Embedding e-assessment in an effective way

Fabrication of black printing toner through in situ polymerization: An effective way to increase conversion

Styrene-acrylate copolymer was synthesized in presence of carbon black through heterogeneous polymerization. The percentage of monomer conversion was measured by gravimetric method, also PSA, SEM, DSC and GPC were used for studying the particle size and particle size distribution, morphology, thermal properties and molecular weight, respectively. As well as color properties were characterized b...

Enhancing and Constructing Two Way Matrix Embedding For Efficient Embedding

In designing steganographic schemes, matrix embedding is an efficient method for increasing the embedding efficiency that is defined as an average number of bits embedded via per change on the cover. Matrix embedding is a previously introduced coding method that is used in steganography to improve the embedding efficiency (increase the number of bits embedded per embedding change). Higher embed...

Is formative assessment an effective way to improve learning? A Symposium at Experimental Biology 2008.

Formative assessment is designed to provide information about students' learning to help them and their teachers to identify deficiencies and misconceptions. It differs from summative assessment, which aims to rank students according to their achievements to determine which students pass or fail or to assign grades to students. This article reports on a symposium concerned with evidence for the...

Scaffolding: A way for supporting learners in e-learning environments

Introduction: One of the effective ways to help learners improve their learning in learning environments is scaffolding. Scaffolding can be defined as teachers, other learners and resources support of learner on tasks that can’t be done alone. Experts strongly demand scaffolding to be used to help learners on abstractive and complex issues. The aim of this study is to examine the scaffoldi...
