The effects of UZWEBMAT on the probability unit achievement of Turkish eleventh grade students and the reasons for such effects

This study aimed at determining the effects of UZWEBMAT (Turkish abbreviation of Adaptive and INtelligent WEB based MAThematics teaching–learning system) on the probability unit academic achievement of students and the underlying reasons for these effects. The study was conducted in an Anatolian High School located in a district of Trabzon province, Turkey in the fall semester of the academic year 2011–2012. The research sample consisted of 106 eleventh grade students and 2 mathematics teachers. Semi-experimental method was used in the study. Pre-Probability Unit Achievement Test (pre-PUAT), Post-Probability Unit Achievement Test (post-PUAT), Scale for Evaluation of the UZWEBMAT by Students (SEUS), Student Interview Form (SIF), and Teacher Interview Form (TIF) were used for collecting data. Research results indicated that there was a statistically significant difference in favor of the experimental group (EG) students between the academic achievement of the EG students and that of the control group (CG) students. In addition, male EG students were found to be more successful than female EG students. However, no statistically significant relationship was found between the learning styles and the academic achievements of the EG students with different learning styles (visual–auditory–kinesthetic). In addition, no statistically significant relationship was detected between the genders and the academic achievements of the EG students having different learning styles. It was concluded that the higher achievement of the EG students resulted from the fact that they received education in accordance with their learning styles via UZWEBMAT, the learning objects included in UZWEBMAT had appropriate structural characteristics, students enjoyed learning in that environment, and students had continuous interest in the lesson.     

The effects of learning style and hypermedia prior experience on behavioral disorders knowledge and time on task: a case-based hypermedia environment

This study involved 17 graduate students enrolled in a Behavioral Disorders course. As a part of the course, they engaged in an extensive case-based hypermedia program designed to enhance their ability to solve student emotional and behavioral problems. Results include: (1) students increased their knowledge about behavioral disorders; (2) those students with more hypermedia experience spent more time using the hypermedia program; (3) those students who acquired greater knowledge also wrote better student reports; and (4) students, regardless of learning style (as measured by Kolb's Learning Style Inventory), benefited equally from using the hypermedia program.     

Providing feedback on computer-based algebra homework in middle-school classrooms

Homework is transforming at a rapid rate with continuous advances in educational technology. Computer-based homework, in particular, is gaining popularity across a range of schools, with little empirical evidence on how to optimize student learning. The current aim was to test the effects of different types of feedback on computer-based homework. In the study, middle school students completed a computer-based pretest, homework assignment, and posttest containing challenging algebraic problems. On the homework assignment, students were assigned to different feedback conditions. In Experiment 1 (N = 103), students received no feedback or correct-answer feedback after each problem. In Experiment 2 (N = 143), students received (1) no feedback, (2) correct-answer feedback, (3) try-again feedback, or (4) explanation feedback after each problem. For students with low prior knowledge, feedback resulted in better posttest performance than no feedback. However, students with high prior knowledge learned just as much whether they received feedback or not. Results suggest the provision of basic feedback on computer-based homework can benefit novice students’ mathematics learning.     

Students' perceptions of instructors' roles in blended and online learning environments: A comparative study

This study develops an instrument—the Online Instructor Role and Behavior Scale (OIRBS)—and uses it to examine students' perceptions of instructors' roles in blended and online learning environments. A total sample of 750 university students participated in this study. Through a confirmatory factor analysis, the OIRBS was validated in five constructs: course designer and organizer (CDO), discussion facilitator (DF), social supporter (SS), technology facilitator (TF), and assessment designer (AD). The results show that the five factor structures remained invariant across the blended learning and online learning. Both students in blended learning environments and students in online learning environments exhibited the greatest weight in the CDO dimension, followed by the TF and DF dimensions. In addition, students in the online learning environments scored higher in the DF dimension than did those in the blended learning environments.     

SCCR digital learning system for scientific conceptual change and scientific reasoning

This study reports an adaptive digital learning project, scientific concept construction and reconstruction (SCCR), that was developed based on the theories of Dual Situated Learning Model (DSLM) and scientific reasoning. In addition, the authors investigated the effects of an SCCR related to a “combustion” topic for sixth grade students conceptual change and scientific reasoning. An experimental research design including the Combustion Achievement Test (CAT), Scientific Reasoning Test (SRT) and Combustion Dependent Reasoning Test (CDRT) was applied for both experimental and conventional group students before, directly after, and after the sixth week of the research as pre-, post- and retention-test. Results indicated that the experimental group students significantly outperformed the conventional group students on both post- and retention- of CAT and CDRT scores. In addition, experimental group students performed better than conventional group students on the post-SRT scores. The success rate of conceptual change ranged from 70% to 100% for experimental group students for most web-based dual situated learning events. The nature of the scientific reasoning used by experimental group students mainly either made progression (PG) or maintain-correct (MTC) across most events from before to after web-based dual situated learning events. All of these results support the claim that students’ conceptual change their scientific reasoning ability can be promoted through an SCCR digital learning program.     

