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
