The purpose of this study was to examine (1) if sociocultural factors that are known to influence gender gap in mathematics achievement are gender equitable for Singaporean eighth grade students, (2) if there is a higher level of gender equitability in students' attitudes towards mathematics and (3) how sociocultural factors influence mathematics achievement for Singaporean eighth grade students. This study is based on 5,923 Singaporean eighth grade students who participated in TIMSS 2011 assessment. The study found that there were no statistically significant gender differences in 'parental involvement in education' and 'teacher efficacy.' There were no statistically significant gender differences in students' attitudes of 'like learning mathematics,' and 'value learning mathematics'. A significant gender difference was identified for the attitude of 'confident with mathematics.' The boys displayed a higher level of confidence in mathematics than the girls consistent with other study findings for Asian students. The degree of effect from 'parental involvement in education,' 'teacher efficacy,' and 'confident with mathematics' on mathematics achievement are found to be stronger for girls than boys. The finding implies that girls' mathematics achievement can benefit from having more positive encouragement and involvement of parents and teachers and strengthening confidence in mathematics.

This study investigates 628 high school students' math dislike tendencies by their math achievement levels. The findings show that, firstly, as the sample students' math achievement level decreases, the number of dislike factors increase. Secondly, students' math dislike factors are differentiated by their math achievement levels. Math high achievers show high math disliking tendency by teacher factor. Middle achievers show high math disliking tendency by complex application and relation factors. Low achievers show high math disliking tendency by comprehension factor. Finally the math disliking factors affecting the level of math achievement are influenced by schools and grades that students' attend. While math disliking factors such as comprehension factor, teacher factor, affection factor are generally present among sample schools, exceptionally JS high school students(high achieving students) are only affected by mentality factor. In addition, mentality factor affects the second grade students only. The implications of the study argue that students' math disliking tendencies could be systematically reduced by paying attention to such dependent variables students' achievement levels, grade, school characteristics, and independent variables including teacher, application, mentality, comprehension, and affection.

In this study, we investigate the effects of the methods of time allocation in lecturing on the mathematical academic achievement of freshmen in institute of technologies. The subjects are 392 freshmen from three universities participated in ABEEK(Accreditation Board for Engineering Education of Korea). They belong to three groups in accordance with the methods of time allocation in lecturing; 75 minutes twice a week(79 students) and 150 minutes continuously once a week(77 students) (university 1 of 156 students), 100 minutes twice a week(56 students) and 200 minutes continuously once a week(60 students) (university 2 of 116 students) and 50 minutes and 100 minutes separately once a week(62 students) and 150 minutes continuously once a week(58 students) (university 3 of 120 students). The results of this paper are summarized as follows: Firstly, the achievement of separate time-allocation groups is higher than that of continuous time-allocation groups. Secondly, the achievement of middle class students and low class students has higher effects when they are taught by using the methods of separate time-allocation in lecturing. Finally, the achievement of groups using 75 minutes twice a week is higher than that of using 50 minutes and 100 minutes separately once a week. In conclusion, this study suggests that the method of separate time allocation in lecturing using 75 minutes twice a week could be an advisable means to help those who achieve middle and low scores in the first college mathematics.

The former study results demonstrate that differences between people of creativity and non-creativity lie in differences of the self-efficacies rather than those of cognitive aspects and a man of higher self-efficacy has a tendency to set up a higher goal of achievement and higher self-efficacy influences his or her achievement results as well (Zimmerman & Bandura 1994). Using the method of mathematical creative responses of open-ended approach (Lee, Hwang & Seo 2003), difference of mathematical self-efficacies has been surveyed in the study. Results of the survey showed that some students of a high mathematical self-efficacy even had bad marks in the originality or creativity but, in some cases, some students of a low mathematical self-efficacy rather had good marks in the fluency. Therefore, the response results mathematical creativity ability may be a special ability and not just a combination of self-efficacy ability. The fluency of the mathematical creative ability may be a combination of mathematical motivation ability that have been surveyed in the study suggest that not only cognitive components but also social and emotional components should be included in a development process of new creative method for teaching and learning mathematics.