Developing a hands-on activity using virtual reality to help students learn by doing

This study combined virtual reality (VR) technology, the 6E (Engage, Explore, Explain, Engineer, Enrich, and Evaluate) model, and STEM (Science, Technology, Engineering, and Mathematics) education to develop a hands-on activity aimed at helping students to achieve “learning by doing.” The participants were 162 tenth-grade students, divided into the Experimental Group (hands-on activity using VR technology) and the Control Group (hands-on activity via lectures). Using sequential analysis, this study investigated how the hands-on activity influenced the students' behavioral patterns in learning. The results showed that all of the students' learning performances and hands-on abilities were enhanced. Moreover, the students who used VR technology achieved both significantly better learning performances and hands-on abilities, indicating that VR might be able to help the students understand abstract scientific concepts and build mental models, which they used to internalize and organize knowledge structures. Furthermore, this study discovered that the students who learned using VR technology formed a cyclical learning pattern, starting with a group discussion (G), moving on to solving problems (S) and developing a product (D), and then going back to another group discussion. However, the students who learned via lectures produced a linear learning pattern in the order of G→S→D.     

Internet ethics of adolescents: Understanding demographic differences

The current generation of adolescents, who are generally described as digital natives, have greater access to and are greater consumers of information than previous generations. However, adolescents are notably at-risk when they are confronted with ethical decisions since they may lack the necessary knowledge and experiences to discern and make the right decisions. This study investigated how the demographic variables of gender and socio-economic status (SES) influence the internet ethics of 825 Secondary 2 (Grade 8) students aged 11 to 16 in Hong Kong. Three unethical behaviours, namely, unauthorised acts (UNAC), internet stickiness (INST), and plagiarism (PLAG) were examined. Results revealed that male students tended to engage in more unethical behaviours than did female students. Also, students from low SES families tended to behave more unethically than did students from high SES families. Implications for educators and researchers are discussed with reference to the four component model of moral behaviour, which has been widely used to articulate internal psychological processes including moral sensitivity, moral judgement, moral motivation, and implementation that are commonly found in all moral acts.     

Who needs to do what where?: Using learning management systems on residential vs. commuter campuses

Learning Management Systems (LMS) are web-based systems allowing instructors and/or students to share materials and interact online. This study compared differences in LMS use between instructors and students at a large residential campus with students at a smaller commuter campus. Responses to an online survey about LMS activities and tools were categorized by three different interaction types: Learner–Instructor (LI), Learner–Content (LC), and Learner–Learner (LL). Aggregated log data was also analyzed to see if students’ use was consistent with their beliefs. Respondents from both campuses rate highly all activities and tools within the LMS. Findings suggest that residential students value activities and tools supporting LC interaction more than commuter students, while commuter students value activities and tools fostering LL interactions more than residential students. The aggregated log data was consistent with the survey data showing a higher level of activity in the most heavily used LC-oriented tools for the residential campus and higher activity in the LL-oriented tools for the commuter campus.     

How to improve the peer review method: Free-selection vs assigned-pair protocol evaluated in a computer networking course

This study provides field research evidence on the efficiency of a “free-selection” peer review assignment protocol as compared to the typically implemented “assigned-pair” protocol. The study employed 54 sophomore students who were randomly assigned into three groups: Assigned-Pair (AP) (the teacher assigns student works for review to student pairs), Free-Selection (FS) (students are allowed to freely explore and select peer work for review), and No Review (NR) (control group). AP and FS student groups studied and reviewed peer work in the domain of Computer Networking, supported by a web-based environment designed to facilitate the two peer review protocols. Our results indicate that students following the Free Selection protocol demonstrate (a) better domain learning outcomes, and (b) better reviewer skills, compared to the AP condition. Overall, the study analyzes the benefits and shortcomings of the FS vs AP review assignment protocol, providing evidence that the FS condition can be multiply beneficial to students who engage in peer review activities.     

Designing CALL for learning Chinese characters

Abstract Despite the enormity of its quantity, printed or written forms of Chinese characters are composed from a limited number of common components. For example, the characters for pond( ), lake( ), stream( ), river( ), sea( ) and ocean( ) all contain a component in common, a three-dot component representing water. When this clue is explicitly highlighted to students, the learning of Chinese characters can be greatly enhanced. Using a computer to help students to develop this kind of structural awareness about language learning has not yet been thoroughly examined. This paper reports on the design of CALL software based on a pedagogic method which helps students to develop the higher order skills to analyse and categorise Chinese characters by using components. The result of the classroom experiment has shown supportive evidence on the feasibility and the need of integrating the software with an affective and contextual way of teaching Chinese characters.
