Research on translanguaging in science and engineering education has grown rapidly. Studies carried out across diverse contexts converge in their commitment to fostering equity in science and engineering learning for linguistically marginalized learners. However, the rapid growth of this research area has exposed different approaches to…

Design-based learning (DBL) offers opportunities to support students' content understanding. Previous DBL studies reported different effect sizes by using the data from one participant group. The goal of this study was to conduct a meta-analysis that would give a comprehensive picture of how DBL is connected to student achievement in different…

This study explores the role of unconventional forms of classroom assessments in expanding minoritized students' opportunities to learn (OTL) in high school physics classrooms. In this research + practice partnership project, high school physics teachers and researchers co-designed a unit about momentum to expand minoritized students' meaningful…

Developing understanding of models and proficiency with modeling practice is challenging for both teachers and students. This 2-year study first investigated existing instructional strategies employed by teachers while teaching Earth and Space Science with dynamic physical models. Summer professional development introduced a conceptual framework,…

The ability to design and interpret controlled experiments is an important scientific process skill and a common objective of science standards. Numerous intervention studies have investigated how the control-of-variables-strategy (CVS) can be introduced to students. However, a meta-analysis of 72 intervention studies found that the opportunity to…

The Science Teachers Learning from Lesson Analysis (STeLLA) project is a videobased analysis-of-practice PD program aimed at improving teacher and student learning at the upper elementary level. The PD program developed and utilized two "lenses," a Science Content Storyline Lens and a Student Thinking Lens, to help teachers analyze science…

"Science for All" is a mantra that has guided science education reform and practice for the past 20 years or so. Unfortunately, after 20 years of "Science for All" guided policy, research, professional development, and curricula African Americans continue to participate in the scientific enterprise in numbers that are staggeringly low. What is…

Finnish students' opinions about the frequency of learning activities and communication in the Finnish science classroom, their interest in science and science studies and careers, their sense of self-efficacy, and their beliefs about their own competence as well as their performance in science are analyzed based on PISA 2006 Scientific Literacy…

A Prelaboratory Preparation Period (PPL) was developed to introduce freshmen level students to weekly laboratories. Results (based on data obtained from 233 chemistry students) show that the PPL increased the academic achievement of students enrolled in the introductory chemistry course. (JN)

College biology students attending an audio-tutorial center with high kinetic structure performed significantly better on achievement tests than students in a corresponding low kinetic structure laboratory. Gives numerous other findings concerning measurable aspects of audio-tutorial settings. (MLH)

Determined the effects of questions on the learning of 55 undergraduate education majors from case exhibits associated with a "walk-through" museum exhibit. The case exhibits contained diagrams, some specimens, a large amount of written material, but no questions. Also compared the effects of experimenter generated questions versus…

Describes an aptitude treatment interaction (ATI) hypothesis used to investigate relationships among aptitudes and science instructional treatments in terms of student performance. It is proposed that ATI research work in science education will systematically yield reliable generalizations about how to adapt instruction to individuals with…

Explores the effects of teaching particulate representation of chemistry on the achievement of high school students in terms of gender interaction. Indicates that females who were taught the particulate representation scored as well as males whereas those who were not taught the particulate representation scored significantly lower than males.…

Studied the effectiveness of using a prior knowledge of behavioral objectives in instruction to enhance ninth grade students' achievement in and retention of physical science learning. Concluded that the use of behavioral objectives was effective both in individualized and whole class instruction. (CC)

The selective attention model was used to explain effects of overprompting students (N=170) provided with study questions adjunct to a complex flow diagram describing scientific cyclical schema. Strongly prompting students to answers of questions was less effective than an unprompted question treatment, suggesting that prompting techniques be used…
