Public warning systems are an essential element of safe cities. However, the functionality of neither traditional nor digital emergency warnings is understood well enough from the perspective of citizens. This study examines smart city development from the perspective of safety by exploring citizens’ viewpoints. It investigates people’s perceptions of the ways in which they obtain warnings and information about emergencies involving health risks. Data were collected in the form of focus group interviews and semi-structured interviews in Finland, Germany, and Greece. The results suggest that people place a lot of trust in their social network, receiving text messages, and their ability to use web-based search engines in order to obtain public warnings. The study discusses the challenges identified by citizens in the use of conventional radio and television transmissions and sirens for public warnings. Based on the results, citizens demonstrate informed ignorance about existing mobile emergency applications. Our results imply that it is not sufficient to build emergency communication infrastructure: the development of smart, safe cities requires continuous work and the integration of both hard and soft infrastructure-oriented strategies, i.e., technological infrastructure development including digitalisation and education, advancement of knowledge, and participation of people. Both strategic aspects are essential to enable people to take advantage of novel digital applications in emergency situations.

This qualitative research explored the rationales of open-source development in cheminformatics. The objective was to promote open science by mapping out and categorizing the reasons why open-source development is being carried out. This topic is important because cheminformatics has an industrial background and open-source is the key solution in promoting the growth of cheminformatics as an independent academic field. The data consisted of 87 research articles that were analyzed using qualitative content analysis. The analysis produced six rationale categories: (1) Develop New Software, (2) Update Current Features, Tools, or Processes, (3) Improve Usability, (4) Support Open-source Development and Open Science, (5) Fulfill Chemical Information Needs, and (6) Support Chemistry Learning and Teaching. This classification can be used in designing rationales for future software development projects, which is one of the largest research areas in cheminformatics. In particular, there is a need to develop cheminformatics education for which software development can serve as an interesting multidisciplinary framework.

The transition from upper secondary school to higher education is a major change in students’ lives. Supporting students to make informed decisions based on a realistic view of higher education is one of the key elements to ensuring their motivation in future studies. Cooperation between upper secondary and higher education is one model for providing students with realistic views. However, little research has been produced from this cooperation. Therefore, the aim of this paper, based on mixed-method research, is to produce new insights into the opportunities provided by institutional cooperation by analyzing the views of Finnish upper secondary school principals (N = 94). The data were gathered using an online survey and analyzed via qualitative content analysis and descriptive statistics. The results indicate that principals consider cooperation with higher education institutions to be beneficial but there are some challenges in its implementation, such as the different structures of upper secondary schools and universities and inadequate information about possible opportunities. There are also great differences in upper secondary schools’ levels of participation. Distance to the nearest higher education institution and the size of the upper secondary school affected the participation models. There is a need to support cooperation between institutions to ensure equal possibilities for students, such as common structures, better information, as well as a multitude of different opportunities.

We describe a master’s level chemistry education course that was designed to support STEM education by strengthening the E component with an engineering approach. Engineering approach is a method of conducting projects systematically similar to professional engineers. In the course, the future chemistry teachers were given the task of building a measurement instrument using a single-board computer (SBC). In addition to course description, we present a pilot study, the aim of which was to explore the opportunities and challenges the engineering approach initiates with pre-service chemistry teachers trying to accomplish a SBC-based open engineering project. The study employed a qualitative research approach, using the course as the data collection platform. The collected data was analyzed using an inductive content analysis. The data analysis shows that an open SBC project is a good platform for learning and teaching future chemistry teachers about chemistry-driven STEM education, but it is very challenging to conduct. The main conclusion is that the engineering approach is a practical solution for strengthening the engineering in STEM education. To generalize these findings to a wider context, we suggest further research to improve the course using this study’s results and re-evaluate the approach in a new instance of the course.

By introducing the sustainable nature of chemistry to students—makers of the future—teachers, and teacher students we can promote their scientific literacy and increase understanding of the relevance of chemistry research and studies in sustainability. Ionic liquids are a topical example of innovation of green chemistry research offering many possibilities for sustainable chemistry education. This article describes how to develop research-based learning materials on ionic liquids using educational design research as a design strategy. The design process included two cycles and the initial design solution was iterated via a qualitative case study conducted with future chemistry teachers. The main result of this research is the designed context-based activity that engages learners with individual, vocational, and societal levels of relevance. In addition, the study produced new insights into future chemistry teachers’ perceptions of ionic liquids’ possibilities in a chemistry learning context. According to future chemistry teachers, ionic liquids are an interesting new context for laboratory learning and can increase interest in chemistry studies.

