Research Article

The article I chose is the Key to Teaching the Nature of Science by William F. McComas. This article talks about the  Nine core Nature of Science (NOS) Ideas. I have listed them below:

  • Science demands and relies on empirical evidence
    • Science should required data which is reviewed by others. This data should justify all final conclusions.
    • Ideas begin as "exploratory notions" 
      • Can not be dismissed immediately unless there is significant evidence stating otherwise.
    • "The requirement for empirical evidence is accompanied by the caution that not all evidence is gained through experimental means, although that is frequently called the "gold standard" of science". 
    • Science relies on basic observations
    • Scientists use a combination of methods such as:
      • historical
      • observational
      • experimental
    • Science is and must remain an "empirical data-driven pursuit.

  • Knowledge production in science includes many common features and shared habits of mind. However, in spite of such commonalities there is no single step-by-step scientific method by which all science is done.
    • Logical reasoning and data collection are essential to science
      • However, there is no universal way
    • "Studies of scientists at work reveal many idiosyncratic ways of approaching research and even coming up with research in the first place"

  • Scientific knowledge is tentative but durable. This means that science cannot prove anything because the problem of induction makes "proof; impossible, but scientific conclusions are still valuable and long lasting because if the way that knowledge eventually comes to be accepted in science". 
    • `"Induction is the knowledge generation process by which individual data points related to the problem or phenomenon are gathered until a general trend, principle or law emerges from this mass of data" 
    • Prediction and deduction are essentials, as they are used to determine the validity of the  conclusion. 
      • There is no way to determine whether the statement is true, only time can tell.

  • Laws and theories are related but distinct kinds of scientific knowledge.
    • Misconception: Science is laws of mature theories and laws are more valuable than these theories.
      • Laws and theories are equally important
    • Laws: generalizations or patterns in nature
    • Theories: explanations for why laws hold

  • Science is a highly creative endeavor
    • Scientists agree that their work is creative
      • inspiration leads to the creation of science
    • We have to teach students that science is not just facts
      • they should explore the world of science
        • Studies show that students will reject the field of science  as a career because they had no opportunity to explore or see the creativity it implies 

  • Science has a subjective element
    • Science is subjective
      • People respond and evaluate data in different ways
    • Therefore, ideas, data and conclusions must be peer reviewed in order to be published
      • Acts as a checks and balances system

  • There are historical, cultural and social influence on science
    • Research may favor certain aspects or these aspects may favor certain research 
      • May be controversial 
      • These aspects may impede or support the research

  • Science and technology impact each other, but they are not the same
    • Topics are technological in nature or scientific in nature
      • Technological topics are often "applied science"
      • Science in natural are "pure science"

  • Science and its methods cannot answer all questions
    • There are limits to science
      • can not explain the opinions of people
    • Avoid the common but false idea that science and religion are at war
    • Important: Science cannot and should not answer all questions

What is Space Science?

Image
Space science includes space exploration and the study of space, also known as astronomy.  Astronomy is the study of the sun, moon, stars, etc. Often times, people associate astronomy with astrology. However, they are far different. As mentioned, Astronomy is the study of space. Astrology is the study of the positions, motions and properties of celestial objects and how they affect people and events. Astrology is no longer considered to be a science. Astronomy is one of the oldest scientists known to man. It dates as far back as the ancient civilizations of Mesopotamia and the Mayans.  While there was not the advanced technology that we have today, they were still able to observe space with their eyes. Galileo Galilei was one of the scientists who improved the technology of the telescope, allowing closer observations of the planets.  Isaac Newton explained the physics that made up our solar system and the reasoning for gravity. There are several fields of astr...

The five E's of Inquiry

What are the five E's of Inquiry?? (A constructivist approach to learning) Engage--> An engaging activity Making connections with their prior knowledge Anticipate activities and focus students' thinking on learning! Make them mentally engaged! Explore--> Provides students with a common base of experiences. develop concepts, process and skills exploration of environment and materials Explain--> Helps students to explain the concepts they are using verbalize their understanding demonstrate new skills introduction of terms, definitions, and  explanations Elaborate--> extends students' understanding practice of skills and behaviors develop deeper and broader understanding of major concept obtain additional information Evaluate--> encourages learners to assess their understanding assess abilities evaluation of students

Summary on NASA Article (Soft robotics)

Image
NASA is now attempting to develop "soft robots" to explore other worlds. These soft robots does not have rigid pieces. They are flexible and able to develop to new and different environments. They are able to expand their range of motion and squeeze into tight areas if needed. This development however, is still in its early stages, but NASA scientists are continuing to develop and research how these soft robots are to be used in future space missions. The material of these robots are able to flex and relax, similar to the muscle of a human being. The scientists are currently investigating the following areas; mobility, joining, leveling and shaping.  Once they are able to overcome the hurdles in those four areas, they must find out one how to combine they together. NASA is continuing to research and develop these robotics and are planning to have their interns work over the summer and adjust to the feedback. Attached here is a video about the soft robotics: Lin...
