The technology works as a catalyst through which many changes occur in the learning approaches, teaching methodologies, research arena, in the work environment and in the use of information and knowledge. Helping students to learn using technological tools rather than using conventional techniques has become more popular in the 21st century in colleges and schools in the domain of computer science. Integration of technological tools will help teachers to the international requirement to use technology-based teaching and learning tools instead of traditional teaching methods. Most researchers agree on the significance of the use of technological tools in different education systems. However, current state-of-the-art depicts that there is no comprehensive study that provides an analysis of different technological tools e.g. computer-based, games based, mobile based, and multimedia technologies used in education. This paper provides a comprehensive review of several of the most popular teaching methodologies (collaborative, active learning, problem-based, inductive teaching method) and technological tools i.e. computer-based (ICT, CAI, CBI), games based (serious games, web games, micro-games, videos games), mobile based (laptop, PDAs, tablets, mobile phones), online learning tools (flipped classroom, web MOOCs) and multimedia technologies (Videos, MCMs, MAMCM). The purpose of this research paper is to scrutinize the roles and effectiveness of technological tools in teaching and learning process and it provides the definition of each method, along with the similarities and differences among these teaching methodologies and technological tools. Even though the strength of each individual method is something that is met with varying degrees of evidence, teaching with the help of technological tools has been found to be generally more effective or at least equally effective to traditional methods of teaching. The purpose of the use of technology in teaching and learning process is to improve productivity, the effectiveness of current practices and bring pedagogical changes which are beneficial for the betterment of education. We explore the theoretical literature available about the influence of technology and its effectiveness in the field of education. In teaching and learning process, the use of technological tools increases interaction between teachers and students. To incorporate technology, educators and teachers must implement the right technological tools to make the environment more innovative for the students.

A Review of Technological Tools in Teaching and Learning Computer Science

In this work, new analytical method‐based computer‐aided manufacturing (CAM) software tool developed for educational purposes is introduced. The software has been conceived for the designing, analysis, and optimization of the multi‐step wiredrawing industrial process. The software was used during four sessions and the student's feedback has been measured by a usability/suitability survey. This paper presents the complete study of the previous situation in the Area of Manufacturing Processes in the Superior Polytechnic School (University of Cordoba, Spain). The positive results from the students encouraged us for the integration of new practical activities supported in the use of this type of software tools, to reinforce the professional skills of students, and show that the new CAM software presents a great potential for competency‐based learning objectives.

Advanced cad capabilities applied for integrating flexible engineering design with flexible manufacturing

This research aims to complement and enhance the understanding of friction and wear behavior of AA7075 and CuZn39Pb2 under different conditions. One set of experiments were conducted under the laboratory conditions, simulating an ideal case using a ball-on-disc configuration, while the other set of experiments were conducted under the actual field conditions using a pin-on-disc configuration on a newly developed wear test bench. Effect of various tribological parameters such as load, sliding speed and wear track diameter was evaluated on the contact surface temperature, wear loss, wear rate and coefficient of friction. SEM analysis of worn surfaces and the wear track for each alloy were analyzed and compared. Results showed that different surfaces respond differently according to the type of wear test, the nature of material and the operating conditions. Even though, the error deviation in the wear rate calculations under both laboratory and actual field conditions does not exceed 10.75%, the results showed that the actual field conditions cannot be extrapolated from the ideal laboratory operating conditions. However, a comparative case study between an industrial setup and a lab setup shall definitely help in developing a better understanding of the wear behavior of materials by linking field conditions with that of the conditions in a laboratory. Moreover, results from an industrial setup can contribute to providing prototypes for solving industrial problems.

Optimisation of the machining time required by insole orthotic shoes for patients with clubfoot using the Taguchi and response surface methodology approach

The advantage of the technological assisted design consists in easy modification of the machining technologies for obtaining machine alternation, tool changing, working parameters variation or the modification of loads to which the tools are subjected. By determining tool movement inside machining and by using tool related moving speeds needed for both positioning and manufacturing we are able to compute the required machining time for each component of the machining operation in progress. The present study describes a cost optimization model for machining operations which uses the following components: machine and its operator related cost, set-up and adjustment, unproductive costs (idle state), direct and indirect costs. By using manufacturing technologies assisted design procedures we may obtain various variants for the technological model by modifying the machining strategy, tooling, working regimes or the machine-tool that are used. Simulating those variants allows us to compare and establish the optimal manufacturing variant as well as the most productive one.

Increase Productivity and Cost Optimization in CNC Manufacturing

E-learning methods apply to most modern and various domains but also represent a great tool for the mechanical educational system where there are a lot of sustained efforts for its implementation. Using, administrating and maintaining an e-learning system for a certain field of study requires knowledge related to computation system's utilization but also the understanding the working mechanisms behind it that allows the system to be fully customized in order to be perfect fitted to the user's needs and requirements. A Moodle based test is evaluated from several points of views such as coherence clarity, concise content, information synthesis capacity and the presentation mode which makes the difference between clear or fuzzy graphical representations or terms. The authors appreciate that the ability of managing information in real time by the professor is a decisive decision in order to successfully implement an e-learning web platform. Updating information and structuring trainee's activities from thoroughgoing study up to their individual proposals for conceived applications leads to a better understanding and practical knowledge of theory.

E-learning implementation in superior technical educational system

Elastic deformations of the technological system occur during the mechanical treatment of a blank, regardless of the manner in which it is fastened. The elastic deformation of the blank is significant especially when machining shaft-like parts. The purpose of our research is to compare the mathematical model of blank deformation to the experimental model when the blank, which is a part belonging to the shaft class, is fastened between centers.

A lot of specialists, both academia and industrials, agree that nowadays Romanian manufacturing industry is forced to unprecedented transformations, determined by the complex present conditions of European integration. Of course, trends like globalization and products complexity growing, in the sense of their variety, have important impacts upon production and upon all its support functions. Productive companies such as machine manufacturing enterprises usually have to manage a great number of variants in their product portfolios and they also must be agile and achieve short delivery times, as long as most of the customers ask for specific, individually developed solutions, within a fast changing market environment. The present paper comes to emphasize a vision upon PLM as a strategic instrument for concurrent engineering and for sustainable product design, basing on the results of a research experiment of implementing a PLM solution within a network composed of technical universities, research institutes and productive enterprises. In this context, PLM is outstood as a sustaining pillar for the discrete manufacturing in the productive company, entirely able to help in solving the above mentioned problems, no matter that there still exists considerable confusion among the specialists from enterprises as IT users, concerning the usefulness of the related software applications. On the other hand, there is presented in the paper that the concept of Sustainable Product Design must be considered in relation with Life Cycle Analysis (LCA) and with the Extended Producer Responsibility (EPR). The concepts of Reducing, Reusing, Recycling and Recovery of material resources are also nominated as being very important in providing Sustainable Product Design.

A vision upon plm as strategic instrument for concurrent engineering and for sustainable product design

Electronic learning, distant learning, collaborative work, mobile learning and internet based learning concepts are ever more present in superior learning systems. At this date for study or for finding different information we may access different search engines (like Google) where we can consult information based websites, blogs or online tutorials. Elearning systems can be grouped in online systems that have no direct interaction between the students and the professor, face to face systems that use both electronic resources and student-professor interaction, selflearning systems based on blogs, tutorials, teaching programs or web based systems. We can safely assume that e-learning is rapidly growing and that many universities have online free platforms developed for aiding students. The technological leap of current industries poses new challenges for the traditional educational systems. Efforts are known and acknowledged for changing and enhancing the existent educational systems and the orientation towards online learning processes.
