The purpose of this study was to explore how students with high- and low-prior-knowledge employed multiple representations in argumentation evaluation and generation tasks. The argumentation performance and eye-movement behaviors of 96 college students in these tasks were investigated. The number of participants who proposed complex argumentation…

This study focuses on how students in different postsecondary mathematics courses perform on domain and range tasks regarding graphs of functions. Students often seem to focus on notable aspects of a graph and fail to see the graph in its entirety. Many students struggled with piecewise functions, especially those involving horizontal segments.…

Communicating climate information is challenging due to the interdisciplinary nature of the topic along with compounding cognitive and affective learning challenges. Graphs are a common representation used by scientists to communicate evidence of climate change. However, it is important to identify how and why individuals on the continuum of…

With the advances in mobile network technology, the use of portable devices and mobile networks for learning is not limited by time and space. Such use, in combination with appropriate learning strategies, can achieve a better effect. Despite the effectiveness of mobile learning, students' learning direction, progress, and achievement may differ.…

Problem solving in the field of quantitative composition of solutions (QCS), expressed as mass share and molar concentration, is essential for chemistry students. Since successful chemistry education is based on different mathematical contents, it is important to be proficient in both mathematical and chemistry concepts as well as interconnections…

The purpose of this study is to investigate the effect of using the Geometer's Sketchpad software in the teaching and learning of graph functions among Form Six (Grade 12) students in a Malaysian secondary school. This study utilized a quasi-experimental design using intact group of students from two classes in an urban secondary school. Two…

A reporting and study format for the investigation of university student retention is presented. Student progression and loss is shown graphically and in tabular form to enable ready comprehension and encourage data exploration. Data obtained at Virginia Commonwealth University for 1977-80 are used as illustration. Two ways of viewing student…

A new statistical measure termed the Composite Indicator of Changes (CIC) reflects overall changes in average salaries and wages paid by public school systems in much the same way that the Dow-Jones averages reflect price changes in the stock market. The CIC is useful for comparing salary trends among various categories of personnel, among…

The Composite Indicator of Changes (CIC) in average salaries and wages paid by public school systems is designed to reflect overall changes, to compare salary trends among various categories of personnel, and to analyze salary trends in an individual school system and among groups of school systems. Annual updates of the CIC are computed from data…

This report provides data to evaluate salary and wage trends in education. The statistical measure used to gauge and compare changes in salaries and wages paid by school systems is the Composite Indicator of Changes (CIC). This measure is designed to reflect changes in much the same way as the Dow Jones Average or the Standard and Poor's Index.…
