Wakelet - Share Visually-Engaging Stories

Mon, 16 Dec 2019 00:00:00 +0000

What is a Wakelet?

Several months ago, I came across Wakelet. My first impression was that it is another social bookmarker because you can “bookmark anything you find online in two clicks.” But after some days working with it, I noticed it is more than that.

The reason for my changed awareness of Wakelet is its feature to create stories. Arranging bookmarks into “collections,” you can organize your bookmarks, adding text, and include images to get your narrative across. With Wakelet, you curate and share content not only in a meaningful but also in a visually-engaging way.

How do People use Wakelet?

I think the best way is to illustrate the possibilities and benefits of Wakelet is by showcasing some excellent examples. I have grouped my collected Wakelets, and to demonstrate the range of different options, I have always provided two instances for each category.

This is the first and prominent use of content curation, especially for education. @realUcyJoy is as an educational entrepreneur and advocate passionate about the use of education technology in Africa to improve learning. She shares a collection of 20 Digital skills for educators with us. Another very sophisticated design of a Wakelet resource page has @drbexl (Dr. Bex Lewis) created.

Portfolio

My name twin @FelixBaumgartner (I am not related to him) famous for his spectacular skydive uses Wakelet to promote himself and his adventurous projects. All collections on his homepage serve as material for media publications. Another showcasing page maintains Beth Tweddle @bethtweddlenews), a gymnastics Olympic medallist.

Raising awareness

The Rohingya Crisis @Rohingya uses Wakelet for political reasons to draw support to stop the genocide, ethnic cleansing and numerous crimes against the Rohingya. The Glasgow Centre for Population Health @theGCPH documents its conferences on providing leadership for action to tackle inequality and improve health via a series of tweeds, as can be seen by the example of its Glasgow’s Healthier Future Forum 20.

Philippe Schuler @Phil demonstrates his love for sports, drums, photography, nature, and travel with some astonishing photographs. Another example of this kind of usages gives Teijas ky @teijasky, one of the developers of Wakelet. He binds his amazing marine biology photos from the Galapagos Islands into a story of the history of the geological and biological processes of this archipelago.

Education

There are many examples of educational applications of Wakelet. Educational scenarios with Wakelet are so crucial for the developers that they dedicated a particular homepage for learning communities. There is a specialized guide for educators, translated into several languages providing tips and tricks. (Surprisingly, a guide in German is still missing.) Some example Wakes are Ancient Greek Philosophy for learning and The EdTech Toolbox - 2019 for teaching. See the blog of Kathleen Morris and Online Tools for teaching and learning for more learning activities and educational scenarios with Wakelets.

Figure 1: Six Use Cases for Wakelets

Wakelet and the SAMR model

Ruben Puentedura’s SAMR model exemplifies the meaningful integration of technology into teaching. Instead of using “tech for tech’s sake,” the SAMR model features a view inspired by social constructivism.¹

Substitution: Students read an article on Wakelet instead of in class.
Augmentation: Wakelet allows for multimodality by enabling users to embed images, videos, articles, and more.
Modification: Students curate information and resources about a specific topic on Wakelet and can share it widely via social media for feedback. Students critically analyze content and research to create an archive for discussion.
Redefinition: Students have access to real-time collaboration on multimodal content curation.

Wakelet works seamlessly with various apps

Figure 3: Ten different options to include content into a Wake.(Screenshot)

You can embed “Wakes” (= collection of items) into your web pages as I have done with the three referenced Wakelets above. (You can’t produce Wakes from Wakelet homepages.) There are three different formats to choose from and some design options how to present the Wakes.

The example above is an embedded Wake referring to other Wakes. Click on the different sections to get the referenced Wakes. You can also produce PDFs from your Wakes, but the PDFs are not interactive anymore. Look at this PDF example.

Storing content is just a two click action with its browser extensions, available for Firefox, Chrome, and Safari. Wakelet comes with mobile apps for Android (Google Play) and iOS (App Store) and it works also seamlessly with various tools like

Microsoft Teams
Microsoft OneNote — See: Better together: OneNote and Wakelet.
Google Drive — See: Google Drive Integration
Google Classroom
Remind
Fliprid — See: Flipgrid Integration

Wakelet is free and always will be

Wakelet also has a refined help system featuring many short but informative videos explaining the different highlights. Wakelet also comes with a specialized guide for educators in several languages. (Surprisingly, a guide in German is still missing.)

