Lucky 7: New Courses Coming for Fenwick’s 92nd Academic Year

Four advanced computer science classes, one advanced theatre class, Mandarin and yoga headline exciting curriculum additions for Friar students and teachers!

By Mark Vruno

The Fenwick administration and faculty are excited to offer several new courses to students this coming school year. A series of four Advanced Computer Topics (ACT) classes as well as a new World Language course (Mandarin), an Advanced Theatre class and a new Physical-education class (yoga).

In discussing the new Advanced Computer courses, “Close to 30% of Fenwick’s graduates pursue a degree in STEM [science, technology, engineering or mathematics],” reports Computer Science & Physics Dept. Co-chair Dave Kleinhans. “Our investment in courses and physical spaces must match this interest.” The school’s new Computer Science Engineering & 3D Printing Lab, which debuted in the fall of 2019, will support four new advanced Computer Science (CS) classes: Data Structures & Algorithms, Introduction to Robotics, 3D Printing and IT Fundamentals for Cybersecurity.

The four, half-credit “ACT” classes are designed for students interested in diving deeper into the so-called computer sciences. They will have the opportunity to explore specific topics beyond the College Board’s AP Curriculum in an online format during scheduled CS class time. Each course has a programming or computer-aided design (CAD) requirement and is taught via an online, education-software platform.

“These topics represent areas that provide valuable preparation to students interested in pursuing technical disciplines — and those that are hot in today’s computing market,” adds CS/Physics Teacher Don Nelson. He should know. Mr. Nelson spent 30 years as a business person/nuclear engineer before embarking on a second career in education. (Prior to coming to Fenwick in 2019, Nelson taught at the Illinois Institute of Technology and DePaul Prep, formerly Gordon Tech.)

“Each of the classes offers students with experience and advanced knowledge of CS through two primary activities,” Nelson explains:

The online format is offered through Coursera and more than 100 partner universities (e.g., University of Illinois, Northwestern) and private corporations (e.g., IBM).
A capstone project complements the online format with a hands-on application of the concepts presented.

Upon successful completion, the student will receive a digital certificate and hands-on experience valued by universities and prospective employers. “With Don and our five other engineers serving as teachers here, combined with our recent physical space and course investments,” Mr. Kleinhans continues, “Fenwick is uniquely positioned in the high-school arena to serve students interested in STEM.” (See sidebar for additional course details.)

“If you want to talk to someone, speak in your language. But if you want to connect with someone, speak in theirs.”
– Nelson Mandela

Mandarin I (1.0 credit)

“The sixth language offered by Fenwick will be Mandarin [Chinese],” reports Principal Peter Groom. It is the language of government and education of the Chinese mainland and Taiwan (with the notable exceptions of Hong Kong and Macau, where a local dialect of Chinese called Cantonese is more often used.) Mandarin is one of five major regional languages of China.

At admissions-sponsored events over the past two years or so, “we have heard repeatedly from families that this is an area we needed to seriously consider,” Mr. Groom continues. “We have a current freshman student with some background in Mandarin.” He adds that the language fits within the wheelhouse of faculty member Shana Wang, who offered to teach it as a pilot program this school year.

Last year, incoming Friar prospect Dylan Zorovich ’23 “was looking for a language but could not find it at Fenwick,” recounts Ms. Wang, who describes the free-thinking freshman from Elmhurst, IL, as both “diligent and delightful.” In true Dominican fashion, mentor and student set out on a journey this past August. “Our quest? To find a common language,” says Wang, who has taught in China.

The full-fledged course next school year seeks to provide a lively and challenging introduction to the basics of reading, writing, speaking and listening in Mandarin. Students will aim to identify at least 300 Chinese characters by the end of the year and write at least 150 Chinese characters using the correct stroke order. These characters are used to construct simple sentences while employing the proper grammatical conventions. In addition to learning Chinese characters, students will partake in continuous speaking and listening practice. They will watch videos, listen to dialogues and make presentations about important historical figures and events in China, Taiwan and Singapore. There will also be a focus on various Chinese cultures and their specific contributions to the global society.

