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...

This qualitative research explored the rationales of open-source development in chemin-formatics. 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 cheminformat-ics has an industrial background and open-source is the key solution in...

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 providi...

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 me...

In a growing revolution driven by information technology, computational science (CSc) is indispensable for solving complex problems. Thus, CSs has been recognized to be a vitally important application of computational capabilities to understand and solve complex problems in the real world [President's Information Technology Advisory Committee (PITA...

The aim of this research is to study what kind of relevance do novice lower-secondary pupils experience when they use computer-based molecular modeling (CBMM) for the first time. CBMM offers many possibilities for chemistry education. However, it has not been studied at the lower-secondary level. This research was conducted via two research questio...

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 possi...

This perspective paper analyses the possibilities and challenges of using cheminformatics as a context for STEM education. The objective is to produce theoretical insights through a SWOT analysis of an authentic educational cheminformatics project where future chemistry teachers engineered a physical 3D model using cheminformatics software and a 3D...

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...

Teaching the fundamentals of chemical kinetics on the college level is challenging to teachers and students alike due to its abstract nature of concepts and limited connection with real context applications. This study consisted of two phases starting with designing a chemistry education for the sustainable development-based learning environment of...

Radiochemistry faces a well-documented training and recruitment crisis. Older radiochemists are retiring, and fewer young people are studying radiochemistry. In turn, this is leading to a shortage in newly qualified radiochemists, as well as a loss of historical knowledge (as know-how is often not passed-on). Here, we analyzed the relevance of the...

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...

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...

The lack of relevance is a major challenge in chemistry education. In the last two decades, a lot of research and development projects for increasing the relevancy have been conducted in all educational levels, expect in chemistry teacher education. This research is filling this knowledge gap by investigating what kind of learning methods in pre-se...

The science lab ChemistryLab Gadolin has been named after an internationally fa-mous Finnish Professor in Chemistry, Johan Gadolin (1760-1852), the father of Finnish chemical research. He emphasized the fact that inquiry has a central sig-nificance in the teaching of chemistry, which is why it also forms the basis for the operations of Gadolin. Joh...

Molecular modeling is an essential tool for chemistry teachers. It can be used for anything from student-centred activities to teacher-oriented visualizations and evaluation. This book offers theoretical insights and hands-on modeling activities. The goal is to learn how to implement molecular modeling in chemistry teaching. The exercises are perf...

Information and communication technology (ICT) has been successfully used to promote children's, youths' and teachers' competence in mathematics, science and technology in Finland through the LUMA Centre Finland. The LUMA ecosystem (LU stands for science and MA for mathematics) is a social innovation based on collaboration between 11 universities (...

Se on rakennettu Jsmol-kirjaston päälle, joka on avoimen lähdekoodin JavaScript-kirjasto molekyylien visualisointiin. Edumol tarjoaa monipuolisen kemian opetuksen visualisointiympäri...

This article discusses the historical development, current state, and needs future development of electronic learning environments for chemistry education. The study is by nature a theoretical literature review. Its aim is to canvass how the requirements related to chemistry learning environments have changed over time. By understanding the history...

The aim of this research was to design nanotechnology teaching material that is interesting to the pupils, and brings out the significance of chemistry and technology in society as well as supports the development of scientific literacy. The research was conducted as a design research that included four phases: 1) theoretical problem analysis, 2) d...

This paper introduces a new collaborative model for design-based research (DBR), model-based design research (MBDR), in which the design process is carried out through model-based reasoning (MBR). The objective of the paper is to discuss how MBDR can be used as a method for educational innovation, which is a social transformation occurring when a c...

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 we...

This poster describes a pilot case study, which aim is to study how future chemistry teachers use knowledge dimensions and high-order cognitive skills (HOCS) in their pre-laboratory concept maps to support chemistry laboratory work. The research data consisted of 168 pre-laboratory concept maps that 29 students constructed as a part of their chemis...
