    1. What is the "ostrich instruction"? It’s an informal way to refer to an important legal principle, which is that deliberate avoidance of knowledge about one’s own illegal actions should not be a valid defence in law. It’s one of the reasons why, just over 15 years ago, American executives at the energy company Enron were found guilty even though their direct role in malfeasance at Enron wasn’t clear. They should and could have known about fraud, and they were found guilty. Enron has been pointed to as proof that wilful ignorance does not pay. But in my book I stress that that Enron is a fairly isolated case. As a number of other people have pointed out, from journalists Matt Taibbi and Jesse Eisenger to legal scholar Rena Steinzor, US authorities have had an abysmal record of successful prosecution of white-collar crime in recent decades. An American legal scholar based in the UK, Alexander Sarch, is doing important work on this topic. But he is an exception, and I’m a little critical of mainstream legal scholarship in my book. I suggest that legal scholars themselves have been acting ostrich-like about recent shifts in the law. For example, the old adage "ignorance of the law is no excuse" is increasingly waived in US courts when it comes to complex financial and tax crimes. This shift is one of the reasons why I argue that for many powerful and rich people, ignorance really is legal bliss.

      This is a salient point, and a leverage point.

    1. Programs that repeatedly reference the same variables enjoy good temporallocality..For programs with stride-k reference patterns, the smaller the stride, thebetter the spatial locality. Programs with stride-1 reference patterns have goodspatial locality. Programs that hop around memory with large strides havepoor spatial locality..Loops have good temporal and spatial locality with respect to instructionfetches. The smaller the loop body and the greater the number of loop it-erations, the better the locality.

      locality 总结起来的特点是什么?

    1. A number ofstudies have demonstrated that instructional videos that include gesture producesignificantly more learning for the people who watch them: viewers direct theirgaze more efficiently, pay more attention to essential information, and morereadily transfer what they have learned to new situations. Videos that incorporategesture seem to be especially helpful for those who begin with relatively littleknowledge of the concept being covered; for all learners, the beneficial effect ofgesture appears to be even stronger for video instruction than for live, in-personinstruction.

      Gestures can help viewers direct their attention to the most salient and important points in a conversation or a lecture. As a result, learning has been show to be improved in watching lectures with gestures.

      Learning using gestures has been shown to be stronger in video presentations over in-person instruction.

      test 指令的作用是什么?

    2. The cmp instructions set the condition codes according to the differences of theirtwo operands. They behave in the same way as the sub instructions, except thatthey set the condition codes without updating their destinations.

      cmp 指令集的作用是什么?

    3. By using a PC-relativeencoding of the jump targets, the instructions can be compactly encoded (requiringjust 2 bytes), and the object code can be shifted to different positions in memorywithout alteration.

      pc-relative encoding 的计算方式是什么,有什么优势?

    4. It is important to recognize that the suffixes forthese instructions denote different conditions and not different operand sizes. Forexample, instructions setl and setb denote “set less” and “set below,” not “setlong word” or “set byte.”

      set 指令的后缀代表的含义是什么?

      binary operation 的两个操作数可以是 memory location 吗?

    2. The destination operand must be a register.

    3. The ability of the leaq instruction to perform addition and limited forms ofmultiplication proves useful when compiling simple arithmetic expressions suchas this example.

      leaq 在什么情况下有用?

    4. logicallybe named movzlq, but this instruction does not exist. Instead, this type of datamovement can be implemented using a movl instruction having a register as thedestination. This technique takes advantage of the property that an instructiongenerating a 4-byte value with a register as the destination will fill the upper 4bytes with zeros.

      为什么在 movz 的指令中缺少 movzlq?

    5. in memory, to a register destination. Instructions in the movz class fill out theremaining bytes of the destination with zeros, while those in the movs class fillthem out by sign extension, replicating copies of the most significant bit of thesource operand.

      那两种 move 指令针对 copy smaller source 到 larger destination,他们的做法分别是什么?

    6. The source operand designates a value that is immediate, stored in a register,or stored in memory. The destination operand designates a location that is either aregister or a memory address. x86-64 imposes the restriction that a move instruc-tion cannot have both operands refer to memory locations. Copying a value fromone memory location to another requires two instructions—the first to load thesource value into a register, and the second to write this register value to the des-tination.

      move 的 source operand 和 destination operand 分别可以是哪些类型?

    7. The most general form is shown at the bottomof the table with syntax Imm(rb,ri,s). Such a reference has four components: animmediate offset Imm, a base register rb, an index register ri, and a scale factors, where s must be 1, 2, 4, or 8. Both the base and index must be 64-bit registers.The effective address is computed as Imm + R[rb] + R[ri] . s.

      访问 $$Imm(r_b, r_i, s)$$ 的内存应该如何计算,有哪些限制条件?

    1. he actual ratio of face-to-face to online instruction can differ greatly and still be considered hybrid instruction

      Really important for two reason - (1) we may not mean the same thing so we should clarify what we're talking about when in conversation on this important issue; and (2) What works in one course/setting may not work in another - great reminder to honor the unique nature of courses/settings.

