Creating a mathematical communication competency measure for grade 6 students Under the Sukhothai Primary Educational Service Area Office 1

Abstract

The objectives of this research were to obtain and determine the quality of the mathematic map measurements for students in different grades previously from 6 departments under the Tambon Administrative Organization who received learning zone 1. 2) was defined as the normal criterion. For the measurement form along with the student map map in Year 6, the agency under the Office of the Educational District must not exceed 1. The sample group was 370 Prathomsuksa 6 students studying in the second semester of the 2022 academic year of schools under the Sukhothai Primary Educational Service Area Office 1, which were selected by multiple random sampling. step Tools used in this research It is a situational measure. Data was analyzed using statistics. Content validity, classification power, confidence Consistency Index structural straightness Finding the percentile position and finding a normal score. The results of the study showed that 1) The mathematical communication competency test consisted of 3 components according to the concept of Kennedy and Tipps (1994), 8 indicator behaviors, 9 situations, and 24 questions. with an average opinion score of experts ranging from 0.67 to 1.00, with a difficulty ranging from 0.54 to 0.79, discriminant power from 0.21 to 0.41, confidence for the whole paper equal to .70 and a consistency index for the assessor equal to 0.99. 2) The model consistency index consisted of Chi-square = 20.82, p-value = 0.23, CFI = 0.98, TLI = 0.97, RMSEA = 0.04 and SRMR = 0.04 indicating that the confirmatory component analysis model of the communication performance model mathematical are consistent with empirical data and structural validity. 3) The local norms of the scale were mean = 49.44, S.D. = 7.89, with normal scores ranging from T20 to T72 divided into 5 levels: very good, good, fair, improvement and need improvement.
