  • The purpose of this study was to analyze the types of teachers' questioning between verification laboratory instruction and discovery laboratory instruction. Results were that there was no difference in questioning types in verification laboratory instruction and discovery laboratory instruction. Most teachers in two types of laboratory instruction used closed questionings more than open-ended questioning. This shows that teachers' laboratory instruction processes are focusing on 'get the content' rather than consideration of the characteristics of laboratory instruction types. Such results show that the teachers in verification laboratory instruction and discovery laboratory instruction provide little opportunity for children to improve in scientific thinking. Therefore, teachers should make good plans with a questioning strategy that can be adapted to the types and characteristic of laboratory instruction. If teacher's questioning is practiced well in the science class, it can improve students' scientific thinking and science laboratory instruction.

  • The purpose of this study was to develop a classification scheme for laboratory instruction, which could occupy a central and distinctive role in science education. For this study, literature on laboratory instruction types were analyzed. Utilizing several of these theoretical frameworks, a Classification Scheme for Laboratory Instruction (CSLI), which clearly represents various features of laboratory instruction, was created. The developed CSLI consisted of two descriptors: one is the procedure for laboratory instruction, and the other is a way of approach. The procedure is either designed by the students or provided for them from an external source. A dichotomy also exists for the approach taken toward the activity: deductive or inductive. Validity was established for the CSLI. In addition, laboratory instruction according to CSLI was divided into four types: verification, discovery, exploratory, and investigation. Although this study demonstrated only limited features of laboratory instruction due to the absence of a field test, it serves as a model for more comprehensive studies.

  • The purpose of this study was to identify the main laboratory instruction types with Classification Scheme of Laboratory Instruction (CSLI) in elementary and secondary schools science. For the purpose, the validity of the instrument CSLI was 4.23 and laboratory instructions were collected in 100 elementary schools and 30 secondary schools. Before analyzing the collected laboratory instructions, the inter-rater reliability about the analysis results was identified as 0.91. The results of this study were found that in elementary school, the main laboratory instruction types were verification type and discovery type and in secondary school were discovery type and verification type. In the category of the procedure, a large part of the procedures of laboratory activity in both elementary and secondary schools was given to students by worksheets or teachers themselves. In the category of approach, inductive approach was the main in elementary and deductive approach in secondary.

  • The purpose of this study was to investigate high school students' learning style, perception of types of laboratory instruction, and the relationship between the learning style and preferred type of laboratory instruction. The participants of this study were 19 female high school students, from Incheon in Korea, who showed outstanding science grades. Dunn et al's revised Learning Styles Inventory (1997) was used for testing students' learning style. The students were asked to choose preferred and not preferred types of experiments and describe the reason of the choices after implementation of 4 types of experiments: verification, discovery, explorator, and investigation laboratory instructions. The findings of this study were as follows: Firstly, the students had a certain common learning style irrelevant to their personal characteristics, i. e; they showed high (self, teacher, parents) motivation and structure stimuli that was common in Korean students. Second, outstanding students prefer unstructured and open laboratory instructions. And those students were highly influenced by sociological and emotional stimuli. Third, students' learning style was related to their preferred type of laboratory instruction. Students preferring unstructured and open laboratory were influenced by sociological and emotional stimuli, while those preferring structured and closed laboratory were influenced by physiological stimuli.

  • The purpose of this study was to compare the effectiveness of programmed instruction versus lecture and discussion method on the knowledge of basic reference sources among undergraduate library and information science students. The hypotheses of the study were: 1. Programmed instruction will be more effective than the lecture/discussion method with regard to academic achievement. 2. There will be a significant difference in learning time between the experimental and the control groups. Seventy-eight library and information science students were participated m the study from the two universities in Chungchong Province. A programmed instruction manual, including 4-types of reference sources-dictionary, encyclopaedia, bibliography, indexes and abstracts, 40-item multiple choice post-test, and a questionnaire for the students' attitude toward programmed instruction were developed specifically for this research. The post-test only control-group design was selected for this experimental study. Students were given instruction on the specific reference titles in dictionary, encyclopedia, bibliography, indexes and abstracts. The control group was instructed by the lecture and discussion method while the experimental group completed a programmed instruction manual by themselves. Both the control and the experimental group were tested right after the instruction of 4-types of reference sources. In addition, a questionnaire asking students' attitude toward programmed instruction was administered to the experimental group. The findings from this study are summarized as follows: 1. The results showed that there were no significant difference in the mean of the post test score between the two groups. Therefore, programmed instruction is viable as an alternative method of instruction in the teaching of reference sources. 2. There was a significant difference in the mean of time spending for the leaning of bibliography, indexes and abstracts between the two groups. Accordingly, programmed instruction proved to be more efficient than the conventional lecture/discussion method in terms of learning time. 3. Students showed positive response to programmed instruction and evaluated it very interesting and challenging. In conclusion, the programmed instruction method was just as effective as the lecture/discussion method in the teaching of reference sources. And students' attitude toward the programmed instruction was favorable enough to secure a continued use of this method for the teaching of reference sources.