    1. engages the learners and goes beyond their expectations.

      DOI: Creative Instruction - Engages learners and goes above thier expectations.

      Another interesting take on creative instruction. I like that they define it as going "beyond [learner] expectations".

    2. instruction that keeps learners motivated while still meeting the objectives of the instruction.

      DOI: Creative instruction - Motivating instruction that stays on task.

      Great definition that hints at what creative intruction looks like.

    1. The application and integration of video into the community of inquiry (CoI) framework can humanize instructor, social and cognitive presence for effective online learning. The concept of affordances and universal design for learning principles can be applied to design decisions when video is applied to support the CoI model. Knowing that video includes a variety of formats and options beyond the lecture-capture model is essential. Understanding a pedagogy of video – code breaking, meaning making, using, applying, and identifying persona – will ensure that video assets support critical and digital learning outcomes. Design with video can activate deeper reflective practice when applying location, integration, creation, annotation, collaboration, and curation of video assets. Issues when considering video integration into online learning spaces include quality/quantity, open/closed, actor/teacher, asynchronous/synchronous, or live/recorded video.

      Using video is more than content delivery. When employing universal design to the video content the asset will support critical and digital learning outcomes.

    1. The author, Stefan Hrastinski, is a Professor at the Division of Digital Learning and Director of Research Education at the Department of Learning in Engineering Sciences at KTH Royal Institute of Technology in Sweden. Hrastinski notes the term "blended learning" originated in the 1990's, but is often over generalized. Hrastinski proposes several blended learning models, blended learning conceptualizations, and proposes recomendations for future research.

    1. The authors present a study focused the differences of blended versus traditional instruction in terms of student performance. The study evaluates 53 undergraduate students enrolled in a "Physical Education in Early Childhood" course. Twenty-nine students were placed in a traditional course and 24 students were placed in a blended "experimental" group. The researchers concluded that "students who attended the course with blended instruction show higher performance."

    1. 15 Fall Scenarios

      The authors, Edward J. Maloney and Joshua Kim, wrote a total of 15 articles describing various scenarios for the university learning environment during COVID-19. This article summarizes each of these more detailed plans including "normal" and moving the Fall term to the Spring. They also describe various learning models including HyFlex, modularity, virtual, and remote.

    1. Online learning, blended learning, flipped learning, hybrid learning, flexible learning, open learning and distance education are all terms that are often used inter-changeably, but there are significant differences in meaning. More importantly, these forms of education, once considered somewhat esoteric and out of the mainstream of conventional education, are increasingly taking on greater significance and in some cases becoming mainstream themselves. As teachers and instructors become more familiar and confident with online learning and new technologies, there will be more innovative methods developing all the time.

      The author, Anthony Bates, holds a BA in Psychology and a Ph.D. in Educational Administration. He holds over 40 years of teaching experience. In this chapter he proposes online learning is a mode of delivery versus a teaching method. In this chapter Bates compares teaching delivery methods, defines which mode students need, and weighs in on the choice between face-to-face and online teaching.

    1. Independent Variable Manipulation

      Independent variable manipulation is the hallmark of experimental design.

    2. empirical and qualitative evidence suggests that students prefer to have writing feedback delivered electronically.

      This information about student and instructor preferences for submitting coursework online or in person provides the starting point in the argument for providing feedback to students electronically, rather than coming to class with a paper copy and receive handwritten notes on the paper copy.

    3. Writing proficiency is an essential learning outcome for undergraduate education as a whole and, specifically, in postsecondary psychology education. The American Psychological Association (APA, 2013) explicitly names effective writing as a goal in its guidelines for psychology majors,

      Effective writing is a core principle in education, emphasized by the most noted national psychological associations (APA; American Psychological Association). The following sections outline efforts to streamline the methods used instructor to student feedback for essays in a psychology class.

    1. M5 Successful Online Instruction

      Notes


      Basic Principles:


      View this from various perspectives (ID, Teacher, Student POV)


      • Communication with Students
      • Collaboration among students
      • High Expectations
      • Prompt Feedback
      • Active learning experiences
      • Respecting diversity

      structure of instruction

      • Organization
      • Syllabus facilitationinstructional materials *assessments
      • teaching and learning environments + tecvhnologies

      Teacher Roles

      • elaborating course content
      • supervising and moderating discussions
      • supervising indiv. and group projects.
      • grading assignments and providing feedbacks
      • answering all sorts of questions
      • helping students manage their study
      • motivating students Etc.

      Community of Learners

      Cultivate a community of learners and possible group of peers that they can rely on for feedback, sharing knowledge, critiques and fruitful interactions. Assessments would need to be criterion-based (rubric) and product-oriented. Environment has to be adaptable and technology-driven.

      Management

      Communication Very important, specially in fully online. You can create routines, correspondence time, and an open link for gathering around and meeting with the instructor.

      Assignments and grading They are useful to check in on progress. There is a debate on fewer vs. many. Have an expectation set in advance, like the use of rubrics. Provide examples or not?

      Reflection: For art classes a rubric would be good, but not examples. Examples can cause students to copy the example and you want to encourage them to do it well.

