Free Improvisation in Europe:Lecture and Hands-on Workshop, given at 5 different universities in Brazil during February - June 2014

The lecture traces the beginnings of the free improvisation scene in Europe, commencing in the 1960. I present a multitude of video and audio examples of some of the most prominent improvisers of the time.
I focus specifically on the scene that developed around John Stevens and his SME (Spontaneous Music Ensemble). The work of Derek Bailey, specifically his writings in “Improvisation: its nature and practice in music” (1980), will feature.

The practical workshop invites improvisers (beginners to advanced with any instruments) to work with me on several listening and improvisation exercises.
Many of the exercises will be based on the innovative methods as developed by John Stevens in his work “Search and Reflect”. Participants will be able to experiment with a few essential ‘sound/listening’ exercises, guided by myself.
It is envisaged that a small ensemble is formed which will explore several improvisatory strategies. This part is open to all skill levels, all ages and any instrumental groupings.

How Video Lecture Capture affects Student Engagement in a University Computer Programming Course: Attendance, Video Viewing Behaviours and Student Attitudes

Introduction
The use of video capture of lectures in Higher Education is not a recent occurrence with web based learning technologies including digital recording of live lectures becoming increasing commonly offered by universities throughout the world (Holliman and Scanlon, 2004). However in the past decade the increase in technical infrastructural provision including the availability of high speed broadband has increased the potential and use of videoed lecture capture. This had led to a variety of lecture capture formats including pod casting, live streaming or delayed broadcasting of whole or part of lectures.
Additionally in the past five years there has been a significant increase in the popularity of online learning, specifically via Massive Open Online Courses (MOOCs) (Vardi, 2014). One of the key aspects of MOOCs is the simulated recording of lecture like activities. There has been and continues to be much debate on the consequences of the popularity of MOOCs, especially in relation to its potential uses within established University programmes.
There have been a number of studies dedicated to the effects of videoing lectures.
The clustered areas of research in video lecture capture have the following main themes:
• Staff perceptions including attendance, performance of students and staff workload
• Reinforcement versus replacement of lectures
• Improved flexibility of learning
• Facilitating engaging and effective learning experiences
• Student usage, perception and satisfaction
• Facilitating students learning at their own pace
Most of the body of the research has concentrated on student and faculty perceptions, including academic achievement, student attendance and engagement (Johnston et al, 2012).
Generally the research has been positive in review of the benefits of lecture capture for both students and faculty. This perception coupled with technical infrastructure improvements and student demand may well mean that the use of video lecture capture will continue to increase in frequency in the next number of years in tertiary education. However there is a relatively limited amount of research in the effects of lecture capture specifically in the area of computer programming with Watkins 2007 being one of few studies . Video delivery of programming solutions is particularly useful for enabling a lecturer to illustrate the complex decision making processes and iterative nature of the actual code development process (Watkins et al 2007). As such research in this area would appear to be particularly appropriate to help inform debate and future decisions made by policy makers.
Research questions and objectives
The purpose of the research was to investigate how a series of lecture captures (in which the audio of lectures and video of on-screen projected content were recorded) impacted on the delivery and learning of a programme of study in an MSc Software Development course in Queen’s University, Belfast, Northern Ireland. The MSc is conversion programme, intended to take graduates from non-computing primary degrees and upskill them in this area. The research specifically targeted the Java programming module within the course. It also analyses and reports on the empirical data from attendances and various video viewing statistics. In addition, qualitative data was collected from staff and student feedback to help contextualise the quantitative results.
Methodology, Methods and Research Instruments Used
The study was conducted with a cohort of 85 post graduate students taking a compulsory module in Java programming in the first semester of a one year MSc in Software Development. A pre-course survey of students found that 58% preferred to have available videos of “key moments” of lectures rather than whole lectures. A large scale study carried out by Guo concluded that “shorter videos are much more engaging” (Guo 2013). Of concern was the potential for low audience retention for videos of whole lectures.
The lecturers recorded snippets of the lecture directly before or after the actual physical delivery of the lecture, in a quiet environment and then upload the video directly to a closed YouTube channel. These snippets generally concentrated on significant parts of the theory followed by theory related coding demonstration activities and were faithful in replication of the face to face lecture. Generally each lecture was supported by two to three videos of durations ranging from 20 – 30 minutes.
Attendance
The MSc programme has several attendance based modules of which Java Programming was one element. In order to assess the consequence on attendance for the Programming module a control was established. The control used was a Database module which is taken by the same students and runs in the same semester.
Access engagement
The videos were hosted on a closed YouTube channel made available only to the students in the class. The channel had enabled analytics which reported on the following areas for all and for each individual video; views (hits), audience retention, viewing devices / operating systems used and minutes watched.
Student attitudes
Three surveys were taken in regard to investigating student attitudes towards the videoing of lectures. The first was before the start of the programming module, then at the mid-point and subsequently after the programme was complete.
The questions in the first survey were targeted at eliciting student attitudes towards lecture capture before they had experienced it in the programme. The midpoint survey gathered data in relation to how the students were individually using the system up to that point. This included feedback on how many videos an individual had watched, viewing duration, primary reasons for watching and the result on attendance, in addition to probing for comments or suggestions. The final survey on course completion contained questions similar to the midpoint survey but in summative view of the whole video programme.
Conclusions and Outcomes
The study confirmed findings of other such investigations illustrating that there is little or no effect on attendance at lectures. The use of the videos appears to help promote continual learning but they are particularly accessed by students at assessment periods. Students respond positively to the ability to access lectures digitally, as a means of reinforcing learning experiences rather than replacing them. Feedback from students was overwhelmingly positive indicating that the videos benefited their learning. Also there are significant benefits to part recording of lectures rather than recording whole lectures. The behaviour viewing trends analytics suggest that despite the increase in the popularity of online learning via MOOCs and the promotion of video learning on mobile devices in fact in this study the vast majority of students accessed the online videos at home on laptops or desktops However, in part, this is likely due to the nature of the taught subject, that being programming.
The research involved prerecording the lecture in smaller timed units and then uploading for distribution to counteract existing quality issues with recording entire live lectures. However the advancement and consequential improvement in quality of in situ lecture capture equipment may well help negate the need to record elsewhere. The research has also highlighted an area of potentially very significant use for performance analysis and improvement that could have major implications for the quality of teaching. A study of the analytics of the viewings of the videos could well provide a quick response formative feedback mechanism for the lecturer. If a videoed lecture either recorded live or later is a true reflection of the face to face lecture an analysis of the viewing patterns for the video may well reveal trends that correspond with the live delivery.

