Contribution of course to meeting the professional component

This course contributes primarily to the students' knowledge of engineering topics, and does provide design experience.

The following statement indicates which of the following considerations are included in this course: economic, environmental, ethical, political, societal, health and safety, manufacturability, sustainability.

environmental issues related to timber harvesting

Relationship of course to undergraduate degree program objectives and outcomes

This course primarily serves students in the department. The information below describes how the course contributes to the undergraduate program objectives.

The course supports practical design instruction that is most useful in structural and construction engineering. The information below describes how the course contributes to the undergraduate program objectives. CEE Outcome #1: CEE students should be able to use the engineering design process for creative CEE problem solving. Course: Design principles and the role of assumptions are learned. Unconventional problems are often assigned as homework to develop these skills. CEE Outcome #7: ...ability to apply knowledge of mathematics and natural science to CEE problems. Course: Becaise of the nature of wood structural design and the biological nature of wood, math and, to a lessor degree, natural science skills are exercised in the course. CEE Outcome #8: ...recognize the non-technical factors in engineering decision making... Course: Environmental issues related to timber harvesting are one example of non-technical factors that are discussed. CEE Outcome #10: ...life long learning. Course: Technical resources including web pages and other design aids are referenced and discussed to extend learning beyond the timeframe of the class room. CEE Outcome #11: ...should know physical properties that describe fundamental behavior... Course: Fundamental nature and properties of wood materials comprise a major portion of the course. CEE Outcome #13: ...recognize common failure mechanisms... Course: Failure of wood components from overload and durability are learned and anecdotal examples are provided during lectures.

Assessment of student progress toward course objectives

Students are primarily assessed through the homework and exams as weighted: Homework - 20% In-class exam 1 - 20% In-class exam 2 - 25% Final exam - 35%.

Formative assessment is conveyed both through posed questions in lecture and through discussion during office hours.

Course assessment is addressed through course evaluations, exam results, and discussions with students during the semester.
