K-12 teachers are faced with a question many likely thought they'd never have to ask: How often during the school day do my students need to see me and when?

The new question-of-the-week is: What are your best classroom-management tips?

Experimenting with new types and arrangements of furniture can radically change your students' classroom experience, writes Julia Cin.

Dr. Debbie Silver, Dr. PJ Caposey, Serena Pariser, Timothy Hilton, Dr. Beth Gotcher, Paula Mellom, Rebecca Hixon, and Jodi Weber offer their commentaries on how best to handle classroom management.

Cindy Garcia, Gianna Cassetta, Amanda Koonlaba, Ed.S., Chelonnda Seroyer, Dennis Griffin Jr., Janice Wyatt-Ross, Barry Saide, and Dr. Vance Austin contribute their classroom-management suggestions.

The video-sharing platform is a huge hit with teens and some teachers are beginning to integrate it into their lessons. But cyberbullying and data privacy are big concerns, experts say.

Popularized by social media, new classroom arrangements are all the rage in K-12. But experts and educators caution there is more to it than just moving desks around.

When teachers use more praise and fewer reprimands in the classroom, it seems to help students stay on-task and behave better, according to a new study.

As an attempt to mitigate a persistent school supply problem, New Mexico plans to give some 23,000 teachers prepaid gift cards for use on classroom materials. One local union calls it a distraction from larger funding issues.

The money is better spent on sincere and hardworking teachers.

Clinical decision support systems offer a way to help physicians use evidence-based guidelines for screening. Screening patients for common developmental, psychosocial, and behavioral issues informs the clinical decision-making process and may improve patient outcomes.

The Child Health Improvement through Computer Automation system, a clinical decision support system and an electronic medical record, is able to effectively screen patient families in the waiting room by using a tailored questionnaire. The study reveals positive screening rates for identifiable risks in a very large representative urban population by using Child Health Improvement through Computer Automation’s questionnaire.

Inadequate sleep in childhood is associated with poor mental and physical health. Numerous cross-sectional studies reveal associations between television viewing and the presence of a bedroom TV and inadequate sleep in older children and adolescents, but longitudinal research is limited.

More TV viewing, and, among racial/ethnic minority children, bedroom TV, were associated with shorter sleep from infancy to midchildhood. These results raise the possibility that interventions to reduce TV could improve children’s sleep. (Read the full article)

The single-family room (SFR) NICU is a major response to improve care and reduce developmental morbidity in preterm infants. However, no studies have examined how and why this model is associated with changes in medical and neurobehavioral outcome.

This study shows improved medical and neurodevelopmental outcome in infants hospitalized in the SFR model of care. More important, improvements occurred specifically in relation to increases in maternal involvement and developmental support afforded by the SFR environment. (Read the full article)

Quality improvement (QI) studies generally do not account for concurrent trends of improvement and it is difficult to distinguish the impact of a multihospital collaborative QI project without a contemporary control group.

A multihospital collaborative QI model led to greater declines in hypothermia and invasive ventilation rates in the delivery room compared with an individual NICU QI model and NICUs that did not participate in formal QI activities. (Read the full article)

Integrating technology requires a significant investment of time and money, but the resources are well-spent if the focus is improving instruction, writes educational consultant Matthew Lynch.

About two dozen teachers from across the country spent a week wrestling with questions about how to remember the Confederacy.

The "elephant in the room" has everything to do with technology but is not really about technology at all.

Aristotle, the famous Greek philosopher who lived four centuries before Christ, proposed the scientific theory of horror vacui. Based on his observations, he concluded that nature fills every empty space with something, even if it is only air. In his works Gargantua and Pantagruel, the Renaissance priest, doctor and scientist Rabelais popularized this idea with the phrase Natura abhorret vacuum (“nature abhors a vacuum”). Where there is a void, either mass or energy rushes in to occupy the empty space. In truth, this theory applies not merely to physics, but to life.

