I approach this paper from a critical retro-reflective stance, which explores borders both physical and educational through my pedagogical experiences in a high school in India, home experiences in the geographical borderlands of Nepal and India, and my current work in Nepal and the United States. All of the anecdotes or data originate from my…

Pedagogical content knowledge, PCK, a concept in teacher education requires additional focus and attention by pre-tertiary teachers to improve teaching and learning and learners' performance. The study adopted PCK model developed by Magnusson et al. (1999) to investigate senior high school (SHS) chemistry teachers PCK in teaching the concept of…

Too often, mathematics and science are taught in isolation from each other and from meaningful problems that matter to students. This book draws on the authors' experiences with teacher colleagues, including time spent in their classrooms co-developing and refining lessons. The core of their approach is to encourage learners to pursue solutions to…

The study explored the effects of robotic-assisted applications on the variables of academic achievement and problem-solving skills in the "Propagation of Light" unit of the 5th grade science course. The study employed the pretest-posttest control group design, one of the quasi-experimental methods. The study sample consist of 36 5th…

Critical thinking skills are one of the main competencies to be achieved in learning. Critical thinking skills can be taught through various methods, such as integrating through student worksheets (LKPD). Observations on the use of LKPD conducted at SMA Negeri 1 Parepare showed that the LKPD used did not support the development of students'…

The low scientific literacy in students is due to several factors such as lack of motivation, negative attitudes towards teachers, low self-esteem, and lack of confidence in self-ability. This study aims to analyze the effectiveness of the Numbered Head Together (NHT) learning model based on the Growth Mindset of scientific literacy and learning…

This study aimed to examine the impact of a context-based relating, experiencing, applying, cooperating, and transferring (REACT) strategy on the scientific reasoning (SR) abilities of tenth grade students. A mixed-method approach and convergent embedded experimental design were used. One hundred thirty-one students participated in the study in…

Each year, in middle and high school classrooms, secondary science teachers introduce their students to the periodic table of elements (herein the periodic table). According to the Next Generation Science Standards (NGSS Lead States, 2013), one of the performance expectations states that high school students should be able to, "Use the…

This small-scale, qualitative study uses educational design research to explore how focusing on argumentation may contribute to students' learning to engage in inquiry independently. Understanding inquiry as the construction of a scientifically cogent argument in support of a claim may encourage students to develop personal reasons for adhering to…

This study investigated the perception of aesthetic features within science among 73 pre-service science teachers and its implications for science education. We developed an analytical framework and questionnaire to administer to teachers. The findings revealed notable distinctions in how participants perceived aesthetic aspects, particularly…

This case study is an attempt to investigate how computer simulations can contribute to engaging students' active participation in knowledge creation through chemistry learning. Empirical data were collected through interviews, a survey, and a test on secondary school student performance in Rwanda. The findings reveal four main forms of…

Many factors in teaching chemistry influence students' soft skills and learning motivation. An attractive model is important in determining students' success in chemistry learning. This research aims to determine the level of soft skill abilities and students' learning motivation in implementing chemoentrepreneurship through project-based…

The results of a STEM educational program named "The air we breathe" implemented in a primary rural school in Greece as part of a National Research Project entitled "Diffusion of STEM (DI-STEM)" are presented in this paper. The educational program deepened in air pollution and intended to foster students' eight scientific…

Using a mixed-method approach, researchers examined college instructors' use of a virtual lab simulation library, Labster, students' perceptions of the simulations on their learning and future STEM plans, as well as data from the library to explore patterns of lab use and quiz scores. A detailed look at Contemporary Biology I and Biology II quiz…

Imagine having the opportunity to hear from 21 colleagues about their personal leadership journeys--and to get their advice. Leadership by and for Science Teachers is just such an opportunity. Author Rodger Bybee provides the insights and inspiration you need to rise to the challenges of leadership for the benefit of science education, your…
