One econometric rule of thumb is that greater dispersion in observations of the independent variable improves estimates of regression coefficients and therefore produces better results, i.e., lower standard errors of the estimates. Nevertheless, students often seem to mistrust precisely the observations that contribute the most to this greater…

The phenomenon of precession is necessary to explain the motion of footballs, gyroscopes, tops, the Earth, and many other interesting physical systems, but it was very hard for me to understand as a student and is very difficult to teach to students now. Many explanations of precession in physics textbooks are highly mathematical and hard to…

This paper is centered on getting students to understand the nature of science (NOS) by considering historical material in relation to modern philosophers of science. This paper incorporates the methodology of contrasting cases in the calculus-based introductory physics course on optics and modern physics. Students study one philosopher all…

The Introduction to Sociology course is usually the first contact that students have with the discipline of sociology. This course can determine whether students take other sociology courses or learn to use sociology in their lives as adults and citizens. "First Contact" identifies important issues facing instructors in introducing students to the…

Acceleration is a fundamental concept in physics which is taught in mechanics at all levels. Here, we discuss some challenges in teaching this concept effectively when the path along which the object is moving has a curvature and centripetal acceleration is present. We discuss examples illustrating that both physics teachers and students have…

To teach students how to write for the workplace and other professional contexts, technical writing teachers often assign writing tasks that reflect real-life communication contexts, a teaching approach that is grounded in the field's contextualized understanding of genre. This article argues to fully embrace contextualized literacy and better…

Hegel's teaching is often omitted or considered summarily in political philosophy courses. In order to reduce these difficulties, an introductory discussion of Hegel's political thought in the context of a dialogue is presented. (RM)

This textbook is an introductory mathematics course. It is a treatise of arithmetic, containing all the practical parts thereof; both in whole numbers, vulgar fractions, and decimals; likewise the theory of numbers, and their principal properties, demonstrated in a plain and easy manner.

This two-part series describes the structure of the stoichiometry course at North Carolina State University. The course had a variety of learning objectives, and several nontraditional pedagogies were used in the course delivery. This first paper outlines the course structure and policies, the preparation given to the teaching assistants who…

This textbook aims to fill the need of an Introduction to Chemical Analysis, solely designed for use in the laboratory. This text presents simple rules for conducting chemical analyses to help students arrive at the most reliable results. This third edition has increased the examples for practice in quantitative and especially volumetric analysis.…

This textbook is an elementary English course based upon two fundamental facts in regard to language: (1) the purpose of language is communication of thought; and (2) the use of language is an art. The book also provides a complete and progressive course of instruction in the use of the dictionary as an aid to both oral and written language.…

This book is developed to enable students to think clearly and critically about the scientific process of research. The author emphasizes that the ability to think clearly about research methods, reason through complex problems, and evaluate published research are important in today's changing educational landscape. Students using this book will…

Model-eliciting activities (MEA), specially designed client-drive, open-ended problems, have been implemented in a first-year engineering course and in secondary schools. The educational goals and settings are different, but the design of an MEA enables it to be versatile. This paper will introduce the reader to the principles that guide MEA…
