막구조는 전술한 바와 같이 오랜 역사를 통해서 발전을 거듭해 오면서, 이 시대의 필요성에 따라서 나타나는 대공간을 구성하는데 커다란 역할을 하고 있음을, 세계 각국의 현황을 봄으로서 우리들은 이해할 수 있다. 그러나 막구조의 인식부족과 아울러 금후에도 많은 문제점을 안고 있으며 또한 강력한 장력을 갖는 막재료의 출현으로 무한한 가능성도 배제할 수 없는 흥미로운 건축 구조분야이기도 하다. 본 고에서는 금후의 과제를 다음과 같이 몇개의 분야별로 즉, 막구조의 보급 및 정착, 막재료의 장래 및 막구조의 새로운 가능성 등에 대한 과제에 대해 기술하고자 한다.

The purpose of this study is to analyze mathematical tasks of Korea and the USA textbooks focused on conditions for parallelograms. In this study, structures of task, types of proof and reasoning, and levels of cognitive demand are investigated. The conclusion is as follows: First, with respect to structures of task, structures presented in the USA textbooks are more diverse. Second, with respect to types of proof and reasoning, Korea and the USA prefer IC task and DA task. And task types presented in the USA textbooks are more diverse. Third, with respect to levels of cognitive demand, in both Korea and the USA textbooks, PNC task and PWC task account most. And compared to the USA, Korea prefer algorithms. In addition, we find out implications for reconstruction of Korea textbook. It is as follows: First, with respect to structures of task and types of proof and reasoning, the diversity of composition needs to be raised. Second, with respect to levels of cognitive demand, the concentration in PNC task needs to be declined. And levels of cognitive demand on types of tasks need to be reconsidered. Third, with respect to tasks' topic and material, internal and external connectivities of mathematics need to be strengthened.

This article presents new perspectives for classification of students' mathematical errors on the basis of experiential structuralism. Experiential structuralism's mechanism gives us new insights on mathematical errors. The hard core of mechanism is consist of 6 autonomous capacity spheres that are responsible for the representation and processing of different reality domains. There are specific forces that are responsible for this organization of mind. There are expressed in terms of a set of five organizational principles. Classification of mathematical errors is ascribed by the theory to the interaction between the 6 autonomous capacity spheres. Different types of classification require different autonomous capacity spheres. We can classify mathematical errors in the domain of linear function problem solving comparing cognitive psychological mechanism of experiential structuralism.

The purpose of this study was to examine the structural relationship among task value, self-efficacy, classroom goal structure, and academic emotions(enjoyment, fear, boredom) for promoting self-regulated learning in e-learning course. The results showed that task value, self-efficacy, class goal structure influenced academic emotions and self-regulated learning, and enjoyment had mediation effects among exogenous variables and self-regulated learning. The findings offer implications of facilitating self-regulated learning while considering academic emotions.

This study was conducted to explore the effects of students' problem solving ability according to the level of structuring of curriculum tasks in PBL activities. The study was conducted on 60 college students in curriculum classes. Problem solving ability was measured at the beginning of the semester. And after the midterm exam, PBL activities were conducted. 30 experimental groups performed unstructured tasks. 30 comparison groups performed semi-structured problems. After the task was completed, problem solving ability was measured at the end of the semester. Collected data were analyzed using ANCOVA. As a result, it was verified that the experimental group had a statistically significant improvement in information collection, evaluation, and feedback level than the comparative group.
