I teach history of science at the University of Udine, Italy. My students – about 25 – frequently the second and the third year at the faculty of Letters and Philosophy (now called “Polo Umanistico”). They have to pass a sole proof in history of science. Therefore, in this editorial, I would like to face the problems connected with the teaching of history of science to students who have a scarce knowledge of mathematics and who in their future will have probably few contacts with science and its history. Thus, two problems are particularly difficult in this case: 1) to choose the subject properly; 2) to choose the appropriate educational approach. Obviously, the choice of the subject is always important, but if one teaches history of science in a scientific faculty, the situation is, in a sense, easier: for example, at the faculty of physics, one could select a specific course each year, i.e., history of mechanics in a certain period, history of electromagnetism in the 19th century, the theory of optics as it is developed by an author or a series of authors (Euclid, Witelo, Kepler, Snell, Descartes, and so on), etc. Each subject could be dealt with by facing the particular research of each scholar and entering the specific mathematical arguments. This is not possible in a humanities faculty. Thence, I would like to explain my choice and to trace some general considerations.

Collaboration and synergy among education stakeholders is a fundamental pillar for any educational reform success. The reported research analyses the state of collaboration and work dynamics that existed between natural science district officials and primary school teachers in the Eastern Cape Province, South Africa. Data were collected through interviews conducted with science district officials and teachers and policy document review. The results focuses on past previous experiences with officials as barrier towards effective collaboration, work dynamics between science district officials and science teachers in their districts, impact on and implications for curriculum reform implementation and professional development. It is argued that effective collaboration between district officials and teachers is a hallmark of curriculum reform success, teacher growth and success in the workplace, which result in student academic achievement. Effective collaborations are built around trust in individual’s professional integrity and are characterised by professional candour, appreciation of individuals and understanding. In conclusion, it is imperative for district officials and teachers to improve communication and strive for effective collaboration, mutual respect, and power sharing rather than domination of one group by the other.

The animal migration is one of the natural processes and is important not only for animals but also for people. Although this process is inseparable part of the nature, its incorporation into curriculum is on low level, not only in Czech Republic, but also in many other countries. The aim of the research was to identify lower secondary school students' knowledge of and misconceptions about animal migration and to identify if gender, grade and residence of respondents have an influence on it. The sample size was created by 184 Czech lower secondary school students. The researcher himself created the research tool. It was a test and consisted of 18 questions. The test questions were also analyzed by the proportional determination and also by the methods of descriptive and inferential statistics. The knowledge of migration was very low among lower secondary school students. The grade level had the strongest influence on the knowledge from the examined variables. In the conclusion part implications for pedagogical practice are suggested and also suggestions for the further research in this field of study.

This study established the effects of a web-based computer simulation on the conceptual understanding of the rate of chemical reaction and attitude of 66 first year secondary school (SS1) students in Niger state, Nigeria towards chemistry. A pre-test and post-test experimental design was used during which students were randomly assigned into either the experimental or the control group. The ‘Rate of Reaction Knowledge Test’ (RRKT) and the ‘Chemistry Attitude Scale’ (CAS) was administered. Classroom observations and structured interviews with the students yielded additional qualitative data. The results showed that a statistically significant difference was found between the groups and that the web-based computer simulation improved students’ development of mental models on rate of reaction in comparison to the students in the experimental group. The students in the experimental groups also indicated that they liked using the software learning tools. The findings support the notion that chemistry teachers should be trained or re-trained in the use of web-based computer simulations for teaching chemistry. It places an onus on educational authorities to procure web-based simulations for use in teaching chemistry and other science subjects in secondary schools.

This research aims to determine whether Problem-Based Learning (PBL) helps in fostering scientific creativity among fifth graders. Students’ scientific creativity (SC) was investigated in the product dimensions of (a) solving scientific problems, (b) understanding scientific phenomena, (c) advancement in scientific knowledge, and (d) improvisation skills with a technical product. A pre-test and post-test single group experimental design was employed. Pre-test measures on SC were administered to 232 fifth graders. Students participated in PBL hands-on activities that required solving open-ended problems. After these were completed, post-test measures on SC were assessed. Students' reactions to the PBL experience were also recorded. The results of paired sample t-tests showed significant differences in all product dimensions of SC, except in the understanding of scientific phenomena. Further analysis found significant differences among the creativity traits of fluency, flexibility and originality in each product dimension of SC, except in the originality in the advances of scientific knowledge. Students felt that the PBL activities were easy, fun, and interesting as well as a practical way of gaining and advancing science knowledge. Students also found their participation in sharing ideas in cooperative learning groups inspired them to be more creative. This research suggests that the PBL activities have a positive impact in fostering student’s SC in science lessons.

Science teaching plays an important role in the contemporary society, but nowadays, many high school students are often not interested in school science. The purpose of the study was to enhance the quality of teaching and to encourage learners to study science, making student learning more effective and meaningful. The opinions of different stakeholders was taken into account. In Italy, almost 200 participants, counting both teachers and students, answered a questionnaire concerning the following aspects of teaching and learning: situations, contexts, motives; basic concepts and topics; scientific fields and perspectives; qualification; methodical aspects. The results obtained showed the priorities and main gaps in current science education. In particular, scientific literacy should be essentially based on three concepts: the development of communication skills, the improvement of intellectual skills and the development of personality. Unfortunately the study has also highlighted that the approaches judged more effective are not really common in the current educational panorama.
