uHandy Mobile Microscope Duet review

Okay, I have not had this much fun since I got my first microscope when I was 10! I have always loved the microscopic world, and even conducted research on blood cells for a pharmaceutical company for my senior project. 

During the project, I had to remove blood from various animals (rat, rabbit, dog), spin the pipettes in a centrifuge, smear the blood on slides, and manually record the number of different types of white blood cells using an electron microscope. It really is true that the hands-on projects are the ones we remember the most! (I found a video of the type of manual counter I had to use on YouTube!)

If students do not have a microscope at home or limited access to one at school, they may never have the chance to explore the microscopic world in depth. This love could lead students on a career path they never thought they might take.

uHandy ask me to review their Mobile Microscope Duet and, after taking a look at it online, I readily agreed to test it out! I could not wait for it to arrive! (And they have even included a promo code for me to give out for a teacher discount!)

When I first opened the box, I was impressed by the number of items included and the well-written and illustrated user guide that had me up and running quickly! The first step was to install the uHandy app for iOS or Android. The app allows students to capture items as images or videos, adjust focusing, and switch between the Low-Mag and High-Mag lenses.


Low-Mag lens attached and three samples to try






My first experiment was to clip the Low-Mag (10x-300x) lens onto the back camera of my iPad Mini and attach a sample sticker of a down feather to the sample cap of the Lo-Mag lens.



The Sample Cap with the sample.





















The result was impressive as you can see below!

I then took the plastic cover off of the sample cap so I could view a sample that was irregular. I picked a coin to view.

Next came experimentation with the included Light Stage. Students can easily view a sample with the naked eye via its backlight.

High-Mag Lens
The High-Mag Lens (30x-1000x) can attach to the back of the mobile device, and the Light Stage can even be magnetically attached to it. And, when students move the High-Mag lens to the front camera, they can use the Circular Glass Slide and put liquid on the glass to view through the mobile device. And, if students create their own specimens using the Sample Stickers, they can easily store them in the included collecting album or any notebook.

The Light Stage, with the attachment of the stainless steel slide holder, can accommodate a regular glass specimen slide, too, and can be attached to the High-Mag Lens for viewing.


Another cool feature is that students can have both the Low-Mag and High-Mag lenses attached to the mobile device and switch back and forth between them, as illustrated in the video below.


The uHandy Mobile Microsoft Duet includes 180 sampling stickers for students to use for their own samples, 60 sample cards (which are called the Sample Hub) to create collections from their samples, and a collection album in which students can store their own samples and add notes.
Collection items included 

In addition to students using the Mobile Microscope Duet to complete classroom lessons, there are over 50 topics to explore found in the uHandy app. They include instructional videos at different levels of difficulty and projects for students to complete.

After putting the uHandy Mobile Microscope Duet through its paces and trying all the included options, I would recommend this for grades 6-12 science classrooms. It would make a great addition to a traditional science lab table as students could use their own mobile devices, capture the samples as images or videos, and use their findings in reports and for research purposes. Also, all the students can view a sample at the same time via a single, larger tablet, and discuss the topic of the lab as a group. The kits can also be used as content remediation or extension by having students work on the project topics included in the app.

I could envision a few kits put in the school library to be checked out so students could experiment at home. The only consumables that would have to be replaced are the Sample Stickers, the Sample Hub cards, and the batteries for the Light Stage. The kit could be used with younger students, but they would need adult supervision.

You can order the Mobile Microscope Duet package from the uHandy Duet Amazon page and you can save 15%, through September 12, 2019,  by using the promo code kathyBTS19

Fake news: Fact or opinion?

The following blog post first appeared on my Discovery Education blog in February of 2019, and is re-published here with permission.
__________________________________________________________________

Becoming a good digital citizen commonly includes the mastering of a multitude of skills. I like this image, created by Wesley Fryer and Marcia Moore, which provides a visual overview of the components.

The Digital Classroom Starter Kit from Common Sense Education provides digital citizenship activities and lessons as part of their classroom technology use ideas. They also provide a wonderful K-12 digital citizenship curriculum with the scope and sequence found here and have recently started updating their curriculum. You can visit their News and Media Literacy units here.

