Mingus, Tabitha T. Y.; Grassl, Richard M.; Diaz, Ricardo; Andrew, Lane; Parker, Frieda – Mathematics Teacher, 2010

This article analyzes the challenge of counting the number of rectangles of all sizes in the n-tableau and to provide a combinatorial reason for the answer. The authors present a solution on enumerating rectangles in the n-tableau using Grassl and Mingus results. The authors demonstrate their conjecture for the n-tableau and attempt to apply their…

Grassl, Wolfgang – Journal of Catholic Higher Education, 2012

By virtue of its divine vocation, Catholic business education must be mission driven. In reality, however, mission drift and failure to maintain distinctiveness are widespread among Catholic business schools (CBS). Many believe that a trade-off between academic quality and Catholicity is unavoidable, and opt for accommodating the expectations of…

Grassl, Rebecca – ProQuest LLC, 2010

Mathematics competency continues to limit the success of many students and prevents their completion of a postsecondary degree, which ultimately prevents access to education, jobs, and upward social mobility. Furthermore, many postsecondary institutions admit students who do not meet the institution's mathematics proficiency requirements and then…

Medina, Elsa; Grassl, Richard; Fay-Zenk, Mary – Mathematics Teaching in the Middle School, 2014

While some students are enjoying days at the park or at the beach, forty middle school students are in a classroom solving challenging mathematics problems. The second Math Camp for middle school students was offered in 2013 at a western university for students from local school districts. For three days, these students met from 10 a.m. to 3 p.m.…

Morrow, Lorna J., Ed.; Kenney, Margaret J., Ed. – 1998

This 1998 yearbook aims to stimulate and answer questions that all educators of mathematics need to consider to adapt school mathematics for the 21st century. The papers included in this book cover a wide variety of topics, including student-invented algorithms, the assessment of such algorithms, algorithms from history and other cultures, ways…

Sheffield, Linda Jensen, Ed. – 1999

This book, written on the recommendation of the Task Force on Mathematically Promising Students, investigates issues involving the development of promising mathematics students. Recommendations are made concerning topics such as the definition of promising students; the identification of such students; appropriate curriculum, instruction, and…

Ansorge, Ulrich; Kiefer, Marcus; Khalid, Shah; Grassl, Sylvia; Konig, Peter – Cognition, 2010

In the current study, we tested the embodied cognition theory (ECT). The ECT postulates mandatory sensorimotor processing of words when accessing their meaning. We test that prediction by investigating whether invisible (i.e., subliminal) spatial words activate responses based on their long-term and short-term meaning. Masking of the words is used…

Powers, Robert A.; Craviotto, Cathleen; Grassl, Richard M. – International Journal of Mathematical Education in Science and Technology, 2010

Many undergraduate students have difficulty writing mathematical proofs even though this skill is important for the development of future teachers and those who may be involved in instruction or training as a graduate student or supervisor. In addition, research indicates that mathematics majors and secondary education mathematics majors possess…

Grassl, R.; Mingus, T. T. Y. – International Journal of Mathematical Education in Science and Technology, 2007

Experiences in designing and teaching a reformed abstract algebra course are described. This effort was partially a result of a five year statewide National Science Foundation (NSF) grant entitled the Rocky Mountain Teacher Enhancement Collaborative. The major thrust of this grant was to implement reform in core mathematics courses that would…

Powers, Robert A.; Allison, Dean E.; Grassl, Richard M. – International Journal for Technology in Mathematics Education, 2005

This study investigated the impact of the TI-92 handheld Computer Algebra System (CAS) on student achievement in a discrete mathematics course. Specifically, the researchers examined the differences between a CAS section and a control section of discrete mathematics on students' in-class examinations. Additionally, they analysed student approaches…

Grassl, Richard – Mathematics Teacher, 1996

Presents an activity that involves drawing pictures to collect data, conjecturing a recurrence relation, and solving the relation using geometric series and partial fractions. (MKR)

Grassl, Richard M.; Mingus, Tabitha T. Y. – International Journal of Mathematical Education in Science and Technology, 2002

This article presents teaching ideas designed to support the belief that students at all levels (preservice teachers, majors, secondary and elementary students) need exposure to non-routine problems that illustrate the effective use of technology in their resolution. Such use provides students with rapid and accurate data collection, leading them…

Mingus, Tabitha; Grassl, Richard – Mathematics and Computer Education, 1997

Secondary mathematics teachers participated in a problem-solving course in which technology became a means to develop as teachers and as problem solvers. Findings indicate a delineation between technical competence and metatechnology--thinking about how and when to apply technology to particular problems. (PVD)

Mingus, Tabitha T. Y.; Grassl, Richard M. – School Science and Mathematics, 1999

Describes the study of backgrounds, beliefs, and attitudes of teachers (n=51) about proofs. Explores four issues: (1) preservice teachers' experiences/exposure to proof; (2) their beliefs about what constitutes proof; (3) the role of proof in mathematics; and (4) their beliefs about when proof should be introduced in K-12 math classes. Discusses…
