VisualLogic: Generate codes from flowchart

-----

Overview

Visual Logic provides a minimal-syntax introduction to essential programming concepts including variables, input, assignment, output, conditions, loops, procedures, arrays and files.  Based on research that shows students have more success when they start by focusing on concepts rather than syntax, Visual Logic allows instructors to present material in a clear and illustrated manner. Programming fundamentals are covered in an appropriate problem-solving context, empowering rather than overwhelming the student.

The Visual Logic approach is consistent with National Curriculum Models:

• IS'97 (revised as IS 2001) provides model curriculum and guidelines for undergraduate degree programs in Information Systems. IS'97 topics for the programming course (IS'97.5) includes "algorithm development; objects and event driven representations; data flow notation; programming control structures; program correctness, verification, and validation." It is interesting to note that no specific language syntax is mentioned. This is consistent with our focus that skills, not syntax, should be the focus of an introductory programming course.
• Computing Curricula 2001 (www.acm.org/sigcse/cc2001/). The CC2001 report includes a call for course designs of various types, including a minimal-syntax approach, described below:
  • "By introducing students to basic algorithmic concepts and constructs apart from any particular executable language, this approach minimizes the preoccupation with syntactic detail that demands for successful program execution typically engender among students. Instead, it requires that students reason about and explain the algorithms they construct...
  • "Once students have a solid grasp of the algorithmic foundations and the range of data and control structures [...], they can then move on to a more conventional language, either partway through the first course or, at the latest, the beginning of the second course. Because students have experienced a wider range of both data and control structures early, their later progress through conventional programming work can occur more rapidly and class time can be more explicitly focused on issues of effective programming practices and systematic debugging skills."

Proganimate: Generate Java Codes from Flowchart

-----

Progranimate is a dynamic visualisation programming tool aimed at the novice programmer. Its aim is to make the initial stages of programming more palatable for the novice. Progranimate removes the complexities associated with novice exposure to professional development environments and the impact of writing syntax. This allows novices to focus solely on their key weakness, that of the algorithmic problem solving aspects of programming involving the basics of sequence selection and iteration.

Program Construction

Progranimate allows the users to construct a computer program via a flowchart based representation. The flowchart visualisations provide the novices with an accurate and useful mental model of the individual programming components and algorithms modelled.

Automatic Code Generation

Progranimate provides the novices with the ability to generate source code without being bogged down with the complexities of writing confusing and finicky syntax. Computer code is auto generated on the fly as components are added to a program. Progranimate can generate code in Java and Visual Basic with more languages planned for the future.

Code and Flowchart Highlighting

The highlighting of flowchart components and lines of code has been synchronised. This allows the user to draw a strong correlation between the flowchart and the textual code structure that such design would likely produce.

Program Animation

Programs can be animated with each step of a program being highlighted in turn in both the code and flowchart representations. Variables and array elements are visualised in the variable inspector. This allows the use to observe the effect that each program statement has on the values of the variables and arrays used. Progranimate's animation features and correlation it draws between the visual and code representations reinforce student understanding of both the visual solution and program statement flow

Online Integration

Progranimate can be used as a stand alone application. However, its can be integrated within a web page for concept demonstration, program demonstration or program creation. Progranimate can also be launched via Java web start. This means Progranimate can be used on any computer with internet access and the Java runtime environment. It also means Progranimate is an ideal centrepiece to an online tutorial involving the basics of programming for novices.

RAPTOR: Flowchart-based programming environment

-----

RAPTOR is a flowchart-based programming environment, designed specifically to help students visualize their algorithms and avoid syntactic baggage.  RAPTOR programs are created visually and executed visually by tracing the execution through the flowchart.  Required syntax is kept to a minimum.  Students prefer using flowcharts to express their algorithms, and are more successful creating algorithms using RAPTOR than using a traditional language or writing flowcharts without RAPTOR.

Click here to see a picture of RAPTOR.  For a paper describing the use of RAPTOR in a general education course, click here.

Download

Where/how are you using RAPTOR?   I keep a list of what schools and universities are using RAPTOR and for what class.  This helps me plan future advancements.  Please email me and let me know.

 NOTE! The installer was signed with a US Department of Defense certificate. You can get the root certificates from DoD Class 3 PKI Root Certificates

Portable Version

John Meir from Midlands Tech created a Portable App version (PortableApps.com). This allows RAPTOR to be used from a USB key or similar without installing. You can download the portable versionhere.
