What is your comfort level with your learning system?

What is your comfort level with your learning system?

I often mention leasing a car when talking about a learning system. When you “buy” a learning system, you are actually leasing it. Sure, there are some vendors who will sell you the system outright, but then you either pay extra for the updates or you just have a system that never gets updated. Oh, and it has to sit either on your own servers OR you pay to host it somewhere.

Getting back to the car analogy.

Most people are equally excited and nervous when looking at cars. Some are worried about the salesperson making a b-line to you, others prefer the process, of looking, debating, wanting to see more and then go and find a salesperson to get a test drive done. The salesperson aggressive not withstanding, the end game is to get a test drive.

After a test drive, you will either want the vehicle or not. It is that simple. Then comes to the cost, and the negotiations begin.

When you select the vehicle you want, you are basing it on multiple factors, that have been identified in your brain, and solidified before you walk thru that door. If you are loyal to that brand, you will stay with it. If you have done your research ahead of time (a very common occurrence nowadays), you will have insight to make that buying decision. Very likely, there will be one key item that stands above everything else. Yes, the budget has to be there, but what is it, that stands above everything?

I’d argue comfort. You have to be comfortable when driving. It has to feel right, not bash your kneecaps, or make it impossible to pull back the seat enough, or the console become over distracting.

When I look at a learning system, regardless of the type, I am looking at multiple factors, and as I look, more items or inquiries will pop into my head, and then lead me down this path versus the next path. Yet, in the end, for me, comfort has to be there. It can do everything I need the system to do for a client (that I am representing) or for award considerations or for my rankings or for my research, but the comfort level isn’t there.

I’ve met people who will ask me what system should I buy – with some specifics – or what do you think of this vendor? When I provide feedback (general, since naming a few features, isn’t enough), I have had folks say, “But I love or really like X”. To which I respond, okay, then go with that system. Then the retort usually is, “but what do you think? Should I or should I not”?

At this moment, I know the comfort level isn’t fully there. The individual is seeking confirmation of their buying (or soon to be buying) decision, yet I’m not the one using or will be using the system, they will be. Comfort therefore plays a crucial role. You can provide confirmation, and yet, if you still feel like this is the system, then I say, go with it – but make sure it has what you need it to have, or will need to have down the road. If your gut says this is it, and your brain says this isn’t it, then, well, comfort is just not there.

Comfort Factors

I’m going to steer clear of specific features/functionality (for the most part), and limit pricing, because if the price is not in your budget, the comfort level won’t be there, no matter how much you try to think it is. Deep down, as my mom used to say, you will know.

When I examine a learning system, regardless of the type, I am going to go likely far deeper than you would, and that is okay. I’ve been doing this a long time, and see a few hundred systems a year.

To be comfortable, here are the initial set of items I am looking at in the system

