Q: Editor's note: Ben Chavis is the co-author with Carey Blakely of "Crazy Like A Fox: One Principal's Triumph in the Inner City." Chavis received his doctorate in education and philosophy from the University of Arizona and served as principal of American Indian Public Charter School for seven years. Chavis has also worked as a real estate investor. Currently, he is replicating the model he established at American Indian Public Charter School in various schools throughout the U.S. and Canada. Educator Ben Chavis says money isn't enough to improve schools run by incompetent administrators. (CNN) -- Teachers unions and politicians are constantly claiming that K-12 public schools need more money in order to produce good academic results. But does the data support the argument that our schools need more money to succeed? The Oakland Unified School District had a budget of $602 million for the 2008-2009 school year, according to Katy Murphy, an education reporter with the Oakland Tribune. That budget, which includes $77 million spent on consultants, means that the district spends an average of $16,270 per student! What have we, the public taxpayers, received for our exceptionally generous financial support of the Oakland public schools? According to the California Department of Education, the district's reported 2008 California Standardized Test scores show: . 1. Of 707 eighth- and ninth-graders who took the California Standard test for general math: 1 percent tested advanced, 5 percent tested proficient and 94 percent failed by testing below grade level.  See details about K-12 schools, teachers » . 2. Of 2,506 ninth- and 10th-grade students who took the California Standards test in algebra: 0 percent tested advanced, 3 percent tested proficient and 97 percent failed the test. How is it possible for a public school system to so liberally spend more than half a billion dollars and still fail to educate 94 percent or more students of all racial backgrounds? Does anyone believe providing more money to these public school systems will enhance these students' academic performance in mathematics? During my principalship at American Indian Public Charter School, we spent less than $8,000 per student, proving that schools did not need more money. We served a student population that is on average 98 percent minority, with 97 percent receiving free or reduced-price lunch and many who are non-English speakers and from single-parent families. AIPCS students spend three to four hours a day working on mathematics and English-language arts. In 2009, they excelled in academics, physical fitness and any standardized test that they were given. The hard work of these students and staff has paid off with virtually all of our eighth-graders testing advanced in algebra, including 100 percent of our eighth-grade black students, Mexican-American students and American Indian students. Before I became its principal, people called American Indian Public Charter School the zoo. The neighbors hated it. They couldn't stand the behavior of the students, who, with little supervision or control, wreaked havoc in the area. Unfortunately, the students who decided to attend the school did not receive the academics and structure they so direly needed. The school was in many ways a failure, a joke, a sham. When I took over as principal in 2000, it was the worst middle school in Oakland. I told the board I would take the job only if they let me go my own way and do what I thought was best. I implemented a golden rule at American Indian Public Charter School for staff, students and families: If you act like a winner, you'll be treated like a winner. If you act like a fool, you'll be treated like a fool. The charter school is now one of the top-scoring schools in the state and is nationally recognized. The United States spends more money on public education than any other country in the world. Yet, we still have a secondary public education system that ranks with Third World countries in preparing our children in English-language arts, mathematics, science and social studies. Washington, D.C.; Detroit, Michigan; Los Angeles, California; Kansas City, Missouri; and numerous other cities throughout the United States are producing the same poor academic results at an extraordinary cost to the taxpayer and a tremendous academic loss to our students and country. I believe all the money in the world would not be enough to improve schools run by incompetent public school administrators. We need proven leaders who can prepare our children to be competitive members in a free-market society. The American public has been conned into believing that public schools need more money. Have you ever met a public school administrator who said they have enough money? President Obama is moving in the "right" direction by reforming public schools to be held responsible to the American public in return for more money. It's very clear that most Americans want to ensure that accountability be attached to the stimulus money that is being awarded to all institutions, including public schools. Next time you hear school officials or politicians begging for more money, ask them how large the district's budget is and how many students are enrolled in their district. Then you do the math. After all, it's your money they want to take. The opinions expressed in this commentary are solely those of Ben Chavis.

