The seventh edition of the Publication Manual of the American Psychological Association streamlines the process of creating references in APA Style. It is now easier and more straightforward to create references for all works and to accurately and consistently attribute sources. Join members of the APA Style team as they provide an in-depth look at the simplified reference system by describing the rationale behind it, how to format references using it, and the ways in which references are easier to create because of it. The webinar will then answer one of the most frequently asked Style questions: how to cite a work found online. The APA Style experts will use real-life examples to walk through the process of creating references for a variety of common webpages and websites, including ones with missing or hard-to-locate information, found via a database, and needing electronic source information (DOIs, URLs, and retrieval dates).
Gardner now teaches at the Harvard Graduate School of Education. He is the author of numerous books on intelligence and creativity. His new book ”The App Generation,” co-authored with Katie Davis, explains how life for young people today is different than before the dawn of the digital age, and will be published on Oct. 22 by Yale University Press.
Gardner’s theory initially listed seven intelligences which work together: linguistic, logical-mathematical, musical, bodily-kinesthetic, spatial, interpersonal and intrapersonal; he later added an eighth, naturalist intelligence and says there may be a few more.
Excerpts from the blog entries under the article
The idea that multiple intelligences and learning styles have become interrelated is so true. Learning about all the different types of intelligences and learning, it can be hard to keep them all straight. This article was helpful in pointing out the differences. Educators should be aware of these differences, so that they might be able to better teach their students.
– how how human capacities are represented in the brain,
– a number of relatively independent mental faculties
– a number of relatively autonomous computers—[that compute] … information
A strong intelligence:
– an area where the person has considerable computational power
– the power of the mental computer, the intelligence, that acts upon that sensory information, once picked up
So “learning” = us[ing … (different) cognitive faculties?
Q1: Is that ok to assume and say?
Q2: What of “dimensions” – cognitive processing (higher order thinking) and knowledge (concrete to abstract) and sense of self, or affect[ive]?
– Individualize your teaching
– Pluralize your teaching. Teach important materials in several ways, …reach students who learn in different ways… [present] materials in various ways
Bibliographical data analysis with Zotero and nVivo
Bibliographic Analysis for Graduate Students, EDAD 518, Fri/Sat, May 15/16, 2020
This session will not be about qualitative research (QR) only, but rather about a modern 21st century approach toward the analysis of your literature review in Chapter 2.
However, the computational approach toward qualitative research is not much different than computational approach for your quantitative research; you need to be versed in each of them, thus familiarity with nVivo for qualitative research and with SPSS for quantitative research should be pursued by any doctoral student.
Please use this link to install nVivo on your computer. Even if we were not in a quarantine and you would have been able to use the licensed nVivo software on campus, for convenience (working on your dissertation from home), most probably, you would have used the shareware. Shareware is fully functional on your computer for 14 days, so calculate the time you will be using it and mind the date of installation and your consequent work.
For the purpose of this workshop, please install nVivo on your computer early morning on Saturday, May 16, so we can work together on nVivo during the day and you can continue using the software for the next two weeks.
Please familiarize yourself with the two articles assigned in the EDAD 815 D2L course content “Practice Research Articles“ :
Brosky, D. (2011). Micropolitics in the School: Teacher Leaders’ Use of Political Skill and Influence Tactics. International Journal of Educational Leadership Preparation, 6(1). https://eric.ed.gov/?id=EJ972880
whereas the snapshots are replaced with snapshots from nVivol, version 12, which we will be using in our course and for our dissertations.
Concept of bibliographic data
Bibliographic Data is an organized collection of references to publish in literature that includes journals, magazine articles, newspaper articles, conference proceedings, reports, government and legal publications. The bibliographical data is important for writing the literature review of a research. This data is usually saved and organized in databases like Mendeley or Endnote. Nvivo provides the option to import bibliographical data from these databases directly. One can import End Note library or Mendeley library into Nvivo. Similar to interview transcripts, one can represent and analyze bibliographical data using Nvivo. To start with bibliographical data representation, this article previews the processing of literature review in Nvivo.
