The purpose of this qualitative study was to identify feedback strategies utilized by high school teachers in the classroom setting, how they used that feedback to affect subsequent instruction, and the teachers' perceptions of their use of feedback and student understanding. The data were collected from interviews with 6 high school teachers and…

Learn assessment strategies that provide you with a real representation of student progress--without the need for excessive tests. In "Test Less, Assess More: A K-8 Guide to Formative Assessment", authors Leighangela Brady and Lisa McColl show you how to turn daily classroom lessons and activities into valuable opportunities for assessment,…

Clustering is one of the most common data mining tasks, used frequently for data organization and analysis in various application domains. Traditional machine learning approaches to clustering are fully automated and unsupervised where class labels are unknown a priori. In real application domains, however, some "weak" form of side…

This discussion paper compares and contrasts "inductive" and "deductive" research approaches as described by Trochim (2006) and Plano Clark and Creswell (2007). It also examines the "exploratory" and "confirmatory" approaches by Onwueghuzie and Leech (2005) with respect to the assumption each holds about the nature of knowledge. The paper starts…

A piezoelectric material generates an electric potential across its surface when subjected to mechanical stress; conversely, the inverse piezoelectric effect describes the expansion or contraction of the material when subjected to some applied voltage. Piezoelectric materials are used in devices such as doorbell buzzers, barbeque igniters, and…

This article focuses on school self-evaluations (SSE). It addresses whether SSE meets quality indicators and whether differences can be found between the quality judgments of school principals and inspectors. Data stem from two complementary data collections: population data of school inspections and a survey of a representative sample of school…

Nuclear magnetic resonance (NMR) poses significant challenges for teaching in the context of an undergraduate laboratory, foremost because of high equipment cost. Current off-the-shelf data-acquisition hardware, however, is sufficiently powerful to constitute the core of a fully digital NMR spectrometer operating at the earth's field. We present…

The purpose of this qualitative case study research was to explore faculty-based academics' views on what influences their behaviours and attitudes towards their development. Informed by critical realist ontology, the data collection was carried out through narrative interviews with academics in two contrasting English universities. Findings, or…

The purpose of this series of experiments was to evaluate the effects of mixed mand-tact arrangements on the acquisition of mands and tacts in preschool-aged children. In Experiment 1, the effects of three training arrangements (mand-only training, tact-only training, and mand-tact training) were investigated with 3 typically developing children.…

"Focus on opportunities" is a cognitive-motivational facet of occupational future time perspective that describes how many new goals, options, and possibilities individuals expect to have in their personal work-related futures. This study examined focus on opportunities as a mediator of the relationships between age and work performance and…

This article details the construction of a computer program to test cognitive processing differences in adolescents engaged in a standard presentation of tests versus a fantasy-based game presentation. The article will discuss the challenges of creating a replication of traditional psychological tests into a new medium which holds comparable…

The fact that humans possess fast and slow-twitch muscle in the ratio of approximately 50% has profound implications for designing exercise training strategies for power and endurance activities. With the growth of exercise and sport science courses, we have seen the need to develop an undergraduate student laboratory that demonstrates the basic…

Oranges, flying disks, pool noodles, and polyvinyl chloride (PVC) pipe may seem like items discarded after a Rube Goldberg experiment, but in fact, these objects were used in teaching science, technology, engineering, and math (STEM). This article describes a project in which The Center of Ocean Sciences Education Excellence SouthEast (COSEE SE)…

This investigation provides detailed descriptions of preservice secondary science teachers' technology-enhanced inquiry instruction and their developing TPACK. Prior to student teaching, 27 preservice teachers were introduced to general guidelines for integrating technology to support reform-based science instruction. This instruction was in…

Many public schools are experiencing improved student, staff, and school outcomes with the adoption of a positive behavioral interventions and supports (PBIS) framework, which organizes evidence-based practices into an integrated continuum of supports. Although alternative programs are often more restrictive and specialized because of the…