  • Learner home page – Can the playlists or area/blocks be moved around? Or is it static? Static means that the playlists, the other blocks cannot be moved (they may be hidden, depending on the vendor), but if “in progress” is the first playlist, and “suggested” is the fourth, and you want “suggested” as the first, you are out of luck. Let’s say, announcements is in the block on the right side, at the top, and you want it at the bottom. With static, that is not feasible. Let’s though say you can move them around – okay, is it a template/theme that the admin selects – and picks what widgets are available and where they are OR is it where the admin allows the learner to move around the playlists, blocks, widgets via drag and drop, for example. I’m personally more comfortable with the last option, because it gives the learner full control of their personalized experience. Static doesn’t, and templates can be a mixed bag, depending on whether or not, the admin knows what widgets/blocks to add or which to hide. In the market today, the full learner control is in the minority of the industry. This is why, when a vendor says “personalized” it isn’t necessarily, truly accurate.
  • What is on that home screen? If the playlists are listed, is assigned first or recommended or suggested or in-progress? Assigned creates an often overlooked scenario, in that the learner never drops down to see the other playlists that are more elective to them. I am not a fan of assigned learning, as you all know. If you attended college/university, the General Electives – aka requirement subjects was the worst. What folks tend to like the best? The courses in their degree program (what they are going to study) and electives that do not have to be part of the GEs. I mean, Earth Science (no offense to geology majors), isn’t a subject area that you will be enthralled about, but hey if it is between that, and Clay Pigeons from the 15th century, you may think, “how bad can it be?” I’m talking about Clay Pigeons from the 15th century.
  • I like seeing the catalog – i.e. access to it from the home learner page. They click and go to the catalog page. Vendors seem to enjoy not using catalog as a term. I’ve seen “library” – which is acceptable, although there are vendors who have a resources/assets section too, so there can be confusion. One vendor I saw recently referred to it as “course market”, and it was a mix of content purchased ahead of time, by your L&D or Training department – 3rd party (Assuming you have purchased a seat/seats license from said publisher), content that you can select from your own company (free), or content that your company might be selling. This is not a good idea. A course or content marketplace is where content from 3rd party publishers sits – you the learner can’t see it – the admin, the head of learning or training or whomever, reviews, selects for the department, group, individual learners, and so forth, and then after paying it now appears in the learner’s catalog for them to choose/select to take. Catalog or a Course Library are comfort terms that any learner could understand. Some other term isn’t. If you, as the vendor, has to explain what that term means, this should immediately tell you, that it has to change.
  • Navigation on the header – I like this choice (this means it is at the top of the main home page), although some offer it on the left side – which I am fine with too, especially if I can hide the navigation – with a simple click. But again, the terms have to make sense – to anyone. I believe that every label should be changeable, because you never know what term my company uses or I want to use, versus what term you have defaulted to. Never assume that every label can be changed. Always ask. I do.

At every point, every area you look at, you should rate your comfort level. Write it down, so you will not forget. The first impression is often the right impression, or say gut and head align. This isn’t always the case with people, some can come off as jerks, but once you get to know them, you see them in a different light or perspective. When it comes to a system however, it can or should be very clear.

Comfort Rating System

I recommend creating a spreadsheet for the comfort level. Make it easy enough that when referring back to it, or comparing it to others who viewed the demo, everyone is on the same page.

  • Options are only one to three. That is to say, one, two and three. Anything more creates too much, I mean you are either very comfortable, comfortable or not comfortable. You are not, sort of comfortable, but maybe after lunch I will be more comfortable or after my nap.
  • On the sheet, it is either 1, 2, or 3. Not writing down, very comfortable, comfortable, not comfortable.
  • Make sure if you have a group reviewing the system, clear directions on what each number res presents is on the spreadsheet. Some folks create separate pages, then somebody can’t find that page, and just wings it. Never good. You decide what one represents, what two represents and what three represents.
  • Avoid the “well, I feel very comfortable when it is this” and sort of we need for definitions and explanation. No, no you do not. It is subjective – which is why you are given the three choices – it will be based on what you perceive your learners will feel. Remember, a comfort sheet is core, but it is not the only sheet you are looking at – or basing your decision it. The system has to have what you want, and need, and has to be in your budget. Comfort level, says okay – “the navigation has everything we need, but knowing my learners, I am not comfortable with it”. That is far different, than “the navigation has everything we need, and I am very comfortable with it.” – No where in that sentence is “my learners”. That’s the difference.

The comfort sheet applies to administration capabilities too. And it applies to support, and then, here is an additional one – your salesperson. I’ve done enough of these to tell you, that the salesperson’s approach and attitude will make a difference. Helpful is good, being arrogant is not. Unsure about a question – they will find out and respond within one business day. Unsure but just wings it, is not or unsure, will find out, but doesn’t respond within one business day is not. Even if they are still trying to find out, they should send an update. Maybe that person who knows is out that day, okay, “I just want to give you an update regarding your question….” – that is acceptable. Ignoring or not responding or waiting a week is not (even if they are going on vacation, they can have someone fill in and help out).

How many times have you heard, “Feel free to ask any questions during the demo”, and then when you do, they ignore you and just keep on blabbing? That is not something you want. It tells me immediately that they are likely down the road, to ignore and do whatever they do, PLUS they are going by script, and how personal is this?

I know of vendors who will send the prospect a video recording of a demo they did, thinking this will suffice. Or worse, point them to their web site to click and watch videos that are on YouTube or housed elsewhere. Talk about lazy.

Would you feel comfortable about this?

