- Dr. Beni: JGSOM
- Dr. Intal
- page 3: Dr. Rodrigo 4th line, “paint jobs”, not “pained jobs”
- page 6: 5.6 – Lani Santos should be Gng. Corazon Lalu Santos

  1. 3, last 2 lines: faculty association; not sure if he had said that.

    Not sure if quoted directly.

Fr. Roche, Babian …?

Curriculum Revisions (MA and PhD psychology): 10 minutes
Dr. Montial

Changing the graduate programs in psychology
- adding a nonthesis track for all the four MA programs
- PhD: changing the social psychology track to social organization

Spirit: want to make the MA level really strongly applied for
professionals who are working and applying knowledge out in the field,
and PhD more for those who want careers in the academe or in research.
Stronger scholarly aspect.

Overview of the changes
Powerpoint slide. Thesis track, non-thesis track.
New:
Developmental psychology
Applied social psychology

Non-theses: Master of Psychology instead of Master of Arts in Psychology

Developmental psychology track reason: focus on child psychology
before, but now more on human development across all stages in life,
including old age. (Don’t worry, you’ll be included here.)

Social and Community Psychology: focus of social psych around 20 to 25
years ago. Now applied social psychology track, will tend to cover
issues tackled by social scientists – peace, environment, women…

PhD in Social Psychology to PhD in Social-Organizational Psychology:
industrial psychology niche

Admission: additions. More industrial experience needed in non-thesis.
Coursework: classroom courses are the same. Main difference -
culminating project. Developmental psychology tracks.

Nature of the non-thesis substitute (culminating project)

Purpose: apply knowledge and do projects that will be useful for
current and future practitioners in their areas of concentration.

Guidelines:

Course changes that will accompany the proposed changes in the programs

Questions:

have to say – individual interviews, focus groups…

be a function of gender. (Placement: we could do that as a followup)

Oooh, teaching story!

July 10, 2003 - Categories: -Uncategorized

My students are brilliant _and_ having fun! =)

I’ve gotten e-mail from students along the lines of “I was thinking in
the shower when…” – they’re thinking about CS outside the classroom,
and they’ve come up with pretty creative ways to do things. Martin
Gomez told me that he was having lunch near their block and he heard
them talking about CS – over lunch! Wow! They were talking about
arrays, poring over source code, animatedly swapping ideas… Some are
even asking how to make programs that make other programs – cool! I
think I can introduce files early as an extra topic. Note to self:
write tutorials over weekend.

Gosh, they’re more advanced than I was when I was in first year, and
enthusiasm’s contagious. =) I’ll do my best to help them reach their
potential while still making sure they don’t overlook any of the
basics. I plan to give them self-review assignments and tests. Yatta!

Instructional needs and learner analysis

- group work: should describe the contributions of each person
- assign students to review two or three programs
- see all the people who have acknowledged your help
- monitor student activity
- peer pressure =)

On Monday, I’ll give a short questionnaire to the students who did not
do well on last Friday’s exam. I want to find out what they’re having
problems with and what kind of help they want.

In this one-day workshop, participants will mine the Web for
teaching and learning resources suitable for the courses they
teach, and design online learning activities that take advantage of
the Internet as an educational tool. A special focus of the workshop
is designing WebQuests. Participants will go through the
instructional design process in order to come up with creative
online learning activities that foster critical thinking and collaborative
learning. The workshop is open to college and university teachers
who are thinking of including online components in a face-to-face
course or transforming a course for full online delivery. Participants
are expected to have basic knowledge in the use of computers and

Looks like I managed to surprise [[bbdb://Jobert][Jobert]]

July 16, 2003 - Categories: -Uncategorized

I used to hang out with their barkada – playing card games, RPGs, that
sort of thing.

In the tradition of blogging, I will proceed to tell a parallel story.
Friday, right? I was off to Eyrie to meet
Dean Michael Berris for dinner. Eric
accompanied me, although I walked a bit ahead. On our way there, Cyril
Tubianosa recognized Eric and asked him where I was. I went back a few
steps, waved hi to Cyril, and found out that Jobert and the others
were in the area for a game. I hadn’t seen them in a while, so we
headed back to Faura and met Jobert and the others. Much standing
around, saying hi, yeah, uh huh – you know me and small talk. After a
few minutes, Eric and I excused ourselves and went to Eyrie to meet
Dean. =)

Jobert’s a pretty okay guy. Not much intersect – maybe RPGs? I wonder if
I should look into (probably someone else’s) PBEM games.

