There has recently been a renewed interest in integrating computational thinking skills into the school curriculum. Still, much remains to be done to understand the convenient ways to introduce them to young students. This research aimed to study the effects of WeDo 2.0 robot workshop on grade five students' acquisition of the computational thinking concepts (CTCs) and their acceptance of the robot technology used. A quasi-experimental method, One-Group Pretest-Posttest design, was adopted to achieve the research objectives. The sample consisted of thirty-five male and female students aged 11-12 years. The experimental group (n = 35) participated in an informal five days' robot workshop held in the Science and Technology Centre in Al-Dakhliya region. Students got four hours of daily training for five days (A total of 20 hours) on the computational thinking concepts using WeDo 2.0 robot. Data were collected using two instruments: (1) pre-post computational thinking concepts test (2) Technology Acceptance questionnaire. The pre-posttest was implemented to measure students' acquisition of computational thinking concepts (CTCs). The test consisted of 16 questions and aimed to assess the students' understanding in three dimensions of the computational thinking concepts (CTCs): Sequential control flow, Loops, and Conditionals. Seven experts determined the pre-posttest content validity, and the internal consistency reliability (an alpha coefficient of 0.73) of the test was measured before using it. The questionnaire was implemented at the end of the training workshop to measure students' acceptance of robot technology using an extended Technology Acceptance Model (TAM). Data were analyzed using the Statistical Package for the Social Sciences (SPSS) software. The findings of the study showed a significant improvement in grade five students' acquisition of CTCs after attending the robot workshop and a positive acceptance of robot technology. In light of the research findings, implications and recommendations for future research were outlined.
