Advancing students’ computational thinking skills through educational robotics: A study on age and gender relevant differences

This work investigates the development of students’ computational thinking (CT) skills in the context of educational robotics (ER) learning activity. The study employs an appropriate CT model for operationalising and exploring students’ CT skills development in two different age groups (15 and 18 years old) and across gender. 164 students of different education levels (Junior high: 89; High vocational: 75) engaged in ER learning activities (2 hours per week, 11 weeks totally) and their CT skills were evaluated at different phases during the activity, using different modality (written and oral) assessment tools. The results suggest that: (a) students reach eventually the same level of CT skills development independent of their age and gender, (b) CT skills in most cases need time to fully develop (students’ scores improve significantly towards the end of the activity), (c) age and gender relevant differences appear when analysing students’ score in the various specific dimensions of the CT skills model, (d) the modality of the skill assessment instrument may have an impact on students’ performance, (e) girls appear in many situations to need more training time to reach the same skill level compared to boys.     

The learning value of computer-based instruction of early reading skills

Abstract This study examined the unique contribution of computer-based instruction when compared with more conventional modes of instruction (i.e. teacher instruction with textbooks) to early reading skills acquisition, as well as the effects of specific features of computer technology on early reading skills performance. Forty-six pre-school children (aged 5–6), at high risk for learning disabilities, participated in the study. They were assigned to one of three study groups that received different treatments. Three dependent variables were defined, i.e. children's phonological awareness, word recognition and letter recognition skills measured prior and after the treatment. Results clearly indicated that children at high risk who received the reading intervention program with computer materials significantly improved their phonological awareness, word recognition, and letter naming skills relative to their peers who received a reading intervention program with only printed materials and those who received no formal reading intervention program. The results are discussed in detail, with reference to the features of the computer-based materials that contributed to the acquisition of critical early reading skills.     

Which way of design programming activities is more effective to promote K-12 students' computational thinking skills? A meta-analysis

Promoting the cultivation of computational thinking (CT) skills in programming activities has become a key issue in the K-12 curriculum, however, there is no unified conclusion on how to design programming activities to promote the acquisition of CT skills more effectively. The purpose of this study is to determine the effectiveness of using programming to enhance K-12 students' CT skills and explore the influence of various programming instructional design factors on the acquisition of CT skills. This study presents a quantitative meta-analysis. A systematic search of randomized controlled studies on the influence of programming on CT skills. A total of 86 empirical studies with 114 effect sizes met the study selection criterion. The results showed that programming improved K-12 students' CT skills in general (Hedges' g = 0.601, 95% CI [0.505, 0.697], p < 0.001). No publication bias was detected. Besides, we found that the interdisciplinary integration of programming, the duration of programming intervention within 1 week to 1 month, the class size of less than 50 students, and a reasonable selection of programming instruments and CT assessment types may be more conducive to promoting students' CT skills. Based on these findings, we suggest that programming instructional design should be planned reasonably to make the best use of technology towards developing students' CT skills. This will be of great significance to programming teaching and CT education in K-12.     

Combining teacher-Led and technology-assisted instruction to improve phoneme blending to read words for elementary students with disabilities

Technology-assisted instruction has potential for helping students improve their reading skills. In the current studies, PowerPoint software was used to supplement teacher-led reading instruction for elementary-aged students with disabilities who struggled with phoneme blending to read words. The effectiveness of the intervention was assessed using two multiple probe design studies across sets of words based on an onset-rime (word family) strategy. In Study 1, teacher-led instruction was paired with technology-assisted instruction for all intervention sessions for three students in first and second grade. In Study 2, teacher-led instruction occurred between baseline and technology-assisted intervention sessions for three students in third and fourth grade. During the initial instruction sessions, participants recorded their own voices onto PowerPoint slides so that their technology-assisted instruction included self-modelling. Results of both studies indicated that technology-assisted instruction can be effective for helping students learn how to blend phonemes to read words; however, performance varied and there were limitations in each study that should be addressed in future research. Relevant implications for classroom instruction are emphasized.     

A co-creation blended KM model for cultivating critical-thinking skills

Both critical thinking (CT) and knowledge management (KM) skills are necessary elements for a university student’s success. Therefore, this study developed a co-creation blended KM model to cultivate university students’ CT skills and to explore the underlying mechanisms for achieving success. Thirty-one university students participated in this study. Findings from the 17-week training program suggest that scaffolding university students through knowledge sharing, internalization, and co-creation processes in a blended KM environment can effectively enhance their CT skills. Moreover, the attribute–treatment interaction (ATI) analysis suggests that judicial thinking style which relates to a deep learning approach may facilitate KM and help improve CT skills. Notably, the complex underlying mechanisms and paths of influence found in this study attest to the highly dynamic nature of the proposed KM processes.     

