Comment: The student explained the concept of the matryoshka doll in the introduction of the investigation which ensured that they outlined the topic clearly as it's the only concept included which should be explained. The student also indicated the topic of the exploration, i.e. " I decided to choose the largest and smallest matryoshka in the set, find their surface area and volume using integration, and then see if they both share a common scale factor"

Comment: The student stated their interest in calculus and that they would explore the topics connected to the calculus section in the exploration such as the integration or volume calculations

Comment: The student provided a summary table in the last section of the main text of the exploration which included a summary of the height, total surface area, and volume of revolution of the matryoshkas analyzed. The steps of the exploration are briefly described in the last section along with the response to the aim, i.e. "his would suggest with change of size between two corresponding dolls the ratio of height, total surface area and volume of revolutions would stay the same. Thus, it can be deduced that either one of the matryoshkas is an identical representation of the latter, just of a different size"

Comment: The student indicates the use of GeoGebra throughout the investigation in multiple places of the work

Comment: The student provided a description of the use of Geogebra software and included the link to the software in the "Bibliography" of the exploration, however, there was no description of the purpose of the software present in the work. The student should have included a description of the higher accuracy of the software, for example as a justification for the use of the software

Comment: The student used correct terminology throughout the whole work. The notation was also applied correctly with equations present in a mathematical form instead of being included as a main text which might be present in some works, however since the highlighted part is an approximation, they should include a sign of "≈"

Comment: The student explained the variables which were present in the work such as the quadratic formula, matrices, etc. This ensured that the key terms applied in the investigation were introduced to the reader before the use of them in the calculations was done

Comment: The student provided no descriptions of the possible concepts that were present in the main text. The student should have included descriptions of the modeling, volume, and surface area as well as matrices that were used in the work. In such a way the student would outline the main concepts of the work and therefore would describe the context of the analysis of the matryoshkas

Comment: Throughout the work, the equations were not presented with a description of the variables present in them. The student should have provided an indication of what each of the variables meant when each of them was introduced to ensure that the additional terms that were used for calculations were introduced well

Comment: The student described the calculation process presented in the exploration and provided sufficient explanations of the data presentation included

Comment: Although it was not a detrimental mistake, the tables are labeled at the top instead of the bottom. The student should have included the labeling at the bottom
