  • The research is aimed at investigating the development and application of high school biology classes utilizing discourse-typed inquiry learning program fitted with POE, and the corresponding effect on student's academic achievement and attitude toward science. 4 classes of 11th graders in a general high school located in Busan were selected as subjects. Biology I, 'Circulation' unit was lectured for 4 weeks (6 classes), and the experimental group underwent classes utilizing discourse-typed inquiry learning program fitted with POE. The control group was taught identical major learning contents, but based on the learning objectives and research activities provided by Biology I textbook. As a result of application, first, the discourse-typed inquiry learning program fitted with POE exhibited positive consequences of linking previously acquired knowledge and the new learning attained through experiments, as well as not only improving the students' problem solving capacity through diverging questions from the teachers to drive the students' higher-level contemplation, but also enhancing student academic achievement by assisting their logical thinking. Second, POE-fitted discourse-typed inquiry learning program rendered presupposing session of the experiment that resulted in drawing learners' attention in advance, and incited active participation in the learning process through solving the contradiction between what was actually observed and what was expected, which eventually proved to lay out positive impact on students' attitude toward science.

  • The purpose of this study was to investigate the errors in science inquiry research reports written by students who won the encouragement award at the National Science Fair, and analyze the frequency of error types by school levels. The framework for analysis was constructed based on the table of contents of the students' science inquiry research reports, and the reports were analyzed for errors in six stages: Research question/hypothesis, prior research, experimental procedure, results, conclusions, and references. The study identified several types of errors at each stage, such as unreasonable research questions and wrong hypotheses in the research question/hypothesis stage, and limited considerations under certain conditions and selection of inappropriate experimental instruments in the experimental procedure stage. The study found that the frequency ratio of experimental procedure error was the highest across all school levels, and the order of errors varied by school level. Frequency ratio of error types of school level was: in the elementary school students' reports, errors were analyzed in the order of experimental procedure (36.88%), prior research (17.02%), conclusions (16.31%), research question/hypothesis (13.48%); In the middle school students' reports, experimental procedure (42.86%), conclusions (20.00%), prior research (14.28%), results (11.43%), research question/hypothesis (10.01%); In the high school students' reports, experimental procedure (45.16%), research question/ hypothesis (16.13%), conclusions (16.13%), and prior research (11.83%). The findings could be used to guide teachers in helping students conduct scientific inquiry research or write reports.

  • This study was designed to assess the needs for nutrition education and educational materials for older adults. Two cross-sectional surreys were conducted. The first survey, conducted by personal interviews, was part of the large-scale elderly nutrition study. Subjects were adults aged 50 and over, recruited from 6 large cities and 8 middle-sized cities(n = 1,850). The second survey, done by mail survey using open-ended questions, was conducted with dietitians working at public health centers or hospitals(n = 53). Adults aged 50 and over were interested in topics such as healthly eating(32.1%), hypertension/stroke and diet(22.1%), osteoporosis and diet(11.4%), and diabetes and diet(9.2%). Television and radio(58.2%), health professionals(12.2%) and friends(7.9%) were common sources of nutrition information. Preferred topics of nutrition education and sources of nutrition information were different by general characteristics of subjects, suggesting that nutrition education or educational materials be planned considering the characteristics of subjects. About 70% of subjects indicated that they sometimes use or do not use nutrition information in daily lives, suggesting the need to provide more practical information. Among 53 facilities responding to the second survey, 73.6% provided nutrition education for older adults. Common topics for nutrition education included diabetes(39.3%), hypertension and stroke(19.1%) and general nutritional management(11.2%). These were consistent to the topics preferred by older adults. As materials In elderly education, dietitians wanted primarily to use leaflets and slides. Boards, booklets and posters were other commonly cited materials. For contents of elderly educational materials, dietitians mentioned the nutritional management for age-related diseases(33.8%), general nutritional management for older adults(25.4%) and practically applicable information(19.7%). They also suggested that nutrition education materials for the elderly should use larger print and attractive pictures, and be easily understood, as well as presenting simple, specific and practical information. These results provide baseline information for developing nutrition education and educational materials for older adults.

  • Two biology modules were developed previously for the purpose of improving creativity and scientific thinking of secondary school students. A hypothetical-deductive experimental procedure was reflected in the module when students themselves can perform a series of activities of making hypothesis and designing an experiment to solve the questions. They followed a series of scientific processes to determine some characteristics regarding plant pigments and the transport process of materials in living organisms. Four classes of 9th graders in'S' Science High School were divided into the experimental and the control group. The same contents of the modules were taught to the control group by the traditional experimental way. The students' creativity, scientific thinking, scientific inquiry skill and knowledge achievement were examined before and after the interventions. As results, the experimental groups showed more significant improvement on the areas of the students' creativity, scientific thinking, scientific inquiry skill and achievement than the control groups. Results indicated that the specially designed modules in terms of hypothetical-deductive experimental procedure were effective to improve science high school students' creativity and scientific thinking abilities.

