Since pedagogical content knowledge (PCK) influences the teaching learning process, it has dominated research on teacher effectiveness. This case study explored teachers' enacted topic-specific PCK (TSPCK) during the biology lesson study stages: planning, teaching, and reflecting. The enacted TSPCK in two video-recorded research lessons was…

Advances in nanotechnology have drawn attention to nanotechnology education. The aim of this study is to determine awareness, exposure, and knowledge levels of science (physics, chemistry and biology) teachers about nanoscience and nanotechnology. Teachers (N=624) from secondary schools in Turkey comprised the working group. Descriptive methods…

The primary purpose of this study was to determine the confidence levels of School-based Agricultural Education (SBAE) teachers to integrate biology concepts in plant and animal science courses. The researchers also sought to describe the demographic characteristics of New Mexico SBAE teachers. This study used a descriptive-correlational research…

This paper investigates the teaching strategies used by secondary school science teachers in Swazi schools that perform well in national examinations. The performance of learners in science in these examinations is generally low, as indicated by the public examination results published by the Examinations Council of Swaziland. However, a few…

The main aim of our research was to determine whether the teacher is one of the factors influencing students' perception of biology as a school subject. The study also aimed to identify the influence of certain other factors in this regard, specifically: students' gender and place of residence, the number of biology teachers who have taught the…

Despite the importance of the theory of evolution to scientific knowledge, a number of misconceptions continue to be found among teachers and undergraduate students. The aim of the present study was to describe and characterise knowledge about evolution among 120 freshman undergraduate students of two natural sciences programmes (environmental…

The instruction of Natural Science subject in junior high schools, as regulated by 2013 Curriculum, is to be taught in an integrated way, combining Biology, Physics, and Chemistry subjects. The assessment of which is called authentic assessment. This current study described the instructional system especially the assessment system of Natural…

The current research is a descriptive study in which a survey model was used. The research involved chemistry (n = 26), physics (n = 27), and biology (n = 29) teachers working in Science High Schools and Anatolian High Schools in Turkey. An inventory that consisted of seven questions was designed to ascertain what teachers' think about the…

In this work we use research from science education on teacher framing and work from mathematics education on teacher noticing to develop new approaches to modeling teacher cognition. The framing literature proposes a dynamic cognitive model of teaching in which teacher epistemological framing, or moment-to-moment understanding of what is going on…

This report examines the patterns of placement of Teach for America (TFA) teachers and the achievement of the students they taught during the 2017-18 school year. The length of time current and former TFA teachers continue as employees of the District is also explored. TFA is an organization that recruits recent college graduates/professionals to…

Whether teachers' conceptions of NOS are reflected in their instructional planning and classroom practice remains an important research question. Consequently, this study investigated teachers' NOS views and their relationship to their classroom practice and delineated the factors that facilitate or impede this relationship. To achieve this, seven…

This study reports the effect of teachers' professional development in a two-year MEd program of High School Science Education, held from October 2010 until March 2012. Twelve out of the 33 teachers enrolled in the program participated in the study. The main research questions were: what are the teachers' perceptions of their own work and teaching…

Biological energy flow has been notoriously difficult to teach. Our approach to this topic relies on abiotic and biotic examples of the energy released by moving electrons in thermodynamically spontaneous reactions. A series of analogical model-building experiences was supported with common language and representations including manipulatives.…

In the age of educational accountability, national and statewide measures are assumed to secure and improve the educational quality. However, educators often wonder how much a new accountability measure may improve the actual teaching and learning practices when the agents of change (teachers) are not active participants of such educational…
