Wicked problems are multifactorial in nature and possess no clear resolution due to numerous community stakeholder involvement. We demonstrate childhood lead poisoning as a wicked problem and illustrate how understanding a community's ecology can build community capacity to affect local environmental management by (1) forming an academic-community…

The production of written syntheses, which requires reading various sources and integrating information from these sources into one's own text, has been characterised as a potentially useful task for promoting constructive learning. This article describes research aimed at examining and characterising written syntheses and the processes involved…

Complexity, accuracy, and fluency have proved useful measures of second language performance. The present article will re-examine these measures themselves, arguing that fluency needs to be rethought if it is to be measured effectively, and that the three general measures need to be supplemented by measures of lexical use. Building upon this…

Academic tasks that include easy responses increase the probability that less preferred and/or more challenging tasks will be performed. The current study applied the process of arranging easier stimuli within reading word lists with behavioral momentum and an interspersal technique. We hypothesized that the behavioral momentum condition, which…

Comprehension of complex science topics occurs from the creation of new understanding of the information by the learner. However, learners are not very successful generating their own meaning, especially in computer based learning environments in which learners are required to make decisions about their learning process, since they rarely regulate…

In operational testing programs using item response theory (IRT), item parameter invariance is threatened when an item appears in a different location on the live test than it did when it was field tested. This study utilizes data from a large state's assessments to model change in Rasch item difficulty (RID) as a function of item position change,…

Numerous studies have compared the Angoff standard-setting procedure to other standard-setting methods, but relatively few studies have evaluated the procedure based on internal criteria. This study uses a generalizability theory framework to evaluate the stability of the estimated cut score. To provide a measure of internal consistency, this…

The selection of K-12 mathematics curricula has become a polarizing issue for schools, teachers, parents, and other educators and has raised important questions about the long-term influence of these curricula. This study examined the impact of participation in either a National Science Foundation-funded or commercially developed mathematics…

Practitioners in youth settings experience life on the ground as a tumble of events, shaped by a confluence of youth needs, institutional expectations, and other inputs. The quality of the setting is determined in part by practitioners' expertise in shaping and responding to these events. The situations that arise in practice, and how staff…

As shown by MetLife's 2010 "Survey of the American Teacher," America's educators strongly believe that all students should graduate from high school ready for college and a career (85 percent). Additionally, according to MetLife's 2009 survey, 86 percent of teachers believe that setting high expectations for students will improve student…

TIMSS (Trends in International Mathematics and Science Study) is an international assessment of mathematics and science at the fourth and eighth grades that has been conducted every four years since 1995, with the most recent assessment in 2011. PIRLS (Progress in International Reading Literacy Study) is an international assessment of reading…

This mixed-methods study explored the influence and applicability of the Perry Scheme to students from mainland China studying in the U.S. The purpose of this mixed methods study was to explore the intellectual and ethical development of students from mainland China enrolled in a U.S graduate engineering program using the Perry Scheme of…

In 1997, a statement was released from the 18th CARICOM Heads of Government Conference which, in effect, linked the economic development of the Caribbean region and its competitive advantage to the science and technological capabilities of its citizens. There are some serious implications of this statement for the continued economic growth and…

This Brief summarizes a study that addresses the impact of remedial and developmental courses on students with a range of levels of preparedness. Using longitudinal data from Tennessee, the authors estimate the effects of placement into varying levels of mathematics, reading, and writing courses for students attending public two- and four-year…

This is a conceptual paper, based on several semesters of collaboration in which the American author interacted with students in the Taiwanese author's EFL classes in Taiwan. The best native language users are typically those who read extensively, especially reading for pleasure in their youth. This gives them a large vocabulary and an intuitive…
