The purpose of the article is to address a new instructional approach to a complex engineering course. We design a novel instructional method that combines mobile technology, simulation program, collaborative teamwork, problem-solving process, and a variety of evaluation techniques. We suggested five instructional principles that might be required to change the fundamental educational process by which learning is done. The proposed instructional method is expected to aspire for new perspectives on complex learning environment. Nevertheless we solely began by the research on the development of students' complex problem-solving performance in a complex engineering course, the new instructional method in the article can promote the adoption of new instructional methods and strategies across different knowledge domains. In addition, the instructional method can provide a valuable bridge to acquisition and transfer of problem solving, motivation, and meaning learning.

이 연구에서는 이미 해결한 단일개념으로만 구성된 복합개념상황에서 학생들의 문제해결력과 정신용량의 관계를 알아보았다. 과학적 개념이나 원리 하나만 알면 풀 수 있는 문제를 단일개념상황으로 정의하였고 단일개념상황을 2개 이상 결합하여 만든 문제를 복합개념상황으로 정의하였다. 청주시 소재 일반계 고등학교 2학년 학생 152명을 대상으로 정신용량에는 유의미한 차이가 나타나지 않았다. 그러나 이미 해결한 단일개념상황들의 결합으로 만들어 전 복합개념상황의 문제해결에 있어서는 정신용량이 작은 집단에서만 실패한 학생들이 나타났으며 문제해결에 실패한 학생들의 정신용량이 문제해결에 성공한 학생들의 정신용량보다 낮았다. 이러한 연구 결과 단일개념상황은 해결할 수 있으면서 이와 관련된 복합개념상황의 해결에 실패한 이유의 하나를 문제해결자의 정신용량이 작기 때문이라고 볼 수 있다.

The core issue of ethical problem solving in engineering is to understand what exactly happened and to define its nature. Problems often arise mostly in morally complex situations. Traditional philosophical theories usually focus on extreme conflicts of interest and suggest moral theory-centered problem solving methods. However, these methods are not only difficult to specifically apply to real situations, but also are likely to fail to deal with actual moral issues in engineering fields. This study aims to develop more desirable ethical problem solving methods, based on STS (Science and Technology Studies) and engineering ethics combined. First, we have examined the engineering ethics with implications of an STS perspective, then have analyzed traditional ethical problem solving methods in a critical point of view. This study will suggest a new ethical problem solving method named Matrix Guide, based upon those analyses. Specifically, this study classifies four stages of problem definition, analysis, solving, and feedback. Here, we focus on how to combine technological and non-technological factors in each stage, when we are facing morally complex situations in engineering sectors.

This paper describe an approximation method for solving the minimum makespan problem of job shop scheduling with fuzzy processing time. We consider the multi-part production scheduling problem in a job shop scheduling. The job shop scheduling problem is a complex system and a NP-hard problem. The problem is more complex if the processing time is imprecision. The Fuzzy set theory can be useful in modeling and solving scheduling problems with uncertain processing times. Lee-Li fuzzy number comparison method will be used to compare processing times that evaluated under fuzziness. This study propose heuristic algorithm solving the job shop scheduling problem under fuzzy environment. In This study the proposed algorithm is designed to treat opinions of experts, also can be used to solve a job shop environment under the existence of alternate operations. On the basis of the proposed method, an example is presented.

본 논문에서는 정보영재의 창의적 문제해결력 향상을 위한 STEAM 기반 쓰기 활용 전략을 제안한다. 창의적 문제해결(creative problem solving)을 위해서는 다양한 요소의 복합적이며 역동적인 상호작용이 필요하며, 이러한 상호작용을 유도하고 실세계의 복잡한 문제를 해결할 수 있는 능력을 함양하기 위해서는 융합교육을 통해 다양한 학문을 아우르는 학습 경험을 제공해야 한다. 또한, 다양한 교과에서 이미 교육적 효과가 검증된 쓰기는 비판적 사고를 유도하고 문제해결의 시작이라 할 수 있는 문제인식을 도와 창의적 문제해결에 긍정적 영향을 줄 뿐만 아니라, 문제 해결과정과의 유사성을 바탕으로 문제해결력 향상을 위한 효과적인 도구로 쓰일 수 있다. 학습자들은 일상생활에서 흔히 사용하는 자판기, 휴대전화 같은 첨단기술 제품을 사용한 경험을 쓰고 분석하는 과정을 통해 알고리즘을 찾고 실생활에 쓰이는 여러 학문의 원리를 자연스럽게 학습하면서 다양한 사고의 융합과 상호작용을 경험하고 창의적 문제해결력을 함양할 수 있다.

