Abstract

This study discusses the validity and reliability of the instrument for the purpose of evaluating the constructed research questionnaire. All items were developed from various theories and models of language literacy, as well as domestic and international literature studies. There are four constructs in measuring the language literacy development of special remedial pupils at risk of dyslexia in primary school, namely letters, syllables and words, simple sentences and text. The pilot study that has been carried out involves 34 remedial teachers as respondents. A total of five panelists were involved as content validity experts. In addition, to determine whether the item should be retained or dropped, a quantitative measurement method, the Content Validity Ratio (CVR), is used. As a result, 19 out of 52 items were dropped while another 33 items were retained. Next, the reliability of the instrument was assessed through Cronbach's alpha internal consistency method by obtaining at least 0.84 and above for each instrument construct. In conclusion, the results of the study show that all the constructs and items that were built meet the instrument's measurement requirements and can be used as a tool in measuring the language literacy development of special remedial students at risk of dyslexia in primary schools.
