    1. Phenomenal consciousness is only seemingly private because in order to measure it one needs to be in the appropriate cognitive frame of reference. It is not a simple transformation to change from a third-person cognitive frame of reference to the first-person frame, but in principle it can be done, and hence phenomenal consciousness isn’t private anymore.

    1. Recent work has revealed several new and significant aspects of the dynamics of theory change. First, statistical information, information about the probabilistic contingencies between events, plays a particularly important role in theory-formation both in science and in childhood. In the last fifteen years we’ve discovered the power of early statistical learning.

      The data of the past is congruent with the current psychological trends that face the education system of today. Developmentalists have charted how children construct and revise intuitive theories. In turn, a variety of theories have developed because of the greater use of statistical information that supports probabilistic contingencies that help to better inform us of causal models and their distinctive cognitive functions. These studies investigate the physical, psychological, and social domains. In the case of intuitive psychology, or "theory of mind," developmentalism has traced a progression from an early understanding of emotion and action to an understanding of intentions and simple aspects of perception, to an understanding of knowledge vs. ignorance, and finally to a representational and then an interpretive theory of mind.

      The mechanisms by which life evolved—from chemical beginnings to cognizing human beings—are central to understanding the psychological basis of learning. We are the product of an evolutionary process and it is the mechanisms inherent in this process that offer the most probable explanations to how we think and learn.

    1. Research is needed to determine the situations in which the redundancy principle does not hold

      p. 144-145

      The authors describe limits to the research (circa 2016) as follows: 1. Kinds of learners, 2. kinds of material, and 3. kinds of presentation methods. Each of these situations present interesting possibilities for research related to the use of closed captions used by first-year law students while watching course-related videos.

      When considering how "kinds of learners" might be relevant, the authors ask how redundant on-screen text might hurt or help non-native speakers of a language or learners with very low prior knowledge. It is probably reasonable to consider first-year law students as having "very low prior knowledge". Is there any sense in which those same students could be understand as having overlapping characteristics with TBD

    2. Principle 2: Consider Adding On‐Screen Text to Narration in Special Situations

      p. 139-141

      Clark and Mayer describe a key exception to the first principle they describe. One of the special situations they describe consists of when a learner must "exert greater cognitive effort to comprehend spoken text rather than printed text" (p. 140). This could be when the verbal material is complex and challenging, such as when learners are learning another language or when terminology is challenging such as might be encountered in scientific, technical, or legal(?) domains (p. 141).

      [P]rinting unfamiliar technical terms on the screen may actually reduce cognitive processing because the learner does not need to grapple with decoding the spoken words.

      However, it may be necessary to ensure that video is slow-paced or learner-controlled under circumstances where both audio narration and on-screen text are provided. Mayer, Lee, and Peebles (2014) found that when video is fast-paced, redundant text can cause cognitive overload, even when learners are non-native speakers.

    3. boundary conditions.

      p. 131-132

      Clark and Mayer provide a brief summary of the boundary conditions, the situations in which learners benefit from the use redundant on-screen text. These situations include adding printed text when 1) there are no graphics, 2) the presentation rate of the on-screen text is slow or learner-controlled, 3) the narration includes technical or unfamiliar words, and the 3) on-screen text is shorter than the audio narration.

      The first three conditions described bear some similarity to closed caption use by students in legal education watching class lecture videos, especially students in first-year courses. Typically, the students are viewing videos with very few detailed graphics, they have control over the speed, pause, review, and advance features of the video player, and the narration provides numerous legal terms.

      Although closed captions are intended for hard of hearing and deaf viewers, they may have some benefits for other learners if the boundary conditions described by the authors turn out to be true. Dello Stritto and Linder (2017) shared findings from a large survey of post-secondary students reporting that a range of students found closed captions to be helpful.

    4. graphics using words in both on‐screen text and audio narration in which the audio repeats the text. We call this technique redundant on‐screen text because the printed text (on‐screen text) is redundant with the spoken text (narration or audio).

      Clark and Mayer provide a definition of redundant: Graphics accompanied by words in both on-screen text and audio narration in which that text is repeated. p. 131

      The authors go on to provide guidance about concurrent graphics, audio, and on-screen text. Based upon the research that they summarize in Chapter Seven, they advise instructors not to add printed text to an on screen graphic.

    1. One last resource for augmenting our minds can be found in other people’s minds. We are fundamentally social creatures, oriented toward thinking with others. Problems arise when we do our thinking alone — for example, the well-documented phenomenon of confirmation bias, which leads us to preferentially attend to information that supports the beliefs we already hold. According to the argumentative theory of reasoning, advanced by the cognitive scientists Hugo Mercier and Dan Sperber, this bias is accentuated when we reason in solitude. Humans’ evolved faculty for reasoning is not aimed at arriving at objective truth, Mercier and Sperber point out; it is aimed at defending our arguments and scrutinizing others’. It makes sense, they write, “for a cognitive mechanism aimed at justifying oneself and convincing others to be biased and lazy. The failures of the solitary reasoner follow from the use of reason in an ‘abnormal’ context’” — that is, a nonsocial one. Vigorous debates, engaged with an open mind, are the solution. “When people who disagree but have a common interest in finding the truth or the solution to a problem exchange arguments with each other, the best idea tends to win,” they write, citing evidence from studies of students, forecasters and jury members.

