  • 본 연구에서는 통계적 변이성 사고 요소를 변이성 인식, 변이성 설명, 변이성 제어, 변이성 모델링, 표본의 이해, 표집분포의 이해로 구분하고, 이들 요소 사이의 관계를 조사한다. 연구결과 통계적 변이성 사고 요소를 변이성 인식, 변이성 설명, 변이성 제어, 변이성 모델링, 표본의 이해, 표집분포의 이해로 구분하는 것이 타당함을 확인하였다. 상관관계 분석결과 변이성 인식, 변이성 설명, 변이성 제어에 대한 변이성 모델링, 표본의 이해, 표집분포의 이해의 상관계수가 유사한 것으로 나타났는데, 이러한 사실을 바탕으로 표집의 이해를 변이성 모델링, 표본의 이해, 표집분포의 이해를 포괄하는 잠재변수로 설정할 수 있었다. 또한 변이성 인식과 변이성 제어는 표집의 이해에 영향을 미치는 것으로 나타난 반면, 변이성 설명은 표집의 이해에 영향을 미치지 않는 것으로 나타났다.

  • 본 연구에서는 변이성 인식 능력을 중심으로 수학영재학생들과 일반학생들의 통계적 사고 수준을 비교한다. 연구결과 측정상황에서 중학교 수학영재학생들과 일반학생들 사이에 통계적으로 유의한 차이가 있는 것으로 나타난 반면, 초등학교 수학영재학생들과 일반학생들 사이에는 유의한 차이가 나타나지 않았다. 그리고 우연상황에서도 중학교 수학영재학생들과 일반학생들 사이에 통계적으로 유의한 차이가 있는 것으로 나타난 반면, 초등학교 수학영재학생들과 일반학생들 사이에는 유의한 차이가 나타나지 않았다. 그러나 수준별 빈도를 조사한 결과 수학영재학생들의 사고 수준이 상위 수준에 집약되어 분포하기보다는 일반학생들의 사고 수준이 상당부분 중첩되어 있는 것으로 나타났다. 이러한 연구결과는 수학영재학생들에게 통계를 지도하는 데 있어 유용한 시사점을 제공한다.

  • This study aims to reflect experts' opinions in analyzing a design thinking as foundation of multidisciplinary education. For this purpose, a delphi survey was conducted with 20 experts in three sessions from May 1 to June 25, 2012. To analyze the collected data, descriptive statistics, including frequency, percentage, the mean, and standard deviation were implemented, and internal reliability test on the survey instrument was carried out for statistical processing. The main results are as follows : First, the delphi analysis on intuitive thinking of design thinking suggested 7 items(to pursue the possibility of outside, to pursue the possibility of applying new forms of technology, content planning, facing a complex real-world phenomena etc.). Second, the delphi analysis on logical thinking of design thinking suggested 7 items(executed repeatedly, reasoning and verification, artificial intelligence, a decision support system etc.) Third, the delphi analysis on subjective thinking of design thinking suggested 9 items(user experience measuring, user satisfaction ratings, user requirements analysis, user interface design, behavioral responses of the human etc.). Fourth, the delphi analysis on objective information of design thinking suggested 8 items(information management system, simulation, production process, information exchange and sharing etc.). According to the results of the delphi analysis, design thinking can be seen as the foundation of multidisciplinary education. Suggestions were made for discussion about the main results and further researches.

  • This study was a cross-sectional descriptive survey study that confirms the effect on subjects that prefer clinical practice in order to prepare basic data for efficient clinical practice guidance for nursing college students. The study participants were 201 students attending C University, and the data collection period was from October 1 to October 15, 2022. The collected data were analyzed using SPSS 18.0 as descriptive statistics, Pearson correlation, Chi square test, ANOVA test, and Multiple regression test. As a result of the analysis, it was found that clinical decision-making and critical thinking were correlated under the statistical significance level (r=.730, p<0.01). The most favorite clinical practice department was community nursing, and male students preferred community nursing the most (Male=45.6%, χ2=.000), female students were found to prefer similar levels of practical subjects with child nursing , adult nursing, and maternal nursing(χ2=000).Clinical decision-making was found to be higher in students who preferred community nursing at a statistical significance level than those who preferred child nursing (F=4.91, p<0.01). Critical thinking was higher among students who preferred adult nursing than those who preferred other subjects (F=4.65, p<0.01). Through the analysis results, it was found that general characteristics vary, but clinical decision-making ability and critical thinking affect the preference of clinical practice subjects. Therefore, based on the results of this study, the professor of clinical practice suggests the development of a program to foster clinical decision-making and critical thinking to make students interested in clinical practice subjects.

