New knowledge tracing models are continuously being proposed, even at a pace where state-of-the-art models cannot be compared with each other at the time of publication. This leads to a situation where ranking models is hard, and the underlying reasons of the models' performance -- be it architectural choices, hyperparameter tuning, performance…

The research aimed to find the learning model of the undergraduate students by Confirmatory Factor Analysis (CFA). The objective was design learning model. The Methods of this Study process to find the learning model of the undergraduate students is divided into two phrases. The 1st phrase: the preliminary study and the 2nd phrase: Confirmatory…

The development of reading-related phonological processing abilities represents an important developmental milestone in the process of learning to read. In this cross-sectional study, confirmatory factor analysis was used to examine the structure of phonological processing abilities in 129 younger preschoolers (M = 40.88 months, SD = 4.65) and 304…

Study conducted by the Aptitudes Research Project at the University of Southern California, under Contract Nonr-228(20) with the Office of Naval Research, Personnel and Training Branch.

A verbal concept-learning task permitting the externalizing and quantifying of learning behavior and 16 ability tests were administered to female graduate students. Data were analyzed by alpha factor analysis and incomplete image analysis. Six alpha factors and 12 image factors were extracted and orthogonally rotated. Four areas of cognitive…

A battery of memory tests was administered to 243 male university students. Factor analysis with oblique rotation of factors revealed five factors: (1) associative memory (particularly important in paired-associate tests), (2) short-term visual memory (the ability to derive information from briefly presented visual displays), (3) meaningful memory…

Eighteen retarded Ss (mean IQ 50 and mean age 14 years) and 18 normal Ss (mean IQ 100 and mean age 7 years) participated in a study to isolate variables that differentially control discrimination learning and retention processes, and to evaluate contrasting theories on discrimination learning and menory processes of retarded and normal children.…

A LEARNING MODEL TO IDENTIFY FACTORS CONTRIBUTING TO THE DIFFICULTY OF A PROBLEM ITEM WAS SUPPORTED EMPIRICALLY, AND INDICATED THAT THE NUMBER OF STEPS REQUIRED TO SOLVE A PROBLEM WAS THE MOST IMPORTANT VARIABLE IN PREDICTING BOTH ERROR PROBABILITY AND RESPONSE LATENCY. THE MODEL, IN ORDER TO ESTABLISH DIFFERENTIAL PREDICTIONS OF DIFFICULTY IN…