Furthermore, Wakelet is confidence-inspiring as it has sensible rules of usage and stringent privacy policy as well. And the best of it:

Wakelet is free and always will be. All of the features available now will remain free forever, even if we introduce premium plans in the future.

Feature requests

There are a two features I wish Wakelet would include. Both have to do with collaboration and sharing. I am not sure if my desires are in line with the developer’s strategy and plans. But anyway, here they are:

Genuine collaboration: At the moment, I can only invite contributors to add links but not to change or to delete the work I have done. So there is no real interworking in the sense of cross-functional cooperation possible. All the participants work in parallel but not as coordinated team players.
Community evaluation: Sharing links is okay but lacks quality control. I would like to have feedback from the community either as comments or as attached discussion fora. Tools like stars to appraise Wakes, as well as links, would also foster the community discussion and showcase the best collections. Make this a feature to turn on/turn off, so that people could decide if they want to draw critiques and spend time for discussions.

Update 2021-05-19: Both my feature requests are in the meanwhile realized.

Collaboration: The creator of a collection can offer a QR code, an alphanumeric code, or an URL. You can join a collection by one of these three options. You do not even have to log in! Watch this video. — Another (even newer) feature is “spaces”: With just several clicks, users can create a “space” to house content to be shared.

Community evaluation: Several icons (like 👍, 👏, 💯) are added so that visitors can give their “likes” to the collection in general or to individual links. Admittedly this is only a rudimentary evaluation, but you always can open up your wakelet for free collaboration so that other people can add additional links or comments.

Conclusion

Wakelet is not only a free sophisticated tool for content curation but also well-suited for visually-engaging presentations and story-telling. It has a steadily growing user base. Already some of the world’s most prominent organizations are using Wakelet.

Figure 4: Prominent organizations using Wakelet.

Wakelet encourages both the sharing of resources and their joint creation and curation of material. Still, in this area, some more features for cooperation would be desirable. A strict privacy policy combined with a well-engineered support page offering many short videos and helpful articles and a responsible team creates confidence for a long future of this product. And even if there comes a time where other similar products gain prominence, you can save your work via Wakelet’s export feature (JSON and PDF format) and change the web service presumably without too many troubles.

Announcing the R package coinsR

Fri, 02 Aug 2019 00:00:00 +0000

Update 2021-05-21: Because of some breaking changes in the Hugo site structure and management in the last three years, coinsR works at the moment only with individual pages.

This blog entry announces the R program coinsR to produce bibliographic metadata automatically for websites within the Hugo framework. The dominant use case at the moment is with the blogdown package.

In a previous blog entry I wrote about the advantages of providing bibliographic metadata for your web pages producing COinS. COinS is the abbreviation of Context Objects in Spans. It refers to a microformat standard to embed bibliographic metadata as HTML.

A COinS string includes HTML code for all the information necessary to cite a publication correctly. It works for every type of writing (books, papers, web pages). COinS embedded in your HTML pages help your blog readers or website visitors to cite your posts and pages correctly.

I wrote also a detailed tuorial how to produce COinS with the help of the free bibliographical research tool Zotero. But this is a quite complicated procedure with several steps. Besides, it works only for every page individually and not automatically for all blog entries of your website.

To produce COinS for every web page quickly was my motivation to write the R package coinsR.

Use cases of `coinsR` and its limitations

The package requires:

Hugo with the R package blogdown
Config file in the TOML format (config.toml)
Blog entries with YAML frontmatter

I plan for a future version to loosen the last two limitations and allow config.yaml and TOML frontmatter (but not for .json).

Update 2021-05-21: This plan is still relevant: I would like to loosen some restrictions and improve the user interface.

You can call coinsR via an RStudio Addin for every page individually. But you can also produce COinS automatically for all files under a specific directory.

Where to find `coinsR` and how to install it?

You can download the package from Github with

remotes::install_github('petzi53/coinsR', build_vignettes = TRUE)

I am trying to prepare coinsR as an R package distributed via the CRAN repository. But as I am still not very experienced in R programming, I am not sure if I will succeed.

You will find a detailed description in the help file and the vignette description of how to invoke the two functions coins_this() and coins_all().

