Recent research into students' reasoning about variation refers specifically to notions of distribution that emerge. This paper reports on research where written responses, from tertiary introductory statistics students, were coded according to the level of consideration of variation. A hierarchy of reasoning about distribution is proposed, based on the(More)
During a research project investigating understanding of variation students in a tertiary level introductory statistics course completed a questionnaire prior to, and at the end of, the course. This paper reports on interviews of selected students designed to determine whether more information could be gathered, and to identify those teaching and learning(More)
The complementarity determining region III of the rearranged iinimi-noglobulin heavy chain gene has been the target for tumor-specific PCR assays for the detection and follow-up of B-cell malignancies. Previously, these assays have relied on gel-based end point data collection methods (i.e., band densitometry) and, thus, have provided at best a semiquanti(More)
This paper reports one recent study that was part of a project investigating tertiary students' understanding of variation. These students completed a questionnaire prior to, and at the end of, an introductory statistics course and this paper focuses on interviews of selected students designed to determine whether more information could have been gathered(More)
The development of a Profile of Statistical Understanding is aimed at providing a tool to assist educators to identify what 'can be' expected of students rather than what 'should be'. This profile needs to cover all basic areas of statistics in such a way that specific profiles will identify what to expect of graduating secondary students with respect to(More)
Gene transfer into hematopoietic stem cells by cell-free virions is a goal for gene therapy of hematolymphoid disorders. Because the hematopoietic microenvironment provided by the stroma is required for stem cell maintenance both in vivo and in vitro, we reasoned that cell-free transduction of bone marrow cells (BMC) may be aided by stromal support. We used(More)
There has been an increasing focus in recent years on theoretical frameworks to describe cognitive development of statistical concepts. There is now a need to encourage the use of these frameworks to inform practice in the teaching and learning of statistics. This paper focuses on frameworks that describe the levels of cognitive development of the concept(More)
