Improved version
(Other versions can be consulted in the edit history of the answer)
Using the xkeyvalue package, this new version has a \EducNotebook command with a key-value system to control the attributes; the main features are:
The spiral can be drawn on top, to the left or to the right.
The user can select the number of spirals to be used.
The user can select a background color.
The user can include a major and/or a minor grid.
The colors for the grids can be independently selected.
A description of the available keys appears at the bottom of this answer.

Some examples
Using the default settings with \EducNotebook:

Moving the spiral to the top, changing the spiral number to 8 and adding a background color can be done with
\EducNotebook[
spiralposition=top,
spiralnumber=8,
nbcolorbg=cyan!10
]

Moving the spiral to the right (automatically the shadow shift sides), changing to 16 spirals, adding a background color, and a major and minor grids (you can also customize the grid colors), can be done with
\EducNotebook[
spiralposition=right,
spiralnumber=16,
nbcolorbg=yellow!10,
majorgrid=true,
minorgrid=true,
]

Available keys and their values
nbcolorbg=<color> applies as the background color for the notebook (default: white).
spiralposition=<left|top|right> selects the position for the spirals (default: left).
spiralnumber=<number> draws <number> spirals.
minorgrid=<true|false> activates (if true) the minor grid (default: false).
majorgrid=<true|false> activates (if true) the major grid (default: false).
minorgridcolor=<color> specifies <color> for the minor grid (default: black!20).
majorgridcolor=<color> specifies <color> for the major grid (default: black!60).
