This study examined the effect of design-based science instruction (DBSI) on sixth grade students' science achievement, as well as their development in relation to science process skills. 213 sixth grade students from three public schools participated in the study. A pilot was conducted in the unit of Systems of the Human Body and the main study…

Previous studies have documented the promising results from student-constructed representations, including stop-motion animation (SMA), in supporting mechanistic reasoning (MR), which is considered an essential thinking skill in science education. Our current study presents theoretically and empirically how student-constructed SMA contributes to…

This article examines Kazakhstan's approach to developing science, technology, engineering, and mathematics (STEM) competencies in future teachers by analyzing educational programs (EPs) and key aspects of STEM education implementation. The purpose is to provide an in-depth understanding of Kazakhstan's strategy for developing STEM skills in…

The goal of this study was to evaluate the effectiveness of organic chemistry textbooks in developing student representational competence skills with eight representations of molecular structure (Lewis structures, Kekulé structures, condensed structures, electrostatic potential maps, skeletal structures, dash-wedge diagrams, Newman projections,…

The results of a STEM educational program named "The air we breathe" implemented in a primary rural school in Greece as part of a National Research Project entitled "Diffusion of STEM (DI-STEM)" are presented in this paper. The educational program deepened in air pollution and intended to foster students' eight scientific…

Development of scientific explanation abilities in students is an important aspect in science education. However, traditional learning methods such as textbooks and PowerPoint presentations are often less effective in improving skills due to lack of student interactivity and involvement in the learning process. This study aimed to analyze the…

Being scientifically literate is an essential twenty-first century skill for every individual navigating today's complex world and science inquiry skills are seen as an important capability of a scientific literate person. However, teaching science inquiry skills requires specific competences and is often challenging for teachers. Understanding…

Integrated Science Process Skills online learning cannot be taught optimally so learning media are needed that can teach integrated, interactive, and practical SPS. One such media is an e-module. This study aimed to determine the feasibility and effectiveness of Guided Inquiry-Based e-module, or Mosiry, in improving Integrated SPS of Class XI…

This paper aims to review and assess the strategies available in literature to improve the practices of science process skills (SPS) among students. SPS encompasses the mental and physical activities of students in collecting and organizing information and then using the information to make predictions, explain phenomena, solve problems,…

Within the eukaryotic cell, the actin cytoskeleton is a crucial structural framework that maintains cellular form, regulates cell movement and division, and facilitates the internal transportation of proteins and organelles. External cues induce alterations in the actin cytoskeleton primarily through the activation of Rho GTPases, which then bind…

Computational thinking (CT) skills are essential with the rapid advancement of technology. Developing CT attitudes in students is also required for improving CT skills. On the other hand, science process skills are also emphasized in high school physics classes. This study aims to design and implement collaborative modeling-based learning for high…

We present the development and evaluation of "da Vinci's Curse", a chemistry escape room experience designed to consolidate laboratory skills in a fun and interactive setting. Inspired by the maestro, Leonardo da Vinci, the escape room challenges students to complete a series of puzzles in teams to escape "da Vinci's Curse".…

This experiment introduces undergraduate organic chemistry students to analysis and interpretation of Fourier transform infrared (FTIR) spectra through characterization of postconsumer plastics. Students use FTIR spectra to identify and differentiate the common recyclable polymer resins #1-6: polyethylene terephthalate (PETE), polyethylene (HDPE…

When teaching STEM courses, it is important to introduce state-of-the-art techniques. Students need to learn how to conduct experiments, analyse data and choose the most effective approaches to address meaningful situations. Here we present the assessment of the implementation of a structured inquiry-based activity aimed at teaching students about…

Relevant literature has an unexplored question on how prediction-observation-explanation (POE) worksheets affect science process skills of students with mild intellectual disabilities (SMID). Therefore, this research aimed to examine the effect of POE worksheets developed for the "matter and its nature" subject on SMID's science process…