Importing bibliographical data
Bibliographic Data is imported using Mendeley, Endnote and other such databases or applications that are supported with Nvivo. Bibliographical data here refers to material in the form of articles, journals or conference proceedings. Common factors among all of these data are the author’s name and year of publication. Therefore, Nvivo helps to import and arrange these data with their titles as author’s name and year of publication. The process of importing bibliographical data is presented in the figures below.

Coding strategies for literature review
Coding is a process of identifying important parts or patterns in the sources and organizing them in theme node. Sources in case of literature review include material in the form of PDF. That means literature review in Nvivo requires grouping of information from PDF files in the forms of theme nodes. Nodes directly do not create content for literature review, they present ideas simply to help in framing a literature review. Nodes can be created on the basis of theme of the study, results of the study, major findings of the study or any other important information of the study. After creating nodes, code the information of each of the articles into its respective codes.
Nvivo allows coding the articles for preparing a literature review. Articles have tremendous amount of text and information in the forms of graphs, more importantly, articles are in the format of PDF. Since Nvivo does not allow editing PDF files, apply manual coding in case of literature review. There are two strategies of coding articles in Nvivo.
Code the text of PDF files into a new Node.
Code the text of PDF file into an existing Node. The procedure of manual coding in literature review is similar to interview transcripts.
The Case Nodes of articles are created as per the author name or year of the publication.
For example: Create a case node with the name of that author and attach all articles in case of multiple articles of same Author in a row with different information. For instance in figure below, five articles of same author’s name, i.e., Mr. Toppings have been selected together to group in a case Node. Prepare case nodes like this then effortlessly search information based on different author’s opinion for writing empirical review in the literature.
Nvivo questions for literature review
Apart from the coding on themes, evidences, authors or opinions in different articles, run different queries based on the aim of the study. Nvivo contains different types of search tools that helps to find information in and across different articles. With the purpose of literature review, this article presents a brief overview of word frequency search, text search, and coding query in Nvivo.
Word frequency in Nvivo allows searching for different words in the articles. In case of literature review, use word frequency to search for a word. This will help to find what different author has stated about the word in the article. Run word frequency on all types of sources and limit the number of words which are not useful to write the literature.
For example, run the command of word frequency with the limit of 100 most frequent words . This will help in assessing if any of these words remotely provide any new information for the literature (figure below).
Text search is more elaborative tool then word frequency search in Nvivo. It allows Nvivo to search for a particular phrase or expression in the articles. Also, Nvivo gives the opportunity to make a node out of text search if a particular word, phrase or expression is found useful for literature.
For example: conduct a text search query to find a word “Scaffolding” in the articles. In this case Nvivo will provide all the words, phrases and expression slightly related to this word across all the articles (Figure 8 & 9). The difference between test search and word frequency lies in generating texts, sentences and phrases in the latter related to the queried word.
Apart from text search and word frequency search Nvivo also provides the option of coding query. Coding query helps in literature review to know the intersection between two Nodes. As mentioned previously, nodes contains the information from the articles. Furthermore it is also possible that two nodes contain similar set of information. Therefore, coding query helps to condense this information in the form of two way table which represents the intersection between selected nodes.
For example, in below figure, researcher have search the intersection between three nodes namely, academics, psychological and social on the basis of three attributes namely qantitative, qualitative and mixed research. This coding theory is performed to know which of the selected themes nodes have all types of attributes. Like, Coding Matrix in figure below shows that academic have all three types of attributes that is research (quantitative, qualitative and mixed). Where psychological has only two types of attributes research (quantitative and mixed).
In this way, Coding query helps researchers to generate intersection between two or more theme nodes. This also simplifies the pattern of qualitative data to write literature.
