Abstract

This research stemmed from the need to improve the teaching and learning process of Natural Sciences, given the limited use of digital tools, the scarce application of active methodologies, and the persistence of traditional practices focused on memorization. These factors hindered the construction of meaningful learning and the development of scientific thinking in seventh-grade students. To address this problem, a didactic proposal was designed based on the pedagogical use of digital tools, integrating innovative methodologies and grounded in the principles of meaningful learning and universal design for learning. The research followed a mixed-methods approach, descriptive, non-experimental, and field-based, allowing for the combination of quantitative and qualitative techniques for the processing, analysis, and evaluation of the proposal. The results of the expert evaluation confirmed the pedagogical relevance, curricular coherence, scientific rigor, and feasibility of implementing the proposed didactic strategies. It was concluded that the implementation of these strategies promotes active student participation, the understanding of natural phenomena, and the development of meaningful learning through the pedagogical use of digital tools.

Introduction

Technology has significantly transformed contemporary educational processes, becoming a fundamental resource for pedagogical innovation and the improvement of the teaching and learning process. Currently, technological resources not only facilitate information management and communication but also promote the active construction of knowledge through interactive, collaborative, and contextualized experiences.

This study is based on learning theories that recognize the active role of the student and the construction of knowledge. Vygotsky (1979) proposed that learning occurs in a social context through interaction with others, highlighting the importance of cultural mediation and language as tools for cognitive development. In this sense, digital tools can be considered contemporary cultural mediators that expand the zone of proximal development by allowing students to learn with the support of technological tools and collaboration with their peers and teachers. Piaget & Inhelder (2008), for their part, maintained that learning is a constructive process in which the individual actively organizes and structures their knowledge through assimilation and accommodation. In the teaching of Natural Sciences, digital tools facilitate learning experiences that stimulate logical thinking and problem-solving, promoting the transition between stages of cognitive development through virtual manipulation and autonomous exploration of content. Ausubel (1983) argued that new knowledge is substantively integrated into the student's cognitive structure when it is related to prior knowledge and has personal meaning. Digital tools in the teaching and learning process of Natural Sciences act as facilitators of the connection between prior and new knowledge because they offer visual representations, simulations, and interactive experiences that stimulate the understanding and retention of scientific knowledge.

The use of technological resources for educational purposes has been extensively studied by authors such as Salinas & De-Benito (2020), who argue that the integration of information and communication technologies (ICTs) in education fosters student participation as the protagonist of their own learning, allowing them to develop cognitive, social, and digital skills in accordance with the demands of the knowledge society. Castro & Alanya (2024) conducted a study highlighting the potential of ICTs in interactive and dynamic learning, as well as the need to adapt the curriculum to current demands. They emphasized the urgency of developing digital skills and collaborative strategies to address the challenges of online education. According to these authors, this new scenario encourages teachers to rethink their methodologies and incorporate digital tools that enhance motivation, innovation, and the understanding of curricular content.

In the case of Natural Sciences, the use of technological resources acquires particular relevance, enabling the observation of natural phenomena, virtual experimentation, and the simulation of processes that are complex or inaccessible in the traditional classroom. Several studies highlight that technology allows for the visual and dynamic representation of scientific concepts, facilitating the understanding of abstract notions and promoting meaningful learning.

This is the case, for example, of Viñan & Montoya (2023), who conducted a study to analyze the influence of ICTs on the learning of Natural Sciences by sixth-grade students; concluding that the use of ICTs significantly improves the learning of Natural Sciences in this group of students. Furthermore, Coello (2023) analyzed how Google Classroom, an online educational platform, influences the learning of Natural Sciences in ninth-grade students. He conducted a quasi-experimental study that included a control group, allowing for a comparison of results between students who used Google Classroom and those who followed a traditional teaching approach.

The results revealed that the experimental group using Google Classroom obtained significantly higher grades compared to the control group that followed the traditional teaching method. The statistical analysis supported the hypothesis that the effective integration of digital tools in the teaching of Natural Sciences has a positive impact on the understanding of scientific concepts and on student motivation.

