A teachable-agent-based game affording collaboration and competition: evaluating math comprehension and motivation

This paper presents an educational game in mathematics based on an apprenticeship model using a teachable agent, as well as an evaluative study of how the game affects (1) conceptual understanding and (2) attitudes towards mathematics. In addition, we discuss how collaborative and competitive affordances of the game may affect understanding and motivation. 19 students played the game in pairs once a week during math lessons for 7?weeks (the game-playing group) while another 19 students followed the regular curriculum (the control group). Math comprehension scores increased significantly for the game-playing group but not the control group (p?<?0.05). However, there was no significant difference in attitude change between the two groups. Post hoc analyses indicated that game-playing primarily affected students?? confidence in explaining math to a peer, but not their enjoyment of doing so. Collaborative and competitive activities seem to carry a strong motivational influence for students to play the game.     

Constituting the workplace curriculum

This paper advances some bases for a workplace curriculum. These are premised on conceptions of curriculum as intents directed to individuals’ progression towards full and effective workplace performance, yet whose enactment is shaped by workplace factors and is ultimately experienced by workers as learners. So whether the intentions will be realized is likely premised on the support (affordances) for their enactment by interests within the workplace. Workplace affordances, like those in educational institutions, emphasize the role that the norms and social practices that comprise workplaces play in regulating individuals’ engagement in and learning through work. The degree to which these affordances invite, structure, support, and guide participation, and are likely to engage workers in the kinds of thinking, acting, and learning required for effective workplace performance, is important for developing effective vocational practice. The conception of an ideal curriculum directed towards full participation is subject to the affordances of the interests of managers, co‐workers, and factors affecting production, as well as the intentionalities of worker‐learners themselves. These concepts may well provide ways of thinking about curriculum more broadly as participatory practices.     

Learning Throughout Working Life: Interdependencies at work

Recently the meaning of lifelong learning has been transformed by economic imperatives from a focus on securing personal development to individuals' maintenance of their vocational practice throughout their working lives. These imperatives aim to reshape the responsibilities and goals for adults' learning throughout their working lives. This paper proposes an account of learning at work as a component of individual's development across their lifespan. It argues that learning throughout working life is an inevitable product of everyday thinking and acting, shaped by the work practices in which individuals participate. However, the quality of learning is contingent on the kinds of activities individuals engage in and the guidance they can access. These contributions are referred to as the activities and interdependencies afforded by the workplace. Continuities and discontinuities in development through working life can be understood in part by patterns of participation in these social practices. Yet there is tension between individuals' interest in participation and the affordance of the work practices in which they act. It is proposed that, although able to regulate their participation, ultimately individuals' ability to maintain their vocational practice is constrained by the way workplaces afford opportunities for engagement and interactions.     

A critical discourse analysis of sexuality education in the Australian curriculum

This article examines the sexuality education component of the national Australian Curriculum: Health and Physical Education (AC:HPE) with a focus on sexuality education discourses. A critical discourse analysis explored official AC:HPE documents in relation to sexuality education; the sexuality education discourses present within these documents; teacher roles and expectations associated with each discourse; and Australia’s broader social context in relation to education. Findings reveal that the AC:HPE emphasises a teacher-facilitated approach to sexuality education, which contrasts with teacher-centred work dominating the field prior to its release. This approach is in line with recent shifts in education towards strengths-based learning in which students are encouraged to think critically about issues. Despite these emphases, and while the AC:HPE is meant to be used flexibly as a guideline or framework, certain ambiguities within it may leave teachers’ roles open to interpretation and practices therefore unchanged or undisputed.     

The effects of first programming language on college students’ computing attitude and achievement: a comparison of graphical and textual languages

Background and Context: The relationship between novices’ first programming language and their future achievement has drawn increasing interest owing to recent efforts to expand K–12 computing education. This article contributes to this topic by analyzing data from a retrospective study of more than 10,000 undergraduates enrolled in introductory computer science courses at 118 U.S. institutions of higher education.