Please do not hesitate to contact me with questions, suggestions before, during or after our workshop and about ANY questions and suggestions you may have about your Chapter 2 and, particularly about your literature review:
Freire’s pedagogical concepts, such as problem posing, dialogue, praxis, conscientiazation and the politics of education, were devel-oped in a pre-Internet era. His work in popular education was deeply interpersonal and involved spending significant time in a community becoming familiar with the culture, linguistic patterns, and lifestyle of the people before ever embarking on teaching.
struggles to employ a critical pedagogy in the increasingly assessment-oriented, outcomes-based environment
While designed to make teaching in the online environment more efficient, these systems confront the critical pedagogue with challenges to create a teaching-learning environment that promotes critical reflection not only on the content of a course but on the very way in which content is delivered.
teaching in cyberspace requires a different teaching paradigm altogether
p. 170 Feenberg (2009) developed the Critical Theory of Technology (CTT),
p. 171 As outlined by CTT, technology creates a cyber culture that redefines human identity and the meaning and means of human interaction (Gomez, 2009). When viewed through this lens, online education is not simply another tool for the promotion of learning, but rather an all-encompassing environment managing and controlling access to information, structuring relationships, and redefining individual identities.
p. 171 While masquerading as efforts to enhance student learning, these industries are clearly profit-oriented. Knowledge has become a commodity, students have become consumers, faculty have become content providers, and schools operate as businesses
p. 172 Like Feenberg (2009), Freire would be concerned with the values and principles embedded in the technology of online learning, as well as the cyber culture it has created.
p. 173 Schools did not venture into online learning because they thought it was a better way to teach, but rather because they saw it as a way to reach unreached student populations with the promise of off-site educational offerings. Only later was attention given to developing online pedagogies.
Whereas education in the United States was originally viewed as a way to prepare students for effective citizenship, now it is seen as a way to develop loyal and capable employees of their corporate overlords
p. 174 A second area of concern is the banking nature of the LMSs. One of the underlying assumptions of an LMS like Blackboard™, Moodle™, or Brightspace™ is that the online platform is a repository of resources for teaching and learning.
Freire vehemently rejected this banking approach to education because it did not recognize or encourage the student’s creative, exploratory, and critical abilities. In the banking model the teacher is regarded as the holder and transmitter of knowledge, which is then imparted to the student. The banking model assumes the student is an empty vessel and does not value or recognize the student’s experiential and cultural knowledge
By contrast Freire argued for a problem-posing, constructivist approach that invites students to critically engage their world and one another. In the critical classroom, the student at times takes on the role of teacher and the teacher becomes a learner, inviting a sharing of power and mutual learning. While this approach can be carried out to an extent online, the LMS is set up to be the primary source of information in a course, and the teacher is assigned as the expert designer of the learning experience, thus limiting the constructivist nature and mutuality of the learning process.
p. 175 A third area of concern is the limited access to online learning to large sectors of society. While e-learning advocates tout the greater access to learning provided by online learning (Goral, 2013; Kashi & Conway, 2010), the digital divide is a reality impacting millions of students.
p. 176 A final area of concern is the disembodied nature of the online learning process. One of the major attractions of online learning to potential students is the freedom from having to be in a classroom in a particular time or place.
p. 177 Embodied learning means students must not only engage the cognitive dimension (thinking and reflection), but also partake in concrete action. This action in reflection, and reflection in action, referred to as praxis, involves acting on and in the world as one is seeking to learn about and transform the world.
To limit education to the transmission and reception of text-based knowledge without action undermines the entire learning process (Escobar et al., 1994). Freire believed dialogue begins not with what the teacher professes to know, but with the student’s experience and knowledge.
p. 179 For Freire, the building of a learning community is essential to creating meaningful dialogue; this is also true for those who seek to teach effectively online. Palloff and Pratt (2007) contend that all online teaching must begin with building community and stress that a carefully constructed online learning community provides a space for students to test ideas, get feedback, and create a collaborative learning experience.
