Interdisciplinary Approach to Teaching ‘Mathematics in the Modern World’

I was a speaker during the Council of Deans and Department Chairs of Colleges of Arts and Sciences (CODDCCAS) Region V General Assembly held from July 17, 2017 to July 18, 2017 at the Mariners’ Polytechnic Colleges in Naga City. I presented a talk about my experiences being a trainer in the Second-Generation GE Faculty Training.

Miss Universe Pageant Philippines

Last April 5, 2017, I passed by the Philippine Postal Corporation in Manila and bought a few items for my “Philippine stamps about Philippine stamps” collection.

To celebrate the holding of the 2017 Miss Universe Pageant in the Philippines, three stamps (with denominations of 12, 17, and 55 pesos) and one souvenir sheet (with a denomination of 100 pesos) were issued on January 24, 2017. 103,500 of the stamps and 6,000 of the souvenir sheet were made.

I was able to buy a miniature sheet (with the designs in a se-tenant strip of three) (for 252 pesos), a souvenir sheet (for 100 pesos) and the first day covers (for 99 pesos and 115 pesos).

There were no ready-made first day covers for the three stamps, so the employee at the store sold me the stamps and the first day cover separately and told me to go upstairs to have them postmarked. From the stamps available for sale, I chose three with a bottom selvage. (I’m hoping mine is the only first day cover with selvage.)

70th Anniversary of the First Stamps of the Republic of the Philippines

Last April 5, 2017, I passed by the Philippine Postal Corporation in Manila and bought a few items for my “Philippine stamps about Philippine stamps” collection.

To celebrate the 2016 National Stamp Collecting Month, three stamps (each with a denomination of 12 pesos, with the designs in a se-tenant strip of three) and one souvenir sheet (with a denomination of 55 pesos) were issued on October 21, 2016. 81,000 of the stamps and 5,000 of the souvenir sheet were made.

I wasn’t able to buy any of the three stamps, but I was able to buy the souvenir sheet (for 55 pesos) and the first day covers (for 44.96 pesos and 63.96 pesos).

Second-generation training

(This post is an English translation of this one.)

I am a trainer in the “Second-Generation GE Faculty Training” described in Commission on Higher Education (CHED) Memorandum Order (CMO) number 8 series of 2017 titled “Implementing Guidelines for the Faculty Training for the New General Education Core Courses: Second-Generation Training.”

Ateneo de Naga University (ADNU) is a Delivering Higher Education Institution for this training. (See this letter from the CHED Office of Programs and Standards Development and this Memorandum from the Chairperson for Region V.) I am a trainer for the course “Matematika sa Makabagong Daigdig” (Mathematics in the Modern World). The training will be held in ADNU from April 24, 2017 to May 13, 2017.

The Philippines in 1598

Swann Galleries sold this double-page engraved map of the islands of Southeast Asia last December 8, 2016. Lot 70 was a copy of Petrus Placius’s Insulae Moluccae Celeberrimae printed in 1598. What interested me the most is the fact that the Philippines is represented with Luzon and Visayas in blue and Mindanao in red, implying that Mindanao is a separate entity from the rest of the Philippines.
