This study investigated the effects of applying mathematical modeling on revising students' preconception of the process of optimizing area enclosed by a string of a fixed length. A group of 28 high school pre-calculus students were immersed in modeling activity that included direct measurements, data collecting, and formulating algebraic…

Data collection and analysis as a cybernetic aspect of a Learning Assistance Center (LAC) is discussed. Using the LAC at California State University Long Beach (CSULB) as a model, the LAC is defined as a support, delivery, and referral service for the entire campus community. A LAC is held accountable to itself and its users through a cybernetics…

Statistical laboratory exercises designed to promote better understanding of statistical concepts in an introductory non-calculus statistics course are illustrated. The exercises make extensive use of data that are individually generated by tables of random digits or by computer. (MN)

In this article, the authors demonstrate how a simple math lab incorporating monthly height measurements can address multiple science and mathematics standards such as collecting, organizing, and describing data in context; drawing conclusions; and making hypotheses from these data. Although the yearlong math lab can be accomplished in either the…

This study investigated the lived experiences of a group of students and their teacher as they negotiated learning and teaching during a sixth-grade exploratory music technology course taught in a music technology lab. Taking a qualitative and naturalistic approach, I sought to understand the challenges, issues, and successes experienced by the…
