Out-of-class Activity Design - 3 Aligning Assessment with Learning Objective Learning Objective Assessment Strategy Expected Duration (in min) Additional Instructions (if any) Merits and demerits of concrete Q1.What are the merits of concrete Q2. what is meant by high performance concrete 10 minutes Watch V1 and then answer Q1 and Watch V2 and then answer Q2

Out-of-class Activity Design - 3 Aligning Assessment with Learning Objective Learning Objective Assessment Strategy Expected Duration (in min) Additional Instructions (if any) Performance of concrete Q. Designation of normal strength of concrete 10 minutes Submit answers to all questions 3 hours before coming to class. Total activity duration 30 minutes

In-class Activity Design -1 Learning Objective(s) of In-Class Activity At the end of the class, students will be able to, Learn the composite materials of concrete like cement, sand, aggregate and admixtures (Understand Level) How Strength of concrete affect the quality of concrete (Apply Level) Key Concept(s) to be covered Admixtures Types of cement

In-class Activity Design -2 Active Learning activity(ies) that you plan to do Real world problem solving using. Latest construction materials Whether admixtures helps in increasing the strength of concrete Concept clarification using. The strength of concrete can be obtained by i. use the mix ratio with respect to design mix ii. Proper manpower iii. Use of quality material iv. Proper supervision

In-class Activity Design -2 Peer Instruction Strategy – What Teacher Does Pose the two PI questions at the start of the class and provide summary of basic identities and expression simplification. Q 1: The quality of of concrete depends on, A.single sized aggegates B.two sized aggregate C.graded aggregatese D.coarse aggregates.

In-class Activity Design -2 Peer Instruction Strategy – What Teacher Does  Q 2: Long period of curing in concrete ensures better A.volume stability B.Strength C.water resistance D.water tightness and durability E.all the above.

In-class Activity Design -2 Peer Instruction Strategy – What Student Does Individual response from the student are very theoretical for the questions Discuss with peers and come to consensus : After discussion students have vast knowledge with the aggregate and curing concept. Instructors Explanation: Normally the graded aggregates are used and the students will learn from the theory part itself as graded aggregates will properly bond between all other composite materials. the answer all are similar and also all the answer option are correct volume stability, Strength water resistance, water tightness and durability.

In-class Activity Design -2 TPS Strategy – What Instructor does For concreting the usage of Manufacturer-sand is advisable or river sand is the best one? Whether the usage of admixture is advisable in workability of concrete?

In-class Activity Design -2 TPS Strategy – What Instructor does Gave 2 minutes for think: Student have knowledge about the Manufactured sand and river sand. The workability of concrete. Instruction: Manufacturer sand used as a component for concrete and the

In-class Activity Design -2 TPS Strategy – What Instructor does Pair (~5 minutes) The students are grouped in Instruction: Now pair up and compare your answers. Agree on one final answer. While students are pairing and discussing, instructor goes to 2~3 sections to see what they are doing. Now assuming that two variables A and B, as shown in table, are used to select sensor output based on time, develop a Boolean expression to combine time selection and output selection. i.e. A,B and output (T+H)

In-class Activity Design -2 TPS Strategy – What Instructor does Sharing ideas of students: The students shared their ideas in workability and usage of M-sand in concrete Students had different opinions in usage of M sand as it is not like natural river sand is it advisable to use in concrete. Also the government also refer to use M-Sand. If the quality of the M sand is upto the mark like river sand we can use the M sand. In workability the admixtures now play a major role as many of the concreting are done by Ready mix concrete so the admixtures can be used. The percentage of admixtures used have to fixed by trial mix.

In-class Activity Design -2 Justify why the above is an active learning strategy In both the above strategies, students are required to go beyond mere listening and execution of prescribed steps. They are required to think deeply about the content they were familiarized in out-of-class and dcco higher order thinking. There is also feedback provided (either through peer discussion or instructor summary) Instructor given a practical exposure related to the workability of concrete using slump cone test.
