Abstract

Almost from the beginning, computer science was hampered by the perception that computer science exclusively focused on programming. This results in computational-related learning being very limited and minimally taught to students. The widespread use of ICT tools in indirect learning has changed the way students interact with content. Conventionally, content is delivered orally to students, who at the same time rely more on approaches that tend to be teacher-centered. This paper presents a slightly different approach, while keeping the teacher at the center of control of classroom activities but students are given the opportunity to explore the content to be learned by: role playing (CS-Unplugged) and conducting a series of experiments (Rapsberry Pi). This learning activity aims to provide students with a foundation of knowledge about how computers work. One of its activities is to provide opportunities for students to do simulations and experimentations about how the computer works through CS Unplugged collaboration and the Role Playing method. The basic knowledge formed from the simulation was then used as the basis for assembling a simple computer using Raspberry Pi. An important point that can be taken from this simulation activity is that the computer does not understand what the computer is doing. The computer only follows the instructions given by computer users. Based on the results of observations and interviews conducted, the utilization of CS Unplugged provides a learning experience that builds on the initial concept of how computers work. This is shown by an increase in students motivation and enthusiasm in learning how the computer works. This experience is what then makes it easy for students to do various computer assembly experiments using Raspberry Pi.
