ForgeFX - 3D Topographic Map Simulation Software - 3 views

  •  
    This real-time 3D simulation illustrates how topographic maps are created and used to depict changes in elevation. A topographic map is characterized by large-scale detail and quantitative representation of relief using contour lines. Rendered in real-time 3D, it is easy to understand how topographic maps are created since the simulation shows the same virtual environment in both a 3D mesh and 2D map format.

How to Fix Our Math Education - NYTimes.com - 63 views

  • the assumption that there is a single established body of mathematical skills that everyone needs to know to be prepared for 21st-century careers. This assumption is wrong. The truth is that different sets of math skills are useful for different careers, and our math education should be changed to reflect this fact.
  • Today, American high schools offer a sequence of algebra, geometry, more algebra, pre-calculus and calculus (or a “reform” version in which these topics are interwoven). This has been codified by the Common Core State Standards, recently adopted by more than 40 states. This highly abstract curriculum is simply not the best way to prepare a vast majority of high school students for life.
  • A math curriculum that focused on real-life problems would still expose students to the abstract tools of mathematics, especially the manipulation of unknown quantities. But there is a world of difference between teaching “pure” math, with no context, and teaching relevant problems that will lead students to appreciate how a mathematical formula models and clarifies real-world situations.

  • For instance, how often do most adults encounter a situation in which they need to solve a quadratic equation? Do they need to know what constitutes a “group of transformations” or a “complex number”? Of course professional mathematicians, physicists and engineers need to know all this, but most citizens would be better served by studying how mortgages are priced, how computers are programmed and how the statistical results of a medical trial are to be understood.
  • Imagine replacing the sequence of algebra, geometry and calculus with a sequence of finance, data and basic engineering.
  • Traditionalists will object that the standard curriculum teaches valuable abstract reasoning, even if the specific skills acquired are not immediately useful in later life. A generation ago, traditionalists were also arguing that studying Latin, though it had no practical application, helped students develop unique linguistic skills. We believe that studying applied math, like learning living languages, provides both useable knowledge and abstract skills.
  • In math, what we need is “quantitative literacy,” the ability to make quantitative connections whenever life requires (as when we are confronted with conflicting medical test results but need to decide whether to undergo a further procedure) and “mathematical modeling,” the ability to move practically between everyday problems and mathematical formulations (as when we decide whether it is better to buy or lease a new car).

  • many of our young households here are now coming out with massive amounts of student loan debt.
  • Lower incomes, more debt, and less job security.  What this translated to in Japan was stagnant home prices for 20 full years.  We are nearing our 10 year bear market anniversary in real estate so another 10 is not impossible.  What can change this?  Higher median household incomes across the nation but at a time when gas costs $4 a gallon, grocery prices are increasing, college tuition is in a bubble, and the financial system operates with no reform and exploits the bubble of the day, it is hard to see why Americans would be pushing home prices higher.

Role and Function of Theory in Online Education Development and Delivery - 3 views

