Ulcers on the cornea (the clear window covering of the eye) can occur if contact lens are worn while sleeping, if they are not cleaned properly, or if you do not wash your hands well before touching your contacts. Corneal ulcers are usually caused by an infection with bacteria, viruses, fungi, or a parasite. Although you can recover completely from a corneal infection, it may also cause long-term damage to the cornea and loss of vision
Assessing Behaviors in PBL/CBL Projects
To assess certain team and individual behaviors, you may want to develop sets of "rubrics," or scoring guidelines.
Using Rubrics to Assess Team Responsibility
For example, you may want to assess team responsibility by observing whether the team is
(1) solving its problems itself,
(2) asking each other before asking the teacher,
(3) helping other teams, classmates
The rubrics for item (1) solving, might include the following scorable attributes:
4 The team tries to solve its problems by itself, without seeking outside help.
3 The team generally tries to solve its problems by itself, but sometimes asks for outside help
2 The team seldom solves its problems as a team and usually asks classmates or the teacher for help.
1 The team seldom solves its problems and gives up easily.
0 The team never attempts to solve its problems and gives up readily.
You can create rubrics for items 2-3 modeled after the rubric provided above for item (1).
Using Rubrics to Assess Individual Responsibility
You may also want to assess whether members demonstrated individual responsibility for teamwork by
(1) listening to others,
(2) helping teammates,
(3) making polite requests,
(4) not being negatively critical toward teammates
The rubrics for item (1) listening, might include the following scorable attributes:
4 It is obvious that the student actively listens to and values the opinions of others.
3 The student actively listens, but it is not evident that he/she always values the opinions of others.
2 The student sometimes listens to and sometimes values the opinions of others
1 The student rarely listens to others and does not use their ideas or input
0 The student does not listen to and does not value the opinions of others.
You can create rubrics for items 2-4 modeled after the rubric provided above for item (1).
