Findings from the psychology of curiosity can be 
profitably employed to guide teaching practice, in a 
range of educational contexts, to motivate students 
to seek information (Pluck and Johnson,2011, p. 29). 
In addition to curiosity, the intrinsic motivation 
of a student is also an important factor in learning. 
Motivation is a dominant factor in influencing the 
learning process. Motivation is the main factor 
driving someone to do something. Therefore, 
motivation is a factor that influences student to 
involveactively in learning. Motivation is a complex 
part of human psychology and behavior that 
influences how individuals choose to invest their 
time, how much energy they exert in any given task, 
how they think and feel about the task, and how long 
they persist at the task (Bakar, 2014). The 
motivation of students in science learning is a point 
as supporting conditions to the central dogma of 
academic performance and critical thinking in 
school science. Moreover, motivation refers to 
reasons that underlie behavior that is characterized 
by the students’ interests, willingness, and volition 
(Beal and Stevens, 2011).According to Ryan and 
Deci (Ryan and Deci,2000), intrinsic motivation is 
defined as doing an activity for its inherent 
satisfaction rather than for some separable 
consequence. When intrinsically motivated, a person 
is moved to act for the external challenge, pressures 
or rewards. 
The Intrinsic motivation can be stronger if given 
outside encouragement. In the learning process, if 
the students perceive the task as something 
interesting, relevant personally, meaningfully, and at 
a level appropriate to the student's abilities, they 
think they can succeed in completing the task. The 
intrinsic motivation will also strengthen if the task is 
connected to by the real world and students have 
control over the task. Teachers support students' 
intrinsic motivation by increasing their curiosity and 
being sensitive to individual differences in 
motivating students (Santrock, 2013).The function 
of intrinsic motivation for students is to encourage 
student learning behavior, influence student learning 
achievement, build learning that is more meaningful 
and motivate the achievement of student learning 
goals. 
The factors of curiosity and motivation are 
equally important factors in achieving the expected 
learning outcomes, one of which is the mastery of 
science process skills. Scientific process skills are 
the result of learning in the form of scientific work 
skills. Abungu (Abungu,2014) states that process 
skills are the centers for procurement of the 
scientific knowledge that is useful for solving 
problems in society. Therefore, the development and 
improvement of students’ process skills become 
matters of importance for the teacher to do for the 
attainment of learning objectives.Scientific process 
skills can also be interpreted as an insight or 
development of intellectual, social, and physical 
skills derived from the fundamental ability that in 
principle exists in the learner (Dimyati and 
Mudjiono, 2006, p. 138).When learners interact in 
the world of science, they find their own research 
through the question, hypothesis, prediction, 
investigation, interpretation, and communication 
stages and these are what are called science process 
skills (Ash, 1998).Process skills could be developed 
through direct experiences as learning experience 
(Rustaman, 2005).  
Rezba et al. (Rezba et al.2007) said that science 
process skills could be divided into two groups, 
namely the basic skills and the integrated skills. The 
basic skills consist of the observation, 
communication, classification, measurement, 
temporary/tentative/initial conclusion (or inference), 
and prediction skills. The integrated skills consist of 
the variable identification, table making, graph 
making, inter-variable relation description, data 
elicitation and processing, investigation analysis, 
hypothesis construction, variable operational 
definition, and investigation and experiment design 
skill. 
All of the science process skills cannot be 
instantly mastered by students. They takes a process 
of habituation and practice.Creating and setting 
learning habits that can grow process skills in 
learners will not be easy.Habits are only possible 
through persistent processes, and sacrifices 
accompanied by ongoing training for consistent 
repetition.It is so difficult to build positive habits 
because every habit must be driven by an 
understanding of knowledge and capable of benefit 
from the behavior. 
Therefore, the factor from within the student is 
an important part to assist the process of habituation, 
such as curiosity and intrinsic motivation of student 
so that the student process skills can be mastered 
properly. 
This study was conducted to see the early interest 
and intrinsic motivation as well as its relationship 
with students' science process skills because 
basically the success or failure of learning depends 
not only on external but also internal factors; both 
factors are equally important.