There are also many other sites which outline the nine elements of digital citizenship in detail as you can see from this Google search. Although these elements are all important, the element of digital citizenship I am most passionate about is the information literacy element. This great poster, in a post on ISTE’s site, describes it best:
"A good digital citizen applies critical thinking to all online sources and doesn’t share non-credible resources, including fake news or advertisements."


 http://staging.iste.org/sf-images/edtekhub/digcit-poster.png?Status=Temp&sfvrsn=2
But how can a student, searching the Web to learn something new, know if they have landed on a non-credible site? Without a knowledge-base in the topic, it may be hard for them to determine incorrect information. I have been working with critical evaluation of Web material since the inception of the graphical Web. As I created my Guide to Educators back in 1995, I realized early-on that determining credible information was difficult. I have critical evaluation worksheets on everything from Web pages to podcasts located here to help students think carefully about a site they are viewing or a podcast they are listening to.


However, non-credible information used to be more about accidental mis-information by someone who did not know enough about a topic or the unsure decision about the credibility of the author, not the intentional trickery, as it is seems to be today. We must work with students so they can both recognize biased information and know the difference between a fact and an opinion. These skills are life skills, not just Internet information skills!

Recognizing bias

Kimberly Moran, in her blog post on WeAreTeachers, provides seven tips for teaching students to recognize bias. Moran includes some great ideas and lessons, too. Here are a few of her suggestions.
  • Help students understand what the terms “fake news” and “news bias” really mean.
  • Provide an explanatory overview of each.
  • Give your students information that seems real and have them evaluate it. Here is a list of some sites I have identified as useful for student critical evaluation practice.
Moran also suggests teaching your students how to cross-check information. Have them look for conflicting information about the author of the text, images that have been edited, exaggerated claims, and use the “Links to this URL” on Google’s Advanced Search page to see if credible sites link to the one they are researching.

Here are some additional sites and resources to help teach about bias.
  • The Institute for Humane Education provides a list of sites to help educators recognize their own unconscious bias and how to teach students to recognize implicit bias.
  • Teaching Tolerance offers a lesson plan for students in grades 6-8 that “focuses on teaching students to identify how writers can reveal their biases through their word choice and tone”.
  • The MediaSmarts site provides high school students with the skills to recognize bias and point of view in newscasts and newspaper articles based on the language used in the story and also understand the role of subjectivity and perception in the media. This lesson plan includes having students deconstruct a news story based on language, story selection, and story order.
  • This character education lesson, Recognizing Bias, provided by Learning to Give, helps middle schools students, through a simple classroom activity, to understand about personal biases.
  • Discovery Education includes a 2:37 Common Craft video called Bias Detection. This short video demonstrates the importance of recognizing and accounting for bias when evaluating sources of information. It is intended for students in grades 6-12.
  • Humans as Variables (4:47) is another Discovery Education video clip and it is intended for grades K-5. Its purpose is to show students how a person’s bias could have an impact on a scientific study’s results.
  • The Facing History and Ourselves site includes an eleven lesson unit, Facing Ferguson: News Literacy in a Digital Age. This unit is to help students understand and recognize the choices facing journalists, explore the impact of social media on current-day news cycles, and become critical consumers of news. The essential question for the unit is:
"What is the role of journalism in a democratic society, and how can we become responsible consumers and producers of news and information in the digital age?"

Fact or opinion?

