Confidence Intervals In A High School Statistics Class, Alexander Chopyak

#### Confidence Intervals In A High School Statistics Class, Alexander Chopyak

*Mathematics, Engineering and Computer Science Undergraduate Theses*

In order to be a functioning member of society, it is important that a citizen understands basic statistics. One key topic in particular is confidence intervals. There are confidence intervals in everyday life, no matter if you are a person in college or just a person in society. Many claims about population rely on a sample and the statistics of confidence intervals. For example: We believe, with 95% confidence, that 40% ± 3% of Americans will approve a new law by Congress, meaning that we are 95% confident that any sample formed in this way will have a proportion or mean ...

Suggested Types Of Manipulatives To Aid In Teaching Geometry To Various Age Groups Of Students, Tessa Berg

#### Suggested Types Of Manipulatives To Aid In Teaching Geometry To Various Age Groups Of Students, Tessa Berg

*Mathematics, Engineering and Computer Science Undergraduate Theses*

Geometry is a complex and visual discipline. Because geometry includes abstract concepts, geometry teachers often use manipulatives to make concepts visible and tangible. In this thesis, the question is proposed: which types of manipulatives are most beneficial to which age groups based on student achievement, student engagement and the Common Core State Standards. This thesis analyzes the existing research about the use of different types of manipulatives with different age groups. The research was separated into age group brackets, kindergarten through second grade, third grade through fifth grade, sixth grade through eighth grade, and ninth grade through twelfth grade. The ...

The Role Of Math Modeling In The Common Core, Ashley Perez

#### The Role Of Math Modeling In The Common Core, Ashley Perez

*Mathematics, Engineering and Computer Science Undergraduate Theses*

Mathematics education in the United States has been through many reforms, the latest of which is the Common Core State Standards Initiative. While many of the old standards are modifications of the existing standards, the process of mathematical modeling introduced by the Common Core State Standards for Mathematics is one of the major changes. Modeling is a way to link the classroom to real world problems and enables students to problem solve, think critically, collaborate with other students, and use a variety of mathematical tools to answer problems. We first explore modeling within the Common Core State Standards Initiative for ...

A Cooperative Approach To The N-Solution Problem, Sean Murray

#### A Cooperative Approach To The N-Solution Problem, Sean Murray

*Chemistry and Physics Undergraduate Theses*

Collaboration is an ever-present element in scientific research today. Even within laboratories and research teams, colleagues need to analyze, interpret, and disseminate research outcomes individually. Despite this need, the interdependence of scientists is seldom emphasized. We have added collaborative skill to the learning outcomes of a qualitative analysis laboratory exercise. Student collaboration, interdependence and enjoyment were measured using an anonymous survey and showed a marked increase over the control group in all areas. Presented here is the design with results from the lab protocol testing phase.

A general chemistry laboratory that illustrates the effectiveness and benign nature of unconventional reaction media is outlined in a three step procedure: 1) a solventless condensation reaction between two solids, 2) an oxidative coupling reaction in the presence of a liquid carbon dioxide solvent, and 3) the synthesis of an organic-transition metal complex in aqueous solvent. This laboratory exercise is designed illustrate the advantages and utility of alternative solvents through a straightforward procedure with visually qualitative results while further exploring the function of solvents in the synthetic process. The laboratory experiments address waste prevention and the use of innocuous solvents ...

Rural Water Disinfection In The Developing World: Designing A General Chemistry Lab Experience, Mickey Doherty

#### Rural Water Disinfection In The Developing World: Designing A General Chemistry Lab Experience, Mickey Doherty

*Chemistry and Physics Undergraduate Theses*

A simple electrolysis apparatus was set up with a 10 wt% NaCl solution using a stainless steel cathode and a graphite anode to produce a hypochlorite ion solution. The hypochlorite ion solution was quantified to around 600 ppm by spectrophotometry analysis at 515 nm using N,N-diethyl-p-phenylenediamine (DPD). The efficacy of the hypochlorite solution was determined by contaminating a 1 ppm solution of the hypochlorite solution with the sulfide-producing bacterium, Salmonella typhimurium. At this level, the bacteria were not viable. The procedure used to generate the hypochlorite solution and determine its disinfection effectiveness was adapted to a lab experience for ...
