  • Technological development, a diverse range of media adapting to new technology has been developing. Augmented Reality Technology provides realistic information through the stereoscopic 3D images and it has been riding a wave of learner interest as an educational media which can broaden their learning experience through direct operating activity. The biggest reason why the Augmented Reality has gained such attention is because of its unique way of suggesting learning information that unlike the existing educational media, the Augmented Reality provides additional digitalized information while its users are looking at the actual object. Based on the domestic and foreign cases of development for educational contents using the Augmented Reality Technology, this thesis suggests the utilization of Pop-up books and multi-augmented Digilog Books that are ways to maximize the educational effects of the Augmented Reality. Through the development of smartphone applications that are propagating lately at a rapid rate, users can now use the Augmented Reality educational contents in a way that is easier than ever.

  • With the enlargement of school meals, the lunch program has played an important role in educating young students about good eating habits and food Preferences. The objective of this study was to investigate the awareness and preference of vegetables and to provide preliminary data required for framing a menu of school meals to help students maintain good food preference and eating habits with a balanced food diet. A survey was conducted from 25th October to 27th November, 2004 with 873 elementary school students (M: 474, F:399) in the 4th, 5th, or 6th grade of 6 schools in Daegu and Gyeong sang but do (Yongchon, Gumi, Pohang). Satisfaction for the school meal was rated by $52\%$ of the students and 'rice and soup' was the favorite meal type. Eating habits of students were not influenced by the employment status of their mothers. Only $11.2\%$ of students selected vegetable as their favorite food. Marsh mallow, taro stem, green bean sprouts, crown daisy and broccoli showed very low awareness and were selected as the least favorite vegetables. The most important criteria of preference were the taste and eating experience of the vegetables. The most preferred cooking method of the vegetables was tchigae which is a simple stew. Recognition of frequency for daily eating vegetables significantly affected the real intake of vegetables for everyday meals and the preference of vegetables also significantly affected the vegetable intake from the school meals. Compared to the school dietitian, mothers showed a greater frequency in being selecting as an educator of nutritional information. The above results indicated the need to improve the level of students' understanding of the importance of vegetables in the daily diet with parental education and publicity.

  • This study was conducted to evaluate the sanitary performance and education of elementary and middle school food service employees, by administering questionnaires to 358 elementary school food service employees and 171 middle school food service employees in Seoul. The collected data were subjected to descriptive analysis and $X^2$ tests using the SPSS package program. On the questionnaire, items pertaining to personal hygiene, ingredient control, process control, safety management, and sanitation education were used to measure sanitary performance, with a maximum possible rating of 5 per each category. The results can be summarized as follows. Elementary school food service employees' had the following sanitary performances scores: personal hygiene(4.75), ingredient control(4.82), process control(4.73), safety management(4.69) and sanitation education(4.29). Middle school food service employees' had the following performance ratings: personal hygiene(4.62), ingredient control(4.71), process control(4.71), safety management(4.61) and sanitation education(4.05). In the elementary school employees, 59.8% received regular sanitation education once per month, while 67.3% of middle school employees received regular sanitation education more than once per month. At the elementary schools, food service sanitation education was conducted verbally(39.4%), while middle school sanitation education was principally carried out through the distribution of leaflets(41.5%). The average effectiveness scores for food service verbal education were 2.97 out of a possible 5 at the elementary schools and 2.94 out of 5 at the middle schools. In both elementary and middle schools, the majority of the employees attributed the low level of sanitation knowledge in food service to a lack of facilities and equipment.

  • Recently, 3S Mathematics Education (Storytelling mathematics education, SMART mathematics education, and STEAM mathematics education) is emphasized. Based on recently published report on Storytelling mathematics textbook, we propose executable expression based SMART storytelling mathematics related to the elementary mathematic curriculum on 3D building blocks. We designed letters and expressions to represent three dimensional shape of 3D building blocks, and we compare its characteristics with that of LEGO blocks. We assert that text-based executable expressions not only construct what students want to make but also teachers can read students thinking process and can support educational help based on students needs. We also present linear function, quadratic function, and function variable concepts using executable expressions based on 3D building block as an example of SMART storytelling mathematics. This research was supported by the collaborated creativity mentoring project between Siheung City and college of education at Seoul National University. We hope designed executable expressions can be used for the development of SMART storytelling mathematics education.

  • This study aims to compare the word decoding skills, phonological awareness (PA), rapid automatized naming (RAN) skills, and letter knowledge of first graders with developmental dyslexia (DD) and those who were typically developing (TD). Eighteen children with DD and eighteen TD children, matched by nonverbal intelligence and discourse ability, participated in the study. Word decoding of Korean language-based reading assessment(Pae et al., 2015) was conducted. Phoneme-grapheme correspondent words were analyzed according to whether the word has meaning, whether the syllable has a final consonant, and the position of the grapheme in the syllable. Letter knowledge asked about the names and sounds of 12 consonants and 6 vowels. The children's PA of word, syllable, body-coda, and phoneme blending was tested. Object and letter RAN was measured in seconds. The decoding difficulty of non-words was more noticeable in the DD group than in the TD one. The TD children read the syllable initial and syllable final position with 99% correctness. Children with DD read with 80% and 82% correctness, respectively. In addition, the DD group had more difficulty in decoding words with two patchims when compared with the TD one. The DD group read only 57% of words with two patchims correctly, while the TD one read 91% correctly. There were significant differences in body-coda PA, phoneme level PA, letter RAN, object RAN, and letter-sound knowledge between the two groups. This study confirms the existence of Korean developmental dyslexics, and the urgent need for the inclusion of a Korean-specific phonics approach in the education system.
