We describe the implementation and effects of group problem solving in recitation sections associated with the general chemistry course at a small private science university. Recitation sections of approximately 45 students are used to supplement large (approximately 180 students) lecture sections. The primary goal of recitation is working in…

The authors engaged in an education experiment to determine if the integration of lab and lecture activities in zoology and botany proved beneficial to student learning and motivation toward biology. Their results revealed that this strategy positively influenced students' academic achievement, conceptual understanding, and ability to apply…

We have undertaken an integrated and collaborative approach to developing foundational skills of students in a first year, Introductory Biology course. The course is a large lecture and laboratory course with enrollments ranging from 800-1000 per year. Teaching and Learning experts were brought into the course as weekly "Foundation Skills for…

Understanding the scientific method fosters the development of critical thinking and logical analysis of information. Additionally, proposing and testing a hypothesis is applicable not only to science, but also to ordinary facts of daily life. Knowing the way science is done and how its results are published is useful for all citizens and…

Describes the construction of a projector assembly which can be used for both stereo- and time-lapse projection. (Author/GS)

This experiment uses a radioactive technique to determine the relative leaving abilities of chloride and iodide in nucleophilic substitution reactions. (DT)

Two experiments are described which illustrate preparative as well as mechanistic features of the reactions of halogens with alkanes and alkenes. (DT)

Laser physics can be addressed and presented at three different levels of conceptual and mathematical sophistication. In this paper, the three levels are defined and characterized. Advantages and disadvantages of each approach are discussed, and recommendations for choosing a particular approach to match student level and interest are offered.…

This textbook provides a partial course of reading in chemistry for college men and general readers, and indicates further matter of an interesting and instructive nature. It is the first volume of a series of readers which will contain reprints of modern papers and addresses, gathered from many sources and edited to suit the purposes herein…

Unlike many elementary presentations on heat, this monograph is not restricted to explaining thermal behavior in only macroscopic terms, but also developes the relationships between thermal properties and atomic behavior. "It relies at the start on intuition about heat at the macroscopic level. Familiarity with the particle model of mechanics,…

To help those concerned with the present shortage of funds, the Council on Education for the Geological Sciences (CEGS) has compiled this list of possible sources of support for undergraduate geology programs. The $1,200 fund sources included have been subdivided into five ranges, according to last known annual amounts given for all purposes.…

The purpose of this investigation was to determine if the level of aspiration procedure consisting of knowledge of results plus goal-setting possesses a motivational property as reflected in performance on subject matter criterion instruments above that of knowledge of results alone. The sample consisted of 255 students enrolled in a three-term…

This is Part II in a series on Fourier transforms. Described are Fourier transform techniques using spectrometers in chemistry. Advantages of the technique are discussed. (RH)

This is Part II in a series on Fourier transform infrared spectroscopy (FT-IR). Described are various advantages of FT-IR spectroscopy including energy advantages, wavenumber accuracy, constant resolution, polarization effects, and stepping at grating changes. (RH)
