1. INTRODUCTION
A school is a place where formal education takes place and a place to get an education in various
knowledge. Physics is one part of Natural Sciences or known as science. Science is a process.
Boat Prototype as Teaching Material on STEM Based Education to Enhance the High Order
Thinking Skills
http://www.iaeme.com/IJARET/index.asp 391 [email protected]
It is a series of structured and systematic activities carried out to find concepts, principles, and
laws about natural phenomena, including the ability to think, to compile, and to discover new
concepts. At present, science and technology are being developed so rapidly that it has an
impact on the development of methods and learning media in the world of education, especially
in the development of teaching materials. The education system is increasingly focused on 21st-
century learning that provides educational reform movements, especially in the fields of science
and mathematics.
Science learning with the STEM approach trains students to think critically, creatively,
collaborate, and communicate. Therefore, the learning premises n approach to STEM support
the demands of education in the face of the 21st century that is also the target of competencies
in the curriculum of 2013. The 21st Century Learning is learning that integrates literacy,
knowledge, skills, and attitudes, as well as mastery of technology. The skills needed in the 21st
Century are the Higher Order Thinking Skills (HOTS) that are very much needed in preparing
students to face global challenges.
Thus, the learning process that allows students to have higher-order thinking skills (HOTS),
among others, by using STEM-based science teaching materials on the application of Newton's
third law and the law of conservation of momentum. This teaching material contains guidelines
for teachers in presenting learning material, the application of Newton's third law, and the law
of conservation of momentum. This learning design is using the STEM approach: Science,
Technology, Engineering, and Mathematics. Through learning that uses STEM-based teaching
materials, students learn about science, technology, engineering, and mathematics. Therefore
students become problem solvers, innovators, creators, and collaborators and continue to fill
the critical paths of engineers, scientists, and innovators that are very important for the future.
STEM-based learning trains high-level students' thinking skills (HOTS).
According to Minister of Education and Culture (Kompas, 09 November 2018), urges
teachers to continue developing learning in schools with higher-order thinking skills (HOTS)
models. The development of this model will foster children to think critically, communicate
well, collaborate, think creatively, and be confident in preparing for the millennium era.
Teaching Materials developed by teachers at this time include modules and worksheets
learners ( LKPD ) are arranged separately. Most teaching materials developed have not
integrated or combined science, technology, engineering, and mathematics. Recently, teaching
materials are still dominated by teaching materials in the form of models or practice books.
These books are packaged in the form of a summary of material for one semester. Teaching
materials that train students in critical thinking, creative, collaborating, communicating (4C),
and 21st-century skills are still rare both in their use and development.
Based on the above background, researchers create the development of STEM - based
science teaching materials. The researchers hope that students will quickly understand the
material and have high-level thinking skills (HOTS), empower them to think critically,
creatively, collaborate, communicate, and 21st-century skills. The innovation of this study is
"Science-Based Instructional Materials Development STEM to Improve the Higher-Order
Thinking Skills (HOTS) by using Boat Prototype."
2. THEORETICAL FRAMEWORK
2.1. STEM Based - Science Teaching Materials
Teaching materials are all forms of materials that help teachers/ instructors in carrying out
activities to learn to teach in the classroom. (Ministry of National Education, 2008). In other
words, the material taught is a tool or a means of learning which contains the materials,
methods, limitations, and how to evaluate which designed as a systematic and attractive to
Ngadinem, Dwi Sulisworo and Ishafit
http://www.iaeme.com/IJARET/index.asp 392 [email protected]
achieve competency goals. Teaching materials will decrease the burden of teachers in
presenting the material (face to face) so that the teacher has much time to guide and assist the
participant students in the process of learning. Teaching materials are useful to help educators
in carrying out learning activities. (Nurdyansyah, 2015)
Teaching materials of science wth STEM - based provides opportunities for teachers to
demonstrate to students how the concepts, principles, and techniques of science, technology,
engineering, and mathematics used in an integrated way in the development of products,
processes, and systems in their daily lives. Therefore, adopting the definition of education
STEM as an interdisciplinary approach to learning, in which students use science, technology,
engineering, and mathematics in real contexts that connect between school, work, and global
world, thus developing literacy, STEM gives the ability of students to compete in a new
economic era based on knowledge. (according to Reeve, 2013 quoted by Harry Firman, 2015).
