This work discusses the use of Darwin's "Tree of Life" as a didactic analogy and metaphor in teaching evolution. It investigates whether biology teachers of pupils from 17 to 18 years old know Darwin's text "Tree of Life". In addition, it examines whether those teachers systematically employ either the analogies present in that…

This article investigates the effectiveness of a statewide 6-month early childhood mental health consultation (ECMHC) model on teachers' emotional support of children and classroom organization. We provide a brief historical and theoretical background of the field of ECMHC, present the logic model for our ECMHC intervention, and discuss the…

The effects of two systematic methods of phonics instruction for children with significant cognitive disability were compared. Fifty-two participants, aged 5-12 years were randomly assigned to one of three treatment groups: (i) a synthetic phonics instruction, (ii) an analogy phonics instruction group, and (iii) a control group. Participants in…

Research on teaching high school mathematics shows that the topic of percentages often causes learning difficulties. This article describes a method of teaching percentages that the authors used in university bridging courses. In this method, the information from a word problem about percentages is presented in a two-way table. Such a table gives…

When two sealed envelopes contain money, one twice as much as the other, a player should be indifferent between them. But when one envelope is opened, one's decision should vary as a function of the observed value and one's subjective probabilities.

This study addressed preschoolers' cognitive flexibility in an inductive task requiring response feedback processing to infer relevant task goals. A total of 63 4- to 6-year-olds were tested on a perceptual matching task in which they needed to switch attention among three colors. A computational model was designed to track down how responses to…

Research on induction of newcomers is primarily focused on individual processes, such as acquisition of knowledge and socialization in order to create a smooth and frictionless entry period. The interest of our research, however, is the processes that happen on the organizational level. We claim that induction potentially triggers both individual…

I tested the effects of the absence and presence of Naming on rate of learning when teacher modeling was part of an instructional procedure. A time-lagged multiple probe design across matched pairs of participants was implemented. Eight elementary aged children with autism, ranging in age from 4 to 7 years old, were selected because they lacked…

Research investigating graduate teaching assistants' (TAs') knowledge of fundamental statistics concepts is sparse at best; yet at many universities, TAs play a substantial role in the teaching of undergraduate statistics courses. This paper provides a framework for characterizing TAs' content knowledge in a sampling context and endeavors to raise…

A recent resurgence in logical-rule theories of categorization has motivated the development of a class of models that predict not only choice probabilities but also categorization response times (RTs; Fific, Little, & Nosofsky, 2010). The new models combine mental-architecture and random-walk approaches within an integrated framework and…

An introductory organic classroom demonstration is discussed where analogies are made between common societal hand contact and covalent bond formation. A handshake signifies creation of a [sigma] bond ("head-on" orbital overlap), whereas the action of praying illustrates "sideways" overlap and generation of a [pi] bond. The nature of orbital and…

In this paper there is a critical overview of the role of analogies as tools for meaning making in science education, their advantages and disadvantages. Two empirical studies on the use of analogies in primary classrooms are discussed and analysed. In the first study, the "string circuit" analogy was used in the teaching of electric circuits with…

This study compared the effectiveness of collaborative group composition and instructional method on reasoning gains and achievement in college biology. Based on initial student reasoning ability (i.e., low, medium, or high), students were assigned to either homogeneous or heterogeneous collaborative groups within either inquiry or didactic…

Developmental studies have provided mixed evidence with regard to the question of whether children consider sample size and sample diversity in their inductive generalizations. Results from four experiments with 105 undergraduates, 105 school-age children (M = 7.2 years), and 105 preschoolers (M = 4.9 years) showed that preschoolers made a higher…

In this article, the authors present an analogy that uses coins and graphical analysis to teach kinetics concepts and resolve pseudo-first-order rate constants related to transition-metal complexes ligand-solvent exchange reactions. They describe an activity that is directed to upper-division undergraduate and graduate students. The activity…