Applying online externally-facilitated regulated learning and computational thinking to improve students’ learning

This study aims to explore, via quasi-experiments, the effects of online externally-facilitated regulated learning (ERL) and computational thinking (CT) on improving students’ computing skills in a blended learning environment. Four classes in a one-semester course entitled ‘Applied Information Technology: Data Processing’ were the samples for this research. The first class (C1, ERL&CT group) simultaneously received the interventions regarding online ERL and CT, the second class (C2, CT group) received the intervention regarding online CT, and the third class (C3, ERL group) received the intervention regarding online CT, while the last group (C4, control group) received a traditional teaching method, although teaching was also conducted in a blended computing class. Students in ERL&CT group and CT group came from the Department of Finance, while the ERL group and control group came from the Department of Law at a comprehensive university. According to the posttest analysis, the results indicate that students who received the intervention of online ERL had statistically better development of computing skills for using Excel by semester-end than those without. In addition, this study also reveals that the application of online CT alone could be helpful in students’ development of computing skills. Furthermore, the results indicate that students’ computing skills could be improved under the condition of simultaneously applying ERL and CT. Based on the findings of this study, the authors present implications for online teachers and educators, particularly for those teaching computing courses.     

Effectiveness of MMORPG‐based instruction in elementary English education in Korea

This study investigated the effectiveness of massive multiplayer online role‐playing game (MMORPG)‐based (massive multiplayer online role‐playing game) instruction in elementary English education. The effectiveness of the MMORPG program was compared with face‐to‐face instruction and the independent variables (gender, prior knowledge, motivation for learning, self‐directed learning skills, computer skills, game skills, computer capacity, network speed, and computer accessibility) were examined to see how accurately achievement was predicted in MMORPG instruction. The results indicated that students studying English utilizing online role‐playing games showed higher scores in areas of listening, reading, and writing than those who attended face‐to‐face instruction classes. It was also found that prior knowledge, motivation for learning, and network speed were factors affecting achievement in English learning. These findings suggest that MMORPGs can play an important role in improving English communicative skills.     

Interactive augmented reality system for enhancing library instruction in elementary schools

Due to limited budgets and manpower, most elementary schools in Taiwan do not plan or provide library instruction for students. Although students can use libraries, they typically lack the knowledge needed to use library resources effectively. Consequently, students have difficulty finding the books they need and can easily become overwhelmed by the massive amount of information in libraries. Computer-assisted instruction for teaching basic library skills to large numbers of students is an appealing method. Particularly, developing augmented reality (AR) technologies for learning have garnered considerable attention in education research. Many researchers and scholars believe that integrating teaching and AR enhances student learning performance and motivation. This work develops an educational AR system based on situated learning theory, and applies innovative augmented reality interactive technology to a library’s learning environment. Student library knowledge can be enhanced via the proposed augmented reality library instruction system (ARLIS). Experimental results demonstrate that student learning performance is improved significantly by using the proposed ARLIS. Moreover, this work demonstrates that using the proposed ARLIS for library instruction results in the same learning performance as conventional librarian instruction and there is no gender difference on learning performance between the proposed ARLIS and conventional librarian instruction. Moreover, the proposed library instruction system overcomes shortcomings of personal teaching skills of librarians that may adversely affect student learning performance by conveying the same learning content to all students. Additionally, the proposed system results in better learning performance for learners with the field-dependent cognitive style than learners with the field-independent cognitive style. Further, the proposed system provides more benefits in terms of library skills of application and comprehension than conventional librarian instruction. Moreover, the learning performance of students is not affected by their gaming skills. Therefore, student gaming skills do not need to be considered when adopting the proposed system in library instruction programs.     

The impact of adaptive computer assisted instruction on reading comprehension: Identifying the main idea

Research has demonstrated that computer assisted instruction (CAI) can have positive impacts on various literacy skills, however its impact on specific comprehension skills is currently unclear. This study employed a small-scale randomized control trial to examine the impact of a researcher-developed adaptive computer assisted instructional program, Digital Comprehension, on 47 upper elementary struggling readers' comprehension skills, specifically main idea identification. Students were randomly assigned to treatment and control groups, with students in the treatment group engaging in the Digital Comprehension program and students in the control group receiving only business-as-usual classroom instruction. Students completed measures assessing main idea and general reading comprehension skills at pre- and post-intervention. Students in the treatment group demonstrated statistically significant greater growth in main idea skills than students in the control group. No main effect for the intervention was found for general reading comprehension skills, although there was a significant interaction between condition and student's pretest scores. Results indicate that adaptive CAI may be an effective means for remediating struggling readers' main idea skills.     

