The Utility Of Table-Top Exercises In Teaching Nuclear Security, Christopher Hobbs, Luca Lentini, Matthew Moran
The Utility Of Table-Top Exercises In Teaching Nuclear Security, Christopher Hobbs, Luca Lentini, Matthew Moran
International Journal of Nuclear Security
In the emerging field of nuclear security, those responsible for education and training are constantly seeking to identify and engage with tools and approaches that provide for a constructive learning environment. In this context, this paper explores the nature and value of Tabletop exercises (TTX) and how they can be applied in the nuclear security context. On the one hand, the paper dissects the key components of the TTX and considers the broader pedagogical benefits of this teaching method. On the other hand, the paper draws lessons from the authors’ experience of running TTXs as part of nuclear security professional …
Stop Ruining Math! Reasons And Remedies For The Maladies Of Mathematics Education, Rachel M. Steinig
Stop Ruining Math! Reasons And Remedies For The Maladies Of Mathematics Education, Rachel M. Steinig
Journal of Humanistic Mathematics
Did you love math as a kid? Or was it ruined for you? Sadly, many people have had math ruined for them for various reasons. Some might say that it was because of not understanding what was going on, being bored in class, parental or societal pressure to achieve in math, not seeing a point in learning math, wrong amount of homework, grades, curriculum, physical concerns, mean teachers, or any number of things. This article delves into the many common reasons why math is ruined for so many kids, and offers solutions so that math can be enjoyable for everyone. …
Innumeracy: The Product Of Misrepresentation, Elizabeth Cundiff
Innumeracy: The Product Of Misrepresentation, Elizabeth Cundiff
Missouri S&T’s Peer to Peer
Innumeracy refers to one’s inability to understand mathematics. Or, more simply, innumeracy is mathematical illiteracy. The main problem with innumeracy is the fact that most of society does not see it as a problem. In fact, many people boast about their innumeracy. Consider a table of five people at a restaurant: they split the check and attempt to calculate the tip. More often than not, at least one individual at the table will joke about the fact that they don’t know how to do make that simple calculation. This flippancy toward the prevalence of mathematics has become an accepted norm, …
Parts Of The Whole: Teaching Quantitative Reasoning In The Predator-Prey Model, Dorothy Wallace
Parts Of The Whole: Teaching Quantitative Reasoning In The Predator-Prey Model, Dorothy Wallace
Numeracy
The classical predator-prey equations are in nearly every differential equations text and mathematical biology text. Usually they are presented fait accompli, leaving the student to analyze them or play with a computer program. Here we show that the process of fully understanding where these equations come from and how they are derived provides numerous opportunities to teach or reinforce quantitative reasoning skills necessary to future scientists. This example is used to invoke logic, systems thinking, causal reasoning, understanding functions of one or more variables, quantities versus rates of change, proportional reasoning, unit analysis, and comparison to data.
A Guided Inquiry-Based Laboratory Experiment: Synthesis And Characterization Of Various Phthiocol Complexes, Turina Jangula
A Guided Inquiry-Based Laboratory Experiment: Synthesis And Characterization Of Various Phthiocol Complexes, Turina Jangula
The Journal of Undergraduate Research
Despite proven effectiveness of constructivist guided-inquiry based instruction for college chemistry courses, teaching in advanced chemistry courses such as inorganic chemistry remains very much traditional. This persistence of traditional instructional approaches could be attributed to the lack of inquiry-based curriculum materials for these courses. In this paper a guided-inquiry based inorganic laboratory experiment on the synthesis and characterization of phthiocol complexes with four different metals is presented along with suggestions for implementation as a laboratory activity. The experiment is unique in terms of its development based on a social constructivist framework and has student discussion and conceptual understanding of inorganic …