For the last thirty years, the secularization of culture and the banishing of God from the public forum have created a great religious void. More and more Americans have been abandoning the practice of religion. Since 1990, the number of Americans who claim no religious affiliation has tripled from eight percent to twenty-two percent. 

Today there are about five million fewer mainline Protestants and three million fewer Catholics than there were ten years ago. For every new convert to Catholicism, six others leave the Church. Young people between the ages of 18 and 30 are much less interested in religion than their parents. As Alan Cooperman, the director of religion research for the Pew Research Center, has observed, “the country is becoming less religious as a whole, and it’s happening across the board.”

Nonetheless, the human person is innately religious. More than just being a material creature on the same level as irrational animals, the human person has reason and is always in search of meaning. “Nature abhors a vacuum.” And, so into the void created by abandoning religion as a source of meaning, other forms of discovering meaning have rushed in. 

In an attempt to respond to the spiritual dimension of human life, some people are turning to New Age beliefs. New Age adherents, now nearly one-fourth of the population, have replaced the personal God of revelation with a spiritual energy that animates the cosmos. They are making use of crystals, tarot cards, astrology, psychics, and even yoga as a spiritual exercise to tap into this impersonal energy in order to manage their lives and find self-fulfillment. 

For New Age adherents, there is no absolute truth. All beliefs are of equal value. And, since they deny the existence of sin, they do not accept the need for a Redeemer. At best, New Age adherents trade the transcendental for the immanent, the spiritual for the physical. At worse, they reject God and unwittingly fall into the hands of the Adversary. 

And, then there are others who reject God and consciously choose to turn to one form or another of the occult. It is astounding to realize that there are almost 1.5 million people who are involved in Wicca, a pagan form of witchcraft. Ever since the Garden of Eden and our first parents’ sin of attempting to be like God, people have been looking for ways to have the same knowledge and power as God himself. Today there are more witches than Presbyterians, more people involved in the occult than there are Muslims in the United States. 

The more individuals extol themselves as self-sufficient and exalt reason over faith, they turn from God and enthrone Satan. Attempting to control their lives through the use of the occult, they hand themselves over to Satan who uses them to destroy the peace and harmony God plans for us. Satan is the great deceiver. He makes people believe that they have absolute control of their lives. As Archbishop Fulton Sheen once said, “[Satan’s] logic is simple: if there is no heaven there is no hell; if there is no hell, then there is no sin; if there is no sin, then there is no judge, and if there is no judgment, then evil is good and good is evil.”

It would be foolish to close our eyes to the unmistakable increase of the devil’s activity in our society. Lack of civility. Hate speech. The tearing down of people’s good name. The blood shed on our streets. The breakdown of family life. The widespread extolling of vices contrary to the gospel. The delight in exposing the sins of others. Abuse in all its forms. Abortion. The persecution of the Church. All these are born of anger, hatred, envy, pride, greed and lust. They cause division and are the fingerprints of the Evil One.

On the day after his election to the papacy, Pope Francis shocked the cardinals who had placed him on the Chair of Peter. He said, “Whoever does not pray to God, prays to the devil. When one does not profess Jesus Christ, one professes the worldliness of the devil.” The Pope courageously acknowledged the reality of Satan that day and many other times thereafter. And the Pope provided the only way to banish the devil from our midst: professing faith in Jesus. Professing our faith means quite simply staying close to Jesus within the Church, attending Mass at least each Sunday and Holy Day, receiving the sacraments and practicing charity. In other words, the only permanent antidote to evil in the world is the presence of God who leaves in us no room for evil.

Key Findings:  Nearly 100% of SoCs are mixed-signal to some extent.  Every one of these could benefit from the use of a metrics-driven unified verification methodology for mixed-signal (MD-UVM-MS), but the modeling step is the biggest hurdle to overcome.  Without the magical models, the process breaks down for lack of performance, or holes in the chip verification.

In the last installment of The Low Road, we were at the mixed-signal verification party. While no one talked about it, we all saw it: The party was raging and everyone was having a great time, but they were all dancing around that big elephant right in the middle of the room. For mixed-signal verification, that elephant is named Modeling.

