Irfandi Rudin The steps in solving a problem, including understanding the problem, planning a solution, implementing the plan, and evaluating the solution .
In the educational context, problem-solving skills are considered highly important because they serve as a foundation for developing other skills such as critical, analytical, and creative thinking.
This statement aligns with the research .
, which states that problem-solving skills is a high-level cognitive skill that enables students to acquire knowledge and skills.
Problem-solving is a complex skill as it requires individuals to employ high-level thinking skills in addressing challenges .
Therefore, this skill is highly vital due to its broad relevance in everyday life .
Physics, as a discipline rooted in natural principles, has a close relationship with the surrounding reality, making problem-solving skills in the context of physics learning equally important for learners.
In the context of the classroom learning process, instructional models play a crucial role.
Instructional models serve as frameworks or plans used to develop long-term curricula, design instructional materials, and provide guidance in the classroom or other learning environments .
Instructional models have a structure that provides clarity in the learning process, making it systematic and Choosing the appropriate instructional model can help achieve the skills desired by Instructional models can be selected based on the learning needs to achieve desired Instructional models provide guidance for teachers in organizing the learning process in the classroom.
Alongside this, teachers are faced with the demand to provide effective teaching that benefits both themselves and the students .
Instructional models also play a significant role in shaping various skills that learners will acquire.
In efforts to enhance problem-solving skills, there are various instructional models that can be utilized, and numerous studies have explored this.
For example, instructional models like Problem-Based Learning (PBL) have been proven to help improve students' problem-solving abilities.
The use of PBL has been found to bring about significant improvements in various aspects such as learning attitudes, decision-making, problem-solving skills, critical thinking, and motivation .
Based on observation results in the classroom learning process, instructional models are often accompanied by specific approaches or learning strategies.
One recommended learning strategy is the differentiation approach.
Differentiation approach is a teaching strategy that adjusts the learning method according to students' interests, learning preferences, and readiness, with the aim of improving learning outcomes .
The use of differentiation approach is based on an understanding of individual learning styles, which can be identified using validated software.
Students' learning styles can be grouped into three main types: visual, auditory, and kinesthetic .
The role of these learning styles is significant in the learning process because students are often forced to learn using methods that do not match their learning styles, which can hinder their concentration when information is delivered by the teacher.
Therefore, students' learning styles have a significant impact on their learning outcomes.
In addition to instructional models, teaching materials, and learning media also play a crucial role in the learning process.
With the advancement of technology, the use of technology has significantly impacted the evolution of teaching materials.
One striking example is the shift from print books to electronic books, more commonly known as e-books, as a learning resource for learners.
The use of ebooks is increasingly popular due to their convenience, affordability, and ability to present meaningful E-books provide opportunities to transform difficult learning into a more dynamic process by actively applying knowledge and skills through multimedia and interactive approaches .
Furthermore, e-books can be designed as learning media used to enhance specific abilities or skills, such as problem-solving skills for learners.

The use of Ebook based on learning style is quite helpful for students to improve problem solving skills.
In the modeling and implementation class, there are several students who have not reached the average standard on the problem-solving skills test.
There are several factors that may cause this.
One of them is the lack of dedication from students in following the lesson, leading to their daily experiences.
Additionally, there is a possibility that students do not access the E-book according to their learning This deficiency has the potential to hinder studentsAo ability to solve problems.
From the other side, the use of E-books that are adapted to learning styles and integrated with problem-based learning (PBL) models can significantly improve studentsAo problem-solving skills.
Implementing problem-based learning as a teaching approach can effectively improve studentsAo skills in problem solving.
This study aims to improve studentsAo problem -solving skills through the use of physics E-boos that are adapted to individual learning styles.
With improved problem-solving skills, students can better comprehend the material taught by teachers and tackle challenges related to global warming issues, both in academic and non-academic contexts.
In the learning activities, both in the modeling and implementation classes, the classes are divided into several study groups based on the results of the previous learning style tests.
E-books are distributed through the student chat groups in both classes.
Students participate in the learning process with the assistance of student worksheets (LKPD) and use physics E-books that are adapted to their learning style as the main source of material.
