The School of Mathematical Sciences at University Sains Malaysia has offered a laboratory course on the integration of hand-held technology into the teaching and learning of mathematics since the beginning of the 2001/2002 academic year. This inquiry-based course highlights the explorations and application of mathematics in a data rich modeling environment. In addition, the course addresses several issues related to the effective integration of such technology into the mathematics curriculum. This paper discusses the appropriate use of graphing technology to present mathematical concepts and to support student's understanding in a student-centered learning environment, shares knowledge on the new mathematics that was made possible by hand-held technology, and summarizes student reactions to this innovative learning mode.

The use of holographic standardized patient (HSP) with mixed reality can provide students with the opportunity to enhance clinical reasoning skills. This is still relatively new, so there is a lack of guidelines for educators. Thus, we aimed to develop the instructional model of HSP-based education, for enhancing clinical reasoning skills in undergraduate healthcare education, which could systematically guide educators in designing and implementing HSP-based teaching and learning activities appropriately. Using a design and development research, a theoretically constructed initial mode in this study was iteratively improved and underwent validation through expert review and model usability test. Features of the model were discussed, along with theoretical and practical implications and suggestions for further research.

Science-Technology-Society curricula have been developed in several countries for the last 20 years. Those curricula were focused on social aspects of science, i.e., value-laden knowledge and scientific enterprise, and society-related scientific and technological issues, i.e., energy, pollution, natural resources. The major teaching models employed in those curricula were problem solving and decision making, which required the following teaching techniques: teacher as a manager, small group discussion, controversy as a motivational force for substantive learning, and sufficient factual information into the discussion. Further researches are to be made to ascertain whether or not the expectations of the curricula might be realized in practice. It was shown that most Korean biology teachers considered the STS-related goal of science education as more important than the other goals. Based upon the findings, some recommendations for development of Korean STS curriculum were made as follows: 1. The contents of the STS curricula are to be organized with the integrated mode; 2. The major teaching models throughout the contents are to be problem solving and decision making. These are considered to provide students with the opportunities to involve in debates on practical issues and to draw consensus from them; 3. Some degree of flexibility should be provided on teachers' implementation of the curriculum in terms of contents, teaching techniques etc.; 4. To increase the practicality of the curriculum, teachers should be involved in the development of the curriculum and the relevant research; and 5. Contents to be included in STS curriculum were suggested by some science educators, but the more systematic study is required in this respect.

The purpose of the present study is to present a new approach to designing and selecting the details of multidimensional continuous RC beam by applying all strength, serviceability, ductility and other constraints based on ACI318-14 using Teaching Learning Based Optimization (TLBO) algorithm. The optimum reinforcement detailing of longitudinal bars is done in two steps. in the first stage, only the dimensions of the beam in each span are considered as the variables of the optimization algorithm. in the second stage, the optimal design of the longitudinal bars of the beam is made according to the first step inputs. In the optimum shear reinforcement, using gradient-based methods, the most optimal possible mode is selected based on the existing assumptions. The objective function in this study is a cost function that includes the cost of concrete, formwork and reinforcing steel bars. The steel used in the objective function is the sum of longitudinal and shear bars. The use of a catalog list consisting of all existing patterns of longitudinal bars based on the minimum rules of the regulation in the second stage, leads to a sharp reduction in the volume of calculations and the achievement of the best solution. Three example with varying degrees of complexity, have been selected in order to investigate the optimal design of the longitudinal and shear reinforcement of continuous beam.

