Century 21 Software

[Exequiel Mondragon]

Iwas taught early to make sure I call on all students daily. They like being recognized. Technology helps. Technology allows all students to have a voice and a chance to show what they know.

Connecting with other educators to share and collaborate helps ensure our success. We can of course do this face to face or in curriculum groups, but we can also stay in touch via Twitter (you can reach me at Project Spotlight @edspotlightdiv or @MountainsTeresa) and other social networks.

I found that being involved in the Teacher Leadership Initiative this past year helped me connect with excellent teachers across my state and our nation. I also stepped up to take on more leadership in the Billings Education Association (I am a director at large), went to Jump Start training to start the process for National Board Certification and attended AP training for Spanish.

The first couple of years for the 21st-century educator can be stressful, but also rewarding. Each year, you will get closer to becoming a master teacher. Always believe that each of your students can and will succeed. Best wishes in your teaching journey, for it truly is a calling.

Although a century can mean any arbitrary period of 100 years, there are two viewpoints on the nature of standard centuries. One is based on strict construction, while the other is based on popular perception.

According to the strict construction, the 1st century AD began with AD 1 and ended with AD 100, the 2nd century spanning the years 101 to 200, with the same pattern continuing onward.[note 1] In this model, the n-th century starts with the year that ends with "01", and ends with the year that ends with "00"; for example, the 20th century comprises the years 1901 to 2000 in strict usage.[2]

In popular perception and practice, centuries are structured by grouping years based on sharing the 'hundreds' digit(s). In this model, the n-th century starts with the year that ends in "00" and ends with the year ending in "99";[3] for example, the years 1900 to 1999, in popular culture, constitute the 20th century.[4] (This is similar to the grouping of "0-to-9 decades" which share the 'tens' digit.)

To facilitate calendrical calculations by computer, the astronomical year numbering and ISO 8601 systems both contain a year zero, with the astronomical year 0 corresponding to the year 1 BC, the astronomical year -1 corresponding to 2 BC, and so on.[5][6]

While the century has been commonly used in the West, other cultures and calendars have utilized differently sized groups of years in a similar manner. The Hindu calendar, in particular, summarizes its years into groups of 60,[9] while the Aztec calendar considers groups of 52.[10]

The Institute's Museums, Libraries, and 21st Century Skills initiative underscores the critical role our nation's museums and libraries play in helping citizens build such 21st century skills as information, communications and technology literacy, critical thinking, problem solving, creativity, civic literacy, and global awareness.

Combining strengths in traditional and digital learning, libraries and museums are well-positioned to build the skills Americans need in the 21st century. Find out how your institution can get started.

At IMLS we have gathered success stories that demonstrate how libraries and museums are transforming their institutions and making a difference in their communities. See links to our latest stories below.

On October 8, 2010, President Obama signed the Twenty-First Century Communications and Video Accessibility Act (CVAA) into law. The CVAA updates federal communications law to increase the access of persons with disabilities to modern communications. The CVAA makes sure that accessibility laws enacted in the 1980s and 1990s are brought up to date with 21st century technologies, including new digital, broadband, and mobile innovations. The following are highlights of the law.

The greatest athlete of the 21st century? That's easy. It has to be Tom Brady, the quarterback of the greatest dynasty America's favorite sport has ever seen, a seven-time Super Bowl champ and five-time Super Bowl MVP. Yep. Tom Brady.

Except ... no ... LeBron James, right? Four-time NBA champ, four-time Finals MVP, four-time regular-season MVP, 20-time All-NBA, most points scored in NBA history. No athlete has dominated the public conversation like LeBron has. He has to be No. 1.

Except, what about Serena Williams? Winner of 23 Grand Slam titles, the Serena Slam (holding all four major titles at the same time) and four Olympic gold medals. And she got her final Grand Slam event win while pregnant, putting her career on hold while she was at her most dominant.

Except, if you are going to pick a tennis player, what about Roger Federer? He transformed an entire sport with his artistry, his chess game on the court, his blazing forehand. He won 20 Grand Slam titles and became the most beloved tennis player of all time. Gotta be Fed.

Hmm. Maybe this isn't so easy. We didn't even mention the Olympians: Usain Bolt and Michael Phelps and Katie Ledecky and Simone Biles. Or Kobe. Gotta throw Kobe Bryant into the discussion. Or Lewis Hamilton. Or Peyton Manning. Or Floyd Mayweather. Or Tiger. Geez, almost forgot about Tiger Woods.

