"This interactive tutorial will teach you how to use the sequent calculus, a simple set of rules with which you can use to show the truth of statements in first order logic. It is geared towards anyone with some background in writing software for computers, with knowledge of basic boolean logic."

"Sir Ken Robinson provides the closing statement for the LWF 12 conference under the theme "leading a learning revolution"."

Superb and inspirational. "Bret Victor invents tools that enable people to understand and create. He has designed experimental UI concepts at Apple, interactive data graphics for Al Gore, and musical instruments at Alesis."

"Anyway, I think I have a bit of a unique perspective. I've seen MIT admissions from the perspective of the applicant, a student, a teacher, and now as an alumnus conducting interviews of prospective students. The fact that you mentioned MIT specifically really made me feel like I should take the time to produce a good response!"

Great talk and good QA.

"Whilst heading up the Manhattan Project during World War II, theoretical physicist Robert Oppenheimer quickly became aware of a promising young physicist by the name of Richard Feynman. Sensing that Feynman would be incredibly valuable at UC Berkeley come the end of the war, Oppenheimer wrote the following letter to then chairman of its physics department, Raymond Birge. To label the letter a glowing recommendation would be an understatement, but even so, and despite Oppenheimer's efforts, Feynman turned down the subsequent offer."

Full courses. Short Videos. Free for everyone.

"This is the first of what I hope will be a long series of posts aimed at providing back-up to first-year Cambridge mathematicians. This may seem a strange thing to do, since the Cambridge system of supervisions (classes taught on a one-to-two basis, usually discussing questions set by lecturers) already provides an excellent back-up to lectures. Do Cambridge undergraduates, who already have closer attention than in any other university I know about, really need even more help?"

Good resources in the first comment.

"One of the most frequent questions we get in various physics forums and IRC physics channels (besides the annoying ”can anything travel faster than c?”) is the process and background of being a physics major. Often, we have students asking what are the requirements of obtaining a physics degree, and what can one do with such accomplishments.

I am hoping that, in a series of postings on this topic, we get to go over and demystify the whole process of what one can expect as a physics major in college, all the way to going through a Ph.D program, and even beyond that in the land of postdoctoral work and employment. This is not as easy as it sounds, especially considering the wide-ranging educational systems we have throughout the world. So in most cases, the perspective I will tend to have the most understanding with is the US educational system. This is where someone from another country can come in and contribute their experiences and wisdom...."

Another essay on teachings of mathematics.

"Background: I recently finished my bachelor's degree in computer science at Berkeley. Although it may be a bit late, I am just now getting interested in learning more about statistics and "data science." Unfortunately, I don't have much of a math background (only took up to Linear Algebra) and the required probability/discrete math course for CS. Although I started working, I have the option of enrolling in an MS CS program in January. What courses should I be looking at and will a MS in Statistics be more useful? If so, is it possible to get into an MS in Statistics without a strong math background? I will probably be looking into taking machine learning and data visualization." Great comprehensive answer...

"Let's say, in the near future, tens of millions of students start learning math using online computer software. Our logs fill with a massive new data stream, millions of students doing billions of exercises, as the students work."

"A reading protocol is a set of strategies that a reader must use in order to benefit fully from reading the text. Poetry calls for a different set of strategies than fiction, and fiction a different set than non-fiction. It would be ridiculous to read fiction and ask oneself what is the author's source for the assertion that the hero is blond and tanned; it would be wrong to read non-fiction and not ask such a question. This reading protocol extends to a viewing or listening protocol in art and music. Indeed, much of the introductory course material in literature, music and art is spent teaching these protocols."

"Introduction. In the broad field of computer science, one of the few sources of fundamental concepts that help us to characterize and to think about problems across its subdisciplines is that of programming languages. The field of programming languages provides us with the best understood mechanisms we have for rigorously specifying and reasoning about software systems. Moreover, the concepts that have been developed for characterizing programming languages have provided us with insights and mechanisms for reasoning about the behaviors of all computations. By failing to expose computer science majors to these concepts, we are depriving them of critical knowledge of their chosen field, making them less effective in their profession, whether they become software developers or researchers (or both). In this paper, I discuss some of the most critical topics in programming languages that every computer science major should learn, and why they are important."

"The linked document is the first public release of a document discussing the value of programming languages principles for undergraduate CS majors. The intended audience is computer scientists who are not specialists in programming languages. Please leave comments on how well you believe it meets its goals and with suggestions for improvements." // Abstract: "Undergraduate students obtain important knowledge and skills by studying the pragmatics of programming in multiple languages and the principles underlying programming language design and implementation. These topics strengthen students' grasp of the power of computation, help students choose the most appropriate programming model and language for a given problem, and improve their design skills. Understanding programming languages thus helps students in ways vital to many career paths and interests." (via http://lambda-the-ultimate.org/node/3990 )

"Undergrad AI should both give students an appreciation for AI as well as a glimpse of important research problems in the field. More and more, this means teaching the theory and practice of optimization. When IBM ads tell us they want a “smarter planet”, this is what they’re talking about."

