Mrs. Jolie Geluk

Jolie Geluk is an alumni of Oakmont High School.  She went on to earn degrees from Sierra College, UC Davis and National University.  She was a student athlete in high school, and continued at Sierra College and UC Davis, mainly competing in track and field, but also playing basketball for two years at Sierra.  Prior to becoming a teacher she worked in the financial industry for E*Trade and Edward Jones Investments.  While she enjoyed the fast-paced world of finance, she found that she was drawn to teaching and working with youth.  She volunteered with Big Brothers/Big Sisters and Junior Achievement while working in the world of finance.  When the post 9/11 market struck, she made the decision to go back to her roots, and original career goals to become a teacher.

Jolie was a substitue teacher in the Roseville area while working on her teaching credential, and in the second year of the program she moved to London, England, where she continued to work on her credential through National University's online program.  The biggest value to her as a teacher was the opportunity to work as a full time teacher in London, in a diverse range of schools.  She worked at a variety of schools while in London, including Winchmore School, Grey Court School, The Godolphin and Latymer School and Tiffin Boy's School.  While in the UK Jolie taught Biology, Chemistry and Physics to students aged 11-18.  She also held the position of Assitant Curriculum Leader of Biology at Tiffin Boys School.  While in London, she became an active member of the rowing community, and competed for Vesta Rowing Club, as well as becoming a rowing coach for Tiffin Boys School.  Jolie spent 8 years in London.

While in Europe Jolie got married and had 4 children.  The whole family moved back to California in 2010 and she worked for one year at Sacramento High School in Oak Park.  When the job position for Oakmont High School was posted, she was excited for the opportunity to return to her Alma Mater and teach Biology.  In the fall of 2011 she returned to the home of the Vikings and joined the Oakmont Staff.

While at Oakmont she has taught CP Biology, IB Biology, served as Department Chair of Science, and on the district-wide CCAT team. In her current role as IB Coordinator Jolie is enjoying working with the whole school community to grow the program to be an inclusive, supportive, successful program and integral part of the Oakmont Campus and Community.

Jolie is also employed as an examiner for the International Baccalaureate program, and is very involved in the IB school world community, as well as a member of CAWS, the California Associate of World Schools.

In her spare time, Jolie can be found poolside, courtside or field-side as she is a busy mom with 4 active kids who are on swim teams, soccer teams and basketball teams.  She and her family enjoy traveling and spending time outside.

  • IB Biology    Mrs. Geluk

    Welcome to IB Biology at OHS! This will be a fast paced and exciting year that will expose you to many aspects of the science of Biology.  Before we can get started, you need to be aware of how this course is set up and will be run.  It will probably be quite different to other courses you may have taken in the past.


    While there no specific requirements, most students find the following items useful/necessary for class:

    • Lined Paper
    • Plain Paper
    • Multi-colored pens
    • Pencils
    • Ruler
    • Scientific Calculator
    • Binder with Dividers
    • Highlighters

    Class Organization

    There are 2 different pathways for IB Biology, Standard Level and Higher Level.  Each pathway consists of two courses:

    IB Biology SL-1 and  IB Biology SL-2  or  IB Biology HL-1 and IB Biology HL-2

    Students completing the SL course will take the SL exam in May of the year they complete IB Biology SL-2.  Some students may do SL Biology in one year, taking SL-1 in the fall and SL-2 in the spring.  Other students may spread it over two years, taking SL-1 in the junior year and SL-2 in the senior year.

    Students completing the HL course will take the HL exam in May of the year they complete IB Biology HL-2.  IB Biology HL-1 must be taken in the junior year and HL-2 in the senior year.  There are no exceptions to this as this is an IB Rule, not an OHS rule.

