Have you ever noticed how training
in calculation helps make
a slow mind quicker?
Plato, The Republic

Remedial Mathematics Education
is a major problem at
U.S. colleges and universities.
The Keystone Method was designed to address the needs
of these students.
04/19/23 Keystone Group-Daley College 4
Keystone Method Hypothesis:
•Unsuccessful students do not lack the intelligence or the desire to succeed.
•Rather, they are held back by behavior patterns, which inhibit learning.
04/19/23 Keystone Group-Daley College 5
Specifically, the Keystone Method recognizes:
1) Students’ short attention spans;
2) Inadequate attention to assigned homework;
3) Short time horizons;
4) Failure to learn from errors;
5) Passivity in class, hoping to pass unnoticed;
6) Poor attendance patterns;
7) Low self-esteem;
8) Ignoring teachers’ statements.

1) To address students’ short attention spans:
•At each class meeting, the instructor gives a time-pressured quiz that requires the students’ full concentration.
•At the beginning of each term, the quizzes are short, no more than 10 minutes.
•Quizzes are gradually lengthened as students’ attention spans increase.
•The quizzes are all cumulative.
04/19/23 Keystone Group-Daley College 7
2) To address students’ inadequate attention to assigned homework:
•The daily quizzes are a reflection of assigned homework.
•Students who regularly complete homework assignments should receive good grades on the quizzes.
04/19/23 Keystone Group-Daley College 8
3) To address students’ short time horizons:
•Students are examined every class period.
04/19/23 Keystone Group-Daley College 9
Research has shown that frequent testing has important educational
benefits for the learner:
•It encourages regular study habits and discourages cramming.
•It mitigates test anxiety.
•Students favor frequent testing over longer tests that carry exorbitant weight.
•It motivates students to constantly review the earlier topics and concepts and helps with consolidation of their learning.
04/19/23 Keystone Group-Daley College 10
4) To address students’ failure to learn from their mistakes:
•Students are provided with immediate feedback.
•Similar questions are repeated in subsequent quizzes until students achieve mastery in the topic.
04/19/23 Keystone Group-Daley College 11
5) To address students’ passivity:
•Students engage in peer tutoring and cooperative group learning.
•Group learning techniques are employed when the standard deviation of test scores exceed 25%.
04/19/23 Keystone Group-Daley College 12
6) To address students’ poor attendance:
•The instructor issues administrative drops for more than three absences, to be reversed only upon the student meeting certain conditions.
04/19/23 Keystone Group-Daley College 13
7) To address students’ low self-esteem, the instructor gives the students:
•Well-defined tasks,
•The tools to carry out those tasks,
•Prompt feedback for their attempts,
•Repeated success when they achieve mastery.
04/19/23 Keystone Group-Daley College 14
8) To address students’ ignoring teachers’ statements:
•The professor gives the students repeated evidence that his/her instructions produces success.

Students in Keystone classes improve in their ability to
focus their attention on a task, even if that task is
not a mathematical one.

Conclusion:
The formative assessment in the form of frequent cumulative multiple-choice quizzes with immediate, constructive feedback reveals the levels of conceptual understanding in a timely manner and improves student academic performance on the summative assessment instruments.
Increased frequency of formative assessment provides better results on the summative assessment.
The results achieved on valid and reliable internal (departmentally designed) summative assessments are an accurate predictor of the scores on external examination (COMPASS Test).

The Keystone Method is the essential piece in an arch: the stone that holds all others in place.
Conclusion:
04/19/23 Keystone Group-Daley College 32
Recommendation:
The Keystone method should continue to be studied, along with other effective methods, to foster student learning in all developmental mathematics classes.
04/19/23 Keystone Group-Daley College 33
What is next?
Powerful computer technologies will simplify the practical use of Keystone and provide:
A. Computerized grading of assignments;B. Automatic item analysis;C. Real-time grading and feedback;D. Automatic assessment of learning
outcomes.
04/19/23 Keystone Group-Daley College 34
What we hope for?
Synergetic combination of the Keystone Method with powerful software technology will further improve students performance.
Computerized Keystone Method will create a possibility for an effective coordination of multiple section classes.
Simplicity and power of this approach will result in wide use of the Keystone Method.
