Capacity building for lesson study implementation in grade 3 and grade 7 mathematics

Last July 5, 2018 to July 7, 2018, I was a participant of the activity “Capacity Building for Lesson Study Implementation in Grade 3 and Grade 7 Mathematics” conducted by the Department of Education, Naga City Division at the Villa Caceres Hotel in Naga City. More detailed information can be found in the images below.

Additional information about the program can be found in Division Memorandum no. 165, s. 2018.

I and Glenda Quinto were the Lesson Study Team Resource Persons from Ateneo de Naga University. The picture below shows us with the resource speakers Levi Elipane and Bill Atweh.

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.

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.

May bago akong blog

Right now I’m a participant in a training sponsored by the Commission on Higher Education (CHED) and given by the Ateneo de Manila University (ADMU). I’m being trained to possibly train other teachers how to teach a new general education college course called “Matematika sa Makabagong Daigdig” (Mathematics in the Modern World) to be offered starting 2018. One of our problems is that there are practically no existing materials (articles, textbooks) written in Filipino about college-level mathematics. To try to address this problem, I’ve decided to create another blog that focuses on this new course. The URL is https://matematikasmd.wordpress.com/ . I hope to provide information and resources that will be of help to teachers and students of this course. (Note that it is a personal blog, and is in no way affiliated with CHED, ADMU, or any other institution.)

PERJ Call for Articles for 2016-2017

(This announcement is taken from http://www.fape.org.ph/.)

The Private Education Assistance Committee (PEAC) invites researchers to submit papers for the upcoming issue of the Philippine Education Research Journal (PERJ), the official research publication of the PEAC.

PERJ is an online, open access journal that is published twice a year. It serves as a platform for the dissemination of research that focuses on Philippine education and of interest to decision-makers, policy-makers, and educational leaders and practitioners in the country.

PERJ is seeking previously unpublished articles of original research. Interested researchers should read the PERJ Editorial Policies and Procedures, Author Guidelines, and Review Guidelines.

Those interested should email their article to denise.adriano@fape.org.ph and indicate “PERJ 2016-2017 Submission” as subject. The PEAC National Secretariat will accept article submissions until April 30, 2016.

For inquiries, please call the Communications and Research Unit at (02) 845-0169 local 150 or 162.

2016 Bicol Mathematics Conference

The 2016 Bicol Mathematics Conference will be held on February 29 to March 2, 2016 (Monday to Wednesday) in Ateneo de Naga University, Naga City, Philippines. Three plenary talks will be given (pure mathematics, applied mathematics, mathematics education). I am the plenary speaker for mathematics education.

Theory of Quantity

During the recent EARCOME 7 conference, one of the exhibitors was a group of Japanese who showed participants how to create a lot of concrete learning materials (manipulatives) such as origami sculptures. I assume that they are members of The Association of Mathematical Instruction (AMI) because they gave me a complimentary copy of AMI’s Principles of Mathematics Education.

EARCOME 7

I recently presented a poster and a paper at the 7th ICMI-East Asia Regional Conference on Mathematics Education (EARCOME 7) last May 11-15, 2015 at the Waterfront Cebu City Hotel.

The poster and the paper were based on parts of my dissertation with Dr. Vistro-Yu as my advisor. The poster had the title “Assessing Proportional Reasoning Skills and Understanding Using the Water Rectangle Task” and was co-authored with Dr. Vistro-Yu. (A copy of the poster is here. The poster is the one on top in the photograph above.)

The paper had the title “Teaching Proportional Reasoning Concepts and Procedures Using Repetition with Variation” and was co-authored with Dr. Vistro-Yu. (A copy of the slides is here. Also shown in the photograph above is the session chair Enriqueta Reston.)

Order of operations

48d4t12
It is generally accepted by mathematics educators and by scientific calculator companies that in the “correct” order of arithmetic operations, multiplication and division are done from left to right. Thus, 48÷4×12 is evaluated as 144. The Casio fx-82MS and the Casio fx-350ES shown above give this answer. There is, however, some disagreement whenever parentheses are used to indicate multiplication.

My daughter’s high school teacher asked her to evaluate 48÷4(12). My daughter’s answer was 144; her teacher’s answer was 1. What answer is given by the calculators?
