Question

Question:

Is there a correlation between students’ concept map and their written explanation of a problem?

Methods:

1. Develop a diagnostic problem

2. Build into instructional design

3. Student complete as homework

4. Develop coding scheme and analyze


The grandma johnson problem

The Grandma Johnson Problem

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?


Question

Task: Create a concept map that illustrates your understanding of the relationship between these 10 concepts in the context of the Grandma Johnson problem. You may add up to 5 extra concepts if you need them to explain the problem more clearly.

1. Work on the problem individually first, save it in CTOOLS, and print a hard copy. 2. Work on the problem with a partner. Both of you can retrieve your concept maps, discuss, revise and produce the best final map to which both of you have contributed. 3. Submit all three maps - yours, your partner's and the FINAL MAP you completed together - Please put the final map on top, with both of your names. Staple them together (5 pts off if not stapled).


The spider monkey problem

The Spider Monkey Problem

Deep within the remote forest of Guatemala, the

remains of a spider monkey were buried under an

enormous mahogany tree. Although rare, jaguars have

been spotted in this forest by local farmers. Use

coherently written sentences and clearly labeled

drawings to explain how a carbon atom in glucose

contained within the muscle cells of the spider monkey

might become part of a cell within the stomach lining

of a jaguar. Provide a written description of the

processes AND organisms the carbon atom must go

through to cycle through the ecosystem. Include a

clearly labeled drawing of the system. (Note: the

jaguar does not dig up the monkey and eat the

remains!)


Question

Task: Create a concept map that illustrates your understanding of the hierarchy and relationships between these 10 concepts:

Coding criteria

Each key concept coded

correct [C]

incorrect [I]

non-informative [N]

absent [A]

for both concept map and extended response.

Each key concept counted as a

Match:same coding on map and writing or

Nomatch: different coding on map and writing

The plant adaptation problem

The Plant Adaptation Problem

Problem: In this course, we have

claimed that land plants were the

first truly terrestrial organisms.

However, most biologists contend

that the saturated soils on land

were undoubtedly teaming with

bacteria, archaea, and protists

long before land plants evolved.

In light of this, what does the

phrase "truly terrestrial” mean?

To answer this question follow

these instructions:


Task make a concept map using the following concepts

Task: Make a concept map using the following concepts:

2. PRINT one copy for yourself then SUBMIT a copy electronically. 3. Then, using your concept map, write a short response to answer the question by explaining the problems plants had to overcome to live on land and explain the adaptations that allowed plants to overcome those problems. 4. After you finish you short response, print it out and use a highlighter to highlight the statements (propositions) you used directly from your concept map. You should have elaborated (explained) further upon these statements in your written response.5. Hand in hard copy of (a) concept map and (b) written, highlighted answer.
