Project-Based High School Science Activities

The development of project-based science activities and assessment rubrics are presented. A total of fifteen different science projects are presented for use in the high school science classroom. The activities are complete with lesson plans, design lessons, overviews of materials and follow up assessments. The activities are designed to combine essential academic learning requirements with real-world applications and can be applicable to a wide variety of concepts. The development of these activities is supported by the literature review as well as the use in the author\u27s classroom

The rate of release of potassium from some Tennessee soils

The purpose of this study is to determine the rate of release of non-exchangeable to exchangeable potassium in different Tennessee soils

The quality school in postsecondary education

In the past, Reality Therapy seminars and workshops were presented by professionals who were skilled in their field, but had only limited training in adult education, including curriculum and instruction. By utilizing materials and information received in the U.N.L.V. graduate Post Secondary Education program in conjunction with Dr. William Glasser\u27s Quality School concepts, the Reality Therapy training can be redesigned to deliver more effective education. There will be an extensive review of information from the graduate program, Dr. Glasser\u27s books and articles, plus the resources of the U.N.L.V. library. New materials developed will be class activities and lesson plans that will include unit and enabling objectives, anticipating set, input, modeling, monitoring, guided practice, independent practice, motivation and closure that will result from a task analysis. Two workshops will be conducted using these methods. There will be student evaluations and instructor observations to support the summary, followed by the writer\u27s reflections.

A Grammatical Sketch of Comox

Thesis (Ph. D.)--University of Kansas, Linguistics, 1981. Data was gathered in two summers of fieldwork, 1970 and 1971, at the Comox Reserve in British Columbia.Comox is a Salish language spoken on both sides of the Gulf of Georgia on the west coast of British Columbia, Canada. Before white contact, it was spoken on Vancouver Island from the Salmon River in the north to the present day town of Comox in the south. It was also spoken on Quadra Island and other islands in the Strait and at sites on the mainland. It presently exists in two distinct dialects whose most striking difference is an s-theta correspondence and an aveolar-interdental affricate correspondence. The mainland dialect is spoken at three sites by about 500 people. The island dialect is spoken by two people at a reserve near the town of Comox half way up the east coast of Vancouver Island. The phonology of the mainland dialect was described in a master's thesis by John Davis at the University of Victoria, 1970. The only published description of island Comox is an article by Sapir on noun reduplication. Since the island dialect is about to die out and has not been extensively studied, this dissertation attempts it description before the dialect is lost. The data used were gathered in two summers of fieldwork in 1970 and 1971 at the Comox Reserve. The data presented in Sapir's article are also used as well as some data gathered by Boas in 1889 and presently in the Smithsonian Institution. The syntactic model of analysis is a transformational case grammer and the phonology, a generative model using the features of Chomsky and Halle. After a brief discussion of the model of analysis and the data available, an overview of the cultural and linguistic context of Comox is presented. The material for this overview is taken from secondary sources and does not represent original work. The majority of the dissertation is taken up with an exposition of the syntax and phonology of the language. Syntactically Comox is a VSO language. The order of cases following the verb is: Agent Dative Benefactive Object Instrument Locative and Time. Agreement transformations add suffixes to the predicate corresponding to the first two cases present. There are three object suffix paradigms: (1) a transitive, (2) a detransitive which indicates the agent caused the object to do the predicate. "He made me dig," where "dig" is the verb, "he" the subject and "me" the object. And finally (3) the unintentional transitive object. The three subject suffix paradigms are: (1) the intransitive, (2) the transitive and (3) the embedded. There are three tenses (present, past and future) and five aspects (perfect, imperfect, stative, inceptive and continuative). Nominals are reduplicated for the plural and diminutive as are verbal stems for the imperfect. A set of phrase structure rules is formulated and possible transformations discussed. The phonology consists of thirty-eight rules, seven of which are precyclic. Three of the pre-cyclic rules are spelling rules for reduplication. Among the more unusual phonological rules is the metathesis of glottal stops and resonants. Underlying "y" and "w" become "j" and "g" respectively. Nasals become voiced stops under circumstances that are not completely clear. The underlying segment inventory includes glottalized resonants, stops, and affricates. There are five vowels. Aspects of the historical development of Comox are discussed briefly in connection with various features of the syntax and phonology

Fluid Velocity Fluctuations in a Suspension of Swimming Protists

In dilute suspensions of swimming microorganisms the local fluid velocity is a random superposition of the flow fields set up by the individual organisms, which in turn have multipole contributions decaying as inverse powers of distance from the organism. Here we show that the conditions under which the central limit theorem guarantees a Gaussian probability distribution function of velocities are satisfied when the leading force singularity is a Stokeslet, but are not when it is any higher multipole. These results are confirmed by numerical studies and by experiments on suspensions of the alga Volvox carteri, which show that deviations from Gaussianity arise from near-field effects.Comment: 4 pages, 3 figure

Usefulness of heart measures in flight simulation

The results of three studies performed at the NASA Langley Research Center are presented to indicate the areas in which heart measures are useful for detecting differences in the workload state of subjects. Tasks that involve the arousal of the sympathetic nervous system, such as landing approaches, were excellent candidates for the use of average heart-rate and/or the increase in heart-rate during a task. The latter of these two measures was the better parameter because it removed the effects of diurnal variations in heart-rate and some of the intersubject variability. Tasks which differ in the amount of mental resources required are excellent candidates for heart-rate variability measures. Heart-rate variability measures based upon power spectral density techniques were responsive to the changing task demands of landing approach tasks, approach guidance options, and 2 versus 20 second interstimulus-intervals of a monitoring task. Heart-rate variability measures were especially sensitive to time-on-task when the task was characterized by minimal novelty, complexity, and uncertainty (i.e., heart-rate variability increases as a function of the subjects boredom)

Duality of the Weak Parallelogram Laws on Banach Spaces

This paper explores a family of weak parallelogram laws for Banach spaces. Some basic properties of such spaces are obtained. The main result is that a Banach space satisfies a lower weak parallelogram law if and only if its dual satisfies an upper weak parallelogram law, and vice versa. Connections are established between the weak parallelogram laws and the following: subspaces, quotient spaces, Cartesian products, and the Rademacher type and co-type properties