Q: Past, present and future came together on a thunderstorm-filled Sunday, as President Barack Obama received an honorary doctorate and gave the commencement speech at historically black, all-male Morehouse College, where the Rev. Martin Luther King and many other prominent African-Americans spent their formative years. After opening with several one-liners, and more smiles than we've seen from him in the damage-control-filled recent weeks, Obama delivered a serious message to the class of 2013. During a speech rife with both personal and historical references, the president invoked a past full of challenges, often resulting from racism, but noted that African-Americans need to break free from that past to succeed in a globally competitive economy. "I understand that there's a common fraternity creed here at Morehouse: 'Excuses are tools of the incompetent, used to build bridges to nowhere and monuments of nothingness,'" Obama said. "We've got no time for excuses -- not because the bitter legacies of slavery and segregation have vanished entirely; they have not. Not because racism and discrimination no longer exist; we know those are still out there. It's just that in today's hyperconnected, hypercompetitive world, with millions of young people from China and India and Brazil -- many of whom started with a whole lot less than all of you did -- all of them entering the global workforce alongside you, nobody is going to give you anything that you have not earned," he said. Opinion: What Obama must say to African-American grads . "Nobody cares how tough your upbringing was. Nobody cares if you suffered some discrimination. And moreover, you have to remember that whatever you've gone through, it pales in comparison to the hardships previous generations endured -- and they overcame them. And if they overcame them, you can overcome them, too," he said. Morehouse valedictorian Betsegaw Tadele praised Obama for setting a strong example. "There is no impossible. There is no unbelievable. There is no unachievable, if you have the audacity to hope," Tadele said, paraphrasing the name of the president's 2006 book, "The Audacity of Hope." Following Tadele -- whom Obama jokingly called "a skinny guy with a funny name" -- Obama reflected on how being an African-American has affected his personal journey. "Whatever success I have achieved, whatever positions of leadership I've held, have depended less on Ivy League degrees or SAT scores or GPAs, and have instead been due to that sense of connection and empathy, the special obligation I felt, as a black man like you, to help those who need it most; people who didn't have the opportunities that I had -- because there, but for the grace of God, go I. I might have been in their shoes.  I might have been in prison. I might have been unemployed. I might not have been able to support a family. And that motivates me," the president said. Big-name college commencement speakers of 2013 . The president's repeated mention of connection to the black community comes after blunt criticism from Morehouse alumnus Kevin Johnson, a pastor from Philadelphia, who criticized Obama in an April 14 editorial in the Philadelphia Tribune, calling him "a president for everyone, except black people." Johnson gave a baccalaureate sermon on Saturday as part of Morehouse's graduation weekend. The president's speech on Sunday was well-received, though the crowd had to brave some thunder and lightning and endure pouring rain. One awkward silence came when Obama slightly deviated from his prepared remarks. He was expected to say, "Be the best husband to your wife, or boyfriend to your partner." However, instead, he said "Be the best husband to your wife, or your boyfriend, or your partner," eliciting some clearly confused responses from the crowd. Later, he noted that Morehouse men can set examples for other groups that have been subjected to discrimination: Hispanics, gays and lesbians, Muslims, and women. "It is not just the African-American community that needs you. The country needs you. The world needs you.  As Morehouse men, many of you know what it's like to be an outsider; know what it's like to be marginalized; know what it's like to feel the sting of discrimination.  And that's an experience that a lot of Americans share," he said. Obama said his job, as president, is to advocate for policies that generate more opportunity for everyone, and he implored the Morehouse grads -- and all Americans -- to "advocate for an America where everyone has a fair shot in life." "There are some things, as black men, we can only do for ourselves.  There are some things, as Morehouse men, that you are obliged to do for those still left behind.  As graduates -- as Morehouse men -- you now wield something even more powerful than the diploma you are about to collect.  And that's the power of your example," he said. Students scarred by war earn college degrees . Obama finished his speech with another message not just to the newly minted Morehouse grads, but to all Americans -- a message based on Martin Luther King's refusal to be afraid. "That's what being an American is all about. Success may not come quickly or easily. But if you strive to do what's right; if you work harder and dream bigger; if you set an example in your own lives and do your part to help meet the challenges of our times, then I am confident that, together, we will continue the never-ending task of perfecting our union," he said. And despite lots of big-picture talk about success and giving back, Obama made it clear that without appropriate focus on those closest to you, big-picture accomplishments mean little. "Everything else is unfulfilled if we fail at family -- if we fail at that responsibility. I know that when I am on my deathbed someday, I will not be thinking about any particular legislation I passed. I will not be thinking about a policy I promoted. I will not be thinking about the speech I gave. I will not be speaking about the Nobel Prize I received.  I will be thinking about that walk I took with my daughters. I'll be thinking about a lazy afternoon with my wife.  I'll be thinking about sitting around the dinner table, and seeing them happy and healthy and knowing they were loved. And I'll be thinking about whether I did right by all of them."

Q: A Texas company says it has made the first metal gun using a 3-D printer, taking the debate over people's emerging ability to create their own firearms to a new level. Solid Concepts, a specialty manufacturing company, said in a blog post it has fired more than 50 rounds from the handgun, even hitting a few bull's-eyes at more than 30 yards. The pistol is a version of an M1911, a handgun designed by John Browning and first used widely in the latter stages of combat stemming from the Philippine-American War. It's built from 33 mostly stainless-steel parts and has a carbon-fiber handgrip carved with a laser. "The 3-D-printed metal gun proves that 3-D printing isn't just making trinkets and Yoda heads," the company said in the blog post. Solid Concepts went out of its way Friday to point out that producing the metal gun isn't meant to advance a trend that worries law enforcement and some politicians. As 3-D printers become more widespread and affordable, some envision a near future in which criminals can crank out untraceable weapons without having to leave their homes. "Let me start out by saying one, very important thing: This is not about desktop 3-D printers," Alyssa Parkinson, a spokeswoman for the company, wrote in the blog post. The metal gun wasn't a move toward making firearms with a 3-D printer cheaper or more accessible, she wrote. Basic 3-D printers, such as the MakerBot Replicator 2, can be bought for around $2,000. But Solid Concepts used a specialized, high-end printer whose cost would be out of reach of most people. "The industrial printer we used costs more than my college tuition (and I went to a private university)," Parkinson said. "And the engineers who run our machines are top of the line; they are experts who know what they're doing and understand 3-D printing better than anyone in this business." Solid Concepts wanted to show that 3-D printing is more than just hobbyists churning out plastic doodads -- it's a viable option for serious commercial use. "It's a common misconception that 3-D printing isn't accurate or strong enough, and we're working to change people's perspectives," Kent Firestone, a vice president at the company, said in a statement. In May, a nonprofit group, also from Texas, stirred far more controversy when it posted a video of the live firing of a plastic handgun created with a 3-D printer. Cody Wilson, a 25-year-old self-described anarchist, posted instructions on how to make the gun online through his nonprofit group, Defense Distributed. Those instructions were taken down after the U.S. State Department sent the group a cease-and-desist letter. The group's website was shut down shortly afterward. Solid Concepts is a licensed firearm manufacturer. It said one use for its new capabilities with 3-D printers may be selling replacement parts for handguns.
