Addresses some of the problems inherent both in traditional didactic science teaching and in approaches based on theories of conceptual change. Argues for helping students to acquire a better understanding of science (through an anthropological approach) and a better understanding of themselves as learners and science initiates. (Author/MM)

Participants in 2 experiments interacted with computer simulations designed to foster understanding of scientific principles governing complex adaptive systems. The quality of participants' transportable understanding was measured by the amount of transfer between 2 simulations governed by the same principle. The perceptual concreteness of the…

To appreciate the true impact of scientifically based research on education, it may be useful first to understand the meaning of the various terms that the law employs as part of its definition of SBR (Scientifcally Based Research). The This article presents an explication from a Software & Information Industry Association publication titled…

The concept of flight for human beings has always been closely tied to imagination. To fly like a bird requires a mind that also soars. Therefore, good teachers who want to teach the scientific principles of flight recognize that it is helpful to share stories of their search for the keys to flight. The authors share some of these with the reader,…

In this article, the authors describe an activity developed to assist students with constructing their own understanding of Earth's history and provide questions to help teach the geologic time scale. The lesson is aligned to the following National Science Education Standards: Science as Inquiry, Earth's History, and Nature of Science. While…

Educating the public about safety issues related to severe weather is part of the National Oceanic and Atmospheric Administration's (NOAA) mission. This article deals with a poster entitled, "Severe Weather," that has been created by NOAA to help educate the public about hazardous weather conditions. The four types of severe weather highlighted in…

Accurately conveying the nature of science (NOS)--what science is and how it works--is common to most science education standards documents, including the "National Science Education Standards" and "Science for All Americans". Understanding the NOS is crucial to scientific literacy since mistaken ideas of science will likely affect students'…

A study was done to help teachers assist students in understanding the nature of science and evolution better. The study revealed that teacher-student interaction helps the students to enhance their knowledge and ability to proceed and succeed.

The simultaneous determination of cadmium and lead by multi-element atomic absorption spectrometry with electrochemical atomization is proposed by employing a problem-based approach. The reports indicate that the students assimilated the principles of the simultaneous atomic absorption spectrometry (SIMAAS), the role of the chemical modifier, the…

Teaching about forces provides a good opportunity to encourage children to start thinking about energy transfer. Children come into the classroom with a number of ideas about the nature of energy. These often become apparent when eliciting their ideas about forces, particularly when discussing "push" and "pull". In this article, the author…

Enquiry based learning is an important tool in science teaching. Students of Class XI (16-17 years old) were asked to hypothesise on the role of different pigments found in plants with non-green leaves. The majority hypothesised that these plants were devoid of chlorophylls and some other pigments performed the function of photosynthesis. Their…

Teaching Newtonian physics involves the replacement of students' ideas about physical situations with precise concepts appropriate for mathematical applications. This paper focuses on the concepts of "matter" and "mass". We suggest that students, like some pre-Newtonian scientists we examine, use these terms in a way that conflicts with their…

The treatment of pendulum motion in early 18th century Newtonian textbooks is quite different to what we find in today's physics textbooks and is based on presuppositions and mathematical techniques which are not widely used today. In spite of a desire to present Newton's new philosophy of nature as found in his "Principia" 18th century textbook…

It is argued that Galileo made an important breakthrough in the methodology of science by considering idealized models of phenomena such as free fall, swinging pendula and the like, which can conflict with experience. The idealized models are constructs largely by our reasoning processes applied to the theoretical situation at hand. On this view,…

Piaget's investigations into children's understanding of the laws governing the movement of a simple pendulum were first reported in 1955 as part of a report into how children's knowledge of the physical world changes during development. Chapter 4 of Inhelder & Piaget (1955/1958) entitled "The Oscillation of a Pendulum and the Operations of…