Alcívar & Bowen (2024), designed a methodological proposal using Educaplay for teaching Natural Sciences to fourth-grade students. The results demonstrated that Educaplay develops interactive activities that promote student participation, making learning more dynamic and engaging. This allowed them to conclude that the application of Educaplay had a positive effect on the teaching of Natural Sciences, given the significant difference in correct answers compared to those of a traditional explanation. This research corroborates the need to integrate technological tools into the teaching of Natural Sciences as an effective means to promote meaningful learning in seventh-grade students. The studies analyzed agree that the pedagogical use of ICT strengthens conceptual understanding, motivation, and active student participation. They also highlight that the incorporation of technology must be accompanied by adequate teacher training and intentional lesson planning capable of linking scientific content with practical experiences and real-world contexts.

The Ministerio de Educación del Ecuador (2023) has promoted policies aimed at strengthening teachers' technological skills and the pedagogical use of ICTs, recognizing their potential to improve educational quality and foster scientific literacy. However, in the Ecuadorian context, challenges persist that limit the integration of technological resources into teaching practice, related to infrastructure, teacher training, and equitable access. Furthermore, the effectiveness of these resources depends on their integration with appropriate teaching strategies that respond to the characteristics, interests, and contexts of the students.

At the Shungumarca Educational Unit in the General Morales parish of the Cañar canton, seventh-grade students have difficulty understanding fundamental scientific concepts and show little motivation toward learning this subject. Among the main causes of this situation is the limited use of the potential offered by digital tools in the teaching and learning process. Although the institution has certain resources and internet access, its pedagogical use is still in its infancy and is often limited to information searches or static presentations, without taking advantage of its didactic value for virtual experimentation, simulation of natural phenomena, or interactive learning. This is compounded by factors such as insufficient teacher training in the use of information and communication technologies, a lack of innovative methodological strategies, and the persistence of traditional models focused on memorization. The combination of these factors limits the development of scientific and critical thinking in seventh-grade students, hindering the development of meaningful learning. Therefore, the research problem of this study is: How to contribute to the development of meaningful learning in seventh-grade students in the subject of Natural Sciences at the Shungumarca Educational Unit, located in the General Morales parish of the Cañar canton?

To address this problem, the research objective is established as: To propose didactic strategies based on the pedagogical use of digital tools that promote the development of meaningful learning in seventh-grade students in the subject of Natural Sciences, at Shungumarca Educational Unit, in the Cañar canton.

Materials and Methods

The research follows a mixed-methods approach (qualitative-quantitative), which allows the authors to delve deeper into the problem identified at the Shungumarca Educational Unit in relation to the learning of seventh-grade students in the subject of Natural Sciences. The research is descriptive, non-experimental, and field-based, because it studies the scientific phenomenon in its natural environment, obtaining data directly from seventh-grade teachers and students about the learning process of Natural Sciences, without manipulating or controlling the variables.

This research employs a variety of scientific methods, ensuring the rigor and coherence of the investigative process. Among the theoretical methods used is analysis-synthesis, which allows the authors to thoroughly examine the learning process in Natural Sciences through the review, comparison, and systematization of existing theoretical frameworks. This facilitates the understanding of the relationships between the concepts, principles, and pedagogical approaches that underpin the teaching and learning process in this area of ​​knowledge, leading to the construction of a solid theoretical framework. Furthermore, the inductive-deductive method is applied during the diagnostic phase, allowing for the collection of information from concrete facts and experiences related to the use of digital tools in the teaching and learning process of Natural Sciences. To establish generalizations, general theoretical principles are used to interpret and explain the phenomenon under investigation.

At the empirical level, the following methods are used: observation, surveys, and interviews, which guarantee a direct approach to educational reality. Through observation, the authors can systematically identify classroom dynamics, the pedagogical strategies employed, and the level of student participation during classes. The interview facilitates obtaining qualitative information from the teachers' perspective, providing a deeper understanding of their practices, perceptions, and limitations in the use of digital tools. The survey, on the other hand, allows for obtaining quantifiable information about the experiences, attitudes, and difficulties faced by seventh-grade students in the subject. Furthermore, statistical mathematical methods are used for processing the quantitative information, interpreting, and tabulating the data obtained. To assess the relevance of the proposal, the expert judgment method is used.

The research was conducted at the Shungumarca Educational Unit, located in the General Morales parish of the Cañar canton, Cañar province, which belongs to Zone 6. It is a rural educational center offering in-person instruction in both morning and evening sessions. The study population consisted of the 61 seventh-grade students and the three teachers who teach Natural Sciences. Due to the authors' interest, a purposive sample of 31 students from section A was selected to analyze the research topic in depth, while the three teachers remained involved.

