Model for Learning - System Concept Maps low tech: high tech Do C-maps help students learn? How well do C-maps reveal students’ thinking? What evidence will we accept? 1 2 Questions o Pr How many of you are familiar with concept maps? How many of you used concept maps for teaching tools and/or assessment tools? If a concept mapping tool was easily accessible on the web, would that influence your decision to use them? i p ty to Kn ow l l ca ed ge Concepts are... -b as ed Lexical 3 4 Knowledge-based Lexical rock: a naturally formed solid that is an aggregate of one or more minerals Your associations with the term “rock”. 5 6 Prototypes Rock: prototype/exemplar Which is the baby?

Reflection & Learning 11 Prior Knowledge New Information 12 Goal: Demonstrate your ability to develop a concept map using low tech and high tech tools. LOW Tech C-Map Context: Wetlands are among the most productive ecosystems in the world, more productive than tropical rainforests. Differences in rates of primary productivity are influenced by moisture and temperature. Importantly, the carbon cycle is key to fluctuations in primary productivity. Since primary productivity is examined and understood at many scales, from the cellular to ecosystem level, it is necessary that you revisit your thinking about major concepts related to the carbon cycle and primary productivity. Goal: explain evolution by natural selection Use C-TOOLS to make a concept map that illustrates both the hierarchy and relationships between and among concepts listed below. You may add up to 3 additional concepts if needed. WORK in PAIRS with Postits. Photosynthesis Respiration Carbohydrates Primary productivity Carbon dioxide Water Oxygen Energy 13 Individual Problem 14 What do different forms of assessment reveal? List the concepts for an exemplary short answer Now make a concept map using those concepts Compare extended responses with c-map What evidence from both types of assessment illustrate students’ understanding and misconceptions? Explain the phenotypic changes in the tree and the animal. Use your understanding of evolution by natural selection. Write a short answer Develop a rubric with your team 15 16 Instructional Design/Pedagogy Question • • • Do instructional designs and pedagogy that enable students to learn how to make connections among concepts affect their understanding of complex problems? Concept Map 1 -- ecosystem principles carry over Concept Map 2 -- biogeochemical cycles • principles carry over • Concept Map 3 -- natural selection • principles carry over • • • • Concept Map 4 -- inheritance principles carry over Concept Map 5 -- biodiversity Summative assessment 17 18 The Grandma Johnson Problem Summative Assessment Hypothetical Scenario: Grandma Johnson had very sentimental feelings toward Johnson Canyon, Utah where she and her late husband had honeymooned long ago. Her feelings toward this spot were such that upon her death she requested to be buried under a creosote bush overlooking the canyon. She loved the idea that she'd become part of the wonderful wilderness and live on through the wildlife that lived there. Think to yourself and begin to trace the path of a carbon atom from Grandma Johnson's (GJ) remains to where it could become part of a coyote (NOTE: the coyote WILL NOT dig up Grandma and consume any of her remains). What fundamental pathways and processes of biology will be involved in the transit of GJ's carbon atoms to that of the wild coyote in Utah? Synthesis level questions Grandma Johnson Radish Dinosaur/Tree Compare responses with control class - did not integrate concept maps 19 20 Radish problem (2) Radish Problem ! ! ! Experimental Setup: ! Weighed out 3 batches of radish seeds each weighing 1.5 g. ! Experimental treatments: » 1. Seeds placed on moistened paper towels in LIGHT » 2. Seeds placed on moistened paper towels in DARK » 3. Seeds not moistened (left DRY) placed in light After 1 week, all plant material was dried in an oven overnight (no water left) and plant biomass was measured in grams. Predict the biomass of the plant material in the various treatments. » Water, light » Water, dark » No water, light 21 Results: Weight of Radish Seedlings 1.46 g 1.63 g 22 Goal: explain evolution by natural selection 1.20 g Write an explanation about the results. 23 24 Analysis Individual Problem Coding of extended responses • Explain the phenotypic changes in Identification of misconceptions the tree and the animal.
