Can Less Be More? Study Load And Its Effect On Science Achievement Among Chinese Eighth-Grade Students, Xian Wu

Theses and Dissertations--Education Sciences

The present study addressed a core research question of “Can less be more?” concerning study load, which has become increasingly worrisome and controversial around the world. This idea reflects the philosophy of pursuing efficiency and effectiveness on learning, namely that a lighter study load may result in more successful academic achievement. The study adopted the IPO (input-process-output) model to address five interrelated research questions: 1) What are the structural characteristics of study load? 2) Is there any individual difference in study load? 3) What are the characteristics of teachers and schools under which students tend to have a heavier study …

A Tale Of Two Contexts: Mathematics Self-Efficacy Development Among Rural And Urban Students, Brianna L. Weidner

Theses and Dissertations--Educational, School, and Counseling Psychology

Self-efficacy, or a belief in one’s ability to complete a task, has been shown to predict student success and persistence. Rural students have a history of lower college enrollment and degree attainment than urban students. However, no studies have compared self-efficacy or its sources across rural and urban groups. The purpose of this study is to examine differences in how rural and urban middle school students develop self-efficacy and self-efficacy for self-regulated learning in the domain of math. Data were collected from 174 rural students and 1743 urban students in grades 6-8 in the southeastern United States. Measurement invariance analyses …

Assessing Stem Literacy In An Informal Learning Environment, Maureen Ann Lafemina Cavalcanti

Theses and Dissertations--Education Sciences

This mixed methods study investigated methods for assessing STEM literacy amongst middle grades students participating in an informal learning environment, specifically, a summer STEM camp. Adopting a situated perspective on STEM literacy, this dissertation employed psychometric techniques and discourse analysis to answer the overarching research question: How can STEM literacy amongst middle school students be assessed in the context of a summer STEM camp? An integrated review of literacy within and across STEM disciplines first offered a new direction for conceptualizing STEM literacy. With this understanding, subsequent research methods applied novel approaches for investigating STEM literacy in the context of …

Aspects Of Science Engagement, Student Background, And School Characteristics: Impact On Science Achievement Of U.S. Students, Larry J. Grabau

Theses and Dissertations--Educational, School, and Counseling Psychology

Science achievement of U.S. students has lagged significantly behind other nations; educational reformers have suggested science engagement may enhance this critical measure. The 2006 Program for International Student Assessment (PISA) was science-focused and measured science achievement along with nine aspects of science engagement: science self-efficacy, science self-concept, enjoyment of science, general interest in learning science, instrumental motivation for science, future-oriented science motivation, general value of science, personal value of science, and science-related activities.

I used multilevel modeling techniques to address both aspects of science engagement and science achievement as outcome variables in the context of student background and school characteristics. …

The Short Grit Scale: A Dimensionality Analysis, Caihong Li

Theses and Dissertations--Educational, School, and Counseling Psychology

This study aimed to examine the internal structure, score reliability, scoring, and interpretation of the Short Grit Scale (Grit-S; Duckworth & Quinn, 2009) using a sample of engineering students (N = 610) from one large southeastern university located in the United States. Confirmatory factor analysis was used to compare four competing theoretical models: (a) a unidimensional model, (b) a two-factor model, (c) a second-order model, and (d) a bi-factor model. Given that researchers have used Grit-S as a single factor, a unidimensional model was examined. Two-factor and second-order models were considered based upon the work done by Duckworth, Peterson, …
