Understanding metering, part one: introduction

Understanding metering, part one: introduction | On education | Scoop.it

One of the more important – yet almost always overlooked – aspects of camera operation is metering. Simply put, the meter determines what your final exposure is, and how bright or dark your image looks relative to the scene. Unless you are shooting manual – and even then – the camera’s exposure is determined by the meter. Add the fact that the eyes of a viewer tend to go to the brightest and/ or highest contrast portions of an image first (i.e. this should be your subject) – and it’s clear to see why it’s absolutely critical to understand both how metering works as a fundamental concept and any camera-specific peccadilloes that might exist. The last thing you want is to find that your camera drastically underexposed a once-in-a-lifetime shot of some critically important event because you didn’t know (or forgot) that the meter was extremely affected by point light sources*.

Uniting Online Learning and Self-Directed Learning – A New Relationship

Uniting Online Learning and Self-Directed Learning – A New Relationship | On education | Scoop.it

The concept of self-directed learning has long fascinated researchers in the field of education for quite some time. Becoming a self-directed learner is found to be most important as we develop into adults. It is often cited as being one of the most important functions of education. However, research has shown that there needs to be a readiness for self-directed learning that comes with maturity.

 

Prior research suggests that in order to be successful in an online learning environment, one must have a technical readiness and a self-directed readiness (Guglielmino & Guglielmino, as cited in Piskurich, 2003). However, with the rapid growth of virtual schooling and states now requiring virtual credits to graduate high school, it is more important that students are successful in an online learning environment.