Advantages of URL shortener

Tue, 23 Jul 2019 00:00:00 +0000

Citing and visiting web addresses with long URLs is sometimes complicated. Long URLs are particularly a hardness when there are no clickable links but only long strings printed on paper. This article suggests URL shortener to avoid the hurdle mentioned above.

What is a URL Shortener?¹

At first, we need to clarify what an “URL” is. “URL” stands for “Uniform Resource Locator,” and they’re a way of identifying the location of a file on the internet.

A URL is not the same as a domain name! Sometimes these both terms are confused and used interchangeably. But a domain name is just one part of a URL. The image below shows the difference:

Figure 1: Parts of an Uniform Resource Locator (URL)²

Use URL shortener for your references

Depending on the Content Management System (CMS) the website is using you can get very long URLs. There are three types of long URLs:

Long pretty URLs: These URLs consist of understandable text strings. Example: https://www.dbfk.de/media/docs/expertengruppen/pflegemanagement/DBfK-Handreichung-BAG-Pflegemanagement-Anwerbung-auslaendischer-Mitarbeiter_innen.pdf
Long ugly URLs: These URLs include randomly mixed characters, generated automatically by the CMS. Example: https://www.art.com/gallery/id--c23945/decorative-art-prints.htm?ui=6731D67F76A44083AD1B8F110C4FE301.
Long mixed URLs: These URLs contain understandable parts, but these sequences are directed to the CMS and not to humans. Examples are strings for the search engine: https://www.sfgate.com/search/?action=search&firstRequest=1&searchindex=solr&query=%22earthquake+san+francisco%22.

The solution for all these kinds of long URLs is the usage of URL shortener. There is a great variety of URL shortener available. But instead to use the automatic generated short URL (e.g., something like bit.ly/2GIYPa3) use the possibility to edit the URL with an appropriate and memorable word. Although these strings are often longer than the automatically generated short URL, they are much easier to type. Besides, you or other users can even memorize them (e.g., https://bit.ly/url-shortener).

As other users of the service also take memorizable short URLs, sometimes there may be a clash of URLs. If this happens, then you are not allowed to generate this specific URL. To prevent colliding URLs, I use a short prefix referring to me as the author or to the subject/project of the URL (e.g., https://bit.ly/pb-url-shortener).

Summary

You might be thinking that shortening your URL is an extra step, but URL shorteners are very beneficial:

Short URLs are more comfortable to share
Short URLs are essential if there is limited space (e.g., Twitter)
Short URLs are more visually appealing
Short URLs are memorized easier
Short URLs are more straightforward to type when there is only a paper reference
Short URL services can provide additional information such as the number of clicks
Short URLs can be adjusted if the original URL changes, so that users still have the correct links
Short URLs services allow you sometimes to create your brand and categories for your URLs. If they do not provide this service, you can use prefixes to get some rudimentary management for your URLs
Short URLs prevent line breakings (e.g., in emails) so that the user does not have to cut and paste to put the link together

But there is also a disadvantage of URL shortener:² They are often used by spammers to hide the URL destination. That way, unsuspecting people are more likely to click on them.

Wakelet

In addition to the following Wakelet, there is also a community edition on my Wakelet homepage where you can add relevant links.

Bibliographic Metadata for your web page

Wed, 19 Jun 2019 00:00:00 +0000

With Web 2.0, we see a radical change in scholarly communication. On the one hand, there is a growing need for researchers to be present on different web channels (blog, twitter, youtube, and much more). On the other hand, the more traditional ways of publications in high ranked peer review channels are still prevalent. It is difficult for researchers to meet this twofold challenge at the same time: After all the day has only 24 hours!

Double bind for ECRs

Figure 1: EURAXESS - Researchers in Motion is a unique pan-European initiative delivering information and support services to professional researchers.

Especially for young researchers (so-called Early Career Researchers, or ECRs¹ is this situation alarming and even existence-threatening. The find themselves in a double-bind: Should they more invest in traditional ways of career planning, or is it more promising to expand and foster their internet presence? I do not have a clear solution for myself. I think a transition period, the most secure strategy is to follow both paths.

ECRs have both the most to gain and the most to lose from being at the forefront of changes to scholarly communications [@eve_open_2014; @st._louis_open_2015].

