APPENDIX A: An Example of a Multiple Rating Item

Lab Conclusion Grading Rubric

Instructions: Place the grading rubric next to the lab conclusion. Read the examples of responses that represent the number score for the criteria you are grading. Read the conclusion and assign the number of points that most closely represents the type of answer given by the students. Repeat this process for all of the criteria and then add the points together in order to assign a total score.

1. Clearly Stated Conclusion. Answers problem question and explains why. (2 points)

0 - Some of the cups had more ants than others.

1 - The cups closest to the wall had more ants or cups in the dirt had more than those in the grass or more ants were found in the sunlight than the shade.

2 - Cups numbered 2 and 3 had the most ants because they were closest to the wall or the cups in the dirt had 10 more ants than those in the grass because the area was heavily traveled or it was difficult to determine if there were more ants in the sun or shade because some of our cups were vandalized but the experiment did show 2 more ants in the sun than the shade.


2. Details to Support Conclusion. Uses specific cup numbers, numbers of ants and sizes of ants or describes environment in which cups were placed. (2 points)

0 - Some cups had two ants but others had 10 ants or there was a larger population of red ants than black ants in our testing area.

1 - Cups 9 and 10 had fourteen ants but the other cups had less or the grass environment contained the most red ants with 25 followed by the dirt environment with 10 ants or we found 8 black ants and two red ants and they were all small in size.

2 - Cups 9 and 10 had fourteen ants while cup 11 had eighteen ants because they were in the shade or in the grassy area there were 59 ants compared to 20 in the dirt area and 17 in the middle area or there were 7 small black ants and one large black ant and one small red ant and one medium red ant and the ants preferred the sun over the shade.


3. Clear, detailed, elaborate. Explains why they think they got those results. (2 points)

0 - Section missing

1 - Our hypothesis was proven, there are more ants next to the wall or our hypothesis was right and ants do prefer grass over dirt or we found 5 black ants and 1 red ant in the sun and 3 black ants and 1 red ant in the shade, so ants prefer sun over shade

2 - There are several explanations of why we obtained these results, one is that ants tend to stay away from disturbed areas or 28 black ants were counted in the grass but only 4 were found in the dirt because there was more food for the ants in the grass or ants prefer the sun over the shade because there were more plants on the sunny side of our site.


APPENDIX B

CATEGORIES OF MODIFIED FLANDERS INTERACTION ANALYSIS

INDIRECT

1. Accepts or clarifies feelings: Predicting or recalling a feeling in a non-threatening manner, feelings can be positive or negative.

2. Praises or encourages: Praises or encourages action or
behavior. Humor that releases tension. "Tell me more" statements are included.

3. Accepts or uses others ideas: Clarifies, builds, or develops ideas suggested by another student.

4. Asks questions: Asks a question about content or procedure.


DIRECT

5. Lectures: Gives facts or opinions about content or procedure, expresses his or her own ideas.

6. Gives directions: Directs, commands, or gives orders.

7. Criticizes or condemns another student: statements that are made to change the behavior or opinion of another student and are negative and directed "at" another person.

8. Silence or confusion: Pause, wait time, or confusion.

DIRECT (No. 5-7) / TOTAL # OF RESPONSES = % OF DIRECT RESPONSES
