TY - JOUR AU - Temnikova, Maria PY - 2020/11/16 Y2 - 2024/03/28 TI - PRACTICAL PRODUCTIVE ACTIVITIES FOR THE DEVELOPMENT OF MATHEMATICAL COMPETENCES JF - Proceedings of CBU in Social Sciences JA - PSS VL - 1 IS - SE - DO - 10.12955/pss.v1.77 UR - https://ojs.cbuic.cz/index.php/pss/article/view/77 SP - 225-231 AB - <p>Development of knowledge, skills and competences for the mathematical quantity of “length” and its measurement units represent important part of the overall education in mathematics for students from Grades 1. – 4.&nbsp;</p><p>This research work systematizes some theoretical concepts related to the competences. Based on the analysis of the relevant legislation in force in the Republic of Bulgaria researchers presented the relations between the specific mathematical competences and terminology from the competency Cluster “Measurement”.</p><p>The research work is aimed at the development of such a methodology system of work which gives priority to practical productive activities thus facilitating development in primary school students of a higher level of knowledge, skills and competences related to the mathematical quantity of “length” and its measurement units.</p><p>The new system of work was applied during the compulsory classes in mathematics in Grades 1. – 4. The research work presents some of the developed and applied options of practical activity.</p><p>The researchers studied the objectiveness, the validity and the reliability of the set of tools and means used for doing diagnostics as well as the difficulty and the dividing (separating) strength of the mathematical tasks included in it. The results from the experimental work were statistically processed.&nbsp;</p> ER -
