Physical Variables in Freshwater Ecosystems
2018We consider three categories of physical variables that can be measured for different freshwater ecosystems: (1) variables measured or described at the catchment or sub-catchment scale (e.g., bathymetry, depth, topography, geology); (2) those in or near to the water (e.g., temperature, turbidity, solar radiation); and (3) variables used to describe the

Variables affecting physics achievement
Journal of Research in Science Teaching, 2009AbstractMuch research has focused on student views about physics concepts, with an emphasis on the identification of alternative conceptions, and how curricula and professional development may ameliorate the situation. However, there has been little work on determining the extent of, and in separating, the student and teacher/classroom level variables ...

Physical Variability of Sandy Beaches
1983This paper examines sandy beach types that exist in wave environments ranging from low ( 2.5m). Three basic beach types — reflective, intermediate and dissipative, composed of six beach states have been identified. Each beach state can be classified by its wave-sediment characteristics.
