Determining Return On Investment For Professional Development In Public Education: A Model, Michael F. Kosloski, Philip A. Reed Oct 2009

Determining Return On Investment For Professional Development In Public Education: A Model, Michael F. Kosloski, Philip A. Reed

STEMPS Faculty Publications

Return on investment with respect to employee training is a growing phenomenon in business and industry, as understanding the impact of training on an organization is often not enough. Public educational systems also spend a significant amount of resources on professional development. However, because education is a non-revenue generating industry, rarely do we analyze return on investment in the educational sector. This article examines return on investment for public school teacher training and professional development. While this model was developed for a specific school system and software, the model outlined below may be used by administrators in many non-profit or …


Enhancing The Collection Process For The Delphi Technique, Petros Katsioloudis, John Brocato (Ed.) Jan 2009

Enhancing The Collection Process For The Delphi Technique, Petros Katsioloudis, John Brocato (Ed.)

STEMPS Faculty Publications

The purpose of this manuscript is to describe a process that enhances the data collection process for a Delphi technique. The approach consists of online platforms to expedite the process and reinforce the validity of the Delphi technique. The context of the study was the identification of quality indicators for visual-based learning material development for Technology Education programs for grades 7-12.


Detection And Assessment Of Quality Indicators Of Visual Based Learning Material In Engineering Education Programs For Grades 7-12, Petros Katsioloudis Jan 2009

Detection And Assessment Of Quality Indicators Of Visual Based Learning Material In Engineering Education Programs For Grades 7-12, Petros Katsioloudis

STEMPS Faculty Publications

The purpose of this study was to detect the quality indicators of visual-based learning material in technology education for grades 7-12. A three-round modified Delphi method was used to answer the following research questions: RQ1: What indicators should quality visual-based learning material in technology education have to be effective and efficient in transmitting information for grades 7-12? RQ2: What are the indicators of the learner’s characteristics that impact the selection of visual-based learning material in technology education for grades 7-12?


Discovery Of The Depths, Petros J. Katsioloudis Jan 2009

Discovery Of The Depths, Petros J. Katsioloudis

STEMPS Faculty Publications

Throughout history the oceans have directly or indirectly influenced humans. The importance of knowing how to protect this valuable resource and insure it for future generations is vital. Underwater Vehicles are tools essential for this process, and therefore research and development to perfect these devices is needed. However, the main goal of these devices--to transmit images from places where humans cannot go--remains the same, and their importance to future discoveries remains vital. This article discusses the different types of underwater vehicles and describes an activity wherein students will fabricate an underwater remotely operated vehicle.


A New Generation Of Goals For Technology Education, John M. Ritz Jan 2009

A New Generation Of Goals For Technology Education, John M. Ritz

STEMPS Faculty Publications

[Introduction, First paragraph]

To develop meaningful instructional programs for technology education, goals need to be in place to direct the outcomes of curriculum development and teaching. Goals are program terminal outcomes that focus curriculum writers or teachers who structure content for learners. Goals provide direction so content can be delivered for long-term impact to students who study the subject. They go beyond everyday teaching objectives; they are directed at long-term learning and programmatic outcomes.


Energy From The Skies: Empowering Future Generations, Petros J. Katsioloudis, Stella Bondi, Walter F. Deal Jan 2009

Energy From The Skies: Empowering Future Generations, Petros J. Katsioloudis, Stella Bondi, Walter F. Deal

STEMPS Faculty Publications

The article discusses the development of photovoltaic technology. The first account of the use of solar power during war in western civilization was in the second century B.C. during the battle of Syracuse with Archimedes' famed Death Ray. In the late 1800s and early 1900s many advances occurred including the invention of solar-powered engines, the discovery of the photoconductivity of selenium and its ability to produce electricity when exposed to light, and the construction of the first solar cells from selenium wafers. Photovoltaic technology was born in the U.S. in 1954 when Daryl Chapin, Calvin Fuller, and Gerald Pearson developed …

According to the National Institute on Disability and Rehabilitation Research, an estimated 8.5 million children 21 years and younger have a disability (Jans & Stoddard, 1999). After about a decade, with the development of new and sophisticated materials (aluminum alloys, titanium alloys, and carbon fibers) and the integration of electronics, it was then possible to significantly improve the performance of prostheses, built with the so-called endo skeletal (or skeletal-modular) method (Mora, Beratni & Pedrotti, 2006).


Water Treatment: Keeping It Pure, Petros Katsioloudis Jan 2009

Water Treatment: Keeping It Pure, Petros Katsioloudis

STEMPS Faculty Publications

The article discusses the importance of water treatment in providing quality and safe drinking water. A historical background of the U.S. federal regulation of drinking water quality is presented. It was found by the Public Health Service in 1969 that only 60 percent of the systems surveyed delivered water that met all the Public Health Service standards. Filtration and chlorination are also cited as an effective treatment techniques for protecting U.S. water supplies from harmful microbes. An overview of the process of water treatment is presented.