"In this post, I speculated on what I might put into my automata theory course. That prompted Subrahmanyam Kalyanasundaram, a PhD student at Georgia Tech, who was teaching Automata theory this spring, to begin a private correspondence with me. Now that both of our courses are over we can tell you what happened."

"Dr. Jim Davies presents a talk at Carleton University on innovative teaching strategies that involve assignments that not only educate the students doing them, but contribute to the greater educational and scientific communities. "

"Today's math curriculum is teaching students to expect -- and excel at -- paint-by-numbers classwork, robbing kids of a skill more important than solving problems: formulating them. At TEDxNYED, Dan Meyer shows classroom-tested math exercises that prompt students to stop and think."

"Sometimes you learn a theorem in your academic career far later than you should have. Here are some examples."

"U biti, podaci govore obrnuto: po broju „kvalitetnih“ učenika lošije smo prošli nego po prosječnom uspjehu hrvatskih srednjoškolaca na PISA testiranju. Naime, najbolji rezultati na PISA testu znače da je učenik sposoban svoje znanje primjeniti u praksi. Takvi učenici u PISA istraživanju se posebno analiziraju pod imenom „top performers“. **Oni su iznimno važni jer upravo takvi pojedinici imaju potencijal doprinjeti neproporcionalno više društvu nego li ostali.** Ukratko, PISA istraživanje je pokazalo da smo „trećerazredna“ zemlja po broju kvalitetnih učenika."

Među braindead komentarima... "Ah, vidim jako puno stvari ovdje na koje se osjecam pozvan da reagiram. Prvo da se predstavim: ja sam bivsi bivsi natjecatelj i olimpijac iz informatike (sada sam na faksu... doticna natjecanja su rezervirana za srednjoskolce). Pomagao sam HSIN-u u izradi raznih natjecanja (zupanijsko, drzavno, HONI), te nisam izravno ukljucen u navedeno otvoreno pismo, iako znam puno ljudi koji to jesu."

"U posljednje se vrijeme u raznim našim javnim glasilima moglo pročitati više kritičkih osvrta na nastavu i učenje matematike u našim školama. Nažalost, ti su tekstovi površni, uglavnom tmurno obojeni, nerijetko destruktivni i tragovi koje ostavljaju za sobom neće doprinijeti boljitku naše škole, posebice neće biti poticajni za učenje matematike. Ovom je pak tekstu zamisao dati jedan pogled „iznutra“, onako kako problem vidi jedan iskusni nastavnik matematike. " ... "Jedan od problema učenja matematike jest predugo trajanje opismenjavanja. No, kao što bez jezične pismenosti nema suvisle pismene komunikacije ni lijepog literarnog štiva, tako nema ni znanja, pa onda ni primjene matematike bez solidne matematičke pismenosti. Usmjeriti nastavu matematike isključivo u primjere njezine konkretne, nerijetko sasvim banalne primjene, neprihvatljiva je krajnost jednako tako kao što je neprihvatljivo nastavu matematike svesti na puko manipuliranje apstraktnim činjenicama. "

"Sažetak. Međunarodna matematička olimpijada koja danas predstavlja svjetsko prvenstvo učenika srednjoškolaca u rješavanju zahtjevnih matematičkih problema bliži se svojoj pedesetoj godišnjici. U ovom članku dan je kratki povijesni pregled, opis natjecanja i osvrt na neka druga matematička natjecanja."

"Otkad je pred nekoliko godina Agencija za "odgoj" i "obrazovanje" preuzela dodatno i organizaciju Natjecanja iz informatike u Hrvatskoj, dogodilo se nekoliko apsurdnih stvari -- stvari koje su proveli ljudi koji vrlo očito nemaju kontakta s našim izvrsnim natjecateljima, među najboljima u svijetu. Imao sam sreću postati student malo prije ovih događanja, kako ne bih na vlastitoj koži proživljavao ova previranja." Ivan Vučica

Dario Hrupec o cijeloj priči vezanoj za Paara.

"A to da u Hrvatskoj ima malo ljudi koji žele javno osuditi svoje kolege kada bivaju šarlatani, štetočine i crackpoti, to mi je poznato, čak i sa sigurne udaljenosti od 2000 kn. Općenito, akademski "ugled" u Hrvatskoj je nešto što se olako stječe, a potom mnogi ljudi misle da kad se jednom stekne da ga nije moguće izgubiti ni desetljećima nerada, štetočinstva ili šarlatanije. Nije npr. moguće napisati (maksimalno, neoborivo argumentiranu) negativnu recenziju znanstvenog opusa osobe koja zadnjih dvadeset godina nije radila ništa ili je radilia loše bez da se digne dreka "kako se to usuđujete blatiti uglednog profesora/profesoricu" i bez da vam odmah idu odgonetavati "s kim je/čiji je/tko ga štiti/što hoće". Mogućnost da je odgovor "ni s kim/ničji/nitko/hoće da hrvatska znanost, visoko školstvo i država općenito budu bolji ili barem manje jadni" je nešto što njihovim mozgovima ispranima korupcijom, nepotizmom i zakulisnim igrama uopće ne pada na pamet." B.L.

