Bar graphs and histograms are core statistical tools that are widely used in statistical practice and commonly taught in classrooms. Despite their importance and the instructional time devoted to them, many students demonstrate misunderstandings when asked to read and interpret bar graphs and histograms. Much of the research that has been…

We present our design for a cell biology course to integrate content with scientific practices, specifically data interpretation and model-based reasoning. A 2-year research project within this course allowed us to understand how students interpret authentic biological data in this setting. Through analysis of written work, we measured the extent…

An evaluation system that is designed to support and improve teacher practice--rather than simply to assess and manage teacher performance--would have as its foundation effective and reliable processes to observe classroom practice and give teachers useful feedback. Such an improvement-focused evaluation system should be aligned with and…

In this paper, I describe preliminary work on a new research project in learning analytics at Arizona State University. In conjunction with an innovative remedial mathematics course using Khan Academy and student coaches, this study seeks to measure the effectiveness of visualized data in assisting student coaches as they help remedial math…

The central goal of this study was to characterize major patterns of reasoning exhibited by college chemistry students when analyzing and interpreting chemical data. Using a case study approach, we investigated how a representative student used chemical models to explain patterns in the data based on structure-property relationships. Our results…

To address the needs and interests of primary stakeholders in a writing program, this article presents a model of "grassroots" assessment that involves instructors from all ranks as well as students in the development, facilitation, and interpretation of assessment results. The authors describe two assessment plans that measured student…

In this article we explore educators' use of Jean Piaget's theories concerning cognitive development to refute proposed social studies standards in Arizona. We describe the work of Piaget as well as the National Association for the Education of Young Children's developmentally appropriate practices as they apply to primary-grade children's…

The usefulness of state-by-state comparisons and other educational indicators is discussed in this paper, which seeks to improve report writing and data presentation skills. The first part offers an example of a policy report that uses key education indicators to describe the Arizona education system. Tables and data interpretation describe the…
