Teachers develop stereotypical expectations about students, but this categorical knowledge can influence their judgments about students. Although teachers' stereotypical expectations about students have been investigated in the educational domain, this research has mostly measured only the teachers' judgments. However, the judgment is…

Multiple studies have shown benefits of problem-solving prior to instruction (cf. Productive Failure, Invention) in comparison to direct instruction. However, students' solutions prior to instruction are usually erroneous or incomplete. In analogy to "guided" discovery learning, it might therefore be fruitful to lead students…

We examined the hypothesis that interpolated testing in a multiple list paradigm protects against proactive interference by sustaining test expectancy during encoding. In both experiments, recall on the last of 5 word lists was compared between 4 conditions: a tested group who had taken tests on all previous lists, an untested group who had not…

Mathematical processing associated with solving short geometry problems requiring logical inference was examined among students who differ in their levels of general giftedness (G) and excellence in mathematics (EM) using ERP research methodology. Sixty-seven male adolescents formed four major research groups designed according to various…

A refutation text is designed to promote conceptual change by explicitly acknowledging commonly held misconceptions about a topic, directly refuting them, and providing an accurate explanation. In this study, we determined the impact of different types of refutation texts on adolescent readers' conceptual change learning in science. Specifically,…

Background: The facilitating role of sleep for language learning is well-attested in adults and to a lesser extent in infants and toddlers. However, the longitudinal relationship between sleep patterns and early vocabulary development is not well understood. Methods: This study investigates how measures of sleep are related to the development of…

Objective: Clients often have limited time in a nutrition education setting. An improved understanding of the strategies used to accurately estimate calories may help to identify areas of focused instruction to improve nutrition knowledge. Methods: A "Think Aloud" exercise was recorded during the estimation of calories in a standard dinner meal…

Previous studies have reported that infants selectively reproduce observed actions and have argued that this selectivity reflects understanding of intentions and goals, or goal-directed imitation. We reasoned that if selective imitation of goal-directed actions reflects understanding of intentions, infants should demonstrate stability across…

The aim of the study is to conceptualize the technology-aided mathematical modelling process in the frame of cognitive modelling perspective. The grounded theory approach was adopted in the study. The research was conducted with seven groups consisting of nineteen prospective mathematics teachers. The data were collected from the video records of…

The purpose of the present study was to test the efficacy of a modified cognitive strategy instructional intervention originally developed to improve the mathematical problem solving of middle and high school students with learning disabilities (LD). Fifth and sixth grade general education mathematics teachers and their students of varying ability…

The research supporting this paper addresses the problem of educational communication efficacy using a dual methodology strategy. Over 1,200 questionnaires were given out to professionals in four institutions dedicated to persuasive communication; two traditional--the church and schools--and two more recently created--journalism and advertising.…

Test results from the Program for International Student Assessment (PISA) reveal that Shanghai students performed less well in solving interactive problems (those that require uncovering necessary information) than in solving analytical problems (those having all information disclosed at the outset). Accordingly, this study investigates…

The relatively little amount of time that some college students spend reading their textbooks outside of the classroom presents a significant threat to their academic success. Using Prenksy's (2001) digital game-based learning (DGBL) principles and Astin's student involvement theory as frameworks, the purpose of this true experiment was to…

A number of studies have shown that visual working memory (WM) is poorer for complex versus simple items, traditionally accounted for by higher information load placing greater demands on encoding and storage capacity limits. Other research suggests that it may not be complexity that determines WM performance per se, but rather increased…

Darwinian evolution is difficult to understand because of conceptual barriers stemming from intuitive ideas. This study examined understanding of evolution in 52 students (M = 14.48 years, SD = 0.89) before and after a guided field trip to a natural history museum and in a comparison group of 18 students (M = 14.17 years, SD = 0.79) who did not…
