Comparison of tradition and ADRI based teaching approaches in an introductory programming course

Aim/Purpose: This study introduced a new teaching and learning approach based on an ADRI (Approach, Deployment, Result, Improvement) model in an introductory pro-gramming (IP) course. The effectiveness of the new teaching and learning pro-cess was determined by collecting feedback from the IP instructors and by analyzing the final exam grades of the course.Background: Learning to program is considered a difficult and challenging task for a consid-erable number of novice programmers. As a result, high failure and dropout rates are often reported in IP courses. Different studies have been conducted to investigate the issue. One of the reasons for this challenge is the multiple skills that students have to master in order to be able to build programs. These skills include programming knowledge and problem-solving strategies and being able to pay equal attention to these required skills in the IP course.Methodology: A focus group was conducted to obtain feedback from the IP instructors about the ADRI approach. The performance of the students who had completed the IP course before ADRI was compared with those who used the ADRI ap-proach by undertaking a comparative analysis of their final exam grades.Contribution: The study demonstrates that the new teaching and learning approach based on the ADRI model encourages students to pay equal attention to programming knowledge and problem-solving strategies, discouraging programming shortcuts and reducing high attrition rates (failure and dropout) in the IP course.Findings: The results of the focus group show that the instructors preferred the ADRI approach compared to the traditional approach. The final exam grades show that the students performed better in semesters which offered the ADRI ap-proach as compared to those semesters without this approach.Future Research: Future research will explore the ADRI approach in other fields of computer science studies, such as database and data structure, to determine if its impact has a wider application than just teaching introductory programming

Impact of Assurance of Learning (AOL) in programming course for novices

One of the aims of any higher education institution is to align its curriculum with program learning goals. Programs which ensure proper learning have positive effects on students, instructors, departments and also on the higher education institution itself. This paper discusses the implementation and effects of Assurance Of Learning (AOL) processes on introductory programming (IP) courses. It elaborates five stages of AOL to align program learning goals with IP curriculum. Then, it discusses how the AOL process identifies shortcomings in the assessment methods of IP courses. Furthermore, it enlightens how the assessment findings, as a result of the AOL process, provide mechanisms to address the drawbacks during the delivery of such courses. Feedback o

Recent advances in the role of rehabilitative therapies for Parkinson’s disease: A literature review

Regardless of medical therapies and surgical interventions for Parkinson’s disease, patients develop progressive disability. The role of therapies is to maximize functional ability and minimize secondary complications through movement rehabilitation within a context of education and support for the whole person. The overall aim is to optimize independence, safety and wellbeing, thereby enhancing quality of life. Trials have shown that physiotherapy has short-term benefits in Parkinson’s disease. However, which physiotherapy intervention are most effective remains unclear. This article provides a guidance framework rather than a ’recipe’ for treatment. This review shows that a wide range of rehabilitative therapy interventions to treat Parkinson’s disease have been tested. There is a need for more specific trials with improved treatment strategies to underpin the most appropriate choice of therapy intervention and the outcomes measured. According to research in the literature, this review is of particular importance because it discusses many rehabilitation therapies for patients with Parkinson\u27s disease in a single paper, for the first time. The aim of this review article is to evaluate the effectiveness of one therapy intervention compared with a second approach in patients with Parkinson’s disease

SecureSurgiNET:a framework for ensuring security in telesurgery

The notion of surgical robotics is actively being extended to enable telesurgery, where both the surgeon and patient are remotely located and connected via a public network, which leads to many security risks. Being a safety-critical application, it is highly important to make telesurgery robust and secure against active and passive attacks. In this article, we propose the first complete framework, called SecureSurgiNET, for ensuring security in telesurgery environments. SecureSurgiNET is primarily based on a set of well-established protocols to provide a fool-proof telesurgical robotic system. For increasing the efficiency of secured telesurgery environments, the idea of a telesurgical authority is introduced that ensures the integrity, identity management, authentication policy implementation, and postoperative data security. An analysis is provided describing the security and throughput of Advanced Encryption Standard during the intraoperative phase of SecureSurgiNET. Moreover, we have tabulated the possible attacks on SecureSurgiNET along with the devised defensive measures. Finally, we also present a time complexity analysis of the SecureSurgiNET through simulations. © The Author(s) 2019

Measurement of natural frequency and mechanical damping of thin brass diaphragm by pulsed laser generated vibrations

Damped harmonic oscillator model based fitting of nanosecond pulsed laser induced amplitude variations of clamped vibrating circular plate is used to estimate the mechanical damping and natural frequency of the sample in current work. Laser Pulses of 50 mJ energy, 20 ns duration, and focused at a spot of 4 mm diameter at the center of the circular thin brass sheet of 100 µm thickness is used to generate vibrations in the target. Quadrature Michelson interferometer (QMI) with CW laser focused on the opposite side of the target surface is used to measure the amplitude of vibrations. Variations of fringe frequencies are identified in the frequency domain. Finite element based numerical modal analyses are also performed in ANSYS Workbench for the verification of experimental results for the same geometry and materials. Experimental frequencies of vibrations are found to match nearly 2 percent of FEM modes. Moreover, Elastic parameters are also found using the first two mode frequencies and a reasonable agreement is observed while comparing with the elastic parameter data of brass. Current work in itself is a unique attempt of getting mechanical parameters for the determination of elastic parameters in a single laser pulse impulse excited measurement for thin clamped targets

A review of virtual reality applications in an educational domain

The Practicality of Virtual Reality Applications in Education: Limitations and Recommendations

The use of virtual reality applications has grown tremendously in recent years. Virtual reality applications in the education domain have many benefits: they engage students, arouse students' curiosity, ease the communication of information, and motivate the students to improve their learning and performance. Despite literature showing that there has been a clear development in the education domain that shows improvement in students' learning skills, its application in Higher Education Institutions (HEIs) is limited to certain courses and fields. Furthermore, there has also been under-utilization and misutilization of virtual reality applications. Thus, the primary research question in this paper would be what the issues of the practicality of virtual reality applications for HEIs are. This paper aims to look at practicality issues to understand why VR is underutilized, particularly in HEIs. A review of the literature based on seventeen papers published between 2010 and 2020 taken from databases such as Science Direct, Ebscohost, and Scopus has found that despite the positive continuous intention to use VR applications, there are many issues regarding their practicality, such as the affordability of VR application tools, the technology-savviness of instructors, as well as the sustainability of VR use. This paper is significant as it explored and identified the practical issues of why VR applications are underused and provides practical suggestions to overcome these issues of practicality. It is hoped that HEIs would not allow these limitations to hinder the use of VR applications so that the students of this era, who are digital natives, would learn and perform better with VR applications; thus, making the use of VR applications in HEIs more widespread