For Freire, learning was a social and democratic event where authoritarianism and control of the learning process are minimized. “reading the world,” or conscientization, that is, understanding the larger political context in which experience occurs and knowledge is situated. In the current era of Facebook, Twitter, instant message, and other social media, in-depth discussion and analysis is often absent in favor of brief, often innocuous statements and personal opinions. Through online academic databases, students have easy access to far more sources of information than previous generations. Furthermore, search engines like Google, Yahoo, and the like bring students in contact with remote sources, organizations, and individuals instantly.
p. 180 the challenge is not only the accessing of information, but also encouraging students to become discerning purveyors of information—to develop “critical digital literacy,” the capacity to effectively and critically navigate the databases and myriads of potential sources (Poore, 2011, p. 15)
Algorithmic test proctoring’s settings have discriminatory consequences across multiple identities and serious privacy implications.
While racist technology calibrated for white skin isn’t new (everything from photography to soap dispensers do this), we see it deployed through face detection and facial recognition used by algorithmic proctoring systems.
As Os Keyes has demonstrated, facial recognition has a terrible history with gender. This means that a software asking students to verify their identity is compromising for students who identify as trans, non-binary, or express their gender in ways counter to cis/heteronormativity.
These features and settings create a system of asymmetric surveillance and lack of accountability, things which have always created a risk for abuse and sexual harassment. Technologies like these have a long history of being abused, largely by heterosexual men at the expense of women’s bodies, privacy, and dignity.
my note: I am repeating this for years
Sean Michael Morris and Jesse Stommel’s ongoing critique of Turnitin, a plagiarism detection software, outlines exactly how this logic operates in ed-tech and higher education: 1) don’t trust students, 2) surveil them, 3) ignore the complexity of writing and citation, and 4) monetize the data.
Cheating is not a technological problem, but a social and pedagogical problem.
Our habit of believing that technology will solve pedagogical problems is endemic to narratives produced by the ed-tech community and, as Audrey Watters writes, is tied to the Silicon Valley culture that often funds it. Scholars have been dismantling the narrative of technological solutionism and neutrality for some time now. In her book “Algorithms of Oppression,” Safiya Umoja Noble demonstrates how the algorithms that are responsible for Google Search amplify and “reinforce oppressive social relationships and enact new modes of racial profiling.”
Anna Lauren Hoffmann, who coined the term “data violence” to describe the impact harmful technological systems have on people and how these systems retain the appearance of objectivity despite the disproportionate harm they inflict on marginalized communities.
Higher education is deeply complicit in the eugenics movement. Nazism borrowed many of its ideas about racial purity from the American school of eugenics, and universities were instrumental in supporting eugenics research by publishing copious literature on it, establishing endowed professorships, institutes, and scholarly societies that spearheaded eugenic research and propaganda.
\Asking for a “friend,” does anyone know if on a Zoom call whether the host can tell if you’ve navigated to another window – i.e., multi-tasking? I’ve heard of teachers threatening students with this capability.
My note: From a pedagogical point of view, the bigger question is: does one (instructor) need to “big brother” students’ activities, in this case multi-tasking on another window.
Blast from the past: http://blog.stcloudstate.edu/ims/2017/04/03/use-of-laptops-in-the-classroom/
Here is the collection of opinions regarding a similar issue 15 years ago: do we have to let students use Internet-connected laptops in the class room and 5 years ago: can we let students use smart phones in the classroom.
The opinion i liked most and side with it: if we (the instructors) are not able to create arresting content and class presence, we should not blame students for straying away from our activities. It does not matter how much control Zoom will give us to “big brother” students, it is up to our teaching, not to the technology to keep students learning

Currently there are limited ways to connect 3D VR environments to physical objects in the real-world whilst simultaneously conducting communication and collaboration between remote users. Within the context of a solar power plant, the performance metrics of the site are invaluable for environmental engineers who are remotely located. Often two or more remotely located engineers need to communicate and collaborate on solving a problem. If a solar panel component is damaged, the repair often needs to be undertaken on-site thereby incurring additional expenses. This triage of communication is known as inter-cognitive communication and intra-cognitive communication: inter-cognitive communication where information transfer occurs between two cognitive entities with different cognitive capabilities (e.g., between a human and an artificially cognitive system); intra-cognitive communication where information transfer occurs between two cognitive entities with equivalent cognitive capabilities (e.g., between two humans) [Baranyi and Csapo, 2010]. Currently, non-VR solutions offer a comprehensive analysis of solar plant data. A regular PC with a monitor currently have advantages over 3D VR. For example, sensors can be monitored using dedicated software such as EPEVER or via a web browser; as exemplified by the comprehensive service provided by Elseta. But when multiple users are able to collaborate remotely within a three-dimensional virtual simulation, the opportunities for communication, training and academic education will be profound.

