Examining Instructional Design Principles Applied by Experienced Designers in Practice

There has been ongoing debate regarding the efficacy of teaching instructional design models to novice designers given that experienced instructional designers often use principles and adapted models when they engage in the instructional design problem‐solving process. This study utilized the Delphi technique to identify a core set of guiding principles used by designers in their practice. The purpose of this study was (1) to examine and describe the principles that guided instructional designers’ practice and (2) to identify the extent to which participants’ frames of reference included components of the ADDIE instructional design model. Sixty‐one principles were ultimately identified (reached consensus among the Delphi panel members). Thirty‐two of the principles aligned with the primary components of the design process (e.g., analysis, design, development, and evaluation). Additional principles (n = 29) related to other characteristics of design such as communication, project management, and design characteristics.     

How social challenges affect children’s regulation and assignment quality in hypermedia: a process mining study

Metacognition and Learning - The present study investigated the extent to which 18 dyads in 5th and 6th grade, who experienced low levels of social challenge, differed from 12 dyads who experience...     

School evolution: scientist-practitioner educators creating optimal learning environments for all students

Similarities and differences between discursive practitioners and scientist-practitioners are discussed in reference to a variety of issues. The scientist-practitioner's approach to generating and evaluating new knowledge is illustrated with two partnerships: (a) between the University of Washington Multidisciplinary Learning Disability Center and a school district (at-risk first graders in the Los Angeles Unified School District) and (b) between the University of Washington Literacy Trek Project and a local school (at-risk second graders in Seattle public schools). Both partnerships involved mostly children who were English language learners. These partnerships also illustrated how Vygotsky's approach to fostering cognitive development through social interaction can be integrated with that of his pupil Luria, who assessed the neuropsychological processes of the individual mind/brain. The most effective instruction for school-age children, who exhibit biological and cultural diversity, takes into account individual and social-cultural variables.     

Linking reform-oriented experiences to teacher identity: The case of an elementary mathematics teacher

Novice teachers often have difficulty transferring what they learn in teacher education programs to classroom practice. This is especially true for elementary school teachers who are expected to teach mathematics with reform-oriented methods. The purpose of this longitudinal case study was to examine the experience of one novice elementary school teacher over a 3-year period, and understand the factors that supported her to enact a reform-oriented practice in mathematics as she transitioned from being a preservice to inservice teacher. Influential mathematics education models, her commitment to learning, and school-based contexts affected her teaching identity and practices. To conclude, an argument is made for teacher education experiences to explicitly address mathematics teacher identity to support the enactment of reform-oriented practices.     

Comparing Multidimensional and Unidimensional Proficiency Classifications: Multidimensional IRT as a Diagnostic Aid

This research examined the effect of scoring items thought to be multidimensional using a unidimensional model and demonstrated the use of multidimensional item response theory (MIRT) as a diagnostic tool. Using real data from a large-scale mathematics test, previously shown to function differentially in favor of proficient writers, the difference in proficiency classifications was explored when a two-versus one-dimensional confirmatory model was fit. The estimate of ability obtained when using the unidimensional model was considered to represent general mathematical ability. Under the two-dimensional model, one of the two dimensions was also considered to represent general mathematical ability. The second dimension was considered to represent the ability to communicate in mathematics. The resulting pattern of mismatched proficiency classifications suggested that examinees found to have less mathematics communication ability were more likely to be placed in a lower general mathematics proficiency classification under the unidimensional than multidimensional model. Results and implications are discussed.     

Historical Views on the Origins of Korea’s Taekwondo

Abstract

The present study reviews the key contents and issues of Traditionalism, New Traditionalism and Revisionism, the key historical views of Taekwondo, with the purpose of focusing on the validity and limitations of New Revisionism. Traditionalism emphasizes that Taekwondo is Korea’s traditional martial art. New Traditionalism accepts this view and also recognizes the partial effect of Karate on Taekwondo without providing enough supporting evidence on their claims. Revisionism also focuses on the effect of Karate on Taekwondo. While New Revisionism shares a similar focus to Revisionism, it also focuses on the effects of Chinese martial arts on Karate and Taekwondo, which have been neglected previously. The validity of New Revisionism was supported with evidence on the following factors: the effect of Chinese martial arts on Karate, the effect of Chinese martial arts on Korea’s top five martial arts schools and their training methods, and the effect of Chinese martial arts appearing in the book written by the figures related to the top five initial martial arts schools after 1945. Despite a few limitations of the current historical views, New Revisionism suggests that Korea’s Taekwondo was affected by Japanese martial arts and Chinese martial arts, both directly and indirectly, in its formation.     

Systems learning with a conceptual representation: a quasi-experimental study

In this paper, we share results from a classroom intervention that used a conceptual representation to support reasoning about ecosystems. Engaging students in modeling allows them to make their ideas visible while being malleable and available for discussion, which enables students to make meaning out of systems. Further, the Components-Mechanisms-Phenomena (CMP) conceptual representation was designed to enable students to construct coherent mental models. Following our intervention, students deepened their understanding of ecosystem dynamics when compared to students who engaged in traditional instruction without use of the CMP conceptual representation. We discuss our results in terms of data that helped guide the design of the intervention and we describe a theoretical perspective that can be used to guide future instruction.
