Chimpanzees ("Pan troglodytes") and bonobos ("Pan paniscus") (Study 1) and 18- and 24-month-old human children (Study 2) participated in a novel communicative task. A human experimenter (E) hid food or a toy in one of two opaque containers before gesturing towards the reward's location in one of two ways. In the Informing condition, she attempted…

This study investigated whether a word-learning method in which learners infer the meaning of unknown words from the context, subsequently verify the meaning with the aid of a word list, and finally memorize the meaning ("meaning-inferred method") leads to better retention than one in which the meaning of unknown words is given in the form of a…

This article explores the uses of a simulation model (the two bucket story)--implemented by a stand-alone computer program, or an Excel workbook (both on the web)--that can be used for deriving bootstrap confidence intervals, and simulating various probability distributions. The strengths of the model are its generality, the fact that it provides…

Effective coaching is a mixture of pedagogy and principles of sciences, e.g., motor skill acquisition, sociology, and physiology, often referred to as the science of coaching. Instinctive or intuitive coaching has often been incorrectly viewed as the art of coaching. More important should be how coaches develop knowledge, how they access that…

The Profession of Psychology Scale (Rosenthal, McKnight & Price, 2001) was used to investigate whether taking more psychology courses results in a more accurate understanding of what is required to become a psychologist. Data indicate that though misconceptions exist in both Naive students (those who had not completed any psychology courses) and…

The narrative concepts of the implied author and implied reader elucidate how business texts represent writers and readers. It is important, though, to distinguish carefully between writers' "implications" and readers' "inferences." Instructors should contrast implied versus inferred writers and readers, provide multiple ways to comprehend these…

Purpose: This commentary responds to Justice's article on response to intervention (RTI) and evidence-based practice (EBP) for reading instruction. The educational changes brought about by RTI and EBP provide an opportunity as well as a challenge for speech-language pathologists (SLPs) to make fundamental changes in service delivery. Method: In…

Ernst Mach is most closely associated with a positivism that demanded a language of close contact with reality. Mach linked this view with the tradition of the quest for an ideal language in which meaning is a property of a word. Logical positivism and the S-R psychology of the early B. F. Skinner also participated in this ideal-language…

Research Findings: This study analyzed the school readiness beliefs of parents of 452 children from public pre-kindergarten and the relations of these beliefs to socioeconomic status and children's readiness skills. Parents conceived readiness largely in terms of the ability to name objects, letters, or numbers, but few included inferential…

American educational leaders seek to educate children (regardless of race, class, or economic status) to become productive citizens. In order for our country to compete with other countries where students are well educated and highly motivated, we need to ensure that our educational system is equipped with the technology and tools that would allow…

The use of standards-based classroom assessments to test English learners' language proficiency is increasingly prevalent in the United States and many other countries. In a large urban school district in California, for example, a classroom assessment is used to make high-stakes decisions about English learners' progress from one level to the…

This study provided 5 weeks of direct strategy instruction about narrative elements and relations in 4 first-grade classrooms (n = 83), all with materials that made minimal decoding demands on children's reading. Two comparison classrooms (n = 40) received comparable instruction on language development and poetry. A battery of assessments given at…

This paper defines Bayesian network models and examines their applications to IRT-based cognitive diagnostic modeling. These models are especially suited to building inference engines designed to be synchronous with the finer grained student models that arise in skills diagnostic assessment. Aspects of the theory and use of Bayesian network models…

The accuracy of achievement test score inferences largely depends on the sensitivity of scores to instruction focused on tested objectives. Sensitivity requirements are particularly challenging for standards-based assessments because a variety of plausible instructional differences across classrooms must be detected. For this study, we developed a…

Purpose: This study examined the association between cognitive functioning and completion of a durable power of attorney for health care. Design and Methods: Participants were from the Second Longitudinal Study on Aging (LSOA II), a nationally representative sample of community-dwelling persons who were at least 70 years of age at the time of…