Virtual Reality Technologies for Learning Designers
Virtual Reality (VR) is a computer-generated experience that simulates presence in real or imagined environments (Kerrebrock, Brengman, & Willems, 2017). VR promotes contextualized learning, authentic experiences, critical thinking, and problem-solving opportunities. Despite the great potential and popularity of this technology, the latest two installations of the Educause Horizon Report (2018, 2019) have argued that VR remains “elusive” in terms of mainstream adoption. The reasons are varied, including the expense and the lack of empirical evidence for its effectiveness in education. More importantly, examples of successful VR implementations for those instructors who lack technical skills are still scarce. Margherita Berti will discuss a range of easy-to-use educational VR tools and examples of VR-based activity examples and the learning theories and instructional design principles utilized for their development.
Margherita Berti is a doctoral candidate in Second Language Acquisition and Teaching (SLAT) and Educational Technology at the University of Arizona. Her research specialization resides at the intersection of virtual reality, the teaching of culture, and curriculum and content development for foreign language education.
There is a barrier between an author and readers of his/her books. The author’s journey ends, and the reader’s begins.

Until now, technology that readily identifies everyone based on his or her face has been taboo because of its radical erosion of privacy. Tech companies capable of releasing such a tool have refrained from doing so; in 2011, Google’s chairman at the time said it was the one technology the company had held back because it could be used “in a very bad way.” Some large cities, including San Francisco, have barred police from using facial
But without public scrutiny, more than 600 law enforcement agencies have started using Clearview in the past year, according to the company, which declined to provide a list. recognition technology.
Facial recognition technology has always been controversial. It makes people nervous about Big Brother. It has a tendency to deliver false matches for certain groups, like people of color. And some facial recognition products used by the police — including Clearview’s — haven’t been vetted by independent experts.
Clearview deployed current and former Republican officials to approach police forces, offering free trials and annual licenses for as little as $2,000. Mr. Schwartz tapped his political connections to help make government officials aware of the tool, according to Mr. Ton-That.
“We have no data to suggest this tool is accurate,” said Clare Garvie, a researcher at Georgetown University’s Center on Privacy and Technology, who has studied the government’s use of facial recognition. “The larger the database, the larger the risk of misidentification because of the doppelgänger effect. They’re talking about a massive database of random people they’ve found on the internet.”
Part of the problem stems from a lack of oversight. There has been no real public input into adoption of Clearview’s software, and the company’s ability to safeguard data hasn’t been tested in practice. Clearview itself remained highly secretive until late 2019.
The software also appears to explicitly violate policies at Facebook and elsewhere against collecting users’ images en masse.
while there’s underlying code that could theoretically be used for augmented reality glasses that could identify people on the street, Ton-That said there were no plans for such a design.
facial recognition bans are the wrong way to fight against modern surveillance. Focusing on one particular identification method misconstrues the nature of the surveillance society we’re in the process of building. Ubiquitous mass surveillance is increasingly the norm. In countries like China, a surveillance infrastructure is being built by the government for social control. In countries like the United States, it’s being built by corporations in order to influence our buying behavior, and is incidentally used by the government.
People can be identified at a distance by their heart beat or by their gait, using a laser-based system. Cameras are so good that they can read fingerprints and irispatterns from meters away. And even without any of these technologies, we can always be identified because our smartphones broadcast unique numbers called MAC addresses.
The data broker industry is almost entirely unregulated; there’s only one law — passed in Vermont in 2018 — that requires data brokers to register and explain in broad terms what kind of data they collect.