An information literacy topic, related to recognizing bias, is that of determining if something is a fact or an opinion. Oftentimes, students mistake well-stated opinions for fact. There are some great sites on the Web with information and tips to give students practice with the skills to know the difference..
  • Media specialists Donna Mignardi and Jennifer Sturge curated a list of resources to help middle school students recognize the difference between fact, opinion, and informed opinions. The sites they include focus on fact-checking lessons and resources.
  • A lesson plan by Scott Ertl is a guidance lesson for students in grades K-5. The lesson includes the comparison of fact and opinion materials in the news media. It also contains a guidance component titled “My Opinion Matters”. In this section, students practice positive responses to not-so-nice opinion statements classmates might make.
  • This lesson, posted on MediaSmarts, for grades 9-12, Fact Versus Opinion, was adapted from a publication by the Canadian Newspaper Association titled “News is not just black and white”. The lesson includes activities for recognizing bias and understanding how newspapers often include both fact and opinion in the same news story.
  • The New York Times Learning Network provides practice in determining fact and opinion in this lesson. Of course, the Learning Network has plenty of material to pick from, and provides links to real articles that students can discuss. The activities include use of pencil and paper, but students could just as easily mark them up on a digital device.
  • This mini-lesson from the Public Schools of Robeson County (NC) is an excellent resource for teaching the younger (grade 3-5) students about fact and opinion. The lesson includes explicit instruction and pedagogical tips for the educators, too! I believe that this min-lesson would also work for middle school students. Some of the components of the lesson can easily be completed using online tools, too.
  • Discovery Education includes materials for support of teaching and learning about fact vs. opinion for students in grades 6-8. The 4:21 video segment, Fact vs. Opinion, provides scenarios to help students recognize both fact and opinion in informational text.
  • The Author’s Purpose, another video clip in the Discovery Education collection, is a 4:24 video for grades 3-5. It helps students evaluate writings and decide if an author is trying to inform (fact) or trying to persuade (opinion).

I love Brenthaven!



If you follow this blog, you know I regularly review items from Brenthaven, a great company with an awesome focus on the educational market! Their designs are intended to withstand even the most careless student, with cases that can take being thrown in the locker, to headphones that have a breakaway plug for those students who get tangled up in wires easily. And, although we can try to control how the school's technology is treated while in school, we have little control over the out-of-school safety of the devices, as illustrated below! It is important schools invest in protective and proven device protection of the type Brenthaven offers.


"A mess of wires" by Marshall Vandergrift. CC license: CC-BY-SA. Flickr, 2007. 

Brenthaven allows me to look through their offerings and pick two or three I personally feel are items that would be great for schools! I view their collections with a different point of view each time. Sometimes, as I did in my previous reviews of the Tred Zip Folio and the Edge Carry Case for the iPad, I am considering ways the student devices can be kept safe when in and out of the backpack.

This time, I was interested in reviewing two backpack-- ones that work well for student and teacher smaller devices.


TRED SLIM PACK

Brenthaven's Tred Slim Pack backpack is made especially for the K-12 environment. I chose to review it because of its smaller size. With many schools supporting a 1:1 laptop initiative and providing students with digital copies of textbooks (with sets of paper textbooks being kept in the classroom), there is no need for students to carry the large backpack of a few years ago that weighed in, with books and larger devices, at 20-25 pounds.

Below is a video I created in 2013 illustrating this transformation of a student backpack because of smaller and more powerful technology tools and apps.


The Tred Slim Pack holds a 14" (or under) laptop or tablet, and the Tred's back zippered pocket is totally padded to keep it protected. The shoulder straps are also nicely padded.



In addition, there are two large zippered outside pockets that can be used for cables and power supplies, snacks, or even a water bottle. There is also a full-width horizontal zippered pocket located on the outside for a cell phone, sunglasses, or a wallet.




Brenthaven has included some specific features on the backpack to support its educational users. First, there is a reflective item on the front, back, and sides of the Tred Slim Pack to keep students visible and safe as they wait for the early morning bus or walk home in the late afternoons. In addition, the rear of the backpack includes a clear card pocket for easy access to gift students easy access to their ID card.

The Tred Slim Pack is very sturdy and protective, but also very lightweight at less than 1.2 pounds. Its external dimensions are 16.5" high, 11.5" wide and 4" deep. I loaded up the Tred Slim Pack with my 13" MacBook Pro, the power adapter and charging cable, my Apple XS Max phone, my headphones, a filled metal coffee travel mug, and a paper notebook. The full backpack weighed only 5.4 pounds!


Band for excess strap





Another nice little feature is the inclusion of a stretchy band to hold the excess from the backpack straps nice and neat. As one who hates those hanging straps, it is a great addition! And, again, it is a safety feature for students who might be riding a bicycle to school or any other activity that may cause loose straps to get caught.




