Design-based research methodology was used to guide a line of research to develop, implement, revise, and evaluate the ESCOLAR online science curriculum for middle school students, including general education students, English language learners (ELs) primarily of Hispanic origin, and students with high-incidence learning disabilities (LD). The iterative research approach was carried out in three stages with multiple steps per stage: (1) Stage 1, or informed exploration, identified and described the problem under investigation; (2) Stage 2, or enactment, redesigned previously developed online science units, implemented each unit in case studies, and completed a feasibility evaluation; and (3) Stage 3, or evaluation of local impact, documented the efficacy of the science curriculum with a randomized controlled trial. The present chapter focuses on the second and third stages, demonstrating the process by which the ESCOLAR curriculum was repeatedly refined with input from stakeholders, and then examined for feasibility of implementation, usefulness in helping teachers engage with students, and efficacy in deepening student science knowledge. Data were drawn from multiple sources, including teacher logs, student and teacher surveys, web analytics, student notebooks, content assessments, and focus groups. Results indicate that the ESCOLAR curriculum was feasible to implement, useful, and effective, and may now be adopted as an evidence-based intervention to enhance science learning among diverse students. The data-driven, design-based research methodology proved to be a practical framework, and underscored the critical importance of considering all stakeholders in the process of curriculum design, refinement, and evaluation. This chapter offers a model for the development of constructivist science instructional materials for ELs and students with LD using online, multimedia technology.

This article reports on how design-based research methodology was used to guide a line of intervention research that developed, implemented, revised, and evaluated online learning science curricula for middle school students, including general education students and English language learners (primarily of Hispanic origin). The iterative, design-based research approach was carried out in two stages with multiple steps per stage: (a) stage 1, or informed exploration, identified and described the problem under investigation; and (b) stage 2, or enactment, redesigned previously developed online science units, implemented each unit in case studies, and completed a feasibility evaluation. The present paper focuses primarily on the second stage, demonstrating the process by which online science units were repeatedly refined with input from stakeholders, and then examined for their feasibility to implement, usefulness for helping teachers engage with students, and potential to effectively deepen science knowledge. Data were drawn from multiple sources, including teacher logs, student and teacher surveys, student notebooks, content assessments, and focus groups. Results indicate that the online science units were feasible to implement, usable, and helpful. The data-driven, design-based research methodology proved to be both practical and efficacious, and underscored the critical importance of involving all stakeholders in the process of curriculum creation and refinement. This work offers a model for the development of constructivist science instructional materials for English learners using online, multimedia technology.

Grounded in a design-based research approach, the aim of this article is to determine whether scientific evaluations help to (a) identify and fix problems in educational interventions and (b) eventually foster a more effective and positive evaluated intervention. Therefore, data from a longer-term evaluation of short digital simulation games about the European Parliament for civic education in schools were used. The data included three cycles of interventions with pre- and post-evaluations starting with the first prototype in 2015/2016 (n = 209), the second cycle in 2017/18 (n = 97), and the last one in 2019/20 (n = 222). After each evaluation, major problems and critiques regarding the simulation game were discussed with the developers, and changes were implemented in the game design. The four most important problems, the processes by which they were improved and the reactions of the participants in the following evaluations are pointed out in the article. A comparison of the last and first evaluation cycle showed an overall improvement of the simulation game regarding its effectiveness in transferring EU knowledge and the participants’ general satisfaction with the simulation game. This study underlines the value of the design-based research approach for developing educational interventions and can be useful for further work on civic education measures and the implementation of digital simulation games.

Big Data is gaining rapid popularity in e-commerce sector across the globe. There is a general consensus among experts that Saudi organisations are late in adopting new technologies. It is generally believed that the lack of research in latest technologies that are specific to Saudi Arabia that is culturally, socially, and economically different from the West, is one of the key factors for the delay in technology adoption in Saudi Arabia. Hence, to fill this gap to a certain extent and create awareness about Big Data technology, the primary goal of this research was to identify the impact of Big Data on e-commerce organisations in Saudi Arabia. Internet has changed the business environment of Saudi Arabia too. E-commerce is set for achieving new heights due to latest technological advancements. A qualitative research approach was used by conducting interviews with highly experienced professional to gather primary data. Using multiple sources of evidence, this research found out that traditional databases are not capable of handling massive data. Big Data is a promising technology that can be adopted by e-commerce companies in Saudi Arabia. Big Data’s predictive analytics will certainly help e-commerce companies to gain better insight of the consumer behaviour and thus offer customised products and services. The key finding of this research is that Big Data has a significant impact in e-commerce organisations in Saudi Arabia on various verticals like customer retention, inventory management, product customisation, and fraud detection.

