1. Writing a Problem Statement
TOPIC: the use of graphing calculators in teaching algebra
As a question: How are graphing calculators
used in teaching grade nine algebra?
As a hypothesis: The achievement of grade nine
students taught algebra with graphing calculators
will equal or exceed that of grade nine students
taught without graphing calculators.
As a null hypothesis: There are no differences in
achievement in algebra for grade nine students
taught with graphing calculators as compared to
those taught with out graphing calculators.

3. Is this research?
Consider these examples

4. During an informal discussion with a group
of students, Ms. Chan heard someone say,
“Teachers always ask the same people to
answer the hard questions.” She began to
wonder if that were really true. To find out
she sat in the back of another teacher’s
class and wrote down each question asked
and the student to whom the question was
directed.

5. Mr. Ramirez was a beginning nurse. He kept
hearing about Ms. Blaine who was “the best
nurse in the clinic.” In order to find out what
Ms. Blaine did that earned her that
reputation, Mr. Ramirez arranged to shadow
her at work three times each week. He also
talked to patients and other staff about their
reasons for thinking Ms. Blaine was a good
nurse.

6. Mr. Gordon was interested in the ways
school counsellors thought students learned
about career options. He developed some
tasks that he thought would help
counsellors to talk about their ideas about
student career choices and used the tasks to
interview some colleagues.

7. Ms. Berliner had just received a new computer for
her classroom. She was curious to find out if
students would learn multiplication facts better
using the computer instead of regular workbook
assignments and class drills. To find out, she
arranged for every other student in her class to use
software designed to teach multiplication, while the
other students used the workbook and participated
in class drills. She gave all the students a pretest and
a posttest to see if the computer group differed
from the regular group. She presented the findings
to the local math teacher association.

8. Many kinds of research
LOGICAL (mathematics, philosophy)
EVALUATION (judging, appraising)
INVESTIGATIVE (law, government hearings, journalism)
DEMOGRAPHIC (economics, census, polling)
MODUS OPERANDI (forensics, medical diagnosis)
EMPIRICAL/SCIENTIFIC (social science, education, physical science)
