2017 ACM-ICPC Philippines Southern Luzon

I was a problem setter and judge for the 2017 ACM-ICPC Philippines Southern Luzon Invitational Programming Contest held last October 1, 2017 at the Ateneo de Naga University. Seven teams from five schools joined, which is much less than the numbers in the previous years (15 teams from 9 schools in 2016, 13 from 6 in 2015, 31 from 13 in 2014, 32 from 15 in 2013). The contest problems and solutions are here. I provided two contest problems: “C” (Sharkovski Successor) and “D” (String Substitution). I was also a problem setter and judge in 2016, 2015, 2014, and 2013.

20th PMO: Instructions for Qualifying Stage (Region 5)

The 20th Philippine Mathematical Olympiad Qualifying Stage will be held on the afternoon of Saturday, October 28, 2017.  It is a written exam consisting of fifteen multiple-choice questions worth 2 points each, ten multiple-choice questions worth 3 points each, and five answers-only questions worth 6 points each.

The Regional Testing Center for Region V is Ateneo de Naga University. The qualifying stage will be held at the first two floors of the Pedro Arrupe, S.J. Hall of the ADNU Bagumbayan Campus (Ateneo Avenue, Bagumbayan Sur, Naga City); registration will be done in the same building.  The participants must be in their assigned examination rooms by 1:00 pm.  The exam starts at 2:00 pm and ends at 5:00 pm (even for those who arrived late).

Participants must be at the venue before 12:00 nn to register.  The registration fee of PhP 150 per participant must be paid before the exam starts. An official receipt will be given for each school (and not for each participant).  Applicants who submitted their application forms through e-mail must submit the original application forms to the registration staff during registration. Participants and coaches must bring identification cards that have ID pictures, preferably those issued by their schools.

Scratch papers will be provided during the exam.  The only materials that the participants are allowed to have on their desks immediately before the examination are:  blue or black ballpoint pen, pencil (required), eraser, ruler, compass, and protractor.  All other items such as notes, books, cellular phones, etc. are not allowed on the participants’ desks, but these may be placed in a designated area in the room.  Calculators are not allowed.

Participants are not allowed to leave the examination room during the exam. (Participants who need to use the bathroom must do so before the exam starts.) Participants who leave the room before the exam has ended are considered to have finished the exam; they must submit their questionnaires and answer sheets to the proctor before they leave and they are not allowed to return to continue the exam.

Certificates of appreciation for each student and each coach and certificates of appearance (only for those who explicitly request it) will be distributed to the coaches or school representatives.

Conference and Enrichment Sessions on the New GEC

Last September 2-3, 2017, the Council of Deans and Department Chairpersons of Colleges of Arts and Sciences (CODDCCAS) Region V held a Conference and Enrichment Sessions on the New General Education Curriculum at the Ateneo de Naga University in Naga City. According to the Commission on Higher Education Regional Office V CHED Regional Memorandum number 82 series of 2017, the activity aims to “enrich approaches in teaching the new GE courses that the General Education teachers will be handling this SY 2018-2019.”

I and Marivic Fullante handled the sessions on “Mathematics in the Modern World.” (I lectured during the morning of September 3, 2017, and she lectured during the afternoon.) Here are the slides that I used: Introduction, Mathematics in Our World, Mathematical Language and Symbols, Problem Solving and Reasoning, and Geometric Designs.

I also talked about the teaching of mathematics using the Filipino language.
