2. Summary  Motivation  What it is?  Strategy  Visual Language  Tangible interface  Field tests  Published work  Questions
3. Motivation  Traditionally programming is learned/taught with industrial tools.  Borland C++  Visual Studio  Eclipse  Others…  Textual representation is a problem for beginners  Removing the language complexity from the learning process. ◦ If, se, si, wenn, если, ? ◦ Eyes don’t have language.  Understanding the results – Tangible interface  Student needs to know how to read the results in order to grade them.  Botbeans shows the results. ◦ Robot interacting with the real world.  Starting point to object-oriented languages  Basic control structures.
4. What it is?  Environment to teach and learn computer programming.  Graphical representations for basic control structures.  Graphical display of memory.  Hybrid display for logic representation.  Tangible interface  Collaboration catalyzer  Motivation
5. Strategy 1. Complexity  Solution: ◦ Visual language  Better understanding of the algorithm. 1. Lack of motivation  Solution: ◦ Tangible interface  Keep the student emerged and motivated.  Seed collaboration between students. 2. Initial fear  Solution: ◦ Rich Client Platform  IDE without any interface cluttering.  Avoid information overload.
7. Diagrammatic/node based  Positive  Obvious logic flow  Function representation  Negative  Textual data-types  Textual logic and mathematical expressions
8. Block based  Positive  Data types validation  Block enclosing  Negative  Logic flow not so obvious  Complexity grows quickly with the problem.
9. Hybrid solution  Block-based  "In graphical block programming, users manipulate and connect puzzle-piece objects to build their programs.“  "allowing only complementary blocks to connect prevents users from making syntax errors“ ◦ R.V. Roque, “OpenBlocks : an extendable framework for graphical block programming systems.”  Node-based  "learning a programming language is easier if people who are visual learners by nature began by learning a data flow programming language“  "The concepts of CGs are easily matched to those found in textual programming languages“ ◦ B. Smith, “Conceptual graphs as a visual programming language for teaching programming,” Visual Languages and Human- Centric Computing, 2009. VL/HCC 2009. IEEE Symposium on, 2009, pp. 258-259.
10. Graphical Interface
11. Expression builder  On top off MIT OpenBlocks  Heavy customized. ◦ Dynamic Blocks language definition. ◦ Off-screen rendering.  Used in Scratch and Google App Inventor
14. Tangible interface  How to output in Botbeans?  Robot’s actions ◦ Robot movement. ◦ Robot small display. ◦ Robot speaker.  Input?  Sensors connected to robot.  Understanding the results  Did the robot crash?  Did it turned left instead of right?  …  Multiple points of interaction with the learning tool  Screen for visual programming  Robot for input, output and debug.
15. Tangible interface  "the use of the tangible interface results in a more child- focused activity. In other words, children seem to be more actively involved and self-motivated“  "tangible interface is more inviting and provides better support for active collaboration“  "if for no other reason than the tangible interface consists of multiple input devices that can be manipulated independently, while the graphical condition consists of only a single input device."  M.S. Horn, E.T. Solovey, R.J. Crouser, e R.J.K. Jacob, “Comparing the use of tangible and graphical programming languages for informal science education,” Proceedings of the 27th international conference on Human factors in computing systems, New York, NY, USA: ACM, 2009, pp. 975–984.
