In an introductory biology course, we implemented a learner-centered, model-based pedagogy that frequently engaged students in building conceptual models to explain how genes determine phenotypes. Model-building tasks were incorporated within case studies and aimed at eliciting students’ understanding of 1) the origin of variation in a population and 2) how genes/alleles determine phenotypes. Guided by theory on hierarchical development of systems-thinking skills, we scaffolded instruction and assessment so that students would first focus on articulating isolated relationships between pairs of molecular genetics structures and then integrate these relationships into an explanatory network. We analyzed models students generated on two exams to assess whether students’ learning of molecular genetics progressed along the theoretical hierarchical sequence of systems-thinking skills acquisition. With repeated practice, peer discussion, and instructor feedback over the course of the semester, students’ models became more accurate, better contextualized, and more meaningful. At the end of the semester, however, more than 25% of students still struggled to describe phenotype as an output of protein function. We therefore recommend that 1) practices like modeling, which require connecting genes to phenotypes; and 2) well-developed case studies highlighting proteins and their functions, take center stage in molecular genetics instruction.

In 21st century learning, critical thinking skills are the main choice that must be mastered by students. This study aims to determine the effectiveness of local wisdom-based science teaching materials in improving junior high school students’ critical thinking skills. Most science teachers still apply teacher-centered learning, so students tend to be passive. This type of research is quasi-experimental with a pretest-posttest control group design. The study was conducted in the even semester of the 2019/2020 school year. The subjects of the research were grade VII students. Data collection techniques and instruments in the form of tests that include indicators of critical thinking skills. Data analysis used homogeneity test, Kolmogorov Smirnov normality test, independent sample t-test, and n-gain score. The results of the independent sample t-test are sig. (2-tailed) = 0,000<sig. α = 0.05. Students’ critical thinking skills in the experimental class were higher (N-gain score = 39.09%) than in the control class (N-gain score = 12.03%). Based on the study results, it can be concluded that there is a significant influence on the application of local wisdom-based teaching materials in improving the critical thinking skills of middle school students in the moderate category.

Many studies in the field of science education have emphasized the fact that systems thinking is a very important higher-order thinking skill which should be fostered during classes. However, more attention has been dedicated to the different ways of systems thinking skills assessment, and less to their enhancement. Taking this into consideration, the goal of our study was not only to validate secondary school students? systems thinking skills, but also to help students in the complex process of their development. With this goal, new instructional and assessment tools - systemic synthesis questions [SSynQs], were constructed, and an experiment with one experimental (E) and one control (C) group was conducted during organic chemistry classes. Namely, the instructional teaching/learning method for both E and C groups was the same in processing the new contents, but different on classes for the revision of the selected organic chemistry contents. The results showed that students exposed to the new instructional method (E group) achieved higher performance scores on three different types of systems thinking than students from the C group, who were taught by the traditional method. The greatest difference between the groups was found in the most complex dimension of systems thinking construct - in the II level of procedural systems thinking. Along with this dimension, structural systems thinking and I level of procedural systems thinking were also observed.

Abstract: The science learning process emphasizes providing direct experience to develop competencies in order to be able to explore and understand the nature around scientifically. students can gain direct experience, so they can add strength to accept and apply the concepts they have learned. Integrated science learning deals with the way students think and develop critical thinking skills. These skills include the ability to think critically, think creatively, and problem solving abilities. Modules are printed teaching materials that are designed to be independently studied by students, Module development is done to improve students' critical thinking skills.

Chemical bonding contains basic concepts that are used to understand almost any topic in chemistry. Several research results show that there are still many misconceptions. Therefore, teaching materials are needed that can provide a correct understanding of the basic concepts in chemical bonding materials. This study aims to produce inquiry model chemistry teaching materials with cognitive conflict strategies for Muallimat NW Pancor high school. The development method used definne, design, development and dissemination. Data analysis was conducted in the form of product validity tests and students' critical thinking skills tests. However, in this development research, it only stopped at the third stage. The data obtained were quantitative and qualitative. The results  is (1) the feasibility of the material was 84% (very feasible); (2) the systematic feasibility of the presentation is 85% (very feasible); (3) language feasibility is 85.33% (very feasible). So that overall the teaching materials produced are categorized as very feasible and can be used in chemistry learning.

Purpose The purpose of this paper is to explore multiple Canadian educators' experiences with the Map the System (MTS) competition, designed to foster and grow systems thinking capacity among students exploring complex questions. The challenge has been an opportunity for social innovation programs (from the nascent to the established) across Canadian post-secondaries to engage both with their own communities and with social innovators internationally, connecting social innovation spaces as part of their third mission. Across the organizations, students valued the interdisciplinary and systems thinking qualities, and organizations benefited from the external competition, there remain questions about organizational engagement in social innovation as a deeply transformative process internally. Design/methodology/approach All Canadian post-secondary institutions who participated in the 2020 MTS competition (17) were invited to a digital roundtable to discuss their experiences. Ten were able to participate, representing a range of post-secondaries (including large research institutions, undergraduate-only universities and colleges). To facilitate discussion, participants met to discuss format and topics; for the roundtable itself, participant educators used a google form to capture their experiences. These were summarized, anonymized and redistributed for validation and clarification. To reflect this collaborative approach, all participant educators are listed as authors on this paper, alphabetically after the organizing authors. Findings For students participating in MTS, they have built both their interdisciplinary and systems thinking skills, as well as their commitment to achieving meaningful change in their community. But MTS arrived in fertile environments and acted as an accelerant, driving attention, validation and connection. Yet while this might align with post-secondary education’s third mission, educators expressed concerns about sustainability, internal commitment to change and navigating tensions between a challenge approach and collaborative work, and internal work and national competition limitations. This complicates the simple insertion of MTS in a post-secondary’s social innovation-related third mission. Research limitations/implications This study was limited to Canadian post-secondaries participating in MTS, and therefore are not representative of either post-secondaries in Canada, or all the MTS participants although Canada is well represented in the challenge itself. Additionally, while the authors believe their approach to treat all participants as authors, and ensured multiple feedback opportunities in private and collectively, this is a deliberate and potentially controversial move away from a traditional study. Social implications More than half of Canadian universities (a subgroup of post-secondaries) had at least one social innovation initiative, but questions have been raised about whether these initiatives are being evaluated internally, or are triggering the kinds of transformative internal work that might be an outcome. Understanding the impact of MTS one example of a social innovation-related initiative can help advance the broader conversation about the place (s) for social innovation in the post-secondary landscape – and where there is still significant work to be done. Originality/value As Canada has only participated in MTS for four years, this is the first inter-institution consideration of its related opportunities and obstacles as a vehicle for transformational social innovation. As well, educators talking openly and frankly to educators reinforces the collaborative quality of social innovation across the post-secondary landscape.
