Abstract

This research aims to determine the relationship between self-efficacy and mathematical disposition with the mathematics learning outcomes of class X students in Mechanical Engineering at Vocational High School 7 Surabaya. This type of research is correlational research. This research was also an ex post facto study. The population in this study was the tenth grade students of Machining Technique at SMK Negeri 7 Surabaya, the sampling technique in this study was a saturated sample technique. The sample used in this study was 115 students. Data collection on self-efficacy and mathematical disposition was obtained by questionnaire method, while data on mathematics learning outcomes were obtained from mathematical tests. Thedata analysis technique used in this study is multiple correlation analysis with a significance level of 5%. The results in this study indicate that: (1) there is a positive and significant relationship between self-efficacy and mathematics learning outcomes. ; (2) there is a positive and significant relationship between mathematical dispositions and mathematics learning outcomes. ; (3) there is a positive and significant relationship between self-efficacy and mathematical disposition with students' mathematics learning outcomes. Based on the results of the partial correlation test, mathematical disposition variables have more influence on the students' mathematics learning outcomes variables.

Abstract

This study aims to produce a learning design to increase numeracy literacy and critical thinking character of elementary school students based on ethnomathematics using Polya's problem-solving steps. This type of research is library research. The results showed that Polya's problem-solving steps can be used to design learning syntax as follows. Polya's first step is to understand the problem of producing a learning design menu, let's get to know culture, learn to get flat, and learn numeracy through films or videos from the MK Modul NusantaraMBKM Dr Soetomo University. The second step is polya learning planning to produce a learning design menu for identifying flat shapes based on the questions in learning numeracy with number content, geometry & measurement, algebra, and data & uncertainty. The third step is to implement the lesson plan, produce a learning design menu, let's develop alternative answers. The fourth step is to reflect on learning to produce a learning design menu, let's reflect. Increasing numeracy literacy and critical thinking character can be built on the first, second, third and fourth steps of solving Polya's problems.

Abstract

This study entitled Effectiveness of Using Video Learning Media to Improve Mathematical Literacy in Bethel Christian Middle School Surabaya. This study aims to describe and analyze culture-based videos in improving mathematical literacy on square, triangleand quadrilateral material at Bhetel Christian Junior High School Surabaya in the 2021/2022 even semester. The method used is the research method used in this study is a Pre-Experimental Design using the One-group Pretest-Postet design form. In this design there is a pretest before being given treatment and a posttest after being given treatment. Data analysis itself uses normality test, paired sample t-test, Wilcoxon test, N-Gain test. From the results of the Wilcoxon test that has been carried out, it can be seen that the significance value is 0.001 so there is a difference in the average results of the pretest and posttest of the two samples of mathematical literacy and critical thinking of junior high school students. It can be concluded that the results of mathematical literacy and critical thinking of junior high school students towards culture-based videos can increase. From the results of the N-Gain test that has been carried out, which occupies a playing score of 0.4488, which means that culture-based videos are quite effective in improving mathematical literacy and critical thinking of junior high school students.