Modeling complex marine ecosystems: an investigation of two teaching approaches with fifth graders

Abstract  This study investigated acquisition and transfer of the modeling ability of fifth graders in various domains. Teaching interventions concentrated on the topic of marine ecosystems either through a modeling-based approach or a worksheet-based approach. A quasi-experimental (pre–post comparison study) design was used. The control group ( n  = 17) received a traditional worksheet-based instruction about ecosystems, whereas the experimental group ( n  = 16) received an instruction which was based on Stagecast Creator, an object-oriented programming tool, and a set of modeling-based curriculum materials. Paper-and-pencil tests were used both before and after the study to evaluate students' development of specific modeling skills. The data analysis followed both qualitative and quantitative methods. The findings of the present study indicate that (i) the development of modeling ability was effectively enhanced through the modeling-based approach, since, after instruction, students were able to transfer those aspects to unfamiliar contexts; in contrast, the more traditional worksheet-based approach did not promote the development of the same aspects of the modeling skill; and (ii) Stagecast Creator enabled students to construct, test, revise and validate dynamic computer-based models of a marine ecosystem through building, testing and debugging complex rules, routines and programs for simulating multiple behaviours and processes of marine species.     

Effects of simulation‐based learning on students' statistical factual,conceptual and application knowledge

The purpose of this study was to (1) examine the effects of a storyline on learners' factual, conceptual and application knowledge with the use of a simulation for teaching introductory statistical skills and to (2) explore students' subjective enjoyment of various learning activities often used in statistics education. In order to conduct the study, two versions of a simulation were developed that differed in the presence or absence of a storyline attribute. Sixty‐four graduate students were randomly assigned to one of the two intervention conditions. Both intervention groups demonstrated significantly higher learning gains after interacting with the simulation. Particularly, both simulation‐based interventions had a positive significant effect on the acquisition of application knowledge and skills. However, no significant differences between the intervention groups on any learning outcome explored in the study were found. Results also showed that students rated the simulation used in the study as a more enjoyable learning activity in comparison to reading a textbook, lecture or teamwork. Students from the simulation without a storyline intervention reported higher enjoyment than the other intervention group. Implications of the findings for understanding the instructional benefits and shortcomings of embedding a storyline in digital learning content are discussed.     

Developing a web‐based multimedia assessment system for facilitating science laboratory instruction

This study developed a web‐based multimedia assessment system (WMA system) and applied it to science laboratory instruction. The goal was to improve students' knowledge acquisition under science laboratory instruction. The developed system enabled learners to perform self‐assessments by responding to multimedia technology test items online. The system recorded each learner's complete answer history and provided the students with personalized learning resources. This study adopted a quasi‐experimental research design. The learning content was an “experiment on separating mixtures.” Students participating in the research were divided into a typical science laboratory instruction group (TI group; n = 25) and a group that received instruction through the WMA system (WMA group; n = 26). Before instruction, all the students completed the conceptual knowledge and experimental knowledge pretests. During instruction, the TI group watched the teacher's demonstration experiment, and the students then performed the experiment in a real laboratory. In the WMA group, after learning through the WMA system, the students also performed the experiment in a real laboratory. After instruction, all the students completed the conceptual knowledge and experimental knowledge posttests. The findings indicated that the students in the WMA group showed significantly higher improvements in their scientific conceptual knowledge and experimental knowledge.     

Designing a powerful learning environment to promote durable conceptual change

The purpose of this study was to investigate the long-term effectiveness of a three-dimensional (3D) computer modeling supported predict–observe–explain (POE) strategy on pre-service science teachers' understanding of lunar concepts. Thirty-three preservice teachers participated in the study. A questionnaire was used to assess participants' understanding of the phases of the Moon and eclipses before, after, and 22 months after the instruction. Semi-structured interviews were conducted with six participants before and after the instruction. The results demonstrated that few participants had a scientific understanding about the targeted lunar concepts before the instruction. However, the majority of the participants had a scientific understanding after the instruction indicating that the instructional intervention was quite effective in facilitating conceptual change. The results also demonstrated that twenty-two months after the instruction most participants maintained their scientific conceptual understanding suggesting that the powerful learning environment designed for this study was effective in promoting a durable conceptual change.

iPad-assisted reading fluency instruction for fourth graders with reading difficulties: A single case experimental design

The purpose of this study was to investigate the effect of iPad-assisted reading instruction for fourth-grade students' oral reading fluency and their attitudes towards reading. Three fourth-grade students at-risk for reading disabilities participated in an iPad-assisted repeated reading programme that integrated repeated reading, vocabulary instruction, error correction and feedback procedures. During each intervention session, the participants practiced reading a fourth grade-level text, engaged in repeated reading with the intervention agent and repeatedly read the text three or four times with error correction. The oral reading rate for the fourth-grade text that they practiced and a transfer text (i.e., new text that students have not practiced before) served as the primary dependent variables. Their attitudes towards reading were measured before and after the intervention. Using a multiple baseline across participants design, we showed that the iPad-assisted repeated reading programme improved all participants' oral reading rates on both the grade-level text and the transfer text. Implications of the study and future directions were discussed.     

