Pre-tests are a non-graded assessment tool used to determine pre-existing subject knowledge. Typically pre-tests are administered prior to a course to determine knowledge baseline, but here they are used to test students prior to topical material coverage throughout the course. While counterintuitive, the pre-tests cover material the student is…

This study assesses the state of the art of the measurement and use of estimated economic value, or "shadow prices," in applying benefit-cost analysis (BCA) to social program evaluation. It reviews 39 effective social programs whose effects have been evaluated using scientifically rigorous methods and documents outcomes affected by the…

As part of a longitudinal investigation of infants at familial risk for attention-deficit hyperactivity disorder (ADHD), mothers and fathers independently completed temperament ratings on their infants. In this paper, we examine the 7-, 12-, and 25-month temperament of 58 boys, 36 of whom were considered at familial risk for ADHD and 22 of whom…

Aim: To compare the occurrence of neurological soft signs (NSS) in children with specific developmental disorders of scholastic skills (SDDSS) and normal children. Methods: 36 cases of SDDSS were compared with 30 control children regarding sociodemographic and clinical variables and neurological soft signs. Results: Children with SDDSS had…

To investigate the influence of an innovative math fluency intervention, 36 middle-school students were randomly assigned to either an experimental (the Detect, Practice, Repair [DPR]) or control condition (reading intervention). After covarying pretest scores, the DPR treatment produced a significantly higher (p = 0.016) adjusted mean (M) math…

The present study analyzed data from the Jyvaskyla Longitudinal Study of Dyslexia to investigate the factors to which mothers of children with and without familial risk for dyslexia attribute the causes of their first-grade children's reading achievement. Mothers' causal attributions were assessed three times during their children's first school…

This study developed an interactive multimedia-based software program for Optics instruction, which was expected to overcome the imperfection of traditional optical labs. The researcher evaluated the effectiveness of the program through an experimental study that compared the learning outcomes of the students who used and did not use the software.…

In this paper the didactically-methodological procedure named the MTE-model of mathematics teaching (Motivation test-Teaching-Examination test) is suggested and recommended when the teacher has subsequent lessons. This model is presented in detail through the processing of a nonstandard theme--the theme of decomposition of planes. Its efficiency…

The given paper presents the results of an empirical study into the efficacy of the Thinking Approach (TA) to language teaching and learning which is aimed at the development of students' inventive thinking skills in the context of foreign language education, namely learning of English. The study was conducted among upper secondary students of two…

This study aimed to investigate the effectiveness of a school-based universal preventive stress management training program for early and middle adolescents in comparison with a no-treatment control group. The study examined the intervention effects of age (early versus middle adolescents) and gender on perceived stress, interpersonal coping, and…

The impact of a yearlong professional development intervention on physical education teachers' psychosocial perceptions was investigated. Experienced mentor teachers (n = 15) were paired with inexperienced protege teachers (n = 15) who helped them learn how to teach a health-related physical education curriculum (i.e., the Exemplary Physical…

This paper presents the results of a quasi-experimental study that brought 3D constraint-based parametric solid modeling technology into the high school mathematics classroom. This study used two intact groups; a control group and an experimental group, to measure the extent to which using a parametric solid modeler during instruction affects…

The effectiveness of the "Tools of the Mind (Tools)" curriculum in improving the education of 3- and 4-year-old children was evaluated by means of a randomized trial. The "Tools" curriculum, based on the work of Vygotsky, focuses on the development of self-regulation at the same time as teaching literacy and mathematics skills…

Few studies have examined predictors of weight regain after significant weight losses. This prospective study examined behavioral and psychological predictors of weight regain in 261 successful weight losers who completed an 18-month trial of weight regain prevention that compared a control condition with self-regulation interventions delivered…

In high-school chemistry the pre-experimental phase of inquiry cycles often remains neglected. According to a procedural model, which is described in the text, this phase begins with an observation that stimulates students' prior factual knowledge, the formulation of a research question for further elaboration (epistemic questions), the…
