We recently shared our design of a two-semester flipped organic chemistry course, in which we gave students in-class quizzes to incentivize attendance and watching the lecture videos in advance. With a second iteration, we planned to make the video-watching experience more engaging. We accordingly hypothesized that if students completed short at-home quizzes while watching the videos, then attentiveness, engagement, and learning would increase. We tested this with a later section of the course, dividing the material into 13 units. For units 1-6, we gave in-class quizzes; for 7-13, quizzes were at home. Although units 1-6 and 7-13 covered different material, …

When asked what plants need for photosynthesis, many students can correctly recall the reaction equation and state that plants require CO2, H2O, and light. Many students, however, do not understand that these reactants are the raw materials plants use to make sugars and instead believe that they are food for plants. Moreover, when questioned further, students often voice the idea that plants get their food from the soil (Kestler 2014). This is consistent with findings that fewer than half of current middle and high school students have a correct understanding of the process of photosynthesis (AAAS 2015). We developed this …


Nickel Phosphide On Boron-Doped Alumina: New Catalysts For Heteroatom Removal Reactions, Catherine E. Miles Apr 2016

Nickel Phosphide On Boron-Doped Alumina: New Catalysts For Heteroatom Removal Reactions, Catherine E. Miles

WWU Honors College Senior Projects

The effects of boron addition to an alumina (Al2O3) support on the hydrodesulfurization (HDS) properties of nickel phosphide (Ni2P) catalysts have been investigated. The B-Al2O3 supports were prepared by a wetness impregnation method using boric acid (H3BO3) to dope the alumina support with 0-7.2 wt% B, yielding a boron oxide (B2O3) layer of monolayer thickness on the surface of the Al2O3 support. Ni2P precursors were prepared on the B-Al2O3 supports in two ways: 1) impregnation …


Carbon Nanotubes And Graphene As Additives In 3d Printing, Lara A. Al-Hariri, Branden Leonhardt, Mesopotamia Nowotarski, James Magi, Kaelynn Chambliss, Thaís Venzel, Sagar Delekar, Steve Acquah Jan 2016

3D printing is a revolutionary technology for the consumer and industrial markets. As the technology for 3D printing has expanded, the need for multi-materials that support fused deposition modeling and other forms of additive manufacturing is increasing. 3D printing filaments infused with carbon nanotubes and graphene are now commercially available, with the promise of producing conductive composites. This chapter explores some of the research, products, and challenges involved in bringing the next generation of functional printing materials to the consumer market.


I Want To Be The Inquiry Guy! How Research Experiences For Teachers Change Beliefs, Attitudes, And Values About Teaching Science As Inquiry, Deborah Herrington, Senetta F. Bancroft, Molly M. Edwards, Caroline J. Schairer Jan 2016

I Want To Be The Inquiry Guy! How Research Experiences For Teachers Change Beliefs, Attitudes, And Values About Teaching Science As Inquiry, Deborah Herrington, Senetta F. Bancroft, Molly M. Edwards, Caroline J. Schairer

Peer Reviewed Articles

This qualitative study examined how and why a research experiences for teachers (RET) influenced middle and high school science teachers’ beliefs, attitudes, and values about teaching science as inquiry. Changes teachers reported after participating in the RET ranged from modifying a few lessons (belief change) to a comprehensive revision of what and how they taught to better reflect inquiry (attitude change). Some teachers who described comprehensively changing their instruction also described implementing actions meant to change science education within their respective schools, not just their own classrooms (value change). We present how and why teachers went about changes in their …


Building Data And Information Literacy In The Undergraduate Chemistry Curriculum, Yasmeen Shorish, Barbara A. Reisner Jan 2016

Building Data And Information Literacy In The Undergraduate Chemistry Curriculum, Yasmeen Shorish, Barbara A. Reisner

Department of Chemistry and Biochemistry - Faculty Scholarship

The Literature and Seminar sequence at James Madison University has been used to develop the chemistry information literacy skills of chemistry majors for over four decades. These courses have been continually updated to emphasize information literacy skills for the twenty-first century. This chapter describes the methods that have been developed to improve chemical, data and general information literacy at a large, public, primarily undergraduate institution. The focus of the first semester course, described in this chapter, is on skill building rather than teaching specific resources. It is a model of integration and collaboration between chemistry faculty and chemistry librarians. Changes …

SIUE Faculty Research, Scholarship, and Creative Activity

Increasingly, studies are investigating the factors that influence student discourse in science courses, and specifically the mechanisms and discourse processes within small groups, to better understand the learning that takes place as students work together. This paper contributes to a growing body of research by analyzing how students engage in conversation and work together to solve problems in a peer-led small-group setting. This qualitative study evaluates video of Peer-Led Team Learning (PLTL) sessions in general chemistry, with attention to both the activity structures and the function of discourse as students undertook different types of problems across one semester. Our findings …
