제7차 교육과정 개편에 따라 고등학교 수학교과 구성에 있어, 확률 통계관련 내용이 과거에 비하여 양적으로 많이 증대되었다. 따라서 내용적인 측면에서도 확률 통계관련 각 영역이 단원 목표를 제대로 달성될 수 있도록 구성된다면, 정보화 사회에 요구되는 보다 효율적인 통계교육이 이루어질 수 있을 것이다. 이에 본 논문에서는 고등학교 수학교과 중 확률 통계관련 내용이 단원의 학습목표를 달성할 수 있도록 구성되어 있는지를, 제7차 고등학교 수학 교육과정 해설서에 제시된 중심용어와 기호를 중심으로 '연결망분석(network analysis)'을 활용하여 알아보았다. 그 결과 확률변수를 매개로 확률분포에 대한 개념과 통계적 추정에 대한 개념을 연결하는 서술구조는 통계적인 측면에서 매우 잘 표현되어 있으나, '전수조사'와 '표본조사'는 여타의 항목과 연결되지 않는 등, 일부에 있어서는 기술상에 문제점을 내포하고 있는 것으로 나타났다.

We used SAS program in statistics class as a plan to increase effect of class. Because lease cost of SAS program is high and low-level students felt difficulty of the syntax of SAS program, I planned to introduce other instruction-software. We observe whether it's O.K. to use Excel instead of SAS program and Excel is helpful in having positive attitudes. We try to compare and analyze the merits of two programs. The purpose of this study is to apply Excel to statistics class, cut down the cost of instruction-software, and make students understand statistics more conveniently and easily.

The purpose of this study was to examine the effect of the manipulative materials in the Australian Maths 300 program by applying it to Korean Elementary Mathematics Education - based on parts of 'Probability and Statistics', and 'Symbol and Expression'. In order to this purpose, we select appropriate Maths 300's manipulate materials that could be used to obtain learning objectives within class time for each part, four lessons with the materials were taught at to third, fourth, and fifth grade students of elementary School. The effect of the teaching was analyzed by videotape and student opinion. The results of this study are the following: First, the manipulative tools were almost entirely lacking for the 'Probability and Statistics' section without a 'number of cases' unit. The tools presented in the 'Symbol and Expression' section were helpful in the games that were used for checking preceding learning. Second, the results of using the Math 300 manipulative materials in class showed that the students were eager to be involved in the activities using those materials and to find their own solutions in problem-solving questions that were suited to them; these led to them making their own questions. In response to questioning about the use of the manipulative materials, the students stated that it was easy and fun for them to use the manipulative materials, to solve the problems for themselves, and that they would like to continue practicing the activities in the future. Finally, Studies on the presentation of a variety of manipulative materials including those in this study that can used in problem-solving learning and other learning fields, and the methodology for the use of manipulative materials can be enhanced through further studies.

Purpose: The purpose of this study is to evaluate effects of a health education program based on social cognitive theory on university students with risk factors for metabolic syndrome. Methods: A nonequivalent control group pretest-posttest design was used. Participants were 88 students who had at least 2 risk factors for Metabolic Syndrome (47 students for the experimental and 41 for the control group). The health education program consisted of thirteen sessions. Knowledge regarding smoking and alcohol drinking, self-efficacy and self-esteem were evaluated. t-test, $x^2$-test, Fisher's exact test, and paired t-test were conducted to analyze the data. SPSS/WIN 19.0 Statistics program was used. Results: There was a statistically significant increase in self-efficacy in the experimental group compared to the control group. No significant changes in knowledge and self-esteem were found. Conclusion: The results suggest that the health education program for university students was partially effective. Further work is required to develop more effective health education programs.

The purpose of this study was to analyze the research trends of elementary mathematics education with regard to the topics, methods, subjects, and mathematical contents of such research. For this purpose, the papers published in domestic journals during the recent 5 years (2004-2009) were analyzed. A total of 383 papers from 8 professional journals were analyzed with the 4 criteria. First, the frequent research topics included instructional design and methods, learners' perspectives and abilities, and analysis of curriculum and textbooks in order. Second, qualitative research methodology was used twice as many as quantitative one. Whereas a survey was the most frequent quantitative research method, content analysis and case study were for qualitative methods. Third, research subjects included mainly typical students, specifically fifth and sixth graders. Papers dealing with lower graders or low-achievers as well as pre-service teachers were rare. Lastly, whereas the research on geometry as well as number and operations was active, that of measurement as well as probability and statistics was not. On the basis of these results, this paper includes several implications for the future research direction in elementary mathematics education.

Purpose: The purpose of this study was to examine the effect of nursing record education on the knowledge and performance of nursing record of nurses at small- and medium-sized hospitals. Methods: The participants were 62 nurses working in two small- and medium-sized hospitals. Thirty-two nurses comprised the experimental group, and 30 nurses comprised the control group. Nursing record education was provided for the experimental group. Data were analyzed by x²-test and t-test analysis using the IBM SPSS statistics 25.0 Program. Results: After education, the knowledge (t=2.43, p=.019), performance (t=2.19, p=.033) and behavior scores (t=2.42, p=.018) on nursing record were significantly higher in the experimental group than in the control group. Based on this result, nursing record education is an effective intervention to improve nurses' knowledge and performance in writing nursing records in small- and medium-sized hospitals. Conclusion: We suggest the development of a systematic and standardized education program on nursing record including its legal aspects, for nurses in small- and medium-sized hospitals. The results of this study can be used as basic data for developing a nursing record education program for small- and medium-sized hospitals.

The purpose of this study is to present the relationship between the computer learning and the paper and pencil learning through the math learning (simple computation and complex computation) and the cartoon learning and text learning. The canonical correlation and pairwise t-test of the SMR asymmetry brainwaves of the left and the right brain show the brainwaves with the respect to the manner in which they process information during the specified task by identifying the relative activity of the brainwaves of the left and the right brain. SMR brainwave which known as the scientific measure tool for the activity and the function of the neuronal cell were found to predict the level of the awakening to check the readiness of study preparation. Computer education as a medium of the individualized and the repetitive education shows the difference from the paper and the pencil test in the respect of the differences and the relationship of the SMR brainwave of the learning process.

The purpose of the study is to develop effective teaching methods to strengthen the major learning capabilities of electronic engineering learners through inquiry learning using computing thinking ability. To this end, first, in the electronic engineering curriculum, we performed teaching-learning through an inquiry and learning model related to mathematics, probability, and statistics under the theme of various majors in electronic engineering, focusing on understanding computing thinking skills. Second, an efficient electronic engineering subject inquiry class operation using computing thinking ability was conducted, and electronic engineering-linked education contents based on the components of computer thinking were presented. Third, by conducting a case study on inquiry-style teaching using computing thinking skills in the electronic engineering curriculum, we identified the validity of the teaching method to strengthen major competency. In order to prepare for the 4th Industrial Revolution, by implementing mathematics, probability, statistics-related linkage, and convergence education to foster convergent talent, we tried to present effective electronic engineering major competency enhancement measures and cope with innovative technological changes.