To get to a fully verified SoC, the analog portions of the design have to run orders of magnitude faster than the speediest SPICE engine available. That means an abstraction of the behavior must be created. It puts a lot of people off when you tell them they have to do something extra to get done with something sooner. Guess what, it couldn’t be more true. If you want to keep dancing around like the elephant isn’t there, then enjoy your day. If you want to see about clearing the pachyderm from the dance floor, you’ll want to read on a little more….

Figure 1: The elephant in the room: who’s going to create the model?

 Whose job is it?

Modeling analog/mixed-signal behavior for use in SoC verification seems like the ultimate hot potato.  The analog team that creates the IP blocks says it doesn't have the expertise in digital verification to create a high-performance model. The digital designers say they don’t understand anything but ones and zeroes. The verification team, usually digitally-centric by background, are stuck in the middle (and have historically said “I just use the collateral from the design teams to do my job; I don’t create it”).

If there is an SoC verification team, then ensuring that the entire chip is verified ultimately rests upon their shoulders, whether or not they get all of the models they need from the various design teams for the project. That means that if a chip does not work because of a modeling error, it ought to point back to the verification team. If not, is it just a “systemic error” not accounted for in the methodology? That seems like a bad answer.

That all makes the most valuable guy in the room the engineer, whose knowledge spans the three worlds of analog, digital, and verification. There are a growing number of “mixed-signal verification engineers” found on SoC verification teams. Having a specialist appears to be the best approach to getting the job done, and done right.

So, my vote is for the verification team to step up and incorporate the expertise required to do a complete job of SoC verification, analog included. (I know my popularity probably did not soar with the attendees of DVCON with that statement, but the job has to get done).

It’s a game of trade-offs

The difference in computations required for continuous time versus discrete time behavior is orders of magnitude (as seen in Figure 2 below). The essential detail versus runtime tradeoff is a key enabler of verification techniques like software-driven testbenches. Abstraction is a lossy process, so care must be taken to fully understand the loss and test those elements in the appropriate domain (continuous time, frequency, etc.).

Figure 2: Modeling is required for performance

AFE for instance

The traditional separation of baseband and analog front-end (AFE) chips has shifted for the past several years. Advances in process technology, analog-to-digital converters, and the desire for cost reduction have driven both a re-architecting and re-partitioning of the long-standing baseband/AFE solution. By moving more digital processing to the AFE, lower cost architectures can be created, as well as reducing those 130 or so PCB traces between the chips.

There is lots of good scholarly work from a few years back on this subject, such as Digital Compensation of Dynamic Acquisition Errors at the Front-End of ADCS and Digital Compensation for Analog Front-Ends: A New Approach to Wireless Transceiver Design.

Figure 3: AFE evolution from first reference (Parastoo)

The digital calibration and compensation can be achieved by the introduction of a programmable solution. This is in fact the most popular approach amongst the mobile crowd today. By using a microcontroller, the software algorithms become adaptable to process-related issues and modifications to protocol standards.

However, for the SoC verification team, their job just got a whole lot harder. To determine if the interplay of the digital control and the analog function is working correctly, the software algorithms must be simulated on the combination of the two. That is, here is a classic case of inseparable mixed-signal verification.

So, what needs to be in the model is the big question. And the answer is, a lot. For this example, the main sources of dynamic error at the front-end of ADCs are critical for the non-linear digital filtering that is highly frequency dependent. The correction scheme must be verified to show that the nonlinearities are cancelled across the entire bandwidth of the ADC. 

This all means lots of simulation. It means that the right level of detail must be retained to ensure the integrity of the verification process. This means that domain experience must be added to the list of expertise of that mixed-signal verification engineer.

Back to the pachyderm

There is a lot more to say on this subject, and lots will be said in future posts. The important starting point is the recognition that the potential flaw in the system needs to be examined. It needs to be examined by a specialist.  Maybe a second opinion from the application domain is needed too.

So, put that cute little elephant on your desk as a reminder that the beast can be tamed.
