Preferences Of Students For The Hutchings "Low Stress" Compared To The Conventional Algorithm Under Conditions Of Differentially Increasing The Number Of Problems With And Without Reinforcement, Pamela G. Buitendorp Drew Dec 1980

Preferences Of Students For The Hutchings "Low Stress" Compared To The Conventional Algorithm Under Conditions Of Differentially Increasing The Number Of Problems With And Without Reinforcement, Pamela G. Buitendorp Drew

Masters Theses

This study was an attempt to determine which computation procedure students would select under varying classroom conditions. It is a systematic replication of previous research by Gillespie (1976). Algorithm preferences of 14 third grade students, 10 high accuracy and four low accuracy on a math facts test, were investigated under conditions of differentially increasing the number of problems with and without reinforcement, Reversal designs were used. The students completed 4X5 array problems and chose which algorithm to use, but after choosing the same algorithm for three consecutive sessions, they were required to use the alternative algorithm the next session. Preference …

A Limnological Investigation Of A Tropical Fresh-Water Ecosystem: The Belize River, Belize, Central America, Victor J. Gonzalez Aug 1980

A Limnological Investigation Of A Tropical Fresh-Water Ecosystem: The Belize River, Belize, Central America, Victor J. Gonzalez

Dissertations

The limnology of the Belize River, from the region of Spanish Lookout to the region of Belize City, was investigated from 1977 through 1979. The investigation was done primarily during the months of May through August, covering the two seasonal changes--wet and dry--that occur in this tropical region. The investigation sought to describe various parameters of the Belize River so as to gain an understanding of this tropical fresh-water ecosystem and to provide basic information needed for the development of management programs.

Water samples were collected from eight stations and analyzed for acidity, alkalinity, carbon dioxide, chloride, sodium chromate, hexavalent …
