Cognitive Load Theory: A Broader View on the Role of Memory in Learning and Education

According to cognitive load theory (CLT), the limitations of working memory (WM) in the learning of new tasks together with its ability to cooperate with an unlimited long-term memory (LTM) for familiar tasks enable human beings to deal effectively with complex problems and acquire highly complex knowledge and skills. With regard to WM, CLT has focused to a large extent on learning task characteristics, and to a lesser extent on learner characteristics to manage WM load and optimize learning through instructional design. With regard to LTM, explanations of human learning and cognition have mainly focused on domain-general skills, instead of domain-specific knowledge held in LTM. The contributions to this special issue provide a broader cognitive load view on the role of memory in learning and education by presenting the historical roots and conceptual development of the concept of WM, as well as the theoretical and practical implications of current debates about WM mechanisms (Cowan 2014), by presenting an updated model of cognitive load in which the physical learning environment is considered a distinct causal factor for WM load (Choi et al. 2014), by an experimental demonstration of the effects of persistent pain on the available WM resources for learning (Smith and Ayres 2014), and by using aspects of evolutionary educational psychology to argue for the primacy of domain-specific knowledge in human cognition (Tricot and Sweller 2014).     

Theoretically grounded guidelines for assessing learning progress: cognitive changes in ill-structured complex problem-solving contexts

It is generally accepted that the cognitive development for a wide range of students can be improved through adaptive instruction-learning environments optimized to suit individual needs (e.g., Cronbach, Am Psychol 12:671?C684, 1957; Lee and Park, in Handbook of research for educational communications and technology, Taylor & Francis Group, Routledge, New York, pp 469?C484, 2007; Shute and Zapata-Rivera, in Handbook of research for educational communications and technology, Taylor & Francis Group, Routledge, New York, pp 227?C294, 2007). It is vital in adaptive instruction to diagnose an individual??s learning progress in terms of cognitive changes in complex problem-solving contexts. This study conceptualized the levels of learning progress, associating the development of expertise in domain learning with the structural features of mental models. The theory of mental models accounts for how people conceptualize problem situations. That is, a mentally represented problem space is a structure including diverse relationships. It is necessary that assessment tools be adapted for the complex, dynamic structure of mental models so that the diagnostic, formative information become more precise. In short, the proposed stage-sequential model of learning progress was theoretically justified as being able to serve as a diagnostic model of learning progress.     

The Value of Applied Research: Retrieval Practice Improves Classroom Learning and Recommendations from a Teacher, a Principal, and a Scientist

Over the course of a 5-year applied research project with more than 1,400 middle school students, evidence from a number of studies revealed that retrieval practice in authentic classroom settings improves long-term learning (Agarwal et al. 2009; McDaniel et al., Journal of Educational Psychology 103:399–414, 2011; McDaniel et al. 2012; Roediger et al., Journal of Experimental Psychology: Applied 17:382–395, 2011a). Retrieval practice, or the use of quizzes and exams to engage and enhance retrieval processes, has been widely established as an effective strategy for facilitating learning in laboratory settings (e.g., Roediger et al. 2011c). In this article, we review recent findings from applied research that demonstrate that retrieval practice enhances long-term classroom learning, delayed quizzes are particularly potent for retention, quizzes benefit students’ transfer to novel quiz items, and quizzes with feedback improve students’ learning and metacognitive awareness. In addition to generating evidence to support retrieval-based learning, these applied research studies also enhanced the professional development of the teachers, administrators, and scientists involved in the project. In this article, it is our hope that by sharing what we have learned from a variety of perspectives, applied scientific research in K-12 classrooms will continue to be explored and generated at local, state, and national levels, improving student learning and educational decision-making.     

