The Common Core State Standards represent the first standards document to address whether students are able to read progressively more complex texts as they progress across the grades. This article gives an overview of the three components of the model of text complexity that were identified in Appendix A of the Standards and also were the basis…

The study reviewed the evidence that persistent pain has the capacity to interrupt and consume working memory resources. It was argued that individuals with persistent pain essentially operate within a compromised neurocognitive paradigm of limited working memory resources that impairs task performance. Using cognitive load theory as a theoretical…

Drawing on research into students' understanding, this article argues that the customary approach to introductory chemistry has created difficulties for students. Instead of being based on the notion of "solids, liquids and gases", introductory chemistry should be structured to develop the concept of a substance. The concept of a…

According to national mathematics standards, algebra instruction should begin at kindergarten and continue through elementary school. Most often, teachers address algebra in the elementary grades with problems related to solving equations or understanding functions. With 789 second-grade students, we administered: (1) measures of calculations and…

Working memory is typically defined as a system devoted to the simultaneous maintenance and processing of information. However, the interplay between these 2 functions is still a matter of debate in the literature, with views ranging from complete independence to complete dependence. The time-based resource-sharing model assumes that a central…

This case study started when I noticed that my ESL (English as a Second Language) students from all over the world had a hard time not only adjusting their writing/textual production to the language but also to the organizational structures of the paragraph I was presenting to them in my intermediate writing class. Considering that my students…

Despite the impact of genetics on daily life, biology undergraduates understand some key genetics concepts poorly. One concept requiring attention is dominance, which many students understand as a fixed property of an allele or trait and regularly conflate with frequency in a population or selective advantage. We present the Dominance Concept…

Though addressing sources of uncertainty is an important part of doing science, it has largely been neglected in assessing students' scientific argumentation. In this study, we initially defined a scientific argumentation construct in four structural elements consisting of claim, justification, uncertainty qualifier, and uncertainty…

The study uses an elicited imitation (EI) task to examine the effect of the native language on the use of the English nongeneric definite article by highly proficient first-language (L1) Spanish and Russian speakers and to test the hierarchy of article difficulty first proposed by Liu and Gleason (2002). Our findings suggest that there is a clear…

Multiple-choice questions are an important part of large-scale summative assessments, such as the advanced placement (AP) chemistry exam. However, past AP chemistry exam items often lacked the ability to test conceptual understanding and higher-order cognitive skills. The redesigned AP chemistry exam shows a distinctive shift in item types toward…

Few studies investigate ELT with young learners in China, although conservative estimates suggest 60-million primary school children are studying English; even fewer studies investigate Chinese young learners' L2 motivation. This article reports on a study of English learning motivation among Chinese primary school pupils through analysing…

Educational policies and initiatives significantly influence instruction in classrooms across the nation. This article presents data from a larger critical ethnographic study in an urban school in the United States during the school's first year implementing the Common Core State Standards. In this article, the author shares data from three…

Tutoring systems provide students with various types of on-demand and context-sensitive hints. Students are required to consciously adapt their help-seeking behavior, proactively seek help in some situations, and solve problems independently without supports in other situations. We define the latter behavior as stoic behavior in hint seeking. In…

A simulation study was conducted to explore the performance of the linear logistic test model (LLTM) when the relationships between items and cognitive components were misspecified. Factors manipulated included percent of misspecification (0%, 1%, 5%, 10%, and 15%), form of misspecification (under-specification, balanced misspecification, and…

Information technology (IT) investment decision makers are required to process large volumes of complex data. An existing body of knowledge relevant to IT portfolio management (PfM), decision analysis, visual comprehension of large volumes of information, and IT investment decision making suggest Multi-Criteria Decision Making (MCDM) and…
