- PSY 360 is a required Psychology course for undergraduates.
- Students learn about basic principles of behavior analysis in a
structured manner.
- They are provided with homework assignments, vocabulary flashcards, and
other assigned sections to increase their knowledge and understanding of
behavior analysis.
|
|
3
|
- Students also read Elementary Principles of Behavior (EPB), which
analyzes case studies using contingency diagrams.
- They complete homework for each seminar to give them practice
diagramming the contingencies.
Often the quizzes include contingency diagrams.
|
|
4
|
- The Seminar meets on Tuesdays and Thursdays for approximately 2 hours.
- The TAs discuss the agenda, homework, EPB, and probe questions.
- Students show their original examples of a contingency diagram on
transparencies to the class.
|
|
5
|
- The goal of PSY 360 is to produce undergraduate students who use the
principles of behavior analysis in their personal and professional life.
- One of the primary purposes of PSY 360 is for the students to identify
examples of the eight basic contingencies.
|
|
6
|
- In order to achieve the goal of producing competent undergraduates, we
analyze PSY 360 using the six steps of behavioral systems analysis.
- This helps those involved with PSY 360 accomplish the goal in an
organized and efficient manner.
|
|
7
|
- 1. Analyze the Natural
Contingencies: Why do students confuse one basic contingency for
another?
- 2. Specify the Performance
Objectives: What do we need to do in order to achieve our goal?
- Students should discriminate between the eight basic contingencies.
- 3. Design an Intervention: What
is the best way to get to our goal?
- Develop Programmed Instruction specifically for those common
misconceptions.
|
|
8
|
- 4. Implement the Intervention:
- Add the Programmed Instruction as a new homework assignment to PSY 360.
- 5. Evaluate the Intervention: Did it work or not work and how well did
it work or not work?
- Compare past posttest performance to this semester’s posttest
performance.
- 6. Recycle through the previous steps until we achieve our performance
objectives.
|
|
9
|
- Students have consistently confused certain contingencies with other
contingencies when given a description.
- We discovered these problems in two ways.
|
|
10
|
- First, we analyzed posttest results from the previous two semesters
(Winter and Summer 2002).
- We specifically looked at questions that 10% or more students answered
incorrectly.
- We further looked for specific contingencies the students chose as the
wrong answer.
- These answers lead us to the common misconceptions.
|
|
11
|
- The posttest is a 20 question test the students take at the end of the
semester.
- Each question is a description of a behavioral interaction of a person
or animal.
- They must choose one of the 8 basic contingencies from a list that best describes the scenario.
|
|
12
|
|
|
13
|
- The following slide is a table from the Common Misconceptions homework.
- This shows the results of the posttest analysis for the top commonly
missed contingencies.
- The results are for a total of 91 students from Summer and Winter 2002
semesters.
|
|
14
|
|
|
15
|
- Either the TAs are not comparing and contrasting the contingencies
during the seminar or they were not aware of these common misconceptions
and thus did not discuss these misconceptions.
- The homework also does not address these misconceptions at all.
|
|
16
|
- Now let’s analyze the students’ natural contingencies. We will first view an example from an
existing programmed instruction of students failing to identify the
correct contingency.
|
|
17
|
- “In the middle of scarfing down his oats, Sid belches with pride. His wife Dawn picks up his steaming
bowl of rolled oats and she tosses the entire delicacy into the compost
bucket. Somehow in the future,
Sid finds himself less likely to display his gustatory pleasure with a
belch.”
|
|
18
|
- The correct contingency would look like this:
- But, the students identify it as this:
|
|
19
|
- 25% of a total of 70 students are saying this contingency is a
punishment by the prevention of the presentation of a reinforcer instead
of the correct answer of penalty.
- They are failing to identify that the reinforcer is present in the
before condition. They are
focusing on the after condition and seeing that the reinforcer is no
longer present.
|
|
20
|
- There are no natural contingencies for training the subtle distinctions
of these discriminations. Unless we force the students to discriminate,
they will not notice them easily.
|
|
21
|
- The objectives of this Chapter homework is to clarify the common
misconceptions and therefore, increase the students’ posttest scores.
- Hopefully by identifying the behaviors involved with the misconceptions
and training them directly, the students will follow this strategy and
identify them correctly.
|
|
22
|
- Because there were no prior materials in PSY 360 that focused on the
common misconceptions of the eight basic contingencies, we decided to
create a homework assignment focusing on these problems.
|
|
23
|
- As a result of these analyses, we developed the assignment based on the
common misconceptions determined by the posttest results.
- We performed one-to-one testing with students in PSY 360.
- However, these students did not
provide much information because they all ready could identify most of
the common misconceptions.
|
|
24
|
- We also distributed the assignment to a supplementary course of PSY 360.
- These students finished the assignment and received points contingent on
providing comments and suggestions for the assignment.
- This is where we received the most help in terms of the revision
process.
|
|
25
|
- The students must complete the homework assignment before the next
seminar or they will lose 20 points.
- At this moment, the homework will be distributed to the students at the
beginning of April.
|
|
26
|
- The TAs will distribute the homework to their students during the
seminar providing the instructions to finish the assignment for the
following seminar.
- The students will be reminded of the point value of the homework.
- This homework also affects their overall homework grade in the PSY 360
course.
|
|
27
|
- We plan to provide a pretest before and a posttest after the homework to
all students.
- This pretest and posttest will be similar to the posttest they will take
at the end of the course.
|
|
28
|
- We will then compare the posttest scores to the pretest scores to
determine if the homework did indeed reduce the common
misconceptions. We will also
compare the end-of-the semester posttest with previous semesters’
posttest results to determine if there was an increase in posttest
scores because of the new programmed instruction.
|
|
29
|
- We will recycle through the previous steps until we have achieved the
performance objectives of increasing their posttest scores.
- This semester, we have been revising the homework to make it more
specific to the problems we saw from the posttest data.
|
|
30
|
- We first reanalyzed the posttest data and entered this data into the
homework. We ordered the
misconceptions from the most to least mistakes.
- Then we arranged the sections according to this ranking. We will provide more examples for
those common misconceptions that have more mistakes on the posttest.
|
|
31
|
- We also plan on performing alpha testing with Doctoral and Masters
students to ensure we are identifying the common misconceptions clearly.
- They will complete it just as the PSY 360 students will do for seminar.
- Based on their results, we will make the final necessary revisions to
the homework before distributing it to the students.
|
|
32
|
- Then we will distribute the homework to the TAs to give to their
students.
- The TAs will complete an analysis of the errors students commonly made
on the assignment.
- These errors will be discussed at the TA meeting and solutions to these
problems will be proposed.
|
|
33
|
- These proposed revisions will be made to the homework assignment in a
new version.
- Finally, this revised assignment will be placed in the coursepack for
the following semester.
|

Frakes and Ben Rottschafer, for all of their hard work and dedication to
this project.
- Thank you for attending this presentation.