      Plagiarism: Teach students about copyright and fair use. Teach students how to cite and provide reference. Provide an institutional policy. Tracing = bad.

      Reflection: How big of a concern would plagiarism be in an art class?

      Review Other Elements in the textbook.

      reflection: Joshua might be fairly good with tech. We need to have some support for future instructors that might take over that class. Provide material for students and instructors on support.

    1. Gagne's nine events of instruction I am including this page for myself because it is a nice reference back to Gagne's nine events and it gives both an example of each of the events as well as a list of four essential principles. It also includes some of his book titles. rating 4/5

    1. This link is to a three-page PDF that describes Gagne's nine events of instruction, largely in in the form of a graphic. Text is minimized and descriptive text is color coded so it is easy to find underneath the graphic at the top. The layout is simple and easy to follow. A general description of Gagne's work is not part of this page. While this particular presentation does not have personal appeal to me, it is included here due to the quality of the page and because the presentation is more user friendly than most. Rating 4/5

    1. At the heart of good teaching with technology are three core components: content, pedagogy, and technology, plus the relationships among and between them. The interactions between and among the three components, playing out differently across diverse contexts, account for the wide variations seen in the extent and quality of educational technology integration

      Incorporating technology on its own will not be helpful to us when we are teaching. We must also base what tools we use around the content that we are teaching, our teaching methods and ability to differentiate a lesson, and the type of technology we are trying to incorporate. Technoology is useful when used correctly and wisely, so when we lesson plan, we must think about these before implementing our instruction.

    1. Students are entitled to a more educative and user-friendly assessment system. They deserve far more feedback -- and opportunities to use it -- as part of the local assessment process.

      Evaluate and reflect on your assessment systems. Do you have a system in the sense that it is longitudinal and recursive? How do you need to adjust your practices to ensure students get this feedback on their learning?

    2. Our job is to teach to the standards, not the test.

      What would it take to go an entire year thinking this way? What habits in planning do you need to address? How would your assignments change?

    3. Inside the Black Box: Raising Standards Through Classroom Assessment
    4. The point of assessment in education is to advance learning, not to merely audit absorption of facts.

      How do we need to change language among teachers and students to change perception? What kinds of practical habits can we adopt?

    1. There is no debate at this point among scientists that reading is a skill that needs to be explicitly taught by showing children the ways that sounds and letters correspond.
    2. But the science shows clearly that when reading instruction is organized around a defined progression of concepts about how speech is represented by print, kids become better readers. There is also widespread support in the research for the effectiveness of teacher-directed lessons as opposed to letting children discover key concepts about reading on their own.
    3. teacher-directed whole-class phonics lessons with small-group activities to meet the needs of children at different points in the process of learning to read.

    1. If students do not complete the courses they need to graduate, they can’t progress.

      The #retention perspective in Learning Analytics: learners succeed by completing courses. Can we think of learning success in other ways? Maybe through other forms of recognition than passing grades?

    1. The flexibility and social nature of how technology infuses other aspects of our lives is not captured by the model of Personalized Instruction, which focuses on the isolated individual’s personal path to a fixed end-point. To truly harness the power of modern technology, we need a new vision for educational technology (Enyedy, 2014: 16).

    1. Learning to complete a whole task involves 4 levels of instruction (preferably modeled):

      Effective instruction should engage students in all four levels of performance: the problem level, the task-level, the operation-level, and the action-level.

    2. First Principles of Instruction

      Click here to see more detailed description of the First Principles of Instruction.

    1. FIRST PRINCIPLES OF INSTRUCTION

      An Elaboration of the First Principles of Instruction.

    2. Much instructional practice concentratesprimarily on the demonstration phase and ig-nores the other phases in this cycle of learning.

      Yes, and also demonstration which is decontextualized, has not audience, no stakeholders...

    3. Many current instructional models suggest thatthe most effective learning products or environ-ments are those that are problem-centered andinvolve the student in four distinct phases oflearning: (a) activation of prior experience, (b)demonstration of skills, (c) application of skills,and (d) integration of these skills into real-worldactivities.

      (a) activation of prior experience (b)demonstration of skills (c) application of skills,and (d) integration of these skills into real-worldactivities

    4. Principle 1—Problem-centered: Learning ispromoted when learners are engaged in solvingreal-world problems.

      In my experience, this is a very powerful principle for learning.It can provide many variables that are not present in traditional learning environments:

                   * Authentic context
                   * Complex problems  
                   * Real stakeholders
                   * Authentic feedback from real stakeholders 
      

      Solving real-world problems can naturally lead to inter-disciplinary work and high levels of motivation if the student is allowed to pick a real world problem that is important for them.

    5. Five firstprinciples are elaborated: (a) Learning ispromoted when learners are engaged insolving real-world problems. (b) Learning ispromoted when existing knowledge isactivated as a foundation for new knowledge.(c) Learning is promoted when new knowledgeis demonstrated to the learner. (d) Learning ispromoted when new knowledge is applied bythe learner. (e) Learning is promoted whennew knowledge is integrated into the learner’sworld.
