1 Innovative practice: JIGSAW Cooperative Learning Technique
1.1 Topic:
Develop web service application for implementing online Airline Reservation Systems. The
system includes the following SOA components and principles.
1. Web services & WSDL
2. SOAP
3. Message Exchange pattern
4. Web service Activity
5. Coordination service
6. Orchestration
1.2 Learning objectives
 To encourages cooperative learning among students.
 To improve listening, communication, creativity and problem-solving skills.
1.3 Procedure:
Step 1
 Divide students into 6-person Jigsaw groups
 The groups should be diverse in terms of gender, ethnicity, race, and ability.
Step 2
 Appoint one student from each group as the leader.
 Each student in a group given a number from 1 to 6
Step 3
 Divide the course contents (unit) into 6 segments
Step 5
 Give students time to read over the course content’s segment.
Step 7
 Bring the students back into their jigsaw groups

2. Step 8
 Ask each student to present her or his segment to the group.
 Encourage others in the group to ask questions for clarification
Step 9
 Float from group to group, observing the process
Step 10
 At the end of the session, give a quiz on the material
1.4 Design and Implementation
 Procedure of Jigsaw activity posted in the course website in advance in which
students knew the knowledge of this activity.
Followed the Step 5
 Divide students into 6-person Jigsaw groups
Followed the Step 5
 Form temporary “expert groups” by having one student from each Jigsaw group
join other students assigned to the same segment.
 Some clue about the course contents given to each expert group when they were
discussed the segment that used to remember the student about the topic

3. Followed the Step 7
 Bring the students back into their jigsaw groups.
 Then, asked each student to present her/his segment to the group and encourage others
in the group to ask questions for clarification
At the end of the session, quiz was given to assess the students.

4. Glimpse:
1.5 Challenges and strategies:
 Make the slow learner participation in the activity
 To form the heterogeneous group (male and female).
 Motivate the slow learners to involve the activity.
 Given clue about the content while doing the activity
1.6 Observations:
The Jigsaw technique is designed for cooperative learning in small groups. Students
are provided the opportunity to become experts in a particular content, and share that
knowledge with their peers. This technique promotes both self and peer teaching which
requires students to understand the material at a deeper level and engage in discussion,
problem solving, and learning
Students are interested to involve the activity. The Jigsaw technique helps the students
to develop expertise in a particular topic and practice self and peer teaching.
1.7 Students Response:
 Students got comfortable after form a group with their friends and done brainstorming
with their team members about the segments actively.
 Bright students were actively participated to prepare the web services and SOA
principles.
 Slow learners expect to assist the content development.
 Most of the students were enjoyed the session.
Students response ensures the students could improve listening, communication, creativity
and problem-solving skills.

</add>
</soap:Body>
</soap:Envelope>

8. SOAP output message (Service provider)
<?xml version="1.0" encoding="utf-8"?>
</soap:Envelope>
<soap:Body>
<addResponse xmlns="http://tempuri.org/">
