Ensuring sustainability requires a paradigm shift in conceptualization, thinking, research and Science education, particularly concerning the science-technology-environment-society (STES) interfaces. Consequently, STES literacy requires the development of students’ capabilities via higher-order cognitive skills (HOCS)-promoting teaching, assessment and learning strategies. Striving for sustainability and the consequent paradigms shift, from unlimited growth to sustainable development, makes the corresponding paradigms shift in science, environmental and technology engineering education, from algorithmic teaching to HOCS learning, to become unavoidable. The identified paradigms shift refect the ever-increasing social pressure towards more accountable, socially- and environmentally-responsible sustainable action. Concomitantly, this pressure constitutes the driving force for STES education for sustainability. This requires HOCS for responsibly dealing with multi-dimensional, socio-economical-technological-environmental systems. Our research findings and educational practice suggest, that, although the road to STES literacy for sustainability is rocky, it is educationally feasible and, therefore, attainable.
La garantía de la sustentabilidad requiere un cambio de paradigma en la conceptualización, pensamiento, investigación de la educación científica, de forma particular lo que se refere a las fronteras de ciencia-tecnología-ambiente-sociedad (CTAS, en inglés STES). Consecuentemente, la alfabetización CTAS requiere que los estudiantes desarrollen capacidades cognitivas de alto orden (HOCS en inglés) gracias a una enseñanza, evaluación y aprendizaje que las promueva. Esforzarse hacia la sustentabilidad hace que el paradigma cambie del crecimiento no limitado al desarrollo sustentable y hace que los paradigmas correspondientes en educación en ciencia, ambiental e ingeniería se desplacen inevitablemente de la enseñanza algorítmica al aprendizaje de habilidades cognitivas de alto orden. El cambio de paradigma es un reflejo de la presión social hacia una acción sustentable más social y ambientalmente responsable. Con-comitantemente, esta presión constituye la fuerza directora de la educación CTAS para la sustentabilidad. Ello requiere el aprendizaje de habilidades cognitivas de alto orden para vérselas con sistemas multidimensionales, de carácter socio-económico-tecnológico. Nuestros hallazgos de investigación y nuestra práctica educativa nos sugieren que, aunque el camino hacia la alfabetización CTAS es rocoso, resulta factible y, por lo tanto, alcanzable.
All sciences, particularly the environmental sciences, engineering and technology, are emerging as new multidimensional, cross-, inter- and transdisciplinary disciplines (Mihelcic, et al., 2003). They draw on all the basic sciences to explain the workings of the complex and dynamic ever changing earth and people-generated systems as a result of natural causes and anthropogenic impact (Glaze, 2002). Thus, the sciences, technology and engineering are undergoing a process of distancing themselves from specialized, compartmentalized, sub-disciplinary, un-dimensional enterprises focusing, instead, upon multidimensional, cross-boundary endeavors in the context of the science-technology-environment-society (STES) interfaces (Zoller, 2000ab, 2001; Gibbons et al., 2001). This process poses new challenges with respect to science, technology, engineering and the related STES literacies, as well as to organizations, societies, economies and (what goes without saying) politics. Inevitably, the consequenting paradigms shift in science —Chemistry, biology, physics, geography,… — STES-, STEM-, engineering-, environmental Education follow suit. From the perspective of sustainability, any relevant generated or acquired knowledge that is put into action in the STES context, should be guided by the idea[l]s of social responsibility (Zoller, 2012). Although sustainability is associated with a plethora of different meanings dependent on the specific STES context (Marshal & Toffel, 2005; Zoller, 2012), it ultimately requires that all involved parties operate within an open-ended, ideas-oriented culture (Negroponte, 2003), characterized by an ongoing inquiry (Laws et al., 2004). This, in turn, requires a corresponding new type of STES education targeted, purposely, to an agreed upon STES oriented literacy (Zoller, 2012).
The objective of this STES literacy for sustainability pedagogy, is to promote, in science, technology and environmental education, the development/enhancement of evaluative critical system thinking, decision making, problem solving and transfer (Barak et al., 2007; Ben-Zvi, Assaraf & Orion, 2005; Kurtam, 2013; Levy Nahum et al., 2010; Zoller, 1993, 1999, 2001, 2005, 2012; Zoller & Levy Nahum, 2012). Such learning objectives are, therefore, distinct from traditional basic learning, in which the emphasis is on knowledge gain rather than the development of the students’ transferable Higher-order cognitive skills (HOCS) capabilities (Zoller, 2012).
