Teachers often struggle to implement inquiry-based science teaching. To support them, IndagApp--a 3D educational app that offers curriculum-aligned, inquiry-based lesson plans--was designed. The app is rooted in the inquiry phases recommended in best-practices literature, which arguably align with most international standards. This study describes…

Guided and open inquiry strategies are found to improve students' attitudes toward science. Yet, confirmation and structured inquiry are more often enacted by teachers. The effectiveness of these approaches involving high teacher guidance remains unexplored. Students in six classes (N = 119, M[subscript age] = 11.25 years) were assigned to control…

Alternative pathways to teaching licensure were developed to address teacher shortages. These programs differ widely, making it difficult to generalize the effects. This study compares the impact of two alternative licensure programs on the development of fundamental elements of science teacher preparation and persistence. The fast-track programs…

In this study, we examined 10 expert and 10 novice teachers' noticing of classroom events in China. It was found that both expert and novice teachers, who were selected from two cities in China, highly attended to developing students' mathematics knowledge coherently and developing students' mathematical thinking and ability; they also paid…

This quasi-experimental study investigated how explicit instruction about multiple modes of representation (MMR) impacted grades 7 (n = 61) and 8 (n = 141) students' learning and multimodal use on end-of-unit assessments. Half of each teacher's (n = 3) students received an intervention consisting of explicit instruction on MMR in science…

With inquiry being one of the central tenets of the national and most state standards, it is imperative that we have a solid means to measure the quality of inquiry-based instruction being led in classrooms. Many instruments are available and used for this purpose, but many are either invalid or too global. This study sought to compare two…

The primary purpose of this classroom experiment was to examine the effectiveness of concrete (hands-on) manipulatives as compared with virtual (computer-based) manipulatives on student review of fraction concepts in third grade and introduction of symmetry concepts in fourth grade. A pretest-posttest design was employed with a sample of 91…

This study assessed the influence of using mind maps as a learning tool on eighth graders' science achievement, whether such influence was mediated by students' prior scholastic achievement, and the relationship between students' mind maps and their conceptual understandings. Sixty-two students enrolled in four intact sections of a grade 8 science…

This paper describes a subset of results from a large-scale two-year independent evaluation study conducted with the "Scientists in School" (SiS) outreach program and two large school boards in Ontario, Canada. Specifically, it explores the responses of elementary students (n= 811) from typically underrepresented groups in science…

Determines if grade nine students (N=98) experiencing similar instructional characteristics but participating in either mastery or traditional labs would demonstrate different concept retention levels. A matched pairs design was employed. Results indicate mastery-based instruction fosters an improvement in cognitive learning of students in this…

This study examines the perceptions of teachers, administrators, parents, community members, and high school students about the science learning environment. The participants were active members of a grant project aimed at creating community action teams. Varrella and Burry-Stock's (1997) Beliefs About Learning Environments (BALE) Instrument was…

This study compares the effectiveness of two forms of a knowledge mobilization task on preservice elementary teachers' (n = 65) performance in solving a triangle fraction problem. The study then identifies the source of the successful solutions by linking solutions to earlier activities. One group worked with the triangle fraction task…

Many educational researchers seem to concur with the idea that, among other factors, the teacher's teaching style has some impact on student learning and the perceptions students develop about science learning and the work of scientists. In this study, nine middle grades teachers' teaching styles were assessed using the…