"It is quite natural for academics who are continuously told to ”publish or perish” to want to always create something from scratch that is their own contribution. This book is an for me experiment in ”re-mixing” an book titled Think Python: How to Think Like a Computer Scientist written by Allen B. Downey, Jeff Elkner and others." ... " I hope that this book serves an example of why open materials are so important to the future of education..."

"U ovom ću dnevniku iznijeti pet kratkih pričica iz hrvatske akademske stvarnosti, koja je nedavno došla pod svjetlo reflektora u akciji 'Indeks' " --- 10.2008.

"Ako se institucije rangiraju prema normiranoj kvaliteti časopisa u kojima se objavljuje, sveučilište pada na 1834. mjesto u svijetu. Ako se rangira po normiranoj citiranosti članaka, pada na 1881. mjesto. Oba su ta plasmana ispod gomile razmjerno opskurnih sveučilišta iz Kine, Indije ili Turske, pa i nekih afričkih zemalja. Poznata je činjenica da su članci sa Sveučilišta u Harareu u Zimbabveu u prosjeku citiraniji i objavljuju se u kvalitetnijim časopisima nego oni zagrebačkog sveučilišta - ustvrdio je Lenhard."

"Ja Vam tvrdim da će većina s diplomom matematike ili fizike na PMF-u uz kratku obuku biti bolji ekonomisti nego oni s diplomom ekonomskog fakulteta u Zagrebu." BL. Zašto je mnogima teško u to vjerovati :-) Prvo bi trebali popraviti sustav vrijednosti...

"Bolonjski proces je potpuno besmislen i promašen ako se ne dogodi "integracija sveučilišta", tj. ako umjesto labave nakupine potpuno autonomnih institucija (fakulteta) ne nastanu prava sveučilišta. Bez toga je ideja interdisciplinarnosti potpuno neprovediva - odmah se postavlja apsurdno pitanje "institucije - nositelja". " prof. H. K. // Još uvijek nitko ne rješava osnovne probleme :-(

"Clustering of experts in actual institutions will continue, for the same reason that high-tech expertise congregates in Silicon Valley and elsewhere. But the actual progress of science will be driven by ever more immersive technology where propinquity is irrelevant. Traditional universities will survive insofar as they offer mentoring and personal contact to their students. But it's less clear that there will be a future for the 'mass university' where the students are offered little more than a passive role in lectures (generally of mediocre quality) with minimal feedback. Instead, the Internet will offer access to outstanding lectures — and in return will offer the star lecturers (and perhaps the best classroom teachers too) a potentially global reach." MARTIN REES

"I am teaching graduate complexity theory this spring, and I have some ideas on how to structure the class in a different way than usual. For starters I want to list what the students should know. I want them to know certain material “cold.” I want them to know, for example, the exact definition of the complexity class {\mathsf{BPP}}, know the statement of Toda’s Theorem, and know the proof of Savitch’s Theorem." Nice list and discussion below.

My first question on MathOverflow :-) I'm satisfied with responses.

"In December 2009, the UCT Algorithm Circle help a training camp sponsored by the CHPC. The camp ran for 5 days, with 15 of the top kids in the country invited. Below is a summary of the lectures given, along with slides, tutorials and videos of the lectures."

"This participatory seminar focuses on the knowledge and skills necessary for teaching science and engineering in higher education. This course is designed for graduate students interested in an academic career, and anyone else interested in teaching. Readings and discussions include: teaching equations for understanding, designing exam and homework questions, incorporating histories of science, creating absorbing lectures, teaching for transfer, the evils of PowerPoint, and planning a course. The subject is appropriate for both novices and those with teaching experience."

"Today’s the day—the 150th anniversary of the publication of Charles Darwin’s On the Origin of Species, the most famous work of the great 19th century naturalist. And to mark the occasion, the Darwin Manuscripts Project is uploading Darwin’s original drafts—10,000 pages worth—into an online archive. Look for the material to go online later today."

"Kolega u paralelnoj raspravi savršeno je pogodio timing stavljanjem linka na Minchinovu pjesmu.

Recenzija: Teorija neobrazovanosti (zablude društva znanja) * "To potpuno nepostojanje suvisle kritike, suvislih političkih opcija, samo potvrđuje stanje barbarstva o kojemu smo govorili na početku: mi smo društvo blesana koje će ova reforma, po svoj prilici, dotući do kraja zato jer nas vode ljudi beskralježnjaci, a oporba su im amebe i člankonišci.

Nice writing about teaching (TCS) and his personal experience (good and bad).

"Lunsford is a professor of writing and rhetoric at Stanford University, where she has organized a mammoth project called the Stanford Study of Writing to scrutinize college students' prose. From 2001 to 2006, she collected 14,672 student writing samples—everything from in-class assignments, formal essays, and journal entries to emails, blog posts, and chat sessions. Her conclusions are stirring."

"The truth is that most computer scientists will rarely need to use any piece of “useful” math. What they will constantly need to use is “mathematical maturity”: being comfortable with formal definitions and statements, being able to tell when a proof is correct, knowing when and how to apply a theorem, and so on."