  • The purpose of this study was to describe the elementary teachers' teaching behavior procedure in verification-type laboratory instructions. In order to do this, we should know first what constituted the teaching behavior elements in the teachers' instructions, before the teaching behavior can be analyzed. Thirty sets of instructions were recorded and their transcripts were used in this study. The results of this study indicated that the number of teaching behaviors numbered twenty four in total, and that the teaching behaviors could be classified into nine categories, and finally the procedure used in verification-type laboratory instructions generally followed seven steps. These steps can be described as follows; reminding subjects of the preliminary learned concept, presenting inquiry type questions or introducing the main concept, explaining the method used or presenting the predictable outcome/matter for verification, performing lab-based activities, presenting the outcomes, applying the main concept, and finally closing the instruction. For the purpose of promoting more authentic scientific inquiries using these types of instructions, the authors's claims were discussed.

  • Introduction This study is concerned with improving the nursing education curriculum. The purpose of the study was to 1. Review the basic principles of curriculum development. 2. Determine opinion about current nursing curriculums from recent nursing school graduates. Methods of the study A questionnaire was distributed to 250 nurses, in f general hospitals in Seoul. The nurses were graduated from nursing schools in 1973, but represented all types of nursing programs. The Questionnaire was designed to illicit responses about nursing school curriculums in 5 areas: 1. Establishment of objectives 2. Selection of learning experience 3. Organization of learning experience 4. Instruction 5. Evaluation Summary of the major findings 1. Establishment of objectives Thirty nine point three percent of the nurses said that the first objective of the general nursing education was stated "to educate a nurse as a human being with humanity:" Ninety point eight percent of the total respondents said that thor knew the objectives of the curriculum of their nursing schools, but more half of them (58.3%) understood the objectives vaguely at the time they attended nursing school. 2. Selection of learning experience Thirty nine point eight percent of the respondents said their curriculum contained "only a few" liberal arts courses. 3. Organization of learning experience forty seven point six percent. of the respondents were reported that the number of course hours was "insufficient" in liberal arts courses. Fifty seven point three percent of the nurses felt there was an overemphasis on any special topic in liberal arts courses. 4. Instruction Methods of instruction were as follows: Liberal arts courses-a. lecture which centered on explanation (61.1%), b. lecture which centered on writing (43.7%) Supporting nursing courses-a. lecture which centered on explanation (34.0%). b. laboratory Practice (37.8%) Clinical nursing courses-a. lecture which centered on writing (33.0%), b. clinical practice (38.4%) The percentage of respondents replying that various equipment for the learning activities were "insufficient"were as follows: Liberal arts courses-51.0% Supporting nursing courses-28.6% Clinical nursing courses-37.9% 5. Evaluation In the liberal arts courses, 30.6% o( the respondents answered that the evaluation of records was in their opinion "poor, " and 28.2% of the respondents reported that the method of evaluation was "unfair and discouraging. " "Development of a systematic theory of nursing" was thought to be essential for curriculum improvement. The respondents felt that the junior year was the hardest because 1. Number of subjects was too great (28.1%) 2. Lack of a systematic theory of nursing (14.5%) 3. Conflict due to the difference between nursing theory and nursing practice (21.4%) Recommendations 1. Since this study was limited to nurses who had graduated in 1973, a larger study involving professors, graduate students, and nurses from a wider area is suggested in order to establish the reliability and validity of the present findings. 2. Nursing research should be carried out more actively in order to develope nursing science. 3. A permanent organization for research into ways to improve the curriculum should be established in each nursing school.
