Formative assessment in science has long been reported to support students' scientific understanding. It involves teachers gathering assessment evidence, interpreting it in the light of learning goals and providing feedback to bridge the gap between students' current state of understanding and the desired educational goals. This study examines how…

Over the past 25 years, the Davidson College Physics Department has developed small computer programs called Physlets. These programs were written in Java and distributed as Java applets embedded in HTML pages. Physics teachers from around the world used Physlets to author interactive computer-based curricular materials for the teaching of…

This study uses high school transcript data from the National Assessment of Educational Progress (NAEP) High School Transcript Study (HSTS) to determine the validity of student-reported high school courses on the NAEP twelfth-grade student questionnaire. Given that the HSTS is not administered as part of every NAEP twelfth-grade assessment,…

The basic premise underlying this research is that scientific phenomena are best learned by creating an external representation that complies with the complex and dynamic nature of such phenomena. Effective representations are assumed to incorporate three key characteristics: they are graphical, dynamic, and provide a pre-specified outline of the…

In this paper we present a methodological approach for analyzing the transformation of interest in science through classroom talk and action. To this end, we use the construct of "taste for science" as a social and communicative operationalization, or proxy, to the more psychologically oriented construct of interest. To gain a taste for…

This study aimed at portraying the implementation of inquiry-based chemistry learning in the city of Jambi, Indonesia during the curriculum reformation era. The study included pre-existing supports for and situational beliefs towards the use of the strategy. The results of a questionnaire (n=99) revealed that inquiry had been minimally adopted in…

To investigate any possible differences in student engagement between project-based learning units and non-project-based learning units, this triangulation design-convergence mixed methods study followed a grade 10 teacher and her students as they completed science units on chemistry, aquaponics, and genetics. Student engagement was measured in…

The adoption and use of various eLearning systems to enhance the quality of education in secondary schools in Tanzania is becoming common. However, there is little evidence to suggest that students actually use them. Existing studies tend to focus on investigating students' attitude towards using these systems through surveys. Nonetheless, data…

An online curriculum about biological evolution was designed according to the "Promoting Evidentiary Reasoning and Self-Regulation Online" (PERSON) theoretical framework to support evidentiary reasoning and self-regulation. An efficacy study was conducted with 83 suburban high school biology students using design-based research methods.…

This research aims were to: (1) produce a PhET simulation-based learning device that who being used in physics learning activities by using Problem Based Learning (PBL) model to improve critical thinking skills of students MAN 3 Sleman in chapter work and energy, (2) knowing the effectiveness of learning medium in the form of PhET simulation in…

The aim of this study is to analyze the types of visual representations in primary and secondary science textbooks in Turkey. The sample of the research constitutes six textbooks prepared by private publishers for primary and secondary science courses (3rd -8 th Grade) in Turkey in 2018-2019 academic year. Document analysis design, which is one of…

The present paper reports upon the design and implementation of a novel practical work pedagogy that is shown to increase students' retention of practical procedures. The chemistry exams, for 15 to 16-year olds in England, will be assessed entirely through terminal examination questions from 2018. Longer term retention of learning is critical if…

This study uses graphs of conductivity measured by a microcomputer-based laboratory (MBL) to promote students' macro, micro, and symbolic representations when learning about net ionic reactions (NIR). A total of 54 students, aged 14-15 years old participated in this research, and were randomly divided into an experimental group (N = 27) and a…

This study explored the use of classroom physical activity (PA) in secondary science classrooms. To accomplish this, semistructured interviews were conducted with secondary science teachers (n = 11). Interviews were based on the constructs of the social-ecological model. Most teachers reported using classroom PA in some form--in-class breaks,…

In 2015, Liberty, (Missouri) Public Schools was updating resources for several content areas. Content consultant Diana Laufenberg, executive director of Inquiry Schools, had been working with secondary teachers to study options for the best and most current instructional practices in social studies. As teachers considered using online resources…
