What I found the most interesting this week is the section
on Evaluating Scientific Hypotheses. The criteria for evaluating hypotheses
include the use of precise language and providing a testable explanation and relevance
to the problem that is studied because we can’t just include everything we
observe. In other words, there needs to be a focus in the study. The criteria
also include consistency, meaning that the scientific explanations should be
consistent with the “facts” in that field. An example given in the book is the
release of methane in the ocean as a cause of global warming. This is
considered a good hypothesis because it corresponds to the known and accepted
idea that global warming is a result of both mankind and physical, natural
changes on earth. Another part of the criteria is simplicity which in its name
explains what it really is. Scientists basically choose the simpler hypothesis
when there are rival hypotheses. Furthermore, the criteria also include
testability and falsifiability. Studies should be testable in that they can be
replicated by other scientists because science is a continuous, changing
process where people find more discoveries. An explanation must also be
falsified. An example that makes falsifying an explanation easier is the one
given in the book where they’ve hypothesized that all swans are white, when
really there are also black swans. Lastly, a good hypothesis should also have a
predictive power, meaning that this explanation can be used to predict or
explain similar events.

Week 11/12: Ch. 12 Question 2
An observation I can think of is when I hear other people
speak a language different from mine. For instance, I was in a restaurant or a
salon once and the people around were speaking some other language. I thought
they were mad because they were speaking quite loudly that it almost seemed
like they were yelling at each other. I was just listening and looking at some
of their faces which appeared to be a bit serious. But then seconds after I had
concluded that there was bad blood between them, they all started laughing
about something! So, that was definitely a situation where a conclusion I made
had been incorrect. Thinking scientifically did not really come to mind then
because I was pretty much misjudging them. I guess how I could apply science to
this is by asking myself questions and thinking of the situation first before
making an assumption or a hypothesis. I should observe them well first or
consider other possible hypotheses before concluding that they were angry at
each other. I guess I can also apply the idea of empiricism which means that we
can gain knowledge just through our senses (since I listened to them and
watched their expressions).

Week 11/12: Ch. 12 Question 1
“You are feeling like a doormat -- but not everyone sees you
that way! In fact, your great energy helps you to say no just as often as you
should. You may need to adjust your expectations.” (Yahoo Horoscope for Pisces November
13, 2012)
Firstly, I am not
feeling like a doormat! I have not interacted with enough people today to feel
like I have been used or that I give in easily to what people tell me to do. However, a friend did text me yesterday,
asking me to work with her on an essay that is due next Monday. I know that she
is fully capable of writing it on her own and just wants to work with me to
make it easier for her. For our first essay, we worked together because she
didn’t get to read the book since she enrolled late to class. That was
acceptable because obviously she needed help. But for this paper, we’ve been
reading a Superman comic book that she should’ve been reading as well so why
does she need my help? It’s only a 3-4 page paper on Superman, for goodness’
sake! Anyway, I’m getting all enraged here. I said “no, I can’t help you this
time” not just because I knew that she could do in on her own, but I have so
much stuff due for other classes.
So, creepily enough, this horoscope somehow applies to my
situation. But like mentioned in the book, horoscopes are usually so vague that
they could apply to most people’s situations. The prediction is definitely
falsifiable because this all happened yesterday.
Plus, I’m not necessarily feeling like a doormat. I haven’t given in to
anything today. I just went to school and went back home. Lol.

Week 11/5: Ch. 11 Question 3
The section I found most interesting this week is the part
on Science Reporting. As a student studying pre-nursing, I always have science
classes and have done papers where I had to interpret scientific information. Therefore,
I appreciate it when scientific findings are reliable. The subsection,
“Misinterpretation of Scientific Findings,” discusses how reporters do not have
a background in studying science and how they can misinform us about scientific
studies. Boss also mentions how scientific information can also be
sensationalized and be biased in terms of gender and culture and also how not
all the information about scientific studies is reported to the public. The
subsection “Government Influence and Bias” discusses how the government can
control the scientific reports and distort them. An example in the book is how
US officials reported that the dangers of the chemical dioxin were exaggerated
when it really is a dangerous chemical. Therefore, because of all this
misinformation that can occur, we need to evaluate scientific research. We need
to look at the credentials of the sources, proper citation, experts’ opinions,
and if the report is biased or not.
Week 11/5: Ch. 11 Question 2
Hunt believes that the teaching methods only encourage
plagiarism. He mentions how the concept of grading a student’s work puts
pressure upon the student and also, how teachers just evaluate grammar and
organization in a paper and not the actual message or content itself.
Sadler argues that plagiarism is not acceptable and
institutions should apply stricter rules and punishment when a student commits
plagiarism. She states her ten reasons why she thinks plagiarism is detrimental
(theft, breaking the trust between the student and the teacher, influence the
cheater later in life, etc.). She is very clear and strong in her position. At
the end of the reading, she states that students should be informed about the
consequences of plagiarism and should be taught how to cite correctly.
I think Sadler makes the best argument. Hunt sometimes
addresses himself in the reading or uses a lot of analogies instead of focusing
on the subject like students or teachers. The analogies he uses are kind of
unnecessary. It’s like he needs analogies to explain something instead of just being
direct. Hunt also generalizes that students are just “avoiding something
negative” when we write essays unlike scholars who have deeper reasons. On the
other hand, Sadler’s pretty clear on her stance and simply states her reasons.

Week 11/5: Ch. 11 Question 1
A form of media usually is biased or promotes only one view,
and so if I believe something and a certain television show or newspaper
article agrees with what I believe, then that only reinforces my existing
worldviews. For instance, I think that gay marriage should be allowed. I would sometimes watch the Ellen Degeneres show
and I remember episodes where she would promote gay marriage or Obama. I would
agree with her as well and my belief in gay marriage as an acceptable thing is
only reinforced by her belief in it too. The media can also expand our views,
however, and not just limit us to our own beliefs. For example, when I read an
article online like Time or Yahoo, I always read the comments. These comments
from various people with various beliefs can definitely influence my opinions
as well. They open my mind to other views or information. The media can also so
easily distort information that it can be challenging to choose who or what to
believe. Just like the example given on the book, with NBC and FOX promoting a
certain candidate. Of course, these networks would both say the good things
about the candidates and so, it makes it hard to believe who deserves the
position. In the text, it also mentioned people paying the media to advertise
or promote them. This is another way the media can challenge our views because
how do we really know who to believe then if people might be doing this behind
our backs.
