The Effects Of Standards-Based Grading On Student Performance In Algebra 2, Rachel Beth Rosales

Dissertations

The use of standards-based grading in American public schools is increasing, offering students, parents, and teachers a new way of measuring and communicating about student achievement and performance. Parents indicate an appreciation for this method of grading, and students at the elementary grades (K-6) have improved standardized test scores in reading and math as a result of its implementation. This study seeks to determine whether standards-based grading has the same effect on students at the high school level (grades 9-12) by comparing end-of-course test scores and posttest scores of Algebra 2 students enrolled in a standards-based graded classroom with to …

Studies In Analytical Chemistry And Chemical Education. Part 1: Characterization Of Complex Organics By Raman Spectroscopy And Gas Chromatography. Part 2: Differential Item Functioning On Multiple-Choice General Chemistry Assessments, Lisa Kay Kendhammer

Theses and Dissertations

PART 1: CHARACTERIZATION OF COMPLEX ORGANICS BY RAMAN SPECTROSCOPY AND GAS CHROMATOGRAPHY.

The analytical chemistry component of this thesis focused on instrumentation and methods to address challenges in art conservation, particularly the identification, quantitation, and reactivity of a set of representative varnishes and their degradation products. Methods for characterizing varnishes are of great interest to art conservators to restore art work more accurately. A database was created as a means to identify and quantify the composition of aged varnishes. Fourier Transform (FT)-Raman Spectroscopy was used to study common organic acids found in varnishes. The database included nine short-chain carboxylic acids, …

Teaching And Assessing Programming Fundamentals For Non Majors With Visual Programming, William L. Honig

Computer Science: Faculty Publications and Other Works

Visual programming tools and mobile device applications are a natural tool to engage university students; but, are they effective in teaching quantitative thinking skills to non computer science majors? Answering this question can be based on careful assessment of the learning outcomes.

This paper reports the results from teaching over 100 students mobile app development with App Inventor in a university core course. Results were measured using an assessment process motivated by Bloom's Taxonomy that included student self assessment, ratings by instructors, and comparisons of the two results. The categories in the assessment were mapped to specific levels of skills …

Mapcores 2012-2013 Assessment Report, Kristen Nairn, Pamela L. Bacon, Jim Crumley, Lynn Ziegler

MapCores Faculty Publications

This is a report showing the assessment results for the MapCores (MAthematics, Physics, COmputer science REsearch Scholars) program at the College of Saint Benedict. Started in 2009, MapCores is a cohort-based program designed to increase women's interest and achievement in mathematics, physics, computer science and engineering. The report was submitted for the National Science Foundation grant number 0965705.

Measuring Habits Of Mind: Toward A Prompt-Less Instrument For Assessing Quantitative Literacy, Stuart Boersma, Dominic Klyve

Numeracy

In this study, we offer a new “prompt-less” instrument for measuring students’ habits of mind in the field of quantitative literacy. The instrument consists of a series of questions about a newspaper article the students read. The questions do not explicitly solicit quantitative information; students’ habit of mind is assessed by their use of quantitative reasoning even when it is not asked for. Students’ answers were graded according to a modified version of the Quantitative Literacy Assessment Rubric (QLAR) published in this journal (vol. 4, issue 2). We applied the instrument and rubric to assess pre- and post-intervention habits of …

Using A Media-Article Approach To Quantitative Reasoning As An Honors Course: An Exploratory Study, Stuart Boersma, Dominic Klyve

Numeracy

In this study, we investigate student performance on a basic skills assessment of percentages and ratios in two cohorts of students: the general (non-STEM) student body (cohort G) and (non-STEM) honors students (cohort H). Both cohorts used a media-article approach to the study of quantitative reasoning. A pre- and a post-intervention assessment were administered with a two-week intervention period consisting of critical analyses of the use of percentages and ratios in media articles. Using non-parametric techniques, no statistically significant improvement was measured in cohort G while cohort H students showed statistically significant improvement on several items.

Metr 200: Weather And Climate—A Peer Review Of Teaching Project Benchmark Portfolio, Matthew S. Van Den Broeke

UNL Faculty Course Portfolios

This benchmark portfolio is meant to be an assessment of how well the objectives of METR 200 (Weather and Climate) are being attained by students in several classifications of academic major. Students from a wide range of backgrounds enroll in this course as a general science elective, and for many, it will be the only science course taken in college. Thus, it is important that course material be sufficiently accessible for all students, while providing meaningful information which will be applicable by students of all backgrounds once they leave the course. In this portfolio, an analysis will be presented showing …

Chem 109: General Chemistry I—A Peer Review Of Teaching Project Benchmark Portfolio, Eric D. Dodds

UNL Faculty Course Portfolios

This portfolio has been developed for CHEM 109: General Chemistry I. The course is the first of a freshman level two semester sequence in General Chemistry taken by students with majors in a wide variety of technical and scientific disciplines. CHEM 109 is a high enrollment class, with class sizes for individual sections nearing 200 students. The development of this portfolio was conducted with the following objectives: 1. Clearly identify, justify, and codify the major learning objectives for this course, 2. Describe and rationalize the course structure and learning assessment methods, 3. Analyze and reflect on student achievement in the …

Effective Methods Of Formative Assessment, Chelse Rae Bugg

Online Theses and Dissertations

The purpose of this research is to explore the implementation of formative assessment in the mathematics classroom. Formative assessment is considered to be any data-driven activity that an educator uses to help guide and improve instruction. While there is an abundance of research that concludes that formative assessment does indeed improve student achievement, practical methods of implementation are not thoroughly discussed. To partially determine which methods of formative assessment most positively impact student achievement, a study was conducted at Lafayette High School. The researcher compared two popular methods of formative assessment: daily exit slips and unit probing (pre-, middle-, and …

Using Formative Assessment To Enhance Student Performance On Geometric Proof Writing, Benjamin Hargrave

LSU Master's Theses

The purpose of this research is to uncover best practices to create competent proof writers. Studies have shown the best setting to do this is in the high school geometry classroom. Throughout a yearlong study of geometry, students were exposed to theorems and their demonstrations. Despite constant exposure, students were still unable to produce their own proof of propositions. The questions then became how can an educator provide critical feedback that encourages student reasoning and develops logical argumentation skills? With the goal in mind, twenty-five students enrolled in a geometry course at Baton Rouge High School in Baton Rouge, Louisiana …
