Axiomatic Systems

The teaching of geometry in the elementary school can be an exciting experience; children are receptive to experimentation, and many activities can be devised to facilitate learning. Generally, however, the use of exploration in geometry decreases as students progress through school and as they begin the study of formal axiomatic systems. In the higher grades we need to present interesting uses of geometry that will allow students to develop their powers of exploration and problem solving. The purpose of this article is to outline an example of how geometry serves as a model in the real world and to suggest how it might be used at the high school level.

<p>This study explored the relationship between school level and the psychosocial construct of a growth mindset school culture. Data was collected on the What’s My School Mindset (WMSM) Survey from a stratified random sample of PK-12 faculty and administrators (n = 347) in 30 schools across a large northwestern state. The overarching research question was, “Is there a relationship between school level and a school’s growth mindset?” Results revealed a significant decrease in the WMSM mean between elementary school level and high school level participant self-reports. Therefore, the results of this study could be used to create opportunities for faculty dialogue and reflection to changes perspectives, inform future practice, provide realistic ways to implement change by using research-based evidence to challenge assumptions; and give sound reasons for new practices.</p>

Math Problems

Learning mathematics is a crucial part of education. Mathematics is one of the subjects feared by students. One of the problems in the object of mathematics study is the material for X class of Senior High School. Students of grade X are undergoing adaptation from the junior high school level to the high school level so that the findings of conceptual errors, calculations, and thinking patterns in problem-solving algorithms are often found. This also happened to the students of the Muhammadiyah Senior High School Special Program of Kottabarat Surakarta. In connection with the above problems, the author analyzes student errors in solving math problems at the Muhammadiyah senior high school special program of Kottabarat Surakarta.This study aims to find out errors, causes of error, and alternative problem solving related to students' errors in solving math problems. This research is qualitative descriptive research. The research subjects were taken by sampling purposes.  they are three students of class X. The research method used is qualitative research methods, data collection techniques used in this study are test methods, interview methods, and documentation methods. The research instrument is the main instrument, namely the researcher himself and the auxiliary instruments in the form of test sheets, interview guidelines, and field notes. The data analysis technique uses data reduction, data presentation, and data verification, and triangulation techniques. The results of this study indicate that the types of errors that did most often made are errors in understanding questions that were 9 times, process skills errors and coding errors were 6 times, and reading errors were never made by research subjects.

Aim. In Italy, a handbook has been developed based on the principles of cooperative learning, life skills, self-effectiveness, and problem-solving at high school level. Early studies have shown the handbook’s effectiveness. It has been hypothesized that the revised handbook could be more effective in middle schools. Method. The study design is a “pre- and posttest” that compares the results obtained from 91 students of the high schools with those of the 38 students from middle schools. The assessment was made through “self-reporting” questionnaires of (a) learning skills including problem-solving and (b) perceived self-efficacy in managing emotions, dysfunctional beliefs, and unhealthy behaviours (i.e., drinking/smoking). Results. Significant improvements were observed in both groups with the exceptions of perceived self-efficacy in managing emotions. The improvement of dysfunctional beliefs and the learning of problem-solving skills were better in middle schools. Conclusion. The results confirm the authors’ hypothesis that the use of this approach is much more promising in middle school.

The purpose of this study was to explore the students’ problem solving skill to solve problem in Archimedes principle on the senior high school level. The method of this study was mixed method with explanatory follow up explanation design. The subject of this study was 30 students of k-11 in SMAN 9 Malang. The kuantitative data was collected through survey by 2 essay questions with reliability cronbah alpha 0,70. The qualitative data was collected through interview after analyze student answare. The aim of this interview was to follow up the pattern of student answare. The result of this study shown that students’ expert attitude began solve problem through definite problem qualitatively. In addition, the students’ novice attitude refer to not describe a problem qualitatively.

In teaching statistics at the high school level, we attempt to give students an appreciation of the usefulness of statistical measures and techniques. But too frequently we create a group of number-crunching robots who grind through formulas and see no connection to the real world. One way to avoid this dilemma is to use meaningful applications of mean, range, and standard deviation.

Understanding the concept is an important aspect of solving various physics problems. Understanding the concept will help in understanding the problems, determining problem-solving strategies, and using mathematics appropriately as a problem-solving tool. Lack of conceptual understanding results in the tendency to solve problems by relying solely on formulas without knowing the proper use of formulas according to the underlying concepts of the problem. Various problems related to rotational motion can be explained through the concept of torque. To solve the problem of torque, understanding the concept of torque and mastering the concept of vectors are needed to find solutions to the problems Many of the science teachers have a background in physics education. Science teachers who are a bachelor of physics education should master various physics concepts even though the material is not taught at the junior high school level. Therefore, the authors conducted research to determine the ability of science teachers with an education background in physics education in solving the problems of torque. The study involved 10 science teachers who teach in 10 different schools. This research was a descriptive study with data collection techniques in the form of a questionnaire using an essay question to test the science teacher's ability in solving the problems of torque. The results showed that most of the participants could not solve the problem of torque due to a lack of understanding of the concept in determining the torque generated by forces with various positions.
