Abstract

Mathematical literacy requires individuals to solve a problem and also apply mathematics in everyday problems, which results in the ability to interpret solutions to those problems. In PISA it is known that Indonesia's mathematics literacy score is among the lowest, as well as in Guguk District Lima Puluh Kota Regency. One way to overcome this is to start introducing literacy to students early on. The introduction of literacy must be instilled in students since they are still in elementary school. Based on this, a training program and workshop was held regarding the application of mathematical literacy in mathematics learning in elementary schools in Guguak District with elementary school mathematics teacher partners who are members of the KKG SD Gugus III Kecamatan Guguak Kabupaten Lima Puluh Kota.

Abstract

The 2015 PISA (Program for international students assessment) results put Indonesia in 65th position out of 72 countries. The results show that the mathematical abilities of Indonesian students are still very low. These low abilities include. : (1) understanding complex information; (2) theory, analysis and problem solving; (3) use of tools, procedures and problem solving; and (4) conducting an investigation. These four abilities are known as high-order thinking skills (HOTS). Similar conditions are also found in the city of Payakumbuh. Based on interviews with several elementary school teachers from Payakumbuh it was revealed that students were not used to solving problems that demanded HOTS because in general teachers are also not trained to design mathematical problems with high cognitive levels. They tend to give questions at low level. As a result, this is not developing students' mathematical abilities. Based on this, a community partnership program was implemented with the aim of increasing the ability of elementary school teachers to design questions to assess HOTS. The activity partners were high school elementary school teachers in Groups 1 and 3 of Payakumbuh, which numbered 55 people. Activities are packaged in the form of a combination of workshops and implementation in schools. In the workshop, the teachers were given knowledge and skills in designing HOTS questions by the resource person. Next, the teachers in groups designed HOTS questions. The questions that have been designed by the teacher are validated together, then tested to students in grades IV, V, and VI. Based on the collected data, it is known that there was an increase in the ability of high-class teachers in Elementary Groups 1 and 3 of Payakumbuh in solving HOTS questions. The ability of the teachers to design HOTS questions also increased, although some of the questions that were designed were still slightly above the application (few still want high analysis, evaluating, or creating).

Abstract

The ability to think critically and the ability to think creatively are two important things in mathematics. These two skills are the focus of learning in the 21st century to prepare students for the challenges of the future. For this reason, it is necessary to provide training for teachers so that they can prepare their students to have these two abilities. For this reason, the team through the community partnership program (PKM) carries out activities to train teachers to be able to design lessons that can improve students' critical and creative thinking skills. The mechanism for implementing PKM activities is carried out using action research steps. In the action phase for the first activity, the teachers will be introduced to critical and creative thinking skills. They are also given examples of learning activities that can improve critical and creative thinking skills by integrating the use of technology such as geogebra software in learning and implementing learning activities into geogebra classrooms. The designed activity will be implemented in schools with the guidance of the PKM team and jointly evaluated in a focus group discussion (FGD) with mathematics MGMP teachers in West Sumatra. The teachers felt an increase in their ability to design lessons, especially by using the geogebra application and being able to implement it into a geogebra classroom.

Abstract

The result of 2015 PISA (Program for International Students Assessment) test which placed Indonesia in the 65th position of 72 countries showed the importance to improve the level of students thinking ability. There are many ways to improve the students’ thinking. One way to do that is by giving the students drill to solve higher order thinking problems. However, this solution is difficult to implement because designing HOTS (Higher Order Thinking Skills) problem is difficult for the teachers. Therefore, 20 junior high school mathematics teaches ware selected in order to give them training and workshop to improve their ability to design higher order thinking skills using action research methods. Three stages ware implemented in this training and workshop. First, introduction to HOTS, Second, designing HOTS Problems, and third, trying out and evaluating the test result. Product of the workshop are 30 mathematical problems in certain topic in which 15 of them are HOTS problems. To measure the effectiveness of the training and workshop, the result of pre-test and posttest were compared. Based on the data analysis, there was an increase of the ability of mathematics junior high school teachers to design problems to assess the higher order thinking skills.

Abstract

Integral is one of major topics in Calculus course. Many university students fail in calculus course because their understanding on the concept of Integral especially in understanding definition of integral is low. This situation encourages us to design a calculus lesson to build students understanding on Integral especially integral definition by using Realistic Mathematics Education as an approach. For that, we try to design a series of instructional activities starting from introducing sigma to definition of Integral in order to know students difficulties in understanding this topic. Some first-year university students in Universitas Negeri Padang are chosen to test our Hypothetical Learning Trajectory (HLT) in our preliminary research. The result is students had difficulties in connecting the sigma, area and definition of integral. This happens because the students did not see that the activities that have been designed as a whole that cannot be separated. Therefore, it is recommended to design a series of instructional activities which is focus on connecting sigma, area and definition of integral.

Abstract

This study aims to analyze the mathematical reasoning abilities of students in the mathematics education study program in the secondary school mathematics curriculum review course. This research was conducted by giving quiz questions in the form of descriptions to a class of students who were then analyzed the answers. The results of the student's answer analysis show that the students' mathematical reasoning ability is still low. The low level of students' mathematical reasoning skills in general lies in the ability of students to analyze problems, make conjectures, determine relationships between variables, and identify links between processes or concepts in a given case. So that many answers from students are not logical and wrong in concluding.

Abstract

The most essential thing in mathematics is proof, it makes mathematics being different with other subjects. One of subject in mathematics that always need prove to understand the concept is abstract algebra. In studying abstract algebra, student need various abstract concepts to include in its concepts. It is hard for student to understand the structures in abstract algebra and prove some of mathematical object that satisfy the structures. Group and its properties is the first structure in abstract algebra that has an abstract concept. It is hard for student to understand some objects, that is proven satisfy a structure and why the proof steps just flow. By giving explanation and reason in every proofing step, we try to increase student proving level and reduce the abstraction level of the concepts. To see how this module reduces the abstraction level in teaching group, this module is applied to university students and evaluated by interviewing and questionnaires to the students. Base on student response and by some perspectives, student proving ability increase and the abstraction level of the concept is diminished in some aspects.
