Light in Science & Society

Introduction

Group Members• Redouane Eddeane• Martijn van Gerwen• Joost van Heijst• Ralph Huijgen• Jurgen Jongmans• Jos van Mil• Ruud de Wit

Erasmus Intensive ProgrammeUniversity of Ioannina, 11 – 21 June, Ioannina, Greece

Lessons

Focus point lesson series: ‘Light’1. Series of 9 lessons for 4th grade pre-university education2. Prepare a half day workshop for in Ioannina with a very diverse

audience3. Participate in curriculum development in Greece

Challenges

Challenges1. Learning objectives: have to be formulated to clarify the expected

level of sophistication2. Prevent overloaded curriculum:

Lessons cover both chemistry and physics concepts, no need to address separately

3. Irrelevant content: one overall context links the different concepts

Artificial Solar Tree

The lessons

Lesson Description1 Sunlight! Source of sustainable enery

2 The Global Carbon Cycle

3 The energy within the light

4 Solar cells

5 Electrolysis

6 Carbon dioxide capture (CO2)

7 Catalysis

8 Fuel cells versus combustion engines

9 (Lab work) Lab work on solar cells and the fuel cell

Type of learning objectives

Scientific LiteracyPitfall: scientific subject structure only for scientists focus is on

scientific literacy

Lessons: connect ‘Light’ to the discussion about (sustainable) energy. The overall context creates:• Increase in scientific literacy • New solution to the energy problem will motivate • Social & environmental component

Teacher regulation

Process oriented teaching style

Shared control strategyStudents: structure and highlightTeacher: activate, monitor, give feedback Gradual transfer: of learning activities from teacher to student

Promote: congruence and constructive friction

Learning objectives

Need for sustainable energy

All energy traces back to the sun

Carbon cycle

Photosynthesis

CO2

Greenhouse effect

Light = energyYearly use of liquid fuels

Photovoltaic cell

Electrochemical cell

Electrolysis

Reaction kinetics

CO2 capturing and storage

Catalysis

Fuel cell

Combustion engine

Environmental problems

Diversity

Context approach: content for intrinsic and extrinsic motivated studentsTypes of assignments: social and scientific assignments‘Genius’ assignments: the smart student can do these assignments Dealing with diversity will be build into the lesson series.

Beta didactical approach

Pro’s of context based lesson series• Strong link between the concepts and real life• Goal is scientific literacy• Address issues like: real life, profession, environment, student’s life

Cognitivism ConstructivismLesson series

Although the context approach is constructivism, we’ll build the lesson series between cognitivism and constructivism.

Beta didactical ingredientsInformation gathering

IT• Java applets

demonstration, home study to prepare for school• Simulations

understanding cause –effect• Examples

• Carbon cycle• Electrolysis

Lab work (minds-on)• Give meaning to new theory, adjust conceptions• Develop scientific skills

Artificial Solar Tree
