Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.
6 Three ultimate goals are ideally reached through learner-centered strategies: 1. The development of inquiry and problem-solving skills 2. The development of a deep understanding of topics 3. The development of democratic processes (e.g., critical examination of our own and other's positions) 4. As part of a continuous improvement process and to conform to IACET standards, NHI has instituted a course design policy to include a post-course assessment. Selection of this learning evaluation tool is an ISD decision and is designed to measure participant performance with the course learning outcomes. Acceptable tools include case studies, skills demonstrations (workshops), and objective tests. SCOPE AND APPLICATIONS OF THE TRAINING MANUAL The Training Manual was developed as a standalone document to support the NCHRP Project 24-47 Implementation Plan. The Training Manual provides a companion workshop that incorporates lesson plans, photographs, and videos to provide training on the revised contraction scour methodologies. This deliverable meets all current ISD standards established by FHWAâs NHI and after review and approval by NHI could be incorporated into NHI course offerings as additional or optional workshops. Moreover, the contraction scour workshop provides the basic instructional components for the development of a distance learning (web- based) presentation at some time in the future. The 390-minute workshop lesson development adheres to the guidance promulgated by NHI and the IACET for adult learning. The workshop is organized in modular fashion to support presentations in various venues, including a mini-workshop at conferences, such as the Transportation Research Board (TRB) Annual Meeting, American Public Works Association (APWA), American Society of Civil Engineers (ASCE), FHWAâs National Hydraulic Engineers Conferences, and others. TRB (via NCHRP) may also choose to make this material available on an expedited basis to state highway agencies and bridge owners who could use it for in-house training of department of transportation (DOT) hydraulic engineers and their consultants. The modular organization of the workshop would support presentations of 1, 2, or 3 hours as well as the full 6.5-hour format. The seven Sessions of the workshop (presented in two Parts) include the following topics and are designed to achieve the following user-oriented, performance-based learning outcomes.
7 Part I Topics ⢠Contraction hydraulics and scourâcurrent practice ⢠Evaluation of existing laboratory and field data Learning Outcomes At the end of Part I, Participants will be able to ⢠Describe contraction hydraulics and scour, and current evaluation techniques. ⢠Identify the quality and shortcomings of existing laboratory and field data. Part II Topics ⢠NCHRP Project 24-47 laboratory and computational analyses ⢠Revised contraction scour methodologies (clear-water and live-bed) ⢠Group Workshop on the application and appraisal of the revised methodologies Learning Outcomes At the end of Part II, Participants will be able to ⢠Describe the laboratory and computational techniques used in NCHRP Project 24-47. ⢠Discuss and evaluate the revised contraction scour methodologies developed under NCHRP Project 24-47. ⢠In a Group Workshop setting, apply the NCHRP 24-47 methodologies for a single span bridge under live-bed contraction scour conditions. ⢠Compare the reliability of the revised contraction scour methodologies with current techniques.