(Nice thing about blogs; I can catch up on people’s lives quickly.)

Looks like I managed to surprise a non-geek, after all. Most people
like my new haircut. I think that Eugene and Bong (well, I
want my students to call me by my first name, so I’m going to have to
learn to do that _sometime_) are of the opinion that I should grow my
hair longer, but this current ‘do is zero-maintenance.

Mail fix

July 23, 2003 - Categories: -Uncategorized

Okay, hmm.

I’m having a hard time figuring out how to properly route my mail. I
have two main mail accounts – my free.net.ph address and my ateneo.edu
address. At home, I can send mail from any account I want, but I have
to use the web interface (IMP) to check my ateneo.edu account for
messages (no POP/IMAP in! pfft). In school, I can poll both accounts,
but I can only send mail from my ateneo.edu account.

I’ve more or less decided to:

- Set my from: and reply-to: to my schua@ateneo.edu address.

- Subscribe my schua@ateneo.edu address to all the mailing lists, but

set my delivery options to nomail.

- Yahoogroups should handle it appropriately.

- Pro: Personal replies tend to get past the mailing list stuff.

- Con: I need to be able to inform everyone when I no longer have an

ateneo.edu account.

Probable solution:

- Use sacha@free.net.ph in my .signature, so that people who run

across my messages will still be able to reach me.

Sounds like a plan!

project-type cooperation
grant aid

donor company will send the experts from universities and private industries technology traansfer, equipment
technical cooperation project
training center in upd
implementation agency is diliman,
results should be diffused to other universities and private it industries including japanese affiliated companies in the philippines
not how to make an effective
how to make an effective project under the jica scheme

training for graduates to general it skill

receive university graduates
training after one year after exam, core and specialist – 12 months (6/6)
not another degree program, but non-degree certification. practical business
one year internship at company

upd has no alumni records

still in design phase
6 or7 months, project will start
in february or march, the technical cooperation with the assistance of japan will commence
one year, make good curricula, subjects, course instruction methods for more practical training
jitse standard curricula
mr. kato is the jitse member
much more practical and broad
jitse standard as much as possible
professors who are accomodating for this kind of different knowhow
concentrate on trainors training
they might go to japan for training
second year, may start a small scale of classes; two classes, twenty five trainees each, two classes in 2005 and then expand to maybe 100 trainees in 2006
grant aid scheme
build a building, provide more equipment, maybe scale up to 200 or 300 or 400 in 2007, not sure yet
whole scneario

basically, aiming to develop people for embedded systems, application development, network
three areas that are high priority from our understanding
microelectronincs, but not sure this could be feasible in this country.
computer aided design
might extend variety to those fields

part time courses saturday, evening for it engineers currently working
special seminars in selected topics – 1 or 2 day seminars in hot issues in IT fields
basic idea

bwhat we are thinking
more cooperative approach among the industries

basic assumption
major instructions for this instructior will be coming from UP, but they should invide faculty of other universities and graduates frim other universities

what do you think

maybe the ateneo join as instructor, or join in courses
expectations from student size and faculty side
lots of different customers

31,000 IT graduates a year

master degree program, at least a master degree holder

another concern: class size 50 or 100 every year, by utilizing existing faculty staff, but when we havea big size, recruit IT instructor, or get help from other faculty members

tokyo institute of technology

asti soft launch of java courses

- part time instructor trained by japanese specialists
- advisory board? mr. rodriguez of up who is the vice president of the whole up, probably some from Ateneo, a team of candidates for future instructors
1000 – 1500 per hour as a lecturer

The Little World of Dan Camillo

Dominique Cimafranca said:

Memory is a very funny thing: all of a sudden it occurred to me to look up
some web references to a series of books I had read a long long time ago.
I don’t even remember what I was doing or thinking about.

Anyway, the series is called “The Little World of Dan Camillo.” It’s
about a priest in a little country village in post-World War II Italy and
his skirmishes with sometimes-friend sometimes-enemy Peppone, the leader
of the local Communist cell. It’s rollicking good fun.

Lo and behold! The complete stories are available on the web! Check out
