Abstract: We discuss how to build 3D models of real-life objects. We can design models on a computer desktop, laptop, tab, or on smartphone. Once the model is designed, we can verify the accuracy using the Augmented Reality app. We will also see how can we access the existing 3D models available on GeoGebra site.

Abstract: Growing culture of internet and technology use has changed the landscape of educational practices. Technology use is even impressive in mathematics education to visualize, materialize and build mathematical concepts. In this context, my presentation in the conference will explain an experimental case, showing that students were highly involved in learning process with GeoGebra based interactive learning resources. Interacting with the resources, learner has developed better understanding and sense of visualization of their learning content. Additionally, the presentation will focus to give a demo of GeoGebra integrated learning resources that has created more engaged and better interactive learning opportunities for students to develop their higher order mathematical thinking.

Abstract: Sometimes the ways students can interact with your worksheets using the basic features provided by GeoGebra are not powerful enough or too difficult to be used by your students, especially younger ones. Using scripting you can create simple-to-use constructions with more sophisticated interactivity.

Common uses of scripting are:

1. checking students' answers by letting them enter their answers into text fields and using scripts to check if they are correct,

2. creating objects using user inputs with click of button,

and many more.

A script is a sequence of commands, that are executed one after each other. GeoGebra supports two scripting languages - GGBScript and JavaScript. In this talk I will demonstrate how these can be used in making the GeoGebra applet more interactive.

Abstract: Open source Dynamic Geometry Software such as GeoGebra has the potential to transform the mathematics classroom into a dynamic interactive learning environment where the learner can engage with the subject through explorations, reasoning and meaningful problem solving. Such tools can go a long way in facilitating the inquiry-based approach to learning mathematics.

This talk will focus on the role of GeoGebra in enabling students to explore mathematical concepts though multiple representations (pictorial, graphic, numeric and symbolic), interpret spatial relationships among geometrical objects and make conjectures leading to argumentation and proof. The potential of the dragging feature to encourage exploration and proof will be analysed through the theory of variation. Some examples of students’ investigations will be used to highlight the development in their mathematical thinking as they engaged with some open-ended tasks.

Abstract: In this talk the latest developments of GeoGebra will be presented. These include, for example, new features in GeoGebra Classroom and GeoGebra Notes. GeoGebra Classroom is a virtual platform for teachers to give interactive and collaborative lessons. You can easily distribute interactive GeoGebra activities and books to your students and see their progress in real-time while they are working. The results can then be discussed with the whole class or you can give individual feedback and support. GeoGebra Notes allows writing with a digital pen next to interactive GeoGebra graphs. You can also include videos, pdfs and websites on your slides which can be shared with other teachers and your students. The new GeoGebra Suite app will also be presented in this talk. In addition, an outlook on future developments is given.

Abstract: Year 2020 brought in challenges which educators and developers of various EdTech products all around the world turned into an opportunity to grow and innovate. Considering the need for teachers to observe and interact with the work of students as they worked in the remote learning, GeoGebra brought in GeoGebra Classroom. This feature of GeoGebra has enabled educators to assign activities to the entire class and monitor the work done by the students in real time. With GeoGebra Classroom educators got the power to not only engage students but also pause the activity to discuss the concepts being explored, give feedback and do hand holding for some or all the students. An effective tool for synchronous and asynchronous teaching, GeoGebra classroom has indeed made the lessons interactive. In this presentation all features and possibilities with Google Classroom will be demonstrated and highlighted.

Abstract: The programming of GeoGebra can have effect at different levels. It is possible to link most objects in GeoGebra with each other in various ways and thereby visualize procedures, concepts, relations and situations in mathematics and physics. We can also program GeoGebra in Java Script or in GeoGebra Script. These possibilities give us many different opportunities to explore and visualize relations and situations in mathematics and physics. I will give some examples of the programming I have done in GeoGebra in mathematics and physics regarding these different levels.
