    Abstract:
    Coordinate graphs of time-series data have been significant in the history of statistical graphing and in recent school mathematics curricula. A survey task to construct a graph to represent data about temperature change over time was administered to 133 students in Grades 3, 5, 7, and 9. Four response levels described the degree to which students transformed a table of data into a coordinate graph. "Nonstatistical" responses did not display the data, showing either the context or a graph form only. "Single Aspect" responses showed data along a single dimension, either in a table of corresponding values, or a graph of a single variable. "Inadequate Coordinate" responses showed bivariate data in two-dimensional space but inadequately showed either spatial variation or correspondence of values. "Appropriate Coordinate" graphs displayed both correspondence and variation of values along ordered axes, either as a bar graph of discrete values or as a line graph of continuous variation. These levels of coordinate graph production were then related to levels of response obtained by the same students on two other survey tasks: one involving speculative data generation from a verbal statement of covariation, and the other involving verbal and numerical graph interpretation from a coordinate scattergraph. Features of graphical representations that may prompt student development at different levels are discussed. (Contains 8 figures and 2 tables.)

    Abstract:
    We describe the design and iterative implementation of a learning progession for supporting statistical reasoning as students construct data and model chance. From a disciplinary perspective, the learning trajectory is informed by the history of statistics, in which concepts of distribution and variation first arose as accounts of the structure inherent in the variability of measurements. Hence, students were introduced to variability as they repeatedly measured and attribute (most often, length), and then developed statistics as ways of describing "true" measure and precision. Both of these developments have historic parallels, and the intricate relation of measure and data are also key components of ongoing professional practice (see Hall et al., this symposium). From a learning perspective, the learning trajectory reflects a commitment to several related principles: (a) constituting a learning progession as encounters with a series of problematics; (b) representational fluency and meta-repesentational competence as constituents of conceptual development in a discipline; (c) invented measures as grounding students' understanding of statistics and (d) an agentive perspective for orienting student activity, according to which distribution of measures emerges as a result of the collective activity of measurer-agents. Instructional design and assessment design (see Wilson et al., this symposium) were developed in tandem, so that what we took as evidence for the instructional design was subjected to test a a model of assessment, resulting in revision to each.

    Abstract:
    This paper reports on an attempt to involve mathematics teachers, with a limited previous experience in exploring statistical concepts, in the collaborative design of computational tools that can be used for simulating data sets. It explores the constructionist conjecture that the design of such tools will encourage designers as learners to reflect upon the statistical concepts incorporated in the tools under development, since generating data-sets on the basis of different characteristics, such as average, spread, or skewness, necessitates the making explicit of thinking related to these notions and the construction of some sense of random processes. It describes how involvement in the design process involved participants in coming to see distributions as statistical entities, with aggregate properties that indicate how their data is centred and spread.

    Abstract:
    The First International Conference on the Teaching of Mathematics was held in Samos, Greece, in July 1998. Presentations by the attendees reflected a recent debate on reforms of the mathematics curriculum and related pedagogy. Chief among these was a greater emphasis on connecting the mathematics curriculum with applications, to make courses in mathematics more "relevant" to students. This manuscript notes that mathematicians tend to teach students to approach data analysis in a constructive manner, proceeding from an understanding of the basic science, while statisticians concentrate on reductive approaches, whereby models are generated upon consideration of the data themselves. It is suggested that departments of mathematics and statistics will need to adopt a new spirit of cooperation, and partner with colleagues in application areas, if curricular enhancements in either domain are to have a reasonable chance at success.

    Abstract:
    We asked active psychological researchers to answer a survey regarding the following data-analytic issues: (a) the effect of reliability on Type I and Type II errors, (b) the interpretation of interaction, (c) contrast analysis, and (d) the role of power and effect size in successful replications. Our 551 participants (a 60% response rate) answered 59% of the questions correctly; 46% accuracy would be expected according to participants' response preferences alone. Accuracy was higher for respondents with higher academic ranks and for questions with "no" as the right answer. It is suggested that although experienced researchers are able to answer difficult but basic data-analytic questions at better than chance levels, there is also a high degree of misunderstanding of some fundamental issues of data analysis.

    Abstract:
    As we consider how we might improve our introductory statistics course we are constrained by a variety of environmental/logistical and pedagogical issues that must be addressed if we want our students to complete the course saying it was useful, it was relevant and practical, and that it increased their communicational, computational, technological and analytical skills. If not properly considered, such issues may result in the course being considered unsatisfying, incomprehensible, and/or unnecessarily obtuse.<br><br>This Webinar will focus on key course content concerns that must be addressed and will engage participants in discussing resolutions. Participants will also have the opportunity to describe and discuss other content barriers to effective statistical pedagogy.

    Abstract:
    While the emphasis in tertiary education in Australia in the past has been on pre-employment training, the rapid expansion in knowledge has meant that there is an increased need to provide graduates with the opportunity to continue their education. This will often be in areas to which they have had minimal exposure in their undergraduate course. Such is the case with Arts graduates, most of whom will have had at best only a basic introduction to statistics and little opportunity to become computer literate. One way of providing this continuing education is through short courses. These are appropriate when the training needs are limited and well defined. Often a more substantial form of training is needed and this has been the motivation for the development of the Post Graduate Diploma in Social Statistics that is described in this paper.