The methodological approach used in the research was developed in three stages: the first was the initial diagnostic phase; the second involved designing didactic strategies based on the pedagogical use of digital tools; and the third stage consisted of the application and evaluation of the proposed approach.

Stage 1: Initial Diagnosis.

During the diagnostic phase, various research techniques were used to gather information that would characterize the current state of seventh-grade students in relation to learning Natural Sciences at Shungumarca Educational Unit. The survey, administered to seventh-grade students, consisted of an eight-question closed-ended questionnaire. Interviews were conducted with the three teachers who teach the subject. Participant observation was also carried out using an observation guide to obtain qualitative information on the use of digital tools in the teaching and learning process of Natural Sciences.

 

Analysis and discussion of the results

The results of the first four questions reveal different perceptions among the students regarding their preferences and understanding of Natural Sciences (see Figure 1). In response to the first question, 42% of the students stated that they enjoyed learning the subject, while 32% indicated that they did not, and the remaining 26% only sometimes enjoyed learning about Natural Sciences. These data reveal a moderate level of motivation towards the subject, possibly influenced by the teaching methodology or the limited use of technological resources. In response to the second question, 39% of the students surveyed found the classes interesting and easy to understand, the same percentage (39%) perceived them as difficult, and 22% considered Natural Science classes only sometimes interesting and easy to understand. This suggests an urgent need to rethink the teaching strategies used in class, as more than half of the surveyed group does not find Natural Sciences sufficiently engaging or understandable.

Regarding the use of technological resources, the results are less encouraging; only 23% of the students indicated that the teacher frequently uses digital tools, while 42% responded that they never do, and 35% stated that technological tools are only sometimes used in the classroom. This trend can be explained by the students' responses to question two, which revealed a low level of understanding and motivation for the subject. In question four, 48% of the students acknowledged that the use of technological resources helps them better understand Natural Science topics, compared to 19% who felt it was not helpful. This indicates a positive assessment by the students regarding the use of digital tools in their learning; however, the data above confirm that their integration into Natural Science classes is still insufficient and requires more intentional lesson planning to generate meaningful learning.

The results of the last four questions reflect a contrast between the availability of technological resources and their pedagogical use, as shown in Figure 2. For example, in question 5, 61% of students reported having access to digital devices, while 23% indicated they did not, and 16% said they only had access to these resources occasionally. This demonstrates that most students have technological resources at home or in their surroundings.

In question 6, 68% believe that the school has sufficient technological resources, while 13% doubt their sufficiency. This availability does not guarantee the effective pedagogical use of these resources, and this is corroborated in question 7, where 52% of students stated that teachers do not teach them how to use digital tools to learn Natural Sciences, compared to 26% who said they do, and 23% who said they only do so sometimes.

This result reveals a training gap among teachers regarding the use of digital tools. In the final question, 68% of the students surveyed acknowledged that the use of digital tools makes classes more dynamic and motivating, while only 13% disagreed. In short, students value the impact of digital tools on their learning, but the data confirms that their integration into the teaching and learning process of Matter and Energy topics is still insufficient and requires more intentional lesson planning to generate meaningful learning.

These results indicate that technological resources cannot be viewed solely as technical instruments, but rather as pedagogical resources that, when properly integrated, enhance students' cognitive processes, critical thinking, and creativity. (Rey & Vergara (2025), urge educational institutions to utilize digital learning processes that foster students' critical thinking, implying a shift from traditional pedagogical approaches. In the case of teaching and learning Natural Sciences, digital tools enable the exploration of phenomena that, due to their complexity or inaccessibility, are difficult to address in physical environments. From the perspective of Espinoza (2023), digital resources in Natural Sciences encompass a wide range of tools, including simulators, interactive applications, educational videos, and online learning platforms.

