It is critical to examine changes in teachers' beliefs on how to teach and learn mathematics through teacher education programs. This study aims to develop an instrument measuring elementary pre-service teachers' beliefs on student- and teacher-centered instruction. After developing questionnaires with mathematics education experts, the structural validity of the instrument was evaluated by collecting and analyzing data from 166 pre-service teachers. Parallel analysis and exploratory factor analysis were applied sequentially to collect validity and reliability evidence. The results showed that this instrument can be used to examine changes in pre-service teachers' two different types of belief: student- and teacher-centered instruction. We also suggested how to interpret scores appropriately.

Sampling designs often use stratified sampling, where elements or clusters of the study population are divided into strata and an independent sample is chosen from each stratum. The stratification strategy consists of stratification and sample allocation, which are important issues that are repeatedly considered in survey sampling. Although a stratified multistage sample design is often used in practice, the literature tends to discuss simple sampling in terms of stratum effects or stratum efficiency. This study examines an existing stratum efficiency measure for two-stage sampling and further proposes additional stratum efficiency measures using the design effect model. The proposed measures are used to evaluate the stratification strategy of the sample design for high school students of the 4^th Korean National Environmental Health Survey (KoNEHS).

The purpose of this study is to seek a measure to institutionalize the curriculum of Korean homeschooling by comparing and analyzing curriculums of homeschooling between the United States and South Korea. To do so, literature review was conducted to derive analysis criterion and curriculums of homeschooling between the United States and South Korea were compared and analyzed. The major findings of analyses are as follows. First, from the perspective of educational goal, homeschooling families of both countries are similar in which they preferentially seek private goal but also consider social goal as well. Second, in the perspective of educational content, a diversity in course of study, textbook and other education materials of homeschooling in the United States is substantially attained when Korean homeschooling families suffer shortage. Third, in terms of educational implementation, homeschooling of both countries attained an autonomy in instructional time and a diversity in instructional space and method, however, unlike homeschooling in the United States, homeschooling in South Korea is experiencing difficulties due to lack of homschooling organization, homeschooling co-ops and web-site space. Fourth, in the perspective of educational evaluation, homeschooling in South Korea, unlike its comparison target, has not been certified as a formal education as well as not been accepted from universities. Based on these analysis results, conclusion and discussion have been proposed.

Participants requested the followings contents of an in-service educational program regarding the practical problem focused home economics curriculum. First, most of participants strongly desired to participate in an in-service educational program when a program provided. The participants wanted to be a professional, who is able to explain logically with philosophical background and knowledge about the practical problem focused home economics curriculum. Second, participants requested the followings regarding practical problem focused home economics curriculum for the contents of an in-service educational program: philosophy of home economics, setting a perspective on each content areas, development of practical problem, watching a sample class unit, developing teaching materials and motivation stimulating questions, designing of instruction and lesson plans, class presentation and peer evaluation, constructing paper and pencil test items, and feedback from expects on the practical problem focused home economics curriculum. Third, participants wanted an in-service educational program to be a combination of theory and practice, and at least 50% of it allotted to practice. Participants thought that both peer participants and experts from university would evaluate them whether they achieved the objectives of the in-service educational program if an in-service program has to evaluate participants. Participants would evaluate an in-service educational program excellent when they become empowered to teach other home economics teachers the theoretical aspects of the practical problem focused home economics curriculum and the practical aspects as well. Based on the results of this study a framework of the 30 hours practical problem focused home economics curriculum was proposed.

Recently, STEM education and improvement in creativity took a lot of attention in local and foreign educational programs, and the robot education is regarded as one of the answers which can achieve the objectives. The robot education is quite active locally in various ways including robot classes for after school program in elementary schools, a number of robot competitions, and education for the gifted. Under these circumstances, the qualification test for robot technology is developed to provide a standard for evaluating professional knowledge on robotics and is currently under consideration to be one of the government-approved qualification tests. However, compared to the robot classes for after school program, this test is not well recognized by most teachers in elementary and middle schools. This paper addresses and analyzes the current status of the test, in particular, backgrounds, qualification standards, organizing committee, intention of presenting questions, examples of problems used in the test, and demands raised by applicants, etc. Base on the analysis, some suggestions are made to establish a solid standard for evaluating robot technologies. It is suggested that the level of difficulty and contents covered should be properly adjusted considering the level of applicants. In addition, it is essential to provide well organized supplementary material for students and wide range of contents on robot technology. Finally, some efforts including cooperating with the robot classes for after school program should be made to invigorate the test.

The purpose of this study was to investigate the educational status of dental hygiene process of care and to provide foundation for introducing curriculums focused on it. Questionnaire (14 questions) on educational status of clinical dental hygiene based on dental hygiene process of care was distributed in 50 dental hygiene schools with full classes. Research was performed with structured questionnaires on the basis of previous literatures, and interview and email survey was conducted. Collected data were analyzed with Frequency analysis, Descriptive statistics, and Chi-square test using SPSS 12.0, and the results were as follows. The average student to clinical dental hygiene faculty ratio of 22 to one regardless of year of curriculum. Sixty two point five percent of dental hygiene school reported having a curriculum about comprehensive dental hygiene process. Regarding the distribution of lecture and practical curriculums, they were less focused on dental hygiene diagnosis (68.8%), planning (65.6%) and evaluation (68.8%) than on assessment and implementation. Just over half (56.7%) reported having education of dental hygiene process of care during the course of curriculum. In conclusion, it is most desirable to provide integrated education based on dental hygiene process of care by reinforcing dental hygiene diagnosis, planning, and evaluation step.
