Use Of Applets Research Articles

Learning the Parabola Mediated by Problem-Solving, Semiotic Representations, and Applets in GeoGebra

In this article we evaluate the contribution of the problem-solving approach, semiotic representations and the use of applets designed in GeoGebra when first-semester science and engineering students study the mathematical concept and application of the parabola. At the end of the classroom intervention, a significant improvement was noted in the students' performance, especially in their cognitive thinking activities; that is, in the use of algebraic language, in the appropriation of geometric concepts, and in the problem-solving performance.

Improving the students' learning process through the use of statistical applets

AbstractUndergraduate statistics teaching has always faced the challenge of improving the learning quality on a continuous basis. Interactive statistical applets can enhance statistical knowledge by providing multiple representations of basic concepts and facilitating experimentation. The use of these applets will simplify the efforts for teaching statistics, especially in convincing students of the usability of statistics and facilitating quick learning in undergraduate courses. We developed and implemented a set of web‐based statistical applets from the following areas: Basic Statistics, Coin Toss App, Scatterplot‐Regression Line, Standard Normal Distribution, Normal Distribution, Histogram, Histogram (Case Examples), and Sampling ‐ Canada Map. These interactive applets can perform specific statistical tasks to improve the students' learning process.

Experience of integrating various technological tools into the study and future teaching of mathematics education students

This paper presents our experience of integrating technological tools into our mathematics teaching (in both disciplinary and didactic courses) for student-teachers. In the first cycle of our study, a variety of technological tools were used (e.g., dynamic software, hypertexts, video and applets) in teaching two disciplinary mathematics courses. We found that the tool most preferred by the students was dynamic software, while the applets were almost neglected. In the next cycle, we focused on using various applets in both disciplinary and didactic mathematics courses. We found that if the assignments were applet-oriented, i.e., adjusted to the chosen applet, or vice versa – the applet was chosen appropriately to suit the given assignment – then the students were able to make use of applets in an effective way. Furthermore, the students came to see the potential of applets for improving learning.

Approximation of partial distribution in renewal function calculation

A renewal process with waiting time being the life span of a product is widely used as a statistical model in the analysis of product failures. The renewal function is often the expected number of warranty services for the product. This paper proposes approximation of partial distribution method in renewal function computations. The feasibility of the approach and the use of applets that can draw graphics and do calculations are explored. It is demonstrated in a case study that a partial gamma approximation achieves remarkable accuracy for k-out-of- n product system with exponential component life.