The use of YouTube Analytics of Video Lecture Capture as a Teaching and Learning Performance Enhancer

Do patterns in the YouTube viewing analytics of Lecture Capture videos point to areas of potential teaching and learning performance enhancement? The goal of this action based research project was to capture and quantitatively analyse the viewing behaviours and patterns of a series of video lecture captures across several computing modules in Queen’s University, Belfast, Northern Ireland. The research sought to establish if a quantitative analysis of viewing behaviours coupled with a qualitative evaluation of the material provided from the students could be correlated to provide generalised patterns that could then be used to understand the learning experience of students during face to face lectures and, thereby, present opportunities to reflectively enhance lecturer performance and the students’ overall learning experience and, ultimately, their level of academic attainment.

Video Lecture Capture : Student Engagement

Video Capture of university lectures enables learners to be more flexible in their learning behaviour, for instance choosing to attend lectures in person or watch later. However attendance at lectures has been linked to academic success and is of concern for faculty staff contemplating the introduction of Video Lecture Capture. This research study was devised to assess the impact on learning of recording lectures in computer programming courses. The study also considered behavioural trends and attitudes of the students watching recorded lectures, such as when, where, frequency, duration and viewing devices used. The findings suggest there is no detrimental effect on attendance at lectures with video materials being used to support continual and reinforced learning with most access occurring at assessment periods. The analysis of the viewing behaviours provides a rich and accessible data source that could be potentially leveraged to improve lecture quality and enhance lecturer and learning performance.

iLectures - Exploring the interactive lecture using web-based broadcasting technology

