Introduction

This is a material, designed to demonstrate the functionality of the tools available within this platform.

The idea is that the user should simultaneously open the source code and the output of the material and learn the fwiki markup language by comparison between the code and the output.

To facilitate that, the code of successive slides is separated by long vertical spaces (many empty lines), and various parts of the code of one slide, like conditions for different paths and different feedbacks are also separated by shorter spaces and comments.

In the code, comments are marked by a !-- for a comment to the end of the line (the line may be wrapped, but it is still one line) or by [!--  --] for multiline comments.

Not all functionality is used in this sample, and some functionality already included is still being developed. The material is planned to be updated as new relevant functionality becomes available.

There may be other tutorials and help materials on the site, perhaps some are translated to English. We wish you good work.

Single choice, button version

Choose the correct answer.

The shape is a triangle.
The shape is a rectangle.
The shape is a circle.

Correct

Congratulations, the answer is correct.

The main feature of the shape is that it has three angles. That is reflected in its name, therefore it is called a triangle.

Correct

Congratulations, the answer is correct.

The main shape-related feature of the shape is that it has three angles. That is reflected in its name, therefore it is called a triangle.

Light reflected from the object when exposed to the visual spectrum in mainly in the region defined as color red. Therefore we say the shape is red.

Next

Incorrect

Unfortunately, incorrect.

The main shape-related feature of the shape is that it has three angles. That is reflected in its name.

Color is defined via the wavelength of the light emanating from an object. By that definition, cloudless sky by day is blue, grass and most leafs are green, sun is yellow, and cloudless sky around the sun at sunset is red.

Try again.

Next

Incorrect

The picture shows just one shape, so you should choose just one of the shapes from the list.

Close

Incorrect

The shape is of only one color, so you should choose only one color from the list.

Partially correct

The answer is partially correct.

You have correctly identified the shape. The shape has three angles so it is called a triangle.

You have not correctly identified the color. Color is defined via the wavelength of the light emanating from an object. By that definition, cloudless sky by day is blue, grass and most leafs are green, sun is yellow, and cloudless sky around the sun at sunset is red.

Close

Partially correct

The answer is partially correct.

You have correctly identified the color. Light, emanating from the shape is mainly in the region defined as color red. Therefore we say the shape is red.

You have not correctly identified the color. The main shape-related feature of the shape is that it has three angles. That is reflected in its name.

Reading from a graph

Next

Measuring distances and drawing lines

Currently the tool can only be used to measure distances. The attribute "unitFactor" determines the pixel/unit ratio.

In the future, it should be possible to click the check button on the line and it will be possible for the computer to automatically process the
- length of the line,
- the measured distance,
- the beginning and
- the ending point.

Vectors

At the moment vectors can only be drawn, but shortly it will be possible to click on the check button on the vector and the program will be able to check the values of length, angle, start point and end point by itself.

Freehand tool

Test

NOTE: The freehand tool can not (yet and in the close future) be evaluated by the program. All you can do is to send the picture as a result to the evaluator, who must then evaluate it. Just like an essay question.

Next

Polyline tool

NOTE: At the moment the polyline is derived from an angle tool. Shortly it will be redesigned as a separate tool.
After starting the tool, click anywhere on an arm and a new point will appear.

Test

Next

The polyline tool will return coordinates of each point, and maybe length and angle of each segment. The start point will always be the leftmost end. In case both ends are equally left, the start will be the uppermost of the points.

We imagine the tool can be useful for drawing simple graphs like a combined motion made out of uniformly accelerated and constant velocity segments.
