Early experiences with theoretical thinking and generalization in measurement are hypothesized to develop constructs we name here as logical reasoning and preparedness for algebra. Based on work of V. V. Davydov (1975), the Measure Up (MU) elementary grades experimental mathematics curriculum uses quantities of area, length, volume, and mass to…

This quasi-experimental study investigated the effects on 558 grades five and six students of three different teaching conditions: the "classical" model of conceptual change (for which cognitive conflict is considered as a precondition to the transformation of knowledge), the "prevalence" model of conceptual change (in which…

This study examined the effectiveness of two instructional mind-mapping approaches to stimulate fifth and sixth graders' graphical summarization skills. Thirty-five fifth- and sixth-grade teachers and 644 students from 17 different elementary schools participated. A randomized quasi-experimental repeated-measures design was set up with two…

To overcome barriers to improved outcomes, we undertook an intervention to teach schoolchildren how to detect a stroke and call emergency medical services (EMS). We obtained permission from parents and guardians to use an 8-min puppet show to instruct the fourth, fifth, and sixth graders about stroke detection, symptomatology, and calling EMS. A…

The authors explore the effects of student tutoring as an approach to provide support on self-regulated learning (SRL) to fifth- and sixth-grade students with a low socioeconomic or immigrant background. In total, 401 Flemish (Belgium) students participated. A quasi-experimental study with pretest, posttest, and retention test control group design…

This article describes the effects of an analysis-of-practice professional development (PD) program on elementary school students' (Grades 4-6) science outcomes. The study design was a cluster-randomized trial with an analysis sample of 77 schools, 144 teachers and 2,823 students. Forty-two schools were randomly assigned to treatment, (88.5 hours)…

The purpose of this study was to examine the effect of an information and communications technology (ICT)-based individualised music education programme on primary students' musical competence. A 2 × 3 aptitude treatment interaction factorial design was used to assess the impact of the programme as a function of students' musical aptitude (MA)…

Introduction: Coexistence in schools inevitably implies conflicts among peers, which can have a negative impact in both the students' well-being and their academic achievement. In this sense, the main objective of the present article is to introduce and describe the evaluation of the Training Program in Emotional Management Happy 8-12. This…

In 2010 1.1 million pupils took private lessons in Germany, with 25% of all German children by the age of 17 having attended paid private lessons at some point in their school career (Klemm & Klemm, 2010). The high demand for support for learning curricular content led us to consider an integrated solution that speeds up both the design of…

The purpose of this study was to explore the effectiveness of the creative inquiry-based science teaching on students' creative science thinking and science inquiry performance. A quasi-experimental design consisting one experimental group (N = 20) and one comparison group (N = 24) with pretest and post-test was conducted. The framework of the…

The new science education reform documents call for integration of engineering into K-12 science classes. Engineering design and practices are new to most science teachers, meaning that implementing effective engineering instruction is likely to be challenging. This quasi-experimental study explored the influence of teacher-developed, engineering…

"Cooperative Integrated Reading and Composition"[R] ("CIRC"[R]) is a reading and writing program for students in grades 2-6. It has three principal elements: story-related activities, direct instruction in reading comprehension, and integrated language arts/writing. Daily lessons provide students with an opportunity to practice…

The purpose of this paper is to provide findings from a study into a school peer mentoring program which matched children aged between 9 and 12?years of age who were bullied or at-risk of being bullied with older student mentors. In total, 372 mentees as well as a comparison group of 1,249 young people from 22 English schools completed a…

City Year is a learning organization committed to the rigorous evaluation of its "Whole School Whole Child" model, which trains and deploys teams of AmeriCorps members to low-performing, urban schools to empower more students to reach their full potential. A third-party study by Policy Studies Associates (PSA) examined the impact of…

This article reports on a mixed methods evaluation of an indoor garden-based learning curriculum for 5th and 6th graders which incorporated aquaponics and hydroponics technologies. This study provides a better understanding of the extent to which indoor gardening technologies can be used within the formal curriculum as an effective teaching tool.…