The continued use of traditional lecturing across Higher Education as the main teaching and learning approach in many disciplines must be challenged. An increasing number of studies suggest that this approach, compared to more active learning methods, is the least effective. In counterargument, the use of traditional lectures are often justified as necessary given a large student population. By analysing the implementation of a web based broadcasting approach which replaced the traditional lecture within a programming-based module, and thereby removed the student population rationale, it was hoped that the student learning experience would become more active and ultimately enhance learning on the module. The implemented model replaces the traditional approach of students attending an on-campus lecture theatre with a web-based live broadcast approach that focuses on students being active learners rather than passive recipients. Students ‘attend’ by viewing a live broadcast of the lecturer, presented as a talking head, and the lecturer’s desktop, via a web browser. Video and audio communication is primarily from tutor to students, with text-based comments used to provide communication from students to tutor. This approach promotes active learning by allowing student to perform activities on their own computer rather than the passive viewing and listening common encountered in large lecture classes. By analysing this approach over two years (n = 234 students) results indicate that 89.6% of students rated the approach as offering a highly positive learning experience. Comparing student performance across three academic years also indicates a positive change. A small data analytic analysis was conducted into student participation levels and suggests that the student cohort's willingness to engage with the broadcast lectures material is high.

Teaching Programming - Understanding Lecture Capture YouTube Analytics

ABSTRACT
The proliferation in the use of video lecture capture in universities worldwide presents an opportunity to analyse video watching patterns in an attempt to quantify and qualify how students engage and learn with the videos. It also presents an opportunity to investigate if there are similar student learning patterns during the equivalent physical lecture. The goal of this action based research project was to capture and quantitatively analyse the viewing behaviours and patterns of a series of video lecture captures across several university Java programming modules. It sought to study if a quantitative analysis of viewing behaviours of Lecture Capture videos coupled with a qualitative evaluation from the students and lecturers could be correlated to provide generalised patterns that could then be used to understand the learning experience of students during videos and potentially face to face lectures and, thereby, present opportunities to reflectively enhance lecturer performance and the students’ overall learning experience. The report establishes a baseline understanding of the analytics of videos of several commonly used pedagogical teaching methods used in the delivery of programming courses. It reflects on possible concurrences within live lecture delivery with the potential to inform and improve lecturing performance.

The Effect of Seat Location in Lecture Theatres on Academic Performance

The purpose of this research study was to investigate and identify possible patterns relating to academic performance on the effects of university students self-selecting where to sit in a lecture theatre.
The key research questions are:
1. Does seating position affect student performance?
2. Do the most academically able and engaged students regularly sit at the front of lecture theatres?
Academic achievement
Preliminary results suggest significant assessment score differences between those that sit at the front and those that sit further the back. Of those that received a grade of 75%+ (Grade A) 6.67% regularly sat at the back. With the same group 46.67% regularly sat at the front. Of the group that scored less than 50% (Grade D) 0% of students regularly sat at the front. 12.50% regularly sat in the middle zones with 37.50% sitting at the back. It was also observed that the remaining numbers did not consistently sit in the same zone.

Temporal movement
There is little evidence of movement between seating zones of the Grade A group throughout the 24 week period. However there was considerable movement with the Grade D group. Although still under analysis there appears be a pattern of students in this group graduating towards the back seating positions over the course of the programme.

Engagement
The frequency of completed entries on PinPoint was also used as an indicator of engagement. With the Grade A group 75% of them regularly completed an entry whereas in the Grade D group this drops to less than 50%.
Further analysis on the attitudinal factors in relational to seating position and performance are ongoing, but preliminary results suggest that those students that scored highly in attitude tended to sit at the front and middle sections.
It would indeed appear that the more highly engaged and academically capable students voluntarily sit at the front for most lectures. Interestingly as the course progresses those who had lesser engagement and below average midterm results tend to began to sit progressively toward the back. If this is a repeatable pattern then a linear regression analysis of the seating positions and midterm results could help predict students in danger of failing.

"C. elegans: modelo biológico do presente e do futuro"

