Green Chemistry As A Tool For Understanding The Toxic Substances Control Act: A Lecture Module For Undergraduate Students, Molly R. Blessing
Green Chemistry As A Tool For Understanding The Toxic Substances Control Act: A Lecture Module For Undergraduate Students, Molly R. Blessing
Honors Scholar Theses
The Toxic Substances Control Act (TSCA) is the central form of chemical regulation existent in the United States today, yet scientists are often unaware or uncertain of its provisions. Violations of TSCA by unknowing chemists set industry and government unnecessarily at odds. A lecture on TSCA was developed for undergraduate students that uses the concept of green chemistry to promote interest and incentivize learning. Green chemistry methods are cleaner and less wasteful than traditional chemical ones, and many companies using them are at the forefront of technological innovation. The lecture explains both green chemistry and TSCA, includes company case studies, …

Middle School Student Perceptions Of Homework In Mathematics, Camille M. Thomas
Honors Scholar Theses
Homework has been a source of debate in schools for the past several decades and will continue to be an important topic in the future. It is a traditional part of education but some debate its importance in the classroom. This study explored student perception of homework and their reported performance in middle school mathematics. The research questions focused on student attitudes about homework, the relationship of students’ self-efficacy and support resources to their homework completion, and the relationship of students’ general level of achievement in mathematics to their attitudes about homework. The study involved a survey of 230 middle …
Supporting Student Justification In Middle School Mathematics Classrooms: Teachers' Work To Create A Context For Justificaiton, Megan Staples
Supporting Student Justification In Middle School Mathematics Classrooms: Teachers' Work To Create A Context For Justificaiton, Megan Staples
CRME Publications
Justification is an important disciplinary and learning practice. Despite a growing knowledge base regarding how teachers orchestrate mathematical discussions, few analyses have considered the orchestration of specific disciplinary practices such as justification. Using classroom video data from the JAGUAR project, we analyze two instantiations of extensive student justification in seventh-grade classrooms and document each teacher’s pedagogical approach that supported students’ engagement in this practice. We argue that, although there was overlap in their pedagogical repertoires, the teachers created a context for student justification in two unique ways. We document the similarities and differences in their approaches, including the nature of …

In this article, two researchers investigate the oxygen, or lack of, in small bays of Long Island Sound.
Bar Graphs & Baselines: Student Perceptions Of Distortions In Real World Graphs, Robert K. Janes Iii
Bar Graphs & Baselines: Student Perceptions Of Distortions In Real World Graphs, Robert K. Janes Iii
Honors Scholar Theses
It is important for every educated member of our society to be able to read, comprehend, and interpret graphs. To that end, the National Council of Teachers of Mathematics (NCTM) and the Common Core State Standards have endorsed a kindergarten through eighth-grade mathematics curriculum that is rich in data analysis and graphical literacy skills. These skills are important, as graphs in the public sphere may include certain features that can cause misperceptions of the data. Such features may be intentional or unintentional and can include non-zero baselines, representing data with extra dimensions, stretching and shrinking graphics, not displaying outliers, and …
Getting To The "Why": Teacher Practices That Support Mathematically Sound Student Justifications, Briana Hennessy
Getting To The "Why": Teacher Practices That Support Mathematically Sound Student Justifications, Briana Hennessy
Honors Scholar Theses
Though the mathematical and education communities both value justification and argumentation in the middle grades classroom, teachers have historically found these practices difficult to support. This article discusses teaching practices that are associated with high levels of mathematically acceptable argumentation by students. Data were collected on seven committed teachers who explored justification and then implemented the same justification task over two years. Thus, the data reflected fourteen different implementations of the same task, allowing us to compare lessons directly. The findings describe how teachers’ Focusing Students’ Mathematics and Providing Scaffolding Questions are consistently associated with high levels of justification, while …

Kindergarten Mathematics: An Observational Study Of Learning Centers In Diverse School Settings, Juliana Macswan
Honors Scholar Theses
This qualitative research study investigated how centers were used in kindergarten math classes and students’ mathematical engagement and authority within centers in five classes field-testing the Project M2: Mentoring Young Mathematicians measurement and geometry units. Data were collected from three observations in each of the five classes as well as observations from trained professional development staff working on the field-test and teacher exit interviews. Results indicated that in four of the five classes two-thirds of the centers related to the unit objectives and students spent over 90% of time in unit related centers. There were a variety of …

