This article examines the impact of a professional development program aimed at encouraging high school teachers to include more modern physics in their enacted classroom curricula through improved content and pedagogical knowledge. The program was implemented with 17 high school physics teachers (three were the focal point of this study) in…

The performance in biology at the secondary level has not been as good as expected. This has been a matter of concern. Thus, there has been a continuous focus on exploring newer innovative learner-centered and friendly instructional strategies to enhance understanding and retention in biology. This study, therefore, determined the effects of…

Scientific literacy is an important skill for students' success, given the characteristics of today's society. However, not all students have a natural predisposition toward science, chemistry in particular. Considering the relevance of transdisciplinary learning, schools should foster the scientific abilities for which students may have less…

The current work explores the secondary school teachers' and students' perception on web-based discussions in teaching and learning and its potentiality to enhance students' performance in organic chemistry. A mixed approaches typically interviews and achievement tests were applied for collecting qualitative and quantitative data respectively for…

The present work describes a simple hands-on experiment kit for colorimetric quantification of ferric (III) ion (Fe[superscript 3+]) in an aqueous medium using anthocyanin extracted from "Ruellia tuberosa" L. as a green indicator. The extraction of a high amount of anthocyanin was easily accomplished by using only hot water instead of an…

The aim of this study was to determine the in-service training needs of physics teachers for the inquiry-based curricula. The survey method was used in the research. In-Service Training Needs Determination Questionnaire for Physics Teachers developed by the researchers is consist of three components, demographic information and teaching profession…

The dynamic study of pendulum systems is considered an indispensable subject for physics and mechanics students in colleges and high schools. In this paper, a detailed methodology is given concerning the use of smartphones in pedagogical practical work for studying the dynamics of pendulum systems. Whereas, three aspects have been discussed…

Many high schools, two-year colleges, and universities offer a conceptual physics course for non-science students who have to take a basic science course. The students often enter the course unmotivated and may eventually withdraw. So, how do we make the course interesting enough for these students to gain the knowledge we desire and, more…

Students who aim to become physics teachers for secondary education partake in physics courses together with other physics students. The aim of this study is to understand what is valued, taken for granted, and possibly reproduced in physics teaching given for future secondary school physics teachers. This study is based on observations in…

There are many studies related to gender representation in science textbooks. However, less attention has been paid to the ways in which physics textbooks portray women: how women are situated in occupations or works, laboratory activities, and achievements, or to their characters in relation to women's stuff. This textual analysis aims to fill…

This study aims to investigate how girl students can be empowered through development of critical thinking skills in science. The researcher was interested in studying the effectiveness of Kolb's experiential learning in developing critical thinking skills of secondary school girl students. One group pretest-posttest design was used for this…

A curricular Delphi study was carried out to help improve and develop scientific training for secondary school students in Spain. Using the Delphi method, the authors analyzed the degree of consensus among more than 100 stakeholders' answers to the question, "What aspects of science education are considered desirable for a (Spanish)…

Research has shown that spatial ability plays a key role in understanding STEM (Science, Technology, Engineering, and Mathematics) content, including chemistry. Conservation of Matter (CoM) is an essential but challenging topic for chemistry students of all ages to grasp; it is often taught in a way where students memorize it but do not learn what…

The integration of socioscientific issues (SSI) into science teaching requires that teachers manage classroom discussions in which various perspectives are considered and students' contributions are recognized. The present study aimed to provide knowledge of how classroom discussions on SSI can be structured and implemented to pursue specific…

In response to calls for curricular materials that integrate molecular genetics and evolution and adhere to the K--12 Next Generation Science Standards (NGSS), the Genetic Science Learning Center (GSLC) at the University of Utah has developed and tested the "Evolution: DNA and the Unity of Life" curricular unit for high school biology.…