본 연구는 공간능력이 수학 성취도 및 STEM 분야의 성공에서 중요한 역할을 한다는 사실에 기초하여, 공과 대학생들의 공간능력, 수학 성취도, 그리고 언어 성취도 사이의 관계와 각 영역에서 성별 차이를 파악하는데 목적을 두었다. 그와 함께 수학 성취도에서의 성별 차이가 공간능력에서의 차이에 의해서 매개되는 지도 확인하고자 하였다. 이를 위하여 서울 소재 공과대학 신입생들에게 공간 시각화-회전(PSVT-R)검사를 실시한 후에 대학수학능력 시험의 수학 및 언어 영역과의 상관관계를 성별로 조사하였다. 연구 결과, 성별 차이는 공간 시각화 능력에서 가장 크게 나타났고, 다음이 언어 성취도, 그리고 수학 성취도의 순서로 낮아졌다. 남학생의 공간 시각화 능력이 여학생보다 0.8d(effect size) 정도 우수하였으며 남학생의 67%가 도달한 수준에 여학생은 34%가 속해있었다. 영역별 상관계수를 살펴보면 수학과 언어 성취도 사이에는 음의 상관관계가 존재하였다, 그러나 예측과는 다르게 수학 성취도와 공간 시각화 능력 사이의 상관관계는 작았다. 공간 시각화 능력과 언어 성취도 사이에도 상관관계는 존재하지 않았다. 그렇지만 공간 시각화 능력은 남학생보다는 여학생의 수학 성취도에 좀 더 강한 영향을 주는 것으로 나타났다. 그 이유는 남학생에서는 공간능력이 보편적인 현상이기 때문에 남학생 내에서는 공간능력이 수학 성취도에 별다른 영향을 미치지 않았던 것으로 파악된다. 그 외에도 공간능력이 낮은 집단에서도 수학 성취도에서는 성별차이가 나타나는 것을 확인하였다. 이것은 현 연구 집단에서는 공간능력이 수학 성취도를 결정하는 주된 요인은 아니라는 점을 보여준다. 언어 성취도가 수학 성취도와 음의 상관관계를 갖는 이유는 입시전형에 합격하기 위해서는 한 영역에서 낮은 점수를 받은 경우에 다른 영역의 점수는 상위권인 학생들이 지원한 결과로 해석된다. 마지막으로 공간 시각화와 언어 능력이 결합하여 수학 성취도에 미치는 영향을 살펴보았다. 언어 성취도와 공간 시각화 점수를 상위권과 하위권으로 구분한 다음 네 그룹으로 나누어서 수학 성취도를 비교하였다. 이 때 수학 성취도는 남학생, 여학생 모두에서 (1) 공간 상위권- 언어 하위권인 그룹, (2) 공간 하위권 - 언어 하위권인 그룹, (3) 공간 상위권 - 언어 상위권 그룹, (4) 공간 하위권 - 언어 상위권 그룹의 순서로 낮아졌다.

Since research has barely been done on the minority with low-achievement & low-SES in probability, this research attempted to search the change of their thinking level in the classes of probability and motivate them on the mathematical learning to feel confident in mathematics. We can say that the problems of the educational discriminations are due to the overlook on the individual conditions, situations, and environments. Therefore, in order to resolve some discrimination, 4 students who belonged to the minority group, engaged in the research, based on 10 units of the instructional materials designed for the research. As a result, for the student's thinking level, it was observed that they were improved from the 1st to the 3rd level in probability. Also, the researcher found that the adequate use of the encouragement, the praise, the direct explanation, and the scaffolding enabled them to prompt their learning motives and the increased responsibility on the learning. As time passed, the participants could share their mathematical knowledge and its concept with others, in the increased confidence.

This article provides how to implement the use of Realistic Mathematics Education (RME) in a teaching a function at a school to improve students' mathematization for their mathematical thinking using technology, This study was planed to get research results using the mixed methodology with quantitative and qualitative methodologies. 120 middle school students participated in the study to bring us data about their mathematical achievement and disposition. Through the data analysis used ANCOVA, the students with the experiment of the mathematization and technology excelled the other groups of students who were not provided with technology or both of them. In analysis of the questions of the achievement test, the problems for vertical mathematization were presented harder for the students than the other problems for horizontal and applicative mathematization. The technology environment might have helped students manipulate the application of real-life problems easier. This means that teachers can put more careful assignment on vertical mathematization using technology. We also explored that learning and teaching under RME using technology encouraged students to refine and develop their informal functional concept and pursue higher thinking of formalization. The study results in a lot of resources for teachers to use into their teaching mathematics for improving students' mathematical thinking.