The Tred Slim Pack would be a good choice for students in grades 4 -12 due to its smaller size and light weight! Give it a look, and, if you are considering this backpack which will protect the technology and the posture of your students, request a sample unit of Brenthaven's Tred Slim Pack to review!


COLLINS BACKPACK

Brenthaven also makes a line of bags and backpacks for educators. I am partial to the Collins series, which comes in graphite or indigo, and I already own the ones starred below. I decided I wanted to review the Collins Backpack.





The Collins Backpack is a feature-rich, professional-looking backpack for any educator. It is large enough to replace your "teacher bag" with lots of storage!

The side-load, fully padded and quilted laptop pocket can hold up to a 15.6" laptop. (I actually plan to use that area for books, papers , and a light sweater, since my 13" MacBook Pro fits nicely in the middle section padded, quilted pocket (shown on the left with the iPad in it).


This second full-size zippered section is an organized teacher's dream! It includes a smaller padded and quilted pocket that can hold a tablet, small laptop, or a sheaf of papers. The front of the padded section includes three pockets for power bricks, cables, and  a cell phone. The front flap of this section also includes a half-height zippered pocket to hold additional teacher necessities!

This section of the Collins Backpack is very deep and can hold notebooks, papers for grading, and your lunch bag, too! The dimensions of the entire backpack are 16.6" high, 12.5" wide, and 6" deep. It weighs practically nothing -- 1.8 pounds!

The front of the backpack includes two zip pockets. The top one could hold a cell phone, small e-reader, or a snack for the teacher's room. The second zippered section unzips on the top and right side and provides access to a key fob, a small padded pocket I would use for glasses or sunglasses, a pencil or stylus pocket, and a small slip pocket for a license, ID card, or credit cards.

I love the "vegan leather" bottom on the Collins Backpack since it is easy to sponge off after setting it on a dirty floor. If you load this backpack evenly, the 6" deep bottom will also allow it to stand on its own. The matching integrated handle on the top of the backpack is substantial and allows you another way to tote the bag. However, the padded back and backpack straps make the Collins Backpack comfortable to wear as a regular backpack, too!

If you are looking for a nice backpack to tote back and forth to school, take a look at the Brenthaven Collins Backpack!

Review of Vivi

As more schools move from interactive whiteboards to wall-mounted televisions or interactive panels, and from teaching in front of the roam to roaming the classroom, a simple screen mirroring and robust video streaming device is needed. This device needs to work with all platforms -- Windows, Mac, iOS, Chrome OS, Android, Linux DEB, and Linux RPM -- and be easy to use. It would be useful if it also included an administrative component to allow IT departments to manage the users and collect data on usage.

There is already a solution designed specifically for education called Vivi (http://www.vivi.io) that does all of this and more! I was sent one by the company to try out. 





I cannot speak to the administrative portal and central management components of the device at length since I do not have a school network to experiment with. However, I did have to use the admin panel to set myself up as a teacher user. You can find out more about the administrative portal here, view all the technical details here, and the company will gladly set up a demo to both showcase the Vivi's capabilities as well as answer any questions you might have!

PASSING CONTROL

The goal of the Vivi is to support real-time communication and collaboration in the classroom. The teacher is free to move about the classroom and mirror to the television or interactive panel. The teacher can give a student (or all students) control of the Vivi to share and showcase information with the entire class, too. 

Students can digitally "raise" their hand to ask for control from the Vivi app on their device as seen below. It does not matter what device they are using. This is a great feature for BYOD or 1:1 initiatives! The teacher is easily able to grant control by clicking on the student's name from the Vivi app on the their device.



Students can request control to screen mirror
Instead of worrying about a student in a nearby classroom requesting access to share their device's screen, you can put a 4-digit Room Code on your Vivi that your students need to type in to access the device. Also, once you have Room Code on your Vivi, you can give open access for your students to share their screens. Now, as with any code, you have to insist your students do not share the code with others. However, if you teach multiple classes, you probably will want to change the code regularly!

