Critical thinking and problem solving abilities are recognized as fundamental and crucial abilities in teaching science concept. The current study aims to explore undergraduate engineering students’ critical thinking and problem solving skills. In addition, their problem solving and puzzle-based learning abilities were examined. Data were collected from 139 freshman students enrolled in different engineering department including Mechatronic, Civil, Electrical and Electronics, Biomedical, Industrial, Computer and Metallurgical and Materials engineering during Spring semester of 2013. In terms of gender, majority of them (N= 94) were male and % 33 (N=46) were female. In conclusion, findings revealed that most of the students lack of employing critical thinking and problem solving skills and are not prepared for puzzle-based learning science activities.
