  • This paper examined vocabulary used in elementary mathematics textbooks and workbooks for the grade band of 5~6. This study focused on the adequacy of vocabulary using 9-degree of semantic difficulty. The results of this study showed that most vocabulary in the textbooks and workbooks was adequate for the target grades. In some cases, however, vocabulary that was supposed to be difficult for the fifth and sixth graders was employed in a way that the meaning of such vocabulary was difficult for students to infer in the given context. The most frequent vocabularies in the main activities of the mathematics textbooks included 'method', 'investigate', 'number', 'communicate', and 'represent'. Based on these results, this study provides 5~6 grade textbook writers with implications on what to further consider in dealing with vocabulary in instructional materials.

  • This study is aimed at developing the STEAM instruction materials for mathematics subject-based advanced technology and ICT teaching tools. In order to develop the STEAM materials, a PDI model in which the implementation and evaluation steps were simplified to Improvement was used. The developed STEAM materials were revised and supplemented by a group of experts. The subject of the STEAM class material developed in this study is 『Graph! The bridge that connects the past, present and future』 , 『You are the same but different!』 , 『Creating a virtual reality three-dimensional space together』 , 『And making interesting figures』 and 『Cover the roof of the turtle ship!』 . As a suggestion based on the results of this development study, various STEAM education materials should be developed and shared so that STEAM education can be performed in the elementary education field. And for the spread and settlement of STEAM education, the cultivation and expansion of STEAM education capabilities of on-site elementary school teachers or pre-service teachers will be an absolute prerequisite. And this suggests the need for a continuous and long-term approach to follow-up research on STEAM education.

  • In this research, in order to obtain teaching/learning implications for effective use of questions when teaching number and operation area, the types of questions presented in chapters of number and operation area of 2015 revised elementary math textbooks and the function of questions were compared and analyzed by grade cluster. As a result of this research, the types of questions presented in chapters of number and operation area showed a high percentage of occurrences in the order of reasoning questions, factual questions, and open questions not calling for reasoning in common by grade cluster. And reasoning questions were predominant in all grade clusters. In addition, in all grade clasters, the proportion of questions acting as a function to help guess, invention, and solving problems and questions acting as a function to help mathematical reasoning were relatively high. As such, it can be inferred that the types and functions of the questions presented in chapters of number and operation area are related to the characteristics of the learning content by grade cluster. This research will be able to contribute to the preparation of advanced teaching/learning plans by providing reference materials in the questions when teaching number and operation area.

  • The study was intended to investigate elementary schoolers' oral health status according to whether the school have and manage an school oral health clinic or not in order to provide useful information for continuously developing the school oral health clinic 1,163 children in Hwasan elementary school in Hwasung city and 485 children in S elementary school in the same locality were selected as the experimental group and the control group, respectively, and orally examined from May 1st to 30th, 2004. The findings from the oral examination were as follows. 1. DMF rate was higher in the higher grades in both the groups. The rate was lower in the experimental group with 45.1% of the children than in the control group with 65.3% of the children. 2. DMFT rate also were higher as the grades were higher in both the groups. The ratio was lower in the experimental group with 30.4% of the children than in the control group with 44.6% of the children. 3. DMFT index was 1.0 in number in the experimental group and 1.6 in the control group. Index increase from the 1st grade to the sixth grade was also more positive in the experimental group. 4. DT rate was a little higher in the experimental group in the first graders, but comparatively decreased to the grades while increased in the control group. In the sixth graders, the rate was 42.4% in the experimental group and 87.7% in the control group, the former was less than the latter by about 50% point. 5. FT rate was a little higher in the control group for the first graders but increased in the experimental group to the grades. The rate in the sixth graders was higher by more than double in the experimental group. Based on the above findings, the region of the study had better oral health statistics than in other regions. The operation of school oral health clinics that provide dental health care to children at the right time seems to contribute to enhancing their dental health status by preventing against dental diseases and changing their relevant knowledge, attitude and behaviors. In the future, more school oral health clinics should gradually be prepared to push ahead with a sustained, extensive dental health project geared toward school-aged children. To make it happen, dental hygienists who are professional medical personnels should be taken advantage of, and in order to beef up the efficiency of preventive measures and oral health education, the best dental health care services should be offered by harnessing dental hygienists and dentists who work at public dental clinics run by local governments.

  • This study was carried out an elementary school located in B-myeon and K-myeon of Gimje. One school (test group) with a school oral health care office and three schools (control group) without school oral health care offices were selected as sample schools. The dental caries prevention effects were compared between third to sixth graders who received benefits of the school continued oral health management program of K health office in Gimje, and first and second graders who did not receive the benefits due to the suspension of the program. The decayed, missing, and filled (DMF) rate, that received the benefits of the program, the test group was 58.9% and the control group was 76.1%, showing significant difference (p<0.05). For the DMF teeth (DMFT) rate, the who received benefits from the program, the test group was 41.1% and the control group was 64.2%, showing significant difference (p<0.01). For the DMFT index, the third to sixth graders that received benefits of the program, the test group was 1.73 and the control group was 3.66 showing significant difference (p<0.001). For the decayed teeth (DT) index, it was 0.72 for the test group and 1.96 for the control group showing significant difference (p<0.001). For the filled teeth index, the test group was 0.63 for the test group and 0.99 for the control group showing significant difference (p<0.05). For the DT rate, the total test group was 57.23% and 64.16% for the control group. For who received benefits from the program, the DT rate was 54.81% for the test group and 60.98% for the control group. The effects of the student continued oral health management program carried out by the oral health office can be confirmed. It is judged that efforts for continuous maintenance and promotion will be necessary to improve the oral health of students.
