Objectives: While sleep research in athletes is extensive, no research has investigated sleep in sports officials during a competitive season. This study explored the (a) self-reported quantity and quality of sleep obtained by sports officials according to the time of competition (day or evening) and (b) impact of reduced sleep on perceived…

The use of recorded lecture videos (RLVs) in mathematics instruction continues to advance. Prior research at the post-secondary level has indicated a tendency for RLV use in mathematics to be negatively correlated with academic performance, although it is unclear whether this is because regular users are generally weaker mathematics students…

This study investigated the design and delivery of MOOCs to facilitate student self-monitoring for self-directed learning (SDL) using mixed methods. The data sources of this study included an online survey with 198 complete respondents, semistructured interviews with 22 MOOC instructors, and document analysis of 22 MOOCs. Study results indicated…

In an experiment, secondary students from Australia and Malaysia (n = 130) were randomly assigned to one of three approaches (equation, unitary, unitary-pictorial) to learn how to solve challenging percentage-change problems. In line with the differential types of cognitive load associated with the three approaches, the unitary-approach group…

Although the psychological literature has demonstrated that spatial reasoning and mathematics performance are correlated, there is scant research on these relationships in the middle years. The current study examined the commonalities and differences in students' performance on instruments that measured three spatial reasoning constructs and two…

Two approaches to the process of guided discovery learning are compared for their impacts on concept understanding. One, referred to as design, emphasizes invention and draws on the simulation literature. The other, referred to as case analysis, focuses on discovery and draws on the case-based reasoning literature. Following a lecture on four…

Self-talk has been recognised as an important tool used by children to regulate their thinking and behaviour. Existing studies typically characterise children's self-talk according to broad categories that do not allow for investigation of self-regulatory aspects of children's internalised self-talk. The findings reported in this paper are based…

In view of the minimal attention pronunciation teacher preparation has received in second language (L2) teacher education, this study examined the cognition (i.e. beliefs, thoughts, attitudes and knowledge) development of 15 student teachers during a postgraduate subject on pronunciation pedagogy offered at an Australian tertiary institution.…

Outlines problems students have with understanding the abstract concept of chemical bonding as revealed in previous research. Describes the development of a two-tier multiple-choice diagnostic instrument for assessing alternative conceptions about chemical bonding held by 14-16 year olds. Discusses the instrument and its findings for a group of…

Reports a study to compare the performance of Australian university students on chemistry questions delivered in two different formats: multiple choice and grid. Concluded that students encounter more difficulties with questions presented in the grid format and that grid questions demand a deeper understanding of the topic. (MDH)

Based on the premise that multiple choice tests can be used as diagnostic tools for teachers in identifying and remedying student misconceptions, this study focused on the development of an instrument for diagnosing secondary students' understanding of photosynthesis and respiration. Information is presented on: (1) procedures of development of…
