Semi-automatic control system for hydraulic shovel
A semi-automatic control system for a hydraulic shovel has been developed. Using this system, unskilled operators can operate a hydraulic shovel easily and accurately. A mathematical control model of a hydraulic shovel with a controller was constructed and a control algorithm was developed by simulation. This algorithm was applied to a hydraulic shovel and its effectiveness was evaluated. High control accuracy and high-stability performance were achieved by feedback plus feedforward control, non
What is Matter?
Our understanding of atoms has been formed through decades of experimentation. In this activity, students learn about the historical developments of atomic theory while labeling the new discoveries.

Our Lives Were Healthier Before: Focus Groups With African American, American Indian, Hispanic/Latin
Focus groups were conducted to explore health-related beliefs and experiences of African American, Hispanic/ Latino, American Indian, and Hmong people with diabetes and engage community members in improving diabetes care and education for these populations. Eighty participants attended 12 focus groups, 3 per population. Major themes were loss of health attributed to modern American lifestyles, lack of confidence in the medical system, and the importance of spirituality. Participants recommended
Measuring Health Disparities
Measuring Health Disparities is designed to be accessible to a broad audience of practitioners across all sectors of the public health workforce. In contains audio and interactive elements and focuses on some basic issues for public health practice - how to understand, define, and measure health disparity. The material is divided into four parts. Parts One and Two review what health disparities are, how they are defined, and provide and overview of common issues faced in measuring health dispar
This applet covers an aspect of the Physical Chemistry II course that students often find confusing. Although it is based on relatively simple mathematics, a complete understanding of the phenomenon requires assimilating the following concepts: The energy levels of a diatomic molecule are given by the formula: E(v,J) = hv (v + ½) + BJ (J + 1); v = 0..infinity, J=0..infinity. A molecule absorbs light at frequencies that correspond to difference between energy levels. In this case, we are interes
Water Uses and Children's Lives in East Africa
asks students to compare their interactions with water to those of children in Kenya and Tanzania and discover that access to water helps to define children's roles in the family. They can then demonstrate their understanding through essays and pictures.
A learning object is best described as a representation designed to be reused in different educational contexts. In this page you will references to my papers and examples of various learning objects develop either by my self or by my students. Learning objects might reside in digital repositories, ready to be located and utilized by those involved in educational activities (e.g., teachers and students). They address: (a) key concepts from disciplines, in visual and often interactive ways not pe
Active Lessons are engaging, technology-based, student-centered (pupil-centered) learning activities designed by teachers using PowerPoint (or other presentation tool). The idea is to empower teachers to easily create technology-based activities that draw upon variety of existing and new digital resources from internet, repositories of learning objects and other sources, and require students to use technology and create artifacts demonstrating their understanding. This idea partially challenges
Calculate the Top Quark Mass
Students use conservation of momentum to calculate the mass of the top quark. This activity examines the fingerprint of a top/antitop production that took place in the D-Zero Detector at Fermilab on July 9, 1995. This activity will build on student understanding of vector addition and depends upon only a small amount of particle physics explanation.
Investigating Special Relativity with Particle Physics Data
This Website provides resources for secondary and post-secondary teachers of physical science. These resources include data reduction projects and particle physics datafiles. The data reduction projects guide student investigation of a dataset to a particular end result. The datafiles are written in a format that allows for rapid Web file transfer and ease of import into commonly available applications such as Microsoft Excel. Students download and reduce these data in an open-ended environment
Decays Let Physicists Look Inside Particles
These pages invite students to test various particles for their decay products. Most particles studied by physicists are unstable; they decay. That is, given enough time by itself, one unstable particle will fly apart into two or more particles. By carefully observing and logically classifying these decays according to some well-understood laws of nature, particle physicists have been able to explain much about the fundamental structure of matter.
Environmental Landfill Management
Lesson objectives: Students will be able to identify what a pollutant is and its affects on the environment. The students will demonstrate knowledge of the vocabulary used in environmental management by the DOE and other federal agencies. The students will attain a basic understanding of waste problems within our environment and the fundamental concepts of the laws of nature, science, physics, and engineering. Students will construct and operate a small-scale leach-bed barrier system.
Strategic Planning for Electronic Governance
This course aims to provide a basic understanding of e-governance strategies and teaches how an effective strategic plan can be developed through a process. Important elements of the strategic plans of some e-governance leaders are also discussed as case studies.
Medicine III: Hospital Clerkship Program
This course gives the dental student not only an understanding of the complexity of issues associated with the medically compromised patient but the ability to comfortably manage such patients in the dental setting as well.
Listening to Music
This course fosters the development of aural skills that lead to an understanding of Western music. The musical novice is introduced to the ways in which music is put together and is taught how to listen to a wide variety of musical styles, from Bach and Mozart, to Gregorian chant, to the blues.
LIT 331: World Literature II: Africa and the Middle East, Asia, and Europe
Literature 331 offers students an opportunity to enhance their understanding of contemporary global interactions by exploring a diverse array of culturally expressive artifacts---novels, short stories, and poems--grouped geographically by region. Course readings represent the following regions: Europe, Asia, and Africa and the Middle East. A second course, Literature 330, covers the literature of North America, Latin America and the Caribbean, and Australia and Oceania.
Essential Science for Teachers: Physical Science. Session 1. What Is Matter?: Properties and Classif
Matter is all around us,its what we and everything else are made of. Yet how do we define matter? What are the properties of matter that set it apart from something that is definitely not matter such as light? In this session, well build a working definition of matter, and distinguish between the different forms that it can take. Well also sort out the difference between essential and accidental properties of matter, and look at the role of classification in science,Students inv
Historical Thinking Matters
For too many Americans, the history class in Ferris Bueller’s Day Off (remember the teacher’s plaintive question, “anyone, anyone?”) is all too familiar. Our approach is meant to challenge this false and familiar image of history: understanding and reconstructing the past requires ways of thinking, reading, and questioning much more engaging and challenging than mere memorization. Teaching in a way that differs from your own schooling experience is not necessarily easy to imagine, let a
Essential Science for Teachers: Life Science: Session 2. Classifying Living Things
How can we make sense of the living world? During this session, a systematic approach to biological classification is introduced as a starting point for understanding the nature of the remarkable diversity of life on Earth.,This segment has students talking about the gas requirement of all living things. They have a notion about oxygen and carbon dioxide.