  • According to Bonk and Reynolds (1997), to promote higher-order thinking on the Web, online learning must create challenging activities that enable learners to link new information to old, acquire meaningful knowledge, and use their metacognitive abilities; hence, it is the instructional strategy and not the technology that influences the quality of learning.
  • However, it is not the computer per se that makes students learn, but the design of the real-life models and simulations, and the students' interaction with those models and simulations. The computer is merely the vehicle that provides the processing capability and delivers the instruction to learners (Clark, 2001).
  • ...35 more annotations...
  • Online learning allows for flexibility of access, from anywhere and usually at anytime—essentially, it allows participants to collapse time and space (Cole, 2000)—however, the learning materials must be designed properly to engage the learner and promote learning.
  • Cognitive psychology claims that learning involves the use of memory, motivation, and thinking, and that reflection plays an important part in learning.
  • The development of effective online learning materials should be based on proven and sound learning theories.
  • Early computer learning systems were designed based on a behaviorist approach to learning. The behaviorist school of thought, influenced by Thorndike (1913), Pavlov (1927), and Skinner (1974), postulates that learning is a change in observable behavior caused by external stimuli in the environment (Skinner, 1974).
  • Therefore, before any learning materials are developed, educators must, tacitly or explicitly, know the principles of learning and how students learn.
  • Constructivist theorists claim that learners interpret information and the world according to their personal reality, and that they learn by observation, processing, and interpretation, and then personalize the information into personal knowledge (Cooper, 1993; Wilson, 1997).
  • The design of online learning materials can include principles from all three. According to Ertmer and Newby (1993), the three schools of thought can in fact be used as a taxonomy for learning. Behaviorists' strategies can be used to teach the “what” (facts), cognitive strategies can be used to teach the “how” (processes and principles), and constructivist strategies can be used to teach the “why” (higher level thinking that promotes personal meaning and situated and contextual learning).
  • The behaviorist school sees the mind as a “black box,” in the sense that a response to a stimulus can be observed quantitatively, totally ignoring the effect of thought processes occurring in the mind.
  • Learners should be told the explicit outcomes of the learning so that they can set expectations and can judge for themselves whether or not they have achieved the outcome of the online lesson. 2.  Learners must be tested to determine whether or not they have achieved the learning outcome. Online testing or other forms of testing and assessment should be integrated into the learning sequence to check the learner's achievement level and to provide appropriate feedback. 3.  Learning materials must be sequenced appropriately to promote learning. The sequencing could take the form of simple to complex, known to unknown, and knowledge to application. 4.  Learners must be provided with feedback so that they can monitor how they are doing and take corrective action if required.
  • Cognitivists see learning as an internal process that involves memory, thinking, reflection, abstraction, motivation, and meta-cognition.
  • Online instruction must use strategies to allow learners to attend to the learning materials so that they can be transferred from the senses to the sensory store and then to working memory.
  • Online learning strategies must present the materials and use strategies to enable students to process the materials efficiently.
  • information should be organized or chunked in pieces of appropriate size to facilitate processing.
  • Use advance organizers to activate an existing cognitive structure or to provide the information to incorporate the details of the lesson (Ausubel, 1960).
  • Use pre-instructional questions to set expectations and to activate the learners' existing knowledge structure.
  • Use prerequisite test questions to activate the prerequisite knowledge structure required for learning the new materials.
  • To facilitate deep processing, learners should be asked to generate the information maps during the learning process or as a summary activity after the lesson (Bonk & Reynolds, 1997).
  • The cognitive school recognizes the importance of individual differences, and of including a variety of learning strategies in online instruction to accommodate those differences
  • The Kolb Learning Style Inventory (LSI) (Kolb, 1984) looks at how learners perceive and process information, whereas the Myers-Briggs Type Indicator (Myers, 1978) uses dichotomous scales to measure extroversion versus introversion, sensing versus intuition, thinking versus feeling, and judging versus perception. In the following discussion, we consider the Kolb Learning Style Inventory.
  • Attention: Capture the learners' attention at the start of the lesson and maintain it throughout the lesson. The online learning materials must include an activity at the start of the learning session to connect with the learners. Relevance: Inform learners of the importance of the lesson and how taking the lesson could benefit them. Strategies could include describing how learners will benefit from taking the lesson, and how they can use what they learn in real-life situations. This strategy helps to contextualize the learning and make it more meaningful, thereby maintaining interest throughout the learning session. Confidence: Use strategies such as designing for success and informing learners of the lesson expectations. Design for success by sequencing from simple to complex, or known to unknown, and use a competency-based approach where learners are given the opportunity to use different strategies to complete the lesson. Inform learners of the lesson outcome and provide ongoing encouragement to complete the lesson. Satisfaction: Provide feedback on performance and allow learners to apply what they learn in real-life situations. Learners like to know how they are doing, and they like to contextualize what they are learning by applying the information in real life.
  • Online strategies that facilitate the transfer of learning should be used to encourage application in different and real-life situations.
  • Constructivists see learners as being active rather than passive.
  • it is the individual learner's interpretation and processing of what is received through the senses that creates knowledge.
  • “the process of using a prior interpretation to construe a new or revised interpretation of the meaning of one's experience in order to guide future action” (p. 12).
  • Learning should be an active process. Keeping learners active doing meaningful activities results in high-level processing, which facilitates the creation of personalized meaning. Asking learners to apply the information in a practical situation is an active process, and facilitates personal interpretation and relevance.
  • Learners should construct their own knowledge rather than accepting that given by the instructor.
  • Collaborative and cooperative learning should be encouraged to facilitate constructivist learning (H
  • When assigning learners for group work, membership should be based on the expertise level and learning style of individual group members, so that individual team members can benefit from one another's strengths.
  •   Learners should be given control of the learning process
  • Learners should be given time and opportunity to reflect.
  • Learning should be made meaningful for learners. The learning materials should include examples that relate to students, so that they can make sense of the information.
  • Learning should be interactive to promote higher-level learning and social presence, and to help develop personal meaning. According to Heinich et al. (2002), learning is the development of new knowledge, skills, and attitudes as the learner interacts with information and the environment. Interaction is also critical to creating a sense of presence and a sense of community for online learners, and to promoting transformational learning (Murphy & Cifuentes, 2001). Learners receive the learning materials through the technology, process the information, and then personalize and contextualize the information.
  • Figure 1-6. Components of effective online learning.
  • Behaviorist strategies can be used to teach the facts (what); cognitivist strategies to teach the principles and processes (how); and constructivist strategies to teach the real-life and personal applications and contextual learning. There is a shift toward constructive learning, in which learners are given the opportunity to construct their own meaning from the information presented during the online sessions. The use of learning objects to promote flexibility and reuse of online materials to meet the needs of individual learners will become more common in the future. Online learning materials will be designed in small coherent segments, so that they can be redesigned for different learners and different contexts. Finally, online learning will be increasingly diverse to respond to different learning cultures, styles, and motivations.
  • Online instruction occurs when learners use the Web to go through the sequence of instruction, to complete the learning activities, and to achieve learning outcomes and objectives (Ally, 2002; Ritchie & Hoffman, 1997).

