Teachers’ use of their mathematical knowledge for teaching in learning a mathematics learning trajectory

In the past decade, research on learning trajectories has progressed from an agenda for research on student learning to include an agenda for research on teaching. In this paper, we use a design experiment to examine a professional development program created to support teacher learning of one learning trajectory. Using a re-interpretation of Ball and colleagues’ mathematics knowledge for teaching framework, we conducted a retrospective analysis to examine how a purposefully selected sample of three teachers used their knowledge to participate in discussions of the professional learning tasks designed to support teacher learning of the trajectory. Findings indicate that professional learning tasks focusing on pedagogical content knowledge present in learning trajectories also allow for teacher learning of subject matter knowledge; this learning is mediated by teachers’ prior mathematics knowledge for teaching. We conclude with considerations for researchers and professional developers seeking to support teachers in learning about learning trajectories.     

Mobile devices in medicine: a survey of how medical students,residents, and faculty use smartphones and other mobile devices to find information

Objectives:

The research investigated the extent to which students, residents, and faculty members in Canadian medical faculties use mobile devices, such as smartphones (e.g., iPhone, Android, Blackberry) and tablet computers (e.g., iPad), to answer clinical questions and find medical information. The results of this study will inform how health libraries can effectively support mobile technology and collections.

Methods:

An electronic survey was distributed by medical librarians at four Canadian universities to medical students, residents, and faculty members via departmental email discussion lists, personal contacts, and relevant websites. It investigated the types of information sought, facilitators to mobile device use in medical information seeking, barriers to access, support needs, familiarity with institutionally licensed resources, and most frequently used resources.

Results:

The survey of 1,210 respondents indicated widespread use of smartphones and tablets in clinical settings in 4 Canadian universities. Third- and fourth-year undergraduate students (i.e., those in their clinical clerkships) and medical residents, compared to other graduate students and faculty, used their mobile devices more often, used them for a broader range of activities, and purchased more resources for their devices.

Conclusions:

Technological and intellectual barriers do not seem to prevent medical trainees and faculty from regularly using mobile devices for their medical information searches; however, barriers to access and lack of awareness might keep them from using reliable, library-licensed resources.

Implications:

Libraries should focus on providing access to a smaller number of highly used mobile resources instead of a huge collection until library-licensed mobile resources have streamlined authentication processes.     

Use of a mnemonic technique to teach young children foreign language vocabulary

Children 3 to 6 years of age learned simple Spanish vocabulary items using an adaptation of the keyword method of foreign language vocabulary learning. Using this version of the keyword method, the learner remembered a picture of the translation referent of the vocabulary item interacting with the referent of a concrete English word which sounded like part of the foreign word (the keyword). Children who used the keyword method remembered more vocabulary translations than children who were not instructed in keyword method usage.     

Self-efficacy and achievement behaviors

In this article self-efficacy research is reviewed in domains relevant to education. Research addressing cognitive skills, social skills, motor skills, and career choices has shown that self-efficacy is an important construct that helps to explain students' learning and performance of achievement-related behaviors. Research also has identified variables that are associated with educational contexts and that signal to students how well they are achieving or making progress in learning. These task-engagement variables include models/social comparative information, goal setting, attributional and performance feedback, strategy instruction, cognitive processing, and reward contingencies. A suggested future self-efficacy research agenda might include maintenance and generalization of changes in self-efficacy, the identification of additional task-engagement variables, instrument development and validation, integration of efficacy information from diverse sources, developmental influences on self-efficacy, and teachers' sense of efficacy.     

Is Self‐worth Protection Best Regarded as Intentional Self‐handicapping Behaviour or an Outcome of Choking Under Pressure?

Self‐worth protective students characteristically perform poorly when they anticipate that poor performance is likely to reveal low ability, yet perform well in situations that involve little threat to self‐worth. The present study sought a further understanding of this variable pattern of achievement, assessing two possibilities: (1) that the poor performance of students high in self‐worth protection in situations of high evaluative threat is appropriately viewed as self‐handicapping behaviour in the form of strategic withdrawal of effort, and (2) that the poor performance of students high in self‐worth protection is an outcome of anxiety or “choking under pressure”. Participants were 72 undergraduate students, either high or low in self‐worth protection, assigned to one of three performance feedback conditions: humiliating failure, failure allowing face‐saving, and success. They subsequently completed 20 anagrams and 12 remote associates tasks, assessing performance, followed by 16 unicursal tasks during what was believed to be a practice period, providing an assessment of behavioural self‐handicapping in the form of intentional low effort. Students high in self‐worth protection performed poorly on the anagrams and remote associates following humiliating failure. They also reported greater anxiety across experimental conditions and claimed greater anxiety impairment than students low in self‐worth protection. These outcomes provide little support for an interpretation of self‐worth protection as self‐handicapping behaviour, instead supporting an interpretation of self‐worth protection as an outcome of choking under pressure, fuelled by evaluative threat.
