Clausi 1 • Session 3 • Title: Coding, For the Love of Mathematics Presenter: Richard Clausi, OCT – Elmira District S.S. (retired 2012) • Currently: Instructor, EU420D, Faculty of Education, Wilfrid Laurier University • : Owner, RC Software and Data (registered 1981) • Slides will be available at: http://www.kw.igs.net/~raclausi/coding.pdf Session Description: Coding, a new player in the elementary school curriculum, offers teachers and students a new way to explore mathematics. 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.

Clausi 3 A code…. “In a code, a word or phrase is replaced with a word, number or symbol. For example, secret agents have codenames, words that are used instead of their real names in order to mask their identities. Similarly, the phrase ‘Attack at Dawn’ could be replaced by the codeword ‘Jupiter’ and this word would be sent to the commander in the field” from: The Code Book by Simon Singh, page xvi ISBN 0‐385‐49532‐3 17/10/2017 Slides (c) 2017 Richard A.

Look at this: • You're looking at the Pong inspired game that Justin Trudeau created at Code.org's "Hour of Code" event back in December. Built using a beginner‐friendly block based approach, this technique is commonly used to teach new programmers (youth and university students alike) how to write code. • It may look simple, but the reality is that, by 2021, the Information and Communications Technology Council forecasts that over 200,000 digital jobs could go unfilled by Canadian talent –and that's something we need to fix, because the global economy is becoming increasingly digital. • From buying groceries, and managing our kid's sports teams, to the computer programs and technology used in workplaces across Canada, more and more aspects of our lives are touched by technology on a daily basis. • It is important that Canadians of all walks of life have the skills needed to navigate this new economy, so they are prepared for the jobs of today, and tomorrow. 17/10/2017 Slides (c) 2017 Richard A.

  • Introduction to Programming in Lisp
    Introduction to Programming in Lisp Supplementary handout for 4th Year AI lectures · D W Murray · Hilary 1991 1 Background There are two widely used languages for AI, viz. Lisp and Prolog. The latter is the language for Logic Programming, but much of the remainder of the work is programmed in Lisp. Lisp is the general language for AI because it allows us to manipulate symbols and ideas in a commonsense manner. Lisp is an acronym for List Processing, a reference to the basic syntax of the language and aim of the language. The earliest list processing language was in fact IPL developed in the mid 1950’s by Simon, Newell and Shaw. Lisp itself was conceived by John McCarthy and students in the late 1950’s for use in the newly-named field of artificial intelligence. It caught on quickly in MIT’s AI Project, was implemented on the IBM 704 and by 1962 to spread through other AI groups. AI is still the largest application area for the language, but the removal of many of the flaws of early versions of the language have resulted in its gaining somewhat wider acceptance. One snag with Lisp is that although it started out as a very pure language based on mathematic logic, practical pressures mean that it has grown. There were many dialects which threaten the unity of the language, but recently there was a concerted effort to develop a more standard Lisp, viz. Common Lisp. Other Lisps you may hear of are FranzLisp, MacLisp, InterLisp, Cambridge Lisp, Le Lisp, ... Some good things about Lisp are: • Lisp is an early example of an interpreted language (though it can be compiled).

  • Polish Python: a Short Report from a Short Experiment Jakub Swacha Department of IT in Management, University of Szczecin, Poland [email protected]
    Polish Python: A Short Report from a Short Experiment Jakub Swacha Department of IT in Management, University of Szczecin, Poland [email protected] Abstract Using a programming language based on English can pose an obstacle for learning programming, especially at its early stage, for students who do not understand English. In this paper, however, we report on an experiment in which higher-education students who have some knowledge of both Python and English were asked to solve programming exercises in a Polish-language-based version of Python. The results of the survey performed after the experiment indicate that even among the students who both know English and learned the original Python language, there is a group of students who appreciate the advantages of the translated version. 2012 ACM Subject Classification Social and professional topics → Computing education; Software and its engineering → General programming languages Keywords and phrases programming language education, programming language localization, pro- gramming language translation, programming language vocabulary Digital Object Identifier 10.4230/OASIcs.ICPEC.2020.25 1 Introduction As a result of the overwhelming contribution of English-speaking researchers to the conception and development of computer science, almost every popular programming language used nowadays has a vocabulary based on this language [15]. This can be seen as an obstacle for learning programming, especially at its early stage, for students whose native language is not English [11]. In their case, the difficulty of understanding programs is augmented by the fact that keywords and standard library function names mean nothing to them. Even in the case of students who speak English as learned language, they are additionally burdened with translating the words to the language in which they think.

