I'M Going Cycle Every Day, Lauren Nguyen

LSU Master's Theses

Many designers and scientists have been able to integrate design and science in their respective fields to create works that effectively inform their audiences of complicated subjects. Each of these individuals can express their creativity and viewpoint of the subject matter in a way that is interesting, visually appealing, and informative. Using the medium of graphic design, I created printed posters that represent the way I view the processes of the human body that are technical, yet also visually appealing.

My thesis exhibition walks my audience through the biological cycles that maintain the human body on an everyday basis from …

The Characterization Of Alpha-Carbonic Anhydrases Through Mutagenesis And Subcellular Localization In Arabidopsis Thaliana, Lance E. Pounds

LSU Master's Theses

Carbonic anhydrases (CAs) are zinc metalloenzymes which catalyze the interconversion of carbon dioxide and bicarbonate. It is hypothesized that CA activity facilitates CO₂ flux in leaf mesophyll cells to maintain optimal rates of photosynthesis or to maintain a pool of inorganic carbon for other metabolic processes. There are three classes of CAs (α, β, and γ) in the model plant Arabidopsis thaliana. The βCAs and γCAs have been well studied, but the αCAs have received relatively little study. There are eight αCA genes in Arabidopsis. This study investigates which αCAs are expressed in shoots, their tissue-specific expression, their …

Effects Of Traditional Versus Electronic Note Taking In A High School Biology Classroom, Chelsea Ann Duhon

LSU Master's Theses

This study investigated the effect of traditional and electronic note taking on student achievement and engagement in a Louisiana high school biology classroom. Over a 20-week period, traditional students (n= 58) took notes using pencil and paper and electronic note takers (n=46) used their laptop computers. Each group of students was given identical pre and posttests covering three units and a practice End of Course exam. Normalized learning gains were compared for each unit and suggest there is no significant difference in academic achievement between the traditional note takers and the electronic note takers. An attitudinal survey was also administered …

The Effect Of Teaching Biology Concepts With Animations Compared To Static Cartoons On Content Retention, Rebecca Adams Polk

LSU Master's Theses

This study explores the effect of animations versus static cartoons on students’ content retention in a high school biology classroom. Students were pre-tested prior to the introduction of content in three units of study: cellular transport, protein synthesis, and mitosis. After instruction on the topic via PowerPoint presentations, students were randomly assigned to either the test group or experimental group for each unit. The control group was removed from the room and given a series of static cartoons with captions to view. The experimental group viewed an animation on the topic, accompanied by teacher narration, which consisted of the captions …

Technology In The Classroom: Effect Of Student Blogging On Learning Gains In A High School Classroom, Mandy Lynn Lebourgeois

LSU Master's Theses

This study explores the benefits of student use of web logs (blogs) in a high school Biology classroom. Students were assigned to blog by answering questions on topics from the Miller and Levine (2010) Biology textbook, which correlated to the Louisiana Grade-Level Expectations (GLEs), benchmarks that should be familiar to students at the end of a course. Raw gains (from pretest to posttest) were compared for the study group of 124 ninth and tenth grade students to determine if blogging increased student learning gains by increasing student accountability. The Louisiana Enhanced Assessment of Grade-Level Expectations (EAGLE) test bank was used …
