Project DIAPLASIS (Greek Acronym for “Online Platform for School – Family Collaboration”) is a Doctoral Thesis aiming to develop an online system that allows collaboration between school and family, and to evaluate possible learning results in a two-year intervention with at-risk students. At least 9% of students in Cyprus are found to be at risk of failure in Language and Mathematics. Research...
This paper describes the process used to develop and implement an assessment plan from the ground up for a new Master of Information Systems program. The mapping of learning goals to objectives to specific courses is illustrated with direct and indirect measures. The program was first offered January 2008, and the second cohort of completed January, 2010. Assessment results from the first two c...
Voltage sensing technology is crucial in realizing distributed voltage at critical nodes of the power grid and providing key state variables to provide information support for control decisions. Among existing measurement methods, transformers have problems such as high insulation performance requirements limited installation locations. However, non-contact sensors designed based on electric fi...
− The paper presents a stochastic sampling method applied to a measurement of the mean value of the product of two arbitrary signals. This method is especially convenient for measuring electric power, electric energy consumption, as well as root-mean-square of voltage and/or current. The method features a very simple hardware and the possibility of selecting the measurement accuracy by choosing...
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
while performance-based language assessment has led to an increased authenticity and content validity in the practice of writing assessment, the reliability of ratings has become a major issue. research findings have shown different reactions by native english speaker (nes) and non-native english speaker (nns) teachers to students’ writings. the focus of this study is on investigating whether i...
We propose a modular approach to development of a computerized adaptive practice system for learning of facts in areas with widely varying prior knowledge: decomposing the system into estimation of prior knowledge, estimation of current knowledge, and selection of questions. We describe specific realization of the system for geography learning and use data from the developed system for evaluati...
learning-oriented assessment seeks to emphasise that a fundamental purpose of assessment should be to promote learning. it mirrors formative assessment and assessment for learning processes. it can be defined as actions undertaken by teachers and / or students, which provide feedback for the improvement of teaching and learning. it also contrasts with equally important measurement-focused appro...
introduction: arterial stiffness is an important predictor of cardiovascular risk. several indices have been introduced to estimate the arterial stiffness based on the changes in the brachial blood pressure. since the substitution of the blood pressure changes in the central arteries such as carotid with the blood pressure changes in the brachial results in error in the blood...
