Early child development sequences were studied in the beginning of the 20th century and in the process uncovered some relevant conclusions about early post-natal life. This might have been the very beginning of some principles of what has become known as Developmental Psychology or how humans grow. The writer has tried to codify the essentials of…

A set of highly atom-economic experiments was developed to highlight the differences between acid- and base-catalyzed ester syntheses and to introduce the principles of atom economy. The hydrochloric acid-catalyzed formation of an ester was compared with the 4-dimethylaminopyradine-catalyzed ester synthesis.

Background: Previous models of the effects of feedback account for lower-order learning outcomes but do not adequately describe experimental findings for higher-order learning. Aims: Based on a connectionist model of feedback effects, this investigation aims to show that feedback that allows only one learner response facilitates…

Bernoulli's principle is being misunderstood and consequently misused. This paper clarifies the issues involved, hypothesises as to how this unfortunate situation has arisen, provides sound explanations for many everyday phenomena involving moving air, and makes associated recommendations for teaching the effects of moving fluids.

The evangelical tone and history of American culture has long been identified as a force for anti-intellectualism. The metaphors of educational reform are a demonstration of how this plays out. The very nature of the positivist social science research used to support proposed reform is anti-intellectual and feeds a debate that favors extremes over…

Historical stories of scientists provide an excellent opportunity to help students see that science is indeed a human endeavor and demonstrate the interrelationships among science, technology, and society. A number of engaging historical accounts illustrate characteristics of the nature of science. The story of Lise Meitner leads students through…

Conversations on the connection of art, beauty, and the aesthetic experience in science are gaining a voice in the science education community. This article provides a conceptual overview of the role of beauty and aesthetics in science and science education. It focuses on a discussion of four themes exploring beauty in scientific ideas and…

Today, geodesic domes are found on playgrounds, homes, over radar installations, storage facilities, at Disney's Epcot Center, and at World's Fairs. The inventor of the design, Buckminster Fuller, thought that geodesic domes could be used to cover large areas and even designed one to cover all of New York's Manhattan Island. This article details…

Over the last three decades many universities have offered various programmes related to Information Systems. However, the rapid changes in recent years demand constant evaluation and modification of education programmes. Recent challenges include, for instance, the move towards programmes that are more applied and professionally-orientated. The…

This study tracked the influence of explicit reflective instructional methods on cultural values, ethical and intellectual development, and the relationship of these with preservice teachers' views of nature of science (NOS). The researchers used the Views of Nature of Science Form B (VNOS B) to describe NOS views, the Learning Context…

This paper presents part of the findings from a comparative study on existing and proposed science curricula of grades IX-X in Bangladesh. It aims to explore relevant research to find out what ideas about science are recommended to include in school science curriculum, and then to compare the existing and proposed curricula in terms of ideas about…

Adapted primary literature (APL) refers to an educational genre specifically designed to enable the use of research articles for learning biology in high school. The present investigation focuses on the pedagogical content knowledge (PCK) of four high-school biology teachers who enacted an APL-based curriculum in biotechnology. Using a…

In this paper I respond to Ajay Sharma's "Portrait of a Science Teacher as a Bricoleur: A case study from India," by speaking to two aspects of the bricoleur: the subject and the discursive in relation to pedagogic perspective. I highlight that our subjectivities are negotiated based on the desires of the similar and competing discourses…

Discusses reasons for questioning the underlying assumptions of instruments designed to measure knowledge of the nature of science. Recommends that researchers recognize that conflicting models of science exist, and that each instrument related to these models must specify all philosophic assumptions. (MLH)

Discusses the problem of whether an explanation of the phenomena of life can be deduced from an exclusive reliance on causal relationship. Indicates that this exclusive reliance is not valid and adds the concept of anticipation. (GS)