The purpose of this study is to understand what two models of SOLO taxonomy and van Hiele theory suggest and find out what relation there is between the category system of the SOLO taxonomy and the thinking level of the van Hiele theory. The van Hiele theory describes in line of ranking level so that it may increase the teaching effects by putting together a class, which takes into consideration the students thoughts. The SOLO taxonomy focused on the response mode of the students rather than the thinking level or the developmental stage of them to pursuit the method that can describe the students understanding in depth quality-wise. Although the SOLO taxonomy and the van Hiele model seem to have different form and character from outside in terms of their goals, a closer examination reveals that the two stances have much in common and that the models are complementary. Although the van Hiele placed more focus on the thoughts, because the conclusion was based on the students responses, the van Hiele theory can be interpreted within the structure identified in the SOLO model. In this study, we have tried to understand how the response structure form the SOLO taxonomy and the thinking level of the van Hiele theory are related, based on the studies of Pegg and Davery1998). If you briefly look at them, there are following corresponding relation between the SOLO taxonomy and the van Hiele theory. a) The relational level(R) in iconic moe is van Hiele level 1. b) The multisturctural level(M$_2$) in the second cycle of concrete-symbolic mode is van Hiel level 2. c) The relation level(R$_2$) in the second cycle of concrete-symbolic mode is van Hiele level 3. d) The unistructural level(U$_2$) in the second cycle of formal mode is van Hiele level 4. e) The postformal mode is van Hiele levle 5. Though it would be difficult to conclude that these correspondences were perfectly done, if you look at their relation, you can see that the learning process of the students were not carried out uniformly. Therefore, by studying the students response structure, using the SOLO taxonomy, and identifying the learning cycle and understand the geometrical concept more in depth.

Purpose: The purpose of study was to describe and evaluate the educational status regarding clinical practicum for child health nursing to facilitate student's clinical compliance for the bachelor's degree in Korea. Methods: The study was a descriptive study and included data from 40 institutions among the 53 university nursing programs in Korea(75.5% response rate). Data were collected using mailed semi structured questionnaires and content analysis was done. Results: Findings show that most institutions have common learning objectives for the clinical practicum; neonatal care, high risk infant care, hospitalized child care, and advanced nursing practice. The mode for theoretical credits in child health nursing was 5 to 6 and 3 to 4 credits for clinical practice. The practice settings were prepared to provide diverse experiences, including childcare centers, and community centers with various learning activities. Evaluation for learning outcomes included faculty and instructors. It was pointed out that updating evaluation based on student and faculty feedback is important for a comprehensive practicum evaluation. Conclusions: Findings suggest that there is a -need for a generalized curriculum for clinical practicum and for the expanding role of advanced nursing practice-, a need for diverse clinical settings for practice, and effective guidance and learning activities. It is significantly noted that the attitude and teaching methodologies of clinical instructor's are highly important to effective clinical learning outcomes.

컴퓨터와 인터넷의 발달은 사회 전 분야에 걸쳐 많은 변화를 가져왔다. 교육 시장도 이에 적극적으로 부응하여 원격교육, 사이버교육, 가상강의, e-Learning 등의 이름으로 제안되어지며 다양한 서비스를 제공하고 있다. 이를 위한 시스템들이 다양하게 제공되면서 컴퓨터를 이용하여 이루어지는 교육과 평가가 활발히 이루어지고 있다. 그러나 많은 시스템들이 제한적 기능을 제공하고 있는 것이 사실이다. 이에 본 논문에서는 학습자들의 교육 이해 수준 정도를 실시간으로 피드백(Feedback)함으로써 교수자가 맞춤식교육을 진행할 수 있는 CBT(Computer Based Training/Test)방식의 쌍방향 자율모드 기반 교육 환경을 제공하는 RTE(Real Training Environment) 시스템을 제안한다. 이 시스템을 활용하여 학습자의 능력에 맞는 맞춤식 교육 환경을 제공하고 학습자들의 학습동기를 극대화시킬 수 있을 것으로 생각된다.

본 연구는 Chauvat의 그래프 사용 모드에 근거하여 고등학교 1학년 학생의 이차함수 문제해결에서 나타나는 그래프 표상의 사용 모드를 분석하고자 한다. 이 분석으로부터 Bannister (2014)의 표상의 유연성을 통해 연구 참여 학생들의 이차함수 이해 정도를 조사하였다. 그 결과 고등학교 1학년 학생들이 주로 사용하는 그래프 표상 모드는 계산 도표학적 모드이며, 조작적 모드를 사용할 경우에는 오류를 발생하는 것을 알 수 있었다. 그리고 함수의 이해를 대상과 과정 관점에서 표상의 사용으로 분류한 Bannister(2014)의 유연성의 분류에서는 과정 관점으로 함수를 이해하고 두 표상 사이에 조작이 일어나지 않는 경직된 형태를 보이는 것으로 나타났다. 이러한 결과를 바탕으로 교실에서 학생들을 위한 그래프 표상 사용에 대한 교육 및 다양한 관점으로 함수를 이해할 수 있는 교수 -학습 방법에 대한 연구가 필요할 것으로 보인다.
