Penelitian ini bertujuan untuk menganalisis sekaligus mendeskripsikan kemampuan berpikir aljabar siswa berdasarkan tingkat efikasi diri mereka dalam pembelajaran matematika. Metode yang digunakan adalah kualitatif dengan pendekatan deskriptif. Subjek penelitian adalah siswa kelas VIII C SMP Muhammadiyah 9 Surabaya. Hasil penelitian menunjukkan bahwa tingkat efikasi diri berpengaruh nyata terhadap kemampuan penyelesaian masalah matematika siswa. Siswa dengan efikasi diri tinggi mampu memahami permasalahan dengan baik, memodelkan ke dalam persamaan matematika, serta menyelesaikan masalah dengan langkah-langkah penyelesaian yang benar sehingga memperoleh jawaban yang tepat. Sementara itu, siswa dengan efikasi diri sedang relatif sudah mampu membuat pemodelan persamaan dan mengikuti prosedur penyelesaian, namun masih sering melakukan kesalahan pada operasi perhitungan maupun penulisan jawaban akibat kurang teliti dan kurang fokus. Adapun siswa dengan efikasi diri rendah menunjukkan kesulitan dalam memahami soal, kurang mampu menuliskan langkah penyelesaian dengan runtut, serta sering melakukan kesalahan dalam pemodelan maupun perhitungan sehingga tidak dapat menarik kesimpulan secara tepat. Dengan demikian, dapat disimpulkan bahwa semakin tinggi efikasi diri siswa, semakin baik pula kemampuan mereka dalam menyelesaikan masalah matematika, sedangkan efikasi diri rendah cenderung berdampak pada lemahnya pemahaman dan hasil penyelesaian soal.

Challenges in the 21st century are increasingly complex, technology is developing rapidly and competition is getting tougher. Therefore we need quality human resources that can keep up with and anticipate the times. The use of technology involves computational thinking (CT) skills which are closely related to the problem-solving process. The stages in computational thinking are part of mathematical thinking, meaning that learning mathematics can support students' CT skills. Through the development of digital pedagogical models in CT integrated mathematics learning, it can improve problem-solving skills. This research uses design based implementation research with 4 phases including; preliminary research, prototyping, results, and design principle. The participants were 28 grade 8 junior high school students who took part in two rounds of experiment in direct CT activities and digital CT activities. In this paper, we present an iterative mathematical problem-solving process in the digital pedagogy model. The computational task, environment, tool and practices were iteratively improved over two rounds to incorporate CT effectively in mathematics. The results from CT environment demonstrated that direct CT activities are more effective than digital CT activities in mathematical problem-solving. Based on empirical research, we summarize the characteristic of the digital pedagogy model from computational tasks, computational environment and tools, and computational practices in mathematical problem solving.

Abstract: How is the Process of Mathematical Literacy When Viewd From the Initial Mathematical Performance? The role of mathematics functionally in the context of everyday life which refers to the ability of individuals to respond to needs and obstacles in society is known as the conception of mathematical literacy. Mathematical literacy is an important aspect that every individual has to face the 21st century, there are 3 important processes in mathematical literacy, namely formulating, employ and interpreting mathematical results into everyday problems, besides that students' initial mathematical abilities are important and related to mathematical literacy. Therefore the aim of this research is to analyze the process of mathematical literacy in terms of initial mathematical abilities. This research is a qualitative descriptive study with a subject of 3 students consisting of 1 student each with high, medium and low initial math skills in junior high school students in Cimahi. The instruments used in this study were a Mathematical Literacy test instrument consisting of 3 questions, an initial mathematical performancetest and an interview guide. The results of this study indicate that students with low performance cannot carry out the 3 processes of mathematical literacy (Formulation, employ and interpreting), students with moderate abilities can formulate problems in mathematical form and use mathematical concepts for problem solving but are still wrong in doing calculations and unable to interpret the information contained in the table/diagram. Whereas for students with high initial mathematical performance, they can formulate everyday problems in mathematical representations, they can also use concepts, facts and procedures for problem solving but are not yet precise at the stage of interpreting and communicating in writing Keywords: mathematical literacy, initial mathematical performance.DOI: http://dx.doi.org/10.23960/jpp.v14.i1.202446
