Artificial photosynthesis is a promising approach to generate commodity chemicals using abundant chemical feedstocks and renewable energy sources. Despite its importance, affordable and effective hands-on classroom activities that demonstrate artificial photosynthesis and teach key concepts, especially for primary school students, are lacking.…

Martin Wagenschein's ideas of prioritising phenomena in making sense of science processes have influenced the German "Lehrkunstdidaktik" (art of teaching) approach. This article sketches a "Lehrkunstdidaktik" teaching unit inspired by Michael Faraday's "Chemical History of a Candle." It shows how primary and lower…

In a series of 12 project-based learning lessons, a group of seven fifth-grade students who live 200 miles from the coast explored their personal connections to the ocean. After completing a unit on the role of water in Earth's surface processes, the students investigated ocean acidification and how this pervasive ocean problem impacts their local…

Mechanistic reasoning, or reasoning systematically through underlying factors and relationships that give rise to phenomena, is a powerful thinking strategy that allows one to explain and make predictions about phenomena. This article synthesizes and builds on existing frameworks to identify essential characteristics of students' mechanistic…

The main purpose of this study was to investigate the effect of the Context-Based Approach (CBA) enriched by Prediction-Observation-Explanation (POE) on 5th grade students' conceptual understanding of the States of Matter, Heat and Temperature. In this study, quantitative and qualitative data collection methods were employed. The quantitative…

Incorporating an evidence-based approach in STEM education using data collection and analysis strategies when learning about science concepts enhances primary students' discipline knowledge and cognitive development. This paper reports on learning activities that use the nature of viscosity and the power of informal statistical inference to build…

The aim of the research is to assess the effectiveness of Virtual Lab (experimental group) compared to Physical Lab (control group) in the level of Science Process Skill mastery of topic salt experiment. This research also was done to compare the students' level of Science Process Skill mastery by gender and to find interaction effect between…

The right and wrong mental models that learners have about the changes in the matter have a great importance in understanding the basis of the chemistry. Therefore, the main purpose of this research was to identify students' misconceptions with regard to physical and chemical change and to come up with models to explain their understanding of this…

The aim of this study is to conduct a meta-analysis study to examine the effectiveness of the argumentation-based teaching method in terms of sample, subject, years and some variables (academic success, attitude, interest, etc.). Meta-analysis method was used in this study. In order to gather the studies included in meta-analysis, various sources…

There is a long tradition of teaching science through inquiry, with broad agreement about the form it should take. Students should investigate researchable questions; gather and analyse data; and develop and represent evidence-based claims. Authoritative teacher or textbook representations are generally used to guide this learning (Buckley &…

Science and engineering practices (SEPs) and crosscutting concepts (CCs) constitute a significant part of "A Framework for K-12 Science Education" (NRC 2012). As teachers, the role of the authors is to highlight the pivotal role that both scientific knowledge and the practices used to generate knowledge play in learning. This article…

Discrepant events are often used by science educators to incite interest and excitement in learners, yet sometimes their results are farther-reaching. The following article describes how one such event--dissolving packing peanuts in acetone--led to a change in the course of a college-level elementary science teaching methods class and to the…

These proceedings contain papers of the 3rd International Baltic Symposium on Science and Technology Education (BalticSTE2019) held in Šiauliai, Lithuania, June 17-19, 2019. This symposium was organized by the Scientific Methodical Center "Scientia Educologica" in cooperation with the Institute of Education, Šiauliai University. The…

This study examined the change in the two groups of senior primary school students' understanding of particulate nature of matter (PNM) before and after each group involved in related instructions, namely inquiry instruction with multiple representations (IIMR) and regular instruction (RI). Data were collected through a two-tier questionnaire, and…

There is an urgent need for more Latinx students to pursue careers in STEM related fields as this has historically been an unserved population in schools. This mixed methods study examined the impact of a summer STEM pipeline program focused on hands-on chemistry concepts for 28 Latinx students in the 5th grade. Findings include statistically…
