The Triangular World _ PBL WRAP-UP


Name of the Teacher : USHA A P
Class : 10th

A brief report on the implementation of the  phases of PBL

The ‘what/ when/ where/ how’ of the  phases of PBL in brief

Define Phase

The purpose of the project is to develop a strong base in trigonometry and at the same time gain practical experience of using it in daily life situations such as determining the heights and distances of objects and further more to investigate the application of trigonometry in Science and technology.

Plan Phase

Created curiosity among the students through questioning. “Can you find the height of a tall tree with the help of a page of notebook?”
Divided the class to seven heterogeneous group and assign projects to each group which are as follows :
Group 1 : Find Area of a Triangle when two sides and included angle are given, Application of Trigonometry in other chapters of the textbook.
Group 2 : To prove angle of elevation is equal to angle of Depression.
Group 3 : To find the Sun’s Elevation at Constant intervals and use the concept to find the height of any tall object in the campus.
Group 4 : To find the height of any two tall objects by measuring the angle of elevation.
Group 5 : To find the height of the building by measuring the angle of elevation from two points separated by a known distance.
Group 6 : To find the height of a tall object by measuring the angle of elevation from two different heights.
Group 7 : Application of trigonometry in different fields of Science and Technology and also in our daily life.
Prepared Rubrics and parameters for Authentic assessment.   

Plan Phase

After the Launch and instruction, each group was made to perform the following Tasks
·         Research (Online and books)
·         Hands-on Activity
·         Power Point Presentation
·         Seminar
·         Exhibition
·         Blog creation

After briefing, different roles were defined
Mentor: The Teacher
Researcher:   All members
Performer of Activity:  Every Member
Recorder: The assigned member in each group.
ICT leader: The computer expert in the group.
Compiler: The Coordinator of the group.
Presenter:  The one (or a  group)who Presents the seminar
      Blogger: The ICT experts in the class.

A task schedule was charted and special activities such as Guest lecture,  Exhibition and
Blog creation was carried out.

Reviews and Need-based meetings were conducted to update project status.

Rubrics were defined and an assessment plan based on it was prepared which is as follows :
·         Hands-on activity and its report
·         Preparation of artifacts
·         Power point presentation
·         Utilization of Online resources
·         Seminar Presentation
·         Problem solving ability

Work Plan

A detailed Work plan was plotted allotting time schedules for each task/activity starting from 1.11.16 to 12.12.16 comprising the following :
·         Project Launch
·         Classroom Instructions
·         Group selection
·         Activity
·         Guest lecture
·         Record maintenance
·         Seminars and talks
·         Advice meeting
·         Project presentation
·         Assessment and grading
·         Reflection and evaluation
·         Project closure

Do Phase

The topic for project is announced in the class. An outline of the Action plan is prepared counting the suggestions from the students’ side. The main topic is divided into sub topics and distributed among the seven groups.  A detailed discussion on tasks, subtasks, performing the activity, materials to be prepared, online research, report making, completion of project etc. was carried out.
List artifacts created during the project :
1.      Clinometer
2.      Activity Report
3.      Power point   presentations
4.      Charts
5.      Project report

Review Phase

Student Reflection and Evaluation:
Discussion on the progress of the project every day during Maths period was carried out. Suggestions and modifications were done at every stage. Both Individual and Group performance were evaluated by the other groups.

Teacher Reflection and Evaluation:
Evaluation of the involvement of each student and the assessment of the standard of the end-product was carried out.
The evaluation was done as per the rubrics prepared. The strategy adopted for the  execution of the project, the final Project Record, and the presentations by the students, the standard and appropriate usage of artifacts, the uploading of materials in the created blog were some of the areas assessed.
Content standards, higher order thinking skills, attitude and application level skills were also evaluated.
21st Century skills were incorporated in areas wherever possible throughout the course.

Manage Phase

The following tasks were used to manage the process of conducting the learning
·         Research on the topic (online & offline)
·         Making clinometer
·         Finding angle of elevation and depression
·         Group Presentations
·         Solving Textual problems
·         Blog
As a part of student preparation, students were made to revise the concept and understand the different parameters and their mode of application in their specific tasks. 
The different resources such as classroom, Computer Room, Maths Lab, Library and LCD room were utilized during the project. Project progress was monitored frequently and re-planning was done wherever necessary.

The reports and the photos of the activities done by the groups were compiled and uploaded on a blog Trigonophilia - As the name of the Blog suggests, a mode change from Trigonophobia to Trigonophilia in the students’ attitude was observed. The group work, Peer learning, Learning through doing helped them a lot in making the concept thorough. Exposure to technology inspired them to go beyond the text and acquire additional knowledge regarding the subject. This has been a very good platform for the students to advance and develop much needed skills such as leadership qualities, peer management and team work which are needed for today’s competitive world. This scheme has provided the students to diligently do research opening a scope for “out of the box” . It has opened a new perspective about the subject for them which would have been difficult in the typical teaching methods. On the whole, this was an amazing experience that many are eagerly waiting for the next venture.