COinS and Zotero

Figure 2: Zotero is a free, easy-to-use tool to help you collect, organize, cite, and share research.

The only way I can think of to meet both challenges is to maximize the efficiency of all career moves. One of my aims with this blog on Open Science Education is to talk about technology supported new ways for research and publication to fulfill both requirements.

With the following lines, I will show you how you can help your blog readers or website visitors to cite your posts and pages correctly and in way that they could count as a kind of publication.

My suggestion is

to use the free research tool Zotero
to produce a specific HTML code (COinS = Context Objects in Spans) and
inject this code into your web page.

COinS is a microformat standard to embed bibliographic metadata for Embedding in HTML. COinS include as HTML code all the information necessary to cite a publication correctly. It works for every type of publication (books, papers, web pages).

Figure 3: Zotero is designed to store, manage, and cite bibliographic references, such as books and articles. It is available for Mac, Windows, and Linux.

There are several possibilities to generate COinS, but I will focus on Zotero. I am not going into further details here, but I have prepared a tutorial with images from all the necessary steps to produce, embed, and download COinS.

References

There are different definitions for ECRs around, varying how many years after a Ph.D. are included. The period starts from 4 years and goes to in some institutions to 10 years. A more detailed description of different research profile descriptors has the European Research Commission (EURAXESS) ↩︎

Grammarly: A Case Study

Sun, 09 Jun 2019 00:00:00 +0000

In another post, I reported on my general experiences with Grammarly. I commented on different use cases, mainly with text pieces from my blog writing. By contrast, this post here focuses on a case study with a literary text piece from a novel.

I have taken the first 5,000 characters of a still unpublished German novel from a friend of mine. For an informed assessment, I am not just going to explain the different steps but will also provide the resulting text documents as attachments.

The different phases of my workflow

I ran the text passage through Google Translate and revised the text with Grammarly in two steps.

Figure 1: Screenshot of Grammarly alerts after Google Translate

Step 1: This is the German original text passage.

Step 2: The text after Google Translate (1 minute). In several passages, it is not understandable, and it feels awkward and clumsy.

Step 3: Working through the text with Grammarly uncritically, e.g., without reading and thinking, only following Grammarly’s alerts (2 minutes). Grammarly comes up with 19 alerts, almost half of them about spelling (5) and punctuation (4). Grammarly does not detect the incomprehensible sentences or clauses.

Step 4: Working through the text with Grammarly thoroughly, e.g., finding (with dict.cc) better suited vocabulary and changing sentence structures where appropriate to get a more correct and lively English (75 minutes).

I believe the final text is much better; even it is still imperfect and flawed. Please keep in mind that I am not an English native speaker.

The essential conclusion I want to draw after this experiment: The resulting text passage is in a quality I would have never achieved without the three tools I mentioned: Google Translate, dict.cc, and Grammarly].

Figure 2: Screenshot of Grammarly plans and pricing

Comments desired!

I would love to get comments from you:

If you are a German native speaker: What do you think about the quality of the result concerning the time needed?
If you are an English native speaker: Would you confirm that the Google Translator text is clumsy and in some passage not understandable? And first and foremost: Is the quality of the final version not all that bad and tolerable?
If you are neither a German nor English native speaker: What do you think about the final result respective to your English language skills? Would you think that Grammarly could improve your English?
And to all of you: Did the final text passage entice you to read more of the book? Should my friend invest 140 bucks to buy the premium version of Grammarly for one year and spend her leisure time to publish her novel?¹

Just a rough calculation: For 5,000 characters I needed all in all about 80 minutes. My friend’s English is better so that she would be possibly faster (and better) in the translation. But let us continue the calculation with 80 minutes. The novel has 450,000 characters = 90 x 5,000 character, i.e., 90 x 80 minutes = 8,100 minutes or 135 hours or 27 working days á 5 hours. ↩︎

Grammarly improves your writing

Fri, 07 Jun 2019 00:00:00 +0000

My story with Grammarly

This article reports on my experiences with the premium version of Grammarly, an AI-powered web service for grammar and spell checking. As this is going to be a very positive review, I feel the obligation to publicly disclose that I am not in any way affiliated with Grammarly Inc., the enterprise behind this product.