Objective: We explored the relationship between students’ first programming languages and both their final grades in an introductory computer science course and their attitudes about programming.

Method: Multiple matching techniques compared those whose first language was graphical (e.g., Scratch), textual (e.g., Java), or absent prior to college.

Findings: Having any prior programming experience had positive effects on both attitudes about programming and grades in introductory computer science courses. Importantly, students whose first language was graphical had higher grades than did students whose first language was textual, when the languages were introduced in or before early adolescent years.

Implications: Learning any computer language is better than learning none. If programming is to be taught to students before early adolescence, it is advised to start with a graphical language. Future work should investigate the transition between different types of programming languages.     

Information virus: Contaminated subject matter in instructional materials

Summary In industralized nations, information anxiety and information overload are topics of discussion. Books have been written about how to evaluate literature reviews where hundreds of items are being assessed.In many developing nations, information starvation is more the norm. The authors have begun exploring how information viruses can cause invalid content to work into an instructional design and permeate deeply into an educational system, ultimately producing good learning of subject matter that is out of date, contains serious omissions, or is inaccurate or misleading.There are ways to forestall information viruses from entering instructional materials. Much could be achieved by using new information search technologies and telecommunications links, fostering better appreciation of basic information technology, and upgrading the role of librarian in the instructional design process. Changes are needed in attitudes of government ministries and foreign aid funding agencies in order to support efforts to prevent information viruses from occurring.Dr. David Giltrow is an independent consultant specializing in the application of educational technology in developing countries.     

Subjectivity, Learning and Work: Sources and Legacies

Individuals’ dispositions have long been held to direct and energise cognition in ways that shape how they experience and respond to events in the social world. Therefore, a consideration of these dispositions is likely to be helpful in understanding the inter-psychological processes between individual and social world that frame contemporary socio-cultural accounts of learning. Here, the specific concern is to elaborate the sources, legacies and potency of individuals’ dispositions in the learning of occupational practice through these processes. Having reviewed ideas about the dispositional underpinnings of individuals’ construal and construction of the knowledge required for work, these conceptions are exercised through illuminating the roles dispositions play in the process of constructing the knowledge required for an occupational practice (i.e. hairdressing). The study reported here combines workplace ethnography and problem-solving tasks to identify the source of these subjectivities, how they shape individuals’ cognitive processes at work tasks and their learning through participation in vocational practice. In all, it identified how individuals’ dispositions arise through socially-shaped life histories or ontogenies, albeit in person-dependent ways. The participants’ conceptions, preferences and procedures that shape their learning and the enactment of their practice were found to be products of earlier socially-derived experiences, thereby making them personally-subjective. These personally-subjective dispositions were identified as shaping how these individuals engage in work, learning and the ongoing remaking of work activities, because they influence inter-psychological processes that comprise the immediate experiences that constitute the enactment of these activities. So, this suggests that the sociogeneses of knowledge and learning likely includes personally unique social contributions that arise through ontogeny.     

LEARNING THROUGHOUT WORKING LIFE: A RELATIONAL INTERDEPENDENCE BETWEEN PERSONAL AND SOCIAL AGENCY

ABSTRACT:  Individuals actively and continually construct the knowledge required for their working lives. Two outcomes arise from this constructive process: (i) individual change (i.e. learning) and (ii) the remaking of culturally-derived practices comprising work. These arise through a relational interdependence between the contributions and agency of the personal and the social. The relationship is interdependent because neither the social nor personal contributions alone are sufficient. The social experience is important for articulating and providing access to work performance requirements. However, personal factors such as individuals' capacities, subjectivities and agency shape how workers interpret and engage with what they experience and, consequently, how they learn and remake practice throughout their working life. This case is elaborated through a discussion about learning with considerations of intersubjectivity, personal epistemologies, pedagogy and curriculum as experience.
