Özalemdar, Lütfiye – Journal of Turkish Science Education, 2019
The purpose of this study is to disclose the units and topics including the concept of water within 9th, 10th, 11th and 12th grades' biology textbooks that were chosen by the Ministry of National Education (MoNE) Head Council of Education and Morality (HCEM), and provide an overview of the whole content that mentions the concept of water. This…

Marvel, Stephen C.; Kepler, Megan V. – American Biology Teacher, 2009
It is important for students to be exposed to the concept of osmotic pressure. Understanding this concept lays the foundation for deeper discussions that lead to more theoretical aspects of water movement associated with the concepts of free energy, water potential, osmotic potential, pressure potential, and osmotic adjustment. The concept of…

Kowles, Richard V. – Bioscene: Journal of College Biology Teaching, 2010
Cell water relationships are important topics to be included in cell biology courses. Differences exist in the control of water relationships in plant cells relative to control in animal cells. One important reason for these differences is that turgor pressure is a consideration in plant cells. Diffusion and osmosis are the underlying factors…

Friedler, Y.; And Others – 1985
This study identified students' conceptual difficulties in understanding concepts and processes associated with cell water relationships (osmosis), determined possible reasons for these difficulties, and pilot-tested instruments and research strategies for a large scale comprehensive study. Research strategies used included content analysis of…
