This study examines the epistemic disciplinary knowledge that students consider when addressing a real food emergency that requires their engagement in inquiry and argumentation practices. The study comprised two phases: (1) designing an experiment to study the emergency and (2) evaluating the real outcome of the emergency. The participants were…

Background: Recent research investigating the conditions under which science teachers can successfully implement science education reforms suggests that focusing only on professional development to improve content knowledge and teaching skills--often referred to as human capital--may not be enough. Increasingly, possessing social capital, defined…

Little is known empirically about intraclass correlations (ICCs) for multisite cluster randomized trial (MSCRT) designs, particularly in science education. In this study, ICCs suitable for science achievement studies using a three-level (students in schools in districts) MSCRT design that block on district are estimated and examined. Estimates of…

The purpose of this study is to examine the effect of Digital Storytelling (DST) on the (a) academic achievement, (b) attitude towards physics and (c) self efficacy perception of secondary school students. This study consists of an experimental group and a comparison group which are formed by equal number of students. The six-weeks study adopted a…

A cluster-randomized trial (CRT) relies on random assignment of intact clusters to treatment conditions, such as classrooms or schools (Raudenbush & Bryk, 2002). One specific type of CRT, a multi-site CRT (MSCRT), is commonly employed in educational research and evaluation studies (Spybrook & Raudenbush, 2009; Spybrook, 2014; Bloom,…

The purpose of this paper is to provide a detailed description of the Monitoring the Future research design, including sampling design, data collection procedures, measurement content, and questionnaire format. This study assesses the changing lifestyles, values, and preferences of American youth on a continuing basis. Each year since 1975, at…

The present study used a multiple-baseline, single-case experimental design to investigate effects of three sequential experimental conditions on frequency of correct word sequences (CWS) and construction of simple sentences per 1-minute. Sentence Instruction, Frequency Building to a Performance Criteria (FBPC), and Paragraph Instruction comprised…

Studies on the effective teaching of biology have been continuously increasing since the 1800s. New teaching approaches have been purposed and tried out along the way. The multiple intelligences theory (MIT)-based approaches which give more importance to individual in educational settings can provide alternatives for meeting this requirement. An…

American educational leaders seek to educate children (regardless of race, class, or economic status) to become productive citizens. In order for our country to compete with other countries where students are well educated and highly motivated, we need to ensure that our educational system is equipped with the technology and tools that would allow…

This article presents an activity for early-in-the-year parents' night. The beginning of a new school year is an exciting time. The authors, as teachers, like to capture that excitement by engaging their 10th-grade biology students in an inquiry project demonstrating the nature of science and scientific inquiry. They developed the Next Step…