Currently, a growing number of learning institutions at all educational levels are including problem-based learning (PBL) in their curricula. PBL scenarios often utilise technology and socio-scientific Issues (SSI), which enables the simultaneous learning of content and creative thinking and working skills needed in generating new knowledge for the future. In this sense, using SSI and technological tools in PBL learning environments can be viewed as a starting point for acquiring and integrating new knowledge. However, there is no comprehensive knowledge regarding the possibilities of this approach. The objective of this systematic review is to produce this knowledge via the PRISMA method. The strategy is used to explore the effects of the described approach through implementations conducted at secondary and undergraduate levels. The data consisted of 33 research articles that were categorised via qualitative content analysis. According to the results, PBL scenarios exploit mainly local SSIs that link scientific knowledge with a meaningful context for students. Technology is principally used in offering technical support for teaching tasks. Lastly, these results are discussed from the technological pedagogical science knowledge (TPASK) framework perspective, which proposes guidelines for achieving the Sustainable Development Goals (SDG).

Abstract The focus of this systematic literature analysis is to provide a comprehensive review of earlier research on the utilisation of 3D printers in chemistry education. The objective is to offer research-based knowledge for developing chemistry education through following research questions: what kind of work has been done in the field of 3D printing in chemistry education; what kind of design strategies have been implemented; how 3D printing has been used in chemistry education research. The data consists of 47 peer-reviewed articles which were analysed via qualitative content analysis using a technological pedagogical content knowledge framework. Theoretical framework was selected because integrating 3D printing in chemistry education requires knowledge of chemistry, technology, and most importantly, pedagogy. Our research indicates that integrating 3D printing begins by analysing current challenges which are reasoned via pedagogical or technological content knowledge-based arguments. 3D printing was used for producing solutions (e.g. physical models) that support working with found challenges. In chemistry education research, 3D printing has mainly been used for printing research instruments; few studies have investigated its effect on learning or students’ perceptions towards it. There is a great need for comprehensive student-centred pedagogical models for the use of 3D printing in chemistry education.

The purpose of this descriptive case study was to develop pre-service chemistry teachers’ Technological Pedagogical Science Knowledge (TPASK) through novel computational chemistry modules. The study consisted of two phases starting with designing a computational chemistry based learning environment followed by a case study where students’ perceptions towards educational computational chemistry were explored. First, we designed an authentic research-based chemistry learning module that supported problem-based learning through the utilisation of computational chemistry methods suitable for pre-service chemistry education. The objective of the learning module was to promote learning of specific chemistry knowledge and development of scientific skills. Systematic design decisions were made through the TPASK framework. The learning module was designed for a third-year physical chemistry course taken by pre-service chemistry teachers in Chile. After the design phase, the learning module was implemented in a course, and students’ perceptions were gathered using semi-structured group interviews. The sample consisted of 22 pre-service chemistry teachers. Data were analysed through qualitative content analysis using the same TPASK framework employed in the learning module design. Based on our findings, pre-service chemistry teachers first acquired Technological Scientific Knowledge (TSK) and then developed some elements of their TPASK. Besides, they highly appreciated the combination of student-centred problem-based learning and the use of computational chemistry tools. Students felt the educational computational learning environment supported their own knowledge acquisition and expressed an interest in applying similar learning environments in their future teaching careers. This case study demonstrates that learning through authentic real-world problems using educational computational methods offers great potential in supporting pre-service teachers’ instruction in the science of chemistry and pedagogy. For further research in the TPASK framework, we propose there would be significant benefit from developing new learning environments of this nature and evaluating their utility in pre-service and in-service chemistry teacher's education.

The topics of nature, for example semiochemicals, are motivating topics, which can be used to teach organic chemistry at high school level. The history, classifications, a few important applications of semiochemicals, and an semiochemical that can be synthesized in the laboratory are presented. The laboratory synthesis is carried out through the well-known Fischer esterification reaction, which is easy to implement in a high school laboratory. Computer-based molecular modeling, based on free software, can be used for supporting the characterization of the synthesized molecule. This information can be used as orientation and motivating material for inquiry- and context-based high-school organic chemistry.
