Independent Project Adrienne Hill EDUS 516 Holy Family University Dr. Parmigiani March 23, 2011 Bogiages, Christopher A., Lotter, Christine (2011). Modeling Natural Selection. The Science Teacher, 78(2), 34-40 This article is written directly for teachers in response to national calls for more inquiry-based learning in the classroom. The thought being that with inquiry-based learning, students not only learn the science content material, but also how to think like scientists. It also fosters excitement and enrichment in the learning process. In summary, this article is a step-by-step guide for educators on how to use model based inquiry and wikis to teach a unit on natural selection. The author defines model based inquiry (MBI) as a pedagogical strategy that engages student’s in modeling using four core conversations: 1) organizing what we know and what we don’t know, 2) generating models, 3) seeking evidence, and 4) constructing arguments. The author divides the unit by day and gives specific strategies and activities to be completed each day with the end goal of completing a wiki in a collaborative effort with their peers. It begins with organizing what we know and what we do not know, to first of all confront students’ misconceptions about natural selection. The second day is spent reviewing and discussing what scientific models and then allowing the students to create their own concept maps based on the What We Know chart from the day before. The third day is spent seeking evidence. The students will be allowed to go online to research and collect evidence on examples of natural selection. They will then modify their models based on what they have learned. On day 4, the pairs of students will construct an argument the links the evidence they found to their original claim or assertion on their concept maps, with given parameters. Day 5 will be spend collaborating with student’s who addressed the same questions grouping together to create a wiki page. This wiki page will contain their combined claims, models and arguments. Students will then use a questionnaire to critique all of the class wikis. After they’ve finished their critiques, the original pairs will have the opportunity to revise their original concept map of how evolution works. This entire article is completely significant to me as a teacher of Biology. It is quite easy to see how the unit would be not only valuable to any science educator, but to the students as well. You could easily replace the topic with any other topic with the same activities and have success. The article stated that students post-assessment testing showed a significant average difference from their pre-assessment data. The authors’ references date from 1989 to 2010. It’s important to note that not all of the references were related to technology, where they would need to be the most current. Many of the references were related to the content area and to education in general. The article was very thorough, providing illustrations to depict charts and examples of the different tools the students would use in this model based inquiry. The article is a valuable tool that any educator could use directly in their classroom. Class Activity relating to the Independent project article: In class, the students would be given a true/false worksheet to allow them to think about Natural Selection and Evolution (attached). After 5 minutes, I would go over the answers to allow everyone to see if they were correct in their assumptions or not. Then I would direct the class to the Khan Academy website to watch a short video presentation titled “Introduction to Evolution and Natural Selection” at this web address: http://www.khanacademy.org/video/introduction-to-evolution-and-naturalselection?playlist=Biology Evolution Study Questions True/False Questions: Answer the following questions True (T) or False (F). 1. _____ Evolution is a scientifically valid theory 2. _____ Organisms existing today are the result of evolutionary processes that have occurred over millions of years. 3. _____ The theory of evolution is based on speculation and not valid scientific observation and testing. 4. _____ Modern humans are the product of evolutionary processes which have occurred over millions of years. 5. _____ There is a considerable body of data which supports evolutionary theory. 6. _____ Most scientists accept evolutionary theory to be a scientifically valid theory. 7. _____ The theory of evolution is capable of being scientifically tested. 8. _____ The theory of evolution cannot be correct since it disagrees with the Biblical account of creation. 9. _____ With few exceptions organisms on earth came into existence at about the same time. 10. _____ The age of the earth is less than 20,000 years. 11. _____ The theory of evolution brings meaning to the diverse characteristics and behaviors observed in living things. 12. _____ Evolutionary theory generates testable predictions with respect to the characteristics of life. 13. _____ Organisms exist today in essentially the same form in which they always have. 14. _____ Evolution is not a scientifically valid theory. 15. _____ Much of the scientific community doubts if evolution occurs. 16. _____ Current evolutionary theory is the result of sound scientific research and methodology. 17. _____ Evolutionary theory is supported by factual, historical, and laboratory data. 18. _____ Humans exist today in the same form in which they always have. 19. _____ The age of the earth is approximately 4-5 billion years. 20. _____ The available evidence is ambiguous as to whether evolution actually occurs.
