4. Introduction (a)
Background of the Study
• To enter science-based studies in the
University of Botswana, students graduating
from the secondary school have to take the
Pre-Entry Science Course (PESC).
• Because of students’ poor performances in
science and Mathematics, they can hardly pass
the course.
4

5. Introduction (b)
Purpose of the Study
• By applying the Computer-Assisted Learning
(CAL), students are hoped to learn better in
their algebra and correct their misconceptions.
5

6. Introduction (c)
Research Questions
RQ1:
• Does the software cause a significant increase in
the general students’ performances in basic
algebra?
RQ2:
• Is there any indication of significant differences
with respect to the misconceptions of students ?
6

7. Literature Review (a)
Teaching through software system
• Confrey (1991) stated that in terms of
achieving students’ successful learning, the
personally reasonable ways are suggested.
• Therefore, a survey was conducted to collect
the students’ conceptual difficulties used in
this study.
7

8. Literature Review (b)
Teaching through software system
• Staal and Geveling (1987) supported with the
idea that CAL should be a part integrated into
the curriculum.
8

9. Literature Review (c)
Teaching through software system
• Whitton Ayers and Bitter (1988) indicated that
the computer programs applied in the
mathematics instructions can highly and
independently motivate the students’ learning.

10. Method (a)
Descriptive Information
• The study:
– The participants: 260 students
– The grouping: X (Experimental) & Y (Control)
• Instrumental Packages:
– Basic Algebra Tests (BAT): A (open-ended questions),
B (Multiple Choice), and C (Multiple Choice)
– 32 computers
– Questionnaire

11. Method (b)
Data Collecting Procedure
11

12. Method (c)
Internal Consistency of the testing tools
The split-half correlation
values are too low !!!
12

13. Results and Discussion (a)
Performances of the two groups on the three tests
The standard deviation
values are too large !!!
13

14. Results and Discussion (b)
Performances on three ability groups
14

15. Results and Discussion (c)
Item Analysis
15

16. Results and Discussion (d)
Discussion
Answering RQ1
• With the help of the software, students in
group X performed better.
Answering RQ2
• The misconceptions were reduced by the
ongoing instruction.
16

17. Results and Discussion (e)
Discussion
• The questionnaire administered after the whole
instructional procedure showed that students
provided positive feedbacks toward
instructions through the computer software.
17

18. Conclusion
Pedagogical Implication
• Through computer software instructions,
students’ intuitions for mathematics are
sharpened.
• CAL is highly suggested in developing
countries.
18

19. Is this article
well-written ?
19

20. My Critique
• The content was not well-organized.
• There were too many descriptions on the
operation of the university course.
• Instrumentation section was not clear enough
for readers to easily follow.
• Statistical packages were not introduced.
• Test-retest reliability is suggested.
• Grouping could be controlled in a better way.
