AGENDA AT THE SCHOOL

When organizing education at Erudito Licėjus, it is important to allow pupils to experience and perceive the connections between their efforts and outcome. The teacher needs to focus on the process that reveals the relationship between goal- effort-outcome. Different class groups work on slightly different agendas at Erudito Licėjus. Lessons are organized this way for several reasons:

• School opening hours: Monday – Thursday 8 a.m. – 6 p.m; Fridays 8 a.m. – 5 p.m.
• Most lessons are organized in the form of blocks (double lessons). Therefore, we take breaks between blocks but not in the middle of them.
• Lessons are organized in a block format at Erudito Licėjus. The duration of the blocks is 75 minutes for grades 0–1, and 90 minutes for grades 2–12.
• Thanks to such a longer lesson duration, teachers have more time to organize more diverse and inclusive educational activities and to apply active educational methods.
• In the middle of the lesson, pupils take a short agile break, or agile and active methods are combined throughout the duration of the block.
• Primary school classes have 3 blocks per day, grades 5–7 have 3.5 blocks daily, and grades 8–10 have days in the middle of the week when they have 4 blocks.
• Since different grades at our school are attended by children from the same families (siblings), we want to organize the lessons so that they end at nearly the same time for most grades, with as few pupils as possible from different grades gathering in the canteen during breakfast and lunch. After staggering the lunch times of different grades, we managed to prevent crowding in the corridors during that time.
• With the school working to different schedules, using a school bell becomes impractical. Lessons at Erudito Licėjus begin and end when the teacher announces.
• The primary school teachers prepare a schedule for primary classes and place it in ManageBac.
• Of The timetable for the lower-secondary classes and gymnasium grades is prepared for six months at a time.
• All contextual and outgoing lessons outside Vilnius or Kaunas are organized for an additional fee, which the homeroom teacher coordinates with the parents. Once approved with the families, the school organizes a planned contextual outgoing lesson. The school allocates the budget for contextual / educational lessons outside the school in Vilnius and Kaunas cities.

TIMETABLE

• Homeroom teachers will share primary school timetables in a closed-class Facebook group.
• Secondary school timetables will be shared by e-mail or other communication means used by homeroom teachers.

As the winter season approaches and daylight hours shorten, we want to draw your attention to the safe commute to and from school and highlight a few key points:

1. Proper attire. Please ensure that your children are dressed appropriately in the morning and evening. Dark clothing does not reflect light well, so we recommend choosing bright or light-colored clothing.
2. Reflective elements. Reflective belts and other accessories can improve children’s visibility. We encourage their use when going to and returning from school.
3. We would like to remind you that there are two pedestrian crossings, approximately 100 meters to the left and right of the school. If you cannot drop off your children near the crossings, please disembark them on the same side as the school.
4. Please discuss and remind your children of safe traffic rules (e.g., not running across the street, looking in all directions) to ensure they can safely arrive at school without jeopardizing their health.

We seek the highest standards in the learning process and believe that this should be reflected in the behavior and appearance of lyceum students.

Self-reliance – we strongly believe that the intellectual growth of each child begins from the ability to independently search for solutions, to have a responsible opinion of their own and the ability to listen to the opinions of others and seek a consensus.

Friendliness – children need to understand and feel early on that they will always achieve more in life by acting in cooperation with others, that everyone’s contribution will be strengthened if friendly, respectful and ethical cooperative relationships are fostered.

Citizenship – commitment and concern for others is the key to success. If children learn from the outset to treat others as they would like to be treated themselves, a responsible attitude will be formed by the consequences of their actions – the basis of citizenship.
