Assessment of Outcome Objectives
The course grade will be determined by the individual instructor (under the guidelines of the division) using a variety of methods such as quizzes, homework, group projects and exams. Graded activities are designed to measure students' abilities to use higher order thinking skills in their understanding and applying of hydraulic concepts. A comprehensive final exam is required. This exam must count for no more than 25% of the course grade.
Divisional Assessment
FIRE 2911 will be assessed every 5 years in the fall. The committee will develop a time-line to monitor the assessment process during the five year cycle to ensure that assessment activities are occurring in order to have sufficient data to undertake a formal assessment at the end of the cycle. Assessment will consist of:

a. An attitudinal survey addressing students' career and professional goals and perceptions of the quality and usefulness of the course.
b. A set of objective test items keyed to expected learning outcomes. These items will be balanced with respect to content and level of cognitive demand.
c. A pilot administration for the objective assessment instrument. The results of the pilot assessment will be used to determine how well the test items are functioning in terms of discrimination, difficulty, and test reliability. The information obtained from item analysis will be used to eliminate or rewrite test items not functioning properly.
d. The revised assessment instrument will be administered during the assessment cycle at a time established by the committee.
Use of Assessment Findings
The FIRE 2911 Assessment Committee will analyze the results of both the pilot testing and the formal assessment data as well as the attitudinal survey. The committee will use assessment results to determine the effectiveness of the course by seeking answers to the following questions:
a. Are students performing at a pre-determined minimal level of performance on:
1. the course as a whole?
2. on individual learning outcomes?
b. Which learning outcomes are students' performance acceptable or above average?
c. Which learning outcomes are students' performance below minimal level of performance?
d. What factors are contributing to student performance on those learning outcomes below minimal level of performance?
e. What changes or modifications in course content or instructional strategies are needed to help improve student performance on learning outcomes below minimal level of performance?