Infusing Authentic Inquiry into Biotechnology

Societal benefit depends on the general public’s understandings of biotechnology (Betsch in World J Microbiol Biotechnol 12:439–443, 1996; Dawson and Cowan in Int J Sci Educ 25(1):57–69, 2003; Schiller in Business Review: Federal Reserve Bank of Philadelphia (Fourth Quarter), 2002; Smith and Emmeluth in Am Biol Teach 64(2):93–99, 2002). A National Science Foundation funded survey of high school biology teachers reported that hands-on biotechnology education exists in advanced high school biology in the United States, but is non-existent in mainstream biology coursework (Micklos et al. in Biotechnology labs in American high schools, 1998). The majority of pre-service teacher content preparation courses do not teach students appropriate content knowledge through the process of inquiry. A broad continuum exists when discussing inquiry-oriented student investigations (Hanegan et al. in School Sci Math J 109(2):110–134, 2009). Depending on the amount of structure in teacher lessons, inquiries can often be categorized as guided or open. The lesson can be further categorized as simple or authentic (Chinn and Malhotra in Sci Educ 86(2):175–218, 2002). Although authentic inquiries provide the best opportunities for cognitive development and scientific reasoning, guided and simple inquiries are more often employed in the classroom (Crawford in J Res Sci Teach 37(9):916–937, 2000; NRC in Inquiry and the national science education standards: a guide for teaching and learning, 2000). For the purposes of this study we defined inquiry as “authentic” if original research problems were resolved (Hanegan et al. in School Sci Math J 109(2):110–134, 2009; Chinn and Malhotra in Sci Educ 86(2):175–218, 2002; Roth in Authentic school science: knowing and learning in open-inquiry science laboratories, 1995). The research question to guide this study through naturalistic inquiry research methods was: How will participants express whether or not an authentic inquiry experience enhanced their understanding of biotechnology? As respondents explored numerous ideas in order to develop a workable research question, struggled to create a viable protocol, executed their experiment, and then evaluated their results, they commented on unexpected topics regarding the nature of science as well as specific content knowledge relating to their experiments. Four out of five participants reported they learned the most during authentic inquiry laboratory experience.     

“I See Trayvon Martin”: What Teachers Can Learn from the Tragic Death of a Young Black Male

The goal of this article is to examine the racially hostile environment of U.S. public schooling towards Black males. Drawing on the work of Foucault (Discipline and punish. The birth of the prison, Penguin Books, London, 1977; Michel Foucault: beyond structuralism and hermeneutics, The Harvester Press, Brighton, 1982) regarding the construction of society’s power relations and Bourdieu’s (Power and ideology in education, Oxford University Press, New York, 1977; Handbook of theory and research for the sociology of education. Greenwood Press, New York, 1986; The logic of practice. Polity Press, Cambridge, 1990) work concerning how beliefs are established, this article demonstrates how power operates within schools alongside racism, racial profiling, and gender stereotypes to criminalize Black males. Additionally, the utilization of the theoretical lenses of populational reasoning (Popkewitz in Struggling for the soul: the politics of schooling and the construction of the teacher, Teachers College Press, New York, 1998), conceptual narrative (Somers and Gibson in Social theory and the politics of identity, Blackwell, Cambridge, 1994), and critical race theory (Delgado and Stefancic 2001) links the common narrative and the cultural memory of Black males to the death of Trayvon Martin and the treatment of Black males in schools.     

Small Talk: Children’s Everyday ‘Molecule’ Ideas

This paper reports on 6–11-year-old children’s ‘sayings and doings’ (Harré 2002) as they explore molecule artefacts in dialectical-interactive teaching interviews (Fleer, Cultural Studies of Science Education 3:781–786, 2008; Hedegaard et al. 2008). This sociocultural study was designed to explore children’s everyday awareness of and meaning-making with cultural molecular artefacts. Our everyday world is populated with an ever increasing range of molecular or nanoworld words, symbols, images, and games. What do children today say about these artefacts that are used to represent molecular world entities? What are the material and social resources that can influence a child’s everyday and developing scientific ideas about ‘molecules’? How do children interact with these cognitive tools when given expert assistance? What meaning-making is afforded when children are socially and materially assisted in using molecular tools in early chemical and nanoworld thinking? Tool-dependent discursive studies show that provision of cultural artefacts can assist and direct developmental thinking across many domains of science (Schoultz et al., Human Development 44:103–118, 2001; Siegal 2008). Young children’s use of molecular artefacts as cognitive tools has not received much attention to date (Jakab 2009a, b). This study shows 6–11-year-old children expressing everyday ideas of molecular artefacts and raising their own questions about the artefacts. They are seen beginning to domesticate (Erneling 2010) the words, symbols, and images to their own purposes when given the opportunity to interact with such artefacts in supported activity. Discursive analysis supports the notion that using ‘molecules’ as cultural tools can help young children to begin ‘putting on molecular spectacles’ (Kind 2004). Playing with an interactive game (ICT) is shown to be particularly helpful in assisting children’s early meaning-making with representations of molecules, atoms, and their chemical symbols.     

