3.1. Sustainability and Environment on the Education System Regulations
Interest in sustainability and the environment has increased in recent years in line with the increase in references in the state regulations that have governed the Spanish education system (see
Table 2):
The Organic Law 1/1990 (Oct 3rd) on the General Organization of the Educational System (LOGSE) [
15], did not reference sustainability, but three allusions to environment—making them the first to refer to education for sustainable development in Spanish educational regulations. Later, in the Organic Law 2/2006 (May 3rd), on Education (LOE) [
16], there is a direct reference to sustainability, increasing the number of references to environment to five. The number of references to environment and sustainability has increased on the basis of the Organic Law of 8 December 2013 for the Improvement of Educational Quality [
17], which makes four explicit references to sustainability and maintains the five references to environment.
If we analyze, on the other hand, the specific content of these regulations, the LOGSE (1990) recognized, for the first time, that one of the principles of the education system was “training in respect for and defense of the environment”. This principle was consolidated by including, in the stages of Primary Education and Compulsory Secondary Education, the skills that students should acquire at the end of each of the stages. Article 13 specified the need to value “the conservation of nature and the environment”, while Article 19 extended this idea by recognizing the need to “critically assess social habits related to health, consumption and the environment”.
Afterwards, the LOE (2006) established that one of the principles that the education system should have is the acquisition of values that encourage respect for living beings and the environment, in particular the value of forest areas and sustainable development (Article 2).
This principle is reflected in the objectives of the different stages. For example, it is recognized that Compulsory Secondary Education must promote the critical evaluation of “social habits related to health, consumption, care of living beings and the environment, contributing to their conservation and improvement” (Article 23). The Pre-university Education, on its part, contemplates that this stage should contribute to “Knowing and valuing critically the contribution of science and technology in changing living conditions, as well as strengthening sensitivity and respect for the environment” (Article 33). Finally, Article 40, devoted to the objectives of professional training education, points out that it should help to “Know and prevent environmental risks”.
Finally, the LOMCE (2013) recognizes in its Preamble the need to implement a reform based on the European Union Strategy for intelligent, sustainable, and integrating growth. Specifically, five objectives were established for the 2020 Horizon in the areas of employment, innovation, social integration, education, and climate and energy, being the relationship between the last two the object of our study. In relation to education, the reduction in school dropouts was proposed, with no explicit goal in relation to climate and energy.
However, we must point out that one of the aims of education (Article 2, e) is recognized as being “training for peace, respect for human rights, community life, social cohesion, cooperation and solidarity among people, as well as the acquisition of values which promote respect for living beings and the environment, in particular the value of forest areas and sustainable development”.
This aim is made explicit in the regulations themselves in the objectives pursued by Compulsory Secondary Education, the Pre-University Education and Professional Training Education, with no reference to Pre-School and Primary Education.
Specifically, it is recognized as an objective (in Article 23, above mentioned) of Secondary Education to “critically assess social habits related to health, consumption, care of living beings and the environment, contributing to their conservation and improvement” (Article 23, k), highlighting the need to promote care of the environment.
3.2. Sustainability and Environment in Compulsory Education: A Stage Analysis
Analyzing in a specific way the regulations that govern the different stages that are the object of our study, the promotion of environmental education and sustainability is quite varied, being more present in Compulsory Secondary Education than in Primary Education.
On one hand, Royal Decree 126/2014 (Feb 28th) [
18], which establishes the basic curriculum of Primary Education, states in its preamble that this stage must incorporate curricular elements “related to sustainable development and the environment”.
Apart from this first allusion, we can find a total of six references to sustainability and ten to the environment within the framework of the different subjects (see
Table 3):
As can be seen, references to sustainability are limited to the areas of Natural Sciences and Social Sciences, while those related to the environment are also related to foreign language and social and civic values.
It is worth beginning by stating that the integration of these concepts in Foreign Languages is limited to the learning of high-frequency oral vocabulary, including the environment, climate, and natural surroundings as one of the areas of learning and, therefore, it is an approach that is not linked in itself to the promotion of the subjects that we are dealing with.
However, most of the explicit allusions to the phenomenon that concerns us are concentrated in the Social Sciences subject, and therefore focusing on the human influence on the environment and its environmental consequences. “Sustainable development” is stipulated as a content itself, being one of its evaluation criteria the explanation of the influence of human behavior on the natural environment, identifying the sustainable use of natural resources by proposing a set of measures needed for the sustainable development of humanity, specifying its positive effects. Likewise, a learning standard is envisaged in this same subject relating to the responsible use of natural resources and the proposal and adaptation of measures leading to the enhancement of environmental conditions. It can be derived from this analysis that this subject integrates issues of a theoretical nature, but also applied, providing a global integration of the subject.
