The relation between intelligence and speed of auditory discrimination was investigated during an auditory oddball task with backward masking. In target discrimination conditions that varied in the interval between the target and the masking stimuli and in the tonal frequency of the target and masking stimuli, higher ability participants (HA)…

To test preschoolers' ability to flexibly switch between abstract rules differing in difficulty, ninety-three 3-, 4-, and 5-year-olds were instructed to switch from an (easier) shape-sorting to a (harder) function-sorting rule, or vice versa. Children learned one rule, sorted four test sets, then learned the other rule, and sorted four more sets.…

This research explored the absolute accuracy of judgments of learning (JOLs), wherein absolute accuracy pertains to how well the magnitude of the participant's predictions of recall correspond to his or her subsequent recall. The Anchoring Hypothesis proposes that the magnitude of JOLs does not change systematically with item difficulty; analogous…

Children with dyslexia are believed to have very poor phonological skills for which they compensate, to some extent, through relatively well-developed knowledge of letter patterns. We tested this view in Study 1 by comparing 25 dyslexic children and 25 younger normal children, chosen so that both groups performed, on average, at a second-grade…

This study determines the relative difficulty and associated strategy use of arithmetic (addition and subtraction) story problems when presented in American Sign Language to primary level (K-3) deaf and hard-of-hearing students. Results showed that deaf and hard-of-hearing students may consider and respond to arithmetic story problems differently…

Recent studies have shown that restricting review and answer change opportunities on computerized adaptive tests (CATs) to items within successive blocks reduces time spent in review, satisfies most examinees' desires for review, and controls against distortion in proficiency estimates resulting from intentional incorrect answering of items prior…

In today's higher education, high quality assessments play an important role. Little is known, however, about the degree to which assessments are correctly aimed at the students' levels of competence in relation to the defined learning goals. This article reviews previous research into teachers' and students' perceptions of item difficulty. It…

The perceptions of a group of 5-6-year olds were tested against two disparate hypotheses, one for nested hierarchies, the other for symbolic representations in language and learning. There is evidence that young children have the foundation for tackling more sophisticated and challenging ideas than is usually recognised. Linguistically, children…

This article analyzes the dynamical interaction between the maturing organism, the environment, and the task. It demonstrates the importance of the early acquisition of fundamental motor skills, and the evidence of a proficiency barrier to combining skills when the fundamental motor skills have not been acquired. Teachers need to teach using a…

These proceedings contain the papers of the International Conference on Mobile Learning 2013, which was organised by the International Association for Development of the Information Society, in Lisbon, Portugal, March 14-16, 2013. The Mobile Learning 2013 International Conference seeks to provide a forum for the presentation and discussion of…

The study examines the interests and attitudes of school students toward biology: through their interest in out-of-school activities and their attitude towards lessons as measured by interest, importance and difficulty. Biology lessons were relatively popular with the greatest preference found among students learning zoology. Girls showed…

The role of explicit and implicit acquisition of grammatical rules in second language learning was examined by assessing high school students performance after several years of study on the correct use of the Spanish verbs "ser" and "estar". These two verbs are essentially equivalent in use to the English verb "to be," but there is a complex set…

Family and consumer sciences programs in higher education operate in a dynamic environment of self-evaluation. One common component of the process is the evaluation of teaching effectiveness. This study reviewed some of the critical perspectives on student surveys of teaching effectiveness and then tested a portion of that dialogue by…

Three interactive tasks, increasing in the complexity of resource-directing reasoning demands on speaker/storyteller attribution of, and linguistic reference to, the thoughts and intentions of characters in narrative stimuli were performed by Japanese L1 speakers of English. Largely consistent with the claims of the Cognition Hypothesis, results…

"The Critical Word Factor," based on word recognition demands of texts, is a measure of text difficulty designed specifically for texts used by beginning readers. The measure is a function of the number of new, unique words per 100 running words of text that fall outside a designated curriculum. The authors investigated the validity of the…
