The aim of this study was to develop molecular genetics inquiry programs using the "eyes absent" gene of "Drosophila melanogaster." The program was composed of various molecular genetics experiments, including mutation observation, cross-breeding, searching for genetic information in web databases, gDNA extraction, and PCR.…

This article describes engaging students in two simple observations to address the concepts of changes of states, heat, temperature, and molecular potential and kinetic energy. It also discusses how these concepts can enable students to further explore and understand interesting and significant phenomena and research in multiple areas of science.…

The engagement of academics in organizational change in higher education institutions is generally understood as involving a wide range of behaviors, and previous studies have situated academics' actions at various points along a continuum between passivity and pro-activity. This article complements this approach by asking how--rather than in…

In order to address the challenges and restrictions given by a traditional classroom lecture environment, the top-down and bottom-up nanotechnology teaching modules were developed, implemented and evaluated. Then based on the hypothesis that instructors could further develop students' interest in this emerging area through the introduction of the…

A number of current reports are challenging educators of undergraduate biology students to increase the role, interactions and approaches of other disciplines. The goal stated in these reports is to produce a college graduate with the skills and competencies to solve pressing global problems such as producing ample food, fuels, and making health…

A study of chemistry students in an organic practical class, where they were required to work on their own, found considerable benefits in allowing them to work independently in a less organised environment. Although apprehensive at first, they soon gained a self-belief in their own abilities and were able to complete the course with minimal input…

The emerging field of nanotechnology has created a new frontier for the convergence of university and industrial research. In the United States, major federal investments provided a massive boom for this field over the decade. This paper reports on a case study of how the University at Albany came to establish the first college of nanotechnology…

Background: In this era of rapid technical advancement, there are growing debates around the idea of nanotechnology, which are both timely and controversial. Nanotechnology materials are being utilized in our daily lives in many ways, often without consumer knowledge. Due to the explosion of nanotechnology applications, there is a necessity to…

The large number of experimentally determined molecular structures has led to the development of a new semiotic system in the life sciences, with increasing use of accurate molecular representations. To determine how this change impacts students' learning, we incorporated image tests into our introductory cell biology course. Groups of students…

Size and scale cognition is a critical ability associated with reasoning with concepts in different disciplines of science, technology, engineering, and mathematics. As such, researchers and educators have identified the need for young learners and their educators to become scale-literate. Informed by developmental psychology literature and recent…

Education in nanotechnology presents major challenges in science literacy. One of these challenges relates to conveying size and scale-related concepts. Because of the potential difficulties in conveying concepts and ideas that are not visible to the naked eye, multimedia for learning could be an appropriate vehicle to deliver curricular materials…

There are significant contradictions in undergraduate organic chemistry textbooks as to the mechanism of nucleophilic substitution reactions at saturated secondary carbons. Some texts say that only the S[subscript N]2 mechanism operates, others say that solvolysis reactions go entirely by the S[subscript N]1 mechanism, while most texts say that…

Previous articles have dealt with the special problems arising when attempting to reduce reducible representations in continuous point groups. Current work, involving the programing of "projection operators" in connection with numerical computations, also shows the continuous groups to present special problems. These problems are…

Provides answers to these two questions: (1) What can be said about molecular structure? and (2) What are the foundations of theoretical chemistry? Indicates that students can be encouraged to think critically about primitive concepts of their subject (such as bonds and molecules) rather than passively accept them as truth. (JN)

Explores the extent to which, in polycyclic hydrocarbons, the total pi electron population tends to form small (4n plus 2) groups and avoid the formation of 4n groups. Also discusses the relation of this trend to resonance energy stabilizations. (JN)
