An Examination of Text Complexity as Characterized by Readability and Cohesion

To better understand dimensions of text complexity and their effect on the comprehension of adolescents, 103 high school seniors were randomly assigned to 4 groups. Each group read versions of the same 2 informational passages and answered comprehension test items targeting factual recall and inferences of causal content. Group A passages had a challenging readability level and high cohesion; Group B passages had an easier readability and low cohesion; Group C passages had a challenging readability level and low cohesion; and Group D passages had an easier readability and high cohesion. Students in Group D significantly outperformed students in Group C (g = 0.78). Although the effect sizes of comparisons among all groups ranged from g = 0.13 to 0.73, no other comparisons were statistically significant. Results indicate that adolescents’ reading comprehension is dually influenced by a text's readability and cohesion. Implications for matching readers to instructional text are discussed.     

A pragmatic approach to courseware development in WIMP environments

Courseware development often involves a great deal of effort. One approach to minimising effort while maintaining flexibility is illustrated, using a tutoring system as an example. The system comprises two parts: a 'shell' which contains facilities useful for many different subjects, and an interpreter which generates questions which are subject specific.     

College Students’ Reasons for Depression Nondisclosure in Primary Care

Unwillingness to share depression experiences with primary care physicians contributes to the undertreatment of depression. This project examined college students’ reasons for depression nondisclosure to primary care providers (PCPs). Undergraduate participants read a vignette describing someone with depression and completed measures of disclosure barriers. Analyses indicated 26% of respondents would NOT disclose depression symptoms to PCPs. Reasons for nondisclosure included difficulty initiating the depression conversation, medication aversion, and fear of referral to a psychologist. Also, anger toward the vignette character varied with disclosure willingness, suggesting that nondisclosers feel more stigma than disclosers and are less likely to engage in psychotherapy. Because engagement in pharmacological and/or psychotherapeutic treatment requires identification of depression in healthcare settings, increased understanding of disclosure barriers could increase students’ access to depression treatment.     

Regarding uncertainty in teachers and teaching

The literature on teacher uncertainty suggests that it is a significant and perhaps inherent feature of teaching. Yet there is disagreement about the effects of these uncertainties on teachers as well as about the ways that teachers should regard them. Recognition of uncertainties can be viewed alternatively as a liability or an asset to effective teaching. Findings from the literature on uncertainties in teaching are summarized and analyzed, including explanations in the research about what accounts for and contributes to uncertainties. Recommendations for research and professional development are provided.     

Play as the Leading Activity of the Preschool Period: Insights from Vygotsky, Leont'ev, and Bakhtin

Cultural-historical psychology identifies play as the leading activity in preschool development. Vygotsky's (1967, 1978) seminal work outlined two categories of leading influences: play makes a foundational contribution to the development of semiotic mediation, and it involves active appropriation of social roles and rules and other integral aspects of social organization. Leont'ev's (1981) concept of appropriation and Bakhtin's (1981) concepts of heteroglossia and ideological becoming are used to elaborate and extend Vygotsky's original work, particularly with regard to creativity in preschool play. The paper concludes with a consideration of the pedagogical implications of the cultural-historical view on play, including the use of play to cultivate understanding of the arbitrary nature of signs and the appropriation of the social roles and organizational patterns of society.

School psychology graduate education retention research characteristics: Implications for diversity initiatives in the profession

Lack of racial and ethnic diversity in the school psychology workforce has been a concern since the profession's inception. One solution is to graduate more racially and ethnically diverse individuals from school psychology programs. This structured review explored the characteristics of studies published from 1994 to 2017 that investigated graduate student retention and school psychology. An electronic search that included specified databases, subject terms, and study inclusion criteria along with a manual search of 10 school psychology journals yielded two published, peer‐reviewed studies focused primarily on graduate student retention and school psychology over the 23‐year span. Two researchers coded the studies using a rigorous coding process with high inter‐rater reliability. Findings suggest that mostly Black and White individuals served as participants, undergraduate students represented the largest group sampled, and key school psychology stakeholders’ views were missing. Additionally, programs interested in retaining racially and ethnically diverse students should have a commitment to multicultural issues, expose students to diverse professional networks and mentorship, and cultivate an inclusive program environment. Implications point to a need for more studies focused on school psychology graduate student retention in general and in specific relation to retaining racial and ethnic minoritized students.     

Analyzing and Selecting Instructional Strategies and Tactics

“Formulation of instructional strategy to match subject matter and learner requirements” is an integral part of most instructional design models (Andrews & Goodson, 1980, p.5). Yet the meaning and purpose of instructional strategies in these design models vary considerably. An instructional strategy in traditional design models usually refers to the selection of instructional delivery vehicles (e.g., lecture, demonstration, computer-assisted instruction) and support activities (e.g., practice exercises, tutoring) (cf. Tracey, Flynn, <& Legere, 1970). Contrast those conceptions with the many instructional strategies described in elaboration theory (Reigeluth & Stein, 1983), such as sub-sumptive sequencing, internally consistent orienting structures, synthesizers, summarizers, and cognitive strategy activators. What is obvious from these disparate conceptions is that instructional designers do not share a consistent definition of instructional strategies. Many of the activities that are referred to as instructional strategies are not in fact strategies, but rather are presentation vehicles. In this article, we first define instructional strategies and tactics in the context of an iterative design model. Instructional strategies are then distinguished from instructional tactics, which are the implementation of strategies. We then list the range of instructional strategies and tactics that implement them. Finally, we provide a decision tree for assisting designers to select appropriate instructional tactics.
