What is a discrepant event in science?
What is a discrepant event in science?
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.
Which of the following 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.
Why are discrepant events a good way for students to think scientifically?
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 happens after demonstrating a discrepant event?
After demonstrating the discrepant event, let your students experiment with the materials to investigate any variable that occurs to them. Ask them to note what questions occur to them, and which variables they investigated.
What is predict observe explain?
In Predict-Observe –Explain strategy students are required to predict the outcome of an event or experiment. The experiment is then performed and observations made by students are probed. When predictions and observations are inconsistent with each other the students’ explanations are explored.
Is discrepant a word?
(usually of two or more objects, accounts, findings etc.) differing; disagreeing; inconsistent: discrepant accounts.
What is accomplished by using discrepant events in elementary science?
When presented with a discrepant event, students are forced to reconsider their preconceptions and beliefs in light of the new evidence. Doing so creates cognitive conflict and can lead to conceptual change and learning.
Can we use dual coding to teach science?
Dual coding works and, when used correctly, can give students a learning advantage. According to learning scientist Dr. Megan Sumeracki, “When used well, combining those can provide two ways of remembering the information… We tend to learn best when we combine multiple modalities together.”
Can we use games to teach science?
Both educators believe that gaming can hit the target in student-centered learning better in several ways than many other instructional techniques for science, by offering a better way to simulate real life, promoting persistence and prompting authentic collaboration. Gaming eliminates constraints.
What is a Poe in teaching?
Prediction-Observation-Explanation (POE) is a constructivist teaching strategy developed by White and Gunstone (1992). The POE strategy is often used in science teaching. First, this strategy helps to uncover individual students’ predictions, and their reasons for making these about a specific event.
What is Poe E?
The Use of Predict-Observe-Explain-Explore (POEE) as a New Teaching Strategy in General Chemistry-Laboratory.
What is discrepant mean?
: being at variance : disagreeing widely discrepant conclusions.
How are discrepant events used in science demonstrations?
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 audience and engage visual learners, particularly young children.
What can I use discrepant events for?
Each of these courses will ask teachers to use Discrepant Events for different purposes Steve Spangler Science videos and activities. Educational science toys, STEM kits, teacher workshop materials, classroom sets, easy science fair projects, slime & amazing experiments by Steve Spangler.
Which is the magic bottle discrepant event in science?
