Design-based methods have recently been developed as a way to analyze randomized controlled trial (RCT) data for designs with a single treatment and control group. This article builds on this framework to develop design-based estimators for evaluations with multiple research groups. Results are provided for a wide range of designs used in…

Design-based methods have recently been developed as a way to analyze data from impact evaluations of interventions, programs, and policies (Freedman, 2008; Lin, 2013; Imbens and Rubin, 2015; Schochet, 2013, 2016; Yang and Tsiatis, 2001). The non-parametric estimators are derived using the building blocks of experimental designs with minimal…

Artificial linguistic systems (ALSs) offer many potential benefits for second language acquisition (SLA) research. Nonetheless, their use in experiments with posttest-only designs can give rise to internal validity problems depending on the baseline that is employed to establish evidence of learning. Researchers in this area often compare…

With this study, it is aimed to review the effects of 8-week core exercises, which are scheduled before the routine exercises, on changes over certain physical and motoric attributes and freestyle swimming performance of female athletes of the youngest age group, which is 9-12. For the study, a group of 12 female licensed swimmers who had a…

Purpose: Graduated compressive stockings (GCS) have been suggested to influence performance by reducing muscle oscillations and improving muscle function and efficiency. However, no study to date has analyzed the influence of GCS on muscle activity during running. The objective of the study was to analyze the influence of GCS on the perception of…

The purpose of this quantitative study was to determine if student perceptions of their advisor and the institution they attended were affected by either the developmental or prescriptive approach that their assigned academic advisor used. A group of academic advisors volunteered at the beginning of the study to be trained in the developmental…

The aim of this study was to investigate the effect of skiing on the biomotoric characteristics of children with evaluating tests of girls between the ages of eight and 14 before and after the season. The experimental group of this study was 15 girls who had just started skiing and the control group of 30 girls. In total, 45 volunteers joined the…

Generating creative ideas in a brainstorm session `is a crucial part of innovation. However, for actual implementation, the most creative ideas must be selected from a pool of ideas. To date, idea selection has remained relatively unexplored and validated instruments to measure idea selection performance are not systematically employed. This study…

The purpose of this study was to determine the overall effectiveness of conceptual change texts (CCTs) on academic achievement and to find out if effectiveness was related to some characteristics of the study. It followed up a Meta-analysis research approach. 42 published and unpublished studies, published between 1995 and 2010, and 42 experiment…

This study has been performed on 44 volunteers all of whom are students in Yüzüncü Yil University and participating in the university's folk dances activities. A twelve week program was carried out.

Infants and young children with autism demonstrate impairments in both initiating and responding to joint attention bids in naturalistic settings. However, little is known…

The purpose of this study is to examine whether motivational music selected by participants has an effect on maximal bench press strength and strength endurance (number of repetitions to failure with a 60% of 1-RM). 26 healthy male students with an average age of 23.92 ± 2.05, average weight of 73.57 ± 4.14 and average height of 178.57 ± 3.65 who…

In this study we examine whether Environmental Education (EE) can increase the discipline-specific environmental knowledge of students in a logistics faculty. We also investigate the degree to which logistics students are willing to attend EE classes. Results show that participation in a short EE course supplied students with higher levels of…