SHOWING VIDEOS

There are three ways teachers can show a video using Vivi

The first method allows you to copy an online video's URL from the Web and paste it into your Vivi app. The video will play through the Vivi and your teacher computer is free for other tasks, such as gathering additional information to share with students, monitoring a student chat about the video being shown, etc. View a training video about this feature here.

The second method is for you to play a video directly from your own device, rather than from the Internet. This is done by simply navigating to the video on your device through the Vivi app and clicking play! You will still have access to your computer screen for other tasks with this method.

The third method is called "Movie Mode" by Vivi. This option screenmirrors the video from your computer. When choosing Movie Movie mode as an option, there is a very short delay before the video begins to stream to allow for some buffering ahead of time so the video will play smoothly. To see more in-depth overviews of showing videos., check out this training video from Vivi.

Some of the options for showing videos through the Vivi

PAUSING A SCREEN

If you are mirroring your screen, and need to gather some additional resources for students, you can freeze a piece of content, like a Problem of the Day or a paragraph to read. While the content is "frozen", you are free to use your computer for gathering additional items of interest for students, opening a different app to showcase something else, etc. To learn more about the pause feature in Vivi, check out this video!

CAPTURING AND ANNOTATING

The capturing and annotation component of Vivi is very cool! First, you can mirror a piece of content from your computer screen via the Vivi app -- say projecting an unlabeled image of the parts of a flower or pausing a video you are currently showing. Students can then capture the image/video screenshot, use their Vivi app to pick the annotation tool, and annotate their own personal version of the image or video screen capture.

There are three choices to pick from when providing students with an image to annotate -- what is showing on their screen, an image from your device's photos, or a blank whiteboard students can create on.

Below is a sample of the student view of the annotation tools.


Student annotating an image captured with the Vivi annotation tool.

When students are done with their annotations, they can either download the annotated image to their device and submit it to you, or copy it and paste it into another document, like a shared Google Slide or another document of their own. To see this feature in action, view this training video!


MY EXPERIENCE

I wanted to put the Vivi through its paces, so I set up my Mac laptop as the "teacher device" and my iPad as the "student device". I attached the Vivi via HDMI to a television and via Ethernet to my Internet connection.

I printed out this useful PDF with a labeled overview of the features of the teacher dashboard in the Vivi app that provides a simple explanation of each of the teacher tools.

I logged in as a student in the app with no problem, but needed a presenter code (which would be supplied by your IT department) to log in as a teacher on my laptop, so I knew I had to open the admin portal.

The company had set me up as an admin, so I opened the admin portal from my computer and had to put in a change of PW to create my own so I could log-in. The default options in the portal were already turned on, such as allowing me to direct-play videos, share links in the app, etc.

I then plugged in the Vivi and it took a minute to show up on the television screen because it was setting up, but was ready to go in no time. I went back to the admin portal and noticed the Vivi I had plugged in was now showing up as a room, and, as an admin, I could change the splash image, manage the locations of the boxes, push out an emergency broadcast, and a ton more customization  options. Everything seemed quite straightforward and the user guides included were very detailed if I needed help, but I really did not!

On my "teacher device", I tried out all the features of screen mirroring, the different options to play videos, to supply the students with a static image to annotate, and pausing the mirroring. I found a feature I had missed, which was the ability to share a URL with all the students. The shared URL showed up in their Vivi app, and they just clicked on it!

I then turned to my "student device" and requested control access, and went through all those options available to students. One thing I learned -- if your students are using iPads -- is to have students turn on AirPlay and pick the classroom Vivi to mirror to. Another option I appreciated finding was, when a student has control and is sharing a video through their Vivi app, you can pause their video from YOUR teacher Vivi app if necessary. Just in case you want to discuss something...or something not quite right is on the screen!

The set-up and administration of the Vivi was straightforward, and the classroom use by teachers and students was simple. The mirroring from the devices was instantaneous, the streaming did not hiccup at all, and the pass-off of control from teacher to student was very easy!

If you are moving to televisions or wall-mounted displays in your classroom, take a look at the Vivi to allow freedom for you from the front of the room and the ability of students to share with others from anywhere in the room. Vivi is a winner!
