Best practice guidelines for conducting investigative interviews of children emphasise the importance of obtaining free narrative accounts with the use of open-ended questions. However, research indicates that most investigative interviewers underutilise open-ended questions, even following intensive training in their use. The aim of the current study was to explore investigative interviewers' perceptions of their difficulty in asking open-ended questions. During a training course on how to use open-ended questions, eight child abuse investigators were individually interviewed about why they had asked specific questions in a 10-minute mock interview conducted immediately earlier with a school child. Overall, three reasons were identified. These related to: 1. the specificity of the information required from children; 2. the unfamiliar nature of the open-ended discourse style; and 3. the complex distinction between open-ended versus specific questions. Each of these themes is discussed, along with the implications for trainers and researchers in child investigative interviewing.

In addition to making reference to best practices, already known, concerning the conduct of interviews with child victims of sexual abuse, the author describes some of the questions of development that must be made and the four benefits of free narrative. Despite the qualities of this type of approach, surveys show that professionals do not get the research, as a rule, free of narrative descriptions by children and that interviews tend to contain the short answer questions, with few breaks and an excessive number of closed questions and trick.According to trainers, experts in this field, there should be greater recognition of the interview as a forensic specialist skills and promote themselves to more effective supervision and monitoring of the forensic interview at work.

This discussion has evolved from ideas in Peter Sullivan and Pat Lilburn's Open-Ended Maths Activities; Using 'Good' Questions to Enhance Learning (1997). This is a compilation of open-ended questions, and methods for generating open-ended questions, along with a brief rationale for using such questions. This classroom-oriented teaching resource developed from earlier research and teaching development work by Peter Sullivan and David Clarke, and others. Two methods are offered for constructing a 'good question'.

Prior research has highlighted the considerable difficulties investigative interviewers have in adhering to open-ended questions in child abuse interviews. Although improvements in interviewing can be achieved by providing training that incorporates multiple practice opportunities and feedback, currently little is known about the way in which these elements are best administered. The current study extends debate and research on this issue by examining the perceptions of 15 trainee interviewers (police as well as social workers) regarding the relative value of various practical training exercises experienced in a recent training program. The findings indicated that although practice in interviewing was deemed essential, not all tasks were perceived to be equally beneficial. The two most favoured exercises were (a) simulated interviews involving trained actors playing the role of the child, and (b) self-evaluation of a transcribed interview using an objective coding protocol. A summary of the participants' perceptions is provided along with a discussion of the implications for trainers and researchers.

Best-practice guidelines in the area of investigative interviewing of children specify the importance of using open-ended questions. However, use of open-ended questions per se does not maximise interview outcome; open-ended questions can vary markedly in quality. The aim of this study was to identify the nature of investigative interviewers' limitations when using open-ended questions, and to compare how representative these limitations are in three distinct interview paradigms. These interview paradigms include: (a) interviews in which trained actors played the role of a 5-6-year-old child; (b) interviews where 5-6-year-old children recalled an innocuous event that was staged in their school; and (c) actual field interviews where child witnesses aged 5 to 7 years recalled an abusive event. Overall, several common problems that would restrict children's opportunity to provide elaborate and accurate narrative accounts of events were identified and described. Our identification of these problems (using a dichotomous rating scale) was found to be consistent with an independent expert, and their presence was not limited to those interviewers who used a low frequency of open-ended questions. The implications of the findings for researchers and trainers in the area of investigative interviewing of children are discussed.

This study examines preservice elementary teachers' reported experiences of posing open-ended mathematics problems. Responses of 33 students in a mathematics teacher education course were analysed for the strategies participants used, what they learned and the challenges encountered from an opportunity to collect digital images and pose open-ended problems related to those images. Results indicate that preservice teachers reported a shift in the ways they viewed mathematics and how it might be taught. The school curriculum both constrained and provided possibilities for preservice teachers in noticing mathematics beyond the textbook and mathematics classroom. This study adds to our understanding of teaching as a learning practice and the art of posing mathematical problems as a significant aspect of that practice.

