Methods to Evaluate Lighting Quality in Educational Environments

A Structured Approach to Evaluate Collaborative Educational Virtual Environments

In this paper we present a 3D collaborative educational virtual environment, which was development by utilizing an iterative applied throughout development cycle. The main propose was demonstrating applicability of an evaluation framework idealized by the authors. Our evaluation framework is supported by the Quantitative Evaluation Framework (QEF) proposed by Escudeiro [3]. This framework uses ...

Discussion- Improving Educational Quality: How Best to Evaluate Our Schools?

While the academic debate has been preoccupied for much of the last decade with school vouchers, state policymakers have been moving in a very different direction, constructing elaborate incentive systems using school-level test-score measures. For instance, California spent nearly $700 million on school-level incentives in 2001, providing bonuses of up to $25,000 per teacher in schools with th...

Discussion- Improving Educational Quality: How Best to Evaluate Our Schools?

Hanushek and Raymond have provided us with an elegant and coherent set of arguments for accountability in the public provision of education. Their main empirical contribution is the characterization of the different types of accountability systems in the United States. They go on to show how the operation of incentives in the public sector is not easy to administer and evaluate. Specifically th...

Lighting Estimation in Indoor Environments from Low-Quality Images

Lighting conditions estimation is a crucial point in many applications. In this paper, we show that combining color images with corresponding depth maps (provided by modern depth sensors) allows to improve estimation of positions and colors of multiple lights in a scene. Since usually such devices provide low-quality images, for many steps of our framework we propose alternatives to classical a...