    The content covered is as follows for each pathway:

    SL Content (Core)

    • Cell Biology
    • Molecular Biology
    • Genetics
    • Ecology
    • Evolution and Biodiversity
    • Human Physiology

    HL Content (AHL)

    • Nucleic Acids
    • Metabolism, Cellular Respiration and Photosynthesis
    • Plant Biology
    • Genetics and Evolution
    • Animal Physiology

    In addition, both SL and HL will study ONE of the following options in more detail:

    • Neurology and Behaviour
    • Biotechnology and bioinformatics
    • Ecology and Conservation
    • Human Physiology


    The assessment model for the course will mirror the assessment model for IB, and serves to prepare students for success on the end of course exams that are administered by IB.  The weighting and details of the end of course exams administered by IB are as follows:

    The IA (Internal Assessment)

    The IA is a full lab write up that students will complete towards the end of the course.  More information about the IA will be provided later in the term.  The IA is a required component of the IB course, and students who fail to complete the IA will not be able to register for the exam.  If students fail to turn in the IA after they have already registered and paid for the exam, no refund is available for the exam fee.

    Grading of the IA will follow the IA Rubric provided by IB, which is available in Managebac.  There are 7 required labs that must be completed as part of the course:

    1. Use of a light microscope to investigate the structure and ultrastructure of cells and tissues, with drawing of cells and calculation of the magnification of drawings and the actual size of structures shown in drawings or micrographs.
    2. Estimation of osmolarity in tissues by bathing in hypotonic and hypertonic solutions
    3. Experimental investigation of a factor affecting enzyme activity.
    4. Separation of photosynthetic pigments by chromatography
    5. Setting up sealed mesocosms to try to establish sustainability
    6. Monitoring of ventilation in humans at rest and after mild and vigorous exercise
    7. Measurement of transpiration rates using photometers (HL only)

    Each of these labs serves to prepare students for success either on their individual IA, or to build skills for success in future lab work.  The IA is graded along 5 criteria:

    1. Exploration
    2. Analysis
    3. Evaluation
    4. Personal Engagement
    5. Communication

    Each required lab is arranged to prepare students for one of the criteria or skills listed above:


    Skill or Criteria

     1.   Microscopes

     Skills to be used in further studies of cell biology

     2.   Osmolarity lab


     3.   Enzyme lab

     Analysis and Evaluation

     4.   Chromatography


     5.   Mesocosms

     Exploration, Analysis and Evaluation

     6.   Ventilation

     Exploration, Analysis and Evaluation

     7.   Transpriation

     Analysis and Evaluation

    Each of these 7 labs will require a full write-up.  Each lab is worth 100 points, 70 of which come from turning the lab in on time and in the appropriate format (Communication and Personal Engagement Crieteria)).  The remaining 30 points are derived from the student’s score based on the IB rubric for internal assessments (available on Managebac).  For each day the lab is late 10 points will be deducted from the score.  All due dates and times are listed in Managebac, and students are required to upload their work to Managebac BEFORE the time indicated.  Any work submitted late will incur the 10 point penalty.

    Tests and Quizzes

    Quizzes will happen frequently and serve to give quick feedback to students about their understanding of the material.  The class embraces the concept of formative assessment for learning.  Not all quizzes will go into the gradebook.  Any that do are available for retakes up to the day before the exam.  Retakes must be taken during intervention and is up to the student to request.  All quizzes are out of 10 points and a score of 8/10 or above is considered passing.

    Each topic will have an end of topic test that follows the assessment style of the IB Exams students will take in May of their Senior year.  These exams are used extensively to help prepare students in the IB Assessment model and are all graded according to the IB rubric.  As the IB Grading Scale operates on a scale of 1-7, and our Oakmont grading operates on an A-F scale, adjustments to the raw IB Score are made in order to convert IB Scores to Oakmont Scores.

    Oakmont Grading

    The overall weighting of the course in the Homelink gradebook is as follows:


    Percent of Grade



    IA and Labs




    Exams (End of topic exams, Midterm and Final)



    Many of our assignments, and all resources for the class will be posted to Managebac.  This is an online system that students will need to be checking and working in daily.  It is used for most IB classes on campus.  If Internet Access at home is a problem, please bring that to the attention of the teacher as soon as possible.  You should have received a welcome email to access Managebac, if you did not, please let Mrs. Geluk know as soon as possible.
