Simply put a discrepant event is a surprising occurrence one where the result is the opposite of what is expected.
Discrepant events for elementary students. Using Discrepant Events in Elementary Classrooms. The use of discrepant events in science instruction is a well-researched and well-documented teaching strategy. Simply put a discrepant event is a surprising occurrence one where the result is the opposite of what is expected.
The counterintuitive and often paradoxical results prompt the question. What is a Discrepant Event. A discrepant event is a surprising and paradoxical outcome that is not what an observer would normally expect.
A most common example of a discrepant event would be oobleck. Most children who have never seen it before would not expect it to have both properties of a solid and properties of a liquid. Nor would they expect it to roll into a ball and form but immediately.
A Discrepant Event DE is one that causes an unexpected contradiction in students prior knowledge and experience of a scientific event in support of conceptual understanding Wetzel 2008. Students use problem-solving and critical-thinking skills in order to explain the phenomenon. Inquiry-based instruction that uses such strategies as discrepant events has the potential for developing scientifically literate students Beerer Bodzin 2004.
Similarly this discrepant event. Using his inquiry-oriented experiments based on the science of discrepant eventshands-on explorations or demonstrations in which the outcomes are not what students expectteachers can challenge students preconceived ideas and urge them to critically examine empirical evidence draw logical inferences and skeptically review their initial explanations with their peers. Students focus their attention on phase changes and pressure as this discrepant event creates cognitive dissonance.
They explain the result of placing a hot can in cool water using their knowledge of phase changes and air pressure. A Discrepant Event is something you dont expect to happen and you have to ask yourself. WhyMore Science World Resource Videos.
Discrepant event activity that confronts students with their alternative conception. Given an earth and space science lesson plan identify possible alternative conceptions students might bring to the lesson. Develop one or two key questions to create a confrontation and a possible.
A discrepant science event can be as simple as floating two identical cans of soda one regular and one diet and observing that one floats while the other sinks. Discrepant science events Limón 2001 are designed to puzzle students and cause them to wonder why the event occurred as it did. Freeman 2000 defines a discrepant science event as a.

Painting Fireworks Activity from Learning 4 Kids. The present study is aimed at investigating the use of a discrepant event to facilitate preservice elementary teachers conceptual change on Force and Motion concepts.
The main objectives were to 1 investigate conceptual changes in Force and Motion concepts and 2 track students conceptual change and their learning progression of these concepts. The research method used an intervention with a mixed method design. Second-semester students N120 participated in this study.
Discrepant events are occurrences which defy our understanding of the world by presenting unexpected outcomes. These phenomena are often used in science demonstrations to grab the attention of an.
