Incorrect

Criterion A: The work is divided into sections: introduction, body, and conclusion.

Comment: The work should be divided into three main sections: introduction, exploration, and conclusion. Those sections should then be further subdivided

Correct

Criterion A: The topic of the Internal assessment is stated clearly and explained in the introduction

Comment: The student clearly states the topic of their work in the title - 'Analytically evaluating and generalizing an integral from the Putnam mathematical competition'. It is then further explained in the introduction

Correct

Criterion A: The introduction includes a general description of the student's approach to the topic and what area of the math curriculum the exploration focuses on

Comment: The student clearly states the aim of the exploration and how they plan to approach the problem, as shown in the highlighted parts

Correct

Comment: The student clearly states the aim of the exploration and how they plan to approach the problem, as shown in the highlighted parts

Correct

Criterion A: The conclusion is a summary of the outcomes and a response to the aim of the exploration stated in the introduction

Comment: The conclusion responds to the aim and summarizes the findings of the investigation

Incorrect

Criterion A: The use of technology, when applied, is clearly indicated and explained

Comment: The graph seems to be made using technology, which is not indicated in any way. The student should explain how they obtained the graph

Incorrect

Criterion A: The graphs, tables, and diagrams are present in appropriate places (in the body paragraphs, after their descriptive introduction)

Comment: The introduction for the graph is on the previous page. It would be better if the graph was right under the description of what it presents

Correct

Criterion B: Key terms/variables are defined and explained when first introduced

Comment: All terms and methods are clearly explained before used. The highlight shows a good example of an explanation of integration by parts


Correct

Criterion B: The main concepts are described in the introduction

Comment: The students explains mathematical concepts before they use them

Correct

Correct

Criterion B: Key terms/variables are defined and explained when first introduced

Comment: All terms and methods are clearly explained before used. The highlight shows a good example of an explanation of integration by parts

Correct

Criterion B: Additional terms are defined in detail in appropriate places (dependent on the development of the exploration)

Comment: The student explains all necessary terms before use and with new development, they introduce new terms and methods accordingly. For example, in the highlight, since integration by parts did not yield a solution, the student introduced substitution

Correct

Criterion B: All mathematical calculations are explained and any data presentation is described

Comment: The student explains each calculation well and does not take any shortcuts, to ensure the reader has a clear understanding of the development of the exploration

Correct

Criterion B: The student used a deductive method and set out logical proofs where appropriate

Comment: The student uses logical thinking to reflect on the current state of the investigation and what should be done for its development. An example is shown in the highlight
