Why we need Science in our life? Why, when, and how people should learn scientific facts and acquire skills originated from application of specific scientific methods? Whether Science education is limited exclusively with the mission to prepare students to their life in the world of Physical/chemical/biological objects or vice versa it has a special cognitive potential that gives rise to the ability of every person regardless on its professional and social occupation to solve problems more effectively? JBSE publishes articles in which our authors try to answer all these questions exploring the issues of science education in different contexts. At the turn of the millennium, people have met a lot of new realities referring to issues in technologies, psychology, social relations etc. The life has changed drastically during a few last decades and a lot of traditional things seem to be perceived completely differently. How all those changes influenced the attitude to Science, how this is reflected in social and humanitarian issues, and finally, which ways should be proposed for Science Education in new reality?

With the unprecedented crisis created by the Coronavirus pandemic, online teaching and learning became a global solution - embraced by the whole world - that tried to cover, at least in part, in part the problems encountered by the educational systems. An exclusively online format of teaching and learning proved to be a challenge for both the didactic and the learning process. Although the extant research during the pandemic is very abundant, there are few approaches addressing the different perceptions reported by university students enrolled in various programs. This research aims to explore the usefulness of online learning as perceived by civil engineering students, from a multidimensional perspective. A multidimensional model has been developed that manifests on four dimensions: social usefulness of online lectures, the usefulness of online learning platform, learning effectiveness, and, usefulness for school performance. The results show a relatively low perception of the online learning usefulness in an exclusively online educational context, which disables active learning through hands-on experience in laboratory and real-life building sites (considering the regular study process). The model has been cross-validated on a sample of students enrolled in various educational programs then the differences between samples have been analyzed and discussed.

Movies are informal teaching tools to make teaching relevant to a diverse group of students. The use of movies may enhance students’ interest in science, technology, engineering, and mathematics (STEM). They can be effective tools to build students’ interest in STEM fields and raise their awareness of STEM and STEM careers. This study purpose was to identify STEM-related topics in the movie “Hidden Figures” and determine preservice female teachers’ views of it. The study sample included 19 female students. A qualitative phenomenological design research method was used. Data were collected using “the Movie Hidden Figures” and a “Semi-Structured Interview” forms. Qualitative data were analyzed using semiotics and content analysis. Analysis showed that Hidden Figures focus mostly on the theme of “gender perception in science” as well as “design process” and “advances in technology.” Participants believed that the movie had messages mostly of negative gender perception in science. Despite that, movies emphasized that women can be mathematicians, engineers, and scientists as men. They also stated that gender equality is crucial in education. They also advocated that mathematics and engineering are essential for technological progress and female scientists can play a more active role for achievement.

This research examined whether incorporating learning progress (LPs) in teaching can help Japanese lower-secondary school students systemically understand science concepts. A teaching plan incorporating the learning progressions (LPs) concept was developed. Next, a lesson was conducted for 36 third-year students of a public lower-secondary school in Japan (Hiroshima Prefecture) from the unit of “Ions and Atoms.” Then, the portfolios used in the class and the assessment questions after the class were analyzed. The results show that some students understood the concepts systemically at the grade level indicated by the LPs; however, some students did not. The results of this study suggest the following: (1) teachers should examine the appropriate teaching methods in the target unit and incorporate teaching to allow students to engage with what they are learning; (2) students should understand the lower-level concepts related to the target unit based on LPs, and if the level of understanding is insufficient, teachers should incorporate time to review and reconstruct the concepts.

Science educators have highlighted the need to develop students to integrate knowledge across science disciplines to address real-world issues. However, there has been little research about the development of interdisciplinary assessment instruments. In this research, the instrument that measures the level of upper-secondary school students’ interdisciplinary understanding of environmental issues was developed and validated based upon Wilson’s Construct Modeling framework. After a pilot testing, the revised assessment instrument of interdisciplinary understanding covering five typical environmental problems comprised 14 multiple-choice questions and four constructed-response questions. Five hundred twenty-three eleventh graders, including 279 boys and 244 girls from mainland China, made up the research sample. The partial credit Rasch analysis has verified the reliability and validity of the interdisciplinary understanding instrument. In addition, the results of cluster analysis revealed that over half of the students could use some partially accurate scientific concepts and principles from two or more disciplinary perspectives to deal with a specific environmental issue. The validated instrument can provide insights for assessing and developing upper-secondary school students’ interdisciplinary understanding in science education.

Scientific evidence-based reasoning has been recognized as a form of reasoning that characterizes scientific thinking. This study questioned what scientific evidence means in the various types of scientific activities; that is, this study explored the nature of scientific evidence (NOSE). To do this, previous studies were examined to understand how scientific evidence was analyzed, evaluated, and utilized during the scientific activities of scientists or students in scientific or everyday situations. Through this process, seven statements were identified to describe the NOSE. This study explains these seven NOSE statements, constructs a process of scientific evidence-based reasoning as a structured form by reflecting these seven statements comprehensively, and discusses the practical implications for teaching science in schools. Finally, the limitations of this study are discussed, and possible directions for future studies are suggested. It is believed that the list of NOSE characteristics can provide a starting point for further elucidation and discussion of scientific evidence and helping students’ science learning in more authentic ways.