Cultural fit

This means different things to folks, but in the end, ask yourself, “Will I or we feel comfortable working with this vendor?” It should be a firm yes. Anything less, move on. You are not debating a menu item here. Go back to the car dealer. How did they treat you? Did you like your salesperson? What about the sales manager (or whomever helps close the deal)? Did you notice what other salespeople were doing? Were people smiling and looking like they enjoy it? How about service?

If you are purchasing the vehicle online and then just showing up to pick it up, you will still pick up some vibes. Even buying it online, did the salesperson follow your directions? Did they get everything you needed? Was it a smooth transition?

Now go back to the learning system. Will this be a smooth transition? Did the salesperson make you feel like you are someone they really want as a customer, or is it just about your money? Will they make sure that you get the system when you need it buy (assuming you do not change the project plan or come up with some things you needed after you thought about it, and forgot to tell them – in all the excitement?).

There are vendors I know, who make a wonderful system, but I would never buy from them, because behind the scenes, the cultural fit would be a concern of mine. They may be super nice people, but again, what you can’t see – but I see or hear, is enough to say, no thanks.

When I deal with a vendor, where I am representing a client, I will request a specific salesperson every time. I know the salesperson, just by working with them in the past. I know they will handle my inquiries quickly, and respond accordingly. There has to be a personality fit, because without it, this will be painful. The majority of vendors will do so, as I request. But yes, there are those who don’t. To me, this creates a concern. Think this way, you are at a trade show and meet Joe. You like Joe, you connect with Joe. You want to see a demo and talk more about your needs, so you contact the vendor or the vendor contacts you (scan of the badge) and then you find out the person talking to you isn’t Joe. Joe isn’t available, because you are not in his region, or map area or size of company or whatever. Now, if I am the vendor, and I know that Joe connected with you, and thus there is already a comfort level, why risk losing it, because that is not how your sales process works?

To me, that is a cultural issue – fit and says to me, “how flexible is this vendor really? If they can’t be flexible here, will they be if we end up going with them?”

Ditto on Implementation

Talk to the person who will oversee your implementation if you go with the vendor. Ask them questions, see how they respond. You should have a comfort level here. And yes, the same with support – talk with the person that oversees that department – because the support team – hopefully aligns to how support should be handled – from the manager’s or director’s or VP of Support’s approach and process. If the vendor won’t make that person available, why not?

There will be vendor who decline because you are not big enough, learner size. Okay, I will take my business elsewhere.

Think this way, if you ask to speak to a supervisor over the phone and the salesperson declines, what is your comfort level and more importantly what will be your feelings towards buying from that company, again?

Bottom Line

Comfort level – more importantly, your comfort level, plays a role in everything you do. Are you comfortable with the house/flat you are about to buy? Are you comfortable buying this or that product? Are you comfortable with the car salesperson you are dealing with? Are you comfortable knowing your neighbor is in the Witness Protection Program?

Being comfortable with a learning system, one where you are about to drop a chunk of your budget on, and provide to your learners or students or customers or members or whomever, has to play a key role.

Because if you are not comfortable with your decision,

How comfortable will your learners be,

When get uncomfortable responding to their

issues with the system, itself?

Maki Villano Is Earning His Master in Data Science While Balancing Work and Family

Karim Makisig “Maki” Villano studied electrical engineering as an undergraduate. He took on various IT roles over the last two decades and is currently a senior solutions architect at an IT services company. He soon became drawn to data science, recognizing that it was a growing field with high demand for skilled practitioners. Maki felt he could compete in the industry, but he needed to better understand data science techniques, tools, and technologies and how they overlapped with his work in IT.

He was interested in earning a master’s, but as a single father living in the Philippines, he needed to find a program that would allow him to learn the necessary skills without uprooting his life, work, or family. He was also concerned that he didn’t have a great deal of foundational data science knowledge.

When Maki found the Master of Science in Data Science (MS-DS) from the University of Colorado Boulder on Coursera, he was immediately attracted to the school’s excellent reputation and excited about the performance-based admissions structure. His lack of experience wouldn’t be an issue, and he could get started right away.

“In other programs, I would have waited months to hear back about my admission. With CU Boulder, I could jump right in and not waste any time.”

