Abstract

Covid-19 menyebar secara global memicu pemerintah mengambil kebijakan-kebijakan untuk menanggulangi penyebarannya. Kebijakan tersebut ditindak lanjuti sekolah maupun perguran tinggi dengan menonaktifkan kegiatan perkuliahan secara fisik di lingkungan kampus dan memanfaatkan teknologi virtual dan digital. Penelitian ini merupakan studi kasus menggunakan pendekatan kuantitatif untuk mendeskripsikan penggunaan Spada selama masa Covid-19 di Universitas PGRI Adi Buana Surabaya. Data dikumpulkan melalui metode angket, dokumentasi, dan wawancara. Berdasarkan data yang sudah disebar memalui google form diperoleh hasil bahwa mayoritas dosen di Universitas PGRI Adi buana Surabaya menerapkan Spada selama masa pandemi Covid-19. Sistem pembelajaran daring yang digunakan mayoritas dosen bukanlah virlenda tetapi lebih menggunakan aplikasi zoom meeting. Hal ini diperkuat dari hasil respon angket yang disebar kepada mahasiswa melalui google form diperoleh informasi bahwa aplikasi yang sering digunakan dalam proses pembelajaran adalah zoom meeting. Berdasarkan hasil perhitungan menunjukkan bahwa sig < 0.05 artinya tidak ada pengaruh penggunaan Spada selama masa Covid-19 di lingkungan Universitas PGRI Adi Buana Surabaya. Sehingga tidak ada pengaruh antara prestasi belajar mahasiswa sebelum penerapan Spada dengan setelah penerapan Spada di lingkungan Universitas PGRI Adi Buana Surabaya.

Abstract

This study aimed to describe students' learning trajectory to solving math problems based on student’s ability. The subject is 4th-gradestudents of Madrasah Ibtidaiyah (MI) K.H. Mas Mansyur Surabaya. The results obtained by learning trajectory are (1) high ability students, expressing the understanding of the problem orally and writing, plan two solutions process, choose to use multiples and sum between departure time and travel time, the subject re-examine every step in solving the problem. (2) medium ability students, expressing an understanding of the problem orally, planning a solution and implementing it until finding a solution, in re-examining the subject using factoring; and (3) low-ability students, expressing an understanding of the problem orally, planning a solution to finding a solution, then simply re-examining the steps taken in solving the problem.

Abstract

This study aims to describe students’ thinking process in solving the problems of generating function. This is a case study that classifies students into three categories: high, medium, and low. Subjects were asked to solve the problems then use think aloud to reveal their thinking process. The results show that in understanding the problem, using conceptual and procedural knowledge related to the problems, strategies, and experiences they have in solving similar problems between the three subjects is different. Subjects with high and medium capability are able to reveal the problem-solving component of Polya in detail, whereas low-ability subjects use only some of the problem-solving components of Polya.

Abstract

Semantic is associated with the relationship between symbol, reference, and the problem’s context involved in the problem-solving process which also involves reasoning and decision-making. Hence, this study describes the characteristics of students’ semantic reasoning to solve the double discounts problem. 51 high school students in Sidoarjo participated in this qualitative study. The data were collected through 15-20 minutes problem-solving tests. The students' answers were grouped into correct and wrong answers. The correct answers were then regrouped once more based on the strategies used by the students to answer the test and to identify their semantic reasoning characteristics. The data were analyzed by reducing, classifying the think-aloud and observing. Then the similarity of characteristics of students' semantic reasoning when solving the double discount problem was identified. To test the accuracy of the data, triangulation method was used. This semantic reasoning was identified by  (1) giving the problem situation, (2) stating the keywords and their meaning, (3) stating the relationship, (4) transforming it into a mathematics statement, (5) calculating based on their strategies, (6) decision making, and (7) completing the answer interpretation. This study contributes to developing basic knowledge in interpreting each process of solving ill-structured problems until finding a solution.

Abstract

Problem posing is a learning approach that trains students to be able to process and communicate mathematical problems based on information obtained. This study aims to describe the ability of high school students to pose problems on the topic of system of linear equations in two variables (SLETV). This study used a quantitative descriptive study involving 60 high school students in the East Surabaya area. The results showed that students were able to submit 60 problems, consisting of 54 problems can be categorized and 6 problems could not be categorized. Based on the semantic structure of mathematics, 17 students (31.48%) were able to pose problems using 1-relationship, 13 students (24.07%) were able to pose problems using 2-relationships, 13 students (24.07%) were able to raise problems using 3-relationships, and 11 students (20.37%) were able to pose problems using 4-relationships. Based on language structure (syntax), 13 students (24.07%) were able to pose problems using assignment propositions, as many as 17 students (31.48%) were able to pose problems using relationship propositions, and 14 students (25.93%) were able pose a problem using a presupposition proposition.

Abstract

63 students were involved in the study and elected Rizka as the subject of research. This is a case study aimed at describing the cause of Rizka's failure in solving ill-structured problems about the rectangle. The results showed that the subject was able to represent the problem with own language. Rizka failed to build a solution that corresponds to the problem due to partial mastery of the rectangular concept. Rizka uses trial and error because it fails to associate a problem with a square concept that is the key to problem-solving success. Rizka success in the justification process because the process is counting without giving meaning. Meanwhile, the monitoring and evaluation process carried out by Rizka has failed. Rizka confusion determines the final solution because the solution is built does not qualify the problem solution. This is where the Rizka fails to provide the final solution. In this case, teachers have a role to teach their students to build relationships between concepts that can be utilized in problem-solving.

Abstract

This study was motivated by the difficulties of students transforming the data into frequency tables and graphs and appreciate a group of data. This is envolve in low student understanding. Encounter this situation, researchers felt the need to carry out CAR to rise these problems through PjBL supported by Virlenda and Whatsapp due to the pandemic situation that did not allow offline learning. So, the purpose of this study is to enhance students' statistical understanding through PjBL supported by Virlenda and Whatsapp. The subject 10 students from the 2019-C class of mathematics education program, Universitas PGRI Adi Buana Surabaya. Data were collected through observation, documentation, and tests. The data were analyzed quantitatively and qualitatively. The indicators of this study are there is no statistical understanding of students in the category less than "Good Enough" and observation components such as the focus of attention, activity, interest in learning, and seriousness of at least 70% of students. The results of this study, (1) the statistical understanding of all students in the minimum category of "Good" in the second cycle; (2) The observation component to the focus attention, activity, interest, and seriousness in learning satisfy criteria. This shows that the practice of PjBL supported by Virlenda and Whatsapp can improve the statistical understanding of students of mathematics education class 2019-C.

Abstract

Performance assessment is one alternative assessment can be done by teachers during the learning process. In this research, performance assessment carried out to discover the properties of a square by using learning media. Media that used in this research are square from asturo’s paper. Task students in groups to identify the properties of the square. Instrument that used in this research is the observation student’s performance. Data were analyzed by summing the scores given by observers. The result is the performance of students in discovering the properties of a square is in “good” category. This means that students work on tasks assigned to the worksheet that given by teacher and accordance with the instructions given on the worksheets.
