IB Applications and Interpretations HL is a rigorous two-year integrated college-level course for prospective STEM major students, with emphasis on modeling, applied linear algebra, and statistics. This course is specifically recommended for STEM majors with a heavy focus on applied math skills: computer engineering, organic chemistry, applied physics, or any other engineering majors in the science field. Applications and Interpretations focuses more on applied mathematics. In HL, students are introduced to various topics in advanced statistics and probability, graph theory, applied linear algebra, and differential equations.

Unlike the standard US subject-specific curriculum, IBH Applications covers various topics in mathematics, such as Quadratics, Functions, Exponentials, Logarithms, Affine Transformations, Complex Numbers and Polynomials, Sequences and Series, Permutations and Combinatorics, Trigonometry, Vectors, Linear Algebra, Graph Theory, Differential and Integral Calculus, Advanced Calculus, Statistics and Probability, in a course of two years. At the end of the two-year course, students are expected to take the IBH Applications exam.

Students are also required to complete an Internal Assessment, which is a mathematical exploration. This is a report based on a topic of the student’s choice, focusing on the mathematics of that topic. The internal assessment comprises 20% of the final external IB marks. The exploration is approximately 6-12 pages long, and written at a level accessible to an audience of the student's peers. It is expected that this internal assessment will require a total of 10 hours of work. We will discuss possible topics in the first year. Students should decide on the final topic over the Summer of the first year, and the writing of the assessment will take place in the first half of the second year.

Every written assignment (HW and tests) must be done with a black or blue pen since every IB Math paper only permits writing with a black or blue pen. However, you may use a pencil for sketching a graph or graphing.

• Grades 11 & 12

• Most recommended for students coming from AP Calculus AB (with a score 4 or 5) or good Pre-Calculus grades in 10th grade

• Teacher Recommendation

• HIGHLY recommended, ONLY IF POSSIBLE (consult with Ms. Lee), to take AP Calculus AB concurrently in junior year, if coming from Pre-Calculus (Not necessary)

• 5% Participation

• 30% Homework

• 25% Journals / IA

• 40% Tests

Participation

• Students are expected to be on time for every class, and be ready for the day's activities when class begins. Students are expected to come to class prepared with all required supplies each day. 

• Each day, students can earn a participation grade on a scale from 0-5 according to: being on time (1), coming prepared (1), engaging in class and staying on task (2), and demonstrating a positive respectful attitude (1).

Homework

• Every homework given on a daily basis will be graded for completion on a scale from 0-5. All homework must be submitted in the submission box before the class starts. Completion is graded on effort, not accuracy, and is not necessarily a reflection of the type of grade a student should expect on assessments. 

• In order to receive full credit on completion, students must show all work and attempt all problems. Even though a student is not able to solve all problems, one must try the best, and keep all the work process for future review and feedback. This is one of the most important attitudes in mathematics. 

Journals / IA

• Throughout the two years, students will write math journals on a shared Google Drive. The journal assignments will be done cooperatively with the IB AA HL class, so that both AI and AA students will gain broader perspectives and knowledge in each other's math. Each journal assignment consists of one main post and two comments. 

• Each main post is graded out of 20 points: 10 points on completion, and 10 points on the quality. Merely paraphrasing the materials, or inserting screenshots/captures of mathematical expressions from the textbook or external source, is not a good quality journal. A good quality journal consists of creative research topics and thoughts, personal engagement, and reflection. 

• Two comments are graded out of 10 points total: 5 points for each comment. Just as in the main post, each comment will be graded on completion and quality. One may write more than two comments, but the maximum points earned will always be 10 points. If a student writes more than two comments, the two comments with the best quality will be accounted for in the grade. 

• Starting the second year, students will work on Internal Assessments, and any related assignments will go under this category. 

Tests

• Tests will be given after each chapter, or two/three depending on the contents and the pace. They will be announced in advance.

• The emphasis on evaluation will be on the methods and procedures taught in that unit, and NOT on the correct answer. A student with an incorrect answer may earn more credit than a student with a correct answer depending on the work shown and justification given. IB and AP standards from math state: "Correct answers with no work shown will receive no credit."

• At the end of each semester, there will be a cumulative semester exam. The Year 1 Semester 1 exam will assess all of the materials covered in the first semester. The Year 1 Semester 2 exam will assess all of the materials covered in the whole year. The Year 2 Semester 1 exam will assess all of the materials covered in the whole year 1 and semester 1 of year 2. Since one of the primary purposes of this class is to be prepared for IB exams at the end of the senior year, the semester exams will consist of problems similar to the actual IB exam problems. Year 2 Semester 2 exam will be replaced with a group video project.

Mock and Practice Exams until the IB Exam in May

• 50% maximum (2.5 points) can be earned for late submission within 24 hours. No late submission will be accepted after then. 

• If a student is absent with an excuse, he/she has as many days to make up work missed due to absences as the number of excused days of absence that occurred. Excused absence requires an email from the school office or the student's parents/guardians, or the Transit Form entry. 

• IB Math HL courses run at a very rapid pace. For the most of the time, there is no or almost no time in class to discuss the homework or test questions. Therefore, it is extremely important that the students communicate with Ms. Lee, whenever there are questions. It is the student's responsibility to reach out when they need help.

• We will have a class Whatsapp group. Oftentimes, when you have a question on a problem, your classmates might have the same question as well. Or, sometimes your classmate can have a solution to your questions. So, we want to use the group chat effectively, for discussing questions amongst peers. Ms. Lee will be there to guide if you need a hint. 

• "I can proudly assure, that I am probably the fastest responder of any teacher at SJS! I will answer your questions any time, any day, even if it's 3 AM on Sunday, as long as I am awake. So please, PLEASE use me as much as possible! I am the best, free resource that you have!"
