We analyze log-data generated by an experiment with Mathtutor, an intelligent tutoring system for fractions. The experiment compares the educational effectiveness of instruction with single and multiple graphical representations. We extract the error-making and hint-seeking behaviors of each student to characterize their learning strategy. Using an expectation-maximization approach, we cluster ...

The studies investigated if advance organizer learning will facilitate learning of some selected Government concepts among senior secondary school students in Oyo State, Nigeria. The study assessed the differences in the academic performances from low, middle, and high socio-economic backgrounds of students after they have been exposed to advance organizers learning strategy. The design for the...

This study investigated whether Lexical Inferencing (L1) and Morphological Instruction (MI) can significantly affect EFL learners’ reading comprehension, furthermore, it also examined their effects on the learners’ vocabulary retention over time. 60 homogeneous EFLlearnerswere randomly assigned to two experimental and a control groups. After the pre-test, participants of the first experimental ...

Numerous scholars have applied conceptual graphs for explanatory purposes. This study devised the ‘Remedial-Instruction Decisive path (RID path)’ algorithm for diagnosing individual student learning situation. This study focuses on conceptual graphs. According to the concepts learned by students and the weight values of relations among these concepts, this study established the remedial-instruc...

Teachers gesture when they teach, and those gestures do not always convey the same information as their speech. Gesture thus offers learners a second message. To determine whether learners take advantage of this offer, we gave 160 children in the third and fourth grades instruction in mathematical equivalence. Children were taught either one or two problem-solving strategies in speech accompani...

Studies suggest that mimicking specific gestures prior to math instruction facilitates learning. However, benefits could be due to the eye movements that accompany gesture, rather than to gesture per se. Children (M age = 8 yrs, 9 mos) who solved pretest equations incorrectly were taught a correct strategy for solving equations. They were randomly assigned to mimic gestures instantiating the st...

Cognates are the words celebrating their similarities from phonetic, orthographic, and semantic points of view across two or more languages. The aim of the present study was to investigate the effect of cognate-based instruction strategy on vocabulary learning among Iranian EFL learners. To achieve the goal of the study, 80 EFL learners (15-27 years old) took part in the study; all of them were...
