The educational goals and objectives provide a reference for curriculum designers, teachers, and educators, and they are required for evaluation or accreditation processes. This article presents a systematic method to state the learning objectives and analyze the consistency of a secondary school science program developed in Spain. The method is…

We evaluated the statistical power of single-indicator latent growth curve models (LGCMs) to detect correlated change between two variables (covariance of slopes) as a function of sample size, number of longitudinal measurement occasions, and reliability (measurement error variance). Power approximations following the method of Satorra and Saris…

Responses to the 1999 Youth Risk Behavior Survey including suicide ideation, attempt, medically treated attempt, and six problem behaviors were analyzed. Youth across the spectrum ideated. Overwhelmingly, the 17% of youth with more than three problem behaviors were the youth who acted; they accounted for 60% of medically treated suicidal acts.…

The Preferred Items and Experiences Questionnaire (PIEQ) is a new instrument to assess reinforcer preferences in adolescents and adults. Research was conducted with college and high school students to develop the PIEQ, to examine its reliability with test-retest and internal consistency methods, and to test its validity. This research provides…

Pedagogical agents are gaining acceptance as effective learning tools (Baylor & Ryu, 2003; Moreno, Mayer, Spires & Lester 2001; Moreno, 2004). The increase in the use of agents highlights the need for standardized measurements for evaluating user performance in these environments. While learning gains are a primary variable of interest in such…

This paper describes students' solutions to a commonly taught and not commonly taught inequality. The findings showed students' difficulties. Participants implicitly and explicitly exhibited two intuitive beliefs: inequalities must result in inequalities and solving inequalities and equations are the same process. Following the analysis of…

The current preference for alternative assessment has been partly stimulated by recent evidence on learning which points to the importance of students' active engagement in the learning process. While alternative assessment may well fulfill the aims of formative assessment, its value in the summative assessment required in higher education is more…

Psychological research has repeatedly demonstrated two seemingly irreconcilable human tendencies. People are motivated towards internal consistency, or acting in accordance with stable, self-generated preferences. Simultaneously though, people demonstrate considerable variation in the content of their preferences, often induced by subtle external…

This paper uses narrative and reflective methodologies to examine pedagogical practices that enable the production of meaningful relationships. I suggest that the term "fields of influence" encapsulates practices that enable some people to influence relationships with others. The narrative invites readers to consider how the embodied qualities…

In 1993, the language section of the Swedish Migration Board initiated the production of documents they called "language analyses" to aid in the processing of asylum seekers. Today, 11 years later, 2 privately owned companies in Stockholm produce these documents. These companies have produced language analyses not only for the Swedish…

The reliability of Attention-Deficit/Hyperactivity Disorder (ADHD) rating scales in children with mental retardation was assessed. Parents, teachers, and teaching assistants completed ADHD rating scales on 48 children aged 5-12 diagnosed with mental retardation. Measures included the Child Behavior Checklist (CBCL), Conners Rating Scales, the…

Current accountability policy that bases assessment on validity and reliability criteria in the positivist research tradition is counterproductive to serving adult learners and their communities. In this article, we outline a framework for accountability that allows for the emergence and demonstration of the full range of program outcomes and…

First an overview is given about the actual national and international situation concerning standardized testing. Then two major reasons are presented why accountability systems based on standardized testing have become so widespread: (a) the missing validity and reliability of teachers' assessment of students' achievement, and (b) the important…

Analysis of continuous variables sometimes proceeds by selecting individuals on the basis of extreme scores of a sample distribution and submitting only those extreme scores to further analysis. This sampling method is known as the extreme groups approach (EGA). EGA is often used to achieve greater statistical power in subsequent hypothesis tests.…

Hierarchical agglomerative cluster analysis (HACA) may yield different solutions under permutations of the input order of the data. This instability is caused by ties, either in the initial proximity matrix or arising during agglomeration. The authors recommend to repeat the analysis on a large number of random permutations of the rows and columns…
