A systematic review procedure was developed and applied to detect and subsequently review relevant research studies published from 2010 to 2019. The current study conducted a systematic literature review to analyze research studies that conducted investigations related to implementations of CS unplugged activities. The computer science (CS) unplugged approach intends to teach CS concepts and computational thinking skills without employing any digital tools.

Grandparents also help to keep their grandchildren focused and augment the grandchild's problem solving. Grandpar- ents and grandchildren work together on a single platform, allowing grandchildren to illuminate their grandparents understanding of programming. Students are provided a workstation and Lego Mindstorms NXT 2.0 robot, configured as the humanoid robot 'Alpha Rex' ( Figure 2), for these programming exercises. Both Mindstorms software use a visual programming paradigm similar to Scratch 2, allowing users to arrange programming blocks in a sequential or parallel fashion in their workspace.

The fourth year used the newer, but similar, Lego Mindstorms EV3 environment. In the first three years of the class, all programming exercises were conducted in the Lego Mindstorms NXT 2.0 devel- opment environment. the second day of class, we guide students through a series of five programming exercises that teach students basic concepts in computer science and how they can use these concepts to develop social robots.
