Student survey results

From GeoMod

Student pre survey What factors impact gully formation?

Rank
1) Seasons, weather, and amount of precipitation
2) Causes of gully formation unknown
3) Mass wasting process attributed to rain
4) Slope

What are possible anthropogenic causes of gully formation?

Rank
1) agriculture and urbanization
2) digging ? students may have meant extraction eg. strip mining
3) relationship unknown human activity and gully formation
4) other sources, pollution, logging, fishing

Student formed hypothesis on gully erosion

61% indicated belief, increase in slope would increase formation of gully features
22% indicated a belief, decrease in slope would increase formation of gully features

Student formed hypothesis sediment transport increase due to slope increase.
almost all students at this portionm of the lab indicated that an increase in slope would increase sediment transport capacity

Student responses to question: How can this lab be improved?

Rank
1) simplify presentation of formulas
2) improve visual impact of model, make it more realistic
3) reduce compexity of material
4) focus on explanation of material during lab
5) provide background material before lab presentation
