7. Three Root Causes!!!!
O Students don’t take responsibility for themselves.
O Students are experiencing emotional or
psychological problems.
O There is no consequence to being late.
8. Three Root Causes!!!!
O Students don’t take responsibility for
themselves:
While the majority of students are responsible and mature,
there are some who struggle with the independence
college provides and who fail to do what they need to do
(e.g., set an alarm clock, allow sufficient time to get ready
in the morning, figure out the bus schedule) to get to class
on time.
9. Three Root Causes!!!!
O Students are experiencing emotional or
psychological problems:
Several psychological and emotional conditions can
undermine students’ motivation to get to class on
time. Indeed, a hallmark symptom of conditions such as
depression includes a decreased motivation to engage in
normal daily activities. In addition, prescription medications
can interfere with motivation and may disrupt sleep
patterns, which may indirectly affect students’ ability to get
to class in a timely manner.
10. Three Root Causes!!!!
O There is no consequence to being late:
The consequences associated with a behaviour help
determine whether or not that behaviour will be repeated. If
the consequences are negative, the behaviour is less likely
to reoccur. This applies to coming late to class. If
instructors fail to respond to or penalize lateness, or do so
inconsistently, the behaviour is likely to continue.
11. Solutions To Root Causes!!!
O Students to take responsibility for themselves:
1. Making the expectations explicit: Clearly and
unequivocally articulate your policy about lateness in your syllabus
and on the first day of class.
2. Encourage communication: Make sure students know
it is their responsibility to communicate with the authority if
they are experiencing a legitimate problem that will cause
them to be late or otherwise miss class time.
12. Solutions To Root Causes!!!
O Students are experiencing emotional or
psychological problems:
1. Decide how students should make up the work: If
teacher decide a student has a legitimate reason to come late, he
can choose to allow it. However, he should decide what the
student’s responsibilities should be vis-à-vis material missed.
2. Use campus resources: If a student who seems to be
experiencing emotional problems that are interfering with his or her
ability to get to class on time (or otherwise function as you would
expect), consult with Counselling and Psychological services or
the Dean of students affairs for advice.
13. Solutions To Root Causes!!!
O There is no consequence to being late:
1. Make your policy on lateness explicit: Articulate policy
about lateness in syllabus and on the first day of class. It will be
easier to respond firmly and authoritatively to lateness if policy is
clear and in writing.
2. Have consequences for lateness: There are a number
of ways to penalize lateness. Some instructors institute a lateness
policy along with their attendance policy.
3. Make the beginning of class meaningful: Make sure there is
a clear benefit for students who are on time by getting started on
time and beginning with important, relevant material. Don’t waste
the first few minutes of class; this only encourages lateness!
