning to improve mathematics learning outcomes in terms of knowledge, skills and attitudes of students. The development design in this study is more on how to develop learning activities with authentic assessment that must be carried out by the teacher which of course will be very difficult if everything is paper-based. The implementation of a reliable assessment with easy administration by the teacher becomes the consideration of the researcher. And with regard to the pandemic conditions that are being experienced by the Indonesian nation, online learning is an option for students and teachers. Even in the assessment that must be carried out. For this reason, the Moodle application is an alternative that allows students to access teaching materials and practice problem solving easily. This is very interesting to do a development study in SMK, why? Because vocational students usually lack positive attitudes towards mathematics. The use of the Moodle application in learning mathematics in the classroom is certainly the teacher's job to limit the time to face students, and the lack of positive attitudes of these students into "energy" to optimize student abilities. This research was conducted at SMK Warga Surakarta, in class XII Machines, using the Thiagarajan RnD 4D steps, namely Define, Design, Develop and Disseminate. From this research, an authentic assessment instrument has been developed using the Moodle application on the Limit Function material. By reviewing the basic competencies in the Function Limit material, 20 questions were developed in the C2 (8 points), C3 (6 points) and C4 (6 points) categories and validated with a professional judgment on the test instrument. In the student attendance data, it appears that the desire of students to improve their understanding of the Limit Function material is quite high, more than 70% of students want to repeat the class independently. Also, the average student attendance was 13.4 out of 10 meetings planned in the teacher's lesson plan (1 meeting for the implementation of daily tests). From the average value of assignments, there was an increase in the grades in assignment 1 and assignment 2, but in assignment 3, the average score of student achievement decreased, this was possible because the material in assignment 3 was a continuation of the material for assignments 1 and 2, but if viewed from the frequency of doing assignments in each task session, there was a decrease in the number of frequencies. This can be seen in assignment 2, where the average student did the assignment 2.87 on task 1, and in task 2 the average student did 2.43 times with the results significantly increasing. Meanwhile, the average daily test for students in class XII M1 was 78.7, which means that the class average was above the school's KKM and 73.3% of students obtained learning outcomes above the KKM on the Function Limit material. It can be said that learning can improve student learning outcomes and motivate students, because from the response questionnaire, 86.7% of students said they were motivated to try the test to get good results.
