Lab Assignment #2:
Bransford and Johnson Context Study
1) Conduct multiple group experiment (aka, one factor w/ MORE than two groups)
2) Introduce results and drawing conclusions from data, working with SPSS, and reading SPSS
output (note, stress the importance that computers play in research, and how it might differ
from focus on hand calculations in 210)
3) Introduce how to graph and summarize the outcome of an experiment
4) Provide experience for the second writing assignment:
Method, Results, Figure, Figure
Caption, and Title Page
And, second opportunity to continue to build/practice on goals of first project:
Practice and improve writing a method section
Practice using terminology (IV/DV/Control variable and Between/Within-subject design)
Again, provide experience of being a research participant
Model proper experimental materials (e.g., consent form, written stimulus materials,
debriefing) and how to conduct a study (also provide students with a copy of all materials at the
end of the session).
Single factor, with three levels (between subjects)
Context provided for passage (No Context, Context Before, Context After)
Number of ideas recalled and
Variables: Passage that was played was taped (so consistent in how presented across conditions),
Time (controlled for Distractor Task (2 min) and Recall Task (5 min) and how long
the picture was viewed (30 secs), OTHERS_________________???
Participants who receive context (the appropriate pre-requisite knowledge to put into
context what they are about to hear) should be able to comprehend the passage quite
easily and recall it relatively well.
On the other hand, Ps who do not have appropriate
context (No Context Condition) should find the passage both difficult to understand
Also, B & J predicted that contextual information is necessary for the
ongoing process of comprehension (i.e., before encoding), so predicted that the
Context After Condition should also have difficulty understanding and recalling the
made by Becky Addington for ideas
on Discussion and Hypotheses that could be tested.
