Abstract

ABSTRACT

                The objectives of the research were to 1) create of cognitive in numerical processing in lower secondary school students based on abstract code model and 2) explore the quality of cognitive in numerical processing in lower secondary school students based on abstract code model. The research population composed of 353 lower secondary school students of Chalerm Prah Kiet Samdech Prah Sinakarin School, Sisaket enrolling in semester 2 of the academic year 2014. The research materials were mathematics problem solving skill questionnaire developed according to Abstract Code Model Framework for lower secondary school students. The research findings indicated that:

1. The result of the creation of the questionnaire related to the cognitive in numerical processing of lower secondary school students; the total questionnaire created was 20 comprehension questions–first element of 8 items related to conversation symbol comprehension, second element of 5 items related to calculation and third element of 7 items related response production system.


2. The result of searching for the quality of the cognitive in numerical processing in lower secondary school students was acceptable quality that is the questionnaire was with meaning validity considered on the Index  of  Item–Objective  Congruence (IOC) of the experts revealed that it was at .67 up, the percentage of easiness was between .22–.80 and the difference value (D) was from .30 with the credibility rate of 0.84; the structure validity was with the Index  of  Item–Objective  Congruence in accordance with Abstract Code Model. The conformation analysis showed that the Goodness of Fit Index (GFI) was at 0.92, the Adjusted Goodness of Fit Index (AGFI) was at 0.90, the Root Mean Squared Residual was at 0.02. This revealed that the questionnaire of the mathematics problem solving skill of the lower secondary school students was of structure consonant with the quality corresponding to the determined criteria
