CSI: Science Professional Development

This professional development session focuses on the significance of discrepant events in science education. Participants will explore how these events challenge students' preconceived notions and promote deeper understanding. The agenda includes discussions on the purpose of discrepant events, engaging activities like “A Watery World” and “The Incredible Journey,” and strategies for assessing student comprehension through concept mapping. Ultimately, this workshop aims to equip educators with tools to inspire critical thinking in their classrooms.

  2. Day One Agenda • The Purpose of Discrepant Events • A Watery World • Investigation 4: The Incredible Journey • The Notion of Idea Pools • Question and Answer Time

  3. The Purpose of Discrepant Events • “Believing is seeing, but seeing is not believing” (Tsai, 2000). • “Conservation of equilibration” (Rowell, 1989) theorizes that humans tend to resist change and some contradictory evidence does not necessarily convince them that they existing conceptions are not satisfactory (Dreyfus, 1990; Duit, 1991; Rowell & Dawson, 1983).

  4. The Purpose of Discrepant Events • Discrepant events are designed to provide novel evidence to challenge human alternative conceptions (Tsai, 2000). • The problem lies in the fact that not all humans accommodate their alternative conceptions to scientific ones through experiencing the discrepant events (Tsai, 2000). • Accommodation occurs when new perceptions cannot fit into one’s existing conceptions (Bodner, 1986).

  5. The Stages of Discrepant Events • First, students are asked to predict what they expect to happen before the demonstration is conducted and offer an explanation as to why they think it should happen that way. • Second, the students observe what happens and are asked to modify their previous explanation. • This assists students in analyzing their thought processes, but can sometimes be difficult to assess.

  6. Assessing Discrepant Events • Concept mapping/conflict mapping • Schematic diagrams that use words to show the relation of one concept to another • Show the mind component as well as the environment component; then allow the students to justify the shift in thinking through scientific reasoning

  7. The Thought for the Day
