IA practice test
The following in-class assessment is a way in which I get students to practice for their internal assessment. I give this assessment when we have finished studying the Working Memory Model.
Our students all have laptops. If they have laptops, they should be able to finish this task in 45 minutes. Writing by hand may take longer. You may also want to give it as a take-home assignment or assessment.
A copy of the assessment is attached and suggestions for responses and how to assess on a 1 - 7 scale are included below.
Students are given the following "study."
Crane (2018) carried out the following study in his IB Psychology class to determine how well multi-lingual international school students can multi-task.
To begin, his 22 students were randomly allocated to one of two groups – group A or group B. Students in both groups were given an 800-word text that described a historical crime committed in the city of Prague. Group A read the text in silence for four minutes. In Group B, just as the participants started to read the text, Mr. Crane received a phone call. He spoke to the principal about a “disciplinary issue” with one of his students. The student being discussed was not named. The conversation was scripted and lasted four minutes.
After the four minutes were up, students were given a set of 10 questions to answer about the text. The questions were marked as either right or wrong. Here were the results.
A Mann Whitney U was calculated. The p-value was less than or equal to 0.01.
Questions and responses
The study is followed by four questions. Here are four model responses.
Summarize the results in your own words based on the data above.
Discuss your findings with reference to the Working Memory Model. How do these results reflect what research tells us about our ability to multi-task?
Explain the strengths and limitations of the design, sample, and procedure.
Suggest one modification to address one limitation of our investigation.
You may choose to simply give feedback on this assessment or use it for grading purposes. Below is a suggested "mark scheme" for this test.
1. Summarize the results in your own words based on the data above.
- 6 marks: the student has discussed the mean, median, and standard deviation and referred to the p-value without errors.
- 5 marks: the student has discussed the mean, median, and standard deviation and referred to the p-value but with minor errors.
- 4 marks: the student has discussed the mean, median and standardization but has not discussed the conclusions of the study with regard to the p-value.
- 3 marks: either the mean, median or standard deviation is not explained.
- 2 marks: two of the three descriptive stats are not explained.
- 1 mark: There is a minimal attempt to answer the question with very little evidence of understanding.
2. Discuss your findings with reference to the Working Memory Model. How do these results reflect what research tells us about our ability to multi-task?
- 3 marks: makes an explicit link back to the theory, demonstrating an understanding of the theory as well as the link.
- 2 marks: the study's finding is stated without reference to the theory, or the theory is explained without a link to the study.
- 1 mark: There is a minimal attempt to link the theory and the study with very little detail or evidence of understanding.
3. Explain the strengths and limitations of the design, sample, and procedure. (6 marks)
One mark is awarded for one strength and one limitation for the design, sample, and procedure for a total of six marks.
4. Suggest one modification to address one limitation of our investigation. (3 marks)
- 3 marks: a modification is clearly explained and linked to a limitation of the study.
- 2 marks: an appropriate modification is explained but not linked to a limitation of the study.
- 1 mark: a modification is identified but not explained.
