Research concerning the etiology and prevention of substance misuse has led to the development of preventive interventions that are theory-based and effective. One such approach, Life Skills Training (LST), targets key etiologic factors using a conceptual framework derived from social learning theory and problem behavior theory. LST has been…

This quantitative study investigated how well environmental and individual factors predicted college-going behavior for college eligible Latino/as. Three questions were addressed: (a) Is there a relationship between individual agency and college-going behavior after controlling for environmental factors? (b) What is the relationship between the…

The aim of the present study is to determine the influence of concept definitions of cylinder and cone on primary mathematics student teachers' construction of relevant concept images. The study had a relational survey design and the participants were 238 primary mathematics student teachers. Statistical analyses implied the following: mathematics…

In this research, the information about democracy, which social studies prospective teachers have, and interpretation of the information sources are aimed. The research was planned as a survey research methodology and the participants were determined with criterion sampling method. The data were collected through developed open-ended questions…

Overall, nursing training is a stressful process. Especially when second year nursing students are evaluated within the professional socialization theory, they are stated to be affected by these sources of stress more negatively. This research was carried out in order to determine the stress sources of second year nursing students. 15 nursing…

School consultants who rely on direct observation typically conduct observational samples (e.g., 1 30-min observation per day) with the hopes that the sample is representative of performance during the remainder of the day, but the representativeness of these samples is unclear. In the current study, we recorded the problem behavior of 3 referred…

The purpose of this study was to examine the quality of quantitative articles published in the "Journal of Counseling & Development." Quality concerns arose in regard to omissions of psychometric information of instruments, effect sizes, and statistical power. Type VI and II errors were found. Strengths included stated research…

Propensity score estimation plays a fundamental role in propensity score matching for reducing group selection bias in observational data. To increase the accuracy of propensity score estimation, the author developed a bootstrap propensity score. The commonly used propensity score matching methods: nearest neighbor matching, caliper matching, and…

This supplement contains documentation on the explicit and implicit stratification variables included in the PIRLS 2011 data files. The explicit strata are smaller sampling frames, created from the national sampling frames, from which national samples of schools were drawn. The implicit strata are nested within the explicit strata, and were used…

Researchers are strongly encouraged to accompany the results of statistical tests with appropriate estimates of effect size. For 2-group comparisons, a probability-based effect size estimator ("A") has many appealing properties (e.g., it is easy to understand, robust to violations of parametric assumptions, insensitive to outliers). We review…

The introduction of technology into the classroom has revolutionized teaching and learning process. The 21st century learning environment creates exciting learning for students to collaborate and learn at their own pace making them active participants in learning process. The teacher is no-longer a dictator, pouring knowledge into passive learners…

The introduction of Free Primary Education (FPE) policy in 2003 was aimed at enhancing the enrolment of all school going-age children in Kenya indiscriminately. However, significant concerns have been raised by scholars and the public over the low enrolment of children with Special Needs Education (SNE). The main objective of this study was to…

This study explored the effect of self-regulated learning approach on junior secondary school students' achievement in basic science. Quasi-experimental design was used for the study.Two co-educational schools were drawn for the study through simple random sampling technique. One school was assigned to the treatment group while the other was…

Educational researchers commonly use the rule of thumb of "design effect smaller than 2" as the justification of not accounting for the multilevel or clustered structure in their data. The rule, however, has not yet been systematically studied in previous research. In the present study, we generated data from three different models…
