| Summary: | This study engaged the cognitive diagnostic assessment (CDA) to abstract the common errors in
the learning of time intervals based on pupils’ knowledge states. CDA is a feasible testing tool
that can inform us where a test taker may be prone to making errors in the tests. In this study, a
cognitive diagnostic model with six attributes and 12 test items was created to evaluate pupils’
performance in a diagnostic test on “duration of two inclusive dates”. A total of 269 primary six
pupils from 11 elementary schools participated in the study. The diagnostic test scores were
analyzed using the Artificial Neural Network which generated 12 knowledge states (KS). Result
shows that “100000” was the leading KS. The common errors associated with this KS in
hierarchical order of prominence were: (i) exclude starting date as a day in duration; (ii) error
in regrouping; (iii) compute incorrectly the sum of the two given dates; and, (iv) express
incorrectly the time measurement in months and days. These identified common errors would
provide a valuable basis for remedial teaching of the topic “Time”. It also allows mathematics
teachers to identify the inadequacy of an earlier teaching strategy and to engender an improved
approach to help struggling learners shore up their basic skills. |