Agnotology, Scientific Consensus, and the Teaching and Learning of Climate Change: A Response to Legates, Soon and Briggs

Agnotology is a term that has been used to describe the study of ignorance and its cultural production (Proctor in Agnotology: the making and unmaking of ignorance. Stanford University Press, Stanford, 2008). For issues that are contentious in the societal realm, though largely not in the scientific realm, such as human evolution or the broad basics of human-induced climate change, it has been suggested that explicit study of relevant misinformation might be a useful teaching approach (Bedford in J Geogr 109(4):159–165, 2010). Recently, Legates et al. (Sci Educ. doi:10.1007/s11191-013-9588-3, 2013) published an aggressive critique of Bedford’s (J Geogr 109(4):159–165, 2010) proposals. However, the critique is based on a comprehensive misinterpretation of Bedford’s (J Geogr 109(4):159–165, 2010) paper. Consequently, Legates et al. (Sci Educ. doi:10.1007/s11191-013-9588-3, 2013) address arguments not actually made by Bedford (J Geogr 109(4):159–165, 2010). This article is a response to Legates et al. (Sci Educ. doi:10.1007/s11191-013-9588-3, 2013), and demonstrates their errors of interpretation of Bedford (J Geogr 109(4):159–165, 2010) in several key areas: the scientific consensus on climate change; misinformation and the public perception of the scientific consensus on climate change; and agnotology as a teaching tool. We conclude by arguing that, although no single peer-reviewed publication on climate change, or any other scientific issue, should be accepted without due scrutiny, the existence of a scientific consensus—especially one as overwhelming as exists for human-induced climate change—raises the level of confidence that the overall findings of that consensus are correct.     

Epistemic trajectories: mentoring in a game design practicum

Innovative professionals rely on a specific ways of thinking to solve the nonstandard problems that come up in practice (Goodwin, Am Anthropol 96(3):606–633, 1994; Schön, The reflective practitioner: how professionals think in action, 1983; Educating the reflective practitioner: toward a new design for teaching and learning in the professions, 1987; Sullivan, Work and integrity: the crisis and promise of professionalism in America, 1995). The professions have reproductive practices for transmitting these ways of thinking, such as practica (Schön, Educating the reflective practitioner: toward a new design for teaching and learning in the professions, 1987). In this paper, we examine the learning relationship between a mentor and team of college students through an ethnographic study of a game design practicum at a European arts school. To examine the role that the mentor played in this practicum, we use two theoretical constructs. Epistemic frames—the configurations of the skills, knowledge, identities, values, and epistemologies that professionals use to think in innovative ways—provide a model for examining professional expertise (Shaffer, Comput Educ, 46(3):223–234, 2006a). Epistemic network analysis (ENA) (Shaffer et al., Int J Learn Media, 1(2):33–53, 2009) is a method for quantifying changes in epistemic frames (Shaffer, The bicycle helmets of “Amsterdam”: computer games and the problem of transfer, 2010). Our results here suggest that the mentor leads the team on a path that illuminates the nature of learning to think professionally, as well the function of a mentor in that process. We argue that the mentor, rather than providing a direct map to a professional vantage point, scaffolds aspects of the epistemic frame of game design that, in turn, aid in the development of a more professional frame. Using ENA to understand the way that mentors help coach learners to develop epistemic frames should be useful for further studies of professional education, as well as for studies of apprenticeship-based programs for youth.     

