This study introduces the process and results of developing an adaptive math learning program for self-directed learning. It presented the process and results of developing an adaptive math learning program that takes into account the level of learners using artificial intelligence. We wanted to get some suggestions on developing programs for artificial intelligence-based mathematics. The program was developed as Math4U, an application based on smart devices in the "character and expression" area for 7th grade. The Application Math4U may be used differently depending on its purpose. It is also expected to be a useful tool for providing self-directed learning to students as the basis for educational research using smart devices in a changing educational environment.

The purpose of this action research project was to study the effects of incorporating coding into the middle school math classroom affected student dispositions with math and their understanding of mathematical concepts. The project, involving a total of 107 US middle school students, used five data sources to examine these effects: a survey, a chart measuring student engagement, a pre- and post-assessment before and after the coding project, and teacher observation with reflection forms. After analyzing the data, it was found that incorporating coding into the middle school math classroom could have a positive impact on student math dispositions and their understanding of math concepts.

The objective of this study was to evaluate the use of fuzzy math strategy to calculate variability and uncertainty in quantitative risk assessment. We compared the propagation of uncertainty using fuzzy math simulation with Monte Carlo simulation. The risk far Listeria monocytogenes contamination was estimated for carcass and processed pork by fuzzy math and Monte Carlo simulations, respectively. The data used in these simulations were taken from a recent report on pork production. In carcass, the mean values for the risk from fuzzy math and Monte Carlo simulations were -4.393 log $CFU/cm^2$ and -4.589 log $CFU/cm^2$, respectively; in processed pork, they were -4.185 log $CFU/cm^2$ and -4.466 log $CFU/cm^2$ respectively. The distribution of values obtained using the fuzzy math simulation included all of the results obtained using the Monte Carlo simulation. Consequently, fuzzy math simulation was found to be a good alternative to Monte Carlo simulation in quantitative risk assessment of pork production.

The constituents of math learning styles are information recognition and information processing in the cognitive domain and attitudes toward math learning and environments of math learning in the affective domain. Each of the constituents has two opposing styles; there are the visual style and verbal style in information recognition; and there are the whole style and analytical style in information processing. And as for attitudes toward math learning, there are two styles which are the authoritative and goal-oriented style and the practical and entertaining style. Also as for attitudes toward environments of math learning, there are two styles which are the interior-oriented style and exterior-oriented style. There can be classified into 16 types of mathematics learning by the combination of a total of 8 styles of mathematics learning. The purpose of this study was to analyze the preference of the students from three middle schools located in Daegu Metropolitan City to the styles and types of mathematics learning.

This study was conducted to analyze the effects of mathematics classes using engineering tools on students' mathematics academic achievement and mathematics learning attitude, focusing on the basic figure and drawing sections of the first grade of middle school. Eighty students of first-grade at H Middle School in South Gyeongsang province were divided into two groups, taking a total of six weeks of classes using engineering tools(Algeomath) and traditional tools, and covariate analysis(ANCOVA) was used to analyze students' mathematics academic achievements and changes in mathematical learning attitude. The analysis found that classes using engineering tools were effective in students' mathematics academic achievements and attitude of learning math. Based on the results of the study, the necessity of utilizing various engineering tools in the future secondary school math class and the prospect and implications of the classes were discussed.

The benefits of teaching learning materials to others have been shown on learning achievement. Anxiety is one of the obstacles in learning and it has been shown that math anxiety is strongly associated with math achievement. Thus, the aim of this study was to investigate whether teaching others benefits math anxiety when university students learn statistics. 59 students who enrolled in statistics class participated and 30 students performed group assignment of teaching peer in a group and 29 students did not. Other than group assignments, the instructor, lectures, assignment of solving the problems, and exams were all the same. The results showed that the math anxiety of students who did group assignments of teaching was decreased at the end the semester. Increased math anxiety yielded negative attitudes toward learning statistics, resulting in poor learning performance. Furthermore, the relationship between math anxiety and the attitudes toward leaning statistics was moderated by teaching others. The results suggest that teaching others has an effect on reducing math anxiety and thus, possibly yield persistent learning gains.

This study suggests effects and procedure of G-Learning math class which had implemented toward a class of K-5 for 6 weeks in La Ballona elementary school located in Culver City, LA in USA. For designing G-Learning math class, developing the G-Learning contents, constructing teaching and learning model, publishing the teacher and student's book and conducting teacher training were carried out. As for the results, the achievement score of G-Learning class rose 12 points which marked higher improvement than the compare class. Also in G-Learning class, the score of 1/3 lower achievement group increased 22 points and 1/3 higher achievement group rose 9 points with statistical significance. Moreover, after G-Learning math class, interest and awareness to effectiveness toward G-Learning math was positively increased.

In this research, we investigated the effect of arithmetic learning utilizing mathematical mobile application on arithmetic fluency and learning motivation of underachieving students in math. 24 4th grade math underachievers were divided into control and experimental groups. Arithmetic learning utilizing mathematical mobile application was conducted for experimental group and arithmetic learning utilizing learning worksheets was conducted for comparative group. After three weeks, the experimental group showed increase in math fluency and motivation compared to control group. Implications are discussed.

The purpose of the study was to develop project based math learning using future prospective jobs to find out its effects on elementary school student's attitude toward mathematics and career awareness. Also, this study aims at implementation of this project based math learning program in school math education. The project based math learning using future prospective jobs was conducted through 19 lessons for 7 weeks. As a result, the project based math learning using prospective jobs is turned out to be effective on developing attitudes on mathematics and career awareness positively.
