What is discrepant event in science teaching?
Discrepant events — demonstrations that produce unexpected outcomes — are used in science to capture students’ attention and to confront their beliefs about a “phenomenon by producing an outcome which is contrary to what their previous experiences would lead them to believe is true” (Misiti, 2000, p.
Why is it important for teachers to use discrepant events in the science lessons?
Discrepant events increase scientific understanding and natural sense of curiosity for brain based experiments and demonstrations, film, explanation of a series of events, laboratory tests and a natural event through school trip by providing a deep thinking and discussion of the results (O’Brien, 2011; Weller, 2008).
What are two applications of discrepant events that can be used as part of a larger instructional strategy?
Discrepant events can be used in classrooms:
- to engage students in inquiry.
- as a demonstration followed by discussion to introduce a new topic.
- to engage students in science processes skills.
- as a small group lab activity.
- as a mind-on warm-up to stimulate critical thinking.
- as a take home lab activity.
What does discrepant event mean?
Discrepant events—demonstrations that produce unexpected outcomes—are used in science to capture students’ attention and to confront their beliefs about a “phenomenon by producing an outcome which is contrary to what their previous experiences would lead them to believe is true” (Misiti, 2000, p. 34).
How do you do dual coding?
Dual coding is combining words and visuals such as pictures, diagrams, graphic organizers, and so on. The idea is to provide two different representations of the information, both visual and verbal, to help students understand the information better.
What is an example of dual coding?
Dual-coding theory postulates that both visual and verbal information is used to represent information. Both visual and verbal codes can be used when recalling information. For example, say a person has stored the stimulus concept “dog” as both the word ‘dog’ and as the image of a dog.
Why do you use discrepant events in science?
Discrepant events pique students’ interest and leave them craving the knowledge that you plan to teach them. Students are often left begging you to tell them “how did that happen?” That’s the kind of engagement we need (and want!) in science. It’s a win-win! What is a Discrepant Event?
How are discrepant events used in elementary classrooms?
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.
Why do students dislike taking a science class?
Many discrepant events challenge “common sense” beliefs and can thus engage students who dislike traditional science class. Literacy is also easily integrated as students use the skill of observation to describe the event, form hypotheses, investigate the phenomenon, and discuss their findings with others.