Educational Technologists: Leading Change for a New Paradigm of Education

The transition from the industrial age to the information age has happened and is still happening in our society (Duffy, 2009). However, our current educational systems still operate based on the needs of the industrial-age society (Watson, Watson, & Reigeluth, n.d), making them among the least impacted organizations (Reigeluth & Joseph, 2002). This misalignment between schools and society takes the form of a discrepancy between what and how we teach students in schools and how schools are organized and operated (Banathy, 1991; Hargreaves, 1999; Wagner et al., 2006). Educational systems should address current students’ needs to facilitate their learning process and better preparethem for their future lives in society (Collins & Halverson, 2009). In this article, we explain how we envision the new paradigm of education and what roles educational technologists should play to help transform educational systems to this new paradigm.     

School district triggers for reconstructing professional knowledge

In a recent publication, Senge (All systems go: the change imperative for whole system reform. Corwin Press, Thousand Oaks, 2010, x) stated ??at no time in history has there been a more powerful need for a new vision of the purpose of education.?? Increasingly citizens, academics and practitioners are calling for radical changes to educational practices to meet the needs of a knowledge-based society in the twenty-first century (Dede in 21st Century skills: rethinking how students learn. Solution Tree Press, Bloomington, 2010; Hargreaves and Shirley in The fourth way: the inspiring future for educational change. Corwin Press, Thousand Oaks, 2009). Accomplishing such substantive educational change requires that individual educators collectively reshape their personal professional knowledge (Connelly and Clandinin in Teachers as curriculum planners: narratives of experiences. OISE Press, Toronto, 1988; Elbaz in Curriculum Inq 11(1):43?C71, 1981) and adapt their personal mental models (Duffy in J Staff Dev 24(1):30?C36, 2003). In 2000, we began a longitudinal study on the role of a school district in facilitating significant educational reform which required adaptations to individual and collective mental models of professional practice. Annually we conducted intensive interviews with a large sample of teachers, school and system administrators in this large Ontario, Canada school district. Recently, we conducted a retrospective analysis of these data collected in order to identify the conditions necessary for a large organization to support knowledge-creation and dissemination. In this paper, we identify three school district actions that triggered individual educators to challenge and reconstruct their professional personal practical mental models of the teaching and learning. First, improved student learning became the central focus of the school district. Second, the school district stressed and created opportunities for educators to collectively engage in professional dialogue about their practice. Third, the school district emphasized the importance of educators individually and collectively using evidence to assess whether their actions improved student learning.     

Because trucks aren’t bicycles: orthographic complexity as an important variable in reading research

Severe enduring reading- and writing-accuracy difficulties seem a phenomenon largely restricted to nations using complex orthographies, notably Anglophone nations, given English’s highly complex orthography (Geva and Siegel, Read Writ 12:1–30, 2000; Landerl et al., Cognition 63:315–334, 1997; Share, Psychol Bull 134(4):584–615, 2008; Torgesen and Davis, J Exp Child Psychol 63:1–21, 1996; Vellutino, J Learn Disabil 33(3):223, 2000). They seem rare in transparent orthography nations such as Finland, which use highly regular spelling and few spelling rules beyond letter sounds, and most children read and write with impressive accuracy by the end of Year 1 (Holopainen et al., J Learn Disabil 34(5):401–413, 2001; Seymour et al., Br J Psychol 94:143–174, 2003; Spencer and Hanley, Br J Psychol 94(1):1–29, 2003; J Res Read 27(1):1–14, 2004). Orthographic complexity has strong and diverse impacts on reading, writing and academic development (Aro, Learning to read: The effect of orthography, 2004; Galletly and Knight, Aust J Learn Disabil 9(4):4–11, 2004; Aust Educ Res 38(3):329–354, 2011). Despite these strong effects, orthographic complexity is rarely included as a variable in reading research studies considering evidence from both Anglophone (complex orthography) and transparent-orthography readers, or included in discussion of factors influencing results. This paper discusses the differences in reading-accuracy development and difficulties evidenced in studies of Anglophone (complex-orthography) and transparent-orthography readers. It then explores instances of orthographic complexity not being considered in studies where it may have impacted results. This disregarding of orthographic complexity as a variable in research studies appears an oversight, one likely to be contributing to continuing confusion on many aspects of reading and writing development in both healthy- and low-progress readers. Needs for research in these areas are discussed.     

