In this study, we applied a web-based education system to the teaching-demonstrations of the pre-service teachers and identified the usefulness of the system as a method supporting constructive education for pre-service teachers. The pre-service teachers performed the web-based activities for the teaching-demonstrations, and we interviewed them after the teaching-demonstrations. On the basis of the results, we found three situations showing the usefulness of the web-based education system. First, the pre-service teachers examined the materials on the constructive teaching-learning theories and constructed the related theoretical knowledge. At this point the web-based discussion board supported the environment where they thought deeply and investigated the theories carefully. Second, they experienced interaction with others and the academic adviser in the processes of preparing the teaching-demonstrations. This interaction was supported by web-based discussion board, and they were able to form the practical knowledge related to the planning and building constructive teaching. Third, they reflected on their own teaching after the teaching-demonstrations. At this point, the web-based discussion board was able to facilitate the interaction for the reflective thinking processes. In this study, we identified that the web-based education system could provide an effective environment where the pre-service teachers could learn constructive teaching-learning methods.

This study examined the effect of simulated instruction activities based on a constructivist teaching approach on epistemological belief, science teaching efficacy belief, and teaching motivation. The RTOP (Reformed Teaching Observation Protocol) played a role to guide preservice biology teachers to obtain insights on current reformed teaching and to further practice teaching based on constructivism. The results indicated that preservice teachers changed their epistemological beliefs toward more sophisticated views, especially for 'simple knowledge'. They also improved their science teaching efficacy beliefs, both personal science teaching efficacy belief (PSTEB) and science teaching outcome expectancy (STOE). In addition, these perservice teachers decreased their scores of extrinsic teaching motivation. The Pearson correlation represented the negative relationship between personal science teaching efficacy belief (PSTEB) and extrinsic teaching motivation. After intervention, the preservice teachers mentioned inquiry, active participation and discussion as ideal science teaching methods and qualifications for science teachers.

The significant role of joint attention in the development of children with autism spectrum disorder (ASD) has highlighted the importance of early intervention. With the emphasis on the effective cueing and reinforcer for orienting to social stimuli in improving responding to joint attention (RJA) of children with ASD, the use of musical cue was hypothesized. This study aimed to examine the occurrence of RJA behaviors depending on the attentional cue, which differed in the level of information and type of auditory modality. Nine children with ASD participated in this study. The use of eight different joint attention cues were analyzed in terms of the frequency and accuracy of RJA behaviors elicited. The results of the study showed that RJA behaviors occurred more frequently with musical cues than with verbal cues and the mean accuracy rate of RJA was higher with musical cues (p = .047). Musically delivered eliciting and directing cues accompanied with pointing elicited the highest attentional shift and RJA accuracy. The significant increases in RJA with the use of musical cues indicated that incorporating musical elements into an attentional cue may provide more accurate cue information, enough to improve RJA behaviors of children with autism.

그 동안 웹 프로그램 언어인 HTML에 대한 교수-학습 방안과 온라인 학습에 대한 연구들이 이루어져 왔지만 단순 태그 기능 학습에 그쳐 고급사고력을 높이는 프로그래밍학습의 목표를 달성하기는 부족하였다. 본 논문에서는 학습자의 창의력과 문제해결력을 높여주기 위한 HTML 교수-학습 지원 시스템을 설계하였다. HTML 교수-학습 지원시스템은 구성주의 교육 방법인 문제중심학습(Problem-Based Learning)을 이론적 토대의 하여 설계되었으며 나선형 교육과정의 원리에 따라 이원화된 학습요소들에 의해 학습의 위계를 실정하였다. 이 교수-학습지원시스템에서 HTML 학습에 대한 평가는 구성주의 원리에 입각하여 다양한 방식을 통해 지속적으로 이루어지도록 하였다. 또한 교수-학습에 활용되는 해결 과제는 같은 수준, 같은 영역의 문제은행을 축적하여 교수자가 자유롭게 상황에 맞게 선택하여 활용하도록 하였으며, 학습자의 학습 곁과를 통계자료와 도표를 통해 한눈에 살펴보고 적절한 피드백을 주도록 설계하였다. 이와 같은 원리를 토대로 한 교수-학습지원시스템 설계를 통해 학습자가 보다 많은 프로그래밍 경험을 축적하여 창의적이고 자기주도적으로 웹 프로그래밍을 할 수 있는 능력을 키워줄 수 있음을 기대하였다.

