A laboratory experiment reinforces the concept of acid-base equilibria while introducing a common application of spectrophotometry and can easily be completed within a standard four-hour laboratory period. It provides students with an opportunity to use advanced data analysis techniques like data smoothing and spectral deconvolution to…

In 2010-11, the Literacy Design Collaborative (LDC) framework was piloted in six districts, a teacher network, and a network of schools. In most cases, school districts applied for and received grants to implement LDC; in others, regional intermediaries served as the grantee and as primary organizer of the work; and, in still others, national…

With teacher shortages in both general and critical needs areas and constricting operating budgets, it is important for Colleges of Education to develop methods of providing alternative certification programs to reach larger segments of the population. One method of increasing the scope of potential preservice teachers is through the development…

Previous research indicates that the principal is second to the teacher in their impact on student learning. However, oftentimes principals enter their position lacking the skills and knowledge of an effective instructional leader. Moreover, districts may lack the internal capacity to support principal's professional development and learning. If…

An invitation to explore innovative practices in program and system evaluation in a medium-sized school jurisdiction of approximately 11,000 students has resulted in a model with generative characteristics. This paper will describe the process, and several of the outcomes, when a generative evaluation approach is used to assess the effectiveness…

A Monte Carlo study examined the statistical performance of single sample and bootstrap methods that can be used to test and form confidence interval estimates of indirect effects in two cluster randomized experimental designs. The designs were similar in that they featured random assignment of clusters to one of two treatment conditions and…

Recently, nonparametric methods have been proposed that provide a dimensionally based description of test structure for tests with dichotomous items. Because such methods are based on different notions of dimensionality than are assumed when using a psychometric model, it remains unclear whether these procedures might lead to a different…

In the context of reviewing an article for this journal (van der Linden & Sotaridona, this issue, pp. 283-304) the topic of unconditional and conditional hypothesis testing came under consideration. While this is hardly a new issue (consider, for example, arguments regarding the chi square vs. Fisher exact test of independence for a 2 x 2…

The authors propose new procedures for evaluating direct, indirect, and total effects in multilevel models when all relevant variables are measured at Level 1 and all effects are random. Formulas are provided for the mean and variance of the indirect and total effects and for the sampling variances of the average indirect and total effects.…

It is widely accepted that mathematical skills are critically important in our technologically sophisticated world. Educators' metacognition directs, plans, monitors, evaluates and reflects their instructional behaviour and this can promote learners' learning with understanding. The purpose of this study was to investigate the extent to which…

The Texas Education Agency's Social Studies Texas Assessment of Knowledge and Skills results show an achievement gap between males and females for every criteria on every test given since 2003. The most dramatic achievement difference is in the area of "traditional" U.S. History. The Texas results mimic a gender gap reported by College…

As engineers contribute to solving the increasingly complex problems facing our society, there is a growing need for the engineers graduating from undergraduate programs to deeply understand the context within which they are solving problems. There is a particular need for engineers who recognize the complexities of global and societal issues and…

This study examined the relative benefit of three interventions (i.e. physiological, behavioural, and pragmatic) designed to facilitate speech recognition software use. Participants were 15 adults with dysarthria associated with a variety of aetiological conditions, including cerebral palsy, Parkinson's disease, and motor neuron disease. Results…

The authors examine an institutional assessment model for general education that effectively incorporates instructor-driven strategies. This article is informed by the perspectives of a teaching librarian and a departmental faculty member at the University at Albany, State University of New York. As instructors, they both participated in mandated…

Background: Students are unable to benefit from many school programs designed to address their mental health needs if their parents do not consent to their participation. As part of an ongoing effort in a large urban school district to meet the mental health needs of students traumatized by violence exposure, this paper examines the impact of…
