CHEM-342 Jigsaw Group Assignment Construct a Concept Map that summarizes the significance of the articles you are studying and can be useful to the rest of the class. What does it mean when you say, I understand?.... Does it mean the same thing to you that it does to another student or to the professor?..… How can you demonstrate you understanding to others? Concept Mapping • What is a concept map? • What are the features of a concept map? • How do you construct a concept map? What is a Concept Map? A Concept Map Includes: laptop Linking Phrase Nodes (terms or concepts) needs a Linking lines (usually with a unidirectional arrow) charge Linking Phrase Linking phrases Propositions Linking Phrase Linking Phrase Linking Phrase Linking Phrase Short Assignment Arrange the following three terms and connect them with arrows and linking phrases Bacteria Pneumonia Antibiotics A Mini Concept Map Caused by Pneumonia Bacteria Antibiotics Variations on a Theme Pneumonia Caused by Antibiotics Bacteria Bacteria Antibiotics Can cause Pneumonia Can cause Bacteria By reversing the arrows, changing the linking words, and adding color, the focus and emphasis changes.

Brainstorming Stage Organizing Stage • Spread concepts on a table or blackboard so that all can be read easily. • Create groups and sub-groups of related items. Try to group items to emphasize hierarchies. • Identify terms that represent higher categories and add them. • Feel free to rearrange items and introduce new items omitted initially. • Some concepts will fall into multiple groupings. This will become important in the linking stage. Organizing Stage Layout Stage • Arrange terms so that they represent your collective understanding of the interrelationships and connections among groupings. • Use a consistent hierarchy in which the most important concepts are in the center or at the top. • Within sub-grouping, place closely related items near to each other. • Think in terms of connecting the items in a simple sentence that shows the relationship between them. • Feel free to rearrange things at any time during this phase. • Do not expect your layout to be like that of other groups. Layout Stage Linking Phase • Use lines with arrows to connect and show the relationship between connected items. • Write a word or short phrase by each arrow to specify the relationship. • Many arrows can originate or terminate on particularly important concepts. Revising Stage • Carefully examine the draft concept map. • Rearrange sections to emphasize organization and appearance. • Remove or combine items to simplify. • Consider adding color or different fonts. • Discuss any aspects where opinions differ Finalizing the Concept Map • After your group has agreed on an arrangement of items that coveys your understanding, convert the concept map into a permanent form that others can view and discuss. • Be creative in a constructive way through the use of colors, fonts, shapes.

Are the concepts and relationships correct? Are important concepts missing? Are misconceptions apparent? Organization. Is the concept map laid out in a way that higher order relationships are apparent and easy to follow? Does it have a title? Appearance. Is the assignment done with care showing attention to details such as spelling and penmanship? Is it neat and orderly or is it chaotic and messy? Creativity. Are there unusual elements that aid communication or stimulate interest without being distracting?
