The purpose of this study was to investigate the effects of using graphing calculators on students' understanding of the linear and quadratic function concepts. The populators of this study are tenth graders at high school in Seoul, one class for the treatment group and another class for the comparison group, and experiment period is 14 weeks including two weeks for school regular exams.Function tests used in the study was proposed which described a conceptual knowledge of functions in terms of the following components: a) Conceptual understanding, b) Interpreting a function in terms of a verbal experission, c) Translating between different representations of functions, and d) Mathematical modeling a real-world situation using functions. Even though the group test means of the individual components of conceptual understanding, interpreting, translating, mathematical modeling did not differ significantly, there is evidence that the two groups differed in their performance on conceptual understanding. It was shown that students learned algebra using graphing calculators view graphs more globally. The attitude survey assessed students' attitudes and perceptions about the value of mathematics, the usefulness of graphs in mathematics, mathematical confidence, mathematics anxiety, and their feelings about calculators. The overall t-test was not statistically significant, but the students in the treatment group showed significantly different levels of anxiety toward mathematics.

Motivation for learning is important for positive learning outcomes as well as for measured achievement levels. When students come to our classes, they bring with them learning histories in which we as individual teachers, most likely, did not have an input. Our students do not only bring with them different levels of prerequisite leanings but also different levels of affect for what they will be learning. If we leave their final learning at the mercy of these entry characteristics, a test given the first day before the course will have almost isomorphic results with their achievement levels on the last day. The ones who had 'it' on the first day will be the ones who in the future will also have 'it', not too different from what the present situation is all over the world. These circumstances will tend to be the case ad infinitum, unless of course, we want to change the situation. This research clearly shows that effective instructional methodologies coupled with cooperative peer interactions not only have an impact on achievement but also on positive attitudes toward one's learning.

Social awareness of mathematics and academic attitudes toward the value of mathematics education has kept changing according to the intellectual, political and religious contexts. In this article, we examine how mathematics was defined and recognized in liberal arts education of the Roman Empire and early medieval Western Europe. This study analyzes how mathematics was described in encyclopedic works written in the Roman era after the mid-second century BC and in the Western European monasteries and cathedral schools after the fifth century. Ancient Greek mathematics took a clear place in liberal arts education through encyclopedia writings and prepared a mathematics curriculum for medieval universities. I hope this study will contribute to understanding the origin and context of the mathematics curriculum of medieval universities.

수학교과의 특성상 많은 학생들이 수학 학습에 어려움을 느끼고 있으며 훌륭한 교수 학습 방법이 제시되고 있지만 실제 수학 학습 부진아는 줄어들지 않고 오히려 더 많아지는 것이다. 본 연구는 마인드 맵을 적용했을 때 학습부진아들의 수학 학업 성취와 태도에 어느 정도의 긍정적인 영향을 미치는가에 대해 알아보고자 한다. 이를 위해 충남에 소재하고 있는 C고등학교 1학년 2개 학급 32명의 학습부진아들을 대상으로 사전 수학학습능력검사, 사전 사후 수학태도 설문조사, 사후 수학 학습능력 검사를 실시하였다. 본 연구 결과를 통하여 학습 부진아들의 수학 학습에서의 태도와 수학 학습능력 향상에 마인드 맵을 활용한 수업이 긍정적인 효과를 줄 것으로 예상하였으나 검증결과 유의미한 효과를 나타내지 못하였다. 그러나 마인드 맵을 수학 학습에 활용하는 것과 이의 활용이 학습태도 변화에 긍정적인 영향을 주었음을 알 수 있다. 따라서 학습 부진아에 대한 특성을 먼저 파악한 후 그에 맞는 마인드 맵을 교수 학습에 적용해야하며 학생들이 이 마인드맵을 바르게 인식하고 익숙하게 작성할 수 있도록 충분한 시간적 여유가 제공되어야 한다. 교사의 전문적 지식과 학생에 대한 교사의 배려 속에서 마인드 맵에 대한 후속연구가 장기간에 걸쳐 체계적으로 진행된다면 좋은 효과를 기대할 수 있을 것이다.

The purpose of the study was to investigate the effectiveness of the manipulatives in instruction of mathematics to those who have learning disabilities. Two middle school students who revealed very low achievements in the previous mathematics tests were involved in this study. Unit Cubes were used as the manipulatives, and the researchers utilized this manipulatives to teach the number bases. After a series of instructions utilizing the Unit Cubes, the subjects were interviewed with semi-structured form. In general, the effect of using the manipulatives were positive. Both subjects could understand much better with the Unit Cubes, and revealed affirmative results such as their positive attitudes toward mathematics.

The instructional influences of cooperative learning strategies, which emphasize mutual interdependency of learners, group goal, and individual accountability, upon students' achievement, the attitude toward science instruction and the perception of learning environment were investigated. Before instruction, the prior knowledge test about atoms and molecules, the test of attitudes toward science instruction, and the perception questionnaire of learning environment were administered, and the grade in the previous mathematics course was obtained. These scores were used as covariates. Mid-term examination score was used as blocking variable. For instruction, three different strategies-traditional individual learning, small group learning, and cooperative learning-were used and teaching materials for the units of mole and stoichiometry were also prepared. After instruction, the researcher-made achievement test, the test of attitudes toward science instruction, and the perception questionnaire of learning environment were administered. The perception questionnaire of group activities was also administered to the two treatment groups. In the quantitative subtest, the scores of cooperative learning group and small group learning group were significantly higher than those of traditional individual learning group. However, the cooperative learning group's scores in the achievement test and the qualitative subtest were significantly higher than those of small group learning group and traditional individual learning group. The students in the cooperative learning group were found to have the most positive perception of learning environment but to have similar attitudes toward science instruction. No interaction between the treatment and the level of the previous achievement was found in any of the analyses. In the perception questionnaire of group activities, students in both small group learning group and cooperative learning group exhibited positive perception of group activities. However, students in the cooperative learning group tended to think that their activities were related with their group's success. Educational implications are discussed.

This study explores the impact of a STEM integration teacher professional development program focusing on teachers' perception of engineering and their attitudes toward integrating engineering into teaching. A total of sixty-eight teachers from ten schools participated in the program for five days. Data are collected from three main sources including (1) pre and post concept maps probing teachers' perceptions about the engineering discipline, (2) a pre and post survey measuring teachers' self-efficacy of teaching science/mathematics within the engineering context, and (3) engineering integrated science and (or) mathematics lesson plans and teaching reflections. This study utilizes both qualitative and quantitative research methods depending on the data we have collected. The results show that both science and math teachers thought that integrating engineering into teaching provided valuable outcomes, i.e., promoting students' learning about engineering and improving their interest in science or math through real-world problem solving exercises. Participants also felt more comfortable about integrating engineering in their teaching after the program. The results also imply that the teachers' understandings of engineering become more concrete after the program. This study also provides an overview of the challenges and advantages of teaching engineering in K-12 science and mathematics classrooms.
