This research is concerned with how children's processes of imagination, situated in cultural and social practices, come into play when they invent, anticipate, and explore a problem that is important to them. To enhance our understanding of young children's learning and meaning-making related to science and sustainability, research that…

The article examines a number of links between the metaphorical uses of the concept of metamorphosis in literature and the various changes of the meaning of the concept that took place at the beginning of the modern scientific age between the 17th and 19th centuries, a period during which the notion of metamorphosis resurfaced in conflict with…

A 4-week mini-project is proposed for an experimental Physical Chemistry course applied in Food Science training. Activities include preparation of beet extract for the extraction of betanins and analysis of the kinetics of betanins in thermal degradation at three temperatures (60, 70, and 80 ºC). In addition to developing common laboratory…

The current educational climate, featuring standards-based reforms and reliance on summative assessment and managerial control has strained the professional work of teachers by simultaneously demanding compliance with reform effort and control of classrooms while expecting in-depth professional learning to shift their pedagogical strategies to…

Scientific disciplines including mathematics, physics, and chemistry tend to adopt online resources, including websites and web applications, to demonstrate physical experiments and simulate scientific phenomena that are hard to observe and investigate in real world. The present study examined the existing collections of the websites and web…

Sustainable development is a "durable development" that is systematic and long-term development of countries ensuring strong relationship between societal and environmental security with economic progress. The concept of sustainable development is essential for pre-service teachers to realize because the country is on its way to progress…

Students in one-on-one tutoring learn best when tutors elicit their constructive responses to scaffold them. Tutors' non-eliciting explanations, in contrast, seem to be less beneficial for learning. Usually, tutors use less eliciting strategies than would be optimal. They, however, seem to use more eliciting in procedural domains (e.g.,…

In the paper, the results of a study into a problem of cognitive barriers (difficulties) related to the third component of a pedagogical triad "how to teach what to teach to how to be learned study" are reported. At the first stage, methodical approaches to academic performance rating for students learning mathematical and…

In the context of transformation of the higher education landscape by Knowledge Society imperatives, there is an increase in academics' external engagement, especially in the fields of hard sciences. This trend is noticeable in various European countries with different higher education models, but rather limited knowledge in understanding the…

Current technology has the capacity for affording a virtual experience that challenges the notion of a teaching laboratory for undergraduate science and engineering students. Though the potential of virtual laboratories (V-Labs) has been extolled and investigated in a number of areas, this research has not been synthesized for the context of…

The topic of chemistry safety was included at the margins of traditional chemistry education in China. In order to understand the concerns of the safety issues based on the new chemistry curriculum in the mainland China secondary school, this study analyzed old and new secondary chemistry curriculum standards via the Natural Language Processing…

Science education is facing a challenge of students who are losing interest in learning science subjects including chemistry. This research provides a review of literature that emphasizes on the factors affecting secondary school students' attitudes toward chemistry. Thirty-six studies were selected in Google scholar and ERIC database in the time…

This study investigated preservice classroom teachers' views of distance education science laboratory (lab) activities (DESLA). The study adopted a phenomenology design, which is a qualitative research method. The sample consisted of 34 students (25 women and nine men) from the department of classroom teaching of the education faculty of a public…

The initial period of young teachers' careers is always significant in developing their professional capability. This is when teachers start coming into contact with practical teaching, which is more diversified than the theoretical training at the University. In this research, the authors propose a process of combining the Lesson Study model with…

The purpose of the present study was to investigate pre-service science teachers' perceptions of science teaching. To this end the participants' perceptions of their pedagogical knowledge (PK) and pedagogical content knowledge (PCK) were examined. Furthermore, it was aimed to investigate how pre-service science teachers' perceptions were differed…