Theatre II (0.5 credit)

This course is geared toward musical theatre, performance and design, building on the student experiences learned in Theatre I (which is a prerequisite). Students will engage in activities including music and text analysis, staging, scene analysis, choreography, theatre tech, lighting design, stage management and production. The course will culminate with a musical revue including solo and group numbers. The skills learned will not only enhance students’ musical theatre experience but also expose them to careers off the stage.

“Theatre I is for students with no theatre background,” Mr. Groom notes. “This second-level addition will attract those who do have some background in theatre.” Therefore, previous experience is required, as is approval from Theatre Teacher Mr. Caleb Faille, whose responsibilities within Fenwick’s Expressive Arts Dept. gradually have been increasing. “Mr. Faille now is in charge of our spring musicals,” Groom reports. An additional benefit is that Blackfriars Guild members can study their craft during the school day, he adds.

“Yoga is like music; the rhythm of the body, the melody of the mind and the harmony of the soul create the symphony of life.”
– B.K.S. Iyengar

Yoga (0.5 credit)

Also coming to the Fenwick curriculum in 2020-21 is a yoga course, “which can fulfill the P.E. [physical education] requirement, for sophomores,” Groom says. Expressive Arts Chairperson Rizelle Capito will teach the course. She has conducted yoga instruction for Fenwick faculty as well as for the varsity football team.

Ms. Capito says, “Studies and research have shown that yoga and mindfulness exercises not only promote physical health, but also mental health. Our students are under a lot of pressure and stress and we need to provide them with healthy ways of dealing with their stress. The class will include the physical practice of yoga to build physical strength and flexibility, meditation and mindfulness exercises. The hope is that the students will take these tools and incorporate them into their daily lives as a means of staying both physically and mentally healthy.”

Sophomores have the option to choose a regular PE class or yoga as their physical-education credit. (Placement is not guaranteed and is dependent on period availability and scheduling.) The course is designed to introduce students, safely and accessibly, to the basic postures, breathing techniques, and relaxation methods of yoga. Areas of focus will be on low-impact activities to improve overall flexibility, strength, core and cardiovascular endurance.

Fenwick Launches Engineering and Innovation Laboratory

Facility represents the ‘stem’ of flowering course offerings in science, technology, engineering and mathematics.

By Mark Vruno

Science Department Co-chair Mr. Dave Kleinhans (right) works with a student on a laptop computer in the new STEM-focused facility.

Fenwick High School has ushered in its 91^st academic year with a new Engineering & Innovation Laboratory. At the Open House in late September, prospective students and their families had an opportunity to see the modular classroom (Room 57), which features 25 new drafting and programming laptop computers, six 3D printers and five interactive, “smart” monitors. These technology equipment upgrades are a major part of the more than $70,000 investment in the refurbished lab space.

“We are teaching in the lab to packed computer-science classes,” Science Dept. Co-chair Dave Kleinhans reports. In an effort to prepare students for business and STEM (science/technology/engineering/math) degrees in college, he adds, many of these courses were co-developed with a University of Illinois, student-run consulting organization. At professional-development sessions in mid-September, faculty members received training on the three-dimensional (additive-manufacturing) printers.

Principal Peter Groom adds, “The development of our Computer Science curriculum has been a collaborative effort. We put a lot of faith in our faculty, and they really ran with it. In some cases, our teachers took existing courses and tailored them to the 21^st-century world,” Mr. Groom explains. “In other cases, we started brand new courses. The opening of the new lab is just the beginning of a facilities transformation that will allow our excellent CS/Physics faculty to maximize the student experience.”

Fenwick’s Engineering & Innovation Lab “is what software labs look like at some of the companies I still communicate with in the private sector,” notes Kleinhans, who started up three software firms over two decades before embarking on a career change to become a teacher. IBM (Cognos) acquired one of his companies, but Kleinhans insists that teaching and mentoring young people bring him far more satisfaction and joy “than any bonus check for selling a company or being a CEO.”