Maki enrolled in the Pathway Specialization, a 3-course series focusing on either statistics or computer science. By completing all three courses in one pathway with a cumulative 3.0 GPA or better, you’re immediately admitted to the program. This was perfect for Maki.

Once enrolled in the full master’s program, Maki was happy to find that the online format and in-course tools allowed him to process and absorb the material on his own time. He could absorb lectures while washing the dishes or folding laundry and rewatch videos until he fully understood each topic. He especially enjoyed his course with Dr. Anne Dougherty, who teaches Probability Theory: Foundation for Data Science:

“Dr. Anne Dougherty takes the care to explain the material and provides many ways of looking at a concept.”

Just one year into the program, Maki is already applying his new learnings to his current role;

“When we have to propose systems at work, my new statistics knowledge helps me calculate the parameters myself and make them more exact, and this allows me to do my work better.”

This fully online Master of Science in Data Science (MS-DS) from the University of Colorado Boulder is an ideal choice for career-focused learners eager to benefit from a comprehensive, multi-disciplinary approach. This program leverages unparalleled faculty expertise across statistics, data science, computer science, natural language processing, information science, and more.

When Should You Tip?

When Should You Tip?

How often do you tip? Do you see tip jars or touch-screen systems for tipping in your neighborhood businesses? What about ice-cream parlors, bakeries or movie theaters?

Do you tip whenever you are asked or prompted to? How much do social pressures influence your tipping practices?

In “To Tip, or Not to Tip?” Christina Morales writes about how the pandemic, and new technology, have made tipping more ubiquitous and easier than ever before.

Last year, Anna Johnson found herself using an electronic screen to pay for a pickup order at a bakery in Phoenix, a normal enough experience at many food businesses she frequents. But this time, she was bewildered when the machine recommended that she tip as much as 35 percent — on cookies.

“It just surprised me that they’re asking everyone for that,” said Ms. Johnson, 66. “People can’t afford to keep on paying more, more and more.”

Tipping fatigue like Ms. Johnson’s is real, and it is widespread.

In the thick of the pandemic, Americans like her dug deeper into their pockets to recognize the hard labor and health risks taken on by workers in every corner of the food business — servers, cooks, cashiers, delivery workers. For many customers, adding 15 percent or more for a takeout meal or grocery delivery felt like the least they could do to help essential workers.

Covid cases are on the rise again, and the risk to restaurant workers is still elevated. But as business has returned to something more like normal, many customers and experts in the hospitality industry say that deciding how much money to leave, or whether to leave a tip at all, has become a tougher decision — complicated by new technology, and requests for tips at food business of all types, from bakeries and yogurt shops to food trucks and juice bars.

In interviews, customers, including some who have worked in the food-service business, said they felt uncomfortable with the many requests to tip, and pressured into giving more. Higher menu prices, a result of inflation, have raised the amount of a traditional 15 or 20 percent tip. In some cases, restaurants are adding service charges and gratuities to the bill that some diners may not notice right away.

  • What is your reaction to the article? Do you feel that “tipping culture has gotten out of control”? Why or why not?

  • How do you decide when to tip and how much? Did your tipping practices change during the pandemic? Explain.

  • Do you think there are situations when tipping should not be expected or allowed? Why?

  • Do you, or does anyone you’re close to, rely on tips for income? How do you feel about changing expectations around tipping?

  • As a teenager, without the income of a full-time job, how do you navigate tipping? The article mentions a college student, Janhavi Bodkhe, who described feeling social pressure to tip. Have you ever felt this way? How do deal with tipping as a young person?

  • In a New York Times guest essay, Michelle Alexander writes about the racist roots of tipping in the United States:, “After the Civil War, white business owners, still eager to find ways to steal Black labor, created the idea that tips would replace wages.” Ms. Alexander advocates raising wages instead of making workers rely on tips. What do you think of this perspective? Do you agree with the argument to get rid of tips and replace them with higher wages? Why or why not?

  • Word of the Day: verve

    Word of the Day: verve

    The word verve has appeared in 136 articles on NYTimes.com in the past year, including on May 6 in “The Deeper Meaning of Elvis in Australia” by Damien Cave:

    According to Elvis tribute artists — and Elvis’s former tour manager, who made the trek from back home in the U.S. — Australians of all social classes, political persuasions and ages were more likely to dress up, sing, march in the parade, or play rugby, all while dressed up as Elvis, all while encouraging each other to get involved and have some fun.

