This study investigated the influences of applying the Cognitive Conflict Process Model (the Procedural Teaching Model using Cognitive Conflict Strategy: Kwon, 1989) upon students' achievement and attitudes in a middle school science concept instruction. For the treatment group, science instruction to apply the Cognitive Conflict Process Model was used. For the control group, traditional instruction was used. Prior to instruction, students' pre-conceptions test and attitudes test related to the science were administered. After instruction, the above two tests and the regular examinations were measured. Also students' perceptions of their teacher's new teaching style was investigated by questionnaire. But, above all, the main purpose of this study was to investigate the principal accompanying matters of general application of the teaching model to science concept instruction rather than conceptual and attitudinal change. Therefore, this study identified necessary conditions of applying the teaching model to science instruction.

In this research, we investigated the support system and professional development in teaching practices of beginning science teachers through instructional consulting. Using open-ended interviews with the participating teachers and group discussions taking place on a regular basis to analyze and compare classes of six beginning teachers, we analyzed beginning teachers' professional development efforts centering around their teaching practices. The group discussion consisted of 6 beginning teachers and another 6 experienced teachers, they discussed and cross-analyzed beginning teachers' 9th lessons on middle school science unit, 'Work and Energy.' The characteristics of beginning science teachers' professional development drawn from this research are: (1) beginning teachers' teaching practices they were taught, (2) lack of reflection on their teaching practices, (3) no guidance for beginning teachers regarding ways to teach, (4) lack of communication between teachers about teaching science, and (5) lack of time for instructional preparation due to other heavy workload. Suggestions for ways to improve and support beginning teachers' professional development are discussed with experienced teachers. Required conditions for an effective induction program are also discussed.

This study aims to develop teaching materials for scientific creativity and to introduce it in more detail. To do this, based on the analysis of the previous studies, we developed about 80 activities in five categories. Main features of the developed materials are as follows: (1) it covers various areas of creativity, (2) each activity includes elements of scientistic creativity, (3) each activity includes guides for thinking creatively and instances of the guides, (4) these guides are categorized to be utilized in other situations for teaching creativity, (5) the activities can be transformed according to actual teaching situations. The teachers gave responses that materials were appropriate to teach scientific creativity and that they wanted to use the materials in schools. And based on the teachers' response about the advantages, disadvantages, and conditions for more effective use of the materials, we hope that further studies for actual use and revisions on the materials will be conducted. Finally, we suggested various methods to use the developed activities for different purposes and educational situations.

At the present stage, the main directions of the professional position of a specialist in the implementation of English-language Education are to improve and spread the practice of learning languages throughout a person's life by involving information, communication and digital technologies in the educational process. Computerization of the educational process in Higher Education Institutions is considered as one of the first and most promising areas for improving the quality of education in Higher Education Institutions. The necessity of ensuring timely training and retraining of specialists of various profiles (in particular teachers) on the effective use of domestic and foreign electronic resources with the help of modern information technologies for the implementation of the professional position of a future specialist in a foreign-language environment is noted. The main goal of teaching a foreign language (the formation of students' communicative competence, which means mastering the language as a means of intercultural communication) is defined. The types of speech activity that cover the content of teaching a foreign language are highlighted. The main types of assessment in a foreign language are shown - current (non-classroom), thematic, semester, annual assessment and final state certification. The task of the teacher is drawn, which is to create conditions for practical language acquisition for each student, to choose such teaching methods by means of information technologies that would allow each student to show their activity, their creativity; to activate the cognitive activity of the student in the process of learning a foreign language.

This research attempts to establish a strategy through which to secure the introduction of the KEM 2.0 system. Another aim of this research is to eventually establish a service system which can be used to automatically generate and provide the metadata information contained in the Cylearn system. in order to facilitate Korean vocational high school students access to teaching-learning materials. The main research tasks associated with this research were: 1) To establish the components of the file server system while taking into consideration the environment in which each educational organization operates; 2) To utilize the KEM 2.0 in order to optimize the configuration of the Cylearn system and the related software. To do so, the KEM 2.0. should be applied in close coordination with Edunet: The results of this research can be summarized as follows: First, a strategy to introduce the KEM 2.0 was established. To achieve this, the researcher analyzed the characteristics of the sequencing and presentation methods and suggested teaching-learning materials based on the KEM 2.0.s sequencing system. Second, the file server was constructed using the KEM 2.0. The established file server took into account the environmental conditions in which the Edunet system operates so as to facilitate the creation of a network system with Edunet. Third, the Cylearn service system was linked to Edunet. The researcher developed a module using the KEM 2.0. that could be used to transmit the metadata related to teaching-learning materials to Edunet. To achieve this, an input device and a databank which could be used to transfer the generated metadata to Edunet were developed. The input device and databank developed using the KEM 2.0. were used to transfer the metadata to Edunet by linking the Cylearn system to the Edunet system.

When teaching English in elementary schools was introduced in Korea in 1997, the theoretical basis was the critical period hypothesis (CPH). The object of this study was to test whether the Korean situation satisfies the conditions for the CPH such as the amount of English input and needs. As a test for this, English input and needs were compared in Korea, the U.S.A. and Singapore. The items for English input were on a continuum of primary to secondary sources and the items for English needs were on a continuum of immediate to future needs. The 0-5 scale was used. The result showed that the total means of English input were 4.87, 4.62, and 1.05 for children in the U.S.A., Singapore and Korea respectively. The total means of English needs were 4.32, 3.81, and 1.52 for children in the U.S.A., Singapore and Korea respectively. These figures show that Korean children's levels of both input and needs were from “almost none” to “little,” while those of children in the U.S.A. and Singapore were from “much” to “very much.” This shows that teaching English in Korea presently is far from meeting the conditions that are expected by the CPH. As an alternative to explain what happens cognitively to Korean children, this paper suggests the automatization and proceduralization processes.

The differential quadrature (DQ) and teaching-learning based optimization (TLBO) methods are coupled to introduce a hybrid numerical method for maximizing fundamental natural frequency of laminated composite skew plates. The fiber(s) orientations are selected as design variable(s). The first-order shear deformation theory (FSDT) is used to obtain the governing equations of the plate. The equations of motion and the related boundary conditions are discretized in space domain by employing the DQ method. The discretized equations are transferred from the time domain into the frequency domain to obtain the fundamental natural frequency. Then, the DQ solution is coupled with the TLBO method to find the maximum frequency of the plate and its related optimum stacking sequences of the laminate. Convergence and applicability of the proposed method are shown and the optimum fundamental frequency parameter of the plates with different skew angle, boundary conditions, number of layers and aspect ratio are obtained. The obtained results can be used as a benchmark for further studies.