The teaching of Natural Sciences in seventh grade is characterized by the need to cater to a group of students in full transition to formal thought, who demonstrate a natural curiosity about their environment and an interest in scientific phenomena, but who require active methodologies that promote their participation. In educational practice, it is observed that the teaching process, in many cases, focuses on the transmission of content and memorization, which limits the possibility of developing critical and scientific thinking in students. The lack of use of digital tools restricts the creation of more dynamic, interactive, and contextualized learning experiences. According to information obtained from interviewed teachers and observations made, the predominant strategies in the classroom are lectures, reproduction exercises, and basic experiments; although these allow for some learning, they are insufficient to foster meaningful learning. The absence of active methodologies such as gamification, cooperative and collaborative learning, or the use of digital tools reduces opportunities for students to actively construct knowledge.

The integration of digital tools into science education is limited and, in most cases, is reduced to the use of audiovisual resources and presentations. Although these tools help capture students' attention and facilitate the visual understanding of certain natural processes, their application lacks a structured pedagogical approach. According to teachers, the training they receive for the pedagogical use of technology is insufficient, preventing them from leveraging its potential to foster meaningful learning, experimentation, and the application of knowledge in virtual contexts.

Another difficulty teachers face when incorporating digital tools into matter and energy classes is the lack of adequate infrastructure and the insufficient time to plan innovative activities. Added to this is an implicit resistance to methodological change, stemming from the persistence of traditional teaching models. These conditions hinder the effective implementation of strategies that promote the use of digital tools and impede the development of scientific competencies in students. This information indicates that it is necessary to strengthen the processes of continuous teacher training oriented towards the didactic use of digital tools, prioritizing practical training contextualized to the national curriculum and fostering spaces for collaboration among teachers for the exchange of successful experiences, as well as promoting institutional policies that encourage educational innovation.

Stage 2: Design of teaching strategies based on the pedagogical use of technological resources in Natural Sciences.

Technological resources in education encompass both hardware and software, from physical equipment (computers, tablets, projectors) to virtual platforms, interactive applications, and digital learning environments (Madrigal et al., 2025). Their value lies in their ability to diversify teaching methods, promote active student participation, and generate more dynamic, contextualized, and meaningful learning experiences. Digital tools, as part of these resources, facilitate the acquisition, processing, and communication of information, becoming essential mediators of learning in the current educational context. They are specific applications or programs that enable the development of interactive, creative, and collaborative pedagogical activities. According to Romo et al. (2023), digital tools allow for the transformation of traditional learning environments into dynamic, participatory, and student-centered spaces through the integration of multimedia resources and active learning strategies. Examples of these applications include Kahoot, Genially, Quizizz, and Canva, which enhance knowledge construction.

These represent the operational component of technological resources, as they are the concrete instruments that teachers use to design more active and contextualized learning experiences. Their use in the teaching of Natural Sciences becomes an effective means of linking curricular content with the digital and scientific competencies demanded by today's society, provided it is based on a didactic plan. Teaching this area aims to promote students' understanding of physical, chemical, and biological phenomena and processes, as well as the development of critical thinking, inquiry skills, and attitudes of respect for the world around them.

The teaching strategies designed for seventh year of Basic General Education for Natural Sciences are aligned with the skills of the Ecuadorian curriculum and integrate digital tools, active methodologies and respond to principles of inclusion and accessibility, in accordance with the Universal Design for Learning (UDL) approach.

According to the results of this process, the proposed strategies comply with the required pedagogical, curricular, and scientific principles, respond to the characteristics of the students, the educational level, and the context, and effectively integrate digital tools. This ensures that their practical application will foster the development of meaningful learning, active participation, and the development of scientific, technological, and socio-emotional skills in seventh-grade students, contributing to the comprehensive education of students in Ecuadorian basic education.

Final decision: Their application will be approved with minor adjustments regarding the accessibility of the strategies in educational environments with technological limitations, such as rural contexts.

Conclusions

The research was based on theoretical foundations that highlight the importance of the pedagogical use of digital tools and active methodologies in the teaching of Natural Sciences, considering that these promote the construction of meaningful learning, critical thinking, and active student participation in their educational process. The diagnostic assessment revealed limited use of the potential of digital tools in the teaching and learning process of Natural Sciences, a scarcity of innovative strategies, and a tendency toward traditional teaching models. This limited scientific curiosity and the development of meaningful learning among seventh-grade students at the Shungumarca Educational Unit in the Cañar canton.

The proposed teaching strategies were evaluated by specialists, who confirmed that the proposal is consistent with pedagogical, curricular, and scientific principles.
