The assessments included fourteen tasks related to the material world strand of the science curriculum.
Seven tasks were identical or had many common components for year 4 and year 8 students. Four of these are trend tasks (fully described with data for both 1995 and 1999), one is a released task (fully described with data for 1999 only), and two are link tasks (to be used again in 2003 so only partially described here). Three other tasks, including one link task, were attempted only by year 4 students. The remaining four tasks, including a trend task and two link tasks, were attempted only by year 8 students.
The task details and results for trend tasks are presented in the first section, followed by the task details and results for released tasks. The third section contains a little task information and the results for the link tasks. Within each of the three sections, tasks used with both year 4 and year 8 students are presented first, followed by tasks used only with year 4 students and then by tasks used only with year 8 students.
results for year 4 and year 8 students
results: Comparing 1995 and 1999 results
Five trend tasks involving 26 task components were administered to year 8 students in both the 1995 and 1999 assessments. More 1999 than 1995 students succeeded on 15 components, more 1995 than 1999 students succeeded on ten components, and there was no difference on the final component. Averaged across the 26 components, two percent more students succeeded in 1999 than 1995. Again, this difference is not large enough to be important.