Yes, ranking the top 100 most accomplished athletes since 2000 wasn't quite so easy after all -- but it sure was fun. Twenty-five years ago, the ESPN SportsCentury project ranked the top 100 North American athletes of the 20th century. Michael Jordan came in first, followed by Babe Ruth, Muhammad Ali, Jim Brown and Wayne Gretzky. (Ruth should have been No. 1, but hey, I'm a baseball writer.) We also ranked a horse: Secretariat came in at No. 35.

With so many transcendent athletes over the past 25 years, we thought it was time to do another ranking. I promise you there are no horses this time (sorry, American Pharoah). In considering the best athletes of the 21st century, however, we have expanded our choices beyond North America. ESPN editions from around the globe contributed to the nominations and voting process, as well as the individual sport list rankings that will follow.

Voters were instructed to consider only an athlete's performance since 2000. So, for Barry Bonds: He won seven MVP awards, but only four of those came after 2000, as did 317 of his 762 home runs. Or Ken Griffey Jr.: He played until 2010, but all of his best seasons came in the 1990s. Tiger won 13 of his 15 majors from 2000 on, so he's in good shape. Other athletes, such as Patrick Mahomes or Nikola Jokic or Shohei Ohtani, obviously have more greatness ahead of them, so we'll see how high their accomplishments so far get them on the list.

At the 2008 Beijing Olympics, Phelps earned a historic eight gold medals, more than any athlete in a single Olympics, while breaking world records in seven of his eight races. Throughout the Games, fans and members of the media tried to crack the code on what made Phelps -- who eventually won 23 Olympic gold medals and became the most decorated Olympian of all time -- so unbeatable. His mother, Debbie Phelps, was in Beijing, and often fielded their questions. Was it his size-14 feet? His extra-long arms? His breakfast regimen? "No," Debbie answered repeatedly. "It's his hard work." -- Alyssa Roenigk

There is little that Williams didn't achieve during her record-setting career, including winning 23 major titles. But it might have been her last one that was the most improbable. She needed to win one more Grand Slam to break the tie with Steffi Graf for most in the Open era (which began in 1968) -- a mark Williams said she had been "chasing for a really long time" -- and remained in the 2017 Australian Open draw even after finding out she was pregnant shortly before competition began. She was in peak Serena form, never dropping a set en route to a final showdown with her sister Venus. She defeated Venus to take sole ownership of the record.

Williams played in four more major finals after her return from maternity leave and a complicated childbirth. She didn't win another title. "The way I see it, I should have had 30-plus Grand Slams," Williams wrote in Vogue in a 2022 essay announcing her impending retirement. "I didn't get there ... But I showed up 23 times, and that's fine. Actually it's extraordinary." -- D'Arcy Maine

Messi winning the World Cup in Argentina in 2022 was perhaps the biggest Hollywood ending that soccer has ever seen. After losing the 2014 final, it looked like it would never happen for Messi, who had won everything else in the game for club and country, but the crowning moment of his career finally arrived at age 34. He scored twice in the final as Argentina beat France on penalties, sparking an outpouring of emotion and celebrations around the globe. "This guy transcends rivalries -- even between Brazil and Argentina," Brazil legend Ronaldo said. "I saw Brazilians and people all over the world rooting for Messi. It's a fitting finale for a genius who has marked an era." -- Sam Marsden

The "48 special" game happened 17 years ago this spring. That's when James scored 29 of the last 30 points for the Cleveland Cavaliers in a double-overtime upset Game 5 road win against the Detroit Pistons in the Eastern Conference finals. The 48-point game was a mesmerizing performance that stands as one of the classic games of this century ... and it probably doesn't even rank in the top 10 of James' playoff performances. It might not be one of his top three conference finals games. This is what James' greatness rests on: No one has ever been this good for this long. That long-ago night in the Palace of Auburn Hills is merely one of 29 40-point games James has in the playoffs alone.

That win paved the way to his first Finals, starting a run of 10 appearances in 14 years. During that stretch he won four NBA titles, four MVPs and four Finals MVPs with three different teams, as well as two Olympic gold medals. He also won at least one road game in 29 consecutive playoff series. He has scored in double figures in 1,222 consecutive regular-season games -- the last time he didn't, his son Bronny, now his Laker teammate, was 2 years old. Volume isn't a vogue way to measure achievement in the NBA anymore, and it lends credence to those who want to push James down all-time lists. It's the only side of the argument to take against James, who has essentially renamed the NBA's record book for himself. -- Brian Windhorst
