50 JAAR HIGH TECH, HUMAN TOUCH

Go-Lab:

a portal for pedagogically embedded online labs

Ton de Jong University of Twente The Netherlands

We need engaging (science and engineering) instruction

What can we do?

• Constructive (inquiry) learning
• Collaborative learning
• Situated learning
• Computer simulations/ games
• Modeling (design) environments
• Shared objects
• Chats, video conferencing
• Simulators, videos

Are virtual labs/simulations effective?

If well designed, guidance included, inquiry- based learning with online labs and simulations shows an advantage over expository instruction

de Jong, T. (2006). Computer simulations - Technological advances in inquiry learning. Science, 312, 532-533.

Example meta-study

• 59 studies included, 128 effect sizes
• Achievement outcomes

– Simulation > No simulation (N = 2947) – Simulation plus > Simulation (N = 3342) – Moderately high effect sizes

d'Angelo, C., Rutstein, D., Harris, C., Bernard, R., Borokhovski, E., & Haertel, G. (2014). Simulations for STEM learning: Systematic review and meta-analysis. Menlo Park, CA: SRI International.

• 59 studies included, 128 effect sizes
• Inquiry skills

– Simulation = No simulation (N = 347) – Simulation plus > Simulation (N = 689) – Moderately high effect size

Are virtual labs/simulations effective?

de Jong, T., Linn, M.C., & Zacharia, Z.C. (2013). Physical and virtual laboratories in science and engineering

• education. Science, 340, 305-308
• Students in online labs gain the same level of

knowledge or a more advanced level of knowledge than students who learn in a real laboratory

Effectiviness of virtual labs compared to wet labs

• The possibility to perform many more

experiments

• The possibility to augment labs
• The possibility to combine labs with online

pedagigical support

And how about remote labs?

• The possibility to perform many more

experiments

• The possibility to augment labs (example Luis

laser)

• The possibility to combine labs with online

pedagogical support

Problems in discovery

• Poor hypotheses
• Ineffective experiments
• Engineering approach
• Mistakes in data interpretation
• No planning and monitoring (floundering)
• etc.

Scaffolds in Go-Lab

• Orientation phase: Concept map
• Conceptualisation phase: Hypothesis/question

scratchpad

• Investigation

– Experiment design tool – Observation tool – Data interpretation tool – Error measurement tool

• Conclusion tool
• Reflection tool

Example Guidance (Scaffold): Hypothesis scratchpad

• Virtual laboratories
• Mimic physical equipment in software
• Remote laboratories
• Physical equipment that can be operated on a distance
• Data sets and their analysis tools
• Data gathered in real experiments
