AES-CCMP 256 construction used in 802.11-2012 standard is strong enough in nonmobile devices in terms of security but is not optimized in resource usage.
1. The K12 Computer Science Framework is a high-level set of guidelines that informs the development of standards, curriculum, course pathways, and professional development. 5. At all levels, students should be able to use well-defined abstractions that hide complexity. Figure 5.16 shows the trend of the different performance metrics across K-NN and ENS1 algorithm. assistive devices provide capabilities such as scanning written information and converting it to speech. A Social Computing-Based CeSMO Research Framework. Download a complete or abridged copyof the framework statements viewed by grade band. %
Crosscutting Concepts: HumanComputer Interaction; Privacy and Security, Connections Within Framework: K2.Data and Analysis.Storage; K2.Data and Analysis.Visualization and Transformation. Crosscutting Concepts: System Relationships; HumanComputer Interaction. Access to tools may be limited by factors including cost, training, and availability. Figure 7.1. Examples of mathematical operations include those related to aggregation, such as summing and averaging. A community is created by people who share and provide feedback on one anothers creations. Eventually, students should include more factors in their evaluations, such as how efficiency affects feasibility or whether a proposed approach raises ethical concerns. Connection Within Framework: K2.Data and Analysis.Storage. Crosscutting Concepts: Privacy and Security; Communication and Coordination, Connection Within Framework: K2.Impacts of Computing.Safety, Law, and Ethics. For example, students could create an app to solve a community problem that connects to an online database through an application programming interface (API). An example of decomposition is preparing for a party: it involves inviting guests, making food, and setting the table. An example of a nested conditional structure is deciding what to do based on the weather outside. Older students should engage in active listening by using questioning skills and should respond empathetically to others. the planned design is expressed in a programming language (code) that can be made to run on a computing device. 1. This system includes three layers as follows: Fig. Eventually, testing should become a deliberate process that is more iterative, systematic, and proactive. Recursion is a control technique in which a procedure calls itself and is appropriate when problems can be expressed in terms of smaller versions of themselves. An algorithm that is generalizable to many situations can produce different outputs, based on a wide range of inputs. A medical device can be embedded inside a person to monitor and regulate his or her health. The first social media information processing and standardization component focuses on collecting and processing in real or near real time CeSMO-related social media information, and feeding the information to other components. An example of a design constraint is that mobile applications must be optimized for small screens and limited battery life. As they progress, students should understand that computers can model real-world phenomena, and they should use existing computer simulations to learn about real-world systems. 2 0 obj
Using generalized solutions and parts of solutions designed for broad reuse simplifies the development process by managing complexity. Online piracy, the illegal copying of materials, is facilitated by the ability to make identical-quality copies of digital media with little effort. Solicit and incorporate feedback from, and provide constructive feedback to, team members and other stakeholders. }
To create a free After students have had experience cultivating working relationships within teams (P2.1), they should gain experience working in particular team roles. Evaluate whether it is appropriate and feasible to solve a problem computationally. border-top-right-radius: 0px;
For example, computers can perform multiple complex calculations much faster and with greater accuracy than people. Later on, they should modify or remix parts of existing programs to develop something new or to add more advanced features and complexity. Students at all grade levels should be able to represent patterns, processes, or phenomena. Readability refers to how clear the program is to other programmers and can be improved through documentation. The timely and reliable access to data and information services by authorized users, referred to as availability, is ensured through adequate bandwidth, backups, and other measures. Articulate ideas responsibly by observing intellectual property rights and giving appropriate attribution. Data can be collected from either individual devices or systems. background-color: #ffffff;
Storing data on a cloud-based, redundant storage system may increase accessibility but reduce security, as it can be accessed online easily, even by unauthorized users. Furthermore, historical monitoring, trend analysis, and forecasting of degradation or failure can be conducted after multisource data is collected and archived to form large databases. Required fields are marked *. 5 0 obj
The development of these skills in grades K-12 is a critical component of Security measures may include physical security tokens, two-factor authentication, and biometric verification, but every security measure involves tradeoffs between the accessibility and security of the system. However, the build and evaluate loops used to produce the information market are informed by foundational theories and methodologies rooted in reference disciplines such as economics (experimental and behavioral), computer science and engineering, finance, psychology, and political science. Considering the needs of diverse users during the design process is essential to producing inclusive computational products. Connection Within Framework:912.Algorithms and Programming.Program Development. Your email address will not be published. As they progress, they should ask clarifying questions to understand whether a problem or part of a problem can be solved using a computational approach. We discuss the defining characteristics of CeSMOs and argue that these characteristics make systematic investigation of CeSMOs in the traditional ISI research framework extremely difficult. Incorporating these perspectives involves understanding the personal, ethical, social, economic, and cultural contexts in which people operate. Future research issues are also discussed in this chapter. For example, students could provide a project overview and ask for input from users. }