Our ‘global village-”free market”, people-made world’ requires a new type of flexible, contextually relevant, adaptive knowledge, that permits one to cope with the complexity and fragility of multidimensional global socio-economic-technological-environmental systems (Gibbons et al., 1994; Zoller, 1993). This need has served as an impetus for the emergence of both inter- and transdisciplinarity in environmental, natural/physical science research and in science, technology chemistry and STES education (Gibbons et al., 2001; Scholz, 2000; Thompson et al., 2001; Zoller, 2001, 2012; Zoller & Scholz, 2004), as well as for adequate strategies of technology assessment and sustainable action (Laws et al., 2004).
There is an ever-increasing gap between the reality of the 21st society, which is based on science, technology, economy, and advanced, sophisticated networked systems and capabilities and the response of the diverse, multi-sectorial educational systems, worldwide, to this reality. The latter are perceived by students, teachers, parents, society, economical, political and ... educational systems, as an instructional framework, the objective of which is to advance pupils/students up the classes’ ladder, based on their high scored passing of disciplinary, mainly algorithmic, knowledge-centered exams and/or “standardized” tests. Thus, pupils’/students’ learning is assessed and ranked according to their “grade achievement” and/or scores on related examinations as the exclusive criteria.
Given the current striving for sustainability and the corresponding paradigms shift in science, technology, R&D, environment perception, economy and policies; e.g., from unlimited growth-to-sustainable development, correction-to-prevention and passive, unlimited consumption of “goods”, culture and education — to active participation and involvement, primarily in STES, economy-policy (s-t-e-s-e-p) contexts, the corresponding paradigms shift, at all levels of education is unavoidable (Zoller, 1990, 1993, 1999, 2000a, 2011a). This requires a shift in conceptualization, thinking, research and practice in science/stem (Science, Technology, Engineering, Mathematics) education, particularly in the context of the STESEP interfaces, HOCS-promot-ing teaching, assessment and learning strategies (Zoller, 2000b, 2001, 2005, 2011b, 2012; Zoller & Scholz, 2004). This means a shift, in the diverse multi-sectorial and cultural global societies, from the currently dominating lower-order cognitive skills (LOCS) algorithmic teaching to know, to HOCS-promoting learning to think, for transfer (Zoller, 1990, 1993, 1999, 2000a,b).
Consistent with, and building upon, these visionary trends, the development of HOCS has been persistently invoked, purposing at the substitution of the conventional algorithmic teaching of science and technology (Zoller, 1999, 2001; Zoller & Pushkin, 2007; Zoller & Tsaparlis, 1997). Thus, the “battle cry” for sustainable development, worldwide, turned the latter into a major driving force in the rethinking and redesigning processes of STES-oriented science, technology, environmental education and environmental engineering courses, teaching strategies, assessment methodologies, learning styles and programs (Zoller, 2012; Zoller & Levy Nahum, 2012; Zoller & Scholz, 2004).
This means that the “translation” of science and technology to socially- and technologically- responsible action is contingent on the “hocs capability” of those involved and, in turn, should be shaped by responsive and relevant applied science education (Zoller, 1993, 1999, 2001; Zoller & Scholz, 2004).
Science and technology are useful in establishing what we can do, as well as in providing us with the ability to generate new options. However, neither singly nor in combination can they tell us what we should do. What ‘should be done’ requires the application of evaluative thinking and value judgment by socially responsible, reflective, and active participants, in relevant societal discourses (Zoller, 1999, 2001; Glaze, 2002; Schnoor, 2003). Therefore, the preparation of students for reasoned, intelligent, defensible, and responsible active participation in the mutual learning occurring amongst all parties involved in the democratic decision-making process, which is based on their HOCS thinking capability — an over-arching goal of sound education at all levels (Zoller, 1993, 1999, 2001, 2005, 2012).
In the context of STES literacy for sustainability, this would require (a) identification/categorization of the contemporary paradigms shift in STES-related science and technology research and education for sustainability; (b) integration of the ‘environment’ into science and technology education, by making it a core pillar of the STES approach (Yager, 1993; Zoller 2005). By doing so, the STES conceptual framework (Zoller, 1993, 1999, 2001, 2012) will become better geared for perpetuating sustainability in the STES context; and (c) promotion of a shift from ‘increasing knowledge capacity’ per se, to ‘enhancing thinking capability’ via in accord educational reform. This should be the basis for sustainability-oriented action in the STES-interfaces context (Zoller & Levy Nahum, 2012; Zoller, 2012).
