This study’s goal was to analyze various teaching approaches within the context of natural science lessons, especially in biology. The main focus of the paper lies on the effectiveness of different teaching methods in promoting systems thinking in the field of Education for Sustainable Development. The following methods were incorporated into the study: special lessons designed to promote systems thinking, a computer‐simulated scenario on the topic “ecosystem forest,” and a combination of both special lessons and the computer simulation. These groups were then compared to a control group. A questionnaire was used to assess systems thinking skills of 424 sixth‐grade students of secondary schools in Germany. The assessment differentiated between a conceptual understanding (measured as achievement score) and a reflexive justification (measured as justification score) of systems thinking. The following control variables were used: logical thinking, grades in school, memory span, and motivational goal orientation. Based on the pretest–posttest control group design, only those students who received both special instruction and worked with the computer simulation showed a significant increase in their achievement scores. The justification score increased in the computer simulation condition as well as in the combination of computer simulation and lesson condition. The possibilities and limits of promoting various forms of systems thinking by using realistic computer simulations are discussed.

The importance of education, and ESD in particular, for achieving sustainable development is highlighted in the formulation of the Sustainable Development Goals (SDGs). Since the Brundtland Report (1987) and the Agenda 21 conference in Rio in 1992, many measures and programs have been launched. However, no widely accepted and validated assessment instruments are currently available to examine the output levels of ESD on the student side as a means to contribute to monitoring the effects of ESD initiatives. Furthermore, connections to the results of empirical educational research are often lacking. Indeed, operationalization is necessary in order to evaluate actions of fostering ESD. Taking concepts of empirical educational and other relevant research findings (for example, psychology for sustainability) into account, this study develops a reliable and valid approach to measuring sustainability competencies. In this paper, novel data of a first school assessment is presented. One thousand six hundred and twenty-two students (aged from 9 to 16) participated in the survey. The paper-pencil questionnaire covers general (socio-demographic) as well as cognitive, affective, behavioral, application- and curriculum-orientated aspects of sustainability competencies. The evidence for the validity and reliability of the instrument indicates that the presented assessment tool constitutes a suitable instrument by which to measure sustainability competencies in secondary schools. The gathered insights show a path towards the operationalization of sustainability competencies to clarify the needs and achievements of ESD implementation in schools.

After the end of the first Global Action Programme on Education for Sustainable Development, coinciding with ongoing international evaluation processes, questions about the implementation of the Education for Sustainable Development programs and assessments continue to be raised. The present study examined Education for Sustainable Development implementation at the local (teachers’) level, assessing what teachers think and know about Education for Sustainable Development and how they implement it in secondary school classes in Baden-Wuerttemberg, Germany. By providing novel data from a teacher survey in 2019, this study revealed that Education for Sustainable Development in some aspects still lacks concrete structural implementation in educational contexts. Using a longitudinal approach, we additionally compared data from an earlier representative assessment in 2007 to the data from 2019. In reference to the preceding evaluation report, the present study showed, for example, that teachers’ attitudes towards Sustainable Development Goals were significantly higher in 2019 compared to 2007. This study provides clarification of the needs and achievements of the Education for Sustainable Development implementation process. In sum, our analysis found that from the teachers’ perspective, more abstract policies are not needed, but instead teachers ask for very concrete support that is close to teaching and the schools’ objectives. The results of our study help, in a larger sense, to navigate society towards a more sustainable direction and towards achieving the Sustainable Development Goals by highlighting the remaining challenges of these broad objectives.

Background & Aims: Cognitive load theory assumes that the higher the learner's prior knowledge (i.e., the more expert the learner), the lower the intrinsic cognitive load (complexity) experienced for a given problem. While this is the case in many scenarios, there can be cases in which the converse is also true, resulting in more expert learners reporting higher intrinsic cognitive load than novices for the same problem. This can occur in relation to problems involving complex systems (e.g., ecological systems), for which novices' problem representations may underestimate problem complexity and therefore report lower intrinsic load than experts. This finding is borne out in the current paper. Samples, Methods & Results: In Study 1 with 118 participants from the Black Forest area in Germany, participants with higher levels of forestry and ecological expertise evaluated a problem relating to the restructuring of the Black Forest to adapt to climate change as more complex than did novices. In Study 2 (within‐subjects design, n = 66 primary‐school students), we conceptually replicated this finding in a domain more typical of cognitive load theory studies, mathematics. We found that higher prior knowledge also reduced the underestimation of the complexity of ‘tricky’, but frequently used, mathematics word problems. Conclusion: Our findings suggest that cognitive load theory's assumptions about intrinsic load and prior knowledge should be refined, as there seems to exist a sub‐set of problem‐solving tasks for which the traditional relationship between prior knowledge and reported ICL is reversed.

Developing students’ systems thinking is an often-posed demand in education for sustainable development (ESD) and science literacy. Several studies have shown that systems thinking can be fostered in students of different education levels. Therefore, science teachers who are required to teach ESD-relevant topics should be proficient in systems thinking and be able to transfer that knowledge effectively to their students. The research project SysThema (Systems Thinking in Ecological and Multidimensional Areas) investigated the effect of three courses designed to foster systems thinking in student teachers of biology and geography. Courses varied in their proportions of technical fundamentals of system science and didactical content for teaching systems thinking. To conceptualise systems thinking, a heuristic structural competence model for systems thinking was developed. This model served as the basis for a test in evaluating the courses in a quasi-experimental intervention study that employed a pre-, post- and follow-up test control group design. After the completion of the courses, a high effect of fostering systems thinking was found in all treatment groups compared to the control group.

Education for sustainable development (ESD) has been a task assigned to schools and universities since the mid-1990s. This global movement spawned ESD research in numerous fields, including, among others, didactics and educational sciences, as well as sustainability sciences. In this article, we analyze the state of research on reliable recommendations of means (more precisely, teaching and learning methods and procedures) to promote the ESD goals. Within the framework of systematic literature analysis, we compared and evaluated 17 scientific publications from the field of ESD. Using qualitative content analysis, we scanned the 17 articles for recommendations of means of ESD and the cited evidence for their effectiveness. The findings show two groups of recommended means, differing particularly in the degree of learner autonomy and the quality of evidence for their effectiveness. We discuss possible tasks that can be derived from these findings for didactic research on ESD, and we make a suggestion for further teaching action.
