Using density as a model, this lesson plan has students determine why some soda cans float and others sink. I think students will really enjoy this activity because it directly relates to something about which they know (sinking and floating). It also provides measurable outcomes so the teacher can evaluate the learning that has taken place.
Here is a lesson plan that can be used to teach students to use deductive thinking to evaluate evidence and draw conclusions. I really like the interactive aspect of this activity and love how students need to sift through piles of evidence in order to eliminate fact from fiction. I think this activity would be a great way to develop effective reasoning skills in kids.
Being able to argue effectively is an essential skill in effective reasoning. This video describes how to create a strong argument to defend one's claims. I think this skill is very important to teach students, especially in science class.
Being able to use inductive and deductive reasoning are important factors in the process of effective reasoning. I like how this video outlines the process of inductive reasoning and ties it to argumentations. While the jargon in this video is a bit complex, I think it is a great place to start.
Being able to argue and defend one's conclusions is a key element in the development of effective reasoning skills. The Great Courses series has produced this series of lessons on argumentation. It can be downloaded or purchased on CD. Since argumentation is such an essential part of the effective reasoning, I think viewing this series would be a wonderful way to be introduced to the ideas.
Here is another book chapter that delves deeply into the development of scientific reasoning skills in students. It is part of the book "Current Topics in Children's Learning and Cognition." It is a wonderful, in-depth analysis of how scientific reasoning skills develop. I think this would be a great resource for those interested in how students change their ways of thinking as they develop.
The Sourcebook for Teaching Science has an entire chapter devoted to the development of scientific reasoning skills. This webpage provides links to additional information about the differences between inductive and deductive reasoning, lateral thinking, and Bloom's taxonomy. It is a wonderful resource.
This is a nice, short article that focuses specifically on the use of reasoning skills in the math classroom. It does a good job of presenting various ideas behind the use of logical reasoning and provides some examples of how it can be done. It also discusses how to create a reasoning and sense-making culture in the classroom.
I really like your collection piece on inductive vs deductive reasoning skills. After my students take their EOC, I am planning on doing a forensic chemistry/Sherlock Holmes unit and this goes great with my reasoning for doing that :)
