abstract

Malaysian Ministry of Higher Education has outlined an integrated Cumulative Grade Point Average to be implemented in universities. Among attributes that being evaluated are teamwork, leadership, and communication. The best way to evaluate this attribute is by peer evaluation after each task is completed. Evaluating using traditional way is non-economical and quite cumbersome. There is also possibility of students evaluate another student that they should have not. Another problem is that students would not get any feedback to improve themselves afterwards. The objectives of this study are to design a web application that have interactive and intuitive user interface which easy for user to understand and use. Secondly, to develop a system for a student to rate their peer’s contribution in team and detect anomaly rating from student using Tukey Method. Finally, to evaluate the functionality of the developed application that meets the requirement. Tukey method is used in this system to detect bias rating from a peer to a student. It working by detecting outlier number from the data set and point out the number which is much lower or higher than most numbers in the data set. The main technologies that being used in this project are PHP and MYSQL databases. By the end of this study, it is expected that the developed system can allow a student to rate their team member’s contributions numerically, give written feedback to their peers, receive feedback of their teamwork performance and detect anomaly rating from the data set. In conclusion, this application will help student to learn their level of teamwork performance and then enhance their soft skill to perform better in next task.

PROJECT BACKGROUND

Teamwork involves people working collaboratively together as a team for a common goal or purpose which involves students to working actively and collaboratively on specific tasks in a range of settings. The final outcome from the project affects each individual’s grade. Individual grades are formed from the combination of individual and team performance on exams, assignments and the completed project. The individual performance of a member can be evaluated by exams and in some way by assignments. However, it is sometimes difficult to evaluate the contributions of the member to the team and the project. Assessments of team member’s effort can be evaluated by peer evaluation.

To know being evaluated by peers causes an increase in the performance of teams. Earlier studies show that blind peer evaluation systems may decrease the inflation effects on assessment. There are indications that students’ performance evaluations of their peers are affected by whether they also do self-assessment. However, many issues have been raised about students’ anxieties and doubts concerning the fairness and effectiveness of peer assessment. These issues range from unfairness, favoritism, collusion, to personal hatred and complexity. 
​
Therefore, Peer Evaluation System for Assessing Teamwork Performance Using Tukey Method aim to ease instructor generate marks for peer evaluation session. The marks that have been generated by this system can be used to give feedback for students about their performance in the team. In addition, it can also be used by teachers for students scoring purposes. Lastly, it also can reduce biasing by detecting unusual data in the data set.

problem statement

  • ​​PLO5 in iCGPA rubrics relate with student’s teamwork skill assessment which need their teammates to evaluate their performance.
  • It was unfair to give equal mark for unequal contributions in group task.
  • Student give bias review for their peers.
  • It’s take a lot of time and effort to calculate student’s individual score.

OBJECTIVES

to design

To design a system which have interactive and intuitive user interface which easy for user to understand and use.

to develop

To develop a system for a student to rate their peer’s contribution in team and detect anomaly rating from student using Tukey Method .​

to evaluate

To evaluate the functionality of the developed system that meets the requirement.

SYSTEM FRAMEWORK

  1. Student rate their teammates in peer evaluation
  2. System generate mark for student using mean calculation and Tukey method to detect outlier number
  3. Instructor will get Peer evaluation score for the whole class and also outlier  report.
  4. Student will get their individual score for that peer evaluation.

 ALGORITHM & TECHNIQUES USED

aRITHMETIC mEAN

Arithmetic Mean Calculation was used to calculate the average mark given by evaluators (their teammates).

TUKEY METHOD

Tukey Method is the added value in this system which will be used to detect bias rating (outlier number ) from any evaluators to a student.

RESULTS
  • Having A dynamic web layout.
  • Apply Regular Expression on form for validation.
  • Use AJAX to access server content.
  • Use JavaScript to access the DOM
  • Update HTML content via JavaScript​
  • use bootstrap
  • ​Using Mean Calculation to generate student score

CONCLUSION

"iCGPA need instructor to asses student’s teamwork skill.Student’s teamwork skill can be assessed their teammates.Peer Evaluation system ease instructor to asses their student and generate the result.Hopefully this system can be developed successfully and give benefit for student and teacher."
