Teacher’s Meeting for HKDSE Physics SBA:

Experiment Using Arduino Modules

03-November-2018

Project Overview: Flipped Classroom Learning Approach

• Blended learning that reverses traditional learning approaches • Spontaneous • Online • Outside of classroom • Activity-based • Hands-on experience

• Experiments are essential learning process in sciences subjects

Problems Inadequate experiments for students because of the followings:

Typical Solutions

• Ignorance of real-life uncertainty and errors

• Limited number and types of equipment • Time constraint due to tight

teaching schedule • Different learning progress of individuals • Risks of experiments

1. Video or slide demonstrations 2. Computer simulations

Drawbacks: • Highly passive learning

process / No experimental skills examined

AP Sensor App Remote Lab

Our Solution: Flipped Classroom Learning Trio

Arduino-Smartphone Platform

Arduino-Smartphone Platform

Our Solution: Arduino-Smartphone Platform • Arduino

• Extended Sensor • Data logger • Data transmission via Bluetooth / Wi-

Fi • Smartphone App

• User control interface • Data retrieval, display and storage

• 2 Demos • Magnetism • Ideal Gas Law

Arduino-Smartphone Platform: How It Works?

1. Arduino sensors detect surroundings 2. Micro-controller retrieves signal

from sensors 3. Data is sent to smartphone via Bluetooth 4. Smartphone decodes data 5. App interface displays data and

graph on screen

Advantages of Using Smartphones • Widely accessible by students • Portable and no time restrictions • Many built-in sensors with high accuracy available • Expandable sensor types with Bluetooth and Wi-Fi • Fast data processing speed • Multiple data and graph display on single screen

Advantages of Using Arduino • Significantly low cost • Various sensor types available • Highly flexible combinations of sensors • Portable and no time restrictions • Open source

Arduino Board

Benefits • Reduce capital cost for equipment • Reduce time and labor cost for experiment set-up • Flexible place and time for repeated experiments • Hands-on learning experience of individual students • Maximum efficiency with sharing equipment • Foster STEM education in high schools

Short-term Goals • To invite more physics teachers from

secondary schools to participate in the project

• To facilitate classroom teaching and learning with the tools provided

• To testify this teaching approach in classes and modify according to any setbacks

• To evaluate the effectiveness of this approach on boosting student’s spontaneous learning incentive

Long-term Goals

• To evolve into self-sustaining mode of Internet of Things (IoTs)

• To enable teachers and students to devise their own experiments

• To develop a web-based system for sharing of information and online assessment such as IES

Current Progress • 2 experiments developed, 2 under development • Trial run with 7 pilot schools rotating 8-10 sets of equipment • Feedback collections from teachers and students • Bug fixes and improvements upon feedbacks

Experiments 8 sets of experiments (4 in Phase I and 4 in Phase II) will be devised in due course of the project. Phase I: • Gas Law • Magnetism • Environment (PM2.5, UV, pH) • Growth of Plants (Temperature, humidity, O2 and CO2) Phase II: TBC
