PREFACE
In April 2008 the 57-75 Movement organized a workbooks development write-shop in order to come up
with an immediate and effective response to the problem of lacking textbooks and instructional materials in public
schools. For two weeks, master teachers from each of the 57-75 pilot sites compiled a series of workbooks on
Science, English, and Mathematics designed for their elementary and high school students.
The write-shop aimed to: (1) identify least mastered skills in a subject area; (2) produce lesson guides that
will help increase the ability of classroom instructors in developing the mastery level of students particularly in
problematic subject areas; and (3) help teachers be creative in developing their own instructional materials based
on resources available to them in their respective schools.
Both the faculty and students of the public school system are expected to gain from this project. Teachers
will not only be aided by the problem-solving and explanations given in the workbooks but will also be helped in
terms of gearing their students towards a unified understanding of the subject matter. This workbook will also
serve as an alternative medium of instruction in the absence of textbooks and other necessary teaching materials
that the le ss fortunate may not be able to afford.
The workbooks development write-shop is also 57-75’s contribution to enhancing the reading
proficiencies in its pilot sites.
57-75, a private sector-led movement created to help address the many problems of Philippine education,
was inspired by one of the many disturbing indicators of the state of Philippine education – the results of the
National Achievement Test, in which grade school pupils scored close to 57.
The reversal of numbers in the campaign name – from 57 to 75 – symbolizes what the movement is trying
to do: turn things around, about radically rethinking the way we look at our education system and the way we
support it. We believe that this kind of rethinking will help turn around the dismal trends in Philippine education,
and eventually change statistics from 57 to 75.
57-75 advocates Focusing on helping students stay in school, enhancing reading proficiencies, and
improving achievement rates in math, science, and English; student and school Performance; and Community
Empowerment and Engagement.
57-75 wishes to acknowledge the Ateneo Center for Educational Development for supervising the
workshop. Much gratitude is also given to the League of Corporate Foundations’ Committee on Education which
funded the workshop through a grant provided by TeaM Energy Foundation, as well as to Jollibee Foundation for
additional logistical support.
57-75 would also like to especially acknowledge the master teachers from the pilot sites – without their
commitment, this workbook would not have been possible. We also extend our appreciation to the reviewers,
editors and encoders of ACED who accommodated this project into their existing workload.
57-75 is also very grateful to the initial pool of corporate donors who have pledged to help in the
reproduction of this workbook: TeaM Energy Foundation, Petron Foundation, Pilmico Corporation, BPI
Foundation, Metrobank Foundation and Insular Life Foundation. Thank you for helping to reverse the education
crisis!
