The Impact of Different Teaching Approaches and Languages On
The Impact of Different Teaching Approaches and Languages on Student Learning of Introductory Programming Concepts A Thesis Submitted to the Faculty of Drexel University by Wanda M. Kunkle in partial fulfillment of the requirements for the degree of Doctor of Philosophy September 2010 Copyright 2010 Wanda M. Kunkle. All Rights Reserved. ii DEDICATIONS I dedicate this dissertation to the memory of Nathan J. Kunkle the loving father who encouraged me to become the person I was meant to be and the highly respected educator who inspired me to follow in his footsteps. Nathan J. Kunkle (1907 – 1965) iii ACKNOWLEDGEMENTS I wish to thank my advisor, Robert Allen, and the members of my dissertation committee for their support and guidance in doing the research and writing required to complete this work. I also wish to thank the Computer Science instructors who helped me recruit the students who participated in my research study, as well as the students themselves. Without the students, there would have been no study. I especially wish to thank the friends and family who encouraged me to keep going when I began to falter because I was feeling overwhelmed by the amount of time and effort I needed to put in to complete this dissertation. Some of those friends are on my dissertation committee, so they are getting thanked twice. Finally, a special thanks goes out to my cousin, Durand Kunkle, who regularly called to ask how I was progressing with my dissertation. He has been planning the celebration for some time now. iv TABLE OF CONTENTS LIST OF FIGURES -

Introduction to Algorithms in Java
Algorithms in Java: Shuffling and Random Numbers Algorithms Introduction Itʹs impossible to study programming – or even talk in depth about it – without talking about algorithms. Theyʹre an essential part of programming. Fortunately, all of us – programmers and non‐programmers alike – have experience with algorithms. Every time you give someone driving directions; every time you use a recipe to cook; every time you follow instructions for using a piece of software – all of these activities (and countless others) involve algorithms. So what is an algorithm? Simply put, an algorithm is a set of instructions, intended to solve a specific problem or accomplish a specific, finite goal, in a direct fashion. What Makes an Effective Algorithm? In general, ambiguity doesnʹt make for a good algorithm; this is particularly true in programming, because computers are mostly incapable of knowing what we want them to do, unless we spell it out precisely. So the algorithms we use should also be precise – even before we translate them into a programming language. An effective algorithm usually has the following characteristics: • Clear conditions of application: What task is the algorithm intended to accomplish, and what are the requirements for us to be able to use it? • Initialization steps & starting conditions: What do we do to prepare our data for the algorithm? How can we tell if weʹre ready to proceed? • Explicit stopping conditions and states: How do we know when weʹre done? How do we know whether we met the desired goal? • Unambiguous steps that lead from the starting conditions to the stopping conditions. Note that “unambiguous” is a subjective term. -

The Components of an IDE (optional) What would we like to see in an IDE? • syntax highlighting & aid in editor • documentation (API) look-up • flexible/configurable build • packaging/deployment options .................................... CS7952 Integrated Development Environments The Components of an IDE (deluxe) What makes us giddy in an IDE? • smart feedback in the editor – learns API of new code – suggestions • coding aids in editor – templates – common refactoring (transformations) • documentation generation • test integration • integration with version ctrl .................................... 2 IDE Examples emacs The *nix swiss army knife of editors, emacs has long functioned as a basic IDE: • syntax-highlighting editor • build support (invokes *nix make) – parses error messages from compilers & other tools • debugger interface • works directly with many version control systems .................................... References, if you are unfamiliar with this: • Compiling in emacs • emacs Debugging mode (CS252) CS7953 Integrated Development Environments emacs Strengths and Weaknesses • highly portable • supports virtually any language you would have a compiler for • even in windowed mode, leans toward keyboard rather than mouse – (not sure if that’s a pro or a con) • outdated interface • high learning curve ................................... -
1 Play with Drjava & and the Scanner Class
CS100M Lab Exercise 8 1 Play with DrJava & and the Scanner class The programming environment that we are going to use is called DrJava. It provides both the abilities to execute a program and to work interactively with the system. In Java, getting input from users requires the use of an object. We’ll talk much more about objects and classes later, but for now you will just get some experience with using an object from the Scanner class to getting keyboard input. 1.1 Compiling and running a program 1. Download from the Lecture Materials page the file Earth.java under the March 13 lecture. Save it to a directory of your choice, e.g., the Desktop. Now start up DrJava and open the file Earth.java. Read the code to make sure you understand it. Have you noticed that you can use a printf method for printing? printf behaves just like fprintf from Matlab. Compile the file (click Compile All) and then run it (select Tools—Run Document’s main Method). 2. Change the print statement to use the println method. (You cannot control the number of decimal places here.) Compile and run the program again. 3. Now change the program to accept user input from the keyboard. Remove the statement that declares variable r and assigns a value to it. You will need an object from the Scanner class to read input. The following statement will create such an object and call it keyboard: Scanner keyboard= new Scanner(System.in); You will learn why the statement looks like this later, but for now simply use the statement.
