The COVID-19 pandemic caused several educational challenges. Conducting laboratory experiments was an uphill task during the pandemic. Here, we developed a low-cost and reliable home-based experimental setup to teach column and thin layer chromatography (TLC) using silica gel granules available at home. Powdered silica gel, prepared by grinding…

Narrative texts have been advocated as tools to tackle science learning challenges, and there is even the proposal of a "narrative effect" on learning. We believe it is necessary to examine previous evidence on this effect, as well as to characterize the process of learning through science narrative texts more broadly. In this article,…

The current study investigated science identity development among Latinx university students selected for a critical race theory (CRT)-informed undergraduate research experience. Twenty students (12 female, 8 male; M[subscript age] = 22.00; SD = 2.77) enrolled in biomedical-related majors at a 4-year university responded to open-ended questions…

As an introduction to sound and vibration, the authors wanted their first-grade students to plan and conduct their own investigations. In this article, the authors share a series of investigations to help students explore the relationship between sound and vibration. By planning, creating, testing, adapting, and reflecting on the outcomes of the…

This study addresses suggestions for analyzing science teachers' pedagogical content knowledge (PCK) components and their interactions and these suggestions are expected to facilitate the analysis of science teachers' PCK, resulting in more accurate representations of PCK. Knowledge of the science curriculum, knowledge of students' understanding…

This study aims to investigate the situation of science teachers regarding out-of-school learning activities and to investigate how their participation in out-of-school learning activities as an observer within the scope of science courses creates a change in the situation of teachers. A case study was used in this study. Twenty-one science…

"Troso" woven fabric is a kind of weaving fabric produced in a village in Indonesia called "Troso." The aim of this study was to identify the detailed process of manufacture of "Troso" woven fabric and reconstruct it related to several scientific concepts. Research method started by observe several local cultures in…

This dissertation is in two parts: Part 1 of the study focuses on investigating the feasibility of delivering turn-on rhodamine-based fluorophores through Glucose transporters (GLUTs) for biomedical applications, both "in vitro" and in vivo. Fluorescent GLUT targeting probes are essential for analyzing transport activity, monitoring…

This study advances a concept of science religion encounter (SRE), with preliminary theorisation and shares findings on the extent and nature of such encounters reported by secondary religious education and science teachers. SREs are interdisciplinary engagements in classrooms involving subject knowledge from more than one subject. The researchers…

[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] In recent years, physics instructional labs have been under considerable research and development. However, there seems to be no shared understanding of how the assessment of instructional labs should be arranged to best serve students'…

Although most students in nonmajor biology courses will not enter careers in science, they will need a working understanding of biology and how it relates to their lives to make informed decisions on important topics that will affect their lives, including food, environment, energy, and health. This research seeks to improve on nonmajors'…

In our theoretical and conceptual article, we propose that the application of Niklas Luhmann's sociological systems theory as a difference-theoretical approach to the opening of science unveils an openness paradox. We describe and discuss the general concept of open science as currently proposed by UNESCO and posit that only by accepting the…

This paper addresses the fundamentals, structuring, and application of a Formative Dimensions for Green and Sustainable Chemical Education (Formative Dimensions -- GSCE) qualitative evaluation tool of experimental processes. This instrument was created considering the need to resignify laboratory practices in Chemical Education. Qualitative…

A cornerstone activity in undergraduate organic laboratories revolves around students running instrumental analysis on their products and interpreting their spectra. They are left to link the theory they have learned in lecture to practical spectral interpretation. Students often memorize benchmark interpretations of peaks, such as the broad…

Understanding potentiometry is a difficult task when students in initial courses of Analytical Chemistry are first introduced to instrumental techniques. The closest instrument to them is a pH meter, which is frequently used as a "black box", without a real understanding of how it works. Here we present the assembly of jelly modules that…
