EvolutionLab Assignment 1 Scoring Rubric Exemplary Report: 5 pts. The concepts of directional, stabilizing and disruptive selection are clearly understood and are used appropriately to describe the results of the selection experiments. Average responses and selection coefficients are calculated correctly and are properly interpreted as to their significance to evolution. Student clearly understands what the coefficients represent and can explain the reasons for any differences over time or between islands. Student grasps the effects of selection on population size and can explain how evolution can cause a change in population numbers. The report shows a clear understanding of the genetics covered up to this point in class that is applicaple to this problem, is neat and well organized, with no superfulous or unexplained results. Satisfactory Report: 4 pts. The concepts of directional, stabilizing and disruptive selection are clearly understood and are used appropriately to describe the results of the selection experiments. Average responses and selection coefficients are calculated correctly and are properly interpreted as to their significance to evolution. Student clearly understands what the coefficients represent and can explain some of the differences over time or between islands. Student grasps the effects of selection on population size but doesn't explain clearly how evolution can cause a change in population numbers. The report is not always clearly written but everything asked for is there. Serious Flaws But Nearly Satisfactory: 3 pts. The concepts of directional, stabilizing and disruptive selection are clearly understood and are used appropriately to describe the results of the selection experiments. Average responses and selection coefficients are calculated correctly and aren't properly interpreted as to their significance to evolution. Student can not explain what the coefficients represent or why there are differences over time or between islands. Student grasps the effects of selection on population size but doesn't explain clearly how evolution can cause a change in population numbers. The report is not always clearly written but everything asked for is there. Begins, But Fails to complete Problem: 2 pts. The concepts of directional, stabilizing and disruptive selection are clearly understood and are used appropriately to describe the results of the selection experiments. Average responses and selection coefficients are not calculated correctly and aren't properly interpreted as to their significance to evolution. Student can not explain what the coefficients represent or why there are differences over time or between islands. Student grasps the effects of selection on population size but doesn't explain clearly how evolution can cause a change in population numbers. The report is not clearly written and is incomplete. Unable to Begin Effectively: 1 pt. The concepts of directional, stabilizing and disruptive selection are not understood and are used inappropriately to describe the results of the selection experiments. Average responses and selection coefficients are not calculated correctly and aren't properly interpreted as to their significance to evolution. Student can not explain what the coefficients represent or why there are differences over time or between islands. Student doesn't understand the effects of selection on population size and doesn't explain clearly how evolution can cause a change in population numbers. The report is not clearly written and is incomplete. No Attempt: 0 pts. Bell CSU Chico Library This document is copyright of Jeff Bell Last Update: Sunday, February 20, 2000
