INTRODUCTION TO SCIENCE, TECHNOLOGY AND SOCIETY Flashcards
Defined as the teaching and learning of science
in the context of human experience
SCIENCE-TECHNOLOGY-SOCIETY
SCIENCE-TECHNOLOGY-SOCIETY
Called the ———– in science education’
‘megatrend
‘paradigm shift for the field of science
education’
SCIENCE-TECHNOLOGY-SOCIETY
Central goal for Science education
SCIENCE-TECHNOLOGY-SOCIETY
involves a
series of steps that
are used to
investigate a natural
occurrence.
Scientific
Method
6 STEPS BASED ON SCIENTIFIC METHODS OR TO SOLVE A PROBLEM
ICFTAR
- Identify the Problem
- Collect Information/Research
- Form a Hypothesis
- Test Your Hypothesis – “Experiment”
- Accept or Reject Your Hypothesis – “Analysis”
- Report Your Results – “Conclusion”
State the problem to be solved or the question to be answered.
Identify the Problem
Obtain facts and ideas from books, journals, internet, etc. that provide insight
regarding your problem/question. Cite these resources.
Collect Information/Research
Based on the information/research you collect, propose a solution or “best guess”
that will help guide your experimentation and attempt to answer the proposed
problem/question.
Form a Hypothesis
Describe, design, and conduct an experiment that will give you information or
data that supports (or not) your hypothesis.
Test Your Hypothesis – “Experiment”
Determine whether your data/results from the experiment supports (or not) your
hypothesis; if not, it may be necessary to review your information/research and
revise your hypothesis.
Accept or Reject Your Hypothesis – “Analysis”
Formulate a conclusion that answers the original question from step one and
share the results with the scientific community (or the community at large).
Report Your Results – “Conclusion”
data that are descriptions of qualities such as shape, color, taste,
feel, etc…
acquired by using your senses
Observations
2 TYPES OF Observations
Objective observation
Subjective observation
an observation based on opinion
SUBJECTIVE
an observation based on fact
Objective
a piece of information that can be strictly defined and proved true.
fact
a statement that expresses a belief, value, or feeling
opinion
Which type of observations should be used in science?
Objective observations should be used in science
because they are based on facts and the basis of
science is to identify the facts!
an explanation that tries to make sense of your observations
influenced by your experiences/prior knowledge
these explanations may not be true
Inference
Example
Observation:
John was breathing heavily as he walked into the classroom.
Possible Inferences:
He ran to class because he was going to be late
He just played basketball in gym
a working explanation or trial answer to a problem
an “educated guess”
Hypothesis
can be written in the form of an “If…, then…, because…” statement
is not necessarily proven correct just because data/results from one
experiment supports it
Hypothesis
when repeatedly supported by the same results 🡪 theories 🡪 laws
Hypothesis
factual information
data
types of data
Quanti and quali
data consisting of numbers
quanti
data consisting of verbal descriptions or information gathered using
scales without numbers
quali
experimental tests done more than once
necessary to provide more accurate results; data is averaged together
lessens the impact of a chance error on the experimental results
Repeated Trials
things that can be assigned or take on different values
in an experiment
any factor that can change
variables
types of variables
Independent
- Dependent
variables that may change as a result of the independent variable
the factor you measure to gather results
usually expressed after the word “then” in the hypothesis
could be thought of as the “effect” in a cause and effect relationship
Dependent
variables that are purposely changed or manipulated in an experiment
the factor that you wish to test
usually expressed after the word “if” in the hypothesis
could be thought of as the “cause” in a cause and effect relationship
Independent
a group of subjects in an experiment that are not given any
special treatment
something that is not manipulated
Control or Control Group
same as the experimental group in every possible way,
except for the factor being tested
a neutral point of reference for comparison – it allows you to
see what changing a variable does by comparing it to not
changing anything.
Control or Control Group
- An explanation that ties together many hypotheses and observations.
- Supported by repeated trials.
- May help with further predictions.
- Tells why it happens.
scientific theory
- A summary of many experimental results and observations.
- Tells how things work
- Only tells what happens, it does not explain why.