Undergraduate Engineering Students' Understanding Of Heat, Temperature, And Radiation, Katharyn E.K. Nottis, Michael Prince, Margot Vigeant, Sarah Nelson, Kathryn Hartsock
Undergraduate Engineering Students' Understanding Of Heat, Temperature, And Radiation, Katharyn E.K. Nottis, Michael Prince, Margot Vigeant, Sarah Nelson, Kathryn Hartsock
NERA Conference Proceedings 2009
Difficulty understanding heat and temperature concepts has been recognized in engineering education. Confusion has been shown to persist after instruction. The purpose of this study was to determine whether undergraduate engineering students’ knowledge of four heat transfer concept areas significantly changed with instruction and whether this varied by major and GPA. Two hundred twenty-eight undergraduate engineering students from six institutions were assessed prior to and after instruction. Results showed significant improvement in most concept areas but mean scores were below mastery. Previously documented misconceptions persisted after instruction. Significant differences were found by major and GPA. Suggestions for future research provided.
The Effect Of Mathematics Self-Efficacy On Mathematics Achievement Of High School Students, Xing Liu, Hari Koirala
The Effect Of Mathematics Self-Efficacy On Mathematics Achievement Of High School Students, Xing Liu, Hari Koirala
NERA Conference Proceedings 2009
The purpose of this study was to investigate the relationship between mathematics self-efficacy and mathematics achievement of high school sophomores across the United States. Using regression analysis for complex sample survey data from the Educational Longitudinal Study of 2002 (ELS, 2002) (n = 11726), the current study indicated that mathematics self-efficacy and mathematics achievement were positively related, and mathematics self-efficacy was a significantly positive predictor of mathematics achievement. Results from this study, which is generalizable to the population of approximately three million high school sophomores, suggest that mathematics self-efficacy of high school students should be promoted to increase their achievement.

Improving Automaticity With Basic Addition Facts: Do Taped Problems Work Faster Than Cover, Copy, Compare?, James Cressey, Kristin Ezbicki
Improving Automaticity With Basic Addition Facts: Do Taped Problems Work Faster Than Cover, Copy, Compare?, James Cressey, Kristin Ezbicki
NERA Conference Proceedings 2008
This small pilot study compared the effectiveness of two interventions to improve automaticity with basic addition facts: Taped Problems (TP) and Cover, Copy, Compare (CCC), in students aged 6-10. Automaticity was measured using Mathematics Curriculum-Based Measurement (M-CBM) at pretest, after 10 days, and after 20 days of intervention. Our hypothesis was that the TP group will gain higher levels of automaticity more quickly than the CCC and control groups. However, when gain scores were compared, no significant differences were found between groups. Limitations to the study include low treatment integrity and a short duration of intervention.
A Case Study Of Teachers' Mathematics Content Knowledge And Attitudes Toward Mathematics And Teaching, Brian R. Evans
A Case Study Of Teachers' Mathematics Content Knowledge And Attitudes Toward Mathematics And Teaching, Brian R. Evans
NERA Conference Proceedings 2008
This study intended to measure teacher mathematical content knowledge both before and after the first year of teaching and taking graduate teacher education courses in the Teach for America (TFA) program, as well as measure attitudes toward mathematics and teaching both before and after TFA teachers’ first year. There was a significant increase in both mathematical content knowledge and attitudes toward mathematics over the TFA teachers’ first year teaching. Additionally, several significant correlations were found between attitudes toward mathematics and content knowledge. Finally, after a year of teaching, TFA teachers had significantly better attitudes toward mathematics and teaching than neutral.
The Effect Of Direct Instruction Versus Discovery Learning On The Understanding Of Science Lessons By Second Grade Students, Marisa T. Cohen
The Effect Of Direct Instruction Versus Discovery Learning On The Understanding Of Science Lessons By Second Grade Students, Marisa T. Cohen
NERA Conference Proceedings 2008
This study examined the effectiveness of discovery learning and direct instruction in a diverse second grade classroom. An assessment test and transfer task were given to students to examine which method of instruction enabled the students to grasp the content of a science lesson to a greater extent. Results demonstrated that students in the direct instruction group scored higher on the assessment test and completed the transfer task at a faster pace; however, this was not statistically significant. Results also suggest that a mixture of instructional styles would serve to effectively disseminate information, as well as motivate students to learn.

Addressing Misconceptions About Heat Transfer In Undergraduate Chemical Engineering Instruction, Katharyn E. K. Nottis, Michael J. Prince, Margot A. Vigeant
NERA Conference Proceedings 2008
Understanding heat, energy and temperature can be difficult. Misconceptions about heat transfer have been found to persist, even after instruction. New instructional methods are needed to address them. This pilot study examined whether researcher-developed, inquiry-based activities could increase conceptual understanding of heat transfer. Twenty-two undergraduate chemical engineering students were assessed before and after instruction with inquiry-based activities. Participants had significantly higher scores on the post-test. An examination of assessment questions revealed substantial improvement on questions closely related to activities. However, participants had difficulty applying concepts in new and related contexts. Educational implications and suggestions for future research will be discussed.

Promoting Student Collaboration In A Detracked, Heterogeneous Secondary Mathematics Classroom, Megan Staples
CRME Publications
Detracking and heterogeneous groupwork are two educational practices that have been shown to have promise for affording all students needed learning opportunities to develop mathematical proficiency. However, teachers face significant pedagogical challenges in organizing productive groupwork in these settings. This study offers an analysis of one teacher’s role in creating a classroom system that supported student collaboration within groups in a detracked, heterogeneous geometry classroom. The analysis focuses on four categories of the teacher’s work that created a set of affordances to support within group collaborative practices and links the teacher’s work with principles of complex systems.
