The study determined the extent of the special science curriculum implementation in public secondary schools in the Division of Rizal for the school year 2022-2023. This research employed a descriptive survey design to determine the assessment of the teachers and school heads on the program's implementation. The findings revealed a commendable…

This paper reports the development and application of a low-cost multifunctional webcam spectrophotometer for the conduct of molecular absorption and fluorometric measurements. The equipment, which costs approximately US$20 to be fabricated, consists of a webcam, a diffraction grating, and a slit, all positioned inside an MDF box. Spectral…

Teaching modern physics in high school is of increasingly importance as it can offer students a more realistic and updated vision of the world, and can provide an opportunity to understand the most recent scientific discoveries. In this context, general relativity (GR) occupies a prominent place, since it is related to astonishing scientific…

There have been many calls for the development of discipline-specific argument writing interventions to integrate science-specific and general literacy standards and goals. Yet, adolescents with and without exceptionalities struggle to meet existing writing demands. This explanatory sequential mixed methods design draws from the strengths of…

The existing literature lacks a precise understanding of how online facilitation and dialogic discussions can positively impact students' comprehension of the Nature of Science (NoS). This study delves into the experiences of students and facilitators engaged in synchronous and asynchronous online dialogic discussions and e-facilitation to enhance…

This dissertation is an invitation into our beloved biology classroom. Weaving hermeneutic phenomenology and critical participatory teacher action research, this study investigated self as teacher and two cohorts of student participants in a high school biology experience utilizing an 'Aina Aloha praxis. Articulating my ongoing 'Aina Aloha praxis,…

In this brief experiment, students create a superhydrophobic surface as an application of polar--nonpolar interactions and redox chemistry. Half of a zincgalvanized steel strip is coated in copper nanoparticles through electroless deposition. A layer of nonpolar octadecanethiol is added to half of that copper surface. Students classify the three…

A laboratory activity is described for senior high school or first year undergraduate level students that illustrates key concepts linked to extractive metallurgy. This experiment demonstrates preferential binding of a methoxyphenolic oxime ligand to Cu[superscript 2+] in the presence of other transition metal ions in aqueous solution. The…

A study was conducted on how scientific laboratory lessons contribute to building arguments, both cognitively and socially. The population consisted of 12 second-year pre-service teachers at a college of education specializing in the teaching of biology and chemistry in middle school. The study examines the nature of the arguments students raise…

A versatile and portable apparatus was developed to demonstrate exciting visual displays of catalytic phenomena that introduce basic concepts in catalysis, renewable energy, and chemical safety, in order to pique scientific curiosity in a variety of audiences including middle and high school students, undergraduate and graduate students, and the…

We investigate students' misconceptions in electrostatics, direct current (DC) and magnetism which are important in electricity and magnetism. We developed and administered a multiple-choice questionnaire test to reveal students' misconceptions related to charged bodies, lightning, electric fields, electric potential, forces, DC resistive electric…

The U.S. Education system is founded on a Eurocentric focus of curriculum, and students of color are not achieving as high as white students on the National Assessment for Education Progress in science. This research aims to repay the education debt owed to students of color by decolonizing science curriculum through the implementation of lessons…

As part of a multiyear research project investigating the affordances of online citizen science (OCS) projects for enhancing school students' learning in relation to science and digital technology, teacher-researchers have designed and implemented classroom interventions incorporating one or more OCS projects. The project is situated in New…

High school science classrooms across the United States are answering calls to make computation a part of science learning. The problem is that there is little known about the barriers to learning that computation might bring to a science classroom or about how to help students overcome these challenges. This case study explores these challenges…

In this work, an alternative Experimental Didactic Kit for teaching resistors, capacitors and "RC" timing circuits was developed, using the Arduino platform technology, which is composed of a microcontroller and peripherals, due to the easy access to available teaching materials, enabling the reproduction of the prototype in the future…
