Chemical reasoning takes many forms. The focus in this paper is on a reasoning process that facilitates using experimental evidence to make connections between macroscopic and submicroscopic domains, which we will refer to as "creating representation." It is a particular type of reasoning that has played a critical role in chemistry,…

This study systematically analysed, evaluated and synthesised published studies on 21stcentury skills and science achievement among secondary school students. By scouring 17 well-known online journal databases, 684 related studies were found. After the three-stage screening process, only 17 research papers were included in the study, which were…

The rise of technology and online approaches has challenged the traditional learning and teaching model for first year chemistry of formal face-to-face lectures and in-person laboratory sessions. The COVID-19 pandemic since 2020 has created a rapidly changing environment in assessment and learning experiences for students and led to rapid adoption…

Effective natural science teaching in primary schools helps students to form and change their conceptions about nature and natural processes. This is only possible through communicating about learners' existing misconceptions and the process of transforming them into correct scientific concepts -- using a socio-constructivist learning approach.…

This study aims to examine the thoughts of fourth-year pre-service science teachers about the nature of science. For this purpose, the study preferred the qualitative research method and phenomenology design. Participants consisted of nine pre-service science teachers. Participants wrote a self-evaluation report after the nature of the science…

This study aims to investigate the effects of authentic learning methods -- applied in science courses -- on the problem-solving skills and attitudes towards those courses. As a research design, a quasi-experimental design with pre-test and post-test control groups was used in the study. The data of the study were collected from 92 students at the…

Studies focusing on pre-service teachers have shown that the inclusion of the learning cycle model in a methods course result in improvement in understanding of and attitude toward the learning cycle model of inquiry. However, pre-service teachers' understanding and beliefs about the learning cycle model may remain varied and inaccurate and their…

This study was carried out in order to investigate the impact of implementing video-based predict-observe-explain (POE) on students' scientific literacy, particularly in chemistry's concept of salts. The hypothesis of this study was that students' scientific literacy would improve after implementing video-based POE within teaching, in the context…

Constructivist teaching and learning approach is one of teaching approach gaining popularity based on its principles of learner centered education. This study investigated the effectiveness of constructivist method of instruction on learning biology and challenges facing its implementation in secondary school students. The study design was…

Climate change and the resulting and related environmental and humanitarian outcomes are some of the fundamental challenges of the 21st century. Green chemistry, a relatively recent addition to the chemistry family, aims to reframe chemistry so that chemistry ethically and responsibly attends to its own environmental and human health impacts and…

This qualitative case study documents pedagogical changes from a traditional teacher-centred instruction to an inquiry-based integrated literacy/science instruction in an urban second grade classroom. Social constructivist learning, where teachers and learners engage in discussion, argumentation, shared collective discourse, guided practice and…

African township schools are characterised by cultural and linguistic diversity, hence, teachers have the dual task of ensuring that learners grasp scientific concepts, while also catering for the diversity in the learners' backgrounds. The study reported on here was aimed at investigating teachers' beliefs and practices in teaching life sciences…

This article reports the results of a meta-analysis of the effectiveness of 7E learning cycle in science teaching. Totally 35 different effect sizes from 24 experimental studies, comprising 2918 students were included in the meta-analysis. The results confirmed that 7E learning cycle have a positive effect on students' achievement. The overall…

The implementation of social constructivist approaches to learning science in primary education in Vietnamese culture as an example of Confucian heritage culture remains challenging and problematic. This theoretical paper focuses on the initial phase of a design-based research approach; that is, the description of the design of a formal, written…

The aim of the research reported in this paper was to explore students' "journey" towards conceptual understanding during an undergraduate course. The task that medical students face--to learn a substantial quantity of detailed knowledge and integrate into a coherent whole in a limited time frame--is demanding. Seven students were…
