This study examines the influence of laboratory instruction that engages students in a wide range of the practices of science on Turkish high-school students' chemistry learning. In this mixed methods study, student learning in two different laboratory settings was compared, one that featured an instruction that engaged students in a wide range of…

Contemporary culture is mainly a culture of image. We get our information seeing. Examination of images is free, while reading is impelled by the necessity of browsing the whole text. The image seems more appropriate than the text when trying to communicate easy and quickly. The speech calls for articulated language, expressed through a symbolic…

Scientific visualisations such as computer-based animations and simulations are increasingly a feature of high school Science instruction. Visualisations are adopted enthusiastically by teachers and embraced by students, and there is good evidence that they are popular and well received. There is limited evidence, however, of how effective they…

Our study capitalized on a unique natural experiment rather than a researcher-designed, randomized experiment whereby, thanks to the Australian Government's Digital Education Revolution, half of grade 9 students in 2008 received laptops and half did not. Consequently in late 2011, when these students sat for their grade 12 external examinations…

Multimodal texts involve the presence, absence, and co-occurrence of alphabetic text with visual, audio, tactile, gestural, and spatial representations. This article explores how teachers' evaluation of students' multimodal work can be understood in terms of cognition and culture. When teachers apply a paradigm of assessment rooted in print-based…

Teachers' subject knowledge is recognized as an essential component of effective teaching. In the foreign language context, teachers' subject knowledge includes language proficiency. In New Zealand high schools, foreign languages (e.g. Chinese, French, German, Japanese and Spanish) have recently been offered to learners earlier in their schooling,…

This study explored mathematics teachers' instructional practices in the context of high-stakes testing. Data were obtained from a survey instrument given to a stratified sample of Mississippi and Tennessee teachers who teach the same content tested on their state's high school graduation examination. An analysis showed teachers using a balance of…

This paper presents initial results from a survey of project based learning conducted across a dozen strata of high schools including several major reform networks. This approach to instruction appears to be central to progressive reforms in small high schools. We found relationships to reforms such as teaching across the curriculum, student…
