It is proposed that the education system should be evaluated by relying on views of branch teachers about changes in the Turkish Education System by discussing these effects from a scientific background. In this research, a qualitative approach was adopted so that the issue can be examined thoroughly. In this research, the phenomenological pattern…

Context provides meaning for data analysis and the evaluation of evidence but may be distracting to students. This research explores the role of context in students' reasoning about sampling: specifically, the relationship between the strength of students' opinions about a topic, which provides the context for a study, and their ability to judge…

Special educators are required to use evidence-based academic and behavioral interventions in their classrooms (U.S. Department of Education, 2010). No rigorous and comprehensive database currently exists to support educators. Within the field of special education, single-subject research is the primary research methodology (Horner, Carr, Halle,…

In some instances, intentionally or not, study designs are such that there is clustering in one group but not in the other. This paper describes methods for computing effect size estimates and their variances when there is clustering in only one group and the analysis has not taken that clustering into account. The authors provide the effect size…

Recent research on the design of social experiments has highlighted the effects of different design choices on research findings. Since experiments rarely collect their samples using random selection, in order to address these external validity problems and design choices, recent research has focused on two areas. The first area is on methods for…

We explore the use of instrumental variables (IV) analysis with a multi-site randomized trial to estimate the effect of a mediating variable on an outcome in cases where it can be assumed that the observed mediator is the only mechanism linking treatment assignment to outcomes, as assumption known in the instrumental variables literature as the…

People must often engage in sequential sampling in order to make predictions about the relative quantities of two options. We investigated how directional motives influence sampling selections and resulting predictions in such cases. We used a paradigm in which participants had limited time to sample items and make predictions about which side of…

The way an animal moves from place to place can inform us about its life and environment. In this lesson, students examine the travel patterns of juvenile flatfishes in an estuary. The process of sampling bottom-dwelling fishes is explained, and data from a university-based marine science laboratory are evaluated. Students compare the distance…

The research was conducted to look into learner diversity in inclusive classrooms focusing on language of instruction, gender and disability issues, and their implications for education practices. A qualitative research approach was used to obtain data addressing the research problem from two inclusive secondary schools in Dar es Salaam region,…

This study examined lecturers' perception of research activities for knowledge production in universities in Cross River State, Nigeria. Two hypotheses were isolated to give direction to this investigation. 240 university lecturers were sampled from a population of 1,868 from the two universities in Cross River State, using stratified random…

This article describes the process by which we created a recruitment protocol for engaging adolescent sexual assault victims in a qualitative evaluation study. Working in collaboration with forensic nurses, rape victim advocates, adolescent rape survivors, and our institutional review board (IRB), we created a prospective recruitment method…
