The Beer-Lambert law is a fundamental relationship in chemistry that helps connect macroscopic experimental observations (i.e., the amount of light exiting a solution sample) to a symbolic model composed of system-level parameters (e.g., concentration values). Despite the wide use of the Beer-Lambert law in the undergraduate chemistry curriculum…

This research is quantitative research to determine the effect of using the Discovery Learning model to assist animation video on the critical thinking skills of students grade XI on the digestive system. The research method used is Quasi Experiment with a Non-equivalent Control Group Design and used purposive sampling. The research instruments…

This research aims to analyse students' conceptual understanding of chemical equilibrium matter using Physics Education Technology (PhET) Interactive Simulations. Students' misconceptions can be caused by the difficulty in connecting the sub-microscopic, macroscopic, and symbolic levels of understanding in chemistry. The study was conducted at a…

Before taking formal science education, learners usually construct preconceptions based on their daily life experiences, many of which are scientifically unacceptable misconceptions. In formal science learning, new concepts often contradict these misconceptions. To correct a misconception, it is first needed to create dissatisfaction about it by…

Numerous studies compared the effectiveness of various formats of video-based teaching, yet their focus has primarily been on relatively straightforward content, such as concepts and basic procedures. Research on the effectiveness of teaching complex content through different formats of videos remains limited. This study addresses this gap by…

Previous research suggests that everyday expressions are commonly used in students' descriptions of nutrient uptake. This study investigate a classroom context in year 5 with a focus on signs of scientific meaning-making about nutrient uptake with an animation as a resource in two different schools. In one of the schools there was also a teacher…

Redox titration problems are considered difficult for students to learn due to their abstract nature, the myriad amount of representations, and the mathematical competency required to learn and solve. The goal of this research project is to examine challenges students face in learning about redox titration-related problems, approaches they use in…

Going beyond ceremony to meaningfully integrate the lived experiences and narratives of Blacks particularly African Americans in the science curriculum, requires pragmatic research methodologies. K-12 science curriculum development neither considered the needs of African Americans nor were developed with Blacks in mind. Many questions arise…

In this study, we aimed to determine the effects of Web 2.0 animation tools for science education on 4th-graders' academic achievements and basic skills, as well as their attitudes and motivations towards science courses. The study was designed with pretest-posttest control group quasi-experimental pattern. The sample consisted of 4th-grade…

Some science subjects are often perceived to be difficult and boring by students due to their nature and the way they are taught. This study sought to check the effectiveness of the technology-enhanced instruction method with comprehensive use of virtual labs and animations in teaching nerve cells' (neurons and glial cells) structures and…

This paper determined the relative effect of animated and non-animated powerpoint (PPT) presentations on students' achievement in physics. A non-equivalent group quasi-experimental research design was adopted for the study, using a sample of 88 senior secondary two students drawn from secondary schools in Nsukka Local Government Area of Enugu…

This study compares students' explanations of the oxidation-reduction reaction between silver nitrate and copper metal after viewing a chemical demonstration and one of four different particulate-level computer animations. The animations differed in the way the ionic charges were depicted (shown or omitted) and the way the transferred electrons…

This study investigated the effect of visual anthropomorphic stories on students' understanding of the particulate nature of matter and their level of anthropomorphic discourse. This study employed a quasi-experimental research design with pretest and posttest control groups. Science activities supported by visual anthropomorphic stories were…

This research aims to support the "teaching of concepts" in the 3rd grade Life Science Course with activities. A quasi-experimental design (selective) with a pre-test and post-test control group, one of the quantitative research designs, was used in the research. Using songs, poems, rhymes, acrostics, stories, fairy tales,…

The purpose of this study is to examine the effects of different ways to use visualizations on high school students' electrochemistry conceptual understanding and motivation towards chemistry learning. Expanding upon a model-based learning approach (Khan, 2007), we adopted a VGEM sequence (View, Generate, Evaluate, and Modify) to create three…
