Mare de Déu de Lorda, 08034 Barcelona Spain eSeeCode.com e-mail: [email protected], [email protected] Abstract. It has been almost 50 years since the creation of Logo – one of the first educational programming languages. Although most people agreed that it was important to teach computa- tional thinking to children, only recently have school and district leaders begun to adopt curricula to include it – mainly through Scratch. In many cases this adoption has failed to provide the right methodologies and tools to teachers. In this paper, we analyse some of the different languages used in classrooms today and we propose an improved alternative that we have created – eSeeCode. We also share our experiences using this language in classrooms and how students can learn using this tool. Keywords: informatics curriculum, promoting informatics, programming language. 1. Overview Reading Papert’s Mindstorms: Children, Computers, and great ideas, one can have the feeling that we have not advanced much in the past 35 years (Papert, 1980). Many coun- tries are trying to include Coding as a required skill to learn in schools, either as a spe- cific subject or as part of a technology course. However, in many schools, teachers do not have the resources, materials and/or knowledge to bring computer science and cod- ing into the classroom.

  • Musical Abstractions and Programming Paradigms
    Musical abstractions and programming paradigms Erich Neuwirth, [email protected] Didactic Center for Computer Science, Faculty of Computer Science, University of Vienna Abstract Many educational programming environments (e.g. Imagine) have facilities to enrich programs with music. In most cases, this programming constructs allow to play simple melodies. It is not easily possible to play more complex music either containing chords or polyphonic structures. On the other hand, some tools (like MSWLogo and FMSLogo) implement low level MIDI commands. These commands allow talking to the sound producing device directly, but the code needed to produce music this way conceptually is very remote from the usual representation of music. Therefore, we will study some conceptual abstractions for implementing music with two different tools. These tools are a toolkit for making music with LOGO and a toolkit for making music with Microsoft Excel; both toolkits are available for download. Since the programming concepts are quite different in spreadsheet tools like Excel and functional programming languages like LOGO, it is interesting to see how core ideas of music representation can be implemented in different programming philosophies. To illustrate this, we can describe the topic of this paper as a discussion of the question how one should connect the following standard representation of a musical phrase: 4 4 with these two representations Excel 0 note 1 60 500 [[ 0 [ note 1 60 500 ]] 500 note 1 62 500 [ 500 [ note 1 62 500 ]] 500 note 1 64 500 [ 500 [ note 1 64 500 ]] 500 note 1 67 500 [ 500 [ note 1 67 500 ]] 500 note 1 72 250 or [ 500 [ note 1 72 250 ]] 250 note 1 67 250 [ 250 [ note 1 67 250 ]] 250 note 1 64 250 [ 250 [ note 1 64 250 ]] 250 note 1 62 250 [ 250 [ note 1 62 250 ]] 250 note 1 60 1000 [ 250 [ note 1 60 1000 ]]] and how these representations can be used to understand musical structure and how much knowledge of musical structure is necessary to convert between these representations.

In some procedures, words and lists, so it does not differ too much from of Achievements in Materials cases, an operator can use an application that will export each other high-level languages. The main advantage is the simplicity and Manufacturing Engineering 2011 point of the trajectory to the CAD program and will present the of the program, while the disadvantages include the fact, that in path in an intelligible form [3,5]. However this method fails if the most cases Logo language is available as interpreter. This means path is created in a dynamic way, based on the result of that during each procedure call, the program code is every time conditional statements in the program. In this case, you can try to re-translated line by line. This affects the speed of program examine all the alternative trajectories, but this would require execution. For this reason, some dialects of the Logo offer sophisticated tool for source code analysis and developing the compilation to the intermediate code ("p-code") or a standalone The robot programming language form of path presentation in the CAD application. Another way of compiler. solving this problem may be the translation of the robot program There are also implementations of the Logo language in to a description similar to the pseudo code, which could be which commands have been translated into the user national interpreter written in the Logo language interpreted in a certain graphical environment. In this case, it was language.

This session is a light overview of entry‐level programming (code.org, scratch and LOGO) as a way to engage and nurture mathematical thinking. This new tool for problem solving allows us to use simple programming to understand and apply “tough” concepts such as recursion, modularity and multi‐tasking to ARDUINO programming and Mouse Mazes, calculating TT, Newton’s Method for Square Roots, Fractals and Mandelbrot Set. • I hope that you will leave with inspiration and ideas that you can use to explore your own personal mathematical adventures. • ** This slide will be the last slide in my presentation so you can copy down the web address, later, if you wish. 17/10/2017 Slides (c) 2017 Richard A.
