The present study examined changes in high school biology and technology education pedagogy during the first year of a three-year professional development (PD) program using the INSPIRES educative curriculum. The Next Generation Science Standards (NGSS) calls for the integration of science and engineering through inquiry-based pedagogy that shifts…

This paper investigates how features of teaching practice may foster appropriation: learning that involves both deep conceptual understanding and transforming scientific discourse in a way that is significant for oneself. Data were drawn from classroom discussions during a unit on thermodynamics that took place in a high school in Italy. We…

High schools in South Dakota can drastically differ in size, facilities, and funding. However, each high school is required to meet the same state standards. This study focuses on high school biology courses, which have standards designed to "ensure graduates of South Dakota's public schools have the knowledge, skills, and competencies…

The purpose of this present action research study was to describe secondary students' feelings of self-efficacy in science, technology, engineering, and mathematics (STEM). Through a curriculum linked to a science fair project, the teacher-researcher focused on student-participants' perceptions of perseverance and task completion linked to STEM…

The research was focused on the teacher's opinions about the key and critical points of the lower secondary chemistry curriculum in the Czech Republic. Through the interviews with 40 chemistry teachers from four Czech regions was gained information about what teachers named as critical topics and what as key topics in early chemistry school…

The main aim of the research was to identify the attitude of pre-service and in-service Biology teachers towards the use of the Internet. In this research, the Internet Attitude Scale has been applied, a validated and standardized instrument. The scale was applied to 210 Biology teachers, of whom 155 are pre-service teachers and 55 are in-service…

The research is focused on the use of experimental calcium cycle in chemistry teaching at the lower secondary school. The cycle is based on four reactions: (1) thermal decomposition of calcium carbonate; (2) reaction of calcium oxide with water; (3) calcium hydroxide with hydrochloric acid; and (4) reaction of calcium chloride with sodium…

Students tend to be passive in learning activities if the media is less supportive. Module development as a learning medium can overcome the passivity of students. The purpose of this research was to determine the validity and feasibility of the guided inquiry-based module on Human Digestive System materials to improve students' argumentation…

This article explains how teams of special educators, science teachers, literacy consultants, and administrators can use the Disciplinary Literacy Observation Tool (DLOT) and accompanying planning tool to improve disciplinary literacy instruction in inclusive secondary science classrooms. The DLOT was developed in partnership with practitioners as…

In 2018, in response to the proposed elimination of physics at a predominately Hispanic and socioeconomically disadvantaged (SED) high school, the Northern California/Nevada chapter of the AAPT investigated school demographics and their effect on physics offerings in public high schools in our region. As access was a key issue, the focus was on…

Previous research only focuses on the difficulties and factors causing learning difficulties without any solution. This study aimed to identify learning difficulties, factors, and alternative solutions overcoming the problems of learning difficulties about viruses and bacteria. Data collection was carried out through the provision of a concept…

This study analyzed cognitive representations of knowledge from the chemistry of matter unit in a ninth-grade science textbook--the only authorized textbook in Saudi Arabia. It examined textual and visual information from two lessons in order to identify the textbook's introduction of concepts, linguistic context, integration of concepts, and the…

Peer assessment has been shown to advance learning, for example, by improving one's work, but the variance of learning benefits within or between studies has not been explained. The purpose of this case study was to examine what kinds of pathways students have through peer assessment and to study which factors affect them when peer assessment is…

We propose explicit and implicit approaches for the teaching of acid-base chemistry based on research into the history and nature of science (NoS). To support these instructional proposals, we identify four rationales for students to understand acid-base processes: daily life, socio-scientific, curriculum, and history of science. The extensive…

Classroom environment, family, and peers are important factors in influencing students' science learning. The primary aim of this study was to examine the effects of three environmental factors related to science learning (motivating science class, family models, and peer models) on students' approaches to learning science (deep approach and…
