1 THE NATURE OF SCIENCE A paper for a session of the SEAQIS Training on Science Classroom Supervision, 2020 Dr. Harry Firman harry.firman@hotmail.com Abstract Science have two dimensions, i.e. dynamic dimension and static dimension. Dynamic dimension deals with the ways of scientists investigate such as observation, experiment, data collection and interpretation, whereas static dimension covers many kinds scientific knowledge as product of investigations, such as scientific facts, concepts, laws, and theories. Both dimensions of science need to be considered equally important in science learning. Scientific knowledge is characterized as empirical based, tentative, limited, imaginative and creative, tested, parsimony, and subjective in a certain aspect. Keywords: Nature of science, scientific investigation, scientific knowledge 1. Introduction Many of us look at the science (natural science) as a collection of knowledge (facts, concepts, laws, theories) about natural phenomena. Such thoughts are not wrong, but less complete. Basically, science has two dimensions, namely "dynamic dimensions" and "static dimensions" (Mannoia, 1980:5). The dynamic dimension of the science describes science as a research (investigation) activities or scientific inquiry using scientific methods, which relies on scientific process skills, such as observation, data- gust, classification, experimentation, etc.). Meanwhile, the static dimension of science describes science as a product of ideas system (scientific knowledge), which is basically a product of scientific investigation. Therefore, it can be said that the science is processes (scientific investigation) and products (science knowledge). Products of science are actually result of processes of science, as illustrated in Figure 1. Science Process (Ways of finding out) Science Products (System of ideas) Observation → Facts Collection and recording (data) → Data Classification → Concept Experiments → Law, principles, rules Figure 1.
