Many instructors globally reported a lack of engagement in synchronous online sessions during the COVID-19 lockdowns. This article outlines the use of collaborative small group tasks mediated via breakout rooms in Teams during the 2020/21 academic year. The rationale for the activities, which are available for download, is described along with…

In December 2019, the institutional affirmative action "Onde elas estão?" ("Where are they?") was launched for the mitigation of gender inequality in the STEM disciplines in Brazil, coincidentally in the same period which the first reports of the COVID-19 pandemic appeared in the city of Wuhan, China. Unfortunately, when…

The study consisted of three articles. Article one aimed to determine if there were any significant difference in science graduate students' (SGSs') conceptions of the "consensus tenets" of the nature of science (NOS) with respect to demographic factors -- the SGSs' academic and research characteristics. The participants were SGSs from…

The concept of hybridisation is one of the most difficult concepts for chemistry students to grasp at all levels of learning. Research showed the students conceptual difficulty ranged from their lack of the prerequisite knowledge for grasping the topic hybridisation to chemical bond formation and orientations of atomic orbitals. This study…

The students' attitudes towards school subjects may influence their behaviour and various educational outcomes. The research aimed to test students' attitudes towards the subjects of Biology, Chemistry, and Physics, and to examine the associations between those attitudes and students' learning strategies and grades achieved. The study included 245…

This work applies a cultural historical activity theory (CHAT) framework to understand how the outcome of a high school laboratory task may be positively influenced without making changes to the hands-on practical task itself. Informed by cognitivism, novel practical instruction videos that were based on the same video but had different audio…

Informal learning (IL) venues such as museums, zoos, scouting, national parks, and community activities are increasingly recognized for their important role in enhancing the public understanding of science. Many benefits to students who participate in rich informal learning experiences are reported in the literature, including improvements in…

In this paper we present a qualitative analysis based on data collected by means of an eye-tracker tool, concerning the outcome of a mathematical analysis question administered to a group of candidates of university level or higher. One of the research aims is to highlight similarities and differences in the visual observation of the question…

This study investigated how modeling in chemistry affect second language learners' descriptions of polymeric concepts. The aim was to investigate how chemistry discussions mediated by representations, contribute to second language students' development in the language of chemistry. The study took place in three multilingual upper secondary…

To meet the demands of the Next Generation Science Standards (NGSS), teachers need to reconsider their current instructional practices, shifting from learning about scientific ideas to making sense of phenomena and solving problems using three-dimensional learning components. Project-Based Learning (PBL) provides a framework for creating…

Faculty in the Chemistry and Environmental Science programs at St. Mary's University in San Antonio, Texas, collaborated to develop an undergraduate course in Field-Based Environmental Chemistry. The course was developed and implemented as a 2-semester, 1-semester, and online, synchronous course offered during the 2020/21 COVID-19 pandemic. As…

A teaching team composed of a faculty member (lecture) and a graduate teaching assistant (lab) endeavored to engage students enrolled in several sections of the same organic chemistry course through the use of social media. Students were encouraged to follow both instructors on Twitter and were asked to share aspects of the class using the social…

This paper provides information about a multilingual (Portuguese, English, Spanish, Italian, and French) virtual card game for computers and smartphones. Facing the disruption caused by the COVID-19 pandemic, this game allows students to play remotely or face-to-face with friends in a fun and cooperative environment and review the topics related…

The problem of practice (PoP) in this dissertation in practice (DiP) focuses on the lack of motivation and engagement exhibited by career technical education (CTE) students within the traditional high school chemistry classroom as a response to textbook and teacher-centered pedagogy. This qualitative action research study utilizes a game-based…

This case study demonstrates teaching and learning activities in the school laboratory, and employs talk moves for the direct assessment of practical task effectiveness. By adopting a sociocultural linguistic approach (SCLA), learning chemistry is understood to be a discursive process in which knowledge is constructed through social interaction…