  • 4 MICRO WORLDS: TRANSFORMING EDUCA TION 1 Seymour Papert
    MICRO WORLDS: 4 TRANSFORMING EDUCA TION 1 Seymour Papert Arts and Media Technology Center Massachusetts Institute of Technology Cambridge. MA Looking at how computers are used in education, one is tempted to start classifying. It's a little dangerous to do this, but I would like to start off with a very crude classification of three ways of using computers, just to place a certain set of problems into perspective. First, as tutorials in one sense or another - which is by far the most widespread, best known, and earliest use - where the computer serves as a sort of mechanized instructor. Secondly, as tools for doing something else: as calculators, word processors, simulators, or whatever. And thirdly, a different concept altogether: as microworlds. Here I shall concentrate on the notion of microworld and talk about its relations both to computers and to theories of learning. The other uses of computers surely have a role - but they are not what will revolutionize education. One microworld which is already widely known is the Logo turtle mi­ croworld. Briefly, this world is inhabited by a small object on the screen. In some versions, it is shaped like a triangle, in others, like an actual turtle. To make it move and draw lines, you talk to it by typing commands on the keyboard. For example, if you say FORWARD 50, the turtle will move in the direction it's facing and draw a line 50 units long, 50 "turtle steps" children might say. Then if you say RIGHT 90, it will turn 90 degrees. And then you can tell it to go forward again, or back, turn through any angle, or lift its pen up so it moves without leaving a trace.

  • Changing Logo from a Single Student System to a 3D On-Line Student Collaboratory/Participatory Shared Learning Experience
    Changing Logo from a Single Student System to a 3D On-line Student Collaboratory/Participatory Shared Learning Experience Dr. James G Jones University of North Texas [email protected] Theresa Overall University of North Texas [email protected] The concept of Logo to support constructive learning has been in existence since the 1960’s. Logo as implemented in computer software in the 1970’s has focused on either single student to single computer or a group of students sharing a single computer. Later versions of Logo have supported multi-user networking, but have not truly provided a shared learning environment where students using single systems at distant locations can work together and view each other’s work. This paper will discuss the potential of combining Logo concepts with on-line 3D environments to create engaged participatory learning environments/experiences for students. This approach could expand Logo so that it can allow classrooms connected by the Internet to simultaneously engage in K-12 projects about mathematics, language, music, robotics, telecommunications, and/or science. This paper and the presentation at the TCEA conference will demonstrate what an on-line 3D participatory system looks like and show the initial software modules developed for classroom use. Logo One of the primary purposes of the Logo programming environment is to support constructivist learning, such that students create knowledge through interaction with other people and the world around them. The Logo Programming Language, a dialect of Lisp, was created in the 1970’s to promote the concept of Logo as a learning tool (What is Logo, 2003).

  • Drawing with Recursion
    Leone Learning Systems, Inc. Phone 847 951 0127 Leone Learning Systems, Inc. 237 Custer Ave Fax 847 733 8812 Evanston, IL 60202 Wonder. Create. Grow. Email [email protected] Drawing with Recursion TJ Leone April 2005 . Introduction In the unit on Combining Functions, you learned that you can invoke a procedure you wrote from inside another procedure. In the example below, the procedure triangle.inches invokes the procedure feet.to.inches: to feet.to.inches :feet op product 12 :feet end to triangle.inches :side fd feet.to.inches :side rt 120 fd feet.to.inches :side rt 120 fd feet.to.inches :side rt 120 end One of the things that make Logo so powerful is that Logo procedures can also invoke themselves. Here’s an example (if you try it, you’ll need to use the Halt button to stop it): to circle fd 1 rt 1 circle end This technique of writing a procedure that invokes itself is called recursion. Recursion can be used to draw simple figures like circles or polygons. It can also be used to draw complex shapes called fractals. Fractals can be mathematical structures like the Sierpinski triangle, Koch snowflake, Peano curve, Mandelbrot set and Lorenz attractor. Recursive drawings can also describe many real-world objects that do not have simple geometric shapes, such as clouds, mountains, turbulence, and coastlines. In this unit, we will start with simple designs to explore the basics of recursion, and then move on to some fractals.
