Direct linkSong Wang – ProQuest LLC, 2023
The central focus of my dissertation concerns the issue of representation. The issue of representation is important for science education research for two reasons: (1) the use of external representation in science teaching and learning, particularly in chemistry education, is ubiquitous as microscopic entities are not directly visible, and (2) the…

Pagan-Munoz, Anyeliz – ProQuest LLC, 2022
This qualitative study examines the semiotic meanings communicated through multiple representations in the teaching of an advanced undergraduate course in biology. Scientific discourse is intrinsically multimodal in nature; in other words, science is discussed and researched using multiple modes that convey meaning (Lemke, 1998). Therefore, to…

Ostergren, Marilyn – ProQuest LLC, 2013
Visuals (maps, charts, diagrams and illustrations) are an important tool for communication in most scientific disciplines, which means that scientists benefit from having strong visual communication skills. This dissertation examines the nature of competence in visual communication and the means by which scientists acquire this competence. This…

Busch, Melanie M. D. – ProQuest LLC, 2011
An array of north-striking, left-stepping, active normal faults is situated along the southwestern margin of the Gulf of California. This normal fault system is the marginal fault system of the oblique-divergent plate boundary within the Gulf of California. To better understand the role of upper-crustal processes during development of an obliquely…

Harris, Daniel Wyatt – ProQuest LLC, 2012
Research examining animation use for student learning has been conducted in the last two decades across a multitude of instructional environments and content areas. The extensive construction and implementation of animations in learning resulted from the availability of powerful computing systems and the perceived advantages the novel medium…
