A math cognitive tutor (MCT) system widely used throughout the U.S. was adapted for use in Chilean middle schools. The curriculum requires large changes in pedagogy, including the use of computers for individual students to progress through an extended Algebra I program. Students enrolled in schools which adopted the MCT significantly improved their math test scores as compared to control group...

Relevant Education in Math and Science (REMS) is a university-led STEM outreach program designed to use real-world industrial engineering problems to make 5 – 12 grade math and science fun and meaningful for students. In this work, we present the nine current engineering lab activities, developed in both in-lab and on-line format consisting of three different real-world contexts: competitive ma...

Mathematics education in the future faces enormous opportunities from the availability of ubiquitous digital networks, from innovative educational approaches based on theories of collaborative learning and from rich resources for interactive, online, dynamic math exploration. The fact that more and more teachers and students are learning online—with distance education, online masters programs, ...

The ability to compute, problem solve, and apply concepts and skills in mathematics influences multiple decisions in our lives. The National Research Council (1989) reported that mathematics is especially evident in our technology-rich society, where number sense and problem solving skills have increased the importance and demands of advanced levels of proficiency. However, mathematics is often...

Understanding an arithmetic operation implies, at minimum, knowing the direction of effects that the operation produces. However, many children and adults, even those who execute arithmetic procedures correctly, may lack this knowledge on some operations and types of numbers. To test this hypothesis, we presented pre-service teachers (Study 1), middle school students (Study 2), and math and sci...

In a world filled with big data, mathematical models, and statistics, the development of strong quantitative skills is becoming increasingly critical for modern biologists. Teachers in this field must understand how students acquire quantitative skills and explore barriers experienced by students when developing these skills. In this study, we examine the interrelationships among gender, grit, ...

This work reports the results of a study whose objective was to analyze didactic-mathematical knowledge future mathematics teachers when solving an unequal game. The sample made up 24 professors from Chilean university. Task-based interviews were used collect information. show that have adequate intuitive ideas about expected value, prioritize classical approach solve situations and determine i...

The purpose of this research was to contribute to a better understanding of how to enhance pre-service teachers’ knowledge of mathematics teaching through Model, Strategy, and Application (MSA). 153 pre-service teachers from six math methods courses (K-8) at two universities participated in this study. Both qualitative and quantitative methods were used to measure teacher learning and understan...