      This is, of course, an overstatement, as not everyone is prepared, given their development and living conditions, to take advantage of Internet.
  • We’ve created happy little caskets inside which learning fits too neatly and tidily (like forums, learning management systems, and web conferencing platforms). We’ve timed learning down to the second, developed draconian quality assurance measures, built analytics to track every bit of minutiae, and we’ve championed the stalest, most banal forms of interaction — interaction buried beneath rubrics and quantitative assessment — interaction that looks the same every time in every course with every new set of students.

Taking the Information Plunge With Tinderbox | Mac.AppStorm - 146 views

  • Tinderbox “the tool for notes.”
  • The power of Tinderbox comes from its ability to display those notes in a number of different and helpful ways, and its array of mechanisms for manipulating those notes.
  • Tinderbox is a toolbox full of tools that let you play with information. DevonThink Pro is a better tool for research, particularly when linked with Devon Agent, OmniOutliner is a better outliner, Scrivener is a better writing tool, and Omnigraffle does a better job of drawing. All of these tools are great, but while they overlap some, they don’t cover everything Tinderbox does.

  • For many years, I have walked into large, complex businesses and attempted to identify what was going on and how it could be done better. My job was part Qualitative Research, part Quantitative Research, and part Political Analysis. Qualitative Research has a number of tools for analyzing interviews and playing with the data, teasing meaning out of diverse viewpoints. I used these tools effectively, but I wish I’d had Tinderbox earlier in my career because it would have made this job easier. Tinderbox is a far more useful tool for ‘right-brained’ qualitative analysis than most of the other tools I’ve worked with, but even that sells it short.
  • Very few people I’ve seen truly understand its character as a tool box for manipulating and exploring information.
  • I have been using TB for just over a year and it has become my second top application after Scrivener. (I also use DEVONThink Pro) I have planned a trilogy of novels on it, and a detailed timeline for the first novel. I’m currently editing the first novel, which is to come out in Feb 2112, and I have set up my Scrivener screen so that the timeline occupies the lower third of my screen (though the Apps can be viewed together in other ways).
  • As for the trilogy, the plan is a work in progress using map view. But the power to manipulate the characters, events and relationships, and run what-ifs, has far exceeded my expectations.

  • Second, in management and marketing, no strong consensus has emerged about what students ought to learn or how they ought to learn it.
  • Gains on the C.L.A. closely parallel the amount of time students reported spending on homework. Another explanation is the heavy prevalence of group assignments in business courses: the more time students spent studying in groups, the weaker their gains in the kinds of skills the C.L.A. measures.
  • The pedagogical theory is that managers need to function in groups, so a management education without such experiences would be like medical training without a residency. While some group projects are genuinely challenging, the consensus among students and professors is that they are one of the elements of business that make it easy to skate through college.

  •  
    Computer analyses of text characteristics are often used by reading teachers, researchers, and policy makers when selecting texts for students. The authors of this article identify components of language, discourse, and cognition that underlie traditional automated metrics of text difficulty and their new Coh-Metrix system. Coh-Metrix analyzes texts on multiple measures of language and discourse that are aligned with multilevel theoretical frameworks of comprehension. The authors discuss five major factors that account for most of the variance in texts across grade levels and text categories: word concreteness, syntactic simplicity, referential cohesion, causal cohesion, and narrativity. They consider the importance of both quantitative and qualitative characteristics of texts for assigning the right text to the right student at the right time.
