During the last decade, global optimization has attracted a lot of attention due to the increased practical need for obtaining global solutions and the success in solving many global optimization problems that were previously considered intractable. In general, the central question of global optimization is to find an optimal solution to a given…

Client-centered and consultee-centered consultation models are predominately used in K-12 schools to meet the needs of at-risk learners and ensure equitable access to educational services. Although the efficacy of both models has significant support in the literature, studies regarding relationships formed during problem solving in consultation…

In order to address some of the challenges facing engineering education, namely the demand that students be better prepared to practice professional as well as technical skills, we have developed an intervention consisting of equipment, assessments and a novel pedagogy. The equipment consists of desktop-scale replicas of common industrial…

The purpose of this study was to examine the effectiveness of a mathematics problem solving intervention strategies for 3rd grade students identified as having a Mathematics Disability and students who are English Learners. The intervention targeted specific proposition within word problems as a means to enhance solution accuracy. Three…

A review of the nursing literature reveals many undergraduate nursing students lack proficiency with basic mathematical skills, those necessary for safe medication preparation and administration. Few studies exploring the phenomenon from the undergraduate nursing student perspective are reported in the nursing literature. The purpose of this study…

This is a comprehensive study of the many facets of an entirely online organic chemistry course. Online homework with structure-drawing capabilities was found to be more effective than written homework. Online lecture was found to be just as effective as in-person lecture, and students prefer an online lecture format with shorter Webcasts. Online…

Students with specific learning disabilities (SLD) tend to have difficulty with reasoning and communication across many mathematical domains. The purpose of this study was, through open response questions, to examine the mathematics reasoning performance of 4 th grade students with SLD. Using the learner centered principles outlined by the…

The primary concern in current interaction design is focused on how to help users solve problems and achieve goals more easily and efficiently. While users' sufficient knowledge acquisition of operating a product or system is considered important, their acquisition of problem-solving knowledge in the task domain has largely been disregarded. As a…

\The purpose of this study was to investigate population invariance of the true-score linking functions with respect to the ability subgroups (i.e., average-achieving students, low-achieving students, and students with learning disabilities). The mean/mean linking functions for five alternate forms of a curriculum-based math problem solving…

In this study, the effectiveness of worked examples that emphasizes problem features (data type, number of groups, purpose of analysis) associated with specific problem types (t-test, chi-square, correlation) were examined on students' construction of problem schemata compared to traditional solution-only worked examples. A sample of 96 students…

This research explores how chief cabin crew members of major airlines made their decisions on-the-spot when they had unexpected problems. This research also presents some insights that may improve personnel training programs for future stewardesses and stewards based on the investigation of their decision-making styles. The theoretical framework…

Computer technology is used as a mediational tool to support collaborative instructional methods. Computer support offers a platform for collaboration with the goal of scaffolding students' understanding, providing increased agency to the student for their own learning, and motivating students, as participants in a PBL process. In online PBL,…

Teacher shortages are a critical issue for education, and agricultural education has not been exempt from this trend. Many factors possibly contribute to this lack of qualified teachers. Researchers suggest that retention practices, stress factors associated with agricultural education, and job satisfaction may be areas for improvement within the…

In this study, I investigated how proficiently seventh-grade students enrolled in two Southwestern schools solve algebra word problems. I analyzed various factors that could affect this proficiency and explored the differences between English Learners (ELs) and native English Primary students (EPs). I collected the data as part of the Animal Watch…

People in the United States live in an era of heightened fear of sexual offenders. The general public, especially women, fear sexual assault and for the safety of their children. Federal and state legislation has established stringent sexual offender notification and registration, and residency restriction laws to protect citizens in communities.…
