TSW differentiate the kinds of procedures from notes, participate in a
discussion, read & organize a diagram of procedures and work in a cooperative
group to prepare a poster about imaging & choose types of contrast medium.
TTW use notes, examples, discussion, technology (websites), and role-plays
to demonstrate material.

VII. Assessments
A. Lesson 1 – Students will be assessed on participation, worksheet completion,
correct responses to questions, & the group activity- correctly placing Barbie
in position for x-rays . This will be a 100 point daily grade.
B. Lesson 2- Performance indicator for this lesson would be completion of vocab.
assignment and correct responses on the 4 x-ray pathways.
C. Lesson 3- Four groups will create a poster with diagnostic tests classified into
Invasive or non-invasive categories. A grade will be taken for the group work.
D. Lesson 4- A 50 point quiz grade will be given today for a skill test on properly
aligning / positioning the patient for a radiology test & role plays.
E. Lesson 5 – Student’s responses to questions about how MRI’s & CAT scans
work will show their understanding. Four case studies with problem solving
type scenarios will be graded. By now, I can tell if a learner is progressing along
with the terminology & skills needed for successful completion of this Unit.
F. Lesson 6- This is the most fun assessment of the Unit. The m & m activity
demonstrates half-life in a way they can visually see and appreciate. They
complete a graph showing their results and get a grade for this.
G. Lesson 7- By this time in the Unit they are ready for a short quiz (matching) on
diagnostic tests. A test grade is given and the therapeutic radiology lesson is
assessed on participation in the discussion & internet research.
H. Lesson 8- A notebook grade is taken this week for organization & having notes.
I. Lesson 9 – (Review) A daily grade is given for answering questions and
participation. Score is kept for the teams and the winners get either candy or
bonus points. The Unit Test is a 100 point test.
J. Field Trip- Students are given a daily grade based on behavior and a
summary of their favorite area at BCHS. A report on a career in this cluster
will be graded as a project (weighted heavier than a test grade).

IX. Reteaching
In the case where Reteaching is necessary, I prefer to use methods where the student
is active in participation of a game such as Jeopardy, Bingo, word search, crossword
puzzles, practicing hands-on performance skills or listening to a guest speaker in
that profession. Much of this class is skills, terminology, and concepts new to the
learner, so many times we need to reteach the material. Repetition using visual aids
(videos or microscope slides), computer activities (CD Rom games ) & group poster
projects are effective tools for my class, since I have so many visual learners. I also
use many team or group activities. The students must understand they will be part
of a Health Care Team for patient management, and they must be a willing learning
partner.
EnrichmentTwo of my students benefit from some type of enrichment. I have many reference
books, computer aids (such as “Cardiac Arrest”, “Heart & Lung Sounds”, “Medical
Terminology Challenge”) and Current Events in Health Care to offer added material
and challenges to these students. I use the students to help me in demonstrations and
hands-on skills where other students need help. Many times there are questions about
diagnostic medical procedures or medications that these students can research &
report on to the class ,by using the computer or in Mosby’s or Taber’s Medical
Dictionaries.
ModificationsTwo of my students need mild modifications. One is handicapped and has some
physical & mental limitations and the other is an ESL student. Both are very
interested in Health Care Careers and work hard to succeed. Some modification is
needed on critical thinking/problem solving scenarios (higher order skills) and some
on terminology. These students are well received in the class and get help from
other students as well as modified assignments.
