Luet oppimateriaalin englanninkielistä versiota. Mainitsit kuitenkin taustakyselyssä
osaavasi suomea. Siksi suosittelemme, että käytät suomenkielistä versiota, joka on
testatumpi ja hieman laajempi ja muutenkin mukava.
Suomenkielinen materiaali kyllä esittelee englanninkielisetkin termit.
Kieli vaihtuu A+:n sivujen yläreunan painikkeesta. Tai tästä: Vaihda suomeksi.
Addition to this page on Oct 27th, 2021
In addition to the Zoom labs, we will have a small number of weekly
lab sessions on site in Otaniemi in November and December. The teaching
assistants will be there to help you in person.
We’ll initially have these in-person labs on Wednesdays between 16–18
and on Thursdays, also at 16–18. We might later add or reduce the number
of these labs once it is clearer how many students are interested in
These sessions will be in the Linux classroom Maari-A in the Maarintalo
building (Sähkömiehentie 3, Espoo).
The first session is on Wednesday, November 3rd. There’s no need (or
way) to sign up through Sisu or MyCourses, or otherwise; just show up.
However, please do note that, for the time being, you’ll need an
access card to enter the building; it’s easy to get that, as described
The online sessions on Zoom will continue as before.
There are several lab sessions every day except on weekends, from the afternoon of September 15th,
2021, onwards. This is where you can come to discuss programming with the course staff and get help on
the assignments. Due to the pandemic, the Fall 2021 “lab sessions” will be implemented at distance
using Zoom. For the exact schedule and instructions on how to join, see below on this page.
Aalto students only, sorry!
Because of the exceptional circumstances this year, the “lab
sessions” described on this page are only open to students with
an Aalto user account. If the situation permits, we may choose
to open some of the sessions to other students as well, in which
case we’ll announce that separately. The Piazza forum serves all
students including those external to Aalto.
The sessions start a quarter past the indicated hour, but you can come and go as you please.
There’s no set agenda: you can ask for help as the need arises, and the teaching assistants
will advise you individually.
Participation is voluntary but highly recommended. You don’t need to — and can’t —
sign up in advance.
The assistants can help you in English, Finnish, and (at some sessions) Swedish.
In Fall 2021, the “lab sessions” will take the form of Zoom
video calls where students can discuss their program individually with a teaching assistant.
We’ll use A+’s Lab Queue feature to allocate turns to each student (or pair of students).
If you are unfamiliar with Zoom, please try it out well in advance before joining one of
Install Zoom on your computer as per Aalto’s Zoom Quick Guide.
Zoom may be initially configured to mute any teaching assistants that enter your
Zoom meetings. Please ensure that this is not the case:
Test your video and audio in advance to make sure they’re working in Zoom.
Zoom in the browser
Instead of a separate Zoom app, you can use Zoom in your web
browser. If you do, here’s how to launch it:
If you use Zoom in the browser, you’ll also need to adjust your
browser settings to let Zoom access your microphone and camera.
You don’t have to (and can’t) sign up in advance. When you want to talk to a teaching
assistant, do the following.
Before you join the queue, start a Zoom meeting:
With the Zoom meeting running, enter the Lab Queue:
Especially when the queue is long, the assistant cannot spend very long in one meeting.
For that reason, too, please be prepared when it’s your turn!
In order to help you, the assistant will typically need to see the program that you’re
working on. You can share your computer’s screen with the assistant by selecting, at
Zoom’s bottom edge, Share → Screen and confirming with Share.
In Zoom’s bottom-left corner, there’s a little microphone symbol. Check to see that your
microphone isn’t muted; or if it is, click the symbol or press Alt + A. If you
can’t hear the assistant, make sure they aren’t muted by checking Participants
at Zoom’s bottom edge. When you mouse over the assistant’s name in that list, you’ll
see a Mute/Unmute button. While resolving audio trouble, you can resort to Zoom’s
textual Chat, too.

Thousands of students have given feedback that has contributed to this ebook’s design.
The ebook’s chapters, programming assignments, and weekly bulletins have been written in
Finnish and translated into English by Juha Sorva.
The appendices (glossary, Scala reference,
FAQ, etc.) are by Juha Sorva unless otherwise specified on the page.
The automatic assessment of the assignments has been developed by: (in alphabetical order)
Riku Autio, Nikolas Drosdek, Joonatan Honkamaa, Jaakko Kantojärvi, Niklas Kröger, Teemu
Lehtinen, Strasdosky Otewa, Timi Seppälä, Teemu Sirkiä, and Aleksi Vartiainen.
The illustrations at the top of each chapter, and the similar drawings elsewhere in the
ebook, are the work of Christina Lassheikki.
The animations that detail the execution Scala programs have been designed by Juha
Sorva and Teemu Sirkiä. Teemu Sirkiä and Riku Autio did the technical implementation,
relying on Teemu’s Jsvee and Kelmu toolkits.
The other diagrams and interactive presentations in the ebook are by Juha Sorva.
The O1Library software
has been developed by Aleksi Lukkarinen and Juha Sorva. Several of its key components
are built upon Aleksi’s SMCL
The pedagogy of using O1Library for simple graphical programming (such as Pic) is
inspired by the textbooks How to Design Programs by Flatt, Felleisen, Findler, and
Krishnamurthi and Picturing Programs by Stephen Bloch.
The course platform A+ was originally created at Aalto’s LeTech
research group as a student project. The open-source project
is now shepherded by the Computer Science department’s edu-tech team and hosted by the department’s IT
Markku Riekkinen is the current lead developer; dozens of Aalto students and others have also contributed.
The A+ Courses plugin,
which supports A+ and O1 in IntelliJ IDEA, is another open-source project. It was created by Nikolai
Denissov, Olli Kiljunen, Nikolas Drosdek, Styliani Tsovou, Jaakko Närhi, and
Paweł Stróżański with input from Juha Sorva, Otto Seppälä, Arto Hellas, and others.
For O1’s current teaching staff, please see Chapter 1.1.
Niklas Kröger wrote the instructions for Zoom labs, drawing on similar guides by Mikko
Kivelä and Kerttu Pollari-Malmi; Juha Sorva translated the instructions to English.
