After entering code in the website, users can click visualize execution to start stepping through their code. One strategy to avoid this confusion is to delay introducing print statements until after students have a solid understanding of return. What is Java Visualizer The Java Visualizer is an in-browser interactive development environment that developers can use to easily step through their Java code.

This project aims to upgrade this tool to modern Java and make it an open source library in the modern sense of the word. Its original version was developed by John Hamer in 2004 and released under GNU GPL (see the original project page ). In the case of Eclipse just click on Windows > Show View > Variables and adjust the console and the view accordingly. LJV is a tool for visualizing Java data structures, using Reflection API and Graphviz. Sometimes you might not be able to open the variables view in debugging mode. Don't forget to input the necessary value in the console when required. Print statements contribute to this misconception because the functionality of a print statement overlaps with their mental model of what return is supposed to do. Step over or step into the code as you like. NEW - a version of Waterloo that use JavaFX throughout is now available for Java 8+. Make sure to distinguish the differences between print statements and return statements to help students understand that these elements are not related.

This allows students to trace through the steps from the beginning of a function call through to return.

Use tools like Python Tutor ( ) and Java Visualizer ( ) to help students build their mental model of function calls. This online course is 6 weeks long, followed by a 2-week period to complete the final exam (online, open book). Get the full Analytics and market share drilldown here. Help students develop a better mental model of the protocol for when a function gets called (for how the function runs from beginning to end). If they are just assuming that Python will return the right thing, this may signify a deep misunderstanding about what Python can do.

It is important to check if students are returning specific things correctly.
