LINEAR AND QUADRATIC GRAPHS WITH THE AID OF TECHNOLOGY

Author: Gary Asp, John Dowsey & Kaye Stacey

Publication Year: 1993

Abstract

This paper describes the trial of a unit of work on linear and quadratic graphing with six year
10 classes. Two treatments were developed. The computer treatment made use of the
ANUGraph software package, while the calculator treatment paralleled the computer treatment
but used a combination of previously prepared graphs and graphs constructed by the student
with the aid of a calculator. The emphasis in both treatments was on the interpretation of
graphs related to real situations. Comparisons between pre-test and post-test results and
interviews with twelve students showed that students learnt to handle the software proficiently,
and that both groups improved on most of the topics taught. However, the calculator group
seemed to be advantaged by practising plotting of points by hand. Implications/or future
work are discussed.

Short Communications & Round Tables

The following documents are essential to read and complete when considering submitting a short communication or round table to the MERGA conference (available in the Submission section of this website).

MERGA Paper Template – to be used to write the abstracts which are then submitted to the MERGA conference website
MERGA Publication Agreement – to be submitted on the MERGA conference website at the time of the abstract submission

Submissions not exceeding one page are required for short communications and round tables. The submissions must be prepared using the conference template, and can include essential references. They will be reviewed by the Editorial Team and, if accepted, will be published in the conference proceedings as one-page abstracts (not as papers). Presenters are invited to prepare a paper for distribution at the conference, but these papers will not be included in the proceedings.

Short communications are suitable for reports on research in mathematics education that do not fully meet the requirements for published papers. These might include works in preliminary stages, reports of pilot projects, initial reviews of literature, ideas or suggestions for future study, and briefer discussions of particular issues. Short communications allow new researchers to obtain feedback on projects in a constructive and supportive environment, and foster the building of links between researchers with similar interests.

Short communications are presented by author(s) only, allocated half of the time for research reports (in past, this was 20 minutes). At least 5 minutes is to be allocated for audience questions and open discussion.

Round tables are suitable for presenters seeking involved interaction with the audience in relation to their research or topic of interest in mathematics education, and for those sharing their insights and advice with the early career colleagues. These might include discussion of an emerging topic, co-analysis of provided student work, solving a mathematical task, or discussing the demands and benefits of reviewing for high quality journals. Round tables allow finding peers with similar research interests, exploration of new research avenues, and building the capacity of MERGA community.

Round tables are led by author(s) only, allocated the same time as research reports (in past, this was 40 minutes). The abstracts should make clear the interactive element of the proposed activity, with no more than 15 min of the session time in a presentation mode.

Research Papers

The following documents are essential to read and complete when considering submitting a research paper to the MERGA conference (available in the Submission section of this website).

Research papers can take two major forms:

1. Reports of empirical investigations

When empirical investigations are reported (such as in an experimental intervention, confirmatory study, or action research, etc.), the paper should also include

a statement of rationale for methodologies used in collecting and analysing data;
a critical discussion of data findings in the light of the research literature; and
in the literature review, prior work in the area should be acknowledged and an explanation of how the work reported in the paper builds on that earlier work should be included.

2. Reports that are not based on empirical research including:

a theoretical discussion;
a position paper;
a report of scholarly enquiry in progress;
a literature review, a meta-study;
an account of a new initiative;
a reflective critique of practice; or
any mixture of these or other recognised scholarly forms.

When the work is a theoretical discussion, a position paper, a report of scholarly inquiry in progress, a review of literature, a theoretical study, a meta-study, an account of a new initiative, a reflective critique of practice or any mixture of these or other recognised scholarly forms, the material presented must be discussed critically, and alternative points of view relating to themes presented should be appropriately argued.
It is expected that presenting authors will have 40 minutes to present their work at the conference. At least 10 minutes must be allowed to field questions and comments from the audience.

Structure of research papers – All papers for publication in the conference proceedings should contain the following:

a statement of the problem/issue and a discussion of its significance;
a critical analysis of the research literature as it relates to the topic of the paper; and
conclusions and implications for mathematics education derived from the study.

All papers must respect MERGA’s ethical guidelines relating to research work. Papers should not be more than the set length. In addition, papers must be: readable; free of grammatical, spelling and typographical errors; and adhere strictly to style requirements advertised by the conference proceedings Editorial Team.

Originality – Only research papers that are substantially different from work that has been published previously will be considered for publication in the conference proceedings and/or presentation at the conference.

Reviewing of research papers – Research papers will be blind reviewed by a panel of peers approved by the conference committee. The main purpose of the refereeing process is to contribute to the growth and development of quality practice in mathematics education research. Thus reviewers are asked to assist authors by providing helpful feedback and to comment on the suitability of papers for presentation at the conference. Accordingly, it will not be assumed that published papers presented at the conference will be as polished as articles in scholarly journals. Referees will be asked to assess papers being reviewed against the accepted norms for scholarly works presented at MERGA conferences, as set out above.

Each conference proceedings’ Editorial Team will exercise discretion over the reviewing process. Reviewers’ comments will be returned to the authors. Authors whose papers are not accepted for publication may be invited by the editorial panel to present their paper at the conference as a Short Communication, with a 1-page abstract (which they will be invited to provide) being published in the proceedings. Papers may be rejected outright, with no opportunity for presentation at the conference in an alternative form.

Research Symposia

The following documents are essential to read and complete when considering submitting a research symposium to the MERGA conference (available in the Submission section of this website).

Presentation of groups of published papers related by theme in the form of a research symposium is encouraged. The symposium forum will be particularly suitable for presentations relating to a single large project or presentations that explore topical themes from different and/or related perspectives. Special Interest Groups [SIGs] are encouraged to consider the symposium option as a means for sharing and discussing current research.

A symposium should consist of no more than four presentations of about 15 minutes duration each. The written papers should be half the length of research papers as described for research papers. Both research report types – empirical or non-empirical – are acceptable as published symposium papers.

A brief overview of the symposium (limit one page), including a symposium title, an introduction to the theme/project, and a short introduction to each of the 3-4 contributions, must be submitted with the set of short papers. Please list the symposium convenors as the authors on the first page, and name the paper authors in the text description.

The symposium proposer will also nominate a person to chair the symposium, and a discussant can also be named if desired. This information should accompany the collection of papers submitted for review.

The set of symposium papers (and the overview) will be blind reviewed by a review panel. The main purpose of the reviews is the same as for published papers, and the same criteria are used. The reviewers will be asked to consider the cohesiveness of the set of symposium papers. They will indicate whether the symposium as a whole, and each paper within it, should be “accepted”, “rejected” or if it “requires revision”. If it is deemed that one, some or all of the papers are in need of revision, the reviewers will outline which papers need to be revised and provide suggestions for the required changes. When the revisions are made, the symposium papers will be re-submitted and the set of papers will be sent to the same review panel for further consideration. As with research papers, the final decision about which symposium papers will be published is at the discretion of the Editorial Team.

The date for submission of the collection of symposium papers is the same as for Early Bird papers. This date has been set for the benefit of the group of authors of symposia papers. Should the symposium papers require revision, the authors will have the time to make the corrections and resubmit the set of symposium papers to be re-reviewed by the original reviewers.

Presentation of symposia: Symposia are presented by author(s) only, usually within a 90 min block. At least 10 minutes must be allocated for audience questions and open discussion.
