Abstract

Teaching mathematics and sciences in English makes more polemic in society in our country and some peoples give opinions whether positive or negative. A good evaluation should evaluate student in mother tongue to give them changes to responses what they know about some thinks. However, using alternative item which was modified can helps students to achieve higher score without deficient the integrity of test. Research on dependability and mathematics achievement model Form 2 is to get more information about aspects that contribute to respondent achievement. Particularly, the research is to determine dependability of scoring using Generalizability Theory and to clarify how the variables selected influence student score. This research involved 500 students Form 2 in Kedah. Data collected by instrument such as achievement test and questionnaire. Generalizability Theory state that the main source to contribute variability of score is person and not to item. This research confirms that dependability of mathematic achievement score comes from facet person which contribute more than 60% variance. Research also found that item modification help students to get a better achievement than original test item. T-test show the different significant between original test score and modification test score (t(499) =36.52, p<0.001) mean that item modification can helps students to understand the question better than original test item. Analysis for fit model show that model fit to data (χ²=190.33, df=84, GFI=0.95, TLI=0.95, RMSEA=0.05). More than 90% variance can explain mathematics achievement. According to the research, the significant predictor to mathematics achievement is attitude toward Mathematic and English for rural school and for male and female student. Beside that, teaching mathematic in English make majority of student feel uncomfortable because they difficult to followed the lesson. The situasion makes mathematic teachers teaching in both languages, Malay language and English language to make sure students understand.
