Construction and validation of a computer-based diagnostic module on average velocity
1994
This article describes the process of building a computer-based diagnostic module concerning the understanding of the average velocity concept. The first step consists of the production of a student model that takes into account student errors and reasoning paths. The computer module formulates its diagnosis by leading users along different patterns foreseen according to the hypothesized student model. Results are reported concerning a correlation analysis between automatic and human diagnoses.
Conceptual Understanding of Newtonian Mechanics Through Cluster Analysis of FCI Student Answers
2018
The Force Concept Inventory is a multiple-choice test and is one of the most popular and most analyzed concept inventories. It is used to investigate student understanding of Newtonian mechanics. A structured approach to data analysis can transform it in a “diagnostic” instrument that can validate inferences about student thinking. In this paper, we show how cluster analysis methods can be used to investigate patterns of student conceptual understanding and supply useful details about the relationships among student concepts and misconceptions. The answers given to the FCI questionnaire by a sample of freshman engineering have been analyzed. The analysis takes into account the decomposition…
An Indo-French Virtual University Project
2016
Indo-French cooperation has existed for several decades, and has flourished in the recent period, with a number of flagship programmes and cross-border schemes in science, technology and management. Virtual universities refer to both conventional campus-based (hybrid and brick-and-mortar) universities offering online courses, and purely virtual universities with all their activities delivered online via the Internet. A virtual university is involved as a direct provider of learning opportunities and uses the Internet to deliver its programmes and courses while receiving tuition support. We propose in this ultimate chapter an innovative architecture for an Indo-French knowledge management sy…
Structure and performance assessment in traditional face-to-face and blended learning statistics courses
2014
Abstract In recent years the number of higher education institutions offering blended learning courses has increased notably. Blended learning is understood as the combination of traditional face-to-face teaching with online and distance learning. During the 2012- 13 academic year, for the first time, the Information and Documentation degree course at the University of Barcelona included a blended learning format in its course in statistics. The blended learning course combined biweekly face-to-face classes and online work between sessions. This study describes the organization of the blended course in comparison with the traditional face-to- face course and presents preliminary data on stu…
Fault Detection of Networked Control Systems Based on Sliding Mode Observer
2013
Published version of an article in the journal: Mathematical Problems in Engineering. Also availeble from the publisher at: http://dx.doi.org/10.1155/2013/506217 Open Access This paper is concerned with the network-based fault detection problem for a class of nonlinear discrete-time networked control systems with multiple communication delays and bounded disturbances. First, a sliding mode based nonlinear discrete observer is proposed. Then the sufficient conditions of sliding motion asymptotical stability are derived by means of the linear matrix inequality (LMI) approach on a designed surface. Then a discrete-time sliding-mode fault observer is designed that is capable of guaranteeing the…
Frequency stability in microgrid: control strategies and analysis of BESS aging effects
2016
In order to ensure a thorough analysis, all components placed in a microgrid would have to be considered to guarantee an effective energy management. To this aim, various algorithms are used both to preserve and restore power systems after significant disturbances. However, these models frequently do not evaluate components performance decline with the age and, consequently, they don't consider actual values during microgrid analysis, potentially affecting obtained results. In particular, evaluating energy storage systems aging and their effects has rarely been addressed in prior works. The present article proposes a model to maintain power system/microgrid stability after disturbances usin…
Event Reconstruction
2014
Event reconstruction is one of the most important step in digital forensic investigations. It allows investigators to have a clear view of the events that have occurred over time. Event reconstruction is a complex task which requires exploration of a large amount of events due to the pervasiveness of new technologies nowadays. Any evidence produced at the end of the investigative process must also meet the requirements of the courts, such as reproducibility, verifiability, validation, etc. After defining the most important concepts of event reconstruction, a survey of the challenges of this field and solutions proposed so far is given in this chapter. Irish Research Council Science Foundati…
Considering Learners’ Perceptions in Designing Effective 21st Century Learning Environments for Basic Education in Finland
2014
Focusing on so called Key Competences or 21st Century Skills urges educational organizations to redesign their psychosocial and physical learning environments. Inspired by studies indicating that considering learners’ perceptions of learning environments can have a positive impact on learning and wellbeing, our study aims at developing design principles for involving learners in the learning environment design. This pilot case study analyzed 7- to 14-years old Finns’ (n = 80) perceptions by using web questionnaires and design workshops. The results are in line with research indicating that Finnish learners value aspects such as safety and peacefulness, the possibilities for rest and physica…
Introducing Problem Based Learning (PBL) in Textile Engineering Education and Assessing its Influence on Six Sigma Project Implementation
2012
The purpose of this paper is to explore the methodology that has adopted to implement PBL in textile engineering education at “Lucian Blaga” University of Sibiu (LBUS) which also highlights its potential influence on Six Sigma projects that has implemented in a textile manufacturing industry. The function of both PBL and Six Sigma approaches is to solve the problems by executing projects in a systematic way. Structurally, they are quite similar in nature. Many academic institutes around the world are currently introducing PBL to enhance the quality of higher education. On the other hand manufacturing units are trying to shorten their Six Sigma project duration, but interconnection between b…
Product development and project-based learning in Mechatronics, in the context of digitization and sustainability
2021
Engineering projects affect many of the UN’s sustainability goals. The development and design of new products and systems using a circular economy perspective is an important challenge towards a more sustainable society. Product development projects have common process characteristics, but methodologies, tools and methods differ for developing hardware (mechanical and electrical) or developing software. In Mechatronics such methods need to be combined, and product development and project-based learning is well suited for teaching and learning within Mechatronics, in addition to technical specialization subjects within both mechanical, electrical and software engineering. It is also suited f…
