N2  - The aim of this study is to develop and validate student?s mathematical process instrument (ProM3). The study used ADDIE?s model involves analysis, design, development, implementation and evaluation phase. The study design used was instrument development and validation involves survey method in evaluation phase. Two instruments were developed, which a sample of problem solving task related to Form One mathematics topics along with a rubric. There are 407 Form One students of three categories of fully residential school involved as research samples. Students? responses in tasks were scored by seven raters based on developed rubric towards  five dimensions of mathematical process namely connection, representation, communication, reasoning and problem solving. The results of the evaluation analysis  by nine experts showed that the task and rubric had high content validity, with CVR values in the range of 0.8 to 1.00. The many facet Rasch model (MFRM) was used to assess the validity of ProM3 rubric in the aspects of students? abilities, raters? severity, and the items? difficulty. Rubric indicates good construct validity with positive value of PTMEA CORR (0.32-0.75), and fit statistics within the acceptable range (0.5-1.5). Dimensionality analysis showed that the instruments explained 50.40% of the mathematical process skills. Rating scale functioned well with 1.4 to 5.0 interval size. Meanwhile the measurement of item?s difficulty (+1.84--2.33 logit) correlated with the  students? ability (+4.75 --3.58 logit). Rubric also showed good item reliability (0.99) and the inter-rater agreements (48.7%). Variable map showed that the respondents were      divided into four levels of mathematical process skills; Excellent group (2.46%), Good (41.77%), Average (52.5%) and Weak (3.19%). The mean value of the students? involved who possess mathematical process skills were at the average level (-0.38 logit). In conclusion, the developed rubric had good psychometric characteristics in measuring students? mathematical process skills. This implicates that the use of the instrument can be extended to secondary school students and can be used as a model to measure the same skills for different topics.
