We start from the assumption that school mathematics knowledge could be better explained if social practices were considered to be generators of knowledge. This perspective changes the way we look at what school mathematics knowledge is and what it takes to teach and learn it. In this article, we will present a teaching situation about periodic…

This paper analyses technology-based instruction on data-analysis with box plots. Examples of instruction taken from the research literature inform a study of two classes of 17 year-old students (upper secondary) in which the mathematical relationships that their teachers targeted are distinguished as being, or not being, relevant to statistical…

This case study investigated the impact of a spreadsheet (EXCEL) exploration on the understanding of statistical graphs among twenty Singapore secondary school students of average ability. Four EXCEL templates were constructed to allow students to explore four aspects of statistical graphs: zero in scale, effect of different scales, size…

The 10th International Conference on Educational Data Mining (EDM 2017) is held under the auspices of the International Educational Data Mining Society at the Optics Velley Kingdom Plaza Hotel, Wuhan, Hubei Province, in China. This years conference features two invited talks by: Dr. Jie Tang, Associate Professor with the Department of Computer…

This book is designed to be a quick and easy resource for anyone teaching physics for the first time. Written after extensive research, this book is filled with reliable labs, demos and activities that work well in the classroom. Also included are lesson plans, diagrams, and teacher notes for every activity. The book is not the end--it is just a…

This book presents a description of the major curriculum philosophies that have influenced educators and schooling over the last century. The author analyzes four educational visions (Scholar Academic, Social Efficiency, Learner Centered, and Social Reconstruction) to enable readers to reflect on their own educational beliefs and allow them to…

The purpose of this study was to examine the effects of an intervention involving reciprocal peer tutoring and self-graphing of reading data on the disruptive behavior, active responding, and reading fluency of students with emotional or behavioral disorders (EBD). Four middle school students with EBD participated in this research. Results…

The integration of history into educational practice can lead to the development of activities through the use of genetic "moments" in the history of mathematics. In the present paper, we utilize Oresme's genetic ideas--developed during the fourteenth century, including ideas on the velocity-time graphical representation as well as geometric…

Teachers of physiology at all postsecondary levels were asked to participate in a survey about the possible sources of students' difficulty in learning physiology. Sixty-three physiology teachers responded to the 18-question survey; 35 of the respondents also responded to a request for written comments about this issue prior to taking the survey.…

Introductory college level geography textbooks can be enhanced by using scatter diagrams and double criteria classifications, both of which reveal generalizations and specific facts about location. Scatter diagrams, a series of dots on a graph, illustrate relationships among phenomena that covary, e.g., national birth and infant mortality rates.…

How often do our students long for black and white rather than the shades of grey that history generally presents us with? Understanding the Arab-Israeli conflict is all about understanding diversity and complexity in all their shades of grey. Alison Stephen, teaching in an immensely diverse school herself, is determined not to over-simplify the…

The use of computer graphics in an introductory statistics course is described. The advantages over more traditional diagrammatic representations are discussed and an outline is given of two computer-supported graphic display systems. A description is also provided of an experiment, designed to evaluate the influence of such graphic aids. (JP)

One way in which a computer simulation can convince students of the validity of formulas for the density and distributive functions of the sum of two variables is described. Four computer program listings are included. (MNS)

The graphing of intricate curves and the fundamental theorem of algebra lead to a third discovery with microcomputers: Lagrange polynomials. Teaching suggestions for helping students to explore continuous change, interpolation, roots, and shifting and symmetry are presented, with a computer program listing. (MNS)

Examples for determining the equation of a line through two points or a quadratic function that contains three noncollinear points are presented. (MNS)