Mr. Don Nelson (center) joined the Fenwick faculty this year to help run the computer-science segments of the new lab.

Joining the Fenwick faculty for this school year is Donald Nelson, who is “taking over a lot of our CS [computer science] classes,” according to Kleinhans. “Principal Groom made a great, strategic new hire in Nelson,” Kleinhans believes. “Don is a 30-year business person/nuclear engineer who wants to be involved with students as a second career.” Nelson, who previously has taught at the Illinois Institute of Technology and DePaul Prep, holds a B.S. in engineering from the University of Illinois at Urbana-Champaign and an M.S. in computer science engineering from the University of Wisconsin at Madison.

Student input and involvement

“It was inspiring to watch Dave Kleinhans empower recent graduates and current Friars to be project managers for the new lab,” adds Math Teacher and alumnus Kevin Roche ’05. “Kevin Brosnan ’20, Spencer Gallagher ’19 and Jack Vomacka ’18 [helped] make it all happen. They met with architects, researched the best equipment, presented to the Board and even were present for the painting and carpeting subcontractors to ensure the job got done. That was my favorite part of it all: those three gain valuable project-management experience thanks to Dave.

Young Alumnus Warns That Website ‘Cookies’ Are a Major Privacy Concern for Consumers

Cookies Are Not as Sweet as Search Engines Want You to Believe, Says 19-year-old DePaul Freshman

Editor’s Note: 2018 Fenwick graduate Nick Bohlsen, of Oak Park, is finishing his freshman year at DePaul University in Chicago. Bohlsen wrote this paper last semester for his “Writing Rhetoric and Discourse 103” class, earning an “A” for his effort. (A Networking Infrastructure 263 course also used a more detailed version of this report.)

By Nick Bohlsen ’18

In our modern society, our lives are becoming more intertwined with the Internet. We shop, watch television, talk to distant relatives and conduct business intercontinentally thanks to the Internet. The Internet is undoubtedly one of the greatest inventions in history, but it is not a paradise like the Internet Service Providers (ISPs) and the major search engines advertise it as.

As you browse through your aunt’s random photos on Facebook, for example, you may notice that the advertisements seem to be tailored to show you products that you may be interested in. They are not there by accident, but intentionally placed based on the data that web browsers and sites collect on you. As we visit sites, they start to collect key identifiers that puts us into various advertising categories. These key identifiers are called “cookies.”

Cookies are generated with every single move that we make on the Internet and hold data relevant to what we are doing: data such as passwords, credit card information, items in an online shopping cart, and more. The data gets stored onto the local machine and waits for the next time it can be used on the web. In a perfect world, this data would never be accessed by anything other than the website that originally generated the cookie. Our world, especially our online world, is not as safe as we would want it to be. The question that is raised is should internet sites and search engines be allowed to track all of this sensitive data? Should they be allowed to send this data to advertising agencies to be able to specifically target our interests? The simple answer: absolutely not.

One of the larger issues with cookies is the amount and kinds of data that is being tracked. As mentioned before, cookies are collections of data that track what we do on the internet. This data can be something as small as our search trends to something more personal such as credit card information or social security number. Editor John Rockhold, in his article titled “How the Cookies Crumble” published in Wireless Review on June 15, 2001, quoted Jason Catlett, the president of Junkbusters. Junkbusters was a company whose goal was to advocate for consumer privacy in an era when the internet was an emerging technology. Catlett said, “Cookies were meant to be a way of storing shopping-cart information, but they quickly turned into an all-purpose surveillance mechanism” (Rockhold). This surveillance system was originally designed to work as a “working memory” for sites to make our lives easier.

