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.

Show moreRaman spectroscopy based activities were developed and implemented into the first year chemistry undergraduate curriculum. The implementation of these experiences and experiments and the utility of Raman spectroscopy as a teaching tool to convey anchoring chemistry concepts using a hands-on Raman spectroscopy based approach are discussed. Fundamental principles of chemistry, such as the interaction of light with matter, molecular bonding, equilibrium, and acid base reactions are facilitated through use of these Raman spectroscopy based experiments and experiences. An assessment of student learning gains as a result of participation in a Raman spectroscopy experience was also conducted and is discussed.

COMPARISON OF TWO COMMUNITY COLLEGE GENERAL CHEMISTRY CURRICULA AND AN ANALYSIS OF SELECTED PREDICTORS OF STUDENT SUCCESS
Title
A COMPARISON OF TWO COMMUNITY COLLEGE GENERAL CHEMISTRY CURRICULA AND AN ANALYSIS OF SELECTED PREDICTORS OF STUDENT SUCCESS.
Creator
ROSEN, JOHN FREDERICK., Florida Atlantic University
Abstract/Description
This study compared two approaches to the instruction of general chemistry. One approach was a three semester sequence in which all students, regardless of previous chemistry background, began in the first course of the sequence. The other approach was only two semesters long but required students to either have completed a separate one semester chemistry preparatory course or demonstrated prior preparation in chemistry. The Toledo Chemistry Placement Exam was used to determine whether...
Show moreThis study compared two approaches to the instruction of general chemistry. One approach was a three semester sequence in which all students, regardless of previous chemistry background, began in the first course of the sequence. The other approach was only two semesters long but required students to either have completed a separate one semester chemistry preparatory course or demonstrated prior preparation in chemistry. The Toledo Chemistry Placement Exam was used to determine whether students had enough of a chemistry background to begin the two semester general chemistry sequence. As a result of the study, future chemistry students may be placed into either the preparatory chemistry course or the two semester sequence of general chemistry based upon a prediction resulting from a composite of the Toledo exam and the reading comprehension exam score. Students with low reading comprehension will be advised to take a developmental reading course as well as the preparatory chemistry course.

DESK-TOP KITS IN THE TEACHING OF INTRODUCTORY CHEMISTRY IN THE COMMUNITY COLLEGE: AN APPROACH BASED ON THE PIAGETIAN MODEL.
Creator
Baker, Marion Hale, Florida Atlantic University, Cook, Joseph B., Foley, Jack L.
Abstract/Description
Recent literature has suggested that many entering college students have not yet reached Piaget's formal operational level of intellectual development. The material in introductory chemistry, however, requires formal operational thought processes and chemistry instruction typically assumes that this level has been reached by students.

Show moreRecent literature has suggested that many entering college students have not yet reached Piaget's formal operational level of intellectual development. The material in introductory chemistry, however, requires formal operational thought processes and chemistry instruction typically assumes that this level has been reached by students. The premise of this study was that if many introductory chemistry students have not yet reached formal operational levels but work exclusively at the concrete operational stage, instruction should be directed toward concrete thought processes with the aim of helping the student advance from the concrete to the abstract. Desk-top kits containing chemicals, model-building materials and demonstration devices were distributed to each student during lecture. Each student handled the materials, contructed models and performed his own demonstrations as concepts were introduced. Relationships between the material or process itself (e.g., solutions or precipitation), seen firsthand, and the symbolic representation of that material or process were stressed. This study has demonstrated that, by taking into account the intellectual level of the learner, greater growth and higher achievement can result for introductory chemistry students. It has presented evidence that the Piagetian model of intellectual development is a useful approach for chemical educators to pursue. Presentation of new material in concrete terms with individual handling of materials and models and the individual performance of demonstrations can help introductory chemistry students grow and achieve. It is interesting that, while this approach may be necessary for the concrete operational members of a class, the formal operational members can also benefit from it.

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.

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.

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.

Show moreThis study was designed to collect data to develop a basic chemistry course specifically tailored to the needs of the associate degree programs in the allied health fields offered by Florida community colleges. The assumption was made that many of the students have little or no background in chemistry . The paucity of chemical background was identified as deterring the understanding of physiology and biochemistry encountered in courses such as anatomy and physiology, nutrition, microbiology and pharmacological studies. A questionnaire was developed to elicit faculty perception of the importance of specified topics in chemistry, specifically in preparation for physiology. Topics for the questionnaire were selected from chemistry texts currently in use for introductory chemistry, organic chemistry and physiology. The consensus questionnaire indicated a preference for minimal laboratory experience; however, comments by the respondents indicated the desire for laboratory demonstrations with hands-on experience in metric measurements. Comments also indicated a preference for providing appropriate laboratory experience during work in each of the fields, rather than during a basic chemistry course. Comments suggested that the course in basic chemistry be considered as general education credit, rather than in-house credit. Many of the respondents stated the used for updating their knowledge of topics included on the questionnaire. This study included a discussion of the expense and time required for direct solicitation. Further, it is suggested that the research be expanded to include educational institutions other than those of Florida. The suggestion of further research is made to broaden the study.
