Identifying and Nurturing Mathematically Gifted Students

The Bsc (Hons) Mathematics with pathway in Statistics course cordially invites you to a seminar titled:

"Identifying and Nurturing Mathematically Gifted Students"
with a guest talk from Dr Demetra Pitta-Pantazi (University of Cypruson Wednesday 11th  March 201516:00-17:00 in Room CY114.

Abstract
The aim of this presentation is to show a new tool for the identification of mathematically gifted students. This identification tool is a result of a three year research project which aimed at the identification and nurturing of mathematically gifted students. During the presentation the theoretical background, the tool itself and the procedure followed for the identification of mathematically gifted students will be presented. The results yielded by the implementation of the identification tool to 360 elementary school students will also be discussed. Finally, a broad overview of some of the material developed for nurturing mathematically gifted students will be presented. 



Biography
Dr. Pitta is an Associated Professor in the Department of Education at the University of Cyprus. Her undergraduate studies include a Bachelor's Degree in Primary School Teaching (Pedagogical Academy of Cyprus and University of Athens, 1993) and a Master and Ph.D. in Mathematical Education (University of Warwick, M.Sc. 1994 and Ph.D. 1998). She has taught at the University of Warwick (1995-1997) and at the Pedagogical Institute of Cyprus (1999-2001).

Her research interests include: Understanding the structure of mathematical thinking, cognitive development of mathematical concepts, use of new technologies in teaching and learning of mathematics, mathematical creativity, recognition and gifted students in mathematics education, cognitive style and math skills, educational training for teaching mathematics.

Meta-analysis: essential tool for evidence-based clinical and public health practice

The Bsc (Hons) Mathematics with pathway in Statistics course cordially invites you to a seminar titled:

Meta-analysis: essential tool for evidence-based clinical and public health practice”

with a guest talk from Dr Nicos Middleton (Cyprus University of Technology).

Abstract

In clinical and public health research, it is not uncommon to identify studies with uncertain, or even conflicting, findings with regards to the effectiveness of certain therapeutic or preventive treatments. While individual trials might be underpowered and fail to show benefit (e.g. a statistically significant difference between the experimental and control/placebo groups), when results from individual studies are combined using appropriate techniques, significant benefits of treatment may be shown. An often cited historical example is the evidence on the effectiveness of streptokinase in improving survival after myocardial infarction. A retrospective review of the published evidence suggests that there was clear evidence of its benefits (had a meta-analysis been conducted) as early as 1973 after only 8 small studies involving 2432 patients. Yet it took several years, another 25 studies and 35000 randomised patients before its wide adoption in clinical practice. Therefore, there was a period at which patients were essentially deprived of an effective therapy, and thus challenging the critical premise of healthcare practice “first, do no harm”. Meta-analysis is a simple but powerful statistical technique which systematically collates and synthesizes findings across independent trial/studies considered combinable (i.e. feasible and justifiable), with the aim to provide a summary and more precise quantitative estimate, giving due weight to the size of the different studies. It is most often used in assessing the effectiveness of healthcare interventions, but not restricted to this case since it can also be used for diagnostic, prognostic or aetiological research questions. Meta-analyses are nowadays considered an integral tool of evidence-based (clinical and public health) practice while the validity of a meta-analysis depends on the methodological quality of the systematic review on which it is based. Other than providing increased statistical power to detect small but potentially clinically significant effect, meta-analyses provide the opportunity to explore the robustness of the findings using sensitivity analyses, to quantify and investigate possible sources of heterogeneity in the observed estimates, to identify patient- or study-specific factors that may relate to the observed heterogeneity and effect size (sub-group analysis and meta-regression) as well as to assess the likely presence of publication bias (i.e. the underrepresentation of negative findings in the literature).

Indirect Questioning Techniques in Sample Surveys

The Bsc (Hons) Mathematics with pathway in Statistics course cordially invites you to a seminar titled:

“Indirect Questioning Techniques in Sample Surveys


with a guest talk from Professor Tasos C. Christofides (University of Cyprus).


Abstract

Survey practitioners often experience difficulties in collecting reliable data due to various sources of non-sampling error and in particular non-response. In case the issues under investigation are of sensitive nature, such as sexual orientation, tax evasion, or involvement in criminal activities, people are reluctant to participate, and even if they agree to participate, false or misleading answers are given by many of them. Indirect questioning techniques offer a solution to this problem. These are techniques designed in such a way that the information provided by a participant is not incriminating and thus his/her privacy is protected. However, based on the information collected from all participants, the investigator is able to estimate parameters of interest related to the stigmatizing characteristic. In this talk, we present in an elementary way indirect questioning techniques, such as the randomized response model and the item count technique.