  • 유사성을 근거로 하는 개연적 추론인 유추는 수학뿐만 아니라 물리 등의 여러 분야에서 개념 형성, 문제해결, 새로운 발견 등을 위해 사용되는 하나의 사고전략이다. 통계교육자들은 통계에서도 역시 유추가 유용한 사고전략으로 사용될 수 있다고 언급한다. 본 연구에서는 수학과는 다른 특성을 지닌 통계에서 학생들의 유추적 사고의 특징을 살펴본다. 이를 위해 수학영재학급 학생들을 대상으로 실생활 맥락이 담긴 통계문제를 기저문제로 제시하고 이와 유사한 문제를 만들도록 하였다. 학생들이 만든 문제는 기저문제의 통계적 맥락의 보존 여부 및 기저문제의 기본구조 유지 여부에 따라 다섯 가지 유형으로 분류되었다. 각 유형의 특징을 분석한 결과 다음과 같은 시사점을 얻을 수 있었다. 통계에서는 기본구조가 유지되어도 통계적 맥락이 훼손되는 경우 그 문제의 의미를 찾을 수 없으나, 기본구조가 변형되었다 하더라도 통계적 맥락이 보존되는 경우 통계적 개념에 대한 재개념화에 기여할 수 있다는 가능성을 확인하였다.

  • 통계는 삶의 문제에서 출발하여 주어진 문제를 해결하기 위해 통계문제로 번안되고, 자료가 정의되고 수집되어 적절하게 통계를 활용하여 원문제의 해결을 해야 한다. 그러므로 통계교육은 이러한 연장선상에서 유기적이고 체계적으로 이루어져야 한다. 이 논문에서는 초등 통계 영역이 가지는 문제점들로 교육과정상의 문제점, 교과서 구성 측면에서의 문제점, 수업 운영의 문제점, 실생활과의 연계 부족, 다른 영역과의 연계성의 문제, 통계에 대한 인식의 문제 등을 살펴보았다. 이러한 문제점의 해결방안에 대해 탐구하여 초등통계교육의 개선을 위한 시사점을 제공하는데 그 목적이 있다.

  • The purpose of this study was to investigate effects of critical thinking dispositions on vocational personalities in university students. Subjects were 111 University students in Busan. The questionnaire used in this research were Holland's Vocational Personality Questionnaire and California Critical Thinking Disposition Inventory. The results were analyzed by correlation analysis and enter multiple regression using the SPSS statistical package (SPSS for windows 12.0; SPSS Inc., Chicago, IL, USA). The study results were as follow: First, the students had much more S and R vocational personality characteristics than the others in vocational personality characteristics and had higher inquisitiveness and self-confidence scores than the others in critical thinking dispositions. Second, there were significant relationships between vocational personality types and critical thinking dispositions. Third, some of the vocational personality types were affected by the critical thinking dispositions. Especially I, E, and C personality of vocational personalities were prospected by critical thinking dispositions. Therefore, It's necessary that we understand the relationships between vocational personality types and critical thinking dispositions. Also we have to think over how to development career programs for university students to match to the learner's vocational personality type and critical thinking dispositions.

  • Purpose: Higher Order Thinking Skills is one of the important aspects in education that must be mastered by the students in order to be qualified in competing at international level. Success in mastering HOTS among the students is always linked to preparation of a good and conducive learning environment. However, does this connection impacts the students' HOTS achievement? Therefore, this research is carried out in order to evaluate the relationship between HOTS and learning environment with the main focus on Accounting Principle Elective Subject (MPEI PP). Research design, data and methodology: Research in the form of correlation is implied in this study and it involves 59 Form 5 students that has learned all syllabus in Form 4's MPEI PP. Results: Evaluation of HOTS level is based on Taxonomy Bloom that covers applying skill, analysing skill, evaluating skill, and creating skill. Result from data analysis found that there is a very weak correlation (r = 0.02) between the two variables with regression equation of average grade point = 75.023 + (-.273) Learning Environment. Conclusion: Thus, a non-significant relationship between HOTS and learning environment is successfully proven through correlation and regression statistical analysis.

  • Our society has changed from an industrial society to a knowledge - based society, and the need for new knowledge creation activities through the convergence of various knowledge is emphasized. In accordance with these changes, universities aiming at nurturing human resources for society have sought new approaches and changes. The discussion of various curriculum for the future talent training in the university is aimed at the goal of developing problem solving ability irrespective of the subject of education or major. In this study, we tried to show that computational thinking ability can be improved by strengthening creative team activities by combining design thinking method in computer curriculum of general education course of university. To do this, we conducted a design thinking team project for students of computer general education course at G university in Gyeongnam province and conducted a survey. The results of the questionnaire were verified by statistical methods. The variables of this study satisfied both the validity and the reliability. Multiple regression analysis showed that knowledge sharing, team activity satisfaction, and design thinking project satisfaction factors all affect computing thinking ability.
