Effective self-reflection is a key component of excellent teaching. We describe the types of self-reflection identified in tutors' reflective statements following a peer observation of teaching exercise. We used an adapted version of the categories developed by Grushka et al. (2005) to code text from 20 written statements as technical (26% of comments), practical (36% of comments) and critical (33% of comments). Tutors also wrote about the affective aspects of the exercise and the majority of such comments were positive. Most tutors reflected in a holistic way about their teaching, noting the importance of getting the technical aspects right while also being concerned about pedagogical matters and issues beyond the classroom. The exercise was an effective way to prompt tutors to reflect on their teaching and helped tutors articulate and formalise their learning from the peer observation activity.Suggestions for further exploration of the reflective practice of tutors are provided.

The present study examines the impact of first-time introduction of warrants by third party issuers on the trading behaviour of a sample of underlying stocks listed on the Australian Stock Exchange. We investigate the price, liquidity and volatility impact of underlying stocks after warrant issuance and find considerable differences to those found for option listings. Significant negative abnormal returns on both the announcement and listing date of derivative warrants are reported, followed by a negative price drift. Relative trading volume and price volatility of underlying stocks are found to be significantly higher post-warrant listing. Interestingly, we find that warrant holders are unable to realize gains for the majority of trading days when they are alive, consistent with the view that banks trade profitability from their issue.

In this paper we study the bid-ask spread of covered warrants, which are securitized derivatives also referred to as bank-issued options. We find that most of the factors affecting the size of the bid-ask spread for covered warrants are common to those affecting the bid-ask spread of regular options (such as hedging costs and order processing costs). However, we also find two results that are specific to covered warrants. First, competition among warrant issuers does not play an important role in reducing covered warrant bid-ask spread. Second, warrant market makers set the bid-ask spread taking into account the risk of trading with scalpers. We estimate quantile regressions to check whether the relations between the covered warrant bid-ask spread and explanatory variables depend on the size of the spread and to check whether results are robust to outliers. We find that the coefficient associated with hedging costs increases considerably as the size of the bid-ask spread increases, implying that a change in the hedging costs affects more warrants with wide bid-ask spread than warrants with tight bid-ask spread.
