Adolescent clinical and subclinical depression has a significant negative impact on adolescents well being, school performance and consequently produces maladaptive outcomes in terms of subsequent education and occupational functioning. This research is a part of a larger research project with a focus on clinical and subclinical depression during…

Reporting standards and critical appraisal tools serve as beacons for researchers, reviewers, and research consumers. Parallel to existing guidelines for researchers to report and evaluate group-comparison studies, single-case experimental (SCE) researchers are in need of guidelines for reporting and evaluating SCE studies. A systematic search was…

Multisite trials, in which individuals are randomly assigned to alternative treatment arms within sites, offer an excellent opportunity to estimate the cross-site average effect of treatment assignment (intent to treat or ITT) "and" the amount by which this impact varies across sites. Although both of these statistics are substantively…

The students in working in laboratories in 21st century are preferred to take place as active participants in the experiments coming up with their own designs and projects by developing new ideas and problems rather than implementing the ones told and ordered by others during these experiments. The science teachers that would have the students…

This study revisits case learning's effects on student engagement and assesses student learning as a result of the use of case studies and problem-based learning. The author replicates a previous study that used indirect assessment techniques to get at case learning's impact, and then extends the analysis using a pre- and post-test experimental…

Randomized trials have experienced a marked surge in endorsement and popularity in education research in the past decade. This surge reignited paradigm debates and spurred qualitative critics to accuse these experimental designs of eclipsing qualitative research. This article reviews a current iteration of this debate and examines two randomized…

Despite the potential educational value of nature documentaries, the contribution of such films to environmental education is largely unknown. In the present study, we attempt to delineate the role of nature documentaries to the environmental sensitivity of students when the films are simply introduced to the class. More specifically, the present…

Animal models have been widely used for studying the physiology and pharmacology of psychiatric and neurological diseases. The concepts of face, construct, and predictive validity are used as indicators to estimate the extent to which the animal model mimics the disease. Currently, we used these three concepts to design a theoretical assignment to…

The study was conducted to determine the effectiveness of Information Communication and Technology tools viz DLP (Distance Learning Projector) and Computer/Laptop in comparison with selected instructional media for teaching primary and secondary school pupils. It examined the effect of grade on the performance of the pupils taught with four…

This article discusses the use of propensity scoring in experimental program evaluations to estimate impacts for subgroups defined by program features and participants' program experiences. The authors discuss estimation issues and provide specification tests. They also discuss the use of an overlooked data collection design--obtaining predictions…

This longitudinal case-study aimed at examining whether purposely teaching for the promotion of higher order thinking skills enhances students' critical thinking (CT), within the framework of science education. Within a pre-, post-, and post-post experimental design, high school students, were divided into three research groups. The experimental…

Counseling psychology is a relatively new field that is gaining autonomy and respect. Unfortunately, research efforts in the field may lack an appropriate research design. This paper considers some of the more common types of research design and the associated threats to their validity. An example of each design type is drawn from the counseling…

Background: There is limited research on the FL composition writing of Egyptian experimental secondary students. Purpose: The purpose of the present study is to investigate the effect of the Whole Language Approach on developing the required composition writing skills in English for experimental secondary students. Setting: Salah Salem…

A context in which existing items may provide a convenient source of questions for questionnaires was explored through a case study making use of existing comparison groups. Two programs at Oak Ridge Associated Universities (ORAU), the Science and Engineering Research Semester (SERS) and the Laboratory Graduate Research Participation (Lab Grad)…

The suggestions offered in this paper are based on the experiences of two scientific researchers of how evaluations undertaken in a competitive arena, in which true experimental designs are not viable, can be designed in such a way that meaningful comparative data can be examined. Case studies of the Science and Engineering Research Semester and…