This paper focuses on how an integrated or systemic approach is needed to both investigate and connect different kinds of interdisciplinary inquiry and knowledge within and beyond universities to encourage more productive collaboration with the other three ‘macro stakeholders’ - government, business, and the wider community. In this way universities can and should provide a greater leadership role in sustainability, innovation and policy studies. Such a framework is needed to also help to change the view of many that academics should just play a supporting role of providing specialised technical expertise only to the other macro stakeholders. The interdisciplinary and collaborative framework developed here is applied to the on-going water crisis in Malaysia - an exemplary complex problem-solving basis for seeking sustainable policy solutions to diverse challenges. As further discussed, this was applied also in practice to a multi-stakeholder seminar on addressing the difficult policy challenges of the Malaysian water industry and sector.

In the previous study, six factors which could disturb students' problem solving in an everyday context were identified and discussed. In this study, teaching materials to help students overcome those disturbing factors for successful problem solving in an everyday context were developed and applied to twenty-nine grade 10 students, and the effects of teaching materials were analyzed. According to the analysis of the correlation between the performance in everyday context problem solving and the benefit from the teaching materials, it was found that students who received the help from the teaching materials showed better performance with statistical significance. And students noted that teaching materials were helpful for them to solve the physics problems. Analyzing the overall performance of students in solving the everyday context problem, students in the experimental group showed better performance than the control group and this performance difference was larger among low-score students in school science testing. However, these differences were not statistically significant because the sample size was small. And, based on the analysis of interviews with students, it was also found that some students who showed low performance might not receive help from the teaching materials because the materials were too complex to be read easily, or because the basic concepts needed to solve the problem were not understood. Therefore, the results obtained from the interviews will be used to design more effective teaching for problem solving in an everyday context.

초등수학 문제해결에서 사용되고 있는 문장제를 동일 수학적 내용이나 구조를 취하되 단문중심 유형과 복문중심 유형의 두 문장제로 재구성하여 이를 한 조합으로 묶은 후, 이에 대한 학생의 문제해결 활동에서 문장제 유형에 따라 보여주는 인지 정의적 반응의 비교분석을 통해서 초등학교 문제해결 지도에 시사하는 바를 알아보았다. 수학교과에서 다루는 문장제를 구성하는 문장은 그 자체가 학습 내용이나 대상이 되는 것이 아니라, 수학 학습이나 지도를 위한 도구로서 사용되는 것이기 때문에 전통적으로 '간결한 표현'이라는 문장의 경제성 추구보다는 '분명한 정보의 간편한 전달'이라는 문장의 편의성에 집중할 필요가 있다고 생각한다. 즉, 초등 학생의 언어적 이해의 단순결함으로 인한 문제해결 수행상의 오류나 부정적 수학 학습태도를 해소시킬 수 있도록 학생의 국어적 평균 수준에 맞추어진 수학적 문장 을 통하여 수학적 정보를 온전하면서도 편리하게 표현과 전달을 꾀하려는 연구와 실천이 중요하다고 생각한다.

In this paper we describe Task-Based Problem Solving Adapters (TPSAs) for modeling a humam solution (through activity-centered analysis) to a software solution (in form of computer-based artifact). TPSAs are derived from the problem solving pattern or consistent problem solving structures/strategies employed by practitioners while designing solutions to complex problems. The adapters developed by us lead toward human-centeredness in their design and underpinning that help us to address the pragmatic task constraints through a range of technologies like neural networks, fuzzy logic, and genetic algorithms. We also outline an example of applying the TPSAs to develop a working system for assisting sales engineers of an electrical manufacturing firm in preparing indent and monitoring the status of orders in the company.
