Geogebra

What is Geogebra?

GeoGebra is dynamic geometry software. Constructions can be made with points, vectors, segments, lines, polygons, conic sections, and functions. All of them can be changed dynamically afterwards. Elements can be entered and modified directly on screen, or through the command line. GeoGebra has the ability to use variables for numbers, vectors and points, find derivatives and integrals of functions and has a full complement of commands like Root or Extremum. Teachers can use GeoGebra to make conjectures and prove geometric theorems.

Constructed projects can be exported in several formats. SVG vector images, can be further edited using third party software. EMF vector formats can be directly imported in several Office applications. There are also options for exporting to operation system clipboard and html export.

I reckon this is a good website for Geogebra's Dummies.

Here is the example that I did using Geogebra by following the instruction in that website.

Constructional courseware

By definition from online dictionary, courseware gave me educational software designed especially for use with classroom computers. So constructional courseware means we as a teacher, construct specific educational software in order to be used by the students in the classroom computers.

I found some examples from the websites which shows that some educators have proved the success. One of them is, Lu Xiaoying; He Jian; Qin Tiang; Jiang Dongxu; Chen Wei,Engineering in Medicine and Biology Society, in their summary, “In order to reform the traditional teaching methodology and to improve the teaching effect, we developed new teaching system for course "biomedical materials" in our university by the support of the computer technique and Internet. The new teaching system includes the construction of the multimedia courseware and Web-based e-learning courses. More than 2000 PowerPoint slides have been designed and optimized and flash movies for several capitals are included. On the basis of this multimedia courseware, a Web-based educational environment has been established further, which includes course contents, introduction of the teacher, courseware download, study forum, sitemap of the Web, and relative link. The multimedia courseware has been introduced in the class teaching for "Biomedical Materials" for 6 years and a good teaching effect has been obtained. The Web-based e-learning courses have been constructed for two years and proved that they are helpful for the students by their preparing and reviewing the teaching contents before and after the class teaching”.

From the summary, even though they applied the technique in the University, the idea of constructional courseware is still the same. We still can use this idea and perform to our students in primary or secondary school.

In my point of view, as we are now in 21th Century, a better approach for teaching is no longer chalk and talk but is through constructivism. So the computer will help us to attract the students to become more interested in learning during school day. So as what the example has explained above, we should come out with the same idea. Constructing the courseware that suits with the subjects taught at school. Every teacher no matter what subject they are teaching, they should be aware of this technology and be prepared to implement it.

Lesson Summary

The percentage is essential in life. However, many people do not realize its application in their daily life. We have 30 students. The teacher will prepare the things to sell. We ask them to divide themselves into 6 groups. 3 group of buyers and 3 group of sellers. The sellers will decide the price and the discount percentage of the products. The buyers have to decide which group offers the lowest price with minimal guidance from the teacher. The idea is the student can learn to choose the best price for the same product from different sellers.
We will ask each group of buyers to decide their choice and present their reasons. Then we evaluate and explain if there is a mistake. After that they will switch the position and do the same procedure. They will repeat the same procedure until they have a better understanding about the topic

Student Objectives and Learning Outcomes:


Students
Students collect data from three different sellers so as to:
• Compare data from the three sellers
• Interpret the collected data.
• Make conclusions based on these comparisons


Lesson Outcomes Include:
• Use the Statistics Method (i.e. percentage) to calculate the collected data.
• Use spreadsheet to organize and analyze data and to present their calculation
• Make conclusions supported with critical reasoning.
• Study the issue of marketing.
• Learn to conduct a collaborative study and make comparative analyses.
• Collect important information regarding the different types of offer, analyze the information and reach conclusions
• Evaluate results and present mathematically (percentage calculation)..

Skills developed:

 Students develop the skill of observation.
 Students develop the skill of leadership & organizing.
 Students develop the skill of collecting, analyzing & presenting data.
 Students acquire the skill of developing and presenting an offer.