Undoubtedly, the promotion of STES-focused education for sustainability in science education, at all levels, raises the issue of education versus indoctrination. In this context, science teachers’ job is not to tell the students what to think, but rather to develop their own thinking (Qablan et al., 2011). Significantly, in a research related to the education-indoctrination issue, conducted in BC Canada, it was found that the students’ beliefs and views post an STS curriculum, were different from those of their teachers, meaning education not indoctrination (Zoller et al., 1991a). The need for “stes teachers” who strive to understand what science means to students in their world/context”, is apparent (Kamen, 2011).
The STES related conceptual modelOur conceptual framework is presented in Figure 1. The main domains of STES and their (inter-) relationships form the core of the framework into which the related multidimensional educational domain is inserted. Other pertinent domains (not shown for simplicity) are operating within this framework.
The science-technology-environment-society (STES) framework for research and education for sustainability (Zoller, 2004a,b).
Figure 1 represents a simplified, qualitative systemic conceptualization of the so far dealt-with,- the interfacing four STES components. It conveys the integration of the environment as a core pillar in the science-technology-society (STS) approach (Yager, 1993) in science education and expanding it into STES-related educational frameworks, which are indispensable in the promotion of sustainability (Zoller, 1993, 1999, 2001; Robért & Anderson, 2002). Yet, the relative importance of the components in different contexts should, a priori, be considered as differing quantitatively and qualitatively, what is to be expected in sustainability-oriented research and education in the STES context.
Given the current striving for sustainability and the consequent paradigms shift, such as from unlimited growth to sustainable development, correction to prevention and from options selections to options generation, the corresponding paradigms shift in science and technology education, such as from algorithmic teaching to HOCS promoting learning, is unavoidable.
Such a shift from the traditional LOCS science teaching to ‘hocs learning’, is to be encouraged by science educators, national education policy makers, curriculum developers, teachers, STES/STEM educators and the public at large. The above refects the worldwide ever-increasing social pressure towards more accountable socially, environmentally, economically and politically responsible science, environmental and engineering education, essential for ensuring sustainable development (Zoller, 1993, 1999, 2000a, 2001, 2011b). Furthermore, science/STEM/STES educators, researchers, economists, cognitive psychologists and sociologists consider HOCS (Figure 2) to be important domains for students’ learning, for ensuring their capability to exercise a responsible citizenry in the context of Literacy for sustainable development (Table 1) (Zoller & Scholz, 2004).

HOCS are conceptualized as a non-algorithmic complex multi-component conceptual framework of reflective, critical, system and evaluative thinking, focusing on deciding what to believe and do, or not to do, in confronting (with) an issue or a problem to be solved, to be followed by a responsible action, accordingly (Zoller, 1990). Thus, e.g., the HOCS, critical thinking (CT), question asking (QA), decision making (dm) and problem solving (PS), constitute major components in the HOCS conceptual model (Figure 2) (Zoller & Levy Nahum, 2012;Zoller, 2012). This model refers to the interrelated generic- non content, but contextually bound cognitive capabilities there contained. Thus, the development of the learners’ HOCS is being the leading goal embedded in this conceptual model.
Table 1 summarizes the essence of the paradigms shift directions in environmental/stes research and education for sustainability within the framework conceptualized in Figure 1.
It is based on (a) previous disciplinary and interdisciplinary fundamental, theoretical and applied empirical research (Zoller & Levy Nahum, 2012; Zoller, 2012); (b) developed methodologies relevant to these various forms of research (e.g., Scholz & Tietje, 2002; (c) environmental- and STES-related research in science and chemical education (e.g., Zoller, 1993, 1999, 2001; Zoller & Pushkin, 2007; Zoller, 2012; Leou et al., 2006); (d) outcomes and conclusions of national and international conferences, symposia and workshops concerning environmental issues, problems, education, and policy (Zoller, 2004a); and (e) the development and implementation of large-scale interdisciplinary, STES-type curriculum projects (see e.g., Levy Nahum et al., 2010, Tal et al., 2001; Zoller & Rochell, 1991b; Zoller & Scholz, 2004).
The above identified paradigms shift (Table 1) refects the worldwide phenomenon of ever-increasing social pressure towards more accountable, socially- and environmentally-responsible sustainable development. Concomitantly, this pressure constitutes a driving force for, and a consequence of, the paradigms shift in the STES education for sustainability context. Understandably, all of the above requires new types of flexible, contextually-bound relevant, adaptive knowledge and, even more so, HOCS capabilities of critical evaluative system thinking, decision making and creative thinking for problem solving — for effectively and responsibly dealing/coping with the complexity and fragility of multi-dimensional economical, technological, environmental social and political systems [STESEP]. This implies the importance of consonant interdisciplinary methodologies, strategies, assessment and sustainable action and, in accord, “HOCS learning” in STES-oriented science and technology/STES/STEM education. In conceptualizing the essence of the current reform in science/technology education, worldwide, as a purposed effort to develop all students’ STES literacy, the implementation of appropriate research/evidence-based, HOCS-promoting teaching, assessment and learning strategies is proposed as the educational methodology of choice for effective science and technology teaching and learning, targeting at STES literacy for sustainability (Zoller, 2012).
