SUGGESTED SPECIAL INSTRUCTIONAL STRATEGIES (if any)
These are sample strategies, which the teacher can use to accelerate the attainment of the various outcomes in this course:
- Massive open online courses (MOOCs) may be used to teach various topics/sub topics.
- L in item No. 4 does not mean only the traditional lecture method, but different types of teaching methods and media that are to be employed to develop the outcomes.

- With respect to item No. 10, teachers need to ensure to create opportunities and provisions for co-curricular activities.
- Guide students in undertaking micro-projects
- Use Flash/Animations to explain various theorems in Geotechnical Engineering.
- Demonstrate various concepts related to Geotechnical Engineering .
- Encourage students to refer different websites to have deeper understanding of new concepts of Geotechnical Engineering.
- Assign unit wise tutorials to group of 4 to 5 students for solving problems unit wise.

- Use of video animation films to explain concept, Facts and applications related to Geotechnical Engineering .
- In respect of item 10 above teacher needs to ensure to create opportunity and provisions for such co curricular activities.
SUGGESTED MICRO-PROJECTS
Only one micro-project is planned to be undertaken by a student that needs to be assigned to him/her in the beginning of the semester. In the first four semesters, the micro-project are group-based. However, in the fifth and sixth semesters, it should be preferably be individually undertaken to build up the skill and confidence in every student to become problem solver so that s/he contributes to the projects of the industry. In special situations where groups have to be formed for micro-projects, the number of students in the group should not exceed three. The micro-project could be industry application based, internet-based, workshopbased, laboratory-based or field-based. Each micro-project should encompass two or more COs which are in fact, an integration of PrOs, UOs and ADOs. Each student will have to maintain dated work diary consisting of individual contribution in the project work and give a seminar presentation of it before submission. The total duration of the micro-project should not be less than 16 (sixteen) student engagement hours during the course. The student ought to submit micro-project by the end of the semester to develop the industry oriented COs. A suggestive list of micro-projects are given here. Similar micro-projects could be added by the concerned faculty:
- Write a report on role of a geotechnical engineer in civil engineering practice.
- Taking the samples in field and test it in laboratory for different properties of soil.
- Calculate the bearing capacity of soil from the Atterberg limit values.
- Compute the plasticity index and toughness index for the given soil sample from given data.
- Select a soil sample from given one which contains more clay particle, has group saturated unit weight, has a greater dry unit weight, has a greater void reatio.