    The Australian festival was unique because the lines between serious and silly were blurred. While Americans listened and admired Elvis, Australians made him their own.

    I’ve written a lot about that Australian penchant for pulling people into an activity … But in Parkes there was an extra layer of verve that only the combination of Elvis and small town Australia could possibly provide. My daughter loved it. So did I.

    Lesson of the Day: Photos of the Past

    3. How do the photos help tell the story? Which photos did you spend the most time with? What drew you to them?

    4. What story do the photos tell when looked at together? Glance back at the order of the photos. How does the order work, or not work, to tell the story?

    5. Did you have any feelings about any of the photos? What were they? Did they remind you about anything you’ve seen or experienced?

    6. Which, if any, photos did you find the most beautiful? The most informative? Both? Consider facial expressions, body movement, clothing, the surroundings or how the people in the photo are interacting with each other (or not).

    The articles in “Past Tense” show how archival photographs can be used to tell a story about a specific event, topic, person or place, and show readers a different period in time.

    Try making your own photo story about an era of your choice, either using online photo archives or your own family photos. Here’s how:

    1. Choose a subject: Think about a theme, topic, person or place from history that you’d like to know more about. For example, the civil rights movement, Halloween or street musicians. If you’re not sure of a topic, try searching online for a time period — like the 1970s — and see what comes up.

    2. Then, search the archives: Here are some online collections you might dig through:

    3. Find a story: As you look through the archives, begin to zero in on a story you’d like to tell. What patterns, themes, trends or narratives do you see emerging? You might start to limit the search of your topic to a specific time period (such as Halloween in the late 1960s and 1970s), to a specific location or to a specific person.

    How Good Are You at Handling Challenging School Work?

    How Good Are You at Handling Challenging School Work?

    As students readjust to school after two years of pandemic learning, many are striving to rebuild their academic confidence. Some educators believe this is a crucial moment for teachers and parents to keep their distance when learning becomes difficult, and to be explicit about the fact that the challenges students may be facing can offer great rewards.

    How often do you struggle with challenging school work? Do you get frustrated or overwhelmed? Or do you embrace the opportunity to deepen your learning?

    In “Learning the Right Way to Struggle,” Jenny Anderson writes about some common educational strategies that lean into the idea that, in the classroom, challenges are something to embrace:

    When Hunter, 6, started first grade last autumn, he struggled to match letter sounds with the shape of letters on paper. He found writing letters hard and writing words even harder. “It felt bad,” he said recently.

    But Hunter also knows how to articulate what is happening when things get frustrating. “Your brain grows at the bottom,” he said. It’s a phrase that refers to the bottom of the learning pit, an imaginary place where students in Hunter’s class in Illinois have been taught to go when something they are learning gets difficult. Hunter also knows what he needs to get out of the pit — hard work, his friends, his teacher — and what it feels like when he climbs up and out on the other side (“excited”).

    The learning pit as a metaphor is one of several common educational strategies that lean into the idea that struggle is something to be embraced. It was conceived in the early 2000s by James Nottingham when he was a teacher in a former mining town in Northern England. He saw that his students, many of whom were low income and lived in communities with high unemployment, avoided leaving their comfort zones. He wanted to encourage his students to get comfortable with being a little uncomfortable.

    At a moment when students are reeling from two years of pandemic learning and isolation from their peers, the idea of intentionally making young people uncomfortable may seem misguided. But many educators and learning scientists say that now, as students look to rebuild academic confidence, is a crucial moment for teachers and parents to step back when learning gets hard, and to be explicit that the challenge offers rewards.

    “The answer isn’t taking away challenge, it’s giving more tools to deal with challenge,” said Carol Dweck, a professor of psychology at Stanford University and an expert on constructive learning mind-sets. Instead of saying “kids are too fragile” and refraining from offering difficult tasks, Dr. Dweck said, using frameworks like the learning pit can help children visualize ways to push through by asking for help and stepping up the effort.