Selected research-based illustrative ‘exemplaries’ of “how to do it”, i.e., promoting/developing of critical thinking, decision making and problem solving (in contrast to ‘exercise’ solving), in different contexts, at different levels, follow.
Purposely teaching for advancing students’ HOCSThe case of critical thinkingThis longitudinal case study (Barak, Ben-Chaim & Zoller, 2007), aimed at examining whether purposely teaching aimed at the promotion of HOCS, enhances science students’ critical thinking (CT), conceptualized by us as — results-oriented rational, logical and reflective evaluative thinking, in terms of what to accept (or reject) and what to believe in, followed by a decision what to do (or not to do); then, to act accordingly and, concurrently, taking responsibility of both — the decisions made and their consequences (Zoller, 1993, 1999). Within a pre-, post-, and post-post experimental design, high school students were divided into three research groups. The experimental group (N = 57) consisted of science students who were exposed to HOCS-promoting teaching. Two other groups, science (N = 41) and non-science majors (N = 79), were traditionally taught, thus constituted the control. By using critical thinking assessment instruments (Facione, 1990; Facione & Facione, 1992), we have found that the experimental group showed a statistically significant improvement on critical thinking skills components and disposition towards CT subscales, such as: truth-seeking, open-mindedness, self-confidence, and maturity, compared to the control groups. Our findings suggest, that if teachers purposely and persistently practice HOCS-promoting teaching’ e.g., dealing in class with real-world problems, encouraging open-ended class discussions, and fostering inquiry-oriented experiments, there is a good chance for a consequent development of CT capabilities.
HOCS-promoting assessment1The HOCS Evaluation Questionnaire (HEQ) (Zoller & Scholz, 2004; Levy Nahum et al., 2010)Assessing Question Asking:
- 1.1
Read the following paragraph. Formulate three questions that you would like to, or think, are important to ask concerning the subjects dealt with in the paragraph.
“Resources and energy: What are the future options and alternatives?
Almost every aspect of the Western world is based on the consumption of energy and products derived from the finite crude oil and natural gas resources. There are sufficient reserves of coal that could lead to the production of enough synthetic fuel and gas for the present time. However, energy alternatives (e.g., solar, wind, tide, and waves) should be developed to satisfy the need for the production of electricity. This would involve the substitution of diminishing resources by available non-finite resources. Nuclear energy is another possibility. Future alternatives concerning resource exploitation and energy supply require an in-depth analysis and intelligent decision... and the sooner the better.”
- 1.2
Assessing decision making:
- 1.
In your estimation, is the subject dealt with in the paragraph relevant to you? Explain your answer.
- 2.
Can you, based on the given paragraph (and the information it provides), decide on the desirable alternatives of energy supply in your country? Explain your answer.
- 3.
In case you think that you need more information in order to decide intelligently on the desirable alternative, formulate two questions that you would ask for answers before making the decision.
- 4.
Formulate two criteria that guides you (or will guide you) in your decision concerning the most desirable alternative.
- 5.
Briefly explain the pros and cons of the alternative(s) that you have chosen with regard to future implications. Compare your alternative(s) with any other alternatives that you did not choose.
- 6.
In your estimation, are (1) societal and/or (2) values and/or (3) political (distinguished from the scientific-technological-environmental considerations) involved in your decision/choice of the desirable alternative? Relate to 1, 2 & 3 in your answer and explain!
- 1.
Our main research-based conclusion is related to the promotion/development of question asking (QA) and decision making (DM) HOCS in the STES context is, that both require a longitudinal, persistent HOCS-oriented “STES”-(oriented) teaching education, the latter longer than the former (Leou et al., 2006; Levi Nahum et al., 2010).
Groundwater pollution by chromium (Cr), the origin of which is industrial disposal, constitutes a real health risk to the people who are using this water. The chromium-containing anions are CrO42–, mostly found in neutral water, and HCrO4, mostly found in more acidic water. Both are water-soluble. Usually, Cr concentrations in groundwater are less than 50 mg/L. However, in concentrations higher than 500 mg/L the dominant ion is Cr2O72–. In basic water Cr(OH)3 is mainly found. It is less water-soluble compared with the previous three and, apparently, less problematic than the other three with respect to its toxicity.