A procedure is a module (a group of instructions within a program) that performs a particular task. A common tradeoff in program development is sometimes referred to as Fast/Good/Cheap: Pick Two: one can develop software quickly, with high quality, or with little use of resources (for example, money or number of people), but the project manager may choose only two of the three criteria. For example, sprites (character images) can be moved and turned, numbers can be added or subtracted, and pictures can be recolored or cropped. It is a collection of helper modules , classes , objects , functions , pre-written code , An example of noise would be the first few seconds of a sample in which an audio sensor collects extraneous sound created by the user positioning the sensor. 912.Networks and the Internet.Cybersecurity, A list is a common type of data structure that is used to facilitate the efficient storage, ordering, and retrieval of values and various other operations on its contents. Ian H. Witten, David M. Nichols, in How to Build a Digital Library (Second Edition), 2010. Because computers make guessing weak passwords easy, strong passwords have characteristics that make them more time-intensive to break. Other equity deficits, such as minimal exposure to computing, access to education, and training opportunities, are related to larger, systemic problems in society. Choosing one operating system over another involves the tradeoff of capability and compatibility, such as which apps can be installed or which devices can be connected. Connection Within Framework: K2.Computing Systems.Devices. Data redundancies and backups are useful for restoring data when integrity is compromised. Data redundancies and backups are useful for restoring data when integrity is compromised. Examples of system components that may need troubleshooting are physical and wireless connections, peripheral equipment, and network hardware. All information, including instructions, is encoded as bits. However, existing literature on information markets and its current knowledge base might tempt researchers to black box the market, thus, undermining the importance of its interaction with the environment and downplaying the impacts of its technological and structural aspects on the effectiveness and efficiency of organizations adopting information markets [60,61]. Chapter 8 conducts an empirical study to investigate the performance characteristics of representative machine learning methods in cultural modeling. Developmentally appropriate ways to solve problems include debugging simple programs and seeking help by clearly describing a problem (for example, The computer wont turn on, The pointer on the screen wont move, or I lost the web page.) Knowing how to diagnose or troubleshoot a problem with a computing system is not expected. (Contains 1 note, 7 tables and 1 figure. text-align:left;
Early on, with teacher scaffolding, students should seek help and share ideas to achieve a particular purpose. Boards are the best place to save images and video clips. JFIF x x ZExif MM * J Q Q tQ t C Errors in survey data are cleaned up to remove spurious or inappropriate responses. The Getty Images design is a trademark of Getty Images. Connection Within Framework: K2.Impacts of Computing.Culture. Also, the attention required to follow GPS directions can lead to accidents due to distracted driving. The research paradigm is an Action Research that involves cycles of data collection, examination, evaluation, and application of results. Procedures that are defined with parameters are generalizable to many situations and will produce different outputs based on a wide range of inputs (arguments). The data obtained by ground sensors are usually transferred to an on-site server by wired or wireless networks. They should also manage project workflow using agendas and timelines and should evaluate workflow to identify areas for improvement. endobj
However, this is a major undertaking, which is why we have based this book on Greenstone2 rather than the newer version. Examples of events include mouse clicks, typing on the keyboard, and collisions between objects. Some visual, blocks-based languages do not have explicitly declared types but still have certain operations that apply only to particular types of data in a program. Chan, in Agile Manufacturing: The 21st Century Competitive Strategy, 2001. Social computing represents a new computing paradigm. In applications that run on the same computer as the digital library system, the communication protocol can be bypassed in favor of direct procedure calls using an application programming interface. The third layer analyses and exploits the database in order to construct maintenance planning models. Connection Within Framework: 35.Data and Analysis.Collection. Privacy should be considered when posting information online; such information can persist for a long time and be accessed by others, even unintended viewers. For example, a series of days might be grouped by temperature, air pressure, and humidity and later categorized as fair, mild, or extreme weather. For example, emotions must be subjectively evaluated on an individual basis and are thus difficult to measure across a population. This coordination among many computing devices allows a person to voice call a friend or video chat with a family member. For example. Security attacks often start with personal information that is publicly available online. The academia has a mission to contribute knowledge to the local community. As they progress, students should identify patterns as opportunities for abstraction, such as recognizing repeated patterns of code that could be more efficiently implemented as a loop. Designing a robot requires choosing both hardware and software and may involve a tradeoff between the potential for customization and ease of use. It will be checked whether AES-CCMP 256 is cost-effective to run in lower rounds. The 7 Core Practices. There are privacy implications when files contain metadata, such as the location where a photograph was taken. Data types vary by programming language, but many have types for numbers and text. Recursion is an optional concept at this level. Implementation