    Abstract:
    As Meng (2009) made clear, one of the statistics profession's responsibilities is to be "the first quantitative trainers of future generations of scientists, engineers, policy makers, etc." (not just statisticians). Evidence suggests we have not met this challenge. In fact, our traditional Stat101 courses and texts can poison the statistical well for the people who become our potential sponsors and collaborators. We need to do more than teach 'methods.' We need to show from the first day and throughout the Stat101 experience that our methods exist to help people learn interesting things about issues and topics they are passionate about. This message pertains to the rising generations of professionals and the citizenry at large and it applies to statisticians. Getting the message across may require radically redesigned 'service courses' and a new generation of uber-teachers as Meng (2009) advocated. In the meantime we should use existing materials in ways that show how subject-matter passion can motivate statistical analyses that reveal interesting and important subject-matter insights. As we develop new texts and other materials we need better quality control by authors, editors, and reviewers to assure that our teaching supports our "first quantitative trainer" responsibility.

    Abstract:
    Traditional testing techniques (particularly those used in national or regional examinations) emphasize competitive perspectives of assessment where the main purpose is to differentiate between students for selection or relative ranking purposes (Suggett, 1985). For ranking purposes, information about knowledge possessed by individual students is largely irrelevant. The crucial dimension for both candidate and the examining authority is the position on the rank-order list. Such assessment approaches do not inform either the candidate (whether successful or not) or the teacher (whether past or future) about the level of conceptual development that has been reached or about the possible next steps in the learning process. This report describes some innovative assessment strategies used to explore conceptual development and to describe achievement in terms of the tasks that candidates can do (or not do) rather than in terms of rank order. Such mapping of a set of mathematics results provides more useful information for the parties to the assessment.

    Abstract:
    Previous studies of correlational reasoning have focused on the interpretation of 2 x 2 tables. The research in this article examined age trends in responses to problems involving more than 2 continuous variables. Instruments were developed and administered to Ss from Grade 4 through postgraduate (n = 20 in each grade) to produce multidimensional profiles of student growth. Experiment 1 found that correlational reasoning skills increased with age. Experiments 2 and 3 found that students performance could be improved through instruction. Evidence of convergent and discriminant validity of the instruments was obtained. Although there were similarities between results obtained with 2 x 2 data problems and results on continuous data problems, the evidence in support of a single correlational schema underlying both was ambiguous. There was no transfer, and correlations between the 2 types of performance were weak.

    Abstract:
    Well-defined measures of performance are readily available for baseball players, making the modeling of their salaries a popular statistical exercise. In this article, the salaries for non-pitchers for the 1992 Major League Baseball season are provided, along with numerous measures of the players' previous year's performances. Also included are indicators of each player's ability to switch teams. This dataset is useful in upper-division regression analysis courses because it exhibits many "real world" difficulties that can be remedied using techniques outlined in the course.

    Abstract:
    There are many ways of teaching students to use statistics and all of these methods have their own relative advantages and disadvantages. The use of projects to enhance learning is one of the most effective methods to use. Students during the project duration need appropriate support for the maximum benefit, from the project, to be obtained. Many countries have successfully implemented statistical project work into their education programmes. The experience gained by students and the teachers, involved with the projects, has been of enormous benefit to the statistical education in these countries. Examples of how statistical projects that have been implemented are to be elucidated. Statistics lends itself to the practical aspects of life and enables students to come into contact with real data, often for the first time in their studies. This data can be usefully employed to engage the students in meaningful debate about, for example, the environment and what statistics should be used to emphasise the salient points being made. Project work brings together many facets of education, statistics being one of them.

    Abstract:
    Students often find the fact that a sample statistic is a random variable very hard to grasp. Even more mysterious is why a sample mean should become ever more Normal as the sample size increases. This simulation tool is meant to illustrate the process, thereby giving students some intuitive grasp of the relationship between a parent population and the distribution of a sample mean.

    Abstract:
    We present and discuss three examples of misapplication of the notion of conditional probability. In each example, we present the problem along with a published and/or well-known incorrect - but seemingly plausible - solution. We then give a careful treatment of the correct solution, in large part to show how careful application of basic probability rules can help students to spot and avoid these mistakes. With each example, we also hope to illustrate the importance of having students draw a tree diagram and/or a sample space for probability problems not involving data (i.e., where a contingency table might not be obviously applicable).

    Abstract:
    This paper introduces an outline of the integrated web site produced from our faculties' project offering such services as statistics education, electronic books, and statistical libraries for computer use with a search engine for statistics, which we are currently developing. Statistics is a basic and cross-disciplinary study that should be applied to positive analysis in a wide variety of fields. Both the theoretical side and the practical use as a data analysis tool have to be its primary role. Moreover developing statistical analysis software has been the mainstream of disseminating statistics to the various departments. Computers and its network have become quite popular, still use of data processing software such as spreadsheets is expanding among people in the society. In this circumstance, strong demand for basic statistics education is absolutely increasing. In addition as the Internet is supposed to grow as a large-scale communication media, now and in the future, beyond time and space, to increase information about statistical science and education on the Internet promotes the efficient dissemination of statistics.

    Abstract:
    What people mean by randomness should be taken into account when teaching statistical inference. This experiment explored subjective beliefs about randomness and probability through two successive tasks. Subjects were asked to categorize 16 familiar items: 8 real items from everyday life experiences, and 8 stochastic items involving a repeatable process. Three groups of subjects differing according to their background knowledge of probability theory were compared. An important finding is that the arguments used to judge if an event is random and those to judge if it is not random appear to be of different natures. While the concept of probability has been introduced to formalize randomness, a majority of individuals appeared to consider probability as a primary concept.