      Thinking in solitary can increase one's susceptibility to confirmation bias. Thinking in groups can mitigate this.

      How might keeping one's notes in public potentially help fight against these cognitive biases?

      Is having a "conversation in the margins" with an author using annotation tools like Hypothes.is a way to help mitigate this sort of cognitive bias?

      At the far end of the spectrum how do we prevent this social thinking from becoming groupthink, or the practice of thinking or making decisions as a group in a way that discourages creativity or individual responsibility?

    1. The Attack on "Critical Race Theory": What's Going on?

      https://www.youtube.com/watch?v=P35YrabkpGk

      Lately, a lot of people have been very upset about “critical race theory.” Back in September 2020, the former president directed federal agencies to cut funding for training programs that refer to “white privilege” or “critical race theory, declaring such programs “un-American propaganda” and “a sickness that cannot be allowed to continue.” In the last few months, at least eight states have passed legislation banning the teaching of CRT in schools and some 20 more have similar bills in the pipeline or plans to introduce them. What’s going on?

      Join us for a conversation that situates the current battle about “critical race theory” in the context of a much longer war over the relationship between our racial present and racial past, and the role of culture, institutions, laws, policies and “systems” in shaping both. As members of families and communities, as adults in the lives of the children who will have to live with the consequences of these struggles, how do we understand what's at stake and how we can usefully weigh in?

      Hosts: Melissa Giraud & Andrew Grant-Thomas

      Guests: Shee Covarrubias, Kerry-Ann Escayg,

      Some core ideas of critical race theory:

      • racial realism
        • racism is normal
      • interest convergence
        • racial equity only occurs when white self interest is being considered (Brown v. Board of Education as an example to portray US in a better light with respect to the Cold War)
      • Whiteness as property
        • Cheryl Harris' work
        • White people have privilege in the law
        • myth of meritocracy
      • Intersectionality

      People would rather be spoon fed rather than do the work themselves. Sadly this is being encouraged in the media.

      • Response video of threat, intimidation, emotional blackmail by local sheriff's department.
      • Intent versus impact - the superintendent may not have had a bad intent when providing an apology, but the impact was painful

      It's not really a battle about or against CRT, it's an attempt to further whitewash American history. (synopsis of SC)

    2. Finally, the utility of video lessons can be maximized by matching modality to content. By using both the audio/verbal channel and the visual/pictorial channel to convey new infor-mation, and by fitting the particular type of information to the most appropriate channel, instructors can enhance the germane cognitive load of a learning experience.

      matching modality to content. So if you want to talk about history, or a book, or just some reflection, it makes less sense to do it over video, but if you want to talk about art history maybe you want to have a video component or be primarily video

    3. Weeding, or the elimination of interesting but extraneous information that does not contribute to the learning goal, can provide further benefits. For example, music, complex back-grounds, or extra features within an animation require the learner to judge whether he or she should be paying attention to them, which increases extraneous load and can reduce learn-ing.

      Weeding + definition, removing flash and bells and whistles that might cause the student to be distracted

    4. The benefits of signaling are complemented by segmenting, or the chunking of information in a video lesson. Segmenting allows learners to engage with small pieces of new information and gives them control over the flow of new information.

      Segmenting or chunking

    5. Signaling, which is also known as cueing (deKoning et al., 2009), is the use of on-screen text or symbols to highlight important information. For example, signaling may be provided by the appearance of two or three key words (Mayer and John-son, 2008; Ibrahim et al., 2012), a change in color or contrast (deKoning et al., 2009), or a symbol that draws attention to a region of a screen (e.g., an arrow; deKoning et al., 2009).

      Signaling definition + examples

    6. The third component of a learning experience is extraneous load, which is cognitive effort that does not help the learner toward the desired learning outcome.

      extraneous load, the fiddling with technology, the finding new content to read, the poorly connected information, etc.

    7. The first of these is intrinsic load, which is inherent to the subject under study and is determined in part by the degrees of connec-tivity within the subject

      how difficult is a concept to understand, word pairing is less difficult than grammar rules.

    8. he second component of any learning experience is germane load, which is the level of cognitive activity necessary to reach the desired learning outcome—for example, to make the comparisons, do the analysis, and elucidate the steps necessary to master the lesson.

      the level of cognitive activity needed to learn the learning outcome (memorize a few words), define terms, recall a history event, draw something.

    9. This processing is a prerequisite for encoding into long-term memory, which has virtually unlimited capacity. Because working memory is very limited, the learner must be selective about what information from sensory mem-ory to pay attention to during the learning process, an observa-tion that has important implications for creating educational materials
    10. Cognitive load theory, initially articulated by Sweller (1988, 1989, 1994), suggests that memory has several components. Sensory memory is tran-sient, collecting information from the environment. Information from sensory memory may be selected for temporary storage and processing in working memory,

    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
