This paper presents the assessment of a continuous assessment in a project for the Dynamics subject using an analytic rubric. Dynamics subject should improve the ability of students to evaluate and solve problems using well-understood basic concepts implemented in a simple logical manner. It focuses on the proper interpretation and application of the concepts of mechanics to the solution of engineering problems. To achieve the objective of being able to examine the issue of mechanics, students were asked to prepare a poster that must consist of the real-life application of dynamics, which they must incorporate in the sense of their poster the definition plus the use of basic fundamental principles. An analytic rubric was used as a scaffold in the evaluation of the continuous assessment of undergraduate students of civil engineering in the Dynamics subject. The continuous assessment referred to was the evaluation of a project called 'Poster Dynamics in Life.' Using analytic rubrics, lecturers in this engineering subject (Dynamics) may specifically list evaluation criteria to improve the synchronization of learning, instruction, and assessment. Besides, students may then use the rubric to organize their assigned project, describe goals, define and concentrate efforts where appropriate, identify concerns relevant to the project, and control the process in an attempt to construct a high-quality project. The results from this assessment show that most of the students achieved all the performance criteria at an acceptable level.
