Science

What is Science?

An attempt to discover order in nature and use that knowledge to make prediction about what is likely to happen in nature.

What Scientists DO???


Types of Reasoning Scientists Use

Inductive Reasoning

Involves using specific observations and measurements to arrive at a general observationand measurements to arrive at a general conclusion or hypothesis.

Deductive Reasoning

Involve using logic to arrive at a specific conclusion on a generalization of premise.


Example of Experiment: Inductive Reasoning (1)

• You walk into your bedroom at night and flick on the light switch.The light does not come on.

Observation

• Why did the light not come on?

Question• Maybe the

power for the house is out

Hypothesis


Example of Experiment: Inductive Reasoning (2)

• If the power is out, the lights in other rooms should also be out.

Test of Hypothesis

• To check this prediction, go to other rooms and click light switches.

Experiment

• Lights in other rooms come on when their switches are clicked.

Results

• Power to whole house is not out.

Conclusion


Example of Experiment: Deductive Reasoning (1)

• Mimicry of certain fly species (prey) to imitate jumping spiders (predator)

Phenomenon

• Jumping spiders wave their legs in the presence of potential competitors

• Certain fly species, when approached by jumping spiders, wave their wings which have markings that resemble spider legs

Observations• What is

the function of the flies’ wing markings and waving behavior?

Question

• The markings and wing waving increase survival of the flies by causing jumping spiders to flee

Hypothesis



• That the hypothesis is correct

Prediction

• The flies wing markings are masked with a dye

Experiment • Then jumping

spiders should pounce on the experimental flies more often than they do on control flies with normal wing

Predicted Result

• ConclusionIs the hypothesis about the wing markings correct?

Conclusion

Hierarchy of Scientific ConfidenceBI1201 Pengantar Sains dan Teknologi Hayati

Synthesis of a large body of information that encompasses well-tested and verified hypotheses about certain aspect of the natural world.

Evolves in redefinition and refinement.

SYSTEM THINKING

What is Systems Thinking?

Scientific field of knowledge for understanding change and complexity through the study of dynamic cause and effect over time.

As paradigm, it’s a way of thinking about the world and relationship.

Systems Thinking

Forest Thinking

Dynamic Thinking

Operational Thinking

Closed-loop Thinking

Group Model Building


Principles in Systems Thinking

•The art of seeing the forest and the trees; the whole is more than the sum of its part. Any problem is related to the larger forces and interactions.

Big Picture

• While habitual short-term fixes can impede long-term outcomes, one cannot ignore necessary short-term measures.

Short and Long Term

• There is more to a system than can be measured by conventional performance indicators, known as Key Performance Indicator (KPI), Critical Success Factor (CSF), Balanced Score Card (BSC).

Soft Indicators

• A great deal of problems encountered by organizations are created internally.

• We contribute to our own problems not only because of the unintended consequences but also because of our mental models.

System as a Cause

• Cause and effect are often not close in time and space.

• Time delays and chain effects of actions often mask the connection between cause and effect.

Time and Space

• Common confussion between cause and symptom of problem leads to inappropriate treatment.

Cause vs. Symptom

• Complex problem or decisions are often presented as either-or choises.

• Yet, modern sciences suggests that reality is a potential with multiple outcomes.Either-Or Thinking


Systems vs. Linear Thinking

Systems Thinking ≠ Conventional Linear Thinking

System thinking involves:

• Dependent factors

• Loops of causes and symptoms; casuality is often circular.

• Factors are often not equally important; it could be even hierarchical.


Critical thinking is a skill

Critical thinking is the capacity to distinguish between beliefs (what we think is true) and knowledge (facts that are backed by accurate observation) helps us separate judgment from facts

Critical thinking involves subjecting facts and conclusions to careful analysis, looking for weaknesses in logic and other errors or reasoning

There is no single formula on how to think critically

Critical Thinking Skill


Why Do I Need to Think Critically?

Prof. Karen J. Warren of Macalester College suggests the following list :

1. Skepticism and independence

2. Open-mindedness and flexibility

3. Contextual sensitivity and empathy

4. Accuracy and orderliness

5. Persistence and relevance

6. Decisiveness and courage

7. Humility


CONCEPTS & RULES

Concept 1

Critical thinking requires one to know as much information about an issue as possible before rendering an opinion or making a decision.

Rule 1

Gather all information :

• Dig deeper

• Learn all you can before you decide

• Don’t mistake ignorance for perspective


CONCEPTS & RULES

Concept 2

To think critically about an issue, one must understand the terms and concepts related to it.

Rule 2

Understand all terms

• Define all terms you use

• Be sure you understand terms and concepts others use


CONCEPTS & RULES

Concept 3

Critical thinking requires that we know how information has been acquired and that we question the methods by which it was derived.

Rule 3

Questions how information is derived.• Were they derived from

scientific study?• Were the studies well

conceived and carried out?• Were there an adequate

number of subjects?• Was there a control group

and an experiment group?• Has the study been

repeated successfully?• Is the information

anecdotal?


CONCEPTS & RULES

Concept 4

Critical thinking requires one to search for hidden biases and assumptions that may influence one’s understanding of an issue or interpretation of data.

Rule 4

Question the source of information.

• Is the source invested in the outcome of the issue?

• Is the source biased?

• Do underlying assumptions affect the viewpoint of the source?


CONCEPTS & RULES

Concept 5

Critical thinking requires us to question the conclusion drawn from facts to see if other interpretations might be possible.

Rule 5

Question the conclusion.

• Do the facts support the conclusion?

• Correlation does not necessarily mean causation


CONCEPTS & RULES

Concept 6

Our knowledge of the world around us is evolving, so it is necessary to accept uncertainty as an inevitable fact of life and make decisions with the best information possible.

Rule 6

Expect and tolerate uncertainty.

• Hard and fast answers aren’t always possible

• Learn to be comfortable with not knowing


CONCEPTS & RULES

Concept 7

To become a critical thinker it is necessary to examine the big picture -relationships and entire system.

Rule 7

Examine the big picture.

• Study the whole system

• Look for hidden causes and effects

• Avoid simplistic thinking

• Avoid dualistic thinking


Assignment

1. What’s the difference between scientific inquiry and non-scientific inquiry?

2. From your opinion, which one would be better for understanding life sciences and technology, system thinking or linear thinking? State your arguments.

3. What is the relationship between systems thinking and critical thinking? Elaborate your answer.
