An educator may utilize various pedagogies such as hands-on practice, practicum, and project-based learning to enhance a student's competency. Among various pedagogies, project-based learning is one of the well-known pedagogies that may provide similar on-the-job experience. In general, an educator may divide the students into small groups and assign tasks to check students' cooperation skills and achievements during project-based learning. However, an educator may experience difficulties operating project-based learning due to the COVID-19 pandemic. Most of the team activities are done in non-face-to-face meetings, and as a consequence, the educator may not find an underachieving team easily and cannot intervene appropriately. This study introduces a rigorous analysis method to evaluate team activities to analyze individual students' participation and contributions. First, this study develops evaluation rubrics by conducting questionnaires to professors and students to find an appropriate weight value for the evaluation scale. Then, this research introduces an analysis environment to evaluate students automatically. The analysis environment collects dialog data from social network services and measures interactions among students in a team. After measuring interactions, the environment generates a report to visualize the team activities. We applied the proposed method and environment to the capstone design course to show the effectiveness of the method and environment. Based on the case study, the environment showed that the analysis method could easily indicate the teams' activities and check the level of participation.

In this study, modeling pedagogies were employed to re-design and teach the unit of Seasonal Changes in the $6^{th}$ grade science curriculum. The effects of the modeling-based program were investigated in both the conceptual and affective domains using an approach of mixing quantitative and qualitative techniques. The result showed that the students in the modeling-based science inquiry classroom gained a higher mean score in a conceptual achievement test than their counterparts in a traditional science classroom. The number of the conceptual resources activated to explain the causes of the seasons, as well as the types of student explanations developed through the combination of the resources activated, were greater in the modeling-based classroom. The modeling-based science inquiry was also effective in improving student attitudes toward science lessons. It was revealed, however, that the students experienced both positive and negative epistemic feelings during the modeling-based science inquiry. Implications of these findings for science education and relevant research were suggested and discussed.

연구의 목적은 예비 초등 교사들이 여러 가지 전기회로를 설명하기 위한 모델을 개발하고 선택하는 과정에서 동원하는 모델 평가 기준들을 탐색하는 것이었다. 한 교육대학교에서 과학교육 강좌를 수강하는 30명의 3학년 학생들이 연구에 참여하였다. 이들을 위한 수업은 표현적, 실험적, 평가적 모델링을 포함하는 순환적 계열에 따라 조직되었다. 예비 교사들에게 다섯 개의 전기회로를 차례로 제공하고, 그것을 설명할 수 있는 모델을 개발하고 동료들 간의 토론을 통해 점차 모델을 개선해 가도록 하였다. 예비 교사들의 모델링 활동을 모두 녹음 또는 녹화하였고, 모델 평가 기준의 분석틀을 이용하여 녹음 또는 녹화된 것과 전사본을 분석하였다. 그 결과 모델을 개발 개선하는 상황과 모델을 선택하는 상황에 동원되는 모델 평가 기준의 유형과 빈도에 차이가 있음을 알 수 있었다. 즉, 경험적 기준과 이론적 기준이 두 상황에서 모두 주된 평가 준거의 역할을 하였지만, 예비 교사들이 여러 가지 대안적인 모델들 중 하나를 선택하는 상황에서 좀 더 다양한 평가 기준들이 사용되었다. 본 연구가 과학 교육과 과학 교육 연구에 시사하는 점들을 제안하였다.

In education, innovative ways of teaching and learning are always under development and keep being proposed with advanced concepts since the ancient times. Student-centered learning, problem-based learning and cooperative learning have been three major trends under development in secondary education research and practice more than a decade or so. Combined with advanced information and communication technologies, these trends will greatly transform the way we teach and learn in classroom environment and may change the classroom environment itself, into a more interactive and self-centered coaching type environment. In this study, a smart environment that utilizes advanced information technology devices and network is conceptualized, accommodating requirements contained and proposed in the recent trendy pedagogies. Pedagogical cases discussed in these trends are analyzed in detail, producing requirements for such a learning and coaching environment. These requirements are modeled using unified modeling language, leading to a proposal of a basic architecture for an information system supporting this environment.

As a consequence of sudden outbreak of COVID-19 pandemic worldwide, educational institutes around the globe are forced to switch from traditional learning systems to e-learning systems. This has led to a variety of technology-driven pedagogies in e-teaching as well as e-learning. In order to take the best advantage, an appropriate understanding of the cognitive capability is of prime importance. This paper presents an intelligent cognitive maturity recognition system for confidence-based e-learning. We gather the data from actual test environment by involving a number of students and academicians to act as experts. Then a Genetic Programming based simulation and modeling is applied to generate a generalized classifier in the form of a mathematical expression. The simulation is derived towards an optimal space by carefully designed fitness function and assigning a range to each of the class labels. Experimental results validate that the proposed method yields comparative and superior results which makes it feasible to be used in real world scenarios.
