Economics can be defined as the study of consumption and production of goods and services. There are factors of production such as labor, labor and capital that are needed for any economic system to function. Choices are made due to limited amount of resources. Economic efficiency is a based on making optimal use of scarce resources in order to maximize benefits. In the market system, there are many ways to determine efficiency. Two economic concepts regarding efficiency are allocative and productive efficiency.

Allocative efficiency is based on whether goods and services produced matches changing needs and preferences that we place with the greatest value. Allocative efficiency can be achieved when no one is better off without making someone worse off; this is also known as pareto efficiency. Allocative efficiency is the point of the productive frontier where you cannot produce one more good without giving up another. In achieving allocative efficiency marginal cost is equals to price. On the other hand, productive efficiency can be defined as a concept of producing goods and services at the lowest cost. This is the outcome achieved at all points on the productive possibility frontier. In this case, only one more product can be produced at the expense of producing less of another product. Product efficiency requires firms to use the best technology in order to push the productive possibility frontier outward and for business to produce more output.

The Arab Regional Agenda for Improving Education Quality (ARAIEQ) is a program designed to improve the quality of Middle East and North Africa schools. The purpose of this program is to improve the education systems of these regions. Just like many undeveloped countries, Arab countries know the importance of a quality education system on their future. Thus, at the ARAIEQ meeting, was held in Tunis, leaders discussed and proposed probable solutions for improving education in the region.

This source from the World Bank presents some of the discussed topics at the ARAIEQ meeting. One of the major talking points is creating measurably better systems. In essence, governments should make data on the quality education systems public. This is objective of ARAIEQ’s evaluation program. Another idea is schools buildings and ICT. Technology today has become an important part of education. Many developed countries have are using technology to teach students as it inspires students to learn and be creative.

Hui Soo and I are going to attend a talk by Yoav Bergner ( from ETS.

Here is the abstract:
The ability to automatically distinguish between successful and deleterious patterns in collaborative learning sessions opens doors to improved opportunity for learning in pairs or groups even when a teacher might not be available to facilitate. In this
presentation, data from one-time computer-based peer tutoring sessions are modeled using hidden Markov models (HMMs) in two ways. The first model uses an input-output HMM to compare the assistance value of different tutor inputs in helping the tutee correct a mistaken step in solution. This model uses only automatically generated codes based on context and cognitive content of the tutor chat. It’s successes and failures are both informative! The second model predicts tutee normalized gains from pre- to post-test in the experimental condition. Both cognitive and affective labels to tutor chats (human-coded) were included as well as tutee (in)correctness, undos, and chats back to the tutor. Performance of the HMM is favorable compared to a static logistic regression model using aggregated totals of the same observables. Some of the hidden states are readily interpretable, though deeper comparison between high- and low-gain groups is part of ongoing work.

Entrepreneurs from Africa have founded Funda, an e-learning platform. They have partnered with various universities across the continent to provide online courses for their students. They provide content development services to partner institutions and the course offerings are usually at a cheap price. Due to lack of electricity and technological resources in other parts of Africa, most of the work is with institutions in South Africa. Funda’s long-term goal is to be the top e-course provider in Africa. They also believe e-learning’s convenience and capability to match anyone’s schedule will improve education in Africa when access to technology becomes readily available for the majority.

Just thought I would share this round-up of leading video marketing trends. (Note the in-article promotion of Wideo - subtly brilliant)

Here is my brief summary:

  • Be responsive to current events
  • Mobile is here to stay
  • "There are over 1 billion active Facebook users, and 25% of them have shared a video onto a social network."
  • Relationship BUILDING is key
  • Video promotions are far more effective than email alone
  • Be upbeat and casual in your communication style

Teacher Reform in Indonesia

InIn an effort to improve education quality, Indonesia’s government implemented the Teacher Law in 2005. The law required every teacher to earn a four year-degree as well as certification. In the Vialogue below, one teacher shares her experience about the difficulties she encountered prior to obtaining her degree. Additionally, she discusses the accomplishments a four year-degree has brought to her teaching life. Tina Setiawati claims she was not confident in teaching because she didn’t know any good teaching methods. After obtaining her degree, she now teaches with confidence, which in turn motivates her students. I believe this is a great example for many developing countries to emulate. After all, teachers are the agents for students to do well. Thus, if there are better teachers in every classroom, students will do well and learn.

The Maker Faire 2014 is about to happen this weekend at the New York Hall of Science. If you have not heard about it, it is the largest event that brings together the maker community, DIYers, geeks, hackers, cosplayers, sci-fi fictionists and more. They come as a team and individuals to show what they can make from sound installations, interactive art pieces, experimental electronics, internet of things to rube goldberg machines – CRAZY.

As part of the MFA Design and Tech grads from Parsons, I'm exhibiting my interactive sculpture piece "DATA RUSH" at the Parsons booth.This should be a good event so come see and meet with the geeks, be inspired or just have fun! I also have five discounted tickets to share if you're interested.
