The problem solving competency is the primary goal in all mathematics education curricula. It is acquired by solving mathematical problems belonging either to routine or non-routine category. The study describes the post-secondary students' levels of proficiency in solving non-routine math problems. The three-stage process in solving mathematics problems by Mayer was used as the frame of analysis. Using the data generated from researcher made instruments, and semi-structured interview of 50 purposively selected participants, the study found that: Majority of the participants showed "good proficiency" in "problem representation" and "problem solving", the real world problems in Math. It is also revealed that those who are good in problem representation phase are also good in problem solution phase. In general, participants do not always consider answer verification phase as important in the process of solving real world problems in math. The most common difficulties encountered by participants are: language inadequacy and unfamiliarity with the context of the problems. The researchers recommended that the same study be done in some other context and local and if the results are consistent with this study, may consider redesigning new curriculum in post-secondary mathematics education.

The purpose of this study entitled Arduino-based Control and Monitoring System of Household Appliances status using Android Application is to help the people to have control over the house by means of switching on/off and monitor the loads that are plugged into the outlet by the use of cellphones/ tablets. This project provides the simple way to access loads that are left running and forgotten to unplug at home. The structure of the prototype is made up of HardieFlex physical appearance making it fire retardant consisting of 3 sockets available. The 2 outlets are for the normal house sockets while the other one is separated for the Air-condition unit. The circuit breaker is on the upper left side corner dividing the wires of each sockets. The Android Application uses text messages to send information then received by the GSM (Global System for Mobile) and translates it to the Arduino. The Arduino commands the relays to cut and provide electricity for the outlets. This device can notify an individual if there are loads left running, wherein the current sensor able to read the current from the outlet to determine if it has a working load that are plugged into the outlet. The study implements power interruption notification in terms of using the voltage sensor to acquire information of possible power outage occurrences. Based on the results of the evaluation, 95.83% believe that the project was made conveniently, that they are now aware of their surroundings giving them the idea of their house is beyond their reach, and also 95.83% of the respondents are certain that the system is relevant and beneficial to the society.