Cookies have evolved into something more than that now. Advertisers on the internet are now using the data from our cookies to see what we are interested in. According to Stephen B. Wicker and Kolbeinn Karlsson, writers for The Association for Computer Machinery magazine, there are many processes in the background that put our information up for auction. Simply put: Our data gets sent all over the web to categorize our search trends, build profiles (or update ones that have already been built on our data) based on the data that was tracked. Advertisers then look at our profiles to see if displaying their ad will be cost-effective. The advertisers that find our profile attractive bid on the ad space, an advertiser wins the bidding, and their ad gets displayed on your screen. All of that happens within 100 milliseconds. (Wicker & Karlsson, 70)

Internet ad delivery is a complex process involving multiple redirections, synchronizations of user information and an auction, all in a few tens of milliseconds. (Wicker & Karlsson, 70)

According to Jane Quinn – writer for Newsweek who published the article “Fighting the Cookie Monster” in February 2000 – these profiles have plenty of our data. Her example: Say you’ve sought information about a debilitating disease, spent time in a chat room for recovering alcoholics, or gambled online. The Web sites you visit may be attached to your personal name, address, e-mail address or even phone number. Technically, searches can even be launched for key words … that you might have left in a chat room or on a public bulletin board. These records — the intimate and the mundane — can trail you for life, like Marley’s chain (Quinn).

Advertising agencies usually like to share their databases with one-another to build the perfect digital picture of you, increasing the amount of information they have from you (Quinn).

The benefit of allowing the advertisers and companies that use this data is that we will never see an ad that has no meaning to us; nor will we ever see an ad more than once. They also claim that there would be fewer free sites on the internet without the intensive tracking (Goldsborough). The one that benefits the most from this agreement, however, is the advertiser. At the cost of our information, they display advertisements to us that they are more likely to get us to click on them. They get more money from their advertisements and more of our information to target us even more efficiently. That is a parasitic relationship in which the parasite gains while the host loses.

Another reason these sweet morsels of our personal data should not be so readily accessible is the possibility of our private information becoming not-so private. Vint Cerf and Bob Kahn – the inventors of the internet – were not worried about security in their initial designs. They viewed the internet as one happy place where everybody would play nice with each other and be responsible. As we know, that is not what the ecosystem of the internet is today. As this data is being sent back and forth on the web, it is possible that someone can break into the system and intercept our personal information.

One potential problem, according to Reid Goldsborough who is a writer for Tech Directions, is that, “…the theft of the user name and password information by hackers who could then access your bank, credit card or other account” (Goldsborough). These kinds of breaches are more common for mainstream sites such as Yahoo and Google; the smaller sites are much more prone to security breaches. These “third party” sites can have intentional data breaching code built-in or can be exploited by an outside user that is interested in your data (Goldsborough).

Although there is a way to reduce the number of cookies we have by deleting some, the settings that allow us to do so are usually hidden under multiple menus. That is also assuming that the user knows that they should delete their cookies every now and then, or that cookies even exist outside of the kitchen. According to the findings of Jeremy Kirk – a writer for PC World magazine – there are some very devious ways in which some of your most trusted applications can be turned by a hacker to exploit your cookies. He found that, “…some top websites using a method called “respawning,” where technologies such as Adobe’s Flash multimedia software are manipulated to replace cookies that may have been deleted” (Kirk). Adobe Flash is used on almost every website that we go to, including sites such as D2L [the cloud software used by DePaul and other schools]. Once the exploit in Flash has been run on your computer, hackers get every piece of information that you have ever inputted to the world wide web.

If today’s internet looked just like Cerf and Kahn’s idea, then we would not have this problem facing us today. As that view is virtually impossible to achieve, we must do all we can to protect our privacy in the digital age. Having our personal data stored and sent all over the internet is a very dangerous practice, and it is something that the public does not know enough about. It is up to us as users of the internet to do our due diligence and ensure that our privacy is being protected, and to reduce the number of cookies that are being generated based on our private information.

High-Tech Education Came to Fenwick a Quarter-Century Ago

Where in the World Wide Web has “FenTech” gone and, more importantly, where is it headed? Answers can be found in the growth of the school’s Bernard F. Brennan Computer Science Laboratory and CS programs.

