This investigation was designed to investigate the use of an answer-until-correct procedure on multiple-choice quizzes in an independent study mathematics course. This procedure was compared to the standard multiple-choice procedure with respect to student achievement, student anxiety, and test reliability. Using the answer-until-correct procedure students were made immediately aware of...
This investigation was designed to determine the general achievement,
ability to solve applied problems, and attitude toward the role of
mathematics in science of college calculus students grouped in an
experimental class according to academic major during their first
three terms. The subgroups were biology-business, mathematics,
and science-engineering majors. The...
The theory of characteristics is discussed and its scope has
been broadened by its application to the most general form of an unsteady,
two-dimensional, compres sible, rotational, axial- symmetric
fluid flow. Numerical procedure for solving such a problem is outlined.
Several boundary conditions which are common in fluid flow
problems...
An experimental study was made of the average and turbulent
wind characteristics of the flow over a model of a coastal headland.
The scale of the model was 300:1, corresponding to a prototype size
of 500 m.
The data for validation of the model study was obtained from
instruments mounted...
This investigation was designed to determine the effectiveness
of video-tape feedback as a technique to modify some selected behaviors
of untrained prospective elementary teachers. Four verbal
and four nonverbal behaviors were considered; they were: teacher
questioning, teacher telling, teacher distractive verbal, teacher
allowing for pupil verbal, teacher constructive nonverbal, teacher...
The purpose of this study was to analyze the effect of the use
of vocationally - oriented applications on the achievement and attitude
of community college beginning algebra students. The applications
were chosen to be representative of problems encountered in
a variety of occupations. They were in contrast to the...
Development of a performance analysis for propeller type wind
turbines is presented. The analysis uses a strip theory approach
that includes tip-loss and blade interference. A comparison is
presented between analysis and test data. The comparison indicates
that the analysis predicts wind turbine performance to an accuracy
that is within...
This investigation was designed to determine whether a remediation
program concurrent to enrollment in the Calculus could be used
to reveal and remedy student deficiencies involving pre-calculus topics,
promoting a greater degree of success in the Calculus. The instructional
model for the program that was investigated consisted of pretesting
the...
