Abstract

• The main aim of this study is to construct two parallel test forms for Grade 10 Mathematics. It is mainly concerned with test construction and planning and test items analysis. A table of specifications was first developed with selected chapters. Then, two parallel forms for Grade (10) Mathematics Course were developed according to the similar content, same specifications and nearly equal item characteristics. These two forms were administered to 990 Grade (10) students from seven Basic Education High Schools in Maharaungmyae Township, Mandalay Region. Descriptive research design and quantitative survey method were used in this study. For pilot testing, 80 multiple-choice (MC) items for each form were applied. These items were analyzed by using Item Analysis Technique. Then, each form consisting of 40 items were administered to students for the main study. From 40 items of each form, 17 pairs of items are selected as parallel items according to their similar levels and ranges of difficulties and discriminations. Since the raw score means of two forms are 8.5010 and 8.5232, both forms have strong positive relationship. Then, paired samples correlations were calculated to assess the parallel (equivalent) form reliability of the scores. The closer to 1.00 the coefficient of reliability, the more consistent scores obtained form an instrument. The correlation between the sets of scores is r = .902, which is a high correlation and indicates a strong association between the scores to provide good support for parallel form reliability. The paired samples test showed that the means of Form A and Form B are not significantly different. It indicates that the same students tended to score high (or low) on both forms. Finally, it can be concluded that Form A was actually an alternate form or version of Form B that was supposed to be equivalent.
