CONSTRUCTION AND IMPLEMENTATION OF A VISIBLE RANGE SPECTROPHOTOMETER FOR HIGH SCHOOL CHEMISTRY
Title
THE CONSTRUCTION AND IMPLEMENTATION OF A VISIBLE RANGE SPECTROPHOTOMETER FOR HIGH SCHOOL CHEMISTRY.
Creator
Helmick, Robert William, Florida Atlantic University
Abstract/Description
An inexpensive visible range spectrophotometer of good instructional value is prepared as a means of introducing instrumental analysis to the high school chemistry curriculum. Design and details of construction of the spectrophotometer are presented and five standard spectrophotometric experiments are adapted for high school chemistry. The five experiments are used to correlate results obtained with the inexpensive spectrophotometer to those obtained with a commercial spectrophotometer, the...

SELF-RELIANT APPROACH TO CHEMICAL INSTRUMENTATION
Title
A SELF-RELIANT APPROACH TO CHEMICAL INSTRUMENTATION.
Creator
N'GURUMO, N'DETENGA., Florida Atlantic University, Schultz, Franklin A., Charles E. Schmidt College of Science, Department of Chemistry and Biochemistry
Abstract/Description
This thesis was planned to aid teachers in introducing chemical instrumentation in upper secondary or undergraduate chemistry courses. The problems encountered and solved in the construction of a single beam visible range spectrophotometer, conductance bridge, and polarimeter are described. Experiments were carried out with each instrument to demonstrate their efficiency as compared to commercial models. Pertinent theory on the operation of the instruments is included that can be easily...
Show moreThis thesis was planned to aid teachers in introducing chemical instrumentation in upper secondary or undergraduate chemistry courses. The problems encountered and solved in the construction of a single beam visible range spectrophotometer, conductance bridge, and polarimeter are described. Experiments were carried out with each instrument to demonstrate their efficiency as compared to commercial models. Pertinent theory on the operation of the instruments is included that can be easily understood by students on this educational level. Construction of the instruments is simple and inexpensive, which allows schools with limited budgets to introduce topics on instrumentation into the chemistry curriculum.

ATOMIC MOLECULAR THEORY: A PROGRAMMED TEXT USED IN THE TEACHING OF BASIC ATOMIC AND MOLECULAR ORBITAL THEORY IN A HIGH SCHOOL PROGRAM OF CHEMISTRY
Title
ATOMIC MOLECULAR THEORY: A PROGRAMMED TEXT USED IN THE TEACHING OF BASIC ATOMIC AND MOLECULAR ORBITAL THEORY IN A HIGH SCHOOL PROGRAM OF CHEMISTRY.
Creator
SEVERANCE, H. WILSON, JR., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Chemistry and Biochemistry
Abstract/Description
This program was developed from necessity found in the teaching of molecular geometry to high school chemistry classes. Recent journals and textbooks were consulted in evaluation of the modern emphasis on instruction in molecular geometry at the high school level, and the topic was then developed fully for use in the chemistry course at the Ransom School, serving as a base for other instructional units. A self-teaching concept was employed in this manual in order that the student might...
Show moreThis program was developed from necessity found in the teaching of molecular geometry to high school chemistry classes. Recent journals and textbooks were consulted in evaluation of the modern emphasis on instruction in molecular geometry at the high school level, and the topic was then developed fully for use in the chemistry course at the Ransom School, serving as a base for other instructional units. A self-teaching concept was employed in this manual in order that the student might proceed at his own pace and according to his own needs. The principal intention was to familiarize the student with the shapes and configurations of various molecules and thereby to give him greater insight into the physical picture of molecular interaction in chemical reaction.

exploratory investigation of sources of individual differences in chemistry performance: The potential role of visual and verbal working memory and student affect in chemistry problem solving
Title
An exploratory investigation of sources of individual differences in chemistry performance: The potential role of visual and verbal working memory and student affect in chemistry problem solving.
Creator
Klein, Jason, Florida Atlantic University, Hecht, Steven A., Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description
This was an exploratory study of factors that predict individual differences in chemistry learning. Consistent with cognitive learning theory, working memory was assumed to be an important predictor of chemistry knowledge. Measures of chemistry affect, cognitive ability, demographics and mathematical ability were examined in relation to visual/schematic and algebra-like stoichiometry chemistry word problem solving ability and strategy use. 139 undergraduate students (91 females, 48 males) at...

Consistent with cognitive learning theory, working memory was assumed to be an important predictor of chemistry knowledge. Measures of chemistry affect, cognitive ability, demographics and mathematical ability were examined in relation to visual/schematic and algebra-like stoichiometry chemistry word problem solving ability and strategy use. 139 undergraduate students (91 females, 48 males) at a major Southeastern university participated in this study (Age ranged from 18 to 39 years (M = 20.70 years of age)). Perceived usefulness of the chemistry material, mathematical ability, GPA, and SGPA uniquely predicted conceptual stoichiometry problem solving ability.