Nos meados da década de 60, o Nobel da Medicina Sidney Brenner propôs a utilização do nemátode bacteriófago, do solo, Caenorhabditis elegans, também conhecido como C. elegans, para estudos de genética e desenvolvimento, dado possuir um conjunto de características que o tornavam o ideal para modelo biológico, nomeadamente a sua pequena dimensão (ca. de 1 mm), facilidade de observação, facilidade de cultivo e manutenção em laboratório, curto ciclo de vida com uma capacidade reprodutiva notável, presença de hermafroditas e machos (5%). O seu artigo seminal de 1974, “The genetics of C. elegans” abriu o caminho para a investigação nesta área. Hoje em dia, revistas como a Nature, Science, Genes and Development, etc… publicam frequentemente os resultados da investigação com recurso a este modelo. É de notar, no entanto, que os nemátodes têm sido utilizados há muito tempo como modelo de estudo, tais como van Beneden, em finais do século XIX, que observando células de Ascaris equorum, descobriu o fenómeno da meiose. O fenómeno da fertilização foi igualmente descoberto num nemátode. Desde a década de setenta até aos nossos dias, o C. elegans tem sido intensamente utilizado para estudos de anatomia interna e sua correlação com linhagens celulares e desenvolvimento. Assim, Sulston e Horvitz elucidaram a origem e desenvolvimento das 959 células somáticas que, de uma forma constante, se produzem nesta espécie (eutelia). Um dos primeiros sistemas a ser estudado foi o sistema nervoso, sendo este nemátode o primeiro animal de que se conhece perfeitamente a identidade de todos os neurónios, a sua linhagem e o circuito nervoso global. Para além de modelo de biologia do desenvolvimento, o C. elegans tem sido alvo de estudo do fenómeno do envelhecimento celular, tendo sido possível identificar os respectivos genes. Kennyon, nos anos 90, e mais recentemente Arantes e Oliveira, têm demonstrado ser possível “prolongar” a vida deste animal de 21 para mais de 180 dias, o que corresponde a 675 anos em vida humana, através de manipulações diversas, tais como agentes mutagénicos, ablação com raio laser, etc.. Também o mecanismo de morte celular programada ou “apoptose” tem sido estudado neste modelo. Em 2002, o Comité Nobel entendeu atribuir o prémio Nobel da Medicina a Brenner, Sulston e Horvitz “for their discoveries concerning genetic regulation of organ development and programmed cell death”. É interessante notar pela leitura de “The common thread”, de John Sulston, a importância decisiva da sequenciação do genoma de C. elegans, em 1998, para o avanço na sequenciação do genoma humano efectuada em 2000, e de cuja mega-equipa Sulston participou de forma decisiva. Finalmente, e como modelo pedagógico, o nemátode C. elegans constitui a escolha ideal para diversas disciplinas dos cursos de Biologia, tais como Biologia celular, Histologia, Biologia do Desenvolvimento, Genética, Etologia, etc….

Représentations de lecture(s) dans l'oeuvre daudétienne

O século XIX testemunhou uma produção literária inegualável, registando vidas e obras de autores, títulos de obras, jornais e revistas. Em tempos de algum individualismo estético-cultural em que cada obra lida parece, ao leitor contemporâneo, a única obra do mercado literário sem qualquer referência a outros autores, e em que o Governo implementa medidas para incentivar comportamentos de leitura, verificamos que o século XIX, além de muitas obras ter produzido, também divulgou muitos autores e suas obras, revelando respeito pela obra literária e testemunhando hábitos de leitura. O estudo da obra de Alphonse Daudet permitirnos- á constatar que os homens de letras liam as obras uns dos outros; que escreviam sobre as obras e partilhavam espaços de criação e produção literárias. A escrita e a leitura, actividades largamente referenciadas em todos os géneros literários adoptados por Daudet, reflectem um lugar comum da sua produção literária como também evidenciam um modus vivendi.

Designing and evaluating an instructional exercise as a supplement to the Fluids & Electrolytes lecture

First year nursing students repeatedly have difficulty recalling, understanding, and applying knowledge from the Fluids & Electrolytes (F&E) class. Although the traditional teaching method of lecturing is appropriate in a situation of knowledge acquisition, this situation refers to a broader context. An alternate teaching method is needed to increase students' understanding of the previously acquired knowledge and its application. This research concerns gaming as a tool for teaching with the focus on process as well as product. An instructional exercise, in the Jeopardy format, is designed to incorporate understanding (through problem-solving), group collaboration, and metacognition. Constructivist philosophy is combined with Instructional Design to construct an exercise that focuses not only on knowledge recall, but also emphasizes thinking, understanding, and the reflective nature of the exercise. The focus of this research is to design and evaluate an exercise as a supplemental teaching method to the lecture presentation of the F&E class.