Threshold capabilities: threshold concepts and knowledge capability linked through variation theory

The Threshold Capability Integrated Theoretical Framework (TCITF) is presented as a framework for the design of university curricula, aimed at developing graduates’ capability to deal with previously unseen situations in their professional, social, and personal lives. The TCITF is a new theoretical framework derived from, and heavily dependent upon, the ideas of the Threshold Concepts Framework (Meyer and Land 2003a; Land et al. 2006) and Capability Theory (Bowden and Marton 1998; Bowden et al. 2000; Bowden 2004). Capability theory is firmly based in phenomenography and variation theory, is concerned with the development of knowledge capability, but has had limited application in practice. The threshold concepts framework has enjoyed greater acceptance by a large range of academics in many fields. This acceptance has initially focussed on analytic studies of what constitutes a threshold concept—and the location and distribution of such concepts—in a given domain. In many instances subsequent attention has focussed on issues of pedagogy and assessment, including the design of curricula. We propose a merging of capability theory and the threshold concepts framework and argue that capability and variation theories provide the ideal mechanism for developing a strong pedagogical approach based on newly emerging knowledge of the critical features of threshold concepts within different domains.     

Development of a Short-Form Measure of Science and Technology Self-efficacy Using Rasch Analysis

Despite an increased focus on science, technology, engineering, and mathematics (STEM) in U.S. schools, today’s students often struggle to maintain adequate performance in these fields compared with students in other countries (Cheek in Thinking constructively about science, technology, and society education. State University of New York, Albany, 1992; Enyedy and Goldberg 2004; Mandinach and Lewis 2006). In addition, despite considerable pressure to promote the placement of students into STEM career fields, U.S. placement is relatively low (Sadler et al. in Sci Educ 96(3):411–427, 2012; Subotnik et al. in Identifying and developing talent in science, technology, engineering, and mathematics (STEM): an agenda for research, policy and practice. International handbook, part XII, pp 1313–1326, 2009). One explanation for the decline of STEM career placement in the U.S. rests with low student affect concerning STEM concepts and related content, especially in terms of self-efficacy. Researchers define self-efficacy as the internal belief that a student can succeed in learning, and that understanding student success lies in students’ externalized actions or behaviors (Bandura in Psychol Rev 84(2):191–215, 1977). Evidence suggests that high self-efficacy in STEM can result in student selection of STEM in later educational endeavors, culminating in STEM career selection (Zeldin et al. in J Res Sci Teach 45(9):1036–1058, 2007). However, other factors such as proficiency play a role as well. The lack of appropriate measures of self-efficacy can greatly affect STEM career selection due to inadequate targeting of this affective trait and loss of opportunity for early intervention by educators. Lack of early intervention decreases selection of STEM courses and careers (Valla and Williams in J Women Minor Sci Eng 18(1), 2012; Lent et al. in J Couns Psychol 38(4), 1991). Therefore, this study developed a short-form measure of self-efficacy to help identify students in need of intervention.     

A scalable and incremental project-based learning approach for CS1/CS2 courses

Cupi2 is a project that promotes an integral solution to problems in teaching/learning programming using a large and structured courseware, and a student-centered pedagogical model (Villalobos and Casallas 2006a; Villalobos et al. 2009a, b; Jiménez and Villalobos 2010). As a cornerstone of Cupi2, we use incremental projects intended to motivate students, and to develop high-level programming skills throughout their learning. A critical factor of these projects is that they are specially designed so that students are engaged in activities that complete a scaffold of a complete program. However, both the scaffolds and the activities needed to complete these incomplete programs must be arranged carefully by instructors in order to stress the adequate contents for students, and at the same time, to help those students acquire programming skills effectively. Jointly, scaffold versions need to comply with high quality standards, representing a high time consuming activity for instructors, and therefore, increased costs for institutions. In this paper, we describe the way we overcome these challenges using a software factory that supports the projects’ design in a scalable way.     

