The
objective of this study was to develop a two-tier test about
the subject of “Separation of Matter” in 9th
grade chemistry curriculum and to argue the efficiency of
this test on students’ achievement. First, we interviewed 21
students to develop multiple-choice items. Secondly, 24
students were asked to select the most appropriate answer to
each question and then they gave explanations for their
choices to develop a two-tier test. At the third phase of
this study, a two-tier test including 15 questions was
developed and applied to141 students for collecting data.
The results of the study showed that the two-tier test was
effective on determining the students’ misconceptions and
also it might be used as an alternative to the traditional
multiple choice test for of assessment and evaluation of
alternative students’ achievement.
