Examining The Training Transfer Practice Of A Financial Institution: An Action Research Study, Maria Lourdes Lourdes Gutierrez Dec 2018

Examining The Training Transfer Practice Of A Financial Institution: An Action Research Study, Maria Lourdes Lourdes Gutierrez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Many organizations rely on training to improve the skills and knowledge of its human resources. The underlying assumption is that employees will use what they learned when they return to the workplace. Although there is evidence that learning occurred it does not always result in transfer (Mosel, 1957). Transfer is an issue of concern for training practitioners. If despite the significant investment no return is realized, then the training is not effective and the investment is wasted. This action research study was conducted in a financial institution in the Southwestern United States. The purpose of this study was to (1) …

How Middle Level Science Teachers Visualize And Translate Motion, Scale, And Geometric Space Of The Earth-Moon-Sun System With Their Students, Jennifer Wilhelm, Merryn Cole, Cheryl Cohen, Rebecca Lindell

Teaching and Learning Faculty Research

We examined teachers’ spatial-scientific reasoning and the alternative conceptions they held regarding Earth-space content. While participating in a professional development (PD) workshop, teachers engaged in an integrated mathematics and science project-based unit designed to foster spatial reasoning and improve lunar-related conceptual understanding. The Purdue Spatial Visualization Test-Rotation (PSVT-Rot) and the Lunar Phases Concept Inventory (LPCI) were used to assess understanding. We found the teachers held similar alternative conceptions as their students. Moreover, we discovered that teachers had limited understanding of the Earth-Moon-Sun scale, motions, and geometric configurations. To determine how teachers’ spatial-scientific confidence and ability translated to their classroom practice, …

Exploring The Effectiveness Of Model-Based Instruction To Improve Sixth-Grade Students’ Science Content Knowledge, Scot D. Ewen May 2018

Exploring The Effectiveness Of Model-Based Instruction To Improve Sixth-Grade Students’ Science Content Knowledge, Scot D. Ewen

UNLV Theses, Dissertations, Professional Papers, and Capstones

The economy of tomorrow is uncertain, so students today need to be prepared for the known and unknown careers that lie ahead. Currently, not all students are expected to have equal career opportunities based on evidence from dropout and testing data (Brown & Brown, 2007; Kirsch, Braun, Yamamoto, & Sum, 2007), so educators should consider different methods of helping all students reach their potential. Modeling instruction is one method that might help diverse learners improve their scientific understandings and allow them to pursue careers in technology-oriented fields. A quasi-experimental study was conducted with 128 sixth grade students as participants. A …
