Within the scope of this investigation, educational instruments grounded on materialist ontology were employed to undertake a semantic analysis of the concepts of cell and the mechanisms of living organisms as they appear in biology and natural science textbooks. Drawing upon the ontological categories applied to distinct biological system levels,…

Mechanistic reasoning, or reasoning systematically through underlying factors and relationships that give rise to phenomena, is a powerful thinking strategy that allows one to explain and make predictions about phenomena. This article synthesizes and builds on existing frameworks to identify essential characteristics of students' mechanistic…

Audrey Sillick's article, first printed in 1988, provides a theory base for Maria Montessori's foundational emphasis on the biological sciences and the sustainability of a living, organic planet Earth as part of the educational process "of becoming more fully human." Ms. Sillick helps link primary-level biology with the special energy…

Educational strategies have evolved over the years due to research breakthroughs and the application of technology. By using the latest learning innovations, curriculum and instructional design can be enhanced and strengthened. Also, as learners move away from traditional scholarly media and toward technology-based education, students gain an…

Using the life sciences, this article first reviews essential features of the "NRC Framework for K-12 Science Education" that provided a foundation for the new standards. Second, the article describes the important features of life science standards for elementary, middle, and high school levels. Special attention is paid to the teaching…

With the world population recently surpassing seven billion people, it is critical for students to consider how such growth can lead to limited resources. Both the idea of diminishing resources and the magnitude of enormous numbers can be difficult for children (and many adults) to fully comprehend. For this particular lesson, the authors chose to…

This study aims to evaluate primary school Life Sciences (1st, 2nd, and 3rd grades) and Social Sciences (4th, 5th, and 6th grades) course books in terms of gender discrimination. This study is a descriptive study aiming to evaluate the primary school Life Sciences (1st, 2nd, 3rd grades) and Social Sciences (4th, 5th, and 6th grades) course books…

The purpose of this descriptive study was to investigate inservice elementary and middle school teachers' conceptions of photosynthesis and respiration, basic concepts they are expected to teach. A forced-choice instrument assessing selected standards-based life science concepts with non-scientific conceptions embedded in distracter options was…

"Community," "assemblage," "network," "complex," "interdependent," "web," and "synergism"--definitions of an ecosystem often include these words to highlight the dynamic interrelated workings of plants and animals with their physical environment. Young children don't understand the complexities of ecosystems, but they can begin to understand that…
