In this paper, we study the staircase encoding of permutations, which maps a permutation to a staircase grid with cellsfilled with permutations. We consider many cases, where restricted to a permutation class, the staircase encoding be-comes a bijection ...

When modelling side-effects using a monad, we need to equip the monad with effectful operations. This can be done by noting that each algebra of the monad carries interpretations of the desired operations. We consider the analogous situation for graded ...

Landspróf miðskóla sem inntökupróf í menntaskóla og kennaraskóla og síðar fleiri skóla var haldið á árunum 1946–1976. Prófað var í átta námsgreinum þar sem íslenska vó tvöfalt. Landsprófið var upphaflega grundvallað á reglugerð nr. 3/1937 um námsefni ...

Athugun á niðurstöðum í stærðfræði í PISA-rannsókninni 2003 sýndi að árangur nemenda í tveimur stærstu skólunum var marktækt betri en í minni skólum. Sérstaklega var árangurinn slakur í skólum með 11–25 þátttakendur. Athugun á árangri í dönskum skólum ...

The New Math was implemented in Iceland with the intention to facilitate understanding in the midst of increased demands for education for all. The article contains an analysis and comparison of typical papers in a selective entrance examination into ...

The first main theme of this thesis is the approximation of holomorphic functions on Stein manifolds by polynomials. In our setting a polynomial is an entire function whose absolute value is bounded from above by $\exp(a\psi+b)$ on the complement of a ...

The paper describes two Icelandic arithmetic textbooks, published respectively in 1780 and 1911–14, both written at the beginning of an era when enhancing general education was placed on the agenda for restoring the Icelandic society after natural ...
