Enhancing learning with authoritative actions: Reflective practice of positive power

Drawing from classic power perspective, my reflective practice illuminates how power action, traditionally recognized as negative and detrimental to teaching process and learning outcomes, could be shaped in a positive way to enhance learning. Insights gained from this action research set in a politically charged and culturally homogenous environment provide critical perspective to the research community and challenge traditional practices of teaching and learning. Implications gained call for attention to critical perspective of empirical studies that could provide lessons for educators and researchers to create a more effective teaching and learning environment with authoritative power. An action framework is created in the end to illustrate how the positive authoritative process can be achieved

Authentication of Students and Students’ Work in E-Learning : Report for the Development Bid of Academic Year 2010/11

Global e-learning market is projected to reach $107.3 billion by 2015 according to a new report by The Global Industry Analyst (Analyst 2010). The popularity and growth of the online programmes within the School of Computer Science obviously is in line with this projection. However, also on the rise are students’ dishonesty and cheating in the open and virtual environment of e-learning courses (Shepherd 2008). Institutions offering e-learning programmes are facing the challenges of deterring and detecting these misbehaviours by introducing security mechanisms to the current e-learning platforms. In particular, authenticating that a registered student indeed takes an online assessment, e.g., an exam or a coursework, is essential for the institutions to give the credit to the correct candidate. Authenticating a student is to ensure that a student is indeed who he says he is. Authenticating a student’s work goes one step further to ensure that an authenticated student indeed does the submitted work himself. This report is to investigate and compare current possible techniques and solutions for authenticating distance learning student and/or their work remotely for the elearning programmes. The report also aims to recommend some solutions that fit with UH StudyNet platform.Submitted Versio

Student Evaluation, Basic Element for Quality Improvement in the Higher Education

The student is the person who, through certain native or gained qualities, assimilates the information and knowledge provided by the Professor. He is the main beneficiary of the educational system, because the main educational effects are registered at his level: the social effects (the improvement of the individual’s inter-human relations inside a society, the healthier behaviour of the educated persons etc.) and the economical effects (especially materialized as supplementary incomes for the higher-educated persons). Therefore, we can say that the student, together with the teacher, occupies a central position in the educational system.education; evaluation; student; tests.

The DLV System for Knowledge Representation and Reasoning

This paper presents the DLV system, which is widely considered the state-of-the-art implementation of disjunctive logic programming, and addresses several aspects. As for problem solving, we provide a formal definition of its kernel language, function-free disjunctive logic programs (also known as disjunctive datalog), extended by weak constraints, which are a powerful tool to express optimization problems. We then illustrate the usage of DLV as a tool for knowledge representation and reasoning, describing a new declarative programming methodology which allows one to encode complex problems (up to $\Delta^P_3$-complete problems) in a declarative fashion. On the foundational side, we provide a detailed analysis of the computational complexity of the language of DLV, and by deriving new complexity results we chart a complete picture of the complexity of this language and important fragments thereof. Furthermore, we illustrate the general architecture of the DLV system which has been influenced by these results. As for applications, we overview application front-ends which have been developed on top of DLV to solve specific knowledge representation tasks, and we briefly describe the main international projects investigating the potential of the system for industrial exploitation. Finally, we report about thorough experimentation and benchmarking, which has been carried out to assess the efficiency of the system. The experimental results confirm the solidity of DLV and highlight its potential for emerging application areas like knowledge management and information integration.Comment: 56 pages, 9 figures, 6 table

Introductory programming: a systematic literature review

As computing becomes a mainstream discipline embedded in the school curriculum and acts as an enabler for an increasing range of academic disciplines in higher education, the literature on introductory programming is growing. Although there have been several reviews that focus on specific aspects of introductory programming, there has been no broad overview of the literature exploring recent trends across the breadth of introductory programming. This paper is the report of an ITiCSE working group that conducted a systematic review in order to gain an overview of the introductory programming literature. Partitioning the literature into papers addressing the student, teaching, the curriculum, and assessment, we explore trends, highlight advances in knowledge over the past 15 years, and indicate possible directions for future research

Disease modelling using evolved discriminate function

Precocious diagnosis increases the survival time and patient quality of life. It is a binary classification, exhaustively studied in the literature. This paper innovates proposing the application of genetic programming to obtain a discriminate function. This function contains the disease dynamics used to classify the patients with as little false negative diagnosis as possible. If its value is greater than zero then it means that the patient is ill, otherwise healthy. A graphical representation is proposed to show the influence of each dataset attribute in the discriminate function. The experiment deals with Breast Cancer and Thrombosis & Collagen diseases diagnosis. The main conclusion is that the discriminate function is able to classify the patient using numerical clinical data, and the graphical representation displays patterns that allow understanding of the model

Understanding the Education Trajectories of Young Black Men in New York City: Elementary and Middle-School Years

Making targeted decisions about how, when, and where to intervene to improve educational outcomes for black males requires understanding the complex pathways that shape these outcomes. This study, undertaken for the Black Male Donor Collaborative, uses longitudinal data on a cohort of black males from New York City Schools to gain insights about the different possible student paths, with specific focuses on middle school and math scale scores

Final Exam Scores in Introductory Economics Courses: Effect of Course Delivery Method and Proctoring

There is a small but growing body of research exploring student learning in online courses. The current study compares student performance on the final exam in introductory economics courses taught online and in the classroom and considers the effect of proctoring the final exam. Students who took a course in the classroom did better on a proctored final exam than those taking the course online.cheating, economics, online delivery, proctored exams, Teaching/Communication/Extension/Profession,