The purpose of this study was to describe the voice change and voice part assignment of male middle school choir members. Volunteers ( N = 92) were recruited from three public middle school choral programs (Grades 6-8). Participants were audio-recorded performing simple vocal tasks in order to assess vocal range and asked to share the music they were currently singing in class. Results revealed 23.91% of participants’ voices could be categorized as unchanged, 14.13% as Stage 1, 3.26% as Stage 2, 10.87% as Stage 3, 26.09% as Stage 4, and 21.74% as Stage 5. The majority of sixth-grade participants were classified as unchanged or in Stage 1 of the voice change and the majority of eighth-grade participants were classified in Stages 4 to 5 of the voice change. Of the participants labeled “tenors” in their choir, over 60% were classified as either unchanged voices or in Stage 1 of the voice change.

Using a design-based research approach, we developed a data-rich problem (DRP) set to improve student understanding of cellular respiration at the ecosystem level. The problem tasks engage students in data analysis to develop biological explanations. Several of the tasks and their implementation are described. Quantitative results suggest that students from the experimental class who participated in the DRP showed significant gains on cellular respiration posttest items, and students from the control class who participated in a non-DRP task showed no significant gains. Qualitative results from interviews and written responses showed that students from the experimental class progressed to deeper “levels of achievement” in cellular respiration. The data-rich tasks promote student understanding of cellular respiration, matter transformation, decomposition, and energy transformation – all goals recommended by the Next Generation Science Standards.

Data-Driven Learning (DDL), or a corpus-based method of language teaching and learning, has been developing rapidly since the turn of the century and has been shown to be effective and efficient. Nevertheless, DDL is still not widely used in regular classrooms for a number of reasons. One of them is that few workable pedagogical frameworks have been suggested for integrating DDL into language courses and curricula. This chapter describes an exemplar of a practical application of such a pedagogical framework to a high-intermediate university-level German as a foreign language course with a significant DDL component. The Design-Based Research approach is used as the main methodological framework. The chapter concludes with a discussion of wider pedagogical implications.

Even experienced mountain climbers underestimate key dangers and make poor decisions in stressful, high-risk situations when climbing, leading to injury and death. My own experience indicates that effective education can play a key role in managing these risks and improving experienced climber’s decision making. Current educational approaches for climbers, however, are generally limited to textbooks and ‘on the mountain’ learning. It is vital, therefore, that new approaches and methods are developed to improve learning.    My own experience and emergent case studies indicate that AR (Augmented), VR (Virtual Reality) and MR (Mixed Reality), have affordances (possibilities offered by the technology) to underpin new forms of learning and therefore have the potential to enhance education for high-risk environments. Emergent use of MR immersive technologies includes classroom learning, firefighting and military training. An initial review of literature has indicated though that there are very limited examples of rigorous research on the design and application of MR technologies in authentic education, especially for extreme situations such as mountaineering i.e., no one has rigorously designed for these technologies for learning in extreme environments, evaluated learning outcomes and theorised about how learning can be enhanced.    In response to this gap/opportunity, this research explores the potential of MR technologies to effectively enhance learning for authentic, high-risk situations. The research will use a Design-based research methodology (DBR) to develop design principles informed by key learning theories as they offer recognised and critical approaches for a new way of learning in an extreme environment.  Underpinned by a Constructivist paradigm, initial theoretical frameworks identified include Authentic Learning and Heutagogy (student-determined learning).Herrington and co-authors (2009) recommended 11 design principles for the incorporation of mobile learning into a higher education learning environment, and Blaschke and Hase (2015)’s 10 principles of designing learning for heutagogy. Other theories and frameworks include Constructivist Learning and the ZPD (the Zone of Proximal Development), design for mobile MR learning and user-centred design. Activity Theory will also be utilised in the data analysis.   Initial design principles will be developed by the DBR methodology. These design principles will be tested through the implementation and evaluation of an MR ‘prototype’ app design solution.’ The prototype solution will be iteratively redesigned using further evaluation and feedback from sample cohorts of end-users. Data will be collected from key participant interviews, researcher observation/reflections and biometric feedback. Methodological triangulation (multimodal data approach) will be used to evaluate learning outcomes. The iterative development will lead to transferable design principles and further theorising that can be transferred to other learning situations involving preparation and decision-making as well as knowledge in high-risk contexts.    Reference   Amiel, T., & Reeves, T.

Introduction. The importance of memory is not restricted to remembering the knowledge and experiences of the past retrospective memory (RM), but also to remember what an individual must accomplish in the future prospective memory (PM). Objectives. The aim of this study was to identify RM and PM levels in students with learning disabilities (LD) according to some variables (gender, grade) and to identify the differences between the two types of memories. Methods. The study followed the comparative descriptive statistics. The study sample consisted of 37 male and female students with LD in middle school. The Prospective and Retrospective Memory Questionnaire (PRMQ) was used in this study. Results. The results include the following: a statistically significant decrease from the average in PM and RM levels in students with LD, the existence of statistically significant differences between PM and RM in students with LD for the RM, the presence of statistically significant differences in the PM and RM according to the gender variable for females, and the presence of statistically significant differences in PM and RM according to the grade variable for the third grade of middle school. Conclusion. Students with LD may suffer from a decrease in their capacity to remember in the future, which causes many difficulties in daily life. We guide teachers to use external AIDS for students with LD (such as writing notes) to help students remember performing their tasks.
