The Indonesian government has directed the abilities of Indonesian students towards the 4C skill (creativity, critical thinking, collaboration, and communication) since 2013. PjBL-based students’ worksheets will be able to encourage the 4C's skills; while still adopting Technological Pedagogical and Content Knowledge (TPACK) and Higher Order Thinking Skills (HOTS). The current research aimed to implement and evaluate design concepts and develop PjBL-based students worksheet that has been adapted to teaching materials to improve the 4C skill of Senior High School students in English subjects. The PjBL-based students’ worksheet was developed by matching the criteria for the components of the student’s worksheet model, namely: model syntax, social systems, management reaction principles, support systems, instructional impacts, and accompaniments, as well as other necessary instruments. The instruments developed were in the form of a student worksheet model validation sheet and learning tools validated by experts and practitioners. This research resulted that PjBL-based students’ worksheets are needed to be developed for English language teaching to cope with the 4C skill of Senior High School Students.