  • The purpose of this study is to acquire the information on the current situation of students' selection process in order to renovate the system of picking up the students. As a first step of the study, we examined the validity of the factors of the single-out system such as qualification and the process for the application and the standards and proceeding of the selection. Then we analysed the result of the entrance examination of Hansung Science Highschool in 2002. The analysis was on the correlation between the result of entrance examination and the achievement in the school and the decision of the course after graduation. To know on the achievement of the students, we investigated the records of regular tests and asked the teachers' opinion in math and science classes. As a result, we gained the following points: First, the present single-out system has a danger of excluding students who are much talented in science and math field because it is based on students' achievements in middle schools; Second, the new selection system should consider the character and attitude of the applicants in addition to their knowledge; Third, the continuous observation of the teacher in middle school should be an important factor of the picking up system; Fourth, more questions requiring divergent thinking ability and inquiry skill should be developed as selective examination question. Also examination questions should cover the various contents from mathematics to science, and do not affect pre-learning; Finally, the system of present letting all students stand in one line should be changed into that of letting students in various lines. We can consider using multi-step selection system.

  • The Necessity and Purpose of the Study Recently the number of patients with chronic diseases and the aged patients is increasing steadily. Furthermore, due to the expansion of health insurance system, the number of patients hospitalized in the general hospital is increasing at a surprising speed. However, hospitals urge the early discharge of the patients for the efficiencies of hospital administration, and therefore, the number of patients who must be taken care of in their home is also increasing. Homecare nursing is one of the health care service for the patients at home who require continual attention and care, and now increasing attentions are given to it as one of the professional nursing fields. However, it was almost impossible to find a study on the actual experiences of the homecare nurses written by their own language in Korea, that it also posed a great difficulty in understanding their diverse experience. Considering these situation, this study will help understanding of them, and provide the fundamental data on their experiences for making policies to develop homecare nursing. Methods of Research Phenomenological research method was employed to analyze the lived experiences of homecare nurses fundamentally. Data collection Data were collected from August 1998 to December 1998 from ten homecare nurses who worked for patients under the homecare nursing setting as model cases designated by Seoul Nurses Association and who agreed to the purpose of this study after listening to and understanding the explanation completely. The in-depth interview was carried at the time which was convenient both for the researcher and participants for one or two hours, and recovered with the approval participants. The first interview covered diverse and broad areas like the situation of homecare nursing, and their feelings and thoughts over it, and in the second and third interviews, more specific questions are asked. Data Analysis For the phenomenological analysis, contents analysis was employed. The data collected from the participants were analyzed into the following procedures according to Van Manen 's phenomenological analysis. 1) Reserve the preconception of the researcher by restricting it inside parenthesis. 2) Make a thorough observation of the lived experiences by insight process. 3) Analyze the contents (Find out the repetitive factors) 4) Interpret the essence found. 5) State the meaning of the interpretation. Results and discussion 1. Fear and expectation for the first visit. (unfamiliarity, awkwardness, anxiety, shivering) 2. Mingle with the family (feeling friendly with the family, becoming like a family member) 3. Being proud of her own know-how (learning the know-how, organizing alternatives, building up confidence) 4. Pity for the poor. (criticizing the current government, feeling ashamed, feeling anger) 5. Difficulty of constructing cooperative system with physicians (strenuousness, frustration) 6. Helplessness due to the lack of support system (difficulty to get supplies, annoyance, embarrassment by institutional restraints) 7. Anxiousness for heavy traffic and parking (annoyance, hastiness) 8. Ethical conflicts (pity for the patients and family, skepticism about lengthening life maintenance) 9. Burden for the possible accident (pressure, anxiety, conflict, physical exhaustion) 10. Establishment of identity as a professional (fulfillment, worth, joy) 11. Being distressed at other's ignorance

  • The main goal of this research is to invest the difficulties in the process of developing serious game for science learning to acquire the suggestion. We analysed the journals written by developers of game scenario on the procedure of the development and on the review of the accomplished game. Then we also interviewed the scenario developers as well as game developers. When interviewing the game developers, we passed them the thoughts and questions of scenario developers. The possible difficulties in developing serious game are form the difference of cognitions on the skills which can be embodied in the development process and interaction and communication problem between scenario developers and game developers. As a consequence of the research, we acquired some suggestions for developing serious game as follows; 1) Scenario developers and game developers must understand the concepts of serious game as well as learning theory; 2) Both scenario developers and game developers should be aware of secured technological capacity and allowed time period. 3) Scenario developer should take a part of game developer' role as using a learning contents authoring tool; 4) Scenario developers have to consistently interact with game developers in developing the games; 5) Scenario should be concretely described in detail; and 6) A Supervisor is essential to control both scenario developers and game developers.

  • By analyzing and integrating established geological field study instances, this study offered a new geological field excursion teaching model with several steps: unifying question raising. excursion generalization. intensive field direction, searching, primary conclusion, re-searching, group discussion. adjustment, and excursion summarizing. Then by Qualitatively assaying the responses which students showed after applying this teaching model, a concrete teaching plan was sought for earth science teachers who were planning to begin geological field excursion classes. Students evaluated very highly on the unifying question and excursion generalization because these items provided a sense of direction and an overall theme for geological excursion in advance. Also. since the students had little to none geological knowledge and field excursion experience, the intensive field direction gave them a lot of help with their field excursion activities. Students thought that coming up with a primary conclusion based on the summary of what they had observed in their activities was original. and highly valued the process of sharing different opinions in group discussions and drawing out a final conclusion. Teachers should help students develop a friendly atmosphere, by organizing group activities and continuously feedlng them with uniting questions and excursion generalization within the groups. Also they should prepare enough contents for intensive field direction and ways to get their points across. In the process, they should arrange beforehand detailed instructions for every outcome, with the intention of solving the question. Furthermore. teachers should follow carefully how conclusions are drawn. instruct students not to reach conclusions based on mere assumptions, and be aware of misconceptions students have toward geological phenomenon in advance, so that the discussion can be lead in the right direction.
