The purpose of this study was to suggest a grounded theory on the process of undergraduate students' generating pattern-knowledge about scientific episodes. The pattern-discovery tasks were administered to seven college students majoring in elementary education. The present study found that college students show five types of procedural knowledge represented in the process of pattern-discovery, such as element, elementary variation, relative prior knowledge, predictive-pattern, and final pattern-knowledge. Furthermore, subjects used seven types of thinking ways, such as recognizing objects, recalling knowledges, searching elementary variation, predictive-pattern discovery, confirming a predictive-pattern, combining patterns, and selecting a pattern. In addition, pattern-discovering process involves a systemic process of element, elementary variation, relative prior knowledge, generating and confirming predictive-pattern, and selecting final pattern-knowledge. The processes were shown the abductive and deductive reasoning as well as inductive reasoning. This study also discussed the implications of these findings for teaching and evaluating in science education.

The purpose of this study was to analyse the belief about mathematics teaching of elementary preservice teachers and mathematics teachers. This study involved 100 respondents from the preservice teachers and 114 respondents from the mathematics teachers. The instruments used in this study consist 15 items of mathematical knowledges and 19 items of mathematical activities. The finding showed that preservice teachers emphasized the conceptual knowledge, whereas mathematics teachers emphasized the procedural knowledge in the mathematical knowledges. And preservice teachers emphasized the knowledge representation, knowledge generation, knowledge deliberation, knowledge communication, whereas mathematics teachers emphasized the use of knowledge(syntax) in the mathematical activities. Finally, even though two groups showed the significant difference in some items, preservice teachers and mathematics teachers emphasized the various mathematical knowledges and mathematical activities.

This study aimed to explore how to characterize the earth science inquiry in schools in terms of science teaching interaction and constructivist teaching practice. The constructivist teaching practices were analyzed with Reformed Teaching Observation Protocol (RTOP) in three aspects including (1) student oriented class implementation, (2) subject knowledge and representation, and (3) classroom communication. Fourteen earth science classes were observed and scored with RTOP. The class was evaluated to be transitional stage in terms of constructivist teaching, e.g., moving toward student-centered teaching practice. Especially, Korean teachers tend to lean their classes more on propositional knowledge than procedural knowledge. To interpret science teaching interactions, an earth science teacher with a RTOP top rank was selected. Her class was then videotaped for detailed analysis. I adopted the analytical framework of communicative approaches and discourse patterns among the five aspects of interactions presented by Mortimer and Scott (2003). It was found that this earth science teacher used more authoritative patterns than the dialogic. In addition, she used IRE discourse pattern more frequently. Interestingly, teachers interacted with their students more frequently in the form of repeated (or IRE chain pattern), that is IRFRF (teacher initiation-student response-teacher feedback-student response-teacher feedback) in the context of dialogic communicative approaches, while simple IRE occurred in an authoritative approach. In earth science classrooms, typical interaction may well be constructed in the form of IRFRF chains to allow students free conjectures and abduction.

This study aims to identify the characteristics of gas phase problem solving of college freshmen. Four students were participated in this study and solved the problem by using think-aloud method. The thinking processes were recorded and transferred into protocols. Problem solving stage, the ratio spended in each solving stage, solving strategy, misconceptions, and errors were identified and discussed. The relationships between students' belief system about chemistry problem solving and problem solving characteristics were also investigated. The results were as follows: 1. Students felt that chemical equation problem was easier than word problem or pictorial problem. 2. When students had declarative knowledge and procedural knowledge required by given problem, their confidence level and formula selection were not changed by redundunt information in the problem. 3. When the problem seemed to be difficult, students tended to use the Means-End or Random strategy. 4. In complicated problems, students spent longer time for problem apprehension and planning. In familiar problems, students spent rather short time for planning. 5. Students spent more time for overall problem solving process in case of using Means-End or Random strategy than using Knowledge-Development strategy.

This study aims to suggest a model and instructional strategies for a flipped classroom using First Principles of Instruction in engineering education in order to organize teaching and learning activities in a flipped classroom. For this purpose, the authors analyzed the literature on the flipped classroom in engineering education and on applying First Principles of Instruction in designing flipped classroom. Then, a framework of flipped classroom employing First Principles of Instruction and instructional strategies were suggested. Two experts examined the validity of the model and of the instructional strategies, and the final version was completed reflecting on those feedback. Since engineering education aims to teach procedural knowledge as well as conceptual knowledge, different instructional strategies upon two types of knowledge were presented. The implication of our work is to illustrate the model and tactics for flipped classroom based on the Merrill's deeply rooted pedagogical approach. This study may contribute to practice in engineering education.

