The production effect is the substantial benefit to memory of having studied information aloud as opposed to silently. MacLeod, Gopie, Hourihan, Neary, and Ozubko (2010) have explained this enhancement by suggesting that a word studied aloud acquires a distinctive encoding record and that recollecting this record supports identifying a word…

This study reports a meta-analysis on the effects of ethnic minority share in school on achievement test scores. Best evidence from the studies that have appeared thus far on this topic shows that these compositional effects appear small in general, but may be larger when the ethnic minority group is African Americans in the USA than when the…

This paper describes a multimodality approach that helps primary-school students improve their learning performance during music instruction. Multimedia instruction is an effective way to help learners create meaningful knowledge and to make referential connections between mental representations. This paper proposes a multimodal, dual-channel,…

This study examined how literal symbols affect students' understanding of algebraic expressions. Middle school students (N = 322) were randomly assigned to 1 of 3 conditions in which they were asked to interpret an expression (e.g., 4c + 3b) in a story problem. Each literal symbol represented the price of an item. In the c-and-b condition, the…

This article presents four experiments that tested predictions of SOB (Serial Order in a Box), an interference-based theory of short-term memory. Central to SOB is the concept of novelty-sensitive encoding, which holds that items are encoded to the extent that they differ from already-encoded information. On the additional assumption that…

The Hill cipher is the simplest example of a "block cipher," which takes a block of plaintext as input, and returns a block of ciphertext as output. Although it is insecure by modern standards, its simplicity means that it is well suited for the teaching of such concepts as encryption modes, and properties of cryptographic hash functions. Although…

This study examined the respective contribution of verbal working memory, which was operationalized as immediate digit and sentence recall, to bilingual children's reading fluency and comprehension in the first language (L1) and second language (L2). Fifty children from two international sites took part in this study: One group was English-Korean…

The state of higher education today is one of change and stasis. Economic vulnerability, globalization, technological innovation, and an increasingly competitive market underlie the need for change in higher education. At the same time, there are strong and stubborn forces at work supporting the status quo. Though daunting, institutions of higher…

"Voluntourism" refers to the use of "discretionary time and income to travel out of the sphere of regular activity to assist others in need" (McGehee & Santos, 2005, p. 760). These experiences have been shown to raise consciousness and increase interest in activism (McGehee, 2002; Wearing, 2001) and to build pro-social…

Purpose: Health care providers face challenges in rural service delivery due to the unique circumstances of rural living. The intersection of rural living and health care challenges can create barriers to care that providers may not be trained to navigate, resulting in burnout and high turnover. Through the exploration of experienced rural…

The purpose of this study was to develop a framework for analyzing and evaluating student-constructed models of physical phenomena and monitoring the progress of these models. Moreover, we aimed to examine whether this framework could capture differences between models created using different computer-based modeling tools; namely, computer-based…

A general outcome measure (GOM) can be used to show progress towards a long-term goal. GOMs should sample domains of behavior across ages, be sensitive to change over time, be inexpensive and easy to use, and facilitate decision making. Skinner's (1957) analysis of verbal behavior may benefit from the development of GOM. To develop GOM, we…

In the mid 1990s, Encoded Archival Description (EAD) appeared as a revolutionary technology for publishing archival finding aids on the Web. The author explores whether or not, given the advent of Web 2.0, the archival community should abandon EAD and look for something to replace it. (Contains 18 notes.)

Qualitative research methods require transparency to ensure the "trustworthiness" of the data analysis. The intricate processes of organising, coding and analysing the data are often rendered invisible in the presentation of the research findings, which requires a "leap of faith" for the reader. Computer assisted data analysis software can be used…

A critical stage in the process of developing a conceptual understanding of organic chemistry is learning to use curved arrow notation. From this stems the ability to predict reaction products and mechanisms beyond the realm of memorization. Since evaluation (i.e., testing) is known to be a key driver of student learning, it follows that a new…
