  • 이 연구에서는 뇌기반 진화적 교육 원리를 도출하기 위하여, 인간 뇌의 구조적 기능적 특징, 개체간과 개체내에서 일어나는 생물학적 진화, 뇌내에서 일어나는 진화적 과정, 과학 자체와 개별 과학자의 과학적 활동에 내재된 진화적 속성에 관한 연구물을 리뷰하였다. 이렇게 하여 도출된 인간 뇌의 주요 특징과 생성-선택-파지를 핵심 요소로 하는 보편 다윈주의 혹은 보편 선택주의를 토대로, 뇌기반 진화적 과학 교수 학습 모형을 개발하였다. 이 모형은 세 가지 요소와 세 가지 단계 및 평가로 이루어진다. 세 가지 요소는 정의적, 행동적, 인지적 요소이고, 각 요소를 구성하는 세 단계는 다양화 $\rightarrow$ 비교 선택 $\rightarrow$ 확장 적용(ABC-DEF; Affective, Behavioral, Cognitive components - Diversifying$\rightarrow$Emulating, Estimating, Evaluating $\rightarrow$ Furthering steps)이다. 이 모형에서 정의적 요소 (A)는 인간 뇌에서 감성을 관장하는 대뇌변연계에 토대를 두고 자연 사물과 현상에 대한 학습자의 흥미 호기심과 관련된다. 행동적 요소(B)는 시각 정보를 처리하는 후두엽, 언어 정보의 이해.생성과 관련된 측두엽, 감각운동 정보를 처리하는 감각운동령을 수반하고 과학적 활동의 직접 해보기와 관련된다. 인지적 요소(C)는 사고, 계획, 판단, 문제해결과 관련된 전두엽합령에 토대를 둔다. 이 모형은 이러한 측면에서 '뇌기반(brain-based)'이다. 이 모형의 세 가지 각 요소를 구성하는 세 단계에서, 다양화 단계(D)는 각 요소에서 다양한 변이체를 생성하는 과정이고, 가치나 유용성에 비추어 비교.선택하는 단계(E)는 변이체들 중 유용하거나 가치 있는 것을 검증하여 선택하는 과정이며, 확장.적용 단계(F)는 선택된 것을 유사한 상황으로 확장하거나 적용하는 단계이다. 이 모형은 이러한 측면에서 '진화적(evolutionary)'이다. ABC 세 요소에 대해, 과학적 활동에서 감성적 요인이 출발점으로 갖는 중요성과 뇌에서 사고 기능과 관련되는 신피질에 비해 감성을 관장하는 대뇌변연계의 우세한 역할을 반영하여 DARWIN (Driving Affective Realm for Whole Intellectual Network) 접근법을 강조한다. 이 모형은 학교 현장에서 다루는 과학 주제와 학생의 특징에 따라 다양한 형태와 수준으로 융통성 있게 실행될 수 있다.

  • India is a developing nation and has come with comprehensive way in modernizing its reducing poverty, economy and rising living standards for an outsized fragment of its residents. The STEM (Science, Technology, Engineering, and Mathematics) education plays an important role in it. STEM is an educational curriculum that emphasis on the subjects of "science, technology, engineering, and mathematics". In traditional education scenario, these subjects are taught independently, but according to the educational philosophy of STEM that teaches these subjects together in project-based lessons. STEM helps the students in his holistic development. Youth unemployment is the biggest concern due to lack of adequate skills. There is a huge skill gap behind jobless engineers and the question arises how we can prepare engineers for a better tomorrow? Now a day's Industry 4.0 is a new fourth industrial revolution which is an intelligent networking of machines and processes for industry through ICT. It is based upon the usage of cyber-physical systems and Internet of Things (IoT). Industrial revolution does not influence only production but also educational system as well. IoT in academics is a new revolution to the Internet technology, which introduced "Smartness" in the entire IT infrastructure. To improve socio-economic status of the India students must equipped with 21st century digital skills and Universities, colleges must provide individual learning kits to their students which can help them in enhancing their productivity and learning outcomes. The major goal of this paper is to present a low cost, effective learning mechanism for STEM implementation using Raspberry Pi 3+ model (Single board computer) and Node Red open source visual programming tool which is developed by IBM for wiring hardware devices together. These tools are broadly used to provide hands on experience on IoT fundamentals during teaching and learning. This paper elaborates the appropriateness and the practicality of these concepts via an example by implementing a user interface (UI) and Dashboard in Node-RED where dashboard palette is used for demonstration with switch, slider, gauge and Raspberry pi palette is used to connect with GPIO pins present on Raspberry pi board. An LED light is connected with a GPIO pin as an output pin. In this experiment, it is shown that the Node-Red dashboard is accessing on Raspberry pi and via Smartphone as well. In the final step results are shown in an elaborate manner. Conversely, inadequate Programming skills in students are the biggest challenge because without good programming skills there would be no pioneers in engineering, robotics and other areas. Coding plays an important role to increase the level of knowledge on a wide scale and to encourage the interest of students in coding. Today Python language which is Open source and most demanding languages in the industry in order to know data science and algorithms, understanding computer science would not be possible without science, technology, engineering and math. In this paper a small experiment is also done with an LED light via writing source code in python. These tiny experiments are really helpful to encourage the students and give play way to learn these advance technologies. The cost estimation is presented in tabular form for per learning kit provided to the students for Hands on experiments. Some Popular In addition, some Open source tools for experimenting with IoT Technology are described. Students can enrich their knowledge by doing lots of experiments with these freely available software's and this low cost hardware in labs or learning kits provided to them.
