This study aimed at designing a framework to help students develop a conceptual understanding of redox reactions, which draws on constructivist learning theory. This framework was in the form of participatory teaching and learning approach comprising Insight, Interaction, Task, and Forum. The framework was designed and developed based on the…

3D printing and simple electronics were used to create a polarimeter suitable for a variety of chemistry courses. This device allows instructors to demonstrate optical activity but is also easy to use and low cost enough to be widely available for student use, as well. The instrument uses an LED light source and detector housed in a 3D-printed…

The purpose of this study is to investigate the effectiveness of coupled inquiry-5E approach on the understanding of meiosis concept among pre-service teachers. The research design of this study is one-group design with a pre-test-post-test-delayed post-test. A total of 31 pre-service teachers from one public university involved in this study. An…

Dealing with student errors is a central feature of instructional quality. Teachers' reactions to a student's error and classmates' errors can be crucial to the success of a lesson. A teacher should respond appropriately in terms of motivational and learning-related issues so that the error can become a learning opportunity for students.…

Measuring the 3D position at any time of a given object in real-time automatically and well documented to understand a physical phenomenon is essential. Exploring a stereo camera in developing 3D images is very intriguing since a 3D image perception generated by a stereo image may be reprojected back to generate a 3D object position at a specific…

During the 1960s, Edgar Dale published the concept that learners are likely to retain more information if they see and hear information rather than just listen. Therefore, many educational applications have been created for students to learn theoretical concepts through visuals and in an interactive manner. Microsoft (MS) Excel has been used in…

There is a wide variety of ways for instructors to seek to improve diversity, equity, inclusion, and respect (DEIR) in chemistry through their instruction. One way is to talk with students explicitly about equity and injustice in science. We propose a curricular framework for teaching about equity as a way to improve DEIR in science classes at the…

In this paper is presented a pilot study for the investigation of the relevant factors within some experimental works carried out by students, after going through the learning unit "Movement and rest", which can be found in the chapter "Principles and laws in classical mechanics", from the physics curriculum for the ninth grade…

Professional development courses help teachers integrate new content knowledge into the high-school curriculum. Designing practical online courses for this purpose is challenging, particularly in emerging fields such as nanotechnology. In this study, we evaluated such a course in three complementary dimensions: (1) knowledge, (2) the complexity of…

Traditionally, assessing and grading students in science has been an exercise centered around points and percentages (Feldman, Kropf, and Alibrandi 1989; Prøitz 2013). However, with the introduction of the Next Generation Science Standards (NGSS) and the need to revisit grading practices stemming from the COVID-19 pandemic, an increasing number of…

We describe a simple STEM project for students to learn to measure atmospheric pressure by using a sensor of the type BMP180 together with the Arduino electronic platform. The collected experimental data, together with simple experiments, can be used to study the different pressure units and the relationship between pressure and force. Also, they…

This paper presents the design and reports on the use of a simple and inexpensive cloud chamber kit that is compatible with active learning, experiential learning, and project-based learning strategies. The kit was developed for use in a first-year undergraduate nuclear science seminar class at a university in the US. Diffusion cloud chambers are…

The current study determined the impact of the Argumentation-Flipped Learning (AFL) Model on the scientific process skills and academic achievement of students by performing a quasi-experimental pretest-posttest and retention control group design. The data were collected by scientific process skills test and concept test from a total of 112 5th…

Combining the face-to-face and virtual modality in a hybrid environment is a didactic strategy that currently provides the development of knowledge and skills in educational institutions at all levels, allowing the creation of educational environments without space and time restrictions. The objective was to describe the use by teachers in the…

Research on teaching and learning quantum physics (QP) frequently explores students' conceptual difficulties to identify common patterns in their reasoning. The abstractness of QP is often found to be at the origin of students' conceptual difficulties. Due to this abstract nature students resort to common sense reasoning or classical thinking when…
