This work shows the redesign of an elemental experience based on the Helmholtz resonator using 3D printing. A Helmholtz resonator is based on a volume and at least one opening that can include a tube or not. The air column inside the tube can be considered the mass of the system, whereas the volume represents the system's stiffness. Due to these…

Toxic Release Inventory facilities are among the many environmental hazards shown to create environmental inequities in the United States. This project examined four factors associated with Toxic Release Inventory, specifically, manufacturing facility location at multiple spatial scales using spatial analysis techniques (i.e., O-ring statistic and…

Early childhood educators in the United States and worldwide face the growing challenge of "schoolification,"--the imposition of conventional academic content from later grade levels into their classrooms (e.g., Ring & O'Sullivan, 2018). The science of learning offers a different approach with evidence to support more active,…

Demonstrates how the tragedy of the 1986 space shuttle "Challenger" provides an example of how communication through memos and letters concerning O-ring problems went awry. Presents some methods by which the technical writing teacher might incorporate this material into their writing curricula. (HB)

The Skills Assessment Module (SAM) is designed to assess special needs students' affective, cognitive, and manipulative strengths and weaknesses in relation to vocational skills required in various training programs within a school system. Initial sections outline procedures and techniques (including paper-pencil tests, hands-on skill modules and…

In recent years there have been significant changes in education across the globe, largely as a result of changing demographics, technological developments, and increased globalization. Relatedly, the changing needs of societies and families, along with new research findings, provide new directions in early childhood education. Consequently, early…

The Prevocational Assessment Screen (PAS) is designed to provide instructors or evaluators with a quick (50 minutes to score and administer) and simple (requiring no training to administer) method of screening mildly handicapped and disadvantaged youth between 14 and 21 years of age for job training and placement. PAS contains eight samples which…

This guide is designed to assist industrial vocational instructors in teaching a course on fluid power and basic hydraulics. Covered in the unit on the basics of fluid power and hydraulics are the following topics: the fundamentals of fluid power and hydraulics, basic hydraulic circuits, and servicing a hydraulic jack. The second unit, consisting…

This guide is intended to assist vocational agriculture teachers who are teaching secondary- or postsecondary-level courses in agricultural power and machinery. The materials presented are based on the Arizona validated occupational competencies and tasks for the following occupations: service manager, shop foreman, service technician, and tractor…

This manual on bearings and seals is one of a series of power mechanics texts and visual aids for use in training for the servicing of automotive and off-the-road farm and industrial machines. Materials provide basic information and illustrations for use by vocational students and teachers as well as shop servicemen and laymen. Focusing on…

Child development "laboratory schools are dedicated to research-based instruction and furthering innovation in education. Many of these schools are connected to universities, where students are able to benefit from university resources and best practices" (Khan, 2014). They have been in existence on university campuses for centuries in…

By teaching about and considering the elements of visual design, communication can be effected and the needs of the reader/user more effectively met. As anecdotal interaction with children indicates, information seems to be communicated more effectively when the rhetor incorporates visual elements. To increase the ability of the reader to…

An operationally straightforward, project-like laboratory experiment has been developed in which students directly compare the reactivity of two heterocycles, a cyclic "O,O"-acetal (standard C-O protecting group) and a cyclic "N,O"-acetal (oxazolidine), toward sodium borohydride and methylmagnesium iodide. Students synthesize a…

Students in the United States are not achieving in mathematics as indicated on the NAEP (2019) exams and other measurements of student achievement (NCES, 2019; OECD, 2019; O'Dwyer, et al., 2015). Mathematically gifted and promising students are especially impacted by this phenomenon, though it is not exactly known what factors contribute to…

A discovery-based undergraduate organic chemistry lab experiment has been developed in which students establish the diastereoselectivity of hydride reduction of the a-chiral ketone (±)-benzoin isopropyl ether to erythro and threo diastereomeric alcohols by two different reducing agents. Students achieve this goal by working collaboratively and…
