The purpose of this study was to investigate the role of calculators as a cognitive tool rather than calculating tool in learning elementary school mathematics. The calculator activities on multiplying two numbers ending with 0s or two decimal fractions and mixed four operations were developed, and exploratory lessons with the activities were implemented to three 3rd graders and two 5th graders. The results were shown that calculators provided an alternative effective learning environment: students were able to use heuristic thinking, reason inductively and successfully investigate principles of mathematics through the pattern recognition. And finally, we discussed the heuristic method through utilizing calculators.

The purpose of this study is to investigate the teaching methods of prediction, inference, and hypothesis. The major data source was gathered by in-depth interview of science teachers (about 50-80 minutes for each interview). The interviews were conducted using semi-structured interview protocol, which consisted of three major parts: (1) Teacher's definition of prediction, inferences, hypothesis, (2) Teaching methods of prediction, inferences, and hypothesis and (3)Reasons of teacher's inaccurate perceptions of prediction, inference, and hypothesis. All the interviews were audio-taped and transcribed. Topics in the questions were categorized. The results were as follows: Teachers recognized the importance of prediction, inferences, and hypothesis. But they didn't have an accurate conception and they have great difficulty in classifying and explaining the prediction, inferences, and hypothesis. To find out the teaching methods, researcher investigated the inquiry activities, teaching times, usage of terms, teachers' questions, and teaching difficulties. Reasons for having difficulty were lack of teaching competency, difficulties from the students, and problems in the present curriculum. Finally, we discovered that the reasons for teacher's inaccurate perceptions of prediction, inference, and hypothesis were two factors. One is internal factors, which include the lack of scientific inquiry process skills, burdens of science subject and lack of science education knowledge. The other is external factors, which include education system for evaluations and lack of teacher education. In conclusion, this study suggested establishing more elementary teacher education programs that include strengthened concepts of inquiry process skills and teaching methods.

2007 Curriculum Revision adopted new Inquiry Activities in mathematical textbooks. So it is critical to analyze the problems of actual application of Inquiry activities in the classrooms. For this purpose, we analyzed the Inquiry activities of Measurement Area of the textbooks and find the appropriate solutions. Secondly, we develop the reorganization materials to fix and solve the existing problems found in the previous problem analysis, and apply the development materials and examine the effects afterwards. The results of the survey indicated that most of teachers are well aware of the importance of Inquiry Activities. However, many teachers answered that Inquiry activities does contain neither diverse strategic approaches nor solutions accommodating with various learning levels of students. The most difficult points to educate Inquiry Activities are that it is difficult to teach students based on individual learning level and that activities consist of mainly short answers that makes it difficult to do in-depth Inquiry Activities. Analyzing Inquiry Activities in the textbook shows that Inquiry Activities in some chapters were constructed as simple sentence questions or presented with the solving process in the questions themselves. The following application classes were implemented by partially taking advantage of the newly developed reorganization materials. Then, the effects were measured by before and after questionnaires, the survey to teachers, and the results of activities. The reorganization materials were effective at arousing the curiosity from students as well as enabling the natural ability-level driven classes.

Purpose : Sexual abuse especially in younger group have been growing. This study was performed to propose the fundamental data for developing early education program to prevent damage from sexual harassment in elementary school students. Method : Questionnaire survey on cognitions and experiences about sexual harassment was done on 3125 elementary school students from seven elementary schools in Busan area from January to March, 2002. Data analysis was done with SPSS (ver 10.0). Results : Though 82% of the students have ever herd about sexual harassment previously, but self assessment of 'well-known' was only 5%. About 40% of them have ever experienced audio-visual sexual materials mainly through PC (18%), media (14%), etc. And, 60% of them have ever educated about sexual harassment. In cognitions, they agreed 'unwanted touch', 'intentional showing his (her) own body', 'send lewd mails and pictures', but disagreed 'ask massage from aged', 'gaudy joke' as one of sexual harassment. In attitudes, 'no response', 'defense with friends and family', 'express unpleasantness apparently' were desirable pattern, instead, 'his (her) own responsibility', 'problem only between person concerned', 'neglect is the best way' were undesirable. About 24% of them have ever experienced at least one of the fifteen types of sexual harassment with major types of lewd mails pictures (11%), hugging (5%), ask massage (4.7%) and unwanted touch (3.3%). The experience by gender was higher in girls (25.0%) than boys (22.4%) with no statistical significance. The mean level of cognition and attitude out of one hundred was $70.3{\pm}28.1$ and $73.5{\pm}15.9$, respectively. The mean frequency of experience was $0.4{\pm}1.1$ times. The level of cognition and attitude was higher in girls, 6th graders, and in ever educated group (p<0.001). Conclusions : The cognition level of elementary school students about sexual harassment assessed considerable. And, they also experienced several types of sexual harassment, though not too much. Therefore, compatible education program let them able to protect themselves from sexual harassment should be developed and applied even in early school age.

In accordance with the 2015 Revised Practical Curriculum, software education for elementary school students will focus on making software and not using software. Therefore, we must revise the computer education curriculum at national universities of education to include classes on programming. In this study, I surveyed computer education students to learn more about their programming experience as well as their understanding of and necessity for software education. Based on results of the survey, I found that students had a strong understanding of software education and that they recognized its importance; however, students who had not experience related to programming education had a weak the understanding and necessity for software developing education. I suggested that software-related courses should open as a major subjects at the universities.