2.2. STEM Learning Model PJBL
The characteristics of STEM learning are integrating science, technology, engineering, and
mathematics in solving real problems. However, there are a variety of ways used in practice to
integrate STEM disciplines, and the pattern and degree of cohesiveness depend on many factors.
Presentation of learning with the STEM approach must meet several aspects of Scientific,
Engineering Practice, and illustrate the existence of Crosscutting Concepts or slices of concepts
among scientific knowledge, technology, engineering, and mathematics. Learning Design with
topics Newton's Law III and the Law of Conservation of Momentum done with the STEM
approach.
The Project-Based Learning (PjBL) model is a recommended model for implementing the
2013 Curriculum, while STEM is a learning strategy. STEM learning emphasizes the process of
designing, engineering, or engineering. Stages of the process/step learning STEM PPP
presented in Table 1:
Table 1 Stages of the STEM PjBL learning process/step
STEM PjBL Steps Description
Reflection
The First Stage is to bring students into the problem and provide
inspiration to the students in order to be able to begin to
investigate immediately. This phase intended to connect what is
known and what to learn.
Research
A second stage is a form of student research. Teachers provide
learning materials, selecting readings, or methods other to collect
relevant source information. The learning process occurs more
and more during this stage, the progress of student learning
concretizes a conceptual understanding of the problem. During
the research phase, teachers more often guide discussions to
determine whether students have developed conceptual and
relevant understanding based on projects.
Discovery
Stage invention generally involves the process of bridging the
research and information that known in the preparation of the
project, when students begin to learn independently and
determine what are still not known. Model of STEM PPA divides
the students into groups to present a possible solution for
problems, collaboration, and cooperation among friends in
developing the ability to build a habit of mind of the process of
designing.
Application The application aims to test the product/solution in solving
problems. In some cases, students test a product made of the
Boat Prototype as Teaching Material on STEM Based Education to Enhance the High Order
Thinking Skills

provisions set in advance. The results obtained to fix the step
before. Stages The students learn the context of the more
comprehensive in the outer STEM or connect between
disciplinary fields of STEM.
Communication
The final stage of each project is making products/solutions by
communicating between friends and the scope of the class. The
presentation is an essential step in the process of learning to
develop communication and collaboration skills, as well as the
ability to accept and implement feedback through the
construction.

Also, Higher Order Thinking Skills become a necessity in both learning and assessment.
The essential competency achievement through this learning is KD. 3.7 Analyzing the
interaction of forces and the relationship between force, mass, and the movement of objects in
straight motion and KD. 4.7 experiment and present the results related to the interaction of
forces and the relationship of force, mass, and acceleration in straight motion and their physical
meaning. KD. 3.10 Applying the concept of momentum and impulses, and the law of
conservation of momentum in everyday life and KD. 4.10 Presents the results of testing the
application of the law of conservation of momentum, for example, a free-falling ball to the floor
and a simple rocket. Before learning approach STEM, learners must master the prerequisite
concepts such as expansion, Newton Law, and the law of conservation of momentum. There is
a positive relationship between knowledge of science, technology, engineering, and
mathematics on the subjects of boat prototypes. It described as follows: science: scientific
knowledge which is obtained by the students consists of a concept third Newton Law and the
law of conservation of momentum. Technology trained with students to building prototypes of
boats by problem-solving needs. Engineering in this learning trains students to engineer simple
boat prototypes with Newton's third law principles. Mathematics: mathematics in this study is
used in the process of engineering boat components so that they are balanced, able to move,
and calculate the mass of candles needed to cover a distance of 1 meter.
This teaching-learning material prepared as a guide for Physics teachers in high school
develops learning planning, implementation, and assessment. Teaching materials consist of
three parts: Part I: Introduction: contains a general description, STEM learning on the topic boat
prototyping, a description of the teaching-learning materials in shipbuilding. Part II Study with
STEM approach contains necessary competencies and indicators of achievement of
competencies, learning objectives, material analysis of learning with STEM instructional
design, capability requirements, the development of 21st-century skills, development
strengthening character education, learning scenarios, learning resources, tools, and materials.
Part III Assessment of learning techniques and forms of assessment, assessment tools, and
worksheets for participants.
