Students' Mental Models Of Electricity In Simple Dc Circuits, Andrew C. Isola Iii

Dissertations

This study presents the results of research into middle school students' knowledge about the nature and mechanisms of action of electricity in simple DC circuits. Sixth, seventh, and eighth graders (n=99) were asked a series of questions about the roles of bulbs, batteries, wires, and electricity in circuits. Almost half the number of students (n=42) were found to have used detailed, well-defined, and logically consistent mental models based on their responses. A total of 15 different detailed mental models were documented in these students that belonged to one of four different general model types: (1) round trip flow using both …

The Use Of Curriculum-Based Measurement To Evaluate The Effects Of A Remedial Education Program, Michael D. Hixson

Dissertations

This study examined the effectiveness of two Direct Instruction programs: Corrective Reading: Decoding and Connecting Math Concepts. The effectiveness of the interventions was evaluated using a single-subject experimental design with curriculumbased measurement (CBM) probes as the main means of assessment. Other methods of assessment included standardized achievement tests, school reports, and pre- and postcurriculum- based assessment probes. The CBM probes for all students were sensitive to the effects of the interventions, although there was a great deal of variability in the CBM reading probes and little correspondence across methods of assessment. The results indicate that the two Direct Instruction programs …

An Analysis Of Nine K-12 School Districts That Have Established Membership With The Coalition Of Essential Schools, Shari A. Peters Kitchen

Dissertations

In the late 1970s, Ted Sizer, professor of education at Brown University, and a team of researchers traveled the country visiting dozens of secondary schools. The purpose of these visits was to understand the American high school by observing it firsthand. Sizer reported his findings in 1984 in Horace's Compromise: The Dilemma of the American High School.

In response to the compromises raised in Horace's Compromise, 12 schools volunteered to become the Coalition of Essential Schools. The Coalition rests on a set of nine Common Principles, which include intellectual rigor, simple and universal goals, personalized school, graduation by exhibitions …

The Relationship Between Selected Environmental Variables And Attrition, Persistence, And Academic Success Of Majority And Minority College Students, Carole J. Woolford-Hunt

Dissertations

Research indicates that college student persistence, attrition, and success is related to the student’s ability to gain academic and social integration into the university community. This theory has guided researchers to explore either the academic or social factors that promote integration. Under the umbrella of social integration exists the underresearched category of environmental factors.

The overall purpose of this study was to identify selected environmental factors that affect minority and majority students’ persistence and success rates in a Midwestern state-run university. The environmental variables of size of college within a larger university, residential versus nonresidential nature of colleges within a …