includes the choice of programming language, which affects the time and effort required to create a program. a monitoring device installed in a motor vehicle can track a persons driving patterns and habits. For example, students can test their program with inputs associated with all potential scenarios. The K12 Computer Science Framework comes at a time when education systems are adapting to a 21st century vision of students who are not just computer users but also computationally literate creators who are proficient in the concepts and practices of computer science. There are many examples of protocols including TCP/IP (Transmission Control Protocol/Internet Protocol) and HTTP (Hypertext Transfer Protocol), which serve as the foundation for formatting and transmitting messages and data, including pages on the World Wide Web. For example, pair programming is a collaborative process that promotes giving and receiving feedback. Designing a robot requires choosing both hardware and software and may involve a tradeoff between the potential for customization and ease of use. Next phase would be creating new modes of AES-CCMP for mobile devices. Early on, they should learn strategies for working with team members who possess varying individual strengths. Connections Within Framework: K2.Computing Systems.Devices; K2.Computing Systems.Hardware and Software. Data points can be clustered by a number of commonalities without a category label. System software manages a computing devices resources so that software can interact with hardware. Legal issues in computing, such as those related to the use of the Internet, cover many areas of law, reflect an evolving technological field, and can involve tradeoffs. Just as pilots use checklists to troubleshoot problems with aircraft systems, people can use a similar, structured process to troubleshoot problems with computing systems and ensure that potential solutions are not overlooked. For example, in the early grades, students could collaboratively brainstorm by writing on a whiteboard. Automated regression testing helps minimize the problem of checking for undesired side effects of recently committed changes. Systematic analysis includes the testing of program performance and functionality, followed by end-user testing. Chapter 4 presents a probabilistic plan inference approach to forecasting group behavior.
Crosscutting Concepts: Abstraction; Privacy and Security. Readability refers to how clear the program is to other programmers and can be improved through documentation. For example, a class can discuss ideas in the same school or in another nation through interactive webinars. Rules guiding interactions in the world, such as stranger danger, apply to online environments as well. From the user's point of view, all other changes when upgrading to Greenstone3 will be invisible. 2. Older students should identify more complex problems that involve multiple criteria and constraints. Procedures are invoked to repeat groups of instructions. This is a planning stage in which the programmers gather information about the problem and sketch out a solution. Lastly, rail life prediction models can be derived from big data and such basic models. Common Core State Standards (CCSS)-English Language Arts. Figure 3.1 shows an operational framework that will be followed in this study. It consists of five major components. Connection Within Framework: 68.Computing Systems.Hardware and Software. 3. Connection Within Framework: K2.Data and Analysis.Inference and Models. This allows people to see the published e-framework service components and those currently under development. At this level, students deepen their understanding of variables, including when and how to declare and name new variables. Following the above. 68.Computing Systems.Hardware and Software. Tradeoffs are associated with choosing different types of lists. kernel, or bus, is not expected at this level. As students progress, they should advocate for their peers when accommodations, such as an assistive-technology peripheral device, are needed for someone to use a computational artifact. Creating For example, students might create a simple producerconsumer ecosystem model using a programming tool. System software manages a computing devices resources so that software can interact with hardware. Students should analyze and evaluate these models against real-world observations. Streamline your workflow with our best-in-class digital asset management system. Crosscutting Concepts: Communication and Coordination; System Relationships, Connection Within Framework: 35.Networks In this way, students will examine and correct their own thinking. text-align:left}
It provides a foundation on which software . }
At this stage, these modules, which combine both data and procedures, can be designed and documented for reuse in other programs. The data that is collected about an individual and potential inferences made from that data can have implications for privacy. As they progress, students should use methods for giving all group members a chance to participate. attached light sensor to detect changes in brightness, whereas the light sensor depends on the robot for power. The implementation would be in counter mode. Crosscutting Concepts: Privacy and Security; Abstraction, Connections Within Framework: 68.Algorithms and Programming.Algorithms; 68.Impacts of Computing.Culture. Computers can represent a variety of data using discrete values at many different levels, such as characters, numbers, and bits. facial recognition device can be integrated into a security system to identify a person. Examples of complex troubleshooting strategies include resolving connectivity problems, adjusting system configurations and settings, ensuring hardware and software compatibility, and transferring data from one device to another. They can also create an animation to model a phenomenon, such as evaporation. Workshop and tutorial material have been tested to ensure that they work equally well with Greenstone3. Older students should model phenomena as systems, with rules governing the interactions within the system. Eventually, students should independently organize their own teams and create common goals, expectations, and equitable workloads. Collaborative computing is the process of performing a computational task by working in pairs and on teams. The creation of integrated or embedded systems is not an expectation at this level.
