• Physical Computing in Computer Science Education

– In Korea, revision of computer science education

curriculum for K-12 students [3][4].

– Physical computing project is a good topic to learn

programming and computer science concept [5].

Introduction


• What is Physical Computing?

Introduction


• Benefits of physical computing education

– Learn with a computer science and engineering knowledge

• through the process of building a computing system consisting of

the physical input and output devices and control program[6].

– Lead to creative learning, through project-based learning

and cooperative learning[7].

• Use innovative new technologies

• Construct of knowledge through making or tinkering process

Introduction


• What is problem?

– Lack of research

– Uncertainty of educational effectiveness

• The Propose of this study

– analyze the educational tool for physical computing

education

– consider the educational environment such as level of

learners and objective and classroom

Introduction


• What is the educational tools?

– Hardware

• Process the input or output data

• function as a microcontroller or microprocessor

• Selection criteria of tools

– now widely used in schools

– Whether standard model

• Selected educational tools

– Pico board, Arduino and Raspberry Pi.

Backgrounds


• Features of the Pico board are as follows[9]:

– single-board microcontroller;

– built-in light sensor, push button, slider, mic sensor,

resistance;

– available from scratch by connecting to a computer without

configuring a separate electronic circuit

Backgrounds


• Features of the Arduino are as follows [10]:

– open-source prototyping platform based single-based

microcontroller

– control digital and analog input or output data

– projects can be made through sensor input, motor control,

data communication and so on

– support multiple languages C, C++, Python, Scratch.

Backgrounds


• Features of the Raspberry Pi are as follows[11]:

– single-board computer and linux and windows operating

systems supported

– very cheap price (approximately $35)

– control digital and analog input or output data

– excellent in a number of data processing and graphics

operations

Backgrounds


• Analysis factor

– Complexity

• the level of learning complexity

• How difficult?

– Readiness

• the number of preparation material

• How many preparation materials do you need?

– Utilization

• the number of projects

• How many project can you create?

Results


Board Name Complexity Readiness Utilization

Pico Board Low Low Low

Arduino Middle Middle High

Raspberry Pi High High High

Results

Table 1. Comparison of Educational Tools

• Learning Complexity

– Pico board only detect a sensing data.

– Arduino control sensing and actuator devices.

– Raspberry pi is a computer.






Results


• Readiness, the number of preparation materials

– Pico board is only required computer and a few electronic

components.

– Arduino requires a computer and additional electronic

components for circuit construction.

– Raspberry Pi is needed peripheral devices because it can be

a computer itself.






Results


• Utilization, the number of projects

– Pico board is only relatively low utilization, but it can be associated with various types of projects from scratch.

– Arduino is more suitable for making the project controlling an external device, such as a sensor or motor.

– Raspberry Pi is more suitable for complex numerical calculations related to the project or produced by the graphic data processing.


• From the level of complexity,

– starting from the sensor board such as Pico board to

Arduino, and then Raspberry Pi.

• From the level of readiness,

– Additional materials are required.

• From the level of utilization,

– According to the physical computing project goals, tools

have to be chosen.