- 2.1
Try to hypothesize a possible reason for the differences in risk to the public between the chromium in Cr(OH)3 compared with that in the first three anionic species. [Question level: HOCS]
- 2.2
Suggest a simple experimental lab method with which you may determine the concentration of chromium in basic groundwater samples. Briefly explain how you would do that. [Question level: HOCS]
- 2.3
What, in your opinion, will be the effect of acid rain on the relative abundance of the ions CrO42–, HCrO4, Cr2O72– and Cr(OH)3 in chromium-contaminated ground water? Explain. [Question level: HOCS]
- 2.4
In your opinion, what will be the effects of a particularly rainy year on the chromium toxicity risk in drinking chromium-contaminated groundwater? Explain your answer. [Question level: LOCS]
- 2.5
In your opinion, are the concepts oxidation-valence, chemical bond, acidity, basicity, and electronegativity relevant and do they have a connection to your previous answers (2.1–2.4)? Explain. [Question level: HOCS]
This research focused on ‘problems’ that require HOCS for their solution, in contrast to ‘exercises’ that require just the application of algorithms and/or lower-order cognitive skills (LOCS), [to end up with only one “correct” answer]. We have studied science majors freshmen’s (N = 47) pre-post problem solving capabilities within ‘traditional’ college chemistry teaching which occasionally integrated environment-related, interdisciplinary problems. Our findings indicated, that although most students felt that it is within their capability to solve HOCS-level questions (problems!), ‘traditional’ chemistry teaching does not contribute much to the enhancement of their problem solving capability. However, students who performed well on the HOCS-type questions were found to: (a) successfully made connections between chemistry-related concepts and STES-oriented issues; (b) expressed their ideas using multiple representations: textually, qualitatively and quantitatively; (c) presented systemic reasoning, where applicable; and (d) evaluated and presented several alternative resolutions. These findings imply that a LOCS-to-HOCS shift from exercise, -to- problem solving capability, in science chemistry education, would require a shift from algorithmic-to HOCS-promoting teaching and assessment.
For an example of a mixed HOCS/LOCS chemistry exam questions for university freshmen see Box 1.
Summary, Conclusions and Implications‘HOCS-learning’ targeted at the development and enhancement of STES literacy for sustainability requires, neither the coverage of more advanced, domain-specific material, nor “increasing” students’ repertoire of disciplinary-bound algorithms. Rather, education for sustainability should take, among others, the following practice:
- 1.
“Translating” the new goals, agreed upon by all parties involved – stakeholders, policy makers and, mainly, STES, Science, Environmental and stem educators into effective systemic sustainability-oriented educational programs, curricula, courses, teaching, learning and assessment strategies (Zoller, 1993, 1999, 2001, 2004, 2011a, 2011b, 2012; Zoller & Scholz, 2004).
- 2.
Ensuring that such system- and sustainability-oriented educational courses and curricula become an integral part of the curricula of formal science, technology and engineering education, which will ensure their recognized (respectable) status, in science and chemical education.
- 3.
Developing and implementing HOCS-promoting assessment strategies as alternatives to the currently dominant (LOCS-oriented) assessment practice in traditional, disciplinary science, technology, the environmental education (Zoller, 1993, 1994, 1999, 2012; Zoller & Scholz, 2004).
The challenge of STES literacy for sustainability will require:
- 1.
The restructuring of education at all levels (including teacher professional development programs) towards this new type of learning, for all students, via the implementation of effective research-based HOCS-promot-ing teaching, assessment and learning strategies (Zoller, 1993, 1999; 2011b; Zoller & Levi Nahum, 2011).
- 2.
The teaching of how to systemically deal with complex, large systems using the case study methodology (e.g., large scale case studies (Scholz & Tietje, 2002), vis-à-vis ensuring the students’ Learning conceptalisation of fundamental trasdisciplinary concepts (Levi Nahum et al., 2010; Zoller & Levy Nahum, 2012).
- 3.
Extending interdisciplinary studies, research and “sites” teaching, in such a way, so that both students and relevant community “stakeholders” will become capable STES-literate active participants.
- 4.
Developing and promoting effective, easily accessible communication and interaction among participants of studies in the STES domains. This is necessary for building a new type of culture that enables a collaborative societal process of sustainability assurance, thinking-based learning.
Our accompanying longitudinal research application of this educational practice suggest that, although the road to STES literacy for sustainability is rocky, it is nevertheless, educationally feasible.
