The purpose of this study was to analyze the quality of the constructive play of 3, 4 and 5 year-old children. The researchers used unit blocks as the instrument because they are the most representative examples of constructive play materials. The subjects were 73 children enrolled in a half-day early childhood education program. The children's block play was videotaped 8 times, for a total of 330 minutes. The videotapes were transcribed and assessments were made on the children's 233 constructions in terms of the developmental stage of block play, the variety of materials used, play duration, and play intensity. The data were analyzed through two-way ANOVA to check age and sex differences. The results showed that children's developmental stages of block play were low on the average and that girls did not show an active interest in block play. The results also implied that block play developed by play experience rather than by age. Therefore, this study was interpreted to highlight the importance of teachers' understanding, planning, and mediation of block play in order to induce high-quality constructive play.

This study was purposed to discuss an educational concept of listening potential in ESL/EFL contexts as a counterpart of the reading potential concept in L1 contexts. As a preliminary condition for the concept of listening potential, this study investigated a relationship between reading and listening proficiency of ESL/EFL learners, focusing on roles of grammar knowledge in reading and listening comprehension. Reading and listening comprehension and grammar knowledge test scores of 231 Korean college students studying at a university in the U.S. were analyzed for this study. This study found that there was a positive correlation between reading proficiency and listening proficiency of Korean ESL college students. Grammar knowledge played significant roles accounting for reading and listening comprehension. Furthermore, this study found a difference between the reading proficiency and the listening proficiency across the stages of language development. However, results of this study did not empirically verify the concept of listening potential.

The purpose of this study was to develop a scientific inquiry model that makes scientific inquiry accessible to science teachers as well as students. To develop a scientific inquiry model, we investigated the research process demonstrated by ten scientists who were working at academic research institutions or industrial research institutions. We collected data through scientists' journal articles, lab meetings and seminars, and observation of their inquiry process. After we analyzed the scientists' inquiry strategies and processes of inquiry, we finally developed the Scientist's Methodology of Investigation Process model named SMIP. The SMIP model consists of four domains, 15 stages, and link questions, such as "if, why", and "how". The SMIP model stressed that inquiry process is a selective process rather than a linear or a circular process. Overall, these findings can have implication science educators in their attempt to design instruction to improve the scientific inquiry process.

This study was conducted to reduce sodium (Na) intake and to establish healthy dietary lifestyles of children. To achieve these goals, we searched, collected, and analyzed the materials related to the Na education, based on which the research personnel-professors and graduate students in nutrition and child education and elementary school teachers discussed to figure out major topics, objectives, and detailed contents and activities appropriate for Na intake reduction. Also a survey was done on the sodium intake and nutrition knowledge of the elementary students. We also organized an advisory committee composed of 15 professionals in related fields to discuss the adequacy and validity of the specific contents. Finally, we systematically organized the contents and developed children's textbooks and teacher's guidebooks. Considering the different cognitive development stages of junior and senior elementary students, we developed two different textbooks for each of them which are easy to read and understand, fun to play with lots of activities, and designed to practice into daily life. The contents cover three major topics-the concept of Na, Na in food, Na in life and are composed of 6 units in total. To help teachers understand and instruct, teacher's guidebook contains an overview of the education, specific information and practical guidelines for each class. We developed these education materials with the aim of lowering children's Na consumption and eventually promoting their health welfare; hopefully we expect these materials would be useful for children's nutritional education in the field.

The purpose of this study was to investigate the relative effect of individual-, parents-, and game-related variables on game addiction. Totally, 1065 10 to 18-year-olds participated and completed questionnaires. Male students had more tendency to game addition than female students. No difference in the level of addiction, however, was appeared among elementary, junior-high, and high school groups, which means that many young children are already Same-addicted. More severely addicted children and adolescents showed higher level of impulsivity, more difficulties in communication with their parents, and more expectation of psychological gratification and interpersonal relationship through the internet games. The relative effects of these independent variables to game addiction were different among gender*school groups. Firstly, impulsivity was significant only in boys of elementary group. Secondly, for the junior-high group, communication with father and mother was important to boys and girls, repectively. Lastly, expected gratification from gaming itself mainly predicted high school students' game addiction, irrespective of gender. The findings of this study suggest that earlier intervention to young garners should be carried out. It is also indicated that parents' and teachers' role for guidance of the internet games would be different with children's gender and developmental stages.

Purpose: To develop a tool to evaluate middle school sex education programs. Method: An evaluation tool was developed in 4 stages: first, preliminary items were developed based on the sex education guidebook for teachers published by the Korean Ministry of Education and Human Resources Development; second, a panel of specialists reduced the number of preliminary items by 3 validity tests on the contents; third, final items were selected from the results of pre-test. Finally, reliability and validity were tested by a sample of 601 middle school students of both genders attending all three grades. Result: The developed evaluation tool contained 31 items on the sexual knowledge and 22 items on the sexual attitude. The results of reliability tests were as follows: Cronbachs alpha for sexual knowledge was .84; and for sexual attitude was .88. Conclusion: This study suggested the developed evaluation tool for sex education programs for middle school students had a high degree of reliability and validity. Therefore, it can be utilized to effectively evaluate Korean middle school sex education programs.