Maker education rooted on Maker Movement refers to constructivist learning approach in which students as makers participate in producing visible outcomes through self-directed inquiry and creative hands-on activities in a real life context to solve their personal or social problems. The Maker education, therefore, stresses cultivation of 'maker mindset' in the process-oriented learning environments, pursuing evaluation aspects different from those in the existing educational system. In this context, this study aimed to explore an evaluation framework for the Maker education which reflects the Maker mindset: First, a literature review was conducted to search for the evaluation framework of the maker education which consists of the category of 5 ONs (Minds-on, Hands-on, Hearts-on, Social-on, Acts-on) representing intellectual, physical, emotional, interpersonal and practical aspects, respectively; Second, a Delphi survey for content validity was carried out to confirm the adequacy of the 5 ONs category along with sub-elements for each category. Finally, this study presented the evaluation framework for the Maker education, which is expected to be used as feedback rather than a measuring tool for the process and environments of the Maker education.

역동적 평가는 구성주의와 사회문화적 관점이 교육과정에 많은 영향을 주면서 이를 평가에 반영하기 위한 대안으로 등장한 새로운 평가의 방향이다. 전통적인 심리 측정에 대한 비판에서 시작되었으며, 통계적인 자료정리에서 벗어나 아동에 대한 변화가능성을 평가하자는 것이 주목적이다. 결과 지향적인 평가는 미래의 수행에 대한 완전한 예언을 할 수 없지만, 역동적 평가에서 각 개인의 평가는 개인의 특성에 따라 각기 다른 체제 내에서 이루어진다. 역동적 평가의 입장 가운데서도 본 연구에서는 사회문화적 체제 관점에서 실제영역과 발달가능영역에 대한 사회적 상호작용에 대해 관심을 가지고 있다. 이를 위해 개인에 작용하는 생태학적 회로망을 평가의 주요한 배경으로 선택하고 있으며, 사회문화적 관점에서 평가관의 변화를 제시하면서 이에 따른 수학교육적 시사점을 찾아본다.

Lakoff's (2002) 'nation-as-family' metaphor suggests that conservatism and liberalism in the United States are based respectively on two different sets of morality, i.e., "strict father" morality and "nurturant parents" morality. He argues that values associated with respective metaphors and political principles derived from them tend to determine certain political attitudes and policy endorsement. Using the priming technique, this study attempted to examine whether "strict father" and "nurturant parents" morality are indeed what underlie very different positions conservatives and liberals take towards people in need. The results supported the Lakoff's idea and demonstrated that, compared to priming "nurturant parents" morality, priming "strict father" morality actually led people to derogate character of those in need and to attribute more responsibility onto them for their economic predicament. This research leads us to reconsider what constitutes politically conservative and liberal attitudes and emphasizes the malleability of political attitudes.

The aim of this paper is to put forward the significance that Dewey's naturalistic theory of value has today in examining how value arises from experience. This is a necessary discussion as logical-positivists bring about the problem of fact/value dichotomy and further deny the possibility of intellectual discussion on value judgments. In this situation, the task that the discussion on value must be resolved is to go beyond the problem of fact/value dichotomy and to confer objectivity upon value judgments. In the stream of analytic philosophy, the significance of Dewey's theory of value is revealed by how Putnam and Johnson receive it. To overcome the problem of dichotomy, Putnam asserts that they are entangled because the value arises from a criticism through scientific inquiry. Also Johnson proves that Dewey's moral deliberation as valuation is wedded with cognition, feeling, and imagination by the research on cognitive science and shows that Dewey's theory of value is un-relativistic because it is on the basis of shared experience. So, if the absolute value is not given to us, Dewey's theory of value shows us how value is made by open inquiry. It has the significance of proposing the direction that the theory of value orients itself today.