It was almost exactly one year ago in June 2018 when I learned the first time about Grammarly. I cannot remember anymore, why I stumbled over Grammarly. At first, I used it only with the free plan experimentally for some of my English writing on the web. I have to confess that I was very skeptical about the practical usefulness of this kind of app.

But after some tests, I was surprised about the quality of the suggestions. Grammarly was quite helpful as it gave me not only corrections for words spelled wrongly but also tips and ideas for a better style in English writing. At the same time, Grammarly told me not only how many improvements it has already suggested to me for a specific text passage, but also how many more suggestions would be in the premium version. Clearly enough, this was a sales gimmick, but a well-done one! I became curious about these other recommendations and signed finally up in August 2018 for the Premium version. At that time, it was still US$ 62,98 for a year, but in the meantime, the price has more than doubled (US$ 139,95) for the yearly subscription. I didn’t regret it!

Use cases illustrated by screenshots

Besides spell and grammar, Grammarly also helped me with style issues and even to find the right tone to address a particular audience. As a non-native speaker, it is difficult for me to judge any English improvements. But from reading much English literature, I’ve got the feeling that my English writing has improved tremendously.

I do not intend to write a tutorial for Grammarly, but I will give you some examples of use cases, illustrated by screenshots.

Use case 1: An already published article

I took a lengthy article (about 2.500 words), which I had published two years ago. I copied the markdown formatted text directly into the web interface of Grammarly. This article has a somewhat philosophical flavor so that technical concepts, which Grammarly has not in its dictionary, didn’t play a role. I had the text already cleaned up form spelling errors using RStudio’s spell checker. Nevertheless, Grammarly came up with more than 125 suggestions for improvements. I didn’t think that my English is so bad. How embarrassing!

When I inspected the text in detail, it turned out, that 19 suggested “improvements” weren’t useful, as they addressed quotes from English books by famous people like Michael Polanyi or Ludwig Wittgenstein. Another four recommendations related to markdown formatted text, where corrections would have resulted in syntax errors. But still there remained about 100 helpful tips! Statistically, Grammarly advised me about possible improvements every 25 words. I was shocked, and even a little depressed!

Grammarly suggests and explains a possible improvement

You see on the right top of the screenshot the number of alerts or warnings (= 120). Grammarly suggests finding a more common synonym for “emphatically” and explains with examples why it is maybe not the best choice. As all recommendations didn’t quite fit for my writing intention, I decided to delete this “overly complex” word without a substitution.

Use case 2: German text translated via Google Translate

I transcribed a German interview with Michael Rundel and ran the text through Google Translate. I believe, Google Translate has already overcome its start-up difficulties. Nowadays, I think, its translation is pretty good. But the writing must still be reviewed by a human.

As you can see in the image below, Grammarly recommended after an unpolished Google Translation from German to English a slightly better rate of improvements per word: 1892 words (bottom-left) with 104 tips (top-right) which accounts for one suggestion every 18 words.

Grammarly alerts in a machine-translated text

If you subtract the high number of 37 tips for punctuation issues (third line in the alerts list) – which partly are markdown formatting requirements and partly are differences between American and English punctuation rules – then the ratio improves to 1 tip for every 28 words. Admittedly this calculation is done under the caveat that after Google Translate, one has more sentences to restructure or to reformulate completely. But you can use Grammarly to implement these changes fairly quickly.

This calculation startles. Instead of struggling to formulate an English text from scratch and then to polish it with Grammarly, it appears to be more efficient – at least for me – to use another workflow: Writing my thoughts in a German paper -> than to translate it with Google Translate -> and finally using Grammarly to polish it.

Write the text in German

Translate it with Google Translate

Polish it with Grammarly

Publish it with Bookdown /Blogdown

But this reasoning is not entirely correct: The first version of the English text could already be done with Grammarly and would save one complete phase of the mentioned workflows. At least, I believe, this is valid for technical writing, where writing in English is not so complicated grammatically and therefore faster. But for publications in the Humanities, the workflow with Google Translate would be perhaps the better choice.

Use case 3: Writing English directly with Grammarly

To write text “live” in Grammarly has several advantages:

Grammarly gives you immediately a short explanation for every alert so that you can reformulate or restructure your document instantly.