Purpose : The current study examined whether several factors related to the job and demographic profile of police officers are associated with adherence to best-practice guidelines when interviewing children.

Method : One hundred and seventy-eight police officers completed a standardized (simulated) interview regarding an allegation of abuse by a 5-year-old child. Immediately prior to this interview, details were obtained from the officers' regarding their job status, gender, interview experience, the timing and nature of prior training/supervision, and experience outside the policing profession with young children.

Results : The results showed that timing of training was the only factor that related to interview performance. The proportion of open-ended questions among participants who completed their interviewer training course less than 1 month prior to the simulated interview was better than those who completed the training earlier. Interestingly, the performance of the latter group was identical to that of a group of participants who had not yet received any formal interview training. The implications of the findings are discussed, along with directions for future research.

This paper describes preservice teachers' reported experience of problem posing based on self-selected original digital images. The 176 participants from Australia and Canada designed open-ended problems as part of their mathematics education course. Their 444 problems and accompanying photos have been analysed lo explore the types of problems posed and the focus of the mathematical connections. Findings indicate that preservice teachers are challenged when posing open-ended problems however, this process enables them to develop strategies for problem posing and to become more critically aware of the mathematical potential within their environment.

This thesis represents one of the first research papers to examine individual factors and their association with best-practice investigative interviewing. Findings indicate that adherence to open-ended questioning (arguably one of the most important skills in child abuse interviewing) is largely the by-product of good training rather than personal attributes or job experience per se. maximising interviewer performance is crucial if the quality of evidence obtained from child witnesses is to improve on a global level.

We present three studies examining the role of prior job experience in interviewing and interviewers’ ability to learn open-ended questions during a training program. We predicted a negative relationship such that more experienced interviewers would perform worse after training than less experienced interviewers, and that (irrespective of baseline performance) the more experienced interviewers would improve the least during training. These predictions were made for two reasons. First, specific questions are commonly used in the workplace (i.e. open-ended questioning constitutes new learning). Second, experience in the use of specific questions potentially interferes with newly learned open-ended questions. Overall, our predictions were supported across different participant samples (including police officers specialized in child abuse investigation and social workers from the child protection area), time delays, and modes of training. The results highlight the need for investment in ongoing investigative interviewing training commencing early during professionals’ careers, prior to the establishment of long-term habits in the use of specific questions.

Teachers in many parts of the world are mandated reporters of child abuse and maltreatment but very little is known concerning how they question children in suspicious circumstances. Teachers (n=36), who had previously participated in a mock interview scenario designed to characterize their baseline use of various question-types when attempting to elicit sensitive information from children, were given online training in choosing effective questions. They engaged in simulated interviews with a virtual avatar several times in one week and then participated in a mock interview scenario. The amount and proportion of open-ended questions they used increased dramatically after training. The overall number of questions, and amount and proportions of specific and leading questions decreased. In particular, large decreases were observed in more risky yes-no and other forced-choice questions. Given that most teachers may feel the need to ask a child about an ambiguous situation at some point during their careers it is worthwhile to incorporate practice asking effective questions into their training, and the present research suggests that an e-learning format is effective. Additionally, effective questions encourage the development of narrative competence, and we discuss how teachers might include open-ended questions during regular classroom learning.

The author contends that both conceptual and institutional problems permeate psychoanalytic institutes. Although institutional problems are historically based, they also derive from confusions around ill-defined concepts that lead to arbitrariness, authoritarianism, and the stifling of creativity. Psychoanalysis is a humanistic discipline that is touted as a science but is organized as a religion. Problems surrounding the right to train pervade psychoanalytic schisms, and transmission comes through processes of anointment. Institutional "false expertise" invokes the aura of anointment where training analysts pass down received truth through an esoteric pipeline depending on genealogy instead of function. Quasi-religious thinking and politics rush in to fill the gap between the level of claimed knowledge that affords qualification and the far lower level of real knowledge. Institutes should rely on evidence of candidates' performance and engage in open-ended inquiry