By Mark Vruno

In 1993, could we have fathomed high-school educators teaching entire courses to teenagers on tablet computers? iPads weren’t even a tech “thing” 25 years ago, yet this past school year at Fenwick, the “Introduction to Computer Science” (CS) class was taught entirely on Apple iPads, reports Science Department Co-Chair Dave Kleinhans.

Turning Fenwick’s tech visions into realities over the past two-and-a-half decades has been made possible, in large part, by initial, generous funding from alumnus Bernard Brennan ’56, former chief executive (from 1985-96) of the Montgomery Ward department-store chain. Bernie is the younger brother of the late Edward Brennan ’51, former CEO of Sears, Roebuck and Co. Ed and Bernie, the Brennan Bros., are a couple of Friars’ heavy-hitters: Bernie is a member of the school’s Board of Directors as well as a 1986 Fenwick Hall of Fame inductee; Ed followed him to the school HOF in ’91.

A peek inside Fenwick’s Bernard F. Brennan Computer Science Laboratory, which officially was dedicated on February 28, 1993.

Twenty-five years ago, the younger Brennan and his family made a major leadership donation to create the Bernard F. Brennan Computer Science Laboratory, which was dedicated in early 1993. Students at the time, as well as members of the Fenwick Mothers’ Club, also contributed financially to the lab’s creation. Now 80 years old, Bernie Brennan’s blue-sky vision of “computerization projects” today partly resides in the virtual “Cloud,” of course. But keep in mind that, in early 1993, while email may have been a mainstream form of communication at most corporations, the Internet was a fledgling technology. Ever so slowly, companies were beginning to launch new, online branding devices called “websites.” The dot-com bubble (1997-2001) was still a few years off.

For Fenwick’s new Brennan Computer Lab, initial purchases in the mid-1990s included hardware, such as AST Bravo workstations and Netstore SCSI CD-ROM subsystems (used for information retrieval long before web browsers and cloud computing became popular), as well as software, electrical upgrades and accessories, including printers and furniture. The lab was designed to be used by the Math and Science Departments as well as the Library and the English Department. Tech-hungry teachers welcomed the new writing-lab segment, which featured desktop publishing systems for the Blackfriars Yearbook, The Wick student newspaper and staff newsletters.

“It was clear to me that we were moving into the technology world at that point in time, and I wanted Fenwick to be in the leadership position,” Mr. Brennan reflected recently. “Ironically, I have been heavily involved in the technology sector for the past 20 years! It is easy to give back to Fenwick and our Dominican friends as they have done so much for the Brennan family. Fenwick’s focus on intellectual curiosity, discipline and uncompromising ethics is a beacon for us all.”

New Millennium’s Web of Tech

It is interesting to note that each of Fenwick’s 1,152 incoming students this fall will have an iPad in her or his backpack. (Members of the outgoing Class of 2018 are the first Friars to have had tablet computers in their collective possession all four years.) With improved anti-cheating security measures in place, some high schools in Illinois already have adopted online final exams. Fenwick teachers have administered online quizzes and tests via their students’ iPads, but most educators in the building are proceeding with caution on that electronic front.

Since 2000, Fenwick has had a Technology Services Department in place that today is staffed by four full-time employees. These high-tech staff members manage the school’s more than 400 computer systems and a highly secure Wi-Fi network as well as some 30 switches and 122 access points — not to mention the telephone and email systems and 92 copy machines/printers! Associate Tech Director Fr. Mike Winkels, O.P. also feeds content to a total of six electronic bulletin boards displayed in the cafeteria, outside the library and elsewhere throughout the school.

Fenwick’s students, faculty and staff alike often take this tech group’s behind-the-scenes work for granted. Even those of us old enough to remember slow modems and non-connectivity have come to expect our 21^st-century, networked, electronic devices to work – “magically” — with no glitches. “We do a lot of things that people probably don’t think about,” says Director of Technology Services Ernesto Nieto, who came to Fenwick in ’01 by way of St. Ignatius College Prep, the Dominican Conference Center, the Shrine of St. Jude and DePaul University.
