Examining barriers in technology-enhanced problem-based learning: Using a performance support systems approach

This study focused on the barriers that middle school teachers faced when implementing technology-enhanced problem-based learning (PBL) in their classrooms. Using a human performance-based model, we interviewed teachers, administrators, university faculty and technical support staff to determine the perceived importance of multiple barriers to the implementation of technology-enhanced PBL. Twenty-one teachers, two school administrators and a project manager, two faculty members, and two technical support staff participated in the study. Interview data were supported by surveys, classroom observations and researchers' reflective journals. Results suggested that lack of a clear, shared vision was the primary barrier. Additional barriers included lack of knowledge and skills, unclear expectations and insufficient feedback. Recommendations to support teachers' efforts to integrate technology-enhanced problem-based learning are presented.     

Perceived Utility of Methods and Instructional Strategies Used in Online and Face-to-face Teaching Environments

The purposes of this study were to compare the instructional methods and strategies identified as useful in online teaching environments with those used in a face-to-face teaching environment, to investigate relationships between the perceived usefulness of instructional strategies and methods used by higher education faculty in both teaching environments, and to identify instructional methods transferred from an online to a face-to-face teaching environment. The following instructional methods were found to have a significant relationship with the instructional environment: student collaborative projects, student-to-student electronic discussions, lecture (direct instruction), questioning and feedback to students, and e-mail communication with the instructor.

Resistance to interference in complex negative patterning

Resistance to interference was examined in rats that received a complex negative patterning discrimination in which XA and XB were followed by food reinforcement and XAB was not. Retention of the discrimination was evident after separate reinforcement of both A and B (Experiment 3), but not after reinforcement of either AB (Experiments 1 and 3) or XAB (Experiments 2 and 3). These data suggest that complex negative patterning discriminations are acquired configurally and that the relative similarity of the original discrimination and subsequent interference trials dictates the final degree of retention observed.     

Comparing face-to-face and asynchronous online communication as mechanisms for critical reflective dialogue

Two mechanisms for engaging in critical reflective dialogue are discussed and compared: face-to-face meetings and asynchronous online discussion. The context is an umbrella action research project, with over 20 participants, which aimed to improve practices in online teaching and contribute to the development of graduate attributes. The article compares discussion using the two modes (face-to-face and online) of the nature of and development of problem-solving and other graduate attributes. Face-to-face discussion was wide ranging and quite loosely structured, so divergent aspects of a topic were uncovered. The asynchronous nature of online discussion, however, permitted topics to be explored more thoroughly. The two modes worked well in conjunction with one another, if aspects of face-to-face discussion topics were posted online as discussion threads. The asynchronous online discussions then allowed each thread to be explored in depth, so that collective understanding of a given topic could be enhanced.

The evolution of an effective pedagogy for teachers using the interactive whiteboard in mathematics and modern languages: an empirical analysis from the secondary sector

There has been considerable investment in the use of interactive whiteboard technology in schools in the UK. There is evidence that whilst teachers understand such technology, many do not understand the nature and implications of interactive learning. Observation and analysis of 50 video‐recorded lessons taught by ‘successful’ teachers drawn from mathematics and modern foreign language departments in secondary schools led to the classification of three types of practice representing a spectrum of increasing interactivity. The nature of this good practice was analysed together with criteria for assessing the changes being wrought by technology in approaches to learning and teaching. The investigation concluded that the use of new technology alone cannot lead to enhanced learning. Teachers also need training to develop awareness of the relationship between approaches to interactive learning and conceptual and cognitive development in subject areas.     

Task of the teaching life: Self through bakhtinian dialogue and ideological engagement

This article describes Mikhail Bakhtin’s 20^th century work on dialogue as it may serve one engaged in the teaching as a vocation and existential pursuit rather than as a job or profession. Dialogue, as theorized by Bakhtin, within the pedagogical real, potentially becomes a mod of being through which the individual engages in the project of selfhood, a task basic to the human enterprise. For Bakhtin, dialogue was in part a structure within and through which we come to consciousness and give flesh and meaning to our existence. According to Bakhtin, the structure of self is dialogical and unfinalizable, meaning that each individual comes to consciousness through dialogue with some other. From a Bakhtinian perspective, the, selfhood as a dialogical formation constitutes a fundamental relation by which we much participate without end, making dialogue an unavoidable social activity immersed in language.     

Reward pretraining and discrimination learning set

Pigtailed monkeys were trained on discrimination problems involving objects that had been previously paired with reward, previously paired with nonreward, or objects not associated with any pretraining. In two separate studies, no differences on these various problem formats were observed, but performance improved considerably with practice. These results are contrary to the theories for learning set formation of Spence and Medin.
