Technology Enhanced Learning (TEL) is a new pedagogical domain aiming to study the usage of information and communication technologies to support teaching and learning. The following study investigated how this domain is used to increase technical skills in Computer Science (CS). A Delphi method was applied, using three-rounds of online survey questions, given to 17 TEL experts from different European countries. The results showed that these experts consider TEL an effective and interesting support to acquire CS skills. Furthermore, the findings revealed the five best tools in TEL to acquire necessary CS knowledge. Future research can provide a guideline to implement effective TEL tools in CS studies. This manuscript investigates Technology Enhanced Learning (TEL) tools and its applications to learn specific skills in CS. As general content the results of a Delphi study that identifies the benefits of TEL while teaching are highlighted.
