The Jouve-Cerebrals Crystallized Educational Scale (JCCES) has been thoroughly evaluated for its reliability and consistency. This large-scale study, involving 1,079 examinees, utilized both Classical Test Theory (CTT) and Item Response Theory (IRT) methods to analyze the scale’s performance and internal structure. Background The JCCES was developed to measure crystallized cognitive …
Abstract This study aimed to investigate the differentiation between cognitive abilities assessed by the Jouve Cerebrals Crystallized Educational Scale (JCCES) and General Ability Measure for Adults (GAMA). A sample of 63 participants completed both JCCES and GAMA subtests. Pearson correlation and factor analysis were used to analyze the data. The …
Abstract This study aimed to investigate the underlying dimensions of the Jouve Cerebrals Crystallized Educational Scale (JCCES) Mathematical Problems (MP) using Alternating Least Squares Scaling (ALSCAL). The dataset consisted of intercorrelations between 38 MP items, with 588 participants. Various dimensional solutions were assessed for the goodness of fit. A 4-dimensional …
Abstract This study aimed to examine the relationships between the Jouve Cerebrals Crystallized Educational Scale (JCCES) Crystallized Educational Index (CEI) and various measures of cognitive abilities and academic achievement. Pearson correlation analyses were used to test the research hypotheses. The results showed strong correlations between the JCCES CEI and measures …
