In this study, we investigated the thinking processes of 7th grade science-gifted students in designing application experiments and analyzed their performance levels in the categorized processes. The analyses of the results revealed that they considered 'setting a problem situation,' 'deciding a strategy,' 'identifying the assumptions,' 'defining the measurements,' and 'validating the assumptions' in the processes of designing experiments. However, their performance levels of the categorized processes were found to be rather low. It was especially insufficient in setting the situations concretely appropriated to solve the problems and checking their own thinking critically by proper criteria. Therefore, we suggested a potential learning strategy for designing experiments such as replacing difficult and abstract situations to concrete and familiar situations. These results may offer some implications in developing an education program for science-gifted students to foster creativity by emphasizing scientific thinking skills such as experiment design ability.

This study was conducted with two 6-graders to identify how were their proportional reasoning abilities, whether they evolved proportional thinking in a various context, and what had influence on their proportional thinking. The findings, as previous researches noted, suggested that the proportional expression obtaining by instrumental understanding could not provide rich opportunities for students to improve understanding about ratio and proportion and proportional reasoning abilities, while being useful for determining the answers. The students were able to solve proportional problems with incorporating their knowledge of divisor, multiples, and fraction into proportional situations, but not the lack of number sense. The students easily solved proportional problems experienced in math and other subjects but they did not notice proposition in problems with unfamiliar contexts.

The purpose of this study is to analyze how the teaching activities which used EXCEL influence the specialized high school underachieved students. They have difficulties in making use of various representations for better understanding of function. EXCEL is helpful for learning function because it enables the students to use real life materials in math learning as well as formulates Tabular, Algebraic and Graphical which represent function. Furthermore, the students in specialized high school also have the experience of using EXCEL while studying other subjects. For that reason they have no burdens and fears on using EXCEL in learning activities. Utilizing EXCEL in the classroom gives an expectation that it helps to have interests on studying function and prepare for the next learning in the end. Research classes were conducted in a group of five students who have different hopes of career and a variety of mathematical interests. Though the students couldn't transfer Algebraic to Graphical in the diagnostic evaluation, they could resolve the problem of connections between Graphical, Tabular and Algebraic in the process perspectives, and could also express graphical representation by linking object perspectives with process perspectives. Therefore, they solved the connection problem of Tabular, Algebraic and Graphical in the object perspectives. As a result, the students could make transitions between Algebraic and Graphical in object perspectives through the classes applying EXCEL. Consequently, teaching the students with underachievement utilizing EXCEL enables them to recover their interests on math and it helps them to complete their following curriculum.

This study presents how the engineering ethics instructional modules have been developed based on Korean culture and how they are implemented into the existing engineering curricula at Sungkyunkwan University. The engineering ethics instructional modules were designed to be taught by engineering faculty members who did not have any teaching experience in ethics. As a result, it was determined that the engineering ethics instructional modules should include a detailed instructor lesson plan and all supporting resources such as slides (Power Point base), and handouts, or assessment units (pre- and post-test). Two 75 minute modules developed in this study consist of the diverse instructional activities for various student group sizes. In order to improve students' interests and classroom attention, various visual and audio resources such as famous movies, cartoons, and poems were included in the instructional resources. In addition, a number of case studies which might happen in the students' daily lives were chosen. The resulting ethical module No. 1 has been instructed in the existing engineering classes during the 1st semester in 2007. Overall, the students reported positive impressions of the modules and the faculty members also reported favorable perceptions of the modules. Also, team based activities encouraged students to participate in constructing the event trees, which are a basic analysis tool for ethics case studies. The results of this study will provide a guideline of implementing engineering ethics into the engineering curricula to other engineering programs and schools.

This research analyzes the character factor in picture book, so the purpose is to develop the early childhood character program through Nuri curriculum. Picture book is the most familiar media for childhoods, and we are available it naturally in our lives. For this first, we analyze 6 elements(consideration, respect, cooperation, sharing, order, filial duty) in teacher's guide of the Nuri curriculum. Next, consulting the analyzed factors, the 12 picture books which will be utilized this program are chosen by the standard like literary, artistic, educational value. The chosen picture book devised total 12 times education plan to design each 2 times education plan in the factors for teacher's guide of Nuri curriculum. Lastly, it was finally developed through validation process by 2 teachers and 2 the professors of early childhood education. The developed program is needed later field application and It is required of the effectiveness verification after we apply 12 times activities on each age of childhoods for 3 to 5 years od in education field, so it may improve elements like consideration, respect, cooperaion, sharing, order, filial duty as childhoods experience this program personally. Also, this can provide it to teachers in childhood eucation field as study guidance plan.

This study aims to identify what kind of epistemological resources were activated in unproductive and productive practice by students participating in scientific argumentation, and to explore which contexts result in changes in argumentative practice. We collected transcriptions of participants' argumentative lessons and interview, participants' work sheets, and researchers' field notes. The analysis revealed that the focus group activated different kinds of epistemological resources depending on their practice; propagated, belief, and accumulation in unproductive practice and constructed, understanding, accumulation, formation and rebuttal in productive practice. We found two contextual cues that led to these changes; unfamiliar form of argumentative task was provided and emotional, epistemic, and conceptual support of the epistemic authority. This work can be provided as additional case studies to analyze changes in practice according to learner context-dependent epistemology, and we expect to contribute to discussions of productive epistemology and stabilization for students' authentic science engagement.

To understand the use of the ebooks among undergraduate students, a questionnaire was devised and collected data from 466 respondents. The level of ebook and its service awareness appears to be low, and only about 30% of the students have used ebooks in the past. Students access ebooks primarily through the library homepage. 73% of the users read 3 ebooks and below. The subject and area of reading is fairly spread, however literary works and genre fiction were most popular And the purpose is split into academic and private reading. Most of the users lack of knowledge about additional functions. Overall satisfaction level is low. Discomfort and ebooks illiteracy constitute the major reasons of nonuse, however about 88% of the nonusers show willingness to use in the future. According to the interview, active users are familiar with the screen reading as well as perceived advantages of ebooks. Nontheless, their satisfaction level is still low. Based on the results, recommendations for creating awareness, education, production development and service evaluation are suggested to promote the ebooks use.

Recently, scientific literacy means not only the acquisition of scientific knowledge but also the linguistic ability to participate in a scientific discourse community. Keeping this in mind, this study investigated middle school students' writings about phase transitions of water in air. Sixty seven students at 9th grade (age 15) students participated in this study and wrote two individual short texts. The result of text analysis can be summarized as follows: (1) students had problems with familiar scientific terms such as 'water vapor' and 'steam' as well as unfamiliar ones like 'dew point'. (2) Students described right semantic relations and at the same time wrong ones more in the idea formed from everyday experience than those from school instruction. (3) While students showed action and process centered writing in text about everyday phenomenon, they showed more preference for technical words and nouns in text about school science. This study suggest that students could develop linguistic ability of science from both spontaneous process based on experience and formal and theoretical learning; the former in forming various semantic relations, the latter in technical and abstract aspect of scientific writing.
