I Can’t Take the Pressure!
Students develop an understanding of air pressure by using candy or cookie wafers to model how it changes with altitude, by comparing its magnitude to gravitational force per unit area, and by observing its magnitude with an aluminum can crushing experiment.
What’s Hiding in the Air?
Students develop an understanding of the effects of invisible air pollutants with a rubber band and hanger air test and a bean plant experiment. They also learn about methods of reducing invisible air pollutants.
For Your Eyes Only
Students develop their understanding of visible air pollutants with an incomplete combustion demonstration, a “smog in a jar” demonstration, and by building simple particulate matter collectors.
Air - Is It Really There?
By watching and performing several simple experiments, students develop an understanding of the properties of air: it has mass, it takes up space, it can move, it exerts pressure, it can do work.
A Recipe for Air
Why do we care about air? Breathe in, breathe out, breathe in... most, if not all, humans do this automatically. Do we really know what is in the air we breathe? In this activity, students use M&Ms® to create a pie graph that expresses their understanding of the composition of air. The students discuss why knowing this information is important to engineers and how they use this information to improve technology to improve our planet.
Applying Hooke's Law to Cancer Detection
In this activity, students will explore Hooke’s Law in small groups at their lab bench. They will collect displacement data for a spring with an unknown spring constant, k, by adding various masses of known weight. After exploring Hooke’s law and answering a series of application questions, students are asked to apply their understanding to explore a tissue of known surface area. Students will then use the necessary relationships to depict a cancerous tumor amidst normal tissue by creating a
Detecting Breast Cancer
This lesson introduces students to their task of developing a painless means of identifying cancerous tumors. Solving the challenge will depend on an understanding of the properties of stress and strain. After being introduced to the challenge question, students will generate ideas and consider the knowledge required to solve the challenge question. After which, students will read an expert’s opinion on ultrasound imaging and the potentials for detecting cancerous tumors. This interview will h
Solid State Physics
In the electrical engineering, solid-state materials and the properties play an essential role. A thorough understanding of the physics of metals, insulators and semiconductor materials is essential for designing new electronic devices and circuits. After short introduction of the IC fabrication process, the course starts with the crystallography. This will be followed by the basic principle of the quantum mechanics, the sold-state physics, band-structure and the relation with electrical propert
Reducing Racial/Ethnic Disparities in Female Breast Cancer: Screening Rates and Stage at Diagnosis
Objectives. We assessed whether population rates of mammography screening, and their changes over time, were associated with improvements in breast cancer stage at diagnosis and whether the strength of this association varied by race/ethnicity. Methods. We analyzed state cancer registry data linked to socioeconomic characteristics of patients’ areas of residence for 1990–1998 time trends in the likelihood of early stage diagnosis. We appended each cancer registry record with matching subgro
1940s House: Making a Connection between WWII and Rationing
Through viewing and discussion of the video and investigation of the Web resources, students will develop a deeper understanding of rationing and the mathematics needed in a WWII household.

Mother and Teacher Interaction in Preschools during Parent-Teacher Conferences
The education of children has been a long-standing issue for stakeholders over numerous years. Various literatures recommend that formal learning should begin during the preschool years of a child’s life, and must include home-school partnerships. Empirical data has shown that parents and teachers who work together can positively impact a child’s success in school. This study sought to gain insight into the phenomenon of parent-teacher interactions in preschools, via the lens of symbolic int
The Impact of Retention on Student Educational Outcomes: A Five Year Study of a Group of Retained an
Accountability has become a major focus in educational reform and an increasing number of states and school districts are adopting policies to end social promotion. These policies generally include mandatory retention for students who fail to meet cut-off scores on high-stakes tests. Despite compelling evidence to the contrary, educators believe that underachieving students need, or deserve, to be retained and will benefit from repeating a grade. Using archival data from a large urban school dis
The United States Postal Service: A Case Study of Large Scale Government Transformation
The challenge of replacing the baby-boomer generation of employees is beginning in government agencies as they face a “tsunami” of retirements. This generation forms the core of middle managers or supervisors who are essential to providing the continuity in government organizations that serve the needs of citizens on a daily basis, or most critically in times of crisis. This same generation of government employees worked through decades of change in public administration. The 1980s privat
A Study of a Specific Language Arts and Mathematics Software Program: Is There a Correlation Between
The purpose of this study was to compare usage levels of CompassLearning Odyssey mathematics and language arts software among fifth grade students in order to determine the relationship between usage and achievement. While educational software designed by various companies is a regular part of daily instruction in most public schools across the United States, there remains a need for research-based evidence of the efficacy of specific programs. This study used a quantitative design to compare ac
EMBODYING RESEARCH: A STUDY OF STUDENT ENGAGEMENT IN RESEARCH WRITING
College students often perceive the university as alienating; reading and writing impersonal research texts can intensify this sense of disconnect. College professors often feel passion and enthusiasm toward their own research yet find it difficult to create this excitement in their research writing classrooms. This qualitative study explored student and teacher perceptions and instructional approaches in a university research writing course, seeking clues to student engagement. Data collecti
Structural Awareness for Collaborative Learning Environments
In this paper we propose a peer-to-peer support approach that we call structural awareness support. The structural awareness aims to support the communication that takes place in virtual learning communities. Its emphasis is on revealing the group structure to its participants in order to promote collaborative interactions. This support has been implemented on a forum type tool called Mailgroup. It has been tested twice in different contexts, obtaining initial feedback of its pertinence accordin
University / K – 12 Partnerships: How One University Impacted High School Career Decision-making
Local universities and their surrounding school districts have much to offer one another. How universities and school districts work together to create programmatic change in career decision-making for the high school adolescent is unclear. Utilizing a case study approach, this study examined the relationship that exists between a university and two high schools. This was studied through the lens of career development with regard to high school students. This qualitative case study utilized pe
Possible Predictive Factors for the Greater Johnstown School District’s Pennsylvania System of Sc
Relative to Curriculum-Based Assessment (CBA) and the Pennsylvania System of School Assessment (PSSA), this study sought to determine whether a school district’s CBA reading scores were predictors for the PSSA reading scores for a grade-level cohort of students. Those CBA reading scores were collected in fourth through seventh grades; while the PSSA measure was a scaled score earned on the eighth grade reading measure. The sample included 268 eighth grade students who were roughly 48% male,
The Role of the Elementary Principal in Promoting Parent Involvement: Evidence from Rural, Blue Ribb
The reauthorization of the Elementary and Secondary School Education Act has amplified the implications of including parents in the education process. The benefits of parental involvement coupled with the teachers' and parents’ role in promoting involvement have been researched and studied for many years. Few studies focus solely on the principal’s role in promoting parent involvement, however. This study will examine the specialized association and participation of rural elementary princ