On the other hand, we also find related contents in Natural Sciences, recognizing that “science is an indispensable instrument to understand the world around us and its changes, as well as to develop responsible attitudes on aspects related to living beings, resources and the environment”. Specifically, it is in the block of Matter and Energy where the identification of the benefits and risks of the use of energy for sustainable development is recognized as one of the learning standards, making a theoretical approach to the content without an explicit practical application.
Finally, within the subject of Social and Civic Values, is highlighted the need to reflect on the impact of science and technology on the protection and conservation of the environment. Specifically, the selection and contrast of information regarding threats to the environment and life derived from science and technology is recognized as a standard of learning, taking into account issues such as the uncontrolled exploitation of natural resources, habitat destruction, chemical and industrial pollution, acid rain, climate change, desertification, etc. This proposal therefore integrates a theoretical and practical treatment that includes reflection or research.
On the other hand, Preamble of the Royal Decree 1105/2014 (Dec 26th), establishes the basic curriculum of Compulsory Secondary Education and the Pre-university Education [
19]. It contemplates, as in the previous stage, that “the curricula of Compulsory Secondary Education and the pre-university education will incorporate curricular elements related to sustainable development and the environment”.
If we look at the inclusion of references in the stages regulated by these regulations, we can see that there is a sum of 221 (45 relating to sustainability and 178 to the environment), with more references in Compulsory Secondary Education. In this stage, there are 24 references to sustainability and 97 to the environment, while in Secondary Education there are 21 and 81, respectively, (see
Table 4):
Focusing the analysis on Compulsory Secondary Education, it is relevant to note that it is recognized as one of the objectives of the stage (article 11) to “critically assess social habits related to health, consumption, care of living beings and the environment, contributing to their conservation and improvement”.
It should be pointed out that there are various types of subjects and, therefore, not all of them take the same subjects during this stage, due to the training itineraries and the possibility of choosing specific subjects:
Core subjects: all students, during the first cycle of the stage (from 1st to 3rd year), take Physics and Chemistry, Geography and History, and First Foreign Language.
Core Itinerary Subjects: in the 4th year, students can choose either the Academic Education route (leading to the Pre-university Education Program) or the Applied Education route (leading to Professional Training Education). The following are part of the academic courses: Physics and Chemistry, Biology and Geology, and Economics, while in the applied course they are part of the Pre-university Education: Sciences Applied to Professional Activity and Technology.
Specific subjects: in each of the cycles, there are a series of subjects that students can choose to take, with the exception of Physical Education (which is taken in all the courses) and Religion or Ethical Values (one of which is also taken annually). The remaining subjects that are part of this group are Technology (first cycle), Scientific Culture (second cycle) and Plastic, Visual, and Audio-visual Education (first and second cycle).
The number of references we find in the different subjects is very diverse, with some of them contemplating allusions to both phenomena (sustainability and environment) and others where only the latter is mentioned. For example, Biology and Geology accounts for the greatest number of allusions (37.5% to sustainability and 23.2% to the environment), followed by Sciences Applied to Professional Activity (20.8 and 17.9%, respectively), Physics and Chemistry (12.5 and 11.6%) and Scientific Culture (4.2 and 10.5%), as can be seen in
Table 5:
The content analysis linked to this stage is presented on the basis of two criteria: the number of references and the presence of both concepts. In this way, the subjects where there are references to sustainability and the environment are first dealt with and ordered by the frequency of these references (following the structure of the table above).
The area of Biology and Geology accounts for 37.5% of references to sustainability and 22.7% to the environment. This is because, according to the regulations, this subject must contribute to students’ familiarity with nature and to the development of responsible attitudes towards sustainable development.
During the first, and third year of Compulsory Secondary Education, this subject deals with the importance of the conservation of the environment for all living beings, promoting the understanding and appreciation of preserving the environment because of its impact on health and of being responsible for the consequences of their decisions on the environment. Specifically, in Block 2, dedicated to the earth and the universe, we can see that three of its evaluation criteria and corresponding learning standards are linked to the responsible use and sustainable management of mineral resources, environmental pollution, and the proposal of solutions, and to the sustainable management of water. Likewise, in Block 3 (Ecosystems), we can find as content the actions that promote the conservation of the environment, associated with evaluation criteria and learning standards oriented towards the recognition of actions that promote their conservation. In this case, a theoretical approach can be observed, accompanied by applied actions aimed at reinforcing the aspects dealt with.
