Text: Dear Dr. Scratch Team,<br>
<br>
My name is Esra Cakiroglu, and I am currently a student at RWTH Aachen University (Germany), studying Computer Science Education (Informatics for future teachers).<br>
I am in the process of writing my Master's thesis, which focuses on assessing the Computational Thinking competences of secondary school students. For this purpose, I have developed my own measurement instrument, and I also plan to evaluate the Scratch projects created by the students.<br>
<br>
While searching for tools to assist in the evaluation, I discovered your platform Dr. Scratch, which I find very helpful and thoughtfully designed.<br>
However, I have a few questions and I hope you might be able to assist me:<br>
<br>
I could not find detailed documentation explaining how exactly projects are classified into different competence levels (for example, when a project is labeled "Master").<br>
Could you kindly provide information on:<br>
<br>
What competence levels exist in Dr. Scratch,<br>
<br>
How many points are needed to reach each level,<br>
<br>
And how these levels are defined?<br>
<br>
Additionally, it would be very helpful for my research if you could clarify a few further aspects:<br>
<br>
Is there any weighting between the different dimensions (e.g., Logic, Flow Control, Data Representation) when calculating the final score?<br>
Are there any scientific publications or internal guidelines that describe the development, calibration, or validation process of Dr. Scratch?<br>
<br>
I would be very grateful for any information you could share. Your answers would greatly support the theoretical foundation and evaluation design of my thesis.<br>
<br>
Thank you very much in advance for your time and help!<br>
<br>
Best regards,<br>
