Does Attainment Of Piaget's Formal Operational Level Of Cognitive Development Predict Student Understanding Of Scientific Models?, Richard Dennis Lahti
Does Attainment Of Piaget's Formal Operational Level Of Cognitive Development Predict Student Understanding Of Scientific Models?, Richard Dennis Lahti
Graduate Student Theses, Dissertations, & Professional Papers
Knowledge of scientific models and their uses is a concept that has become a key benchmark in many of the science standards of the past 30 years, including the proposed Next Generation Science Standards. Knowledge of models is linked to other important nature of science concepts such as theory change which are also rising in prominence in newer standards. Effective methods of instruction will need to be developed to enable students to achieve these standards. The literature reveals an inconsistent history of success with modeling education. These same studies point to a possible cognitive development component which might explain why …
Forecasting Groundwater Responses To Dam Removal, Antony Ray Berthelote
Forecasting Groundwater Responses To Dam Removal, Antony Ray Berthelote
Graduate Student Theses, Dissertations, & Professional Papers
This dissertation contains three papers describing groundwater system responses to dam removals and presents current and new methodologies that managers can use to proactively forecast and mitigate those impacts. The three papers bring together literature, data gathering, data analysis, testing, and modeling techniques that apply groundwater science to forecasting the response of groundwater systems to dam removal actions. Conceptual and numerical models developed as part of this work provide scientists, environmental consultants, regulators and managers with tools to assess the consequences of the removal of stream reservoirs on the adjacent and underlying groundwater system The first chapter/paper, Responses of Groundwater …