2.3. High Order Thinking Skills (HOTS)
Higher Order Thinking Skills ( HOTS) ) recognized from Benjamin S. Bloom concept et al. in
the book entitled Taxonomy of Educational Objectives: The Classification of Educational Goals
(1956) to categorize levels of thought called Bloom taxonomy, starts from the lowest to the
highest. The concept of this is the goals of learning divided into three domains, namely
cognitive (knowledge), affective (the emotion surrounding the attitudes and feelings ), and
psychometrics ( ability physical as skills). The concept taxonomy to determine the purpose of
learning this can we refer to as the destination end of a process of learning. After the process of
particular learning, students expected to adopt the skills, knowledge, as well as the attitude.
Ngadinem, Dwi Sulisworo and Ishafit
http://www.iaeme.com/IJARET/index.asp 394 [email protected]
HOTS itself is part of the realm of cognitive that exist in taxonomy Bloom and aims to
sharpen the knowledge. The realm of a cognitive version of Bloom's later revised by Lorin Ande
and David Karthwohl. The levels of thought transformed into six, namely: remembering,
understanding), applying, analyzing, evaluating, and creating. Levels 1 to 3 are categorized as
low-level thinking ability (LOTS), while levels 4 to 6 categorized as high-level thinking ability
(HOTS).
General Director of Learning and Student Affairs Kemenristekdikti, Prof. Intan Ahmad,
Ph.D., said that the purpose of HOTS is to test students in analyzing, comparing, calculating,
and so on. "So it is the necessary capabilities. Not only just to remember or memorize the
course". Prof. Diamond in Ruangguru said LIVE Special SBMPTN on Tuesday, 30 October
2018.
HOTS Problem is encouraging learners to perform level high reasoning so as not fixated
only on the pattern of answers that resulted from the process of memorization, without knowing
the concept of knowledge. HOTS is one of the skills demands in 21-st century learning, namely
critical thinking, creative.

Table 3 Implementation Process STEM PPA At Teaching Learning Activities
Stage 1: Reflection
The teacher displays a series of pictures about the launch of a rocket and a boat. Teachers provide
questions ill-defined problems on the principle of work launching rockets and ships boat. Participants
answered questions stimulant. The teacher conveys problems regarding the project of making a simple
boat prototype
Stage 2: Research
Participants gather information about the making of the simple model boat. The teacher guides
students to be able to apply the concept of Newton's third law and the law of conservation of
momentum in the completion of the project with the help of LKPD. Participants students discuss to
find a solution to the problem of the manufacture of the model ship boat
Stage 3: The discovery
Participants students discuss making the design of a model of simple boat, determining the selection of
tools and materials t used in the making of the project. Teachers emphasize the Engineering Design
Process in a project that made participants. A teacher asks participants learners to write down all
which are being planned / ideas from each member that appears. Participants determine the design of
the model boat is simple; the best results of the discussion groups and describe the design by the
guidelines that are in LKPD. Participants students are flocking to present the results of the design of
the model ship boat simple
Stage 4: Application
Participants students create and test the design of the boat at home and school through working groups
according to LKPD that has been distributed. Participants students perform measurements of the mass
of wax that required a boat cover a distance of one meter. Teachers informed students to document the
entire process of manufacture and test try a model of simple boat. Participants students fill out sheets
ratings themselves and ratings among friends when doing work group making of a model ship boat
simple
Stage 5: Communication
Teachers convey the rules of technical presentations. Participants are students presented the results of
a project tested to try and emphasize the persuasive communication. Teachers provide an opportunity
to ask the group of others, monitoring the course of the presentation of the group. If required, the
participant students test to try the product in school. The teacher asks each participant students to
choose products boat the best of the group other.
Implementing teaching materials of STEM in the process of learning is done by a physics
teacher, 33 participants of class X MIPA, in one of the high schools in Yogyakarta. The
allocation of time for learning requires six face-to-face hours of learning and the provision of
duty (project) at home. Implementation of learning begins with the provision of the pre-test.
The objective of implementation is to determine the attainment of skills HOTS before the
implementation of the material taught. The re-test uses the HOTS question instrument, which
contains cognitive levels analyzing (C4), evaluating (C5), and creating (C6). Instruments for
pre-test and post-test have been validated by materials and media experts. Next, the learning
stage is the implementation reflection, research, discovery, communication, ratings themselves,
ratings among friends, and ends with post-test. During the process of learning, the teacher did
a discussion vote, assessment presentation, the assessor 's project, and assessment products. The
post-test aims to determine the achievement of HOTS after the implementation of teaching
materials. The implementation of STEM teaching materials in the learning process is presented
in Figure 6.