Enhanced recognition of written words and enjoyment of reading in struggling beginner readers through whole-word multimedia software

The effectiveness of a reading intervention using the whole-word multimedia software ‘Oxford Reading Tree (ORT) for Clicker’ was compared to a reading intervention using traditional ORT Big Books. Developing literacy skills and attitudes towards learning to read were assessed in a group of 17 struggling beginner readers aged 5–6 years. Each child was given each of the two interventions, and the order of intervention was counterbalanced across the group. Each intervention was integrated into the literacy hour over five consecutive days. Measures of written word recognition, written word naming, phonological awareness and attitudes towards computers were taken before and after each intervention. Significant gains in performance were found following both interventions for all of the literacy measures, but significantly greater gains in written word recognition and enjoyment of instruction were found following the Clicker than Big Book intervention. These results suggest that whole-word multimedia software could be a useful classroom aid for supporting early literacy skills in children who are struggling with learning to read.     

Learning multiplication through computer-assisted learning activities

This study develops and implements a computer-assisted learning (CAL) program with both multiplicative facts practices and the instruction of meaning behind these facts. The effectiveness of CAL on the development of multiplication abilities is also explored. Eight CAL activities are developed to teach multiplication to second grade elementary school students. The CAL program is comprised of three stages of instruction that addressed in succession the basic concept of multiplication, the meaning and properties of multiplication and multiplication-related computation skills. Evaluation of the effects of the learning activities reveals that CAL activities are effective in improving comprehension of the concept of multiplication and the meaning and properties of multiplication for students who have lower prior knowledge of multiplication, but it does not significantly improve the development of multiplication-related computation skills. Nevertheless, CAL activities facilitate overall learning of multiplication.     

Completion strategy or emphasis manipulation? Task support for teaching information problem solving

While most students seem to solve information problems effortlessly, research shows that the cognitive skills for effective information problem solving are often underdeveloped. Students manage to find information and formulate solutions, but the quality of their process and product is questionable. It is therefore important to develop instruction for fostering these skills. In this research, a 2-h online intervention was presented to first-year university students with the goal to improve their information problem solving skills while investigating effects of different types of built-in task support. A training design containing completion tasks was compared to a design using emphasis manipulation. A third variant of the training combined both approaches. In two experiments, these conditions were compared to a control condition receiving conventional tasks without built-in task support. Results of both experiments show that students' information problem solving skills are underdeveloped, which underlines the necessity for formal training. While the intervention improved students’ skills, no differences were found between conditions. The authors hypothesize that the effective presentation of supportive information in the form of a modeling example at the start of the training caused a strong learning effect, which masked effects of task support. Limitations and directions for future research are presented.     

Improving diagrammatic reasoning in middle school science using conventions of diagrams instruction

Visual representations are essential for science understanding, but many students have poor diagrammatic reasoning skills. Previous research showed that teaching high school and college students about the conventions of diagrams (COD) can improve diagrammatic reasoning. In this study, middle school science students received COD instruction delivered as a classroom warm‐up using laptop computers, while control students received publisher‐developed warm‐up questions. Students receiving COD warm‐ups for 10 weeks (but not 4 weeks) improved their diagrammatic reasoning more than control students. Treatment students' answers were more accurate than control students' answers, especially on easy questions. The discourse of pairs of students during the warm‐ups showed that treatment students talked about the diagrams more and made more inferences and that this difference was greatest for easy questions. Results suggest that COD instruction can be initiated in middle school along with more formal science instruction, can be integrated into classroom routine using computer‐delivered warm‐ups, is helpful (if sustained) both for improving diagrammatic reasoning and for supporting learning science content and works at least in part by increasing students' engagement during routine work.     

Evaluation of the Efficacy of Affective Education Online Training in Promoting Academic and Professional Learning and Social Capital

This study aimed to compare the efficacy of face-to-face and online education seminars in the professional training of psychology majors and in promoting the development of social capital. Forty-four university students, balanced by gender, age, and academic achievement were divided in two groups, online and face to face, taught by the same teacher. Individual learning scales were administered and students were tested on group processes tasks to measure professional skills acquisition. A follow-up interview 9 months after the end of the seminar was undertaken to assess whether social bonds, formed during the seminars, had lasted over time. An analysis of variance and Mann-Whitney test were used to analyze the data. Results show that students of both groups increased their academic knowledge and social capital, but Computer Supported Collaborative Learning students acquired more group observation skills.
