Evolving Scientific Vocabulary And Language In Middle School Classrooms: Babbling And Gargling On The Way To Scientific Understanding, Merryn Cole, Thomas Ryan, Jennifer Wilhelm

Taboo: The Journal of Culture and Education

While scientific vocabulary is important, it can often become problematic for students. Sometimes, those words can become a barrier to participation or act as a gatekeeper to success in the science classroom. Under the Next Generation Science Standards, middle school students are expected to model Earth-Moon-Sun motions to explain Moon phases, eclipses, and seasons (NGSS Lead States, 2013). Using a phenomenography lens, we investigated the ways in which students seeing the Moon in nature and related classroom experiences translate into a mental model of lunar phases and how vocabulary is used to communicate these models. Eighth-grade students from three urban …

A Combined Approach To Evaluating Student Engagement In A Virtual Laboratory Environment, Aster Sigel

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study measured student engagement with galvanic skin response (GSR) using a one group randomized pretest–posttest design in a science, technology, engineering, and mathematics (STEM) learning environment to develop effective intervention strategies for engaging students in STEM learning experiences. Student engagement is a multi-dimensional interrelated construct, consisting of emotional, behavioral, and cognitive components, and varies in different subjects and learning environments. Student engagement in higher education is associated with academic achievement, retention, and graduation. In this study, the emotional, behavioral, and cognitive engagement data of 30 college students were obtained using self-report surveys, observation and physiological data, which was recorded …

Research Mentoring And Scientist Identity: Insights From Undergraduates And Their Mentors, Rachael D. Robnett, Paul A. Nelson, Eileen L. Zurbriggen, Faye J. Crosby, Martin M. Chemers

Psychology Faculty Research

Background Mentored research apprenticeships are a common feature of academic outreach programs that aim to promote diversity in science fields. The current study tests for links between three forms of mentoring (instrumental, socioemotional, and negative) and the degree to which undergraduates psychologically identify with science. Participants were 66 undergraduate-mentor dyads who worked together in a research apprenticeship. The undergraduate sample was predominantly composed of women, first-generation college students, and members of ethnic groups that are historically underrepresented in science. Results Findings illustrated that undergraduates who reported receiving more instrumental and socioemotional mentoring were higher in scientist identity. Further, mentors who …

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 …

Preview-View-Review: Increasing Academic Access For Students With Intellectual Disabilities Who Are English Learners, Dolores Marie Williamson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Recent changes to federal education laws for students with and without disabilities have kindled an increased interest in implementing evidence-based practices for teaching academic skills to all students, including students with severe disabilities and students learning English. Teaching students with significant disabilities who are learning English poses a unique set of challenges. To date, no research has been conducted on teaching science to students with significant intellectual disabilities who are learning English.

This study was designed to measure the effect of an evidence-based science curriculum, delivered in both English and Spanish using the preview-view-review (PVR) strategy, on the science vocabulary …

The Hidden Stem Economy: The Surprising Diversity Of Jobs Requiring Science, Technology, Engineering, And Math Knowledge, Jonathan Rothwell

Brookings Scholar Lecture Series

Policy and businesses leaders have argued that there is a shortage of highly educated workers in professional occupations related to science, technology, engineering, and math (STEM). Critics have countered that Ph.D scientists often face a difficult academic labor market and do not necessarily earn higher wages than other professionals. Yet, both sides of the STEM debate have been relying on an ill-defined definition of STEM work. Using a detailed survey of worker knowledge requirements, this research project redefines STEM jobs based on the level of knowledge required in STEM fields to perform occupations. The results uncover two facts previously unrecognized …
