  • 고대의 인도수학은 산스크리트어로 쓰여 있고, 수학의 법칙이나 문제들은 구전되었거나 필사본의 형태로 경전 속에 포함되어 있으며, 학생들이 암기를 쉽게 할 수 있도록 아주 간결하게 정리되어 있다. 고대 인도의 많은 수학자들은 일찍이 십진법, 계산법, 방정식, 대수학, 기하학, 삼각법 등의 연구에 공헌하였다. 이 논문은 고대 인도수학과 다른 문명권의 수학발전을 비교하였다. 고대 그리스 수학이 공리적이고 연역적이라면, 인도수학은 양적이며 계산적이지만 원리를 가지고 문제를 해결하는 특성이 있다. 고대 인도와 타 문명권의 수학을 비교하는 것은 오늘날 수학교육과 수학사 연구에 의미가 있는 것으로 사료된다.

  • The purpose of this study was to find out and analyze the science teacher's teaching methods. A total of 35 teaching methods were abstracted from the previous studies and the relating literatures. An instrument to measure the frequencies of using methods was developed and then tested to middle school science teachers. The Results of two factor analysis methods were compared. The results are as follows: The instruments's reliablity coefficient(Cronbach ${\alpha}$) was 0.7707. The teaching methods which middle school science teachers have used frequently were represented as the proposing of the learning objectives, the deductive teaching, the experimental activities by teacher's guide, the summarization after explanation, the reading text etc. Also, it was revealed that they have not use the diagnostic evaluation, the formative evaluation, the experimental activities by student's design, the instructional medium. By confirmatory factor analysis, the 1st factor included 13 teaching methods and 2nd and 3rd factor included 9 and 7 methods respectedly. The meaning of 1st factor was interpreted to stimulate student's learning motives. And the other's were about the development of instruction. In exploratory factor analysis factors were overlapped or more fined. These were due to the structure of factors.

  • Scientific reasoning is one of the main concerns in current science education. This study have tried to answer on the question whether Korean science education has the potential to help improve of students' ability to think scientifically. Therefore, the present study investigated the relationship between reasoning patterns evident in science textbook and science examination items, and students' scientific reasoning skills across grades in Korea. 1975 subjects (1022 females and 953 males) were administered in the Lawson's Test of Scientific Reasoning skills. Forty seven science textbooks and 240 assessment instrument were analyzed by several scientific reasoning keys. Scientific reasoning patterns were adopted from Lawson's classification which characterized the patterns as the empirical-inductive and the hypothetical-deductive. This study found that reasoning patterns evident in textbook analyses and assessment instrumental items do not evidentce the potential to stimulate the development of students' reasoning skill. In order to improve the students' abilities to think and achieve, higher levels of reasoning must be included in the science textbook and examination. Further, some of scientific reasoning processes, such as generating hypotheses, designing experiments, and logical prediction, were not found in science textbooks and test items in Korean secondary schools. This study also discussed the educational implication of these results and further studies about to develop student's reasoning ability.

  • Purpose : To explore the person-centered care (PCC) experienced by critical patients. Method : This qualitative study deductively examined the attributes of the PCC model proposed by Jakimowicz and Perry. The participants were 16 patients who were recently discharged from intensive care units at a university hospital. Data were collected through in-depth interviews and were analyzed using the deductive method of content analysis. Results : A total of 4 categories, 16 subcategories, and 33 codes were generated from 171 meaningful statements. The final 4 categories were "compassionate presence," "professional interaction," "outstanding competency," and "patient identity." These were consistent with the main attributes of Jakimowicz and Perry's model. However, most of the codes belonged to the "compassionate presence" and "patient identity" categories. Among the attributes of the model, "continuity of nursing," "therapeutic relationship," "expert knowledge," "clinical knowledge," "evidence-based intervention," and "patient's rights" were not derived as codes. Conclusion : These findings deepen the understanding of the PCC model from the patient's point of view. The main attributes of PCC identified in the current study can be applied to the development of practical guidelines for intensive care nursing. In addition, we recommend the development of a PCC measurement tool for critical care patients.

