This study investigated the effects of small group drawing in learning the concepts of particulate nature of matter. Three classes of seventh graders (N = 126) at a coed middle school were randomly assigned to a pair drawing group, an individualistic drawing group, and a control group. The students were taught the 'three states of matter' and 'motion of molecules' for eight class periods. Prior to these classes, student self-efficacy, learning motivation, and attitude toward science instruction were examined. After instruction, tests assessing achievement, conception, learning motivation, and attitude toward science instruction were administered. Two-way ANCOVA results revealed that scores of achievement and conception for the pair drawing group were significantly higher than those for the control group. However, scores of the three groups did not significantly differ in learning motivation and attitude toward science instruction. Furthermore, no significant interactions surfaced between instruction and the level of self-efficacy in all dependent variables.

This study investigated the influences of role-playing analogy upon students' scientific conceptual understandings, application abilities, retentions of conception and application, and learning motivation. Four classes of 7th grade at a middle school in Seoul were assigned to control and treatment groups, and taught about 'motion of molecules' for 4 class hours. For the Treatment group, role-playing analogy instruction was used. The traditional instruction was used for the control group. Data analysis indicated that the scores of the treatment group were significantly higher than those of the control group in the tests on the conception, the retention of application, and the confidence. In the tests of the application, attention, and relevance, there were significant interactions between instruction and student' gender. Both female and male students in the treatment group scored significantly higher than those in the control group in the application test. In the case of attention and relevance tests, male students in the treatment group scored significantly higher than those in the control group. Educational implications are discussed.

In recent years, parents of students and government have been taking a growing interest in education for the gifted students and there are many research reports about the gifted education. Most of the reports, however, focuses on the conceptional feature of the gifted education program such as organization, operation, management, evaluation, etc,. In other words, there are very few researches on instructional materials for gifted students even though the materials is a critical factor for successful education programs. So, this paper introduces a lecture notes used in a personal education for gifted students to contribute in developing education contents in computer science area. The instructional materials titled as "The Necessity and Application of Matrix in Computer Science" is based on linear equation to usher the students into creative problem recognition and groping for solutions. Also, the instructional materials is useful for students to understand the tight mathematics-computer science relationship and the basic concept of liner algebra.

The purpose of this study was to analyse beginning science teachers' PCK. For the purpose of this study, two beginning science teachers were chosen in public middle school. Qualitative data were collected through classroom observation recording, semi-structured interviews, and other document data. Data were analysed using the constant comparative method. The results indicated that the two beginning science teachers' PCK had little differences; both have insufficient knowledge of science curriculum and assessment, and their PCK had quite differences in the instructional strategies and the orientations toward teaching science. Though they were aware of students' various levels, their common teaching method focused on delivery of science text knowledge for poor understanding about student. In conclusion, the two beginning teachers' PCK were still similar with preservice teachers. To develop beginning teachers' PCK, it needs to change the paradigm of pre-service teachers education program and to expand in-service teachers training and supporting program.

This study was conducted to develop the standard breakfast menu for those weak groups having insufficient breakfast intake. The following three target groups are classified as: 16-19 years old high school male student, 20-29 years old female who have job or college students, 20-29 years old male or female who have job (double income family). While developing menus for each target groups, we applied several basic guidelines for meal planning as follows: Nutrient intake level was set to $\graction one-Third$ of RDA, while the energy level to $\fraction one-quarter $ of RDAs. Most Sequent meal pattern of Koreans was adapted; Suitabilities of appropriate serving size and cost for middle-income families were considered; Domestic foods and ingredients were used. We developed 24 menus summed by 2 menus for each season and three target groups. When evaluating the menus, most of the breakfast menus were sufficient of nutrients as a meal for the subjects. Three food groups such as grain/starch group, meat/fish/egg/bean group, vegetable/fruit group were included in all menus. Even though milk/dairy products group was not excluded for some menus, other calcium substitutes like anchovies were used. Oil/nut/sugar group was used to a minimum. The average number of foods for each menu was 12.8, which ranged from 10 to 17 depending on the menus. The average weight of the menus including soup was 822 g, 633 g and 730 g for each target group, respectively. The average price of the menu ranged from 2,000 to 3,500 won per person. The above results could be applied at home as well as foodservice institutes and furthermore could offer information for developing breakfast-substituting food products.