Le rapport aux traces écrites en situation d'évaluation de lecture de textes narratifs brefs le cas d'élèves au deuxième cycle du secondaire

La présente recherche porte sur les traces écrites laissées par des élèves de quatrième secondaire sur leur texte en situation de préparation à une évaluation sommative. Compte tenu des milieux d'où ils proviennent et de leurs connaissances antérieures, force est de constater que les compétences en lecture de ces élèves sont très variables et ont des conséquences importantes non seulement dans leur cours de français, mais aussi dans toutes les autres matières: plus les élèves avancent dans leur cheminement scolaire, plus les enseignants leur demandent de lire des textes longs et complexes. Pourtant, force est de constater que les résultats en lecture des élèves de quatrième et cinquième secondaire restent faibles. De nombreuses études ont démontré que la lecture de textes narratifs mobilise tous les aspects de la lecture et augmente les compétences générales à lire. Pour les enseignants de français, une façon courante d'évaluer la lecture au deuxième cycle du secondaire est donc de distribuer un texte narratif bref (conte, nouvelle, extrait de roman) à l'avance aux élèves et de leur suggérer d'y laisser des traces écrites de leur réflexion ou des stratégies utilisées, dans le but de favoriser leur compréhension et leur interprétation du texte. Ces traces peuvent prendre la forme, par exemple, de soulignements, de surlignements, d'annotations dans les marges, de schémas. Toutefois, peu de recherches scientifiques se sont attardées aux opinions, aux conceptions et aux pratiques des élèves lorsqu'il s'agit de se préparer à une évaluation de la sorte. Notre recherche, exploratoire et descriptive, vise deux objectifs spécifiques: premièrement, décrire l'investissement, les opinions et attitudes, les conceptions et le mode d'investissement d'élèves de quatrième secondaire et, deuxièmement, décrire les relations entre ces quatre dimensions afin de dresser un portrait global du rapport des élèves aux traces écrites lors de leur préparation à une évaluation de lecture. Pour ce faire, nous avons privilégié une collecte de données en trois phases: après avoir passé, à un échantillon de 41 élèves volontaires, des questionnaires présentant des items à coter sur une échelle de Likert, nous avons observé les textes sur lesquels des traces de leur travail de préparation étaient visibles. Pour finir, nous avons rencontré quatre de ces élèves en entrevue semi-dirigées, choisis en fonction de leurs réponses aux questionnaires et du type de traces qu'ils avaient laissées. Pour augmenter la validité des résultats, les données recueillies à chacune des phases [ont] été croisées afin d'obtenir un maximum d'informations sur le rapport des élèves aux traces écrites. Les résultats obtenus montrent que, malgré le fait que les élèves ont des perceptions généralement assez positives du recours aux traces écrites, les traces qu'ils laissent généralement sur leurs textes sont peu pertinentes dans la mesure où elles ne contribuent pas, pour la plupart, à établir des liens essentiels à la compréhension globale du texte narratif, comme les liens de causalité. Les entrevues nous apprennent que certains élèves ont effectivement l'impression que certaines traces écrites sont plus pertinentes que d'autres, mais qu'ils ignorent souvent lesquelles et comment y recourir pendant leur lecture. Le rapport aux traces écrites est complexe, dépend de la situation et varie d'un individu à l'autre en fonction de plusieurs facteurs contextuels: les expériences et connaissances antérieures de l'élève, la résistance du texte imposé et les contacts avec les pairs. Tous ces facteurs influencent l'élève dans ce qu'il pense, ce qu'il ressent et ce qu'il fait lors de la préparation à une évaluation de lecture.

Habiletés langagières en relation avec la compréhension en lecture chez des adolescents en difficulté d'apprentissage et scolarisés dans un Centre de formation en entreprise et récupération

Dans la société occidentale, la maîtrise ou non de la lecture a une influence majeure sur le fonctionnement d'un individu dans la société en influençant sa réussite scolaire et son insertion socioprofessionnelle. Dans ce mémoire, nous nous interrogeons à savoir quelles sont les habiletés langagières entrant en relation avec la compréhension en lecture. Une évaluation individuelle des processus d'identification des mots, de la compréhension orale et écrite de même qu'une évaluation du niveau de vocabulaire maîtrisé à l'oral ont été effectuées auprès d'adolescents âgés de 15 à 16 ans. Les analyses montrent que leurs difficultés de compréhension en lecture ne sont pas associées à des difficultés d'identification de mots, mais bien à une faiblesse au niveau du vocabulaire oral. Ces résultats vont dans le même sens que les recherches sur le sujet qui démontrent que le vocabulaire joue un rôle important dans la compréhension de texte chez les adolescents.