  • The GyoJungEuiSeoGook(校定醫書局, the bureau for revising of medical books) which was established in the 2nd year of InJong GaWoou of Song dynasty, made comparative analyzation about various kinds of publication and reference materials of all classical medical books that was published until Jin Han and Su Dang dynasty, revised the medical books like as Bozushinnongboncho(補注神農本草), Zungkwangbozuhwangjenegyungsomun(重廣補注黃帝內經素問), Shanghanlon(傷寒論), Bigupchunggumyobang (備急千金要方), Magkyung(脈經), Oedaebiyo(外臺備要), Hwangjechimgugapeulgyung(黃帝鍼灸甲乙經), Cchunggumikbang(千金翼方) etc. The signification of such revision was not only to preserve the materials which may be lost before, bibliographically and also make the books of Hwangjenegyung(黃帝內經), Shanghanlon(傷寒論) etc. become more regularly. And it made the foundation of Korean Medical research depends on the documentary records so as to make it have big development by deductive method till the beginning of modern age. The success of GyoJungEuiSeoGook(校定醫書局) indicates that the stagnation of Korean Medical research due to it's behind with the development of politics-economy, social culture and scientific technology which based on western scientific culture. So we may draw the conclusion that the success of scientific research needs to parallel with the external and internal factors of the surrounding science.

  • The purpose of this study was to develop math creative problem solving test in order to identify the mathematically gifted on the basis of their math creative problem solving ability and evaluate the goodness of the test in terms of its reliability and validity of measuring creativity in math problem solving on the basis of fluency in producing valid solutions. Ten open math problems were developed requiring math thinking abilities such as intuitive insight, organization of information, inductive and deductive reasoning, generalization and application, and reflective thinking. The 10 open math test items were administered to 2,029 Grade 5 students who were recommended by their teachers as candidates for gifted education programs. Fluency, the number of valid solutions, in each problem was scored by math teachers. Their responses were analyzed by BIGSTEPTS based on Rasch's 1-parameter item-response model. The item analyses revealed that the problems were good in reliability, validity, difficulty, and discrimination power even when creativity was scored with the single criteria of fluency. This also confirmed that the open problems which are less-defined, less-structured and non-entrenched were good in measuring math creativity of the candidates for math gifted education programs. In addition, it discriminated applicants for two different gifted educational institutions and between male and female students as well.

  • This year I published a Korean translation of On War in three volumes, written by Prussian general Carl von Clausewitz. I believe it is the first unabridged Korean translation from the original German text, Vom Kriege. It is true that the work has been translated into Korean several times, but some translations have been done from English or Japanese versions, while others are abridged ones. It is not easy to make a good translation of On War, partly because the book is actually an unfinished work, and partly because it contains almost all academic subjects in social sciences. Moreover, two aspects of the dialectical logic in the book make it more difficult to understand. One is inductive reasoning, the other is deductive explanation. The former is to 'ascend' to draw principles and generalizations from empirical experience, the latter is to 'descend' to describe and explain given principles, often by concrete examples. Considering these difficulties, if we want to have better translations than existing ones, there should be substantial commentaries which contain not only history of wars, but also biographies and geographies concerned. I hope that On War can be taught and studied in many universities, for it will make it easier to produce reliable commentaries.

  • Euclid's Elements has been considered as the stereotype of logical and deductive approach to mathematics in the history of mathematics. Nonetheless, it has been criticized by its dryness and difficulties for learning. It is worthwhile to noticing mathematicians' struggle for providing some alternatives to Euclid's Elements. One of these alternatives was written by a French scientist, Pardies who called it 'Elemens de Geometrie ou par une methode courte & aisee l'on peut apprendre ce qu'il faut scavoir d'Euclide, d'Archimede, d'Apllonius & les plus belles inventions des anciens & des nouveaux Geometres.' A precedent research presented its historical meaning in traditional mathematics of China and Joseon as well as its didactical meaning in mathematics education with the overview of this book. However, it has a limitation that there isn't elaborate comparison between Euclid's and Pardies'in the aspects of contents as well as the approaching method. This evokes the curiosity enough to encourage this research. So, this research aims to compare Pardies' Elements and Euclid's Elements. Which propositions Pardies selected from Euclid's Elements? How were they restructured in Pardies' Elements? Responding these questions, the researcher confirmed his easy method of learning geometry intended by Pardies.

  • Under 2009 Revised Mathematics Curriculum and 2015 Revised Mathematics Curriculum, mathematics teachers can help students inductively express real life problems related to sequences but have difficulties in dealing with problems asking the general terms of the sequences defined inductively due to 'Guidelines for Teaching and Learning'. Because most of textbooks mainly deal with the simple calculation for the sums of sequences, students tend to follow them rather than developing their inductive and deductive reasoning through finding patterns in the sequences. In this study, we reconstruct 8 problems to find the sums of sequences in MukSaJipSanBup which is known as one of the oldest mathematics book of Chosun Dynasty, using the terminology and symbols of the current curriculum. Such kind of problems can be given in textbooks and used for teaching and learning. Using problems in mathematical books of Chosun Dynasty with suitable modifications for teaching and learning is a good method which not only help students feel the usefulness of mathematics but also learn the cultural value of our traditional mathematics and have the pride for it.
