Environment-Based Education: Policy, Practice, And Place, Eric N. Wickwire Jan 2002

Environment-Based Education: Policy, Practice, And Place, Eric N. Wickwire

All Master's Theses

The policies of the environment-based education movement are benefiting teachers and students participating in several model programs operating in the United States. Place-centered learning enhances the interdisciplinary practice of Essential Academic Learning Requirements, and actively engages students in local issues. The study of cultural landscapes encourages a sense of place within the Lower Columbia River Gorge, and fosters student connections with the Dalles Mountain Ranch. Policy recommendations are made for environment-based learning in Washington State's public schools. An example place-centered curriculum is outlined for practice at the Dalles Mountain Ranch, and a residential environmental learning center is proposed in the …

Metastable States In Classical And Quantum Systems, Mark Makela, Samantha Parmley, Roger Yu Jul 1997

Metastable States In Classical And Quantum Systems, Mark Makela, Samantha Parmley, Roger Yu

All Faculty Scholarship for the College of the Sciences

The classical vibrational metastable states in a one-dimensional two-mass system are investigated experimentally and theoretically via the transmission of a coherent wave packet propagating through the system. The Fourier transform of the vibrational signal recorded in between the masses reveals resonant excitations by the coherent wave packet. The time-resolved spectrum indicates that the lifetime of a metastable state of higher frequency is longer than that of lower frequency, which is in contrast with the quantum mechanical double-barrier system. This study, which is easily accessible to physics majors, also demonstrates quantum resonant tunneling in a very simple classical way.

A Recycling Proposal For The Vashon Island School District, John Turner Green Jan 1990

A Recycling Proposal For The Vashon Island School District, John Turner Green

All Graduate Projects

The purpose of this study was to identify a process by which the Vashon Island School District could reduce its waste stream and involve and educate students in an environmental ethic that actively seeks to reduce and recycle wastes. A search of the general and educational literature was made. An extensive research of state and local agencies helped to identify appropriate goals and actions for the Vashon School District. The proposal calls for seven specific actions to be taken.

Transformational Geometry Unit, Elizabeth Ann O'Neill Jan 1980

Transformational Geometry Unit, Elizabeth Ann O'Neill

All Graduate Projects

The study included the development and writing of a unit on transformational geometry which involved a holistic approach including the cognitive, psychomotor, and affective domains. This unit was taught to the eighth grade class in the Oakville School District in Oakville, Washington. The results showed support that the teaching of this unit was effective.

A Comparative Investigation Of The Effects Of Frequent Testing Upon Achievement In Secondary Advanced Algebra, John Thomas Fullerton Aug 1971

A Comparative Investigation Of The Effects Of Frequent Testing Upon Achievement In Secondary Advanced Algebra, John Thomas Fullerton

All Master's Theses

Relatively speaking, few studies have concerned themselves with the problem of frequent testing, and as Keys pointed out, empirical evidence, uncomplicated by differences in the amount of testing material employed, on the effects of frequent testing is, at best, scarce (14:427). Also many studies used tests and test results for direct instruction, thus introducing additional variables. Furthermore, the choice of subjects and disciplines has been limited, the better part being taken from college psychology and sociology classes or high school science classes. This investigation was not an attempt to modify previous experiments, nor was it an attempt to identify which …

An Elementary Mathematics Curriculum Study To Determine If Achievement And Attitude Can Be Influenced By A Textbook Adoption, Elsie M. Railey Jan 1970

An Elementary Mathematics Curriculum Study To Determine If Achievement And Attitude Can Be Influenced By A Textbook Adoption, Elsie M. Railey

All Master's Theses

There is on the market a wide range of contemporary mathematics textbooks available. Textbooks approach mathematics differently and there is a variation in terms of the amount of time allocated to a topic, the development of elementary concepts and laws of arithmetic, and the amount of drill and repetition. The sequential development of the texts follows closely, but the scope and content differ significantly. Specifically, it is the purpose of this study to determine if there is a significant difference between series, as opposed to those in another mathematics series, in the variables of attitude and achievement. The two textbooks …

On The Theory Of Quaternions, Earle David Smith Aug 1969

On The Theory Of Quaternions, Earle David Smith

All Master's Theses

Ordered triplets serve to describe space geometrically just as ordered pairs serve to describe the plane. A multiplication can be defined on pairs consistent with the complex numbers. However, as this paper will show, one cannot define a multiplication on triplets which is consistent with the complex numbers.

Glycosidic Enzymes Of The Tropaeolum Majus, Donald Richard Snowden Jun 1969

Glycosidic Enzymes Of The Tropaeolum Majus, Donald Richard Snowden

All Master's Theses

The purpose of this study is to investigate the hydrolytic enzymes of Tropaeolum majus. This particular plant is the only example of the Tropaeolum genus found in the northern hemisphere. It is the well-known Indian cress or common garden nasturtium.