In search of consolidation of short-term memory in nonhuman animals

Wixted (Annual Review of Psychology, 55, 235 – 269, 2004) has argued that forgetting is due to consolidation failure. Previous research with humans and nonhuman animals has reported evidence for consolidation in intermediate or long-term memory (LTM). The present study examines whether consolidation occurs in short-term memory in pigeons. Delayed matching-to-sample accuracy was reduced when retroactive interference (an extraneous task in Experiment 1 or houselight illumination in Experiment 2) was interpolated in the retention interval. Accuracy was not greater, however, when interference occurred at the end of the retention interval, as compared with when it occurred at the beginning. That is, there was no evidence for consolidation in short-term memory for pigeons. We did find, however, the beginning–end effect originally reported by Roberts and Grant (Journal of Experimental Psychology: Animal Behavior Processes, 4, 219–236, 1978) and the recovery from forgetting reported by White and Brown (Journal of the Experimental Analysis of Behavior, 96, 177–189, 2011). The results are discussed in relation to temporal distinctiveness theory as an alternative to consolidation.     

An easy-to-hard effect after nonreinforced preexposure in a sweetness discrimination

Experiments 1A and 1B used a taste-aversion procedure with rats to demonstrate that exposure to easily discriminated flavors along a dimension (1 % and 10 % sucrose) can facilitate learning a subsequent hard discrimination (4 % and 7 % sucrose) when one of those flavors is paired with illness. Experiment 1A compared the effects of preexposure to the easily discriminated flavors against exposure to the same stimuli used in the discrimination training or no exposure at all. Experiment 1B replicated the conditions in Experiment 1A, with 2 additional days of training and unrestricted access to the flavors on CS+/CS– trials in discrimination training. Contrary to findings with multidimensional stimuli (Scahill & Mackintosh, Journal of Experimental Psychology: Animal Behavior Processes, 30, 96–103, 2004; Suret & McLaren, The Quarterly Journal of Experimental Psychology, 56B, 30–42, 2003), we found that preexposure to the easily discriminable stimuli varying along a single dimension of sweetness facilitated subsequent discrimination training over the other conditions in each experiment. We discuss the results in terms of the ideas presented by Gibson (1969) and Mackintosh (Psychological Review, 82, 276–298, 1975) and in terms of hedonic variables not considered by theories of perceptual learning.     

One School, Many Differences: An Assessment Tool for School Counselors and Multicultural Counseling

Multicultural counseling competencies (MCCs) have typically been measured with instruments designed for and normed on mental health professionals – for example, MCCTS-R; Holcomb-McCoy (Professional School Counseling 4:195–208, 2001); MCI; Sodowsky et al. (Journal of Counseling and Development 41:137–148, 1994); D’Andrea et al. (Journal of Counseling & Development 70:143–150, 1991). One published instrument specifically assesses school counselor MCCs – MCCTS-R; Holcomb-McCoy (Professional School Counseling 4:195–208, 2001) – but it does not conform to ASCA standards (2010, E.2). Following a set of validation procedures, an instrument designed to specifically assess school counselors’ multicultural counseling competencies was created that conforms to American School Counselor Association and Association for Multicultural Counseling and Development standards. Its creation is detailed here and the resulting instrument is presented for examination and consideration.     

“Jesus Loves Me, This I Know”: Finding a Rainbow God in Contemporary Adolescent Literature

This article explores four adolescent novels published between 1999 and 2010 specifically for the intersections of Christian faith and lesbian and gay sexual identities. Using cultural, queer, and ideological theories, the piece makes distinctions between progressive and traditional depictions of both Christianity and LGBTQ teen protagonists in Nancy Garden’s The Year They Burned the Books (1999), Laura Torres’s November Ever After (1999), Alex Sanchez’s The God Box (2007), and Mark Hardy’s Nothing Pink (2008).
