Guidelines To Avoid Typical Difficulties According To The Rubric For Experimental Design (Red), Annwesa Dasgupta, Nancy Pelaez

PIBERG Publications

Experimental design is an important component of undergraduate biology education as it generates knowledge of biology. Despite its importance, there is limited information about what students actually learn from designing experiments. Dasgupta et al (2014) reported on the development and validation of a Rubric for Experimental Design (RED), informed by a literature review and empirical analysis of thousands of undergraduate biology students’ responses to three published assessments. The RED is a useful probe for five major areas of experimental design abilities: the variable properties of an experimental subject; the manipulated variables; measurement of outcomes; accounting for variability; and the scope …

Understanding Correlation: Factors That Affect The Size Of R, Laura D. Goodwin, Nancy L. Leech

Nancy Leech

The authors describe and illustrate 6 factors that affect the size of a Pearson correlation: (a) the amount of variability in the data, (b) differences in the shapes of the 2 distributions, (c) lack of linearity, (d) the presence of 1 or more "outliers," (e) characteristics of the sample, and (f) measurement error. Also discussed are ways to determine whether these factors are likely affecting the correlation, as well as ways to estimate the size of the influence or reduce the influence of each.

The Effect Of Robotics On Test Scores And Involvement In Stem Fields, Nicole Costa

Undergraduate Research

There is an under-representation of women in science, technology, engineering, and mathematics (STEM) fields that influences society’s perception of women’s abilities in mathematics and science. This study researches the implications of participation in robotics on girls’ achievement and perceptions. Specifically studying the population at the high school of Mount Saint Joseph Academy, it searches for a correlation between membership on the Firebirds Robotics Team and higher GPA scores, SAT scores, and likelihood of having a major in STEM. Data was collected on robotics and non-robotics alumni by using a survey. Various significance tests including t-tests, signed rank tests, and paired …

The Correlation Between Student/Instructor Rapports, Student Perceptions Of Instructor Effectiveness, And Course Grade Expectations, Erin Yezbick

Doctoral Dissertations and Projects

The researcher attempted to determine if a correlation exists between student/instructor rapport, student perceptions of instructor effectiveness, and course grade expectations for freshman general education courses at a career college in the Great Lakes Region of the United States. Previous studies have determined that rapport affects motivation (Bergström, 2010; Frisby, Berger, Burchett, Herovic, & Strawser, 2014; Legg & Wilson, 2009), perceptions of teacher effectiveness (Giles, 2011; Kozub, 2010), and evaluation scores (Barth, 2008; Kowai-Bell, Guadango, Little, & Ballew, 2012). The researcher asked the following research questions: Is there a relationship between student/instructor rapport, as measured by the Professor-Student Rapport Scale …

Hist 340: American Legal History—A Peer Review Of Teaching Project Inquiry Portfolio, Katrina Jagodinsky

UNL Faculty Course Portfolios

This inquiry portfolio measures the success of revisions made to HIST 340: American Legal History after a previous benchmark portfolio revealed a number of problems in communicating to students the importance and meaning of the course objectives, in correlating assessments to the final grade, and in documenting student learning and quality of instruction. The findings, outlined below, indicate that identifying a clear course theme; more strongly aligning readings, assessments, and discussions to course objectives; and restructuring the verbal and written analysis of readings dramatically improved students’ performance and satisfaction. Measures used include formal and informal student evaluations of instruction, formal …

Characteristics Of Adult General Education Learners And Courses: A Correlational Study On The Elements Of Success, Daniel Jennings Stackhouse

Theses and Dissertations

The purpose of this study was to determine if a correlation exists among characteristics common to successful adult career and technical students in the traditional classroom setting, the online mode of instruction, and a hybrid of the traditional and distance mode of instructional delivery. A gap in the literature exists, resulting in a lack of knowledge specific to the reasons for success or failure of these adult career and technical students, specifically in relation to mode of instructional delivery: traditional classroom, online, or a hybrid of both.

This study is a quantitative correlation study of explanatory and predictive design using …
