This paper examined vocabulary in elementary mathematics textbooks and workbooks for the grade band of 3~4. This study focused on the adequacy of vocabulary using 9-degree of semantic difficulty. The results of this study showed that about three to eight percent of vocabulary with difficulty for students in grades 3~4 was employed. Whereas some difficult vocabularies were used along with the picture that helps students understand their meanings, others were presented without any illustrative tools. The most frequent vocabularies in the main activities of the mathematics textbooks included 'investigate', 'represent', 'number', 'how many', and 'method'. Based on these results, this study provides textbook writers with implications on what to further consider in dealing with vocabulary in instructional materials.

By PISA 2007, TIMSS 2011, Korean high school students had high academic achievement to science and mathematics, while they had low attitude. Prospective college students are increasingly avoiding natural science and engineering. Moreover, the opportunities to learn to computer science in middle and high school are disappeared rapidly. The necessity of STEAM program based on Physical computing arise under these situation. Therefore, we developed STEAM program and studied the effects of the program in 2012. The result showed that students' scientific interests and attitude, scientific problem solving ability, scientific creative problem solving ability, personality test for children, and satisfaction of school life were enhanced. This study is follow-up study for the same students who improved every domain of the measurements. They were administerd pre-test at start of 2012, post-test at end of 2012, and delayed post-test at the end of 2013, on same test. The result of the study showed that only attitude to Scientific Inquiry was enhanced, but there was no significant result on the other domain of the test in comparison with start of 2012. But this result demonstrate the effect of STEAM education conversely.

This study was conducted to analyze recognition, applicability, class satisfaction, and needs as well as students' attitudes for eating behavior by 1st and 3rd graders of a mixed middle school located in Gyeonggi area in relation to food and nutrition section of the Technology and Home Economics curriculum and thereby provide basic data for development of strategies of educational effect maximization of food and nutrition in the curriculum. 522 questionnaire were collected and statistically processed. Findings from this study are as follows. Both 1st and 3rd graders were found to exhibit relatively low preference for technology and home economics curriculum. While 1st graders were more interested in the subject than 3rd graders, the frequency of practical use of the food and nutrition section in every day life was higher in 3rd graders than that in 1st graders. For food and nutrition section of the subject, preference level of the 1st graders was higher than 3rd graders. The 1st graders were higher than 3rd graders in the needs for food and nutrition section as well as in usefulness in every day life of the unit. The applicability in every day life of the unit was found to be generally higher, with 1st graders having a higher level of applicability than 3rd graders (p<0.001). Class satisfaction of the unit was higher in 1st graders than 3rd graders, with the most satisfactory unit being 'basics and practice of cooking' both for 1st and 3rd graders. Needs for food and nutrition unit were higher in 1st graders than 3rd graders, with the unit highly needed being 'basics and practice of cooking' both for 1st and 3rd graders. Regarding interrelation of the degree of preference, need, applicability and class satisfaction, as the preference was high on food and nutrition, the degree of need, applicability, and class satisfaction was high. As respondents recognized food nutrition section necessary, they were more satisfied and showed high applicability for the section. Therefore, contents of food and nutrition section should be improved with re-organization of educational and subject contents so that they will be best fit for students by grade, to increase preference, applicability and necessity in every life. In addition, to maximize the applicability of the subject in everyday life, sufficient class-time should be assigned for the purpose of experiment- and practice-based education, and a wide range of teaching strategies are needed to increase students' interest in the subject.

This study has examined 5-year students in the kindergarten and students in the 2nd, 4th, and 6th grade in the primary school to analyze their perceptions about scientists. science, and how they apply science in their daily lives. First, students have 4 stereotypic images on scientists, specifically in 'indoor', 'male', 'lab coat'. and 'scientific instrument'. There were significant differences in stereotypic images on scientists depending on genders and ages. Girls and primary students showed higher scores than boys and kindergarten students did. respectively, in stereotypic images on scientists. No differences were observed for the stereotypic images on scientists among primary students, regardless of their grades. Second, most of students were interested in science. Depending on grades, there were significant differences in their preference for science. Students in higher grades showed lower scores than those in lower grades did. In addition, only a few of them hoped to be a scientist in the future. Boys showed higher scores in their hope to be a scientist in the future than girls did. The students in lower grades showed higher scores than those in higher grades. Third, most of children thought themselves doing activity-oriented science in school. Outside school, however, they did not use the knowledge and skills they had learned for science in school. Students in the primary school showed more concept-oriented perception for science than those in kindergarten did. This perception was gradually increased as the grades of the students go up.

The purpose of this study is to analyze 3rd, 4th and 5th graders' probability understanding and raise issues concerning instructional methods and search for the possibility of learning probability. For the purpose, a descriptive study through pencil-and-paper test regarding fairness, sample space, probability of event, probability comparison, independence and conditional probability was conducted. The following conclusions were drawn from the results obtained in this study. First, the 3rd, 4th, and 5th grade students scored the highest in the sample space questions. In descending order of skill, the students scored the highest in sample space following probability of events, fairness and probability comparison. Second, however, the level of independence understanding was low. There was no meaningful differences between grades and the conditional probability was the least understood. The independence is difficult to develop naturally according to cognitive development. The conditional probability recognizing the probability of an event changes in non-replacement situations was very difficult for these students. Third, there were significant differences between the 5th graders and the 3rd and 4th graders in the probability comparison questions. It shows that 5th graders understand the concept of proportion when they compare equal ratio probability of an event. The 3rd graers could do different ratio probability of an event more easily than equal ratio probability of an event after they were instructed on probability comparison.

The purpose of this study was to find out how to operate Technology Home Economics in the 2009 revised national curriculum and Home Economics teachers perception on the current states in the middle schools, focused on intensive course-taking, block-time, and total hours to take the course. Data were collected from the 118 Home Economics teachers nationwide through e-mail from May 25 to June 4, 2011, and analyzed with frequencies, percentage, means, t-test, cross-tabulations, and ANOVA. The results showed that Technology Home Economics was intensively taken in the most of all schools(91.5%) during 4 semesters by senior and freshmen or junior. Teachers were relatively less involved in the decision making process for intensive course-taking than did the school managers and dissatisfied with the fact of intensive course-taking. But a few school adopted block-time and most teachers did not think it was necessary. Over half of schools offered the same 16 hours of Technology Home Economics as in the previous 2007 revised curriculum, but nearly 2 out of 5 schools reduced the hours from 1 to 8 with an average of 2.8 hours. To keep the necessary hours to teach the full contents of Technology Home Economics should be protected. The follow-up research needs to be conducted to investigate the changes in the perception of Home Economics teachers.
