This paper describes an introductory biology course for undergraduates that heavily incorporates quantitative problem solving in activities and homework assignments. The course is broken up into a series of units, each organized around a motivating biological question or theme. Homework assignments address the theme or question, and typically…

Educational Scaffolding was first mentioned in 1976 by Wood et al. Several examples for scaffolding in chemistry are also known from the literature. As written scaffolds, stepped supporting tools to support students while solving problems in organic chemistry were developed, applied, and evaluated. Although the students rated the tool as very…

With the rapidly growing field of nanotechnology, there has been a pressing need to teach non-science undergraduate majors how to critically interpret science in popular media and news sources. The present work introduces students to chemistry concepts through the lens of relatable nanotechnology applications, including electronics, medicine,…

The purpose of this study is to investigate teachers' understanding and knowledge of computational estimation, and teaching practice toward to computational estimation. There are six fifth-grade elementary teachers who participated in this study; three teachers with mathematics/ science major and three teachers with non-mathematics/science major.…

A novel course using green chemistry as the context to teach general chemistry fundamentals was designed, implemented and is described here. The course design included an active learning approach, with major course graded components including a weekly blog entry, exams, and a semester project that was disseminated by wiki and a public symposium.…

A central goal of nonmajors chemistry courses is to instill within students the sense that chemistry does not occur in a vacuum but rather permeates everyday life. To encourage students to consider chemistry within the broader context of society and public policy, a week-long module in a survey course for nonmajors was designed to connect…

This paper reports part of the results of research on chemical problem solving behavior of pre-service teachers in Plateau and Northeastern states of Nigeria. Specifically, it examines and describes the methods used by 204 pre-service teachers in solving quantitative problems from four topics in chemistry. Namely, gas laws; electrolysis;…

Adaptive tools and techniques for lecture instruction were developed for a blind student in a nonmajors college chemistry course. These adaptive instructional aids assisted the student in writing and balancing chemical reactions, calculating unit conversions and concentrations, drawing Lewis dot structures, understanding structural representations…

Provides a method to help students understand problem-solving techniques used in introductory physics courses. (MVL)

The purpose of this study was to analyze the errors made by students solving genetics problems. A sample of 10 non-science undergraduate students was obtained from a private college in Northern New Jersey. The results support prior research in the area of genetics education and show that a weak understanding of the relationship of meiosis to…

Describes a problem-based human biology course for undergraduate nonscience majors. Discusses the nature of problem-based learning, effectiveness of problem-based learning in a nonmajors' science course, course development, and implications. Contains 14 references. (JRH)

The purpose of this investigation was to identify and describe the differences in the methods used by experts (university chemistry professors) and nonscience major introductory chemistry students, enrolled in a course at the university level, to solve paired algorithmic and conceptual problems. Of the 180 students involved, the problem-solving…

Describes a non-laboratory science course for nonscience majors that actively engages students in a variety of learning activities. Highlights students' positive evaluations of the course. Also describes active learning experiences incorporated into the course. (JRH)

Discusses the lack of study skills found among non-science majors. Provides examples of how science courses differ from other courses. Gives some methods to help students study more effectively. (MVL)

In its use of complex, real-world problems to introduce concepts and motivate learning in an active and cooperative learning environment, problem-based learning is a powerful alternative to the passive lecture in introductory college science. Use of technology and multimedia instruction, focus on large classes, and use of interdisciplinary…
