Target Student Population:: Grade School, High School, College General Ed, College Upper Division, Graduate School, Professional
Prerequisite Knowledge or Skills:: Basic knowledge of physics.

Rating:
Strengths:: The video presents how heat exchangers and mixing chambers work. The video deals with the heat transfer process between fluids at different temperatures, even without or with mixing. It describes the main features of heat exchange, applying mass and energy conservation. Three examples are included. Contents are presented in a clear and concise manner. The contents are core concepts in basic thermodynamics in engineering courses. Information is provided accurately and summarizes well the main ideas.
Concerns:: The resource is passive, lacking interactive elements (quizzes) for learners to self-assess their understanding in real-time.

Rating:
Strengths:: The material could be used for self-learning as well as a supplementary material in traditional or blended/hybrid courses on basic thermodynamics. The learning objectives are clearly stated. Physical phenomena and explanations concerning the work of heat exchangers and mixing chambers are presented using text, pictures and animations, easy to understand. In includes equations explaining the relation between the main parameters involved in the transport of heat between fluids that improve the video.
Concerns:: No concerns.

Rating:
Strengths:: The presentation is a standalone material, easy to use. Only connection to the Internet and link to the video repository is needed. It can be reproduced in computer, iPad and smartphone. Visual design of the presentation corresponds to a succession of pictures as the explanations are given.
Concerns:: As corresponds to video materials, limited interactivity.
