Cognitive load is the effort needed to process and store information in memory and can be measured via subjective, physiological, and performance methods. Virtual reality learning environments (VRLEs) enhance science aptitude and motivate students to pursue science careers. Cognitive load is divided into three types: intrinsic, extraneous, and…

This is potentially the first study that addressed the Puerto Rican high school students' chemistry knowledge acquisition using traditional teaching and Physics Education Technology. The problem addressed by this quantitative comparative quasi-experimental study was that students' showed a disadvantage on chemistry knowledge acquisition over other…

Statement of Purpose and Method of Study: Oculus Rift immersive virtual reality includes a headset and a computer and immerses the user into a three-dimensional experience. Immersive virtual reality learning experiences with classroom discussions are emergent, novel instructional methods. This standard exploratory study investigated an…

Achievement emotions are critical for students' academic performance and career choices. The previous literature has focused on one specific type of achievement emotions--test anxiety--in Western contexts and neglected other various emotions experienced in different occasions such as attending classes. The present study aims to address the…

Physical science instruction often involves modeling natural systems, such as electricity that possess particles which are invisible to the unaided eye. The effect of these particles' motion is observable, but the particles are not directly observable to humans. Simulations have been developed in physics, chemistry and biology that, under certain…

Augmented reality (AR) is an interactive system that allows users to interact with virtual objects and the real world at the same time. The purpose of this dissertation was to explore how AR, as a new visualization tool, that can demonstrate spatial relationships by representing three dimensional objects and animations, facilitates students to…

Online learning has seen an explosive growth at the K-12 level, however little research has used an experimental design approach to specifically examine the outcomes of delivery methods. This study examines what effect learning in an immersive learning environment (virtual world) has on student achievement and satisfaction with the lesson. To…

Any student seeking a high school diploma from the public school system in one U.S. state must pass the state's high school graduation test. In 2009, only 88% of students at one high school in the state met the basic proficiency requirements on the science portion of the test. Because improved science education has been identified as an explicit…

Background: The current mode of stoichiometry instruction employs a passive pedagogy that consists of students reading, listening, watching, and memorizing disembodied facts, procedures, and principles in preparation for future application. But chemistry students are often subsequently unable to apply this stoichiometry knowledge in equilibrium…

The significant increase of English Language Learners (ELLs) in the United States raises complex questions about how to provide these students with access to high quality education that can improve both their content knowledge of school subjects and their English proficiency, particularly their academic English proficiency. The development of…
