This study aims at identifying the effect of problem posing on the academic achievement in high school mathematics. As subjects of the study, two classes of first grade in high school were selected. One of them was treated with problem posing learning, the other was treated with learning-in-a-body. Each has 40 students and was also divided into two groups(high- level and low-level) according to their learning-level. Two instruments were used for this study. One was the teaching-learning method developed by the researcher. The other was TTCT(Torrance Test of Creative Thinking). The 't-test' was used for this study and the significant level of test was within 5 percent. The results of this study are as follows: 1. The group with problem posing learning showed significantly higher academic achievement(learning-ability) than the one with learning-in-a-body. 2. There was no significant difference in the academic achievement(creativity) between the two groups. But there was significant difference in the creative factors. 3. There was no significant differences in the academic achievement between high-level-groups in each group. 4. There was significant difference in the academic achievement (learning-ability) between low-level groups in each group. And there was significant difference in the creative factors. On the basis of the results above, the following conclusions could be made. The problem posing learning method was more effective in the academic achievement in highschool mathematics than learning-in-a-body. Especially low-level group was more effective than high-level group. These facts implies that it is more effective for a teacher to adopt the problem posing learning considering the students' learning-levels.

Mathematical, verbal, and spatial abilities are known as three important indicators for the success in the STEM disciplines. In this study, Purdue Spatial Visualization Test-Rotation, College Entrance Scholastic Aptitude Test- Math and Verbal score of engineering freshmen students have been used to find the relationships among these areas. In addition, gender differences in spatial visualization, verbal achievement and mathematical achievement have been investigated, too. In this research, I found that gender difference was highest in spatial visualization ability, followed by verbal achievement and smallest in mathematical achievement. Substantial number of male students possess high level of spatial abilities, but only half of female students were at the same level where their male colleagues were. The correlation between spatial ability and mathematical ability was negligible, contrary to former researches on elementary and middle school students. But the correlation was stronger for female students than male students. The correlation between mathematical achievement and verbal achievement was negative. It reflects the fact that when one section of SAT score is low, score of other sections should be higher to get admitted to college. Gender difference in mathematics was smallest for high achieving spatial ability group. For low spatial ability group gender difference in mathematics achievement has been observed, too. To find the combined contribution of spatial and verbal abilities to mathematics achievement, students were divided into 4 ability groups. Mathematics achievement decreased in the order of (1) high spatial -low verbal group, (2) low spatial - low verbal group, (3) high spatial - high verbal group, (4) low spatial - high verbal group.

This study was carried out to investigate the difference of gender of academic self-efficacy, external motivation, interest and science achievement for high school students of Korea and to verify the structural relationship among these variables using PISA 2006 data. The major findings of this study are as follows. According to Multi-group analysis, Latent means analysis (LMA), where boys were used as the reference group, girls showed lower latent mean values on the academic self-efficacy, extrinsic motivation and interest. Academic self-efficacy was found to have a greater effect on achievement compared to external motivation and interest. According to structural equation modeling (SEM) analysis, academic self-efficacy and extrinsic motivation affected interest. Academic selfefficacy, external motivation, and interest affected science achievement. Lastly, interest mediated academic selfefficacy and external motivation on science achievement.

This study examined the effects of the learning cycle model by learner's characteristics such as I.Q., cognitive levels, inquiry skins, cognitive style, activity, reflectiveness. To see the effects of the learning cycle model, nonequivalent control group pretest-posttest multiple treatment designs was used in the study. 99 middle school second-graders(female) were divided into two groups. One group was selected as the experimental group (n=50), the other served at the comparison group(n=49). During the eight-month period, the students in the experimental group were instructed according to the learning cycle model, while the students in the comparison group were instructed according to the traditional instruction methods. Achievement data from science achievement test were analyzed by an ANOVA technique. The results of the study are as follows : 1. Science knowledge achievement. For the lower level students of activity, the learning cycle model is superior to the traditional approaches in science knowledge achievement. 2. Science inquiry skills. For the upper level students of I.Q., cognitive levels, inquiry skills, cognitive style and reflectiveness, the learning cycle model is superior to the traditional approaches in science inquiry skills. 3. Attitudes toward science. For the lower level students of I.Q., cognitive levels, inquiry skills, cognitive style, activity and reflectiveness, the learning cycle model is superior to the traditional approaches in attitudes toward science.

