We examined the effects of applying the instructional method of constructive controversy in an animal welfare unit, on middle-school students' knowledge and attitudes relating to the treatment and welfare of animals. Accordingly, we developed and implemented a four-stage instructional model centring on constructive controversy in a class of 27…

Twenty-four studies were included in this systematic review of vocabulary research literature. The review corroborates the findings of past studies that several strategies have emerged that increase students' vocabulary knowledge. Findings further reinforce the National Reading Panel's recommendations regarding the context and magnitude of studies…

Peer victimization, or bullying, is a phenomenon that has received increasing global attention, and the use of technology, or cyberbullying, to bring about acts of bullying has certainly increased as access to various technological tools has escalated. While it is unclear whether this attention is a function of actual increases in cyberbullying or…

Middle-school students are expected to understand key components of graphs, such as slope and y-intercept. However, constructing graphs is a skill that has received relatively little research attention. This study examined students' construction of graphs of linear functions, focusing specifically on the relative difficulties of graphing slope and…

Mediation analysis is a statistical approach used to examine how the effect of an independent variable on an outcome is transmitted through an intervening variable (mediator). In this article, we provide a gentle introduction to single-level and multilevel mediation analyses. Using single-level data, we demonstrate an application of structural…

Many inquiries regarding the causal effects of policies or programs are based on research designs where the treatment assignment process is unknown, and thus valid inferences depend on tenuous assumptions about the assignment mechanism. This article draws attention to the importance of understanding the assignment mechanism in policy and program…

Background: Although psychological disengagement is a well-documented phenomenon in the academic setting, the attempts to identify its predictors are scarce. In addition, existing research has mainly focused on chronic disengagement and less is known on the determinants of situational disengagement. Aims: The purpose of the present study was to…

The present study examined how beliefs about intelligence, as mediated by ability-validation goals, predicted whether students lost or maintained levels of intrinsic motivation over the course of a single academic year. 978 third- through eighth-grade students were surveyed in the fall about their theories concerning the malleability of…

Background: Boredom has been found to be an important emotion for students' learning processes and achievement outcomes; however, the precursors of this emotion remain largely unexplored. Aim: In the current study, scales assessing the precursors to boredom in academic achievement settings were developed and tested. Sample: Participants were 1,380…

This article characterizes the development of a deep and connected body of mathematical knowledge categorized by Ball and Bass' (2003b) model of Mathematical Knowledge for Teaching (MKT), as Specialized Content Knowledge for Teaching (SCK) in algebraic reasoning and number sense. The research employed multiple cases across three years from two…

Research over the past fifteen years has investigated and developed online science inquiry environments to support students engaging in authentic scientific inquiry practices. This research has focused on developing activity structures and tools to scaffold students in engaging in different aspects of these practices, but relatively little of this…

For the thirty-seventh year, the Research and Theory Division and the Division of Instructional Design of the Association for Educational Communications and Technology (AECT) sponsored the publication of these Proceedings. Papers published in this volume were presented at the annual AECT Convention in Jacksonville, Florida. This year's Proceedings…

Research has shown that emotions play a significant role in the learning process and academic achievement. However, the fact that measurement of emotions during or after instruction usually requires written responses on lengthy research instruments has been given as a reason why researchers have tended to avoid research on this topic in…

The research involved examining the nature of the transition that students experienced in progressing to junior high school from primary school. Students' experiences were chosen as the focus of the research because the issue of substance being investigated was that of alienation. The main methodology that was used was the qualitative procedure of…

This article describes a curriculum integration project designed to help students better contextualize their learning: The High M.A.R.C.S. Project linked mathematics, art, research, collaboration, and storytelling. The article explains the project in detail, discusses sample student work from the project, and describes how the project work was…