Purpose: The purpose of this study was to examine the nurses' knowledge and attitude to pain management in children and explore the status of pain management in clinical practice. Method: The subjects were 131 nurses enrolled in 3 university affiliated hospitals. Questionnaire method was utilized for data collection. Data was analyzed by SPSS statistical program. Result: The result was as follows: 1. The overall mean score of the pain knowledge was 16.88 (58.2％). The percentages of correct response in test subsections were pain assessment 45.5, choice of medication and drug action 48.7, and pain statement 79.6 respectively. 2. 70.3％ of the nurses agreed or strongly agreed that the procedural pain should always be eliminated. And, 44.3％ of the nurses agreed or strongly agreed that post-operative treatment of pain in children should always aim at eliminating the pain completely. 3. There was a significant relationship between pain attitude and knowledge related facts about pain(r=.217, p<.01). 4. When asked to identify the point of self-reported pain on a 0-10 scale at which the nurse would give medication, point 7 was mostly identified (29％). 5. Only 19.8％ of the nurses utilized pain rating scale to assess children's pain. 6. The nonpharmacologic interventions nurses used most were position change, emotional support, and massage. 7. 68.7％ of the nurses indicated that they learned about pain management from their current working environment. Also, Mostly helpful resource identified in increasing their pain management knowledge and skills was the continuing education program. Conclusion: The findings showed that there was a need to develop educational program for adequate pain management for children. Further research study is recommended to examine the effectiveness of the intervention methods for children's pain.

Many elementary school teachers' lack of scientific knowledge reveal as several problems in teaching science. Thus, elementary school teachers need to improve their scientific knowledge, but there is the limit to improve the teachers' scientific knowledge through activities based on lecture that conducted in process of training and retraining them. Therefore, Improvement for training science teacher to improve scientific knowledge of elementary school teachers would be searched in this study. Depth interview was conducted toward three elementary school teachers, who had conducted action research, to improve content knowledge of material domain within teaching process and elementary school science. Based on result of the interview, difficulty and development that the three teachers were commonly experienced in process of conducting scientific inquiry in action research were analyzed. One of the difficulties of the inquiry were to figure out how the three teachers, who participated in the interview, understand specific concept, what they do not understand, and what they should study more to understand the concept. And there was a circumstance that the teachers did not know how to apply procedural knowledge, which learned explicitly in the process of setting plan for conducting research, into real context. Since there was difference between knowledge that they understand disjunctively and context that observed in real circumstance, they faced difficulty. However, the teachers conducted analysis of topic, planning research, conducting research, discussion of the result by themselves with those difficulties Thus, the teachers mentioned that not only content knowledge had been improved, but understanding of procedural knowledge, which is not intended to improve, had been also improved. Besides, they also mentioned that comprehensive understanding content knowledge, which they already understood, was also helpful. And the teachers suggest that if there were chance to discuss and examine the scientific practices by consisting of group with colleagues rather than conducting it individually it would more efficient studying. Considering their suggestion, direction of training elementary school teachers for improving their scientific knowledge should be improved in a way to understand science concepts based on direct research about context that is generated in circumstance of studying group of the teachers. Consequently, it would contribute to improvement of teaching science by combining teachers' practice and understanding.

It needs theoretical assessment fundamental for informatics curriculum to judge appropriate grades and measure academic standard of an learner according to be included in the conventional curriculum. Thus this study tried to present an criteria on programming area of an informatics curriculum through bloom taxonomy and knowledge type. And it presented assessment criterion on each steps from "Remember" to "Create". And we presented knowledge type examples of programming such as Factual to Metacognitive based on Bloom's knowledge types. Also we analysed that most important level or type is Apply Level, Create Level and Procedural Knowledge. We investigated for each criterion of programming assessment based on bloom's theory through Delphi method. And the result of this investigation was that area of bloom's taxonomy was CVR 0.90, Validity 0.85 and area of knowledge type was CVR 0.90, Validity 0.79. So it can decide to accept for our assessment criteria of programming education based on Bloom theory.

This study intended to draw some suggests for the development of mathematics teachers' expertise through the comparison research of pre-service and in-service teachers' PCK about questioning in elementary mathematics class. For this purpose, questionnaire survey was conducted to some pre-service and in-service teachers about the PCK concerning the way how questioning during mathematics class. This survey revealed the following implications. First, from the perspective of mathematics classroom, it is still more important the practical knowledge about how to teach which is evolutionally developed passing through the experience and currier of teaching than theoretical knowledge itself. Comparing the teachers' PCK about the two related knowledge types of mathematics contents, in case of procedural knowledge related PCK it was more asked of teachers' expertise than the case of conceptual knowledge related PCK. Thirdly, in case of learners' incorrect answer, for the desirable teaching it should be a questioning focused on whether there being or not the systematic among the learners' incorrect answer, and in case of appreciating the learners' understanding about the presently taught contents the questioning should be constructed considering the relevant contents early learned.
