This research explores the effect of mental model-based learning on understanding school chemistry. The learning activity included group discussion, presentation and class discussion. Pre-service chemistry teachers (PCT) analyzed school chemistry topics in relation to essential underlying concepts. The development of mental models was monitored…

Electricity and magnetism are fundamental areas of physics and are integral to science curricula at various educational levels. However, this area has been reported to contain several concepts that students find challenging, leading to perspectives that diverge from scientifically accepted views. This study examines the errors made by physics…

The purpose of the present study was to examine the effect of individual and school average achievement on students' self-concept in science. The data of the last four Trends in International Mathematics and Science Study (TIMSS) cycles were used, and a two-stage individual data meta-analysis was conducted to examine the relationship between…

The purpose of this research is to determine the scientific literacy levels of students in 9th, 10th, 11th and 12th grades of high school by using the scientific literacy research test. In the study, it was investigated whether there is a significant difference in scientific literacy among students studying at different levels in secondary…

Lack of proper laboratories and inadequate facilities have become some of the factors affecting chemistry practical in Nigeria which therefore affects students' performance. While there were many studies conducted on the effectiveness of mobile learning, literature remains very scarce in the Nigerian context. In order to tackle this problem, using…

Achieving deeper and permanent learning has always been the focus of teaching force. This purpose is independent of the teaching level or subject matter. Pre-service teachers' lack of interest and inability to connect learning levels are partly cited for their inability to develop this deeper and permanent learning of science concepts. In this…

One of the most important problems of today's science education is the misconceptions and lack of knowledge that arise due to the science concepts not being learned in depth and meaningfully. For this reason, in this study, misconceptions, lack of knowledge, and scientific knowledge levels of science teachers about liquid pressure, which is one of…

This study developed and validated the Science Practice Scale (SPS) and investigated the implementation of scientific teaching practices by Grade 8 science teachers in Jordan. The responses of 235 8th grade science teachers who participated in the Trends in International Mathematics and Science Study [TIMSS] of 2019 were analysed using the Rasch…

Assessing preservice' higher order thinking skills (HOTS) in science and mathematics is essential. Teachers' HOTS ability is closely related to their ability to create HOTS-type science and mathematics problems. Among various types of HOTS, one is Bloomian HOTS. To facilitate the preservice teacher to create problems in those subjects, an Android…

Educational researchers have been interested in studying teachers' professional identity to understand this dynamic and multifaceted construct within personal and professional processes through different experiences. In this study, we designed a qualitative case study with Cultural--Historical Activity Theory (CHAT) to examine physics teachers'…

A central topic in Bioelectricity is the generation of the extracellular potential that results from the propagation of a transmembrane action potential along the muscle fiber. However, the way in which the extracellular potential is determined by the propagating action potential is difficult to describe, conceptualize, and visualize. Moreover,…

The purpose of this research is to examine the impact of activities based on scientific process skills on problem-solving skills of 4th grade students in science lessons. In the study a non-equivalent control group pre-test and post-test design type of quasi-experimental method was used. The research study group was composed of 30 students with 15…

India's National Science Talent Search (NSTS) examination (1963 to 1976) was imagined and implemented by some top scientists of the period. It aimed to identify "talented" secondary school students with an aptitude for science and mathematics. Selected students attended undergraduate summer schools, did research in special labs during…

Here, we describe the development and validation of an automatic assessment system that examines students' hand-drawn visual representations in free-response items. The data were collected from 1,028 students in the second through 11th grades in South Korea using two items from the Test About Particles in a Gas questionnaire (Novick &…

Biology education plays a vital role in nurturing the understanding of learners about the intricacy of life. Various efforts have emerged to strengthen learning biological concepts but there were still studies that showed that learners have low mastery in some aspects. To determine how well students understood various biological topics, including…
