A number of scholars have shown the prevalence of multiple metaphors in biological conceptions of the living cell. However, there is little research into unpacking these metaphors to understand their ideological implications for scientific knowledge and science education. In this paper, I perform a critical discourse analysis of the representation…

Many physics textbooks describe the way in which a capacitor in an RC circuit charges and discharges over time. A circuit that consists of a capacitor that is connected to a voltage divider as shown in Fig. 1 is commonly addressed, but the textbooks limit the discussion to the time immediately after the switch is closed and a long time after the…

For physical measurements, the compositions of solutions, especially electrolyte solutions, are expressed in terms of molality rather than mole fractions. The development of the necessary thermodynamic equations directly in terms of molality is not common in textbooks, and the treatment in the literature is not very systematic. We develop a…

In this study, we examined opportunities for reasoning and meaning making that read-alouds of children's literature science information books and related hands-on explorations offered to young Latina/o students in an urban public school. Using a qualitative, interpretative framework, we analyzed classroom discourse and children's writing…

For students to develop an understanding of science content and processes, teachers must create classroom environments in which students use inquiry to understand the natural world. However, teachers frequently find it difficult, if not impossible, to demonstrate complex scientific concepts, which textbooks often fail to properly explain. During…

Between 1880 and 1920 the way science was taught in American High Schools changed dramatically. The old "lecture/demonstration" method, where information was presented to essentially passive students, was replaced by the "laboratory" method, where students performed their own experiments in specially constructed student laboratories. National…

This textbook integrates chemistry and art with hands-on activities and fascinating demonstrations that enable students to see and understand how the science of chemistry is involved in the creation of art. It investigates such topics as color integrated with electromagnetic radiation, atoms, and ions; paints integrated with classes of matter,…

Explains the "Overview-Case Study Method" for teaching high school physics which has evolved from the author's experience/success with a program in which 90 percent of the high school's students take physics as an elective. Areas considered include methods, case studies, textbooks, multilevel physics, qualitative physics, and real-life…

A single heartbeat is a complicated process. In Dutch upper secondary biology textbooks this process is illustrated by the classical Wiggers diagram, which usually shows different heart-related quantities, like voltage (ECG), blood pressure, and the heart sounds. It may help students to understand the nature of the Wiggers diagram if they perform…

This book is the teacher's edition to the 1987 edition of the Biological Sciences Curriculum Study Green Version textbook. It contains directions for teaching with this version, a description of the accompanying materials, teaching strategies by chapters, lists of useful software, safety guidelines, a materials list, chemical safety information,…

As a part of a doctoral thesis considering the history of teaching physical and chemical change, 641 chemistry/science textbooks have currently been examined. These books are from many different countries and date from the eighteenth century to the present time. The books have described a wide variety of experiments to illustrate the difference…