Also, in the subject of the 4th year, we find explicit references to the concepts that concern us in two of its blocks: The evolution of life (Block 2) and Ecology and the environment (Block 3). In them, the contents are established as “Human activity and the environment”, “Environmental consequences of human energy consumption”, and “Knowledge of simple techniques to know the degree of pollution and purification of the environment”. In them, we can find evaluation criteria and learning standards dedicated to evaluate the applications of technology in the environment, the recognition of the environmental factors that condition the development of living beings in a specific environment and the importance of its conservation, the sustainable management of resources or the importance of the use of renewable energies for the sustainable development of the planet. In this way, the integration of the topics has a predominantly theoretical orientation, leaving only a practical standard of learning focused on the defense of actions for the improvement of the environment.
Meanwhile, the specific subject of Sciences Applied to Professional Activity (4th year) accounts for 20.8% of references to Sustainability and 17.5% of references to the environment. The objective of this course is to learn about science, its applications to professional activity and the environmental impact of obtaining different necessary products for industry and consideration of the sustainable use and management of resources. Thus, in Block 2, dedicated to the applications of science in the conservation of the environment, the different types of environmental pollutants are studied, their origins and negative effects, as well as the treatment to reduce their effects and eliminate the waste generated. It also includes research activities for solutions to the environmental problem. Concretely, Pollution: concept and types, as well as soil, water, air and nuclear pollution are considered as contents, introducing waste treatment, basic and experimental notions of environmental chemistry and sustainable development. All these contents are materialized in evaluation criteria and learning standards of a conceptual nature (what is pollution, which are the most representative types, what environmental effects do they produce in the soil, air, water, or what is it, and what does sustainable development imply), but also of a procedural nature (apply resource control measures or propose sustainability strategies for the center) and attitudinal (argue advantages and disadvantages of recycling and reusing resources or participate in awareness campaigns for the conservation of the environment), providing a global character to the integration of our study topics.
In the area of Physics and Chemistry, for its part, we find 12.5% of references to “sustainability” and 11.3% of references to “environment”. This area also deals with the industrial and social implications related to health and the environment, as well as environmental chemistry, with the aim of students being able to critically assess the social implications of these scientific advances, in order to guide society towards a sustainable future. In 2nd and 3rd year of Compulsory Secondary Education, where the subject is core for all students, it is introduced as an evaluation criterion “to know and respect the safety and waste disposal regulations for the protection of the environment”. Likewise, and linked to the content of “Chemistry in society and the environment”, evaluation criteria and learning standards are considered, assessing the importance of the chemical industry and its influence on the environment (greenhouse effect and other global problems). It also establishes, as a standard, the proposal of measures and attitudes to mitigate environmental problems. Similar evaluation criteria and learning standards are established in Block 5, although they are linked to energy. In this way, the role of different types of energy in life is addressed, comparing their environmental impact and recognizing the importance of saving them for sustainable development.
For its part, in the 4th year, where the subject is the core of the Academic Sciences itinerary, some of these issues are dealt with in greater depth. Specifically, in Block 3, dedicated to changes, the importance of chemical reactions and their environmental impact, an issue that is also included as a content (Social and environmental consequences of chemical combustion reactions) and as an evaluation criterion (Analyzing the influence of combustion reactions at a social, industrial and environmental level) in Block 4 “Energy transformations and spontaneity of chemical reactions”, is established as an evaluation criterion. Finally, in Block 5, the description and assessment of the role of carbon chemistry in our lives and the need to adopt sustainable environmental measures are considered as evaluation criteria and learning standards. Under this perspective, it could be concluded that, although it offers a mostly theoretical view of sustainability and the environment, it also incorporates evaluation criteria and learning results of an applied nature.
For the specific subject of Scientific Culture (4.2% of the references to sustainability and 10.3% to the environment), we find an allusion to sustainability and 10 references to the environment, all of them as evaluation criteria and learning standards and practically all of them linked to Block 3 (Technological advances and their environmental impact). In it, we can find issues such as the identification of the main environmental problems, their causes and consequences, the knowledge and analysis of the main international agreements and protocols on the protection of the environment, the search for solutions, the evaluation of the consequences of the over-exploitation of resources and the need to experiment with new ways, as well as the argument on the need for a sustainable management of resources. In this way, our study concepts are approached in a global way, giving a theoretical and practical coverage to the contents.
