While some students will pursue careers in science, all will engage with multimodal science-based texts. The effective use of language skills is essential to support sense making in science. The purpose of this study was to examine how elementary teachers integrated language within their science instruction, and how their instructional enactments…

The main goal of the present investigation was to analyze the effect of motivation towards physics & chemistry on achievement in secondary school students. We focused our interest on the comparison between students who chose the subject when becoming optional in the Spanish educational system and those who opted out. Our analyses uncovered the…

The purpose of the study is to analyze gifted and talented students' project performances and views about them. In the study, explanatory sequential design, which is one of the mixed method research designs, was applied. In the quantitative phase of the study, project performances of the students were identified, while, in the qualitative phase,…

This article describes the development and validation of an instrument called science identities, expectations of success in science, values of science, and environmental attitudes (SIEVEA). The instrument is a convenient online survey that can be used to measure students' SIEVEA. First, 1764 high school students from 11 school districts in New…

Using many-facets Rasch measurement, this study aimed to detect and measure disciplinary context effects on student hands-on performance in terms of scientific inquiry competence. In Shanghai, China, a total of 251 eighth graders, from five junior high schools, participated in this study. The partial credit Rasch model was applied to help…

Traditionally, human anatomy is taught using cadaveric human or animal specimens, however such materials are not always available or are quite costly. Alternate instructional methods can include software, models, clay models, and illustrations. Unfortunately, while cost effective, these methods lack the ability to demonstrate the "in…

Quasi-experiments are common in studies that estimate the effect of instructional interventions on student performance outcomes. In this type of research, the nature of the experimental design, the choice in assessment, the selection of comparison groups, and the statistical methods used to analyze the comparison data dictate the validity of…

This study examined the relationship between students' (N = 229) concepts of size and scale and students' achievement in science and mathematics over a 3-year period. Size and scale are considered one of the big ideas in science that permeates disparate science and mathematics content areas, yet little is known about the relationship between…

This paper presents the findings of a three-year longitudinal study (Grades 9-11; N = 756 students in German secondary schools; mean starting age = 14.7 years) that explores the development of and the interplay between upper-secondary students' individual interest and conceptual understanding in chemistry. Students' individual interest was…

This research was aimed to analyze the effect of interaction between guided inquiry learning and cognitive style on students' science learning achievement. This study was a quasi-experiment with a 2×2 factorial design. The study was done with the fifth grade students in Singaraja City. The sample was selected using multi stage random sampling and…

PISA has extensively measured student achievement for over 15 years. But cognitive performance is only one aspect of success at school; another is general well-being. The PISA 2015 questionnaire included a comprehensive section on student well-being designed to understand students' mental health, satisfaction with life, aspirations and…

The purpose of this qualitative action research study was to describe a middle-level science teacher's transition to an inquiry-based, progressivist, student-centered model from a traditional, teacher-centered model as well to document the student-participants' perceptions of the new model. The study population consisted of one-hundred…

Organic Chemistry is considered by many to be the quintessential "weeder course", widely identified in the premed and STEM persistence literature as a gatekeeper to students interested in STEM or health fields (Barr, Gonzalez, & Wanat, 2008; Lovecchio & Dundes, 2002). There has therefore been considerable interest in determining…

Scientific literacy is very important for students, so that they can live in the 21st-Century, including solving problems that occur in everyday life. This study was aimed to get an overview of the high school students' scientific literacy profile in biology learning in the Surakarta City, Central Java, Indonesia. This research was ex-post-facto,…

Unequal access to qualified teachers for children of different socioeconomic status--also known as inequitable teacher sorting--has been increasingly put forth as one potential factor contributing to the socioeconomic achievement gap. Despite this, few studies have investigated cross-national differences in teacher sorting, and none have examined…
