The role of pedagogical tools in active learning: a case for sense-making
Evidence from the research literature indicates that both audience response
systems (ARS) and guided inquiry worksheets (GIW) can lead to greater student
engagement, learning, and equity in the STEM classroom. We compare the use of
these two tools in large enrollment STEM courses delivered in different
contexts, one in biology and one in engineering. The instructors studied
utilized each of the active learning tools differently. In the biology course,
ARS questions were used mainly to check in with students and assess if they
were correctly interpreting and understanding worksheet questions. The
engineering course presented ARS questions that afforded students the
opportunity to apply learned concepts to new scenarios towards improving
students conceptual understanding. In the biology course, the GIWs were
primarily used in stand-alone activities, and most of the information necessary
for students to answer the questions was contained within the worksheet in a
context that aligned with a disciplinary model. In the engineering course, the
instructor intended for students to reference their lecture notes and rely on
their conceptual knowledge of fundamental principles from the previous ARS
class session in order to successfully answer the GIW questions. However, while
their specific implementation structures and practices differed, both
instructors used these tools to build towards the same basic disciplinary
thinking and sense-making processes of conceptual reasoning, quantitative
reasoning, and metacognitive thinking.Comment: 20 pages, 5 figure

Transitivity for height versus speed: To what extent do the under-7s really have a transitive capacity?
This is the author's accepted manuscript. The final published article is available from the link below. Copyright @ 2011 Psychology Press.Transitive inference underpins many human reasoning competencies. The dominant task (the âextensive training paradigmâ) employs many items and large amounts of training, instilling an ordered series in the reasoner's mind. But findings from an alternative âthree-term paradigmâ suggest transitivity is not present until 7 + years. Interestingly, a second alternative paradigm (the âspatial taskâ), using simultaneously displayed height relationships to form premise pairs, can uphold the 4-year estimate. However, this paradigm risks cueing children and hence is problematic. We investigated whether a height-task variant might correspond to a more ecologically valid three-term task. A total of 222 4â6-year-olds either completed a modified height task, including an increased familiarisation phase, or a computer-animated task about cartoon characters running a race in pairs. Findings confirmed that both tasks were functionally identical. Crucially, 4-year-olds were at chance on both, whereas 6-year-olds performed competently. These findings contrast with estimates from all three paradigms considered. A theoretical evaluation of our tasks and procedures against previous ones, leads us to two conclusions. First, our estimate slightly amends the 7-year estimate offered by the three-term paradigm, with the difference explained in terms of its greater relevance to child experiences. Second, our estimate can coexist alongside the 4-year estimate from the extensive training paradigm. This is because, applying a recently developed âdual-processâ conception of reasoning, anticipates that extensive training benefits a species-general associative system, while the spatial paradigm and three-term paradigm can potentially index a genuinely deductive system, which has always been the target of transitive research
Integration of BPM systems
New technologies have emerged to support the global economy where for instance suppliers, manufactures and retailers are working together in order to minimise the cost and
maximise efficiency. One of the technologies that has become a buzz word for many businesses is business process management or BPM. A business process comprises activities
and tasks, the resources required to perform each task, and the business rules linking these activities and tasks. The tasks may be performed by human and/or machine actors.
Workflow provides a way of describing the order of execution and the dependent relationships between the constituting activities of short or long running processes.
Workflow allows businesses to capture not only the information but also the processes that transform the information - the process asset (Koulopoulos, T. M., 1995). Applications which involve automated, human-centric and collaborative processes across organisations are
inherently different from one organisation to another. Even within the same organisation but over time, applications are adapted as ongoing change to the business processes is seen as the norm in todayâs dynamic business environment. The major difference lies in the specifics of business processes which are changing rapidly in order to match the way in which businesses operate. In this chapter we introduce and discuss Business Process Management (BPM) with a focus on the integration of heterogeneous BPM systems across multiple organisations. We identify the problems and the main challenges not only with regards to technologies but also in the social and cultural context. We also discuss the issues that have arisen in our bid to find the solutions
Technology assessment between risk, uncertainty and ignorance
The use of most if not all technologies is accompanied by negative side effects, While we may profit from todayâs technologies, it is most often future generations who bear most risks. Risk analysis therefore becomes a delicate issue, because future risks often cannot be assigned a meaningful occurance probability. This paper argues that technology assessement most often deal with uncertainty and ignorance rather than risk when we include future generations into our ethical, political or juridal thinking. This has serious implications as probabilistic decision approaches are not applicable anymore. I contend that a virtue ethical approach in which dianoetic virtues play a central role may supplement a welfare based ethics in order to overcome the difficulties in dealing with uncertainty and ignorance in technology assessement
Towards understanding models for statistical literacy: A literature review.
Despite statistical literacy being relatively new in statistics education research, it needs special attention as attempts are being made to enhance the teaching, learning and assessing of this strand. It is important that teachers are aware of the challenges of teaching this literacy. The growing importance of statistics in today's information world and conceptions and components of statistical literacy are outlined. Frameworks for developing statistical literacy from research literature are considered next. Strengths and weaknesses of the models are considered. Examples of tasks used in statistics education research are provided to explain the levels of thinking. The paper concludes with some implications for teaching and research
The emergence of choice: Decision-making and strategic thinking through analogies
Consider the chess game: When faced with a complex scenario, how does understanding arise in oneâs mind? How does one integrate disparate cues into a global, meaningful whole? how do humans avoid the combinatorial explosion? How are abstract ideas represented? The purpose of this paper is to propose a new computational model of human chess intuition and intelligence. We suggest that analogies and abstract roles are crucial to solving these landmark problems. We present a proof-of-concept model, in the form of a computational architecture, which may be able to account for many crucial aspects of human intuition, such as (i) concentration of attention to relevant aspects, (ii) \ud
how humans may avoid the combinatorial explosion, (iii) perception of similarity at a strategic level, and (iv) a state of meaningful anticipation over how a global scenario \ud
may evolve
Argumentation in school science : Breaking the tradition of authoritative exposition through a pedagogy that promotes discussion and reasoning
The value of argumentation in science education has become internationally recognised and has been the subject of many research studies in recent years. Successful introduction of argumentation activities in learning contexts involves extending teaching goals beyond the understanding of facts and concepts, to include an emphasis on cognitive and metacognitive processes, epistemic criteria and reasoning. The authors focus on the difficulties inherent in shifting a tradition of teaching from one dominated by authoritative exposition to one that is more dialogic, involving small-group discussion based on tasks that stimulate argumentation. The paper builds on previous research on enhancing the quality of argument in school science, to focus on how argumentation activities have been designed, with appropriate strategies, resources and modelling, for pedagogical purposes. The paper analyses design frameworks, their contexts and lesson plans, to evaluate their potential for enhancing reasoning through foregrounding the processes of argumentation. Examples of classroom dialogue where teachers adopt the frameworks/plans are analysed to show how argumentation processes are scaffolded. The analysis shows that several layers of interpretation are needed and these layers need to be aligned for successful implementation. The analysis serves to highlight the potential and limitations of the design frameworks
