20 master's and 17 bachelor's theses have been defended under my supervision since 2007. In addition, I have been a supervisor for 16 research papers in the Core Study. Currently I am supervising one doctoral student; the topic of her thesis is "Economic Growth and Financial System Development in Consolidating and Globalizing Environment".
I have met many business people who have told me that they would never use statistics because they consider statistics as complicated calculations. In my opinion teaching statistics should motivate people to use statistics in their work and everyday life without any terrifying complexity.
Learning statistics is impossible without practical data analysis. However, until this year there was no statistics textbook with downloadable data files written and published in Estonian. Nowadays it is not a readerfriendly approach to publish printed data tables so that one must independently enter the data to calculate examples and to solve data analysis problems. This was the main reason to publish my statistics textbook (Sauga, A., Statistika õpik majanduseriala üliõpilastele, 2017, TTÜ Kirjastus, 766 lk). The textbook was published under the programme of the Estonian language textbooks for higher education institutions, funded by the Ministry of Education and Research. The programme supports publishing Estonian study and research literature and the main goal is to develop the scientific terminology of the Estonian language.
The textbook introduces basic statistical methods and their application in solving various business and economic problems. Guidance for the statistical data analysis in Excel and LibreOffice Calc is provided. There are nearly 200 examples in the textbook, most of which can be found in the spreadsheet files attached to the textbook. Example files include calculations and explanatory comments. There are over 400 exercises to be solved independently, about half of which need to be solved in the spreadsheet, using the data from the attached files. All exercises are equipped with answers. The vast majority of the data used in examples and exercises comes from the real life. The sources of data include online databases, scientific publications, published surveys, supervised student works, etc.
I have been using the possibilities of Internet to support my courses since the end of the 90's. At first I made all teaching and learning materials (lecture notes, spreadsheet files) downloadable from my homepage. Later I included some screen videos, made with software Wink. As the feedback about performance and selfassessment are important in the learning process, I learned HTML language and Javascript to design and build quizzes including multiplechoice and truefalse questions.
Nowadays there are many elearning environments, which carry out this kind of tasks. In TUT we use an opensource learning platform Moodle. All my lecture courses are supported by the corresponding ecourse in Moodle. There are lecture slides, data files, selftests, forums and links. For example, the question bank of the Statistics course contains 230 questions in various formats, grouped by the topic. These questions are used to build selfassessment quizzes to help students quickly see what they know and do not know. Wrong answers are provided with comments. There is a quiz after each lecture and students should complete it before the next lecture. This motivates students to study consistently during the semester.
Since my first lectures in statistics I have implemented many different approaches to visualize my teaching. I have used Visual Basic in MS Excel to create interactive plots and calculations, but the possibilities of Excel are somewhat limited and therefore I have also used more advanced approaches. For the past six years, I have used Computable Document Format (CDF) to design different interactive demonstrations. CDF is launched by Wolfram Mathematica (http://www.wolfram.com/cdf/) and it is powerful technology to build presentations that are dynamic and interactive. You can change the parameters, rerun models and present results. Using computer simulations, one can take thousands of samples to illustrate, for example, type I and type II errors in hypothesis testing or biased and unbiased estimators. To view CDF document, one must install Wolfram CDF Player, which is free. All CDF demos (44 in Statistics and 11 in Econometrics) are available on my homepage http://www.sauga.pri.ee/cdf/ (in Estonian, some of them are translated into English). So, students can independently work with these demos to understand the statistics and econometrics concepts. It is a great feeling to experience that a welldone visualization has made the material much clearer and more interesting for students.Statistics and Econometrics courses both have computer labs in the schedule, but it is important that students have a possibility to deal with practical data analysis independently. Thus, they should have the opportunity to use the suitable software.
In Statistics course we use MS Excel in the computer lab. All TUT students have free access to download and install MS Office in their own computer and thus they can use Excel outside the computer lab too. Their second option is to use freeware LibreOffice. Instructions for the statistical data analysis in Excel and LibreOffice Calc are presented in my textbook.
In Econometrics course for masters students we use econometrics software Gretl (http://gretl.sourceforge.net/). It is free, opensource software and students can download and install it in their own computer. Its main features are: easy intuitive interface, a wide variety of estimators, time series methods, models with limited dependent variables and paneldata estimators. To support students I have written the online user guide for Gretl in Estonian (http://www.sauga.pri.ee/gretl/).
In doctoral courses we use econometrics software Stata and EViews.
The test paper accounts for 20%, student's activity 10% and exam 70% of the final grade.
In the Econometrics course I use the following assessment methods:After completing the test paper and the exam all students receive an individual feedback in Moodle.
The test paper accounts for 20%, home assignment 25% and exam 55% of the final grade.
Teaching is very important for me and I put a lot of time, energy and emotion in it. I am greatly interested in how effective my efforts have been and therefore I observe the students' feedback every semester, which I find very useful. The average score for the Statistics course (Spring 2016) was 4.58 and the average of Econometrics course (Fall 2016) was 4.9 according to the students' feedback.

From 2011 to 2013 I participated in the project which goal was to create teaching and learning materials for the high school mathematics course "Foundations of Mathematical Economics" (project number K103). Our team prepared the materials for 35 academic hours: a textbook, slides and methodical material for teachers, ecourse in Moodle.
In 2013 our team won the public procurement to create teaching and learning materials for the other high school mathematics course "Mathematical applications, study of real processes". We prepared the materials for 35 academic hours: textbook, computer based tasks, interactive demonstrations in CDF format, slides and methodical material for teachers and ecourse in Moodle.
In summer 2013, I was invited to give a presentation on the Math Teachers' Days. I presented two new sets of learning materials, which were prepared by our team.
In 2011, I was proposed to write some articles for the journal "Raamatupidamise Praktik" ("Accounting Practitioner"). As a result, six articles about the statistical averages, percentage calculation, logarithms, index numbers, present and future value of money and annuity were published.
In April 2007, I received an invitation to lead a workshop in economic analysis for the employees of the Statistics Estonia.
In Nov, 2006 we performed two radio broadcasts with journalist and editor Priit Ennet on the topic "Can noise be useful?".
