Science, technology, engineering, and mathematics (STEM) influence almost every aspect of our daily lives. However, despite the high demand for STEM occupational talent, the STEM pipeline continues leaking, with less than one-sixth of high school students pursuing STEM majors and only 50% of entering STEM majors matriculating into STEM fields.…

The Next Generation Science Standards propose a multidimensional model of science learning, comprised of Core Disciplinary Ideas, Science and Engineering Practices, and Crosscutting Concepts (NGSS Lead States, 2013). Accordingly, there is a need for student assessment aligned with the new standards. Creating assessments that validly and reliably…

Development of the Jordan Performance Appraisal System (JPAS) was completed in 1996. This study examined the factor structure of the classroom observation instrument used in the JPAS. Using observed classroom instructional quality ratings of 1220 elementary teachers of Grades 1-6 in the Jordan School District, this study estimated the factor…

Social emotional skills and competencies are integral to student success at home, school, and in the larger community. Extant research also consistently demonstrates that social emotional skill deficits are associated with various adverse outcomes.

The purpose of this study was to develop an instrument for higher education administrators to assess their social media practices during the admissions cycle. The instrument collects data from students on their perceptions about the quality of the institution's social media activities. A review of relevant literature was completed, and experts…

In this study, I investigated the effectiveness of a creativity-support system that I developed in the level editor of a learning game called "Physics Playground" on improving college students' creativity. Moreover, I investigated the validity and reliability of an in-game assessment of creativity to measure students' creativity.…

Student surveys have gained prominence in recent years as a way to give students a voice in their learning process, and teacher self-reports have always been an effective instrument for revealing the planning, intentions, and expectations behind a given lesson. Though student and teacher surveys are widely used, extant research in education has…

The present dissertation investigated the impact of scales/scoring methods and prompt linguistic features on the measurement quality of L2 English elicited imitation (EI). Scales/scoring methods are an important feature for the validity and reliability of L2 EI test, but less is known (Yan et al., 2016). Prompt linguistic features are also known…

Given recent calls for advancing valid instrumentation in the field of cyberaggression, the present study evaluated construct validity and measurement invariance for the Cyberbullying Experiences Survey (CES) in a high school and college student sample. A series of confirmatory factor analyses (CFA), reliability analyses, and a nomological net…

This dissertation includes two independent research projects, one in astronomy education research and the other in planetary science/astrophysics research. In the first research effort, we investigate college students' conceptual and reasoning difficulties on the topic of planet formation pre-instruction. Through an analysis of over 1,000…

The purpose of this study was to analyze the use of reading strategies being implemented in an urban school district in the Southeast. This study was framed on the SIOP (Sheltered Instruction Observation Protocol) Model (Echevarria et al., 2017). SIOP is an instructional framework that has been used in K-12 schools since the 1980s.
