This research analyses spatial and temporal characteristics of the academic performances of high school students by using all 2,065,166 SAT scores for 3 years. The spatial inequalities in Seoul are analysed by DBMS and GIS. Based on three-year raw data of Korean SAT scores, the spatial and temporal characteristics of academic performances are scrutinized: 868,029 SAT scores cases of 2000 academic year on Novemver 17, 1999, 609,258 cases in 2005 academic year on November 17, 2004 and 587,890 cases in 2009 on November 13. The result shows that there are significant spatial disparities of the level of academic performance in Seoul by Gu level, also indicating that the disparities are getting wider over the course of time. The widening disparities by Gu level means that educational spatial inequality is intensified in spite of the increasing overall trend of academic performance of Seoul. It is also notable that disparities between regions are distinctive, while those in regions are not significant and sustained constant as time flows.

The purpose of this study was to compare the perception of meals and nutrition knowledge among high school students in Seoul. A survey was carried out on 548 male/female students in general and vocational high schools. The general high school students showed higher frequency of breakfast than the vocational high school students (p<0.001). As for the reasons for eating alone, the general high school students showed high frequency of 'busy', whereas the vocational high school students revealed high frequency of 'irregular meal times' (p<0.001). Concerning the habit of eating alone, 'irregular meal times (25.0%)', 'unbalanced diet (22.4%)', and 'instant food (16.6%)' were observed in that order (p<0.01). The percentage of high school students who regarded family meals as meals eaten with every member of their family was 70.6% (p<0.05). The percentage of general high school students who ate family meals was 61.8% and that of vocational high school students was 50.0% (p<0.01). When agreement with attitudes, environment, and participation in family meals was evaluated using a Likert scale (strongly agree 5 points, strongly disagree 1 point), the general high school students showed a higher level of agreement than the vocational high school students, and the results showed a significantly higher level of agreement as the frequency of family meals increased. Likewise, the groups who scored a higher level of nutrition knowledge had positive attitudes, environment, and participation in family meals with significant differences.

This study analyzed the gap in perception between communication with parents and filial piety according to the general characteristics of teenagers. The test subjects were high school students from academic and vocational school from different districts of Seoul. A survey was conducted from March to July of 2014 to 290 high school students. Data analysis was conducted on the SPSSWIN 18.0 program using a t-test, one-way analysis of variance, correlation analysis, and other tests. The empirical analysis of the experiments were verified at the significance level of 5%. First, communication with fathers differed significantly depending on the school division, economic class, religion; and communication with mothers differed significantly depending on school division, grade-level, academic performance, domestic discipline, and economic class. Second, the perception of filial piety showed a significant positive correlation with the communication with the mother; and with the communication with the father. The implication of this study is that better communication between the parents and teenagers correlate with the higher filial piety according to the general characteristics of teenagers, and should become a central material for policy.

This study investigated the effects of grouping method in solving chemistry problems using Think-Aloud Paired Problem Solving (TAPPS). Three classes (125 students) of a co-ed high school in Seoul were randomly assigned to the control, the homogeneous TAPPS, and the heterogeneous TAPPS groups. Prior to the instructions, a test of awareness of metacognition was administered. In the treatment groups, students were grouped into either homogeneous or heterogeneous group on the basis of their pre-achievement levels, and worked in pairs on chemistry problems about chemical equation and stoichiometry. Students' analytical skill, problem solving ability, and awareness of metacognition were examined after the instructions. One-way ANCOVA results indicated that the scores of the homogeneous TAPPS group in the analytical skill test were significantly higher than those of the heterogeneous TAPPS group. However, there were no significant differences among the three groups in the problem solving ability and the awareness of metacognition.

Problem solving ability, having been thought as one of the most important goals of science education is also a primary task for the current education. Indeed, the students' problem solving ability has shown almost no actual progress, despite our long accumulated science education. Under this circumstances, cooperative learning, a way to grow students' positive inter-dependence and problem solving ability in the basis of their active participation and discussion, was proposed as an effective teaching method. But, results have not consistently shown the advantage of cooperative learning over traditional learning for promoting academic achievement in science. Studies have consistently shown greater effectiveness on affective aspects. But, relatively few have focused on biology in Korea. The purpose of this study was to examine the effects of cooperative learning on the achievement and attitude of high school biology students. The pretest-posttest control group design was applied. The sample consisted of 50 11th-grade female students in experimental group(cooperative learning Student Team Achievement Division model) and 50 students in control group(traditional learning). Students in both groups recieved identical content instruction on the unit 'II. Methabolism'. These groups were treated for 13 hours during 5 weeks. Achievement data were collected using a 24-item multiple-choice test(content validity= .85). Science attitude was measured by an instrument which adapted by Kim In Hee(1994). The instrument(Cronbach $\alpha$=.89) included 40 items in four subscales: attitude toward science, social meaning of science, attitude toward science class, and scientific attitude. An analysis of covariance (ANCOVA) was used as the data analysis procedure. For the achievement data, no significant difference exists between the cooperative and traditional groups (p> .05). But, cooperative learning was effective in low-ability students(p < .05). For the science learning attitude data, cooperative learning was more effective than the traditional one(p< .05). Students in the cooperative group acheived better than those in traditional one especially in the subscale of attitude toward science class. There was no meaningful difference of the two methods in both high and average ability students, while cooperative learning was more effective than the traditional one in low ability students(p<.05).

In this study, we investigated the characteristics of inquiry problems set by high school students who observed an 'unexpected phenomenon' and identified the effects of providing scientific information on setting inquiry problems. The subjects of this study were 126 eleventh grade students in Seoul that were randomly assigned to group A (N=66) and group B (N=60). In the study, watching a video of about 45 seconds of the unexpected phenomenon repeatedly for 20 minutes, all the students freely wrote inquiry problems that they wanted to carry out in their handouts. At this time, it is characterized that only the handout of group B additionally included scientific information on the unexpected phenomenon. As a result of the study, students, regardless of group, set more 'curiosity-oriented inquiry problems (i.e., focusing on inquiries they want to do rather than revealing what might be the cause of the phenomenon)' rather than going into a 'cause-oriented inquiry problem solving (i.e., revealing the cause of the phenomenon).' Among the curiosity-oriented inquiry problems, most of them were 'new-result inquiry problems (i.e., investigating what new results will occur by simply manipulating experimental situations).' It was also found that students who were provided with the scientific information tended to set significantly more inquiry problems using the provided information than those who were not (χ2(1)=8.996, p<.01), nevertheless the students with the scientific information did not set significantly more cause-oriented inquiry problems (χ2(1)=1.376, p>.05). The findings have been discussed from the four perspectives (i.e., lack of provided information, lack of opportunities to internalize the provided information, personal curiosity-seeking, and intuitive thinking), and implications for inquiry problem setting were suggested.