In Geography and History, a general core subject for all students in all four courses, 12.5% of the references are related to sustainability and 6.2% to the environment. In the distribution of the 1st to 3rd year, the references are linked to Blocks 1 (the physical environment), 2 (human space), and 9 (Technological Revolution and Globalization). In the first of these, content on the physical environment is established, including content relating to the natural environment and environmental problems, establishing as an evaluation criterion the knowledge, description and assessment of human action on the environment and as a learning standard the search for digital references relating to environmental problems. On the other hand, the Block 2 establishes sustainable development as a content, as well as the three sectors, the environmental impact, and the use of resources. Linked to these, the evaluation criteria focus on knowing and analyzing the environmental problems and challenges and the possible ways of facing them, as well as understanding the idea of “sustainable development” and its implications. Finally, in Block 9 it is highlighted, as an evaluation criterion, to recognize the impact that the technological revolution and globalization have on environmental issues. The proposed approach is in practice entirely theoretical, and there are few references that would include an applied treatment.
The subject of Economics is contemplated as the core subject for those students who are studying the academic courses in 4th year. Its link with the subject that concerns us is related to the approach of the environment as a key context for economic development. Specifically, in Block 2 (Economics and Business), it is established as a standard of learning to identify different types of companies in an environment, as well as the social and environmental effects that are derived. Additionally, in Block 6, from the approach of the international Economy, a content related to “The economic consideration of the environment: sustainability” is contemplated, which is materialized in an evaluation criteria associated with evaluating the impact of economic globalization and international trade on the quality of life of people and the environment, as well as the consideration of environmental problems in relation to the international economic impact and the analysis of possibilities for sustainable development. It could be said that the treatment of the environment responds to a predominant theoretical approach, leaving the applied approach in second place.
The two topics are also dealt with in Technology which, as we have already mentioned, is a specific subject in the first cycle (1st to 3rd year) and a core subject in Applied Teaching in the 4th year. This subject is oriented, among other issues, to encourage students to acquire “technological autonomy behavior with environmental and economic criteria”, showing that these are contents with an eminently applied orientation. In the first three years, we can find an evaluation criterion linked to our study, within Block 1 (Process of solving technological problems). Specifically, it establishes the need to “carry out the technical operations stipulated in a work plan using material and organizational resources with criteria of economy, safety, and respect for the environment”. In the fourth course, the content is “Acquisition of habits that promote sustainable development” (Block 6. Technology and society), although no evaluation criteria or learning standards are specified that would allow this to be materialized in a specific way.
On the other hand, and focusing on subjects where only the environment is mentioned, the highest number of references is in First Foreign Language (9.3%). However, as was the case in Primary Education, the allusions to the concepts which are the object of study in our work are associated with the learning of commonly used vocabulary, where the environment, climate, and natural surroundings are included again.
In the subject of Ethical Values, despite being a specific subject throughout the stage, the references are accounts for in the fourth year. In it, we can find three learning standards linked to the environment and framed in Block 3 (Critical reflection), Block 5 (Ethical values, law, the UDHR (Universal Declaration of Human Rights) and other international treaties on human rights) and Block 6 (Ethical values and their relationship with science and technology). In the first of these, the identification of new fields where ethics is applied is established as a standard, the environment being one of them. Meanwhile, Block 5 contemplates the elaboration of an audio-visual presentation on some of the threats to peace and security, recognizing environmental disasters as one of these problems. Finally, in Block 6 the need to take into account ethical and environmental criteria to consider the viability of scientific and technological projects is pointed out. The treatment of the environment is, in this case, mixed, proposing aspects of a theoretical and practical nature.
In the case of Physical Education, the two references are also accounts for in the fourth year, where the recognition of the environmental impact of physical and sporting activities and the reflection on their repercussion on the environment are recognized as evaluation criteria. From this, three learning standards are derived, focusing on comparing the effects of different activities on the environment, on relating physical activities in nature to health and on demonstrating habits and attitudes of conservation and protection of the environment, thus providing a theoretical and practical approach to our object of study.
There are also two references in the specific subject of Initiation to Entrepreneurial and Business Activity, although in this case in the first cycle (1st to 3rd year). This is an evaluation criterion and its corresponding learning standard in Block 2 (business project), where the need to consider the importance of environmental impact and ensuring the conservation of the environment in the process of starting up a company is highlighted. Although the purpose of these elements is applied, the approach itself is theoretical.
Finally, the subject of Plastic, Visual, and Audio-visual Education establishes, for the first cycle, a standard of learning linked to the use of recycled materials to be responsible with the environment, having an applied character.
Overall, the treatment of these two topics is mainly theoretical and not all subjects deal with them in a practical way, as can be seen in the following summary
Table 6. (Please note that from the subject “First Foreign Language” to the end of the table, the subjects only refer to the environment and not to sustainability).
