In elementary mathematics instruction, teachers often compromise access and cognitive demand in pursuit of one or the other. I explored how five different co-teaching models impact students' access to cognitively demanding mathematical learning opportunities (MLOs) in elementary classrooms. Through ethnographic lesson observations, artifact…

Background: As a result of the COVID-19 pandemic, many teachers found themselves making a rapid and often challenging shift from in-person classroom teaching to teaching in an online environment. As teachers continue to learn about working in this new environment, research in cognitive and learning sciences, specifically findings from cognitive…

The rise of online courses has created an ongoing demand for instructional designers in higher education. Collaboration between faculty and instructional designers in developing online engineering courses has therefore increased. Potential challenges during the collaboration can be addressed when faculty and instructional designers have a mutual…

Graphic novels are a form of authentic text that have started to gain widespread acceptance in the English language arts field and have been shown to increase students' motivation to read and engage deeply with texts. By integrating text with pictures, graphic novels have the advantage of requiring a lighter cognitive load than traditional…

In this paper a sequence of nine, easy to manufacture optical black-box experiments with increasing levels of difficulty, and supportive frameworks for physics classes are introduced. They have been evaluated in a lower-secondary school at the end of optics lessons. A black-box is a kind of experimental task where the inner structure is not…

This article offers guidance to teachers and students in selecting materials for extensive reading (ER). First, the article explains characteristics of ER and reviews some of the potential gains for students who do ER. Second, the article considers criteria for teachers to bear in mind when selecting ER materials. Third, the article then suggests…

The discussion about rigor is not new. Ever since the release of A Nation at Risk (1983) the debate about the quality of American schools has continued. Adoption of No Child Left Behind (2001) raised the debate to a new level. For the first time schools were held accountable for the achievement of every child, not just the most capable. Across the…

Simulation games can play a critical role in enabling students to navigate the problem spaces of the past while simultaneously critiquing the models designers offer to represent those problem spaces. There is much to be gained through their use. This includes rich opportunities for students to engage the past as independent historians; to consider…

This paper presents a goal-based scenario approach to teaching introductory database concepts to undergraduates using two different scaffolding methods. One method, termed "worked-out examples," attempts to reduce extraneous cognitive load by requiring students to complete increasingly complex missing parts of worked out examples. The other…

Four autistic children, age 8-15, exhibited fewer correct responses to a stimulus as the number of stimulus components was increased from 1 to 4. Training was effective in producing some generalized increases in responses to complex stimuli. (Author/JDD)

The study reported in this paper investigated the effects of a frequently recommended study technique on the comprehension of expository text by high-school students having learning disabilities. The instructional procedure studied was "Survey, Question, Read, Recite, Review" (SQ3R). Six experiments were conducted over a 3-year period,…

A study investigated the attitudes of adult university students of English as a Second Language (ESL) toward use of closed captioned television (CCTV) as an instructional tool. Students at the intermediate (n=51) and advanced (n=55) levels of ESL study in classes using CCTV were administered a questionnaire concerning their perceptions of the…

This manual was developed as part of a project investigating the effectiveness of class-wide peer mediated reading instruction with middle grade students having mild disabilities and reading difficulties. It explains the procedures for introducing, implementing, and monitoring the project's version of repeated reading, in which pairs of students…
