An Account Of Novice Phylogenetic Tree Construction From The Problem-Solving Research Tradition, Terrance E. Brisbin

Dissertations

Both the content and strategic knowledge used in phylogenetic tree construction are described to account for novice performance. A review of the literature is used to place this research with respect to studies in: problem solving studies (both expert, and novice), the history and practice of evolutionary systematics, and the teaching of evolution. The computer-based problem-solving environment is discussed along with model problems used for the research.

Each of the five research problems consists of an encoded matrix containing phylogenetic data organized by taxa and characters. Twelve participants (high school students) volunteered to solve the research problems, on their own …

The Benefits Of Observational Learning On The Mathematics Achievement Of Fourth Grade Students Involved In Peer Tutoring Sessions, Trisha R. Parish

Masters Theses

Many students struggle with mathematical concepts and operations. This leads educators to search for the most effective and efficient means of improving their academic performance. The present investigation sought to determine if a triadic peer-tutoring program would increase the acquisition of basic multiplication facts for fourth grade students. Secondly, this investigation assessed the extent to which students would benefit from observational learning opportunities within the peer tutoring sessions. A multiple baseline design across two peer-tutoring triads was utilized with student performance being assessed by measuring responses to flashcard presentations and completion of three types of mathematics probes. The first type …

An Investigation Into Relationships Between Alternative Assessment And Pre-Service Elementary Teachers’ Beliefs About Mathematics, David Charles Coffey

Dissertations

The purpose of this study was to examine how including alternative assessments in a reform-based mathematics course affects pre-service teachers’ mathematical beliefs. A single section of a mathematics course designed for elementary education majors that employed three different alternative assessments was the setting for the study.

A pre- and post-belief survey completed by students enrolled in the section under study represented the first level of data collection and analysis. The results of the pre-belief survey guided the selection of seven informants from the section and provided belief statements for the informants to verify during subsequent interviews. Based on the data …