    “It becomes a way of articulating what might in the past have been humiliating and uncomfortable and discouraging,” Dr. Dweck said.

    Students, read the entire article, then tell us:

    • In general, how often do you struggle with school work? Has it felt more burdensome in the last couple of years? What subjects do you find the most difficult? How do you respond when faced with challenging assignments?

    • Is it easy for you to admit that you don’t understand something? How willing are you to ask for help? Do you wish you were better at either at asking for help, or having the confidence to try to solve problems on your own?

    • Share a specific time when you felt challenged or disheartened while trying to learn something new. What emotions and physical sensations did you experience? How did you get through it? How did you feel once the knowledge “clicked,” if it ever did?

    • What tools — for example, picturing a challenge as a “learning pit” — do you use when you encounter difficult work? How do they help?

    • As the article explains, some researchers believe that students learn new concepts more fully, and retain the knowledge longer, when they engage in “productive failure” — grappling with a problem before getting instruction on exactly how to handle it. Do you believe failure can be an instrumental part of learning? Has it been true in your experience?

    • John Hattie, a researcher who spent 15 years studying the things that influence learning, said that one key factor is striving for a challenge, and not “just doing your best.” Do you agree? Should people constantly push themselves beyond their limits to be better, even if it likely means pain, discomfort or defeat? Why or why not?

    Tasty Tilapia: Your Next Bandage?

    This essay, by Qi Yao Mak, 15, from Shanghai High School International Division in Shanghai, is one of the top eight winners of The Learning Network’s third annual STEM Writing Contest, for which we received 3,564 entries.

    You can find the work of all of our student winners here.


    A slimy, grayish, thin rectangular patch was put on the electrician Josué Bezerra Jr.’s burn wound. But that flap of scaly, stretchable skin wasn’t just any bandage. It could be lying on your dinner table now. Meet the humble tilapia, the new Brazilian savior.

    Brazil’s hospitals lack ready supply of the usual human, pig and artificial skin needed to satisfy burn treatment demands. So, doctors often use sulfurside cream and gauze to dress wounds, which requires painful daily dressings. Dr. Edmar Maciel then thought to use tilapia skin, which was readily available, as an alternative bandage. In 2015, he started preclinical trials with tilapia skin at the Federal University of Ceará.

    The treatment begins with doctors cleansing the fish skin with multiple solutions, then sending it to São Paulo for radiosterilization, ensuring that it’s virus-free. Tilapia skin can last up to two years after sterilization.

    During treatment, doctors disinfect the wound area thoroughly before applying the sterilized tilapia skin. The skin covers the wound area and stays on until recovery, just like a permanent Band-Aid. Tilapia skin “prevents loss of moisture and proteins on the wound and it stays bonded to the bed of the wound until it heals over,” Dr. Maciel said. This process helps the wound to recover faster and protects it from contamination. Moreover, tilapia skin has high type I collagen content. The collagen component promotes the growth of fibroblasts, a type of cell in the connective tissue, helping the wound patch up and generate new layers of skin. Eventually, the tilapia skin will dry out — no need for the daily changing that cream and gauze require.

    Surprisingly, the tilapia approach was more effective than the cream and gauze. Dr. Maciel’s 2017 Phase II study compared the traditional method with the tilapia bandage. One hundred fifteen outpatients ranging from 18 to 70 years old participated in the study. Half used the conventional method; half used tilapia. On average, the tilapia group took 1.43 days fewer to regenerate their skin and used 3.72 fewer dressings than the gauze and cream group.

    “I didn’t take any antibiotics or pain medication. At 13 days, it was already scarring over,” Mr. Bezerra reported, satisfied at his speedy recovery.

    Compared with other types of skin bandages, tilapia provides more benefits. Pig and toad skin have limited usage because of the risk of animal disease infections. Human skin banks rely heavily on donors; however, each check-passed donor can only provide one-third of his or her total skin. On the other hand, tilapia skin comes readily from tilapia fish farms as a waste product and has no risk of infection.

    The American Burn Association reports that around 450,000 burn patients need medical attention each year. That rate is higher among low- and-middle-income countries, such as Brazil and many more. Fortunately, at least 500 burn victims have received the tilapia bandage. Doctors hope that it can reach more patients in the years to come.
