The Characteristics of Mathematical Literacy Based on Students’ Executive Function

<p style="text-align: justify;">Literacy ability is an individual's ability to reason, formulate, solve, and interpret mathematically to solve problems related to daily life. Executive function is a cognitive aspect that has a relation with mathematical literacy. One of some aspects that affects the low mathematical literacy ability is the aspect of executive function. This study aims to investigate the characteristics of mathematical literacy based on the executive function aspects of 15 years old students. A qualitative method with a descriptive approach is employed in this study. The present research applies interview guidelines, questionnaires, and students' mathematical literacy tests as the instruments. Research subjects are junior high school students in grade VIII from two different schools. The result shows that the students' executive function influences mathematical literacy ability. Students' mathematical literacy ability is not fully achieved by fulfilling all the indicators involved. Another aspect found in the research is the low critical thinking ability impacts the achievement of mathematical literacy ability indicators.</p>

Critical Thinking Ability and Performance in Argumentative Essays of the Education Major Students

The study was carried out to assess the relationship between students' critical thinking abilities and their success in writing an argumentative essay. The descriptive-correlation design was used in this research. The respondents in this survey were a total of 310 Education major students. This is 22.32 percent of the 1387 students enrolled in the Education program. The 50-item questionnaire was based on the Watson-Glaser Critical Thinking Appraisal from Pearson TalentLens to measure the student's study critical thinking abilities. The following conclusions were drawn: the students lack critical thinking ability; the students have difficulty in constructing argumentative essays; and the less critical the students are, the less performance they have in writing argumentative essays.

Pengaruh Model Penemuan Terbimbing Berbantuan WEB Terhadap Keterampilan Berpikir Kritis Matematis Siswa Kelas X

The background of this research is, there is no learning model that can optimally support critical thinking skills, so it takes an innovative learning model. In this case, the researchers used web helped to guide discovery learning model to improve the critical thinking skills of the student in class X SMAN 4 Praya in academic year 2019/2020. This study aimed to find an effect of web assisted guided discovery learning on trigonometry material to critical thinking ability of the student in class X SMAN 4 Praya in academic year 2019/2020. This study use a quantitative research approach to the type of experimental research. In this experiment the researchers used a quasi-experimental, and uses two classes as a research, the experimental class and control class. The population of this research is all the student in class X SMAN 4 Praya and and choose two class as a sample class that is X MIPA 5 as a experimental class and X MIPA 3 as control class. Student in experimental class used web assisted guided discovery learning model and in control class used guided discovery without web assisted. The result of the research showed that the average of critical thinking ability in the experimental class is better than control class which is in the experimental class is in the less effective category and control class in ineffective category.

TEXTBOOK AS A MEANS OF CREATIVITY DEVELOPMENT OF A STUDENT

The article provides a comparative analysis of primary school textbooks in Poland and Ukraine. Summarizing the results of the analysis of the approaches of different authors, the following functions of the school textbook are singled out: informational, managerial, developmental, communicative, educational, differentiation of learning, individualization of learning. It is established that in modern textbooks of New Ukrainian School (NUS) much attention is paid to: development of logical thinking; activity approach; work with information; development of students' critical thinking; ability to interact and communicate; creativity development. Tasks of a creative origin aimed at organizing the search activities of students and the development of creativity improve the developmental function of textbooks for primary school. One of the key trends is the use of “open” textbooks. It is noted that the “open” textbook promotes the creativity of teachers who become its contributors; in addition, the textbook is enriched with local realities. Key words: textbook, development of creativity, modern Polish primary school, creative potential, New Ukrainian School (NUS), reform.
