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 …
