Timss 2003

Mathematical tasks can be classified in a number of ways. While Galbraith & Haines (2001), for example, distinguish among mechanical, interpretative and constructive tasks, Smith et at. (1996) divide tasks into the following three categories: (A) factual knowledge, comprehension and routine use of procedures; (B) information transfer and application in new situations; and (C) identifying and interpreting; implications, conjectures and comparisons and evaluation. Having briefly summarized these and some other mathematical tasks classifications, this paper presents and critically examines the TIMSS 2003 mathematics cognitive domains. As a part of the TIMSS 2003 project these cognitive domains - knowing facts and roles, vising concepts, solving routine problems, and reasoning - were operationalized for the content domain of algebra in grade 8 and the paper gives a sample of the developed tasks that are fully available on the Internet (see www.matf.bg.ac.yu/cdjk/drafl2.pdfanA www.matf.bg.ac.yn/cdjk/yu20item.pdf). Through the examination and operationalization of the TIMSS assessment framework several implications for research and professional development of mathematics teachers have been realized. The article presents three of them dealing with an elaborated item classification, its empirical validation and a didactical preparation of teachers including operationalizations of the chosen task classification/taxonomy.

Critical evaluation skills when using online information are considered important in many research and education frameworks; critical thinking and information literacy are cited as key twenty-first century skills for students. Higher education may play a special role in promoting students' skills in critically evaluating (online) sources. Today, higher education students are more likely to use the Internet instead of offline sources such as textbooks when studying for exams. However, far from being a value-neutral, curated learning environment, the Internet poses various challenges, including a large amount of incomplete, contradictory, erroneous, and biased information. With low barriers to online publication, the responsibility to access, select, process, and use suitable relevant and trustworthy information rests with the (self-directed) learner. Despite the central importance of critically evaluating online information, its assessment in higher education is still an emerging field. In this paper, we present a newly developed theoretical-conceptual framework for Critical Online Reasoning (COR), situated in relation to prior approaches (“information problem-solving,” “multiple-source comprehension,” “web credibility,” “informal argumentation,” “critical thinking”), along with an evidence-centered assessment framework and its preliminary validation. In 2016, the Stanford History Education Group developed and validated the assessment of Civic Online Reasoning for the United States. At the college level, this assessment holistically measures students' web searches and evaluation of online information using open Internet searches and real websites. Our initial adaptation and validation indicated a need to further develop the construct and assessment framework for evaluating higher education students in Germany across disciplines over their course of studies. Based on our literature review and prior analyses, we classified COR abilities into three uniquely combined facets: (i) online information acquisition, (ii) critical information evaluation, and (iii) reasoning based on evidence, argumentation, and synthesis. We modeled COR ability from a behavior, content, process, and development perspective, specifying scoring rubrics in an evidence-centered design. Preliminary validation results from expert interviews and content analysis indicated that the assessment covers typical online media and challenges for higher education students in Germany and contains cues to tap modeled COR abilities. We close with a discussion of ongoing research and potentials for future development.

Recent progress in learning indicates the importance of students to be active in invents things rather than passive recipients. Smart Classrooms can make a noticeable change in how teachers can teach and learners can learn. The objective of the project presented in this paper is to propose a smart algorithm that provides a means of achieving a smart classroom environment in which most of the manual processes are automated and provides an efficient way of interconnecting multiple classes, thereby providing a unique way for information transfer. The proposed algorithm uses the Internet of Things to communicate between various classrooms and transmit/receive the required information. An embedded module installed in each classroom can collect information such as attendance detail, teacher’s location, and updates the information in the server for future use. These details are then used for some critical purposes, such as sending circulars, calling a particular teacher immediately to the office, etc

Reputation Building

The article aims at drawing attention to opportunities of reputation management by researchers using new media, considering the importance of internet tools for image creation and identifying opportunities and threats. The research problem of the article focuses on answers to the question formulated as follows: What might the possible importance of the Internet for reputation building be? The problem relates to the issue of researchers’ active participation in creating and shaping their reputation online. The presented considerations have been based on literature and studies on the subject. The article attempts to clarify the distinction between the concepts of identity, image, and reputation. It discusses image-creating factors and refers to the question of immanent credibility and guise in research. The author describes examples of internet tools and points to their importance for reputation management, which concerns the sum of partial images accumulating over time. Communication plays an important role in building reputation. Owing to its availability, interactivity and variety of forms, as well as the speed of information transfer, the Internet has become an indispensable channel of communication. All researchers should recognise the fact in order to build their reputation thoughtfully. Their reputation involves a multitude of accumulated images formed as a result of interactions between factors associated with the subjects themselves, information the recipients obtain, and factors relating to the recipients. The conclusions of the study point to the necessity of reputation management by planned and deliberate actions taking advantage of internet tools. Thus, every effort should be made to prevent a situation where reputation is shaped irrespective of the interested person’s participation.

The information transfer protocol that supports the modern Internet with its hundreds of thousands of petabytes per month to billions of Internet users across the world was designed in 1981, and it lacks the capacity to properly ensure the security and stability of the Internet today. Features such as the prevention of network attacks, a large address space for the increasing number of devices, verification of the source of an Internet request, and so on are all absent from the current architecture. This paper seeks to review, summarize, and compare six proposals submitted to address the issues IP faces: the Accountable Internet Protocol, the Expressive Internet Architecture, MobilityFirst, Passport, StopIt, and the Traffic Validation Architecture. Finally, the paper details a protocol design that not only is feasible to adopt with the present infrastructure/computing power but also addresses some of the pressing issues of IP, with particular focus on the address space, mitigation of network attacks, and source verification.

The Internet Of Things

This chapter discusses the opportunities for new ubiquitous computing technologies, with concentration on the Internet of Things (IoT), to improve patient safety and quality. The authors focus on elective or planned surgical interventions, although the technology is applicable to primary and trauma care. The chapter is divided into three main sections with section 1 covering medical error issues and mechanisms, section 2 introducing Internet of Things, and section 3 discussing how IoT capabilities may address and reduce medical errors. The authors explore the existing theory of errors expounded by Reason (Reason, 2000, 1998; Leape, 1994) to identify perception-, decision-, and knowledge-based medical errors and related processes, environments, and cultural drivers causing error. The authors then introduce the technology of the Internet of Things and identify a range of capabilities from sensing, tracking, control, cooperative, and semantic reasoning. They then show how these new capabilities might be applied to reduce the errors expounded by the discussed error theories. They identify that: IoT enables augmentation of objects, which provides a massive increase in information transfer, thus improving clinician perception and support for decision-making and problem solving; IoT provides a host of additional observers and opportunities, which can shift the focus of overworked clinicians from constant monitoring to undertaking complex actions, such as decision making and care; IoT networks of sensors and actuators, through the addition of semantic and contextual rules, support decision making and facilitate automated monitoring and control of pervasive safety-monitored health environments, thus reducing clinician workload.
