About roumianaanguelova

I am a mathematics and informatics teacher in the Vocational School of Economics and Management, Pazardzhik, Bulgaria and also mathematician in the Institute of Mathematics and Informatics in the Bulgarian Academy of Sciences. I am also the Head of the Club for Extracurricular work "One and a half Percent". I am a STEAM Teacher! I work as Mascil multiplier at different levels: in my school, in my city and region, and аt national level. I have participated in several workshops on project Mascil, which gave me the opportunity to learn, to share ideas, approaches, experiences - to transform professional situations and real-life data in mathematical models. Within the MaSciL Project I developed the lesson "Maths Sweet" http://www.math.bas.bg/omi/mascil/task-mathsweets-bg.html I participated in: National Education Seminar, IMI-BAS, Sofia, 04.12.2015 with poster " Etudes with the Pick's Formula"; Annual Educational Conference, Sofia, 13-14.11.2015; Participation with Prize Excellent diploma of the conference "Dynamic Mathematics' with the performance" Mathematical dreams ", IMI-BAS, Sofia, 14.02.2015; National Scientix Conference, Sofia, 09.12.2014 with poster "Binary lessons as a pedagogical tehnologie"; National Education Seminar, IMI-BAS, Sofia, 08.12.2014 with article " The dialogues between Mathematics and Art"; National Education Seminar, IMI-BAS, Sofia, 17.12.2013 with article " The arbeloses "; National Education Seminar, IMI-BAS, Sofia, 19.12.2012 with article "From the wheel to the Kalofer lace"; International Scientific and Practical Conference KeyTTT, Stara Zagora, 22-24.09.2011 Pestalozzi Programme, Workshop DEMOCRACY IN BASIC EDUCATION, CoE 2013 1001-1004 FINLAND, 01 - 04.10.2013 Pestalozzi Programme, Workshop HOW TO DEVELOP INCLUSIVE SCHOOL CULTURE FOR SUPPORTING COOPERATION AND PARTICIPATION COMPETENCIES , CoE 2016 1024-1028 ESTONIA, 24 - 28.10.2016 I participated at HST 2015 CERN's program. Since 2013 I work on the project Scientix, and as a trainer of teachers I present the project, its activities and opportunities. I participated in the Second Scientix conference, Brussels, 2014, Workshop (SPW@FCL11) in the FCL, 18.03.2016. For me this participation is a significant inspiration for active work with my students! I fully completed Our Wonderful Universe Course, Progressing Technology-Enhanced Teaching (MENTEP), Mentoring in Schools, Opening Schools to STEM Careers, Our fragile Planet and Opening Minds to Stem Careers in MOOC. I participated in Summer School on Next-Lab Project, Marathon, Greece, 09.07-14.07.2017. I am fully committed to the idea of disseminating STEAM Learning within the project Scientix and Next-Lab! I am Scientix Ambassador for Bulgaria.

Mathematics and Ecology

Author: Roumiana Anguelova

Two classes 10A and 10B from February 2020 worked on the topic “Mathematics and Ecology”. The students were divided into small study groups ( 3, 4 or 5 students):

  • Fuel Analyzers;
  • Heating Analyzers;
  • Water Pollution Analyzers;
  • Аir Pollution Analyzers;
  • Soil Contamination Analyzers;
  • Acid Rain Analyzers;
  • Specialist car catalysts;
  • Chemists;
  • Pulmonary Disease Experts.

The mathematics teacher set up tasks that had to be solved with graphs, mathematical models, working with nano-dimensional units. The chemistry teacher led the teams. The online event was held as a binary lesson on 29th of April in Microsoft Teams Office 365.

Each group of analysts was working on a problem related to the causes of disturbance of ecological balance and its consequences. Each team developed a presentation or movie, outlining the measures. The groups are currently continuing their work online.

How does the Moon move?

The project’s preparation was held in the form of small study – research groups (3-5 students), it was continued from December 2018 to April 2019. Every month the groups received tasks on which they worked and prepared their scientific messages, presentations and models. 52 students from Vocational school of Economics and Management, Pazardzhik, Bulgaria and several students from different schools with whom the Vagabond Foundation took part in this project. The project manager is Roumiana Anguelova with assistant teachers Angel Angelov and Sasho Yordanov.


The final part was the event, which took place on April 24 at 12.30 am as a binary lesson – within 2 hours, led by 2 teachers. 11 presentations, 4 models, 8 boards and posters were presented at the STEM event. In addition to the 60 participating students, each of whom worked on a research assignment and introduced himself with his small study group, about 100 students attended and watched the lesson. The project is a sequel of Mars Mission, with which we participated in STEM Discovery Week 2018.

In the research, the headmaster directed the students to get acquainted with specialized literature from the journal Kvant and NASA’s publications. We also used resources from Scientix repository Resource :



Different aspects related to the Moon and people in the past and now have been presented. The phases of the Moon, mathematical aspects related to Moon movement, were explored.

Two of the groups offered interesting business ideas to use moon movement and tides to get electricity and water purification.

Moon motion pictures are also produced:


We are a partner of STEM Discovery Week 2019.

Fair of natural sciences at the Vocational School of Economics and Management, 25 April 2018


As part of the STEM Discovery Week 2018, more than 120 students and 10 teachers organised and held a Fair of natural sciences at the Vocational School of Economics and Management, Pazardzik, Bulgaria.

About 50 students participated in the project Mars Mission. The students explored, compared the characteristics of planet Earth and Mars. They created a code and programmed messages to Mars. We had arranged chairs of chemistry, physics, biology, and robotics in the courtyard of the school. There the students who made experiments and discoveries, assembled robots of cosmic crickets. Also we organised a mathematical domino tournament with Tonediko.
