Plant nutrition is a complex subject at any educational level therefore, identification of student's ideas regarding this scientific concept is important in order to define the best instructional learning method. In this study, we conduct a cross-age comparison of the conceptual understanding of compulsory students and prospective elementary…

Practical work is critical to understanding science concepts. A case study was carried out to understand teachers' perceptions regarding practical work in Mankweng Circuit, South Africa. Four Grade 11 Physical Science teachers from different high schools were purposively selected. Data were collected through interviews, classroom observations, and…

The 'Moss Safari' activity was developed to assist with knowing which organisms to look for when observing a drop of water squeezed from moss for the first time. In this case study, the activity was introduced online to 34 trainee science teachers. This was followed by a post-session questionnaire evaluating their experience of the Moss Safari.…

The current mixed method study examined a Teacher Leadership Program (TLP) to determine to what extent participating teachers had changes in content knowledge (CK), practices, leadership skills, and leadership knowledge. The purpose was to determine if this program could be utilized to suggest a sustainable model for improving science education by…

Physics phenomena are widely viewed in daily life, and the technical nature of physics makes modern life seem to be simpler than it was many years ago. Physics teaching and learning, on the other hand, has not always been done effectively, especially in developing countries. This study aimed measured the effectiveness using mobile physics on…

This study used a quasi-experimental design to examine the effects of argumentative writing on non-science majors' conceptual understanding and the growth of their writing skills over a semester. To assess gain in conceptual knowledge, tests were given before and after the course; students in the writing group gained significantly more than…

This study investigated the effect of interactive computer simulation-supported inquiry on South African grade 8 learners' comprehension of atoms and molecular structures. Two sample groups of 34 learners per sample group were used, one acting as a control group who were exposed to a teacher-directed pedagogy while the experimental group used…

Educational videos are increasingly used to let students prepare lesson material at home prior to in-class activities in flipped classrooms. The main challenge of this teaching strategy is to stimulate students to watch these videos attentively before going to class. This paper describes the use of questions that pop-up within relatively long…

A Unit Operations Laboratory (UOL) is fundamental to undergraduate chemical engineering education. This article discusses a new course structure for the University of Kansas UOL and details for three new experiments covering the fundamentals of vapor-liquid equilibrium, fluid mechanics, and kinetics. Students apply knowledge from these courses as…

The overall aim of the present study is to study model-based teaching and the collaborative inquiry learning of chemical processes and physical phenomena in preschool, with a specific focus on the verbal communication established between teachers and children (4-5 years old). According to variation theory, learning is always directed at a specific…

This research aims to implement the guided inquiry learning model to improve the understanding of concepts and critical thinking skills of Vocational High School (SMK) students. The quasi-experiment method with the randomized pretest-posttest control group design was used to obtain data from students of one of the Vocational High Schools (SMK) in…

The Periodic Table of Elements is a valuable resource for chemists and all kinds of STEM professionals. However, it can be initially overwhelming and intimidating to some students. This hands-on lesson introduces abstract concepts in the periodic table through a tangible experience with simple toys and household objects. Students collaborate and…

The mole concept is one of the fundamental concepts in chemistry. However, a number of studies carried out in various countries have shown that teachers and learners face many difficulties in teaching and learning the concept. One of the underlying sources of teaching and learning difficulties of the mole concept identified in literature is the…

Chemical reactions far from equilibrium can exhibit oscillatory behavior. Full understanding of this phenomenon is outside of the school curriculum. However, the importance of such processes in life sciences and peculiar spatial and temporal patterns accompanying the reactions can attract the attention of IB Diploma science students. They will…

Purpose: This study aimed to determine the conceptual understanding (The Unit of Force) levels of seventh-grade students with different cognitive styles with different measurement techniques and to observe how the conceptual understanding levels measured by different measurement techniques are affected by their cognitive styles. Research Method:…
