Test reflection...

Reflect on the exam:
Look through the objectives from the Unit sheet. Rank yourself 0 to 4 on the unit sheet in the "end of unit" column.

1. Which objective do you think you did the best on? Why?

I believe that vocabulary was one of my strongest objectives for this test. Last test I struggled with the vocabulary. So before taking this test I made an effort to review the vocabulary terms and ensure that I could easily define each word, use it in a sentence, and apply them to problems.
2. Which objective do you think you need the most improvement on? Why?

I had a real hard time with solving systems on the test. I think I did not review how to do systems because I have been fairly good at them in the past. However, after not practicing solving systems for a long time I seemed to forget everything I knew as soon as I got my test.
3. What can you do to improve on the objective you may still need help on?

I can use the book to review how to do them. I can also do practice problems, or come in for help until I am able to do them well.

CV Formative Assessment

1. Total distance: 6 meters
2. Displacement: + 2 meters
3. No, the displacement is less than the total distance because the ball rolled all the way to the wall- then bounced back. The distance measures the number of meters to the wall & back to the place where the ball finally stopped. Whereas, the displacement measures just the number of meters from the origin to the end point.

Tumble Buggy Lab (Data & Graph)

Time (seconds)	Trial #1	Trail #2	Trail #3	Trail #4	Trail#5	Average	Uncertainty
2	59	59	60	60	61	60	+/- 0.95
4	123	117	116	119	120	119	+/- 3
6	184	179	180	178	180	180	+/- 1.5
8	284	281	280	281	283	281	+/- 1.5
10	393	390	392	390	391	391	+/- 1.5

Graph: 

Mathematical Relationship: 

                            Time= 41.3 (cm/second) * Distance -41.2 

                                                                                              ^ In theory, this number should be zero

Explanation of uncertainty: 

                          Due to human error, the uncertainty in the X- axis was 0.2 seconds.

                          The uncertainty in the Y-axis was originally 3 cm because the largest range of measurements was 6 cm (divided by 2= three centimeters.) However, due to the nature of the car, in that it did not drive in a strait line, i had to add a large uncertainty (25cm) to account for the curved path of the tumble buggy. This is also the reason for the presence of a y-intercept (when theoretically there should not be one.) 

Test Reflection

I believe the objective I did the best on was Objective 2 "Can design an experiment with appropriate IV, DV, an constant variables. This was my strongest objective for two reasons. First, the quiz we took earlier in the unit and all of the labs were good review of this objective. Also, this is not new material for me (we have been working on this objective since elementary school.)
The objective I need to improve the most on would be objective 1: "can define and use all vocabulary words correctly." There are a number of words from the list that I am still unsure of how to use (including interpolation & extrapolation.) This objective would be an easy one to work on. In the future, I could look up the words in the textbook and spend some time learning how to use them
The objective sheet was helpful in knowing what was going to be on the test and what vocabulary to study. However, it would have been more helpful if it included examples (or pages in the book where examples could be found.)

IB learner's profile (attempt #2)

The IB Learner Profile

Use the right column to rank your current abilities in each category: (H)igh, (M)edium, or (L)ow

Inquirers	They develop their natural curiosity.  They acquire skills necessary to conduct inquiry and research and show independence in learning.  They actively enjoy learning and this love of learning will be sustained throughout their lives.	M
Knowledgeable	They explore concepts, ideas and issues that have local and global significance.  In so doing, they acquire in-depth knowledge and understanding across a broad and balanced range of disciplines.	L
Thinkers	They exercise initiative in applying thinking skills critically and creatively to recognize and approach complex problems, and make reasoned, ethical decisions.	H
Communicators	They understand and express ideas and information confidently and creatively in more than one language and in a variety of modes of communication.  They work effectively and willingly in collaboration with others.	H
Principled	They act with integrity and honesty, with a strong sense of fairness, justice and respect for the dignity of the individual, groups and communities.  They take responsibility for their own actions and the consequences that accompany them.	H
Open-minded	They understand and appreciate their own cultures and personal histories, and are open to the perspectives, values and traditions of other individuals and communities.  They are accustomed to seeking and evaluating a range of points of view, and are willing to grow form the experience.	H
Caring	They show empathy, compassion and respect towards the needs and feelings of others.  They have a personal commitment to service, and act to make a positive difference to the lives of others and to the environment.	H
Risk-takers	They approach unfamiliar situations and uncertainty with courage and forethought, and have the independence of spirit to explore new roles, ideas and strategies.  They are brave and articulate in defending their beliefs.	M
Balanced	They understand the importance of intellectual, physical and emotional balance to achieve personal well-being for themselves and others.	H
Reflective	They give thoughtful consideration to their own learning and experience.  They are able to assess and understand their strengths and limitations in order to support their learning and personal development.	M

            One category I feel that I particularly embody is the “balanced” category. I enjoy challenging myself in the classroom and work hard to learn the material, get good grades, and find things that I enjoy in school. However, I also realize that the grade I get on my next test or even my overall GPA is not as important as my overall happiness. I am involved in at least two sports every season, as well as working and participating in clubs. While sports take up lots of my time, I have found that it is a good way for me to balance my life and relieve any stress I may have. While I do have to budget my time well and still make sure to keep school as a priority, having lots of extracurricular activities enhances my intellectual well-being, keeps me physically fit, and provides an outlet for better emotional well-being.

            Another area that I feel confident in is the “communicators” category. I am defiantly a “people person” and I often do well working in groups with my peers. The reason I love working in groups is because you have the opportunity to learn from your peers, bounce ideas off each other, and constantly be checking each other. In addition, I believe that the ability to work well in a group that is extremely important in everyday life. For example, many jobs will require you to collaborate with coworkers on different projects, and without the proper communication skills you will not do well in the workplace.  In addition, these communications skills also translate into my everyday life while I am at work dealing with my boss, coworker, and customer I have to have good communication skills; and when I play sports on a team I have to be constantly communicating with them in order to be productive.

            One area that I feel like I could improve is the “knowledgeable” category. Often, I find myself so caught up in whatever topics I am currently learning in my classes that I forget to pay attention to what is going on in the world around me. During this coming year I would like to make it my goal to learn about a wide range of topics. I can do this by watching the news or stopping to read a few interesting newspaper articles each week. I believe by adding more enriching reading materials into my life, (like Bill Bryson’s A Short History of Nearly Everything) I can become more aware of the issues around the world.