The purpose of this study was to examine group differences in paternal behaviors (i.e., paternal connection, paternal punitiveness, and paternal knowledge) within and across three academic achievement levels-low, moderate, and high, and to explore the effects of paternal behaviors on the academic motivation of Chinese adolescents within these three achievement groups. Analyses of variance (ANOVAs) indicated that adolescents with low achievement perceived their fathers as more punitive than teens with moderate and high academic achievement. Regression analyses also revealed that paternal punitiveness (negative) and paternal knowledge (positive) were significant predictors of academic motivation for teens with low levels of academic achievement; while paternal punitiveness was a significant negative predictor of academic motivation among adolescents with moderate achievement. In contrast, for adolescents with high achievement, paternal connection was a positive significant predictor of academic motivation. The present findings provide some evidence that the impact of parental behaviors on teen's motivation varies across adolescent academic achievement levels, which may prove useful for professionals working with fathers to help target the most effective parenting behaviors to foster academic motivation.

Objectives: The purpose of this study was to examine whether demographic and socio-economic characteristics, health behaviors and health status are related to academic achievement in Korean adolescents. Methods: Data from the 14th Korea Youth Risk Behaviors web-based Survey(KYRBWS) administered in 2018 were analyzed; 60,040 students in middle and high school participated in the survey. It was conducted frequency analysis, Rao-Scott chi-square test and multiple logistic regression analysis after adjusted for variables such as age, school grade. Results: The significant influencing factors on academic achievement were family economic status, living with parents, subjective health status, smoking experience, alcohol use experience, eating breakfast, sleeping, internet use during weekdays, depressive symptom(p<.001). The odds ratio for achieving higher academic achievement compared with those who never smoked was 1.50(p<.001). Conclusion: I found that students' undesirable health behaviors affect their academic performance. To improve academic achievement, I recommend intervention programmes such as school health promotion that reduce undesirable health related behaviors.

The purpose of this study was to examine the effects of experimental learning using Small-Scale Chemistry (SSC) on science achievement and scientific attitude of high school students. SSC experiments were devised for 5 experiment themes of high school science textbook. Two classes were chosen from a high school in Busan and adopted into the comparison group and the experimental group; one group with thirty-four students participated in the class with an experimental learning using the SSC (experimental group), and another group with thirty-seven students participated in the class with the traditional learning (comparison group). The major discoveries of this study were as follows: Experimental learning using SSC has shown a significant difference between two groups in the science achievement of the students. Also there was a statistical difference between these two groups in the test which was conducted after a month to find out the durability of the experiment. Thus, the learning using SSC is assumed to be durable. Furthermore, there was a significant difference in scientific attitude between the two groups. It seemed that the learning using SSC had a good influence on fanning students' scientific attitude. In conclusion, an experimental learning using SSC has a positive effect on scientific achievement, the durability and scientific attitude of the students. We hope to develop suitable and various experimental learning materials using the SSC program that can be adopted in the classroom soon.

The purpose of this study is to examine whether the visual materials presented in the science textbooks coincide with those visual materials that are preferred the most by students. After analyzing the visual materials presented in the unit "Molecular Motion and Change of State" of science textbooks for the first grade of middle school, questionnaires by teaching-learning process are made. Thereafter, students are requested to select those types of visual materials that were preferred by them by process and describe their reasons for the selection. According to the results of the survey of students' perception, students at the high science achievement level prefer those visual materials that were presented conceptually and implicatively, while students at the low science achievement level prefer concrete and detailed visual materials. Except for the learning motivation process, the proportion of non-preferred visual materials is higher in the remaining processes and those visual materials that were presented in the science textbooks are much different from those visual materials that were preferred by students.
