Peikos, George; Spyrtou, Anna; Pnevmatikos, Dimitris; Papadopoulou, Penelope – Research in Science & Technological Education, 2023
Background: It is stated that it is necessary that students develop their nanoliteracy in order to come up with everyday issues arising from Nanoscale Science and Technology (NST) applications, taking informed decisions and estimating the potential risks and benefits. Even though the inclusion of NST in compulsory education is supported by many…

Laszcz, Martyna; Dalvi, Tejaswini – Research in Science & Technological Education, 2023
Background: Nanotechnology, a multidisciplinary field with increasing societal importance, demands for an increase in research abilities and capacities. Yet, nanoscience and nanotechnology (NST) are largely inaccessible to K-12 students. This situation demands efforts in research towards bringing NST learning into K-12 classrooms. Purpose: The…

Baji, Fatima; Haeusler, Carole – Research in Science Education, 2022
In common with many other countries, the Iranian science curriculum does not introduce primary children to atoms and molecules but instead leaves the teaching of these concepts until high school. This paper challenges this practice and describes the changes in elementary Iranian children's understanding of atoms and molecules following a 10-h…

Cole, Merryn; Wilhelm, Jennifer; Vaught, Briana Marie-McKnight; Fish, Corinne; Fish, Hailey – Education Sciences, 2021
Research has shown that spatial ability plays a key role in understanding STEM (Science, Technology, Engineering, and Mathematics) content, including chemistry. Conservation of Matter (CoM) is an essential but challenging topic for chemistry students of all ages to grasp; it is often taught in a way where students memorize it but do not learn what…

Güven, Nalan Akkuzu; Uyulgan, Melis Arzu – Journal of Pedagogical Research, 2021
The present investigation aims to analyze the knowledge levels and chemical representation levels of pre-service primary school teachers (PPSTs) on the experiment of distillation. For this purpose, the cross-sectional survey technique, one of the quantitative research designs was employed. The study was carried out at a Faculty of Education in the…

Godfrey Bwayo Walwema – ProQuest LLC, 2020
Density is a difficult concept for students to understand because it cannot be directly observed. If students are to gain a deeper understanding of the concept of density, they need to learn about density at both the microscopic and macroscopic levels. Virtual reality provides an opportunity for learners to experience phenomena at microscopic…

James, Robin – Primary Science, 2019
Robin James was one of fifteen primary teachers who visited the Large Hadron Collider (LHC) at CERN, the European Organization for Nuclear Research in Switzerland. They were tasked with finding a way to interest students in particle physics after the visit. The science of really small things, such as atoms, is as relevant and intriguing to young…

Dunn, Justin; Ramnarain, Umesh – Education Sciences, 2020
This study investigated the effect of interactive computer simulation-supported inquiry on South African grade 8 learners' comprehension of atoms and molecular structures. Two sample groups of 34 learners per sample group were used, one acting as a control group who were exposed to a teacher-directed pedagogy while the experimental group used…

Düsing, Katharina; Asshoff, Roman; Hammann, Marcus – Journal of Biological Education, 2019
This study investigates students' conceptions of the carbon cycle with regard to the components they believe to be relevant to the carbon cycle, how they interrelate these components, the ways in which they trace carbon atoms, and the different levels of biological organisation they consider when doing so. A total of 142 students aged 13-16 years…

Sausan, Inas; Saputro, Sulistyo; Indriyanti, Nurma Yunita – International Journal of Instruction, 2020
Most junior high school students considered chemistry as a complicated science subject with an abstract concept, symbols, and terms that must be memorized. The difficulty of learning chemistry made students had low positive perceptions of chemistry. It was needed the right ways to introduce chemistry to them. The purpose of the multiple case study…

Liguori, Lucia – Journal of Chemical Education, 2014
Atomic orbital theory is a difficult subject for many high school and beginning undergraduate students, as it includes mathematical concepts not yet covered in the school curriculum. Moreover, it requires certain ability for abstraction and imagination. A new atomic orbital model "the chocolate shop" created "by" students…

Herrmann-Abell, Cari F.; Koppal, Mary; Roseman, Jo Ellen – CBE - Life Sciences Education, 2016
Modern biology has become increasingly molecular in nature, requiring students to understand basic chemical concepts. Studies show, however, that many students fail to grasp ideas about atom rearrangement and conservation during chemical reactions or the application of these ideas to biological systems. To help provide students with a better…

Anggoro, Florencia K.; Stein, Nancy L.; Jee, Benjamin D. – International Electronic Journal of Elementary Education, 2012
The present study examined the cognitive factors that influence children's physical science learning from a multimedia instruction. Using a causally coherent text and visual models, we taught 4th- and 7th-grade children about the observable and molecular properties of the three states of water. We manipulated whether the text was read by a tutor…

Skamp, Keith – Primary Science Review, 2005
If teachers decide to introduce the idea that the behaviour of matter ("stuff") can be explained by thinking about it as being made up of particles that exhibit particular properties, then they need to be aware of the learning difficulties involved. Before using this approach, therefore, more immediate consideration needs to be directed…
