This study assessed the efficacy of the spaced learning method compared to the activity-oriented method in improving chemistry achievement among high school students, focusing on different cognitive domains. An experimental design involving pre and post-test control groups was employed, with 106 students from two schools participating. The…

This study aims to determine the relationships between mental effort and the use of learner controls while working with instructional software. Various versions of instructional software including control components were developed to examine this relationship. Twenty-four secondary school students participated in the study and studied with…

Instructional tasks and assignments can often generate severe and high rates of problem behaviors for some students in special and general education. These daily instructional assignments or tasks often pose an aversive condition, thus favoring behaviors that effectively escape such a condition as functional. The author asks the rhetorical…

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…

Previous research has indicated the disconnect between example-based research focusing on worked examples (WEs) and that focusing on modeling examples. The purpose of this study was to examine and compare the effect of four different types of examples from the two separate lines of research, including standard WEs, erroneous WEs, expert (masterly)…

The related constructs of opportunity to learn (OTL) and achievement growth are fundamental aspects of the current large-scale assessment and accountability system in operation in the United States. For purposes of this article, OTL is defined as the degree to which a teacher dedicates instructional time and content coverage to the intended…

This article reviews research on the effects of conversational style on learning. Studies of conversational style have variously investigated "personalization" through changing instances of first-person address to second or third person, including sentences that directly address the learner; including more polite forms of address; and…

This study sought to understand how aspects of middle school mathematics teachers' knowledge and conceptions are related to their enactment of cognitively demanding tasks. I defined the enactment of cognitively demanding tasks to involve task selection and maintenance of the cognitive demand of high-level tasks and examined those two…

This study investigates problem-solving difficulties of novices in a classroom setting, using a German instructional tool, the Fischertechnik kit of approximately 400 parts. In order to analyse the students' thinking processes as they solved the problems, verbal protocol analysis (VPA) was used to record the students'' thinking processes and…

Cognitive load theorists claim that problem-centered instruction is not an effective instruction because it is not compatible with human cognitive structure. They argue that the nature of problem-centered instruction tends to over-load learner working memory capacity. That is why many problem-centered practices fail. To better support students and…

A large body of research has shown that for novice learners, instruction that relies more heavily on worked examples than on problem solving, is more effective for learning as shown by higher test performance. Moreover, this beneficial effect is often obtained with less acquisition time and lower cognitive load during acquisition and test phase.…

This study is about engagement in adult literacy education. Engagement is mental effort focused on learning. It is important to understand how and why adult learners engage in literacy instruction because engagement is a precondition to learning progress. Researchers who study engagement conceive of it in different ways. Some focus on engagement…

Much effort has been invested in time-on-task research. Time-on-task is described as a proxy term for the notion of "attention," and the findings of time-on-task research are described as less relevant to the classroom teacher than information contained in methods texts. (JN)

Three researchers, addressing the problem of instructional improvement, identify sound research findings and cite problems associated with the transfer of these findings into classroom practice. Donald M. Medley, in "An Overview of Research on Classroom Teaching," identifies three variables which consistently differentiate between effective and…

Cognitive research of the 1970s has shown that both content factors (topical world knowledge and knowledge about textual organization) and process factors (attention, encoding, inference, retrieval, and executive monitoring) influence comprehension. Classroom research during the same decade has shown that the greater the proportion of time…