Grammarly explains every current alert briefly and succinctly

Grammarly offers on-demand also longer clarifications and examples. So you can learn better writing during writing.

If required you can get from Grammarly a more profound explication with examples

Grammarly tutors you about the English language. This educational approach comes in handy when you notice that Grammarly often complains in similar situations. For instance, I didn’t know that there are different punctuation rules in American and British English. As I had written the lengthy text outside of Grammarly, I had to go through the whole article and change all occurrences of wrong punctuations one by one. If I had known these different rules, I would have to use the correct rules already in writing the draft version.

Grammarly offers on some subjects short tutorials

Grammarly supports different kinds of workflows: In the default configuration, Grammarly jumps automatically from one suggestion to the next. It is a good strategy for papers already written in English. But if you are writing directly within Grammarly, it is better to turn off this feature as it destroys the writing flow. Then you can select the recommendation you want to look at individually, and Grammarly jumps to the related text passage. A third option is to work on all tips concerning a specific category (e.g., spelling, grammar, punctuation, clarity, etc.) As you don’t have to jump from one type of problem to another one, the focus of one category of alerts speeds up the correction.

Working with Grammarly on alerts type ‘Punctuation’

Grammarly opens a window with synonyms when you double click on a word in your text.

Grammarly window to choose from a suggested synonym

Grammarly also offers recommendations to improve your writing style. The following screenshot presents my first try to begin this article. Grammarly analyzed it as a tedious text passage. This example demonstrates that Grammarly is far more than just a garden-variety of a spell or grammatic checker.

Screenshot of a Grammarly window with alert about a boring text passage

Grammarly varies its suggestions according to your writing goals. You can choose your intention, subject domain, target audience, your writing intention, your style (formal/informal), and even about the emotional flavor of your writing. Some of these features are still experimental, and I have to confess that I did not know when to choose what. I assume that my English is not good enough to use these advanced configurations.

Grammarly varies its alerts according to your chosen writing style

Grammarly can seamlessly be integrated via a browser plugin into types of web content (e.g., fora, web editing). But it seems to me that these possibilities are sparse. Yes, there is an add-in for Microsoft Word, but only for Windows. In WordPress, Grammarly does not work with the visual editor, you have instead to use the code editor. Likewise, you can’t use Grammarly with markdown files in RStudio or other text editors. But these shortages are not limitations as you can always write your book or article in the Grammarly cloud and then copy the text into your editor of choice. Grammarly stores your document in short time intervals, so you don’t have to worry to loose parts of your work. You can go back to unfinished articles at a later time and finish it for publication.

My personal desktop in Grammarly

I prefer to work with the browser extension, as it always presents the same user interface. Besides, it unleashes the full power of Grammarly. All screenshots in this post show the Grammarly editor in the browser, Google Chrome, in my case. But there are also plugins for Firefox, Safari, and Edge. All these browser extensions are free, and you can use Grammarly with limited functionality at no charge as well.

Other similar products

Finally, I should add that during the research of this article, I noticed that there are a couple of web services with related functionality available. The high number of recent articles about grammar apps insinuates a big market for this kind of service:

Wrapping up

All in all, I’m delighted with Grammarly. In my opinion, it is a beneficial tool for the non-native writer. It improves your writing for the web (e.g., posting in blogs or commenting in fora) but also for printed papers and books. It has many cute and even some outstanding features. Even with Grammarly, I am still not wholly comfortable to write in English, but at least I am stressed about it anymore.

I do not claim that Grammarly is the best product, as I do not know the other apps and have therefore no comparison. But in most of the reviews mentioned above, Grammarly is top ranked. It is undoubtedly the app with the biggest user base (over 10 Mio.).

Last, but not least, I would like to add that Grammarly is not idiot-proof. You have to make your choices, looking up other dictionaries to find better wording. (I am happy using all the time dict.cc). You have to be aware that even if Grammarly is AI driven, it does not understand your writing in the human sense. If you are writing a dumb and meaningless article, Grammarly cannot improve your reasoning and arguments. I noticed, for instance, that Grammarly sometimes had overlooked a missing word, an error a human would immediately see. And sometimes Grammarly is wrong with its suggestions as the last screenshot demonstrates. But these rare cases are easy to judge and correct.

Grammarly is not idiot-proof. Your own intelligent judgement is still required.
