Motivation of computer based learning across adulthood

This research investigates learning motivation of young and old adults. In detail, we explore motives of young and old adults to participate in two ICT-course settings: e-learning and face-to-face courses. In a first study young (n = 53, M = 26.0 years) and old (n = 55, M = 69.8 years) participants of e-learning courses completed an online questionnaire on learning motivation and personality. In a second study young (n = 46, M = 26.7 years) and old (n = 57, M = 69.5 years) participants of face-to-face ICT courses completed the same learning motivation questionnaire and questions about personality, subjective age and life satisfaction. Exploratory factor analysis revealed four factors of learning motivation: belonging, instrumentality, personal growth, and competition. As expected, older adults expressed stronger motives of belonging and personal growth, and thus expressed a stronger interest in self-determined and intrinsic learning. Young adults, in contrast, strongly endorsed competitive-related motives of learning. Instrumentality was influenced by the interaction of age and subjective age; older participants showed higher instrumentality when the difference between chronological age and subjective age is big. Findings of this study shed new light on assumptions of socioemotional selectivity theory.     

A study on e-learning take-up intention from an innovation adoption perspective: A case in China

This research aims to examine, from an innovation adoption perspective, Chinese students’ intention of taking up e-learning degrees. A survey of Chinese students was conducted to reveal their perceptions concerning innovation attributes relevant to e-learning and their intentions of taking e-learning programmes provided by UK universities. Given the rapid development in e-learning and its potential impact on how learning takes place, this research argues that e-learning take-up represents adoption of an innovation in educational services, rather than just an IT technology. It therefore examined e-learning adoption using Rogers’s relational model of perceived innovation attributes. Rogers’s model was adapted to the e-learning context. A questionnaire survey was developed to collect data from a sample of Chinese students (n = 215). Prior to final analysis the dimensionality and validity of the implementation of Rogers relational model was assessed. Findings suggested that only perceived compatibility and trialability have significant influence on e-learning adoption intention.     

Benefits of adding anxiety-reducing features to a computer-based multimedia lesson on statistics

The present study examined the effectiveness of techniques intended to reduce anxiety as students learn mathematical content from a computer-based lesson. In a between-subjects experiment, students learned statistical rules through worked examples in a computer-based learning environment that either did (treatment group) or did not (control group) include anxiety reducing features—a coping message delivered through the lesson by an online pedagogical agent concerning how to manage feelings of anxiety, and prompts for expressive writing, in which students summarize their thoughts and feelings. An independent samples t-test showed that the treatment group, which received added anxiety-reducing features, showed higher accuracy than the control group on solving practice problems (d = 0.71) and retention problems (d = 0.63) and reported higher perceived effort on learning the multimedia lesson (d = 0.66). In addition, a standard multiple linear regression found that anxiety, self-efficacy, and cognitive load as a set predicted performance (R² = 0.56), with self-efficacy as the strongest predictor (β = 0.63). Adding anxiety-reducing features to an online lesson may encourage greater effort, which leads to better learning outcomes.     

How can one amplify the effect of e-learning? An examination of high-tech employees’ computer attitude and flow experience

While numerous studies have focused on the effectiveness and benefits of e-learning, this study elicits the determinants of the IT professionals’ e-learning outcomes by investigating the effect of IT professionals’ computer attitudes on two personal outcomes: self-perceived flow experience and learning outcomes. Data collected from 50 technological companies which located in Hsinchu Science Parks in Taiwan (N = 239) were analyzed using structural equation modeling. Results confirm that both computer attitude and flow experience generate positive and direct influence on learning outcome. Specially, the effect of personal computer attitude is amplified on learning outcome through experience of flow in an e-learning environment. Managerial implications are proposed and research limitations are discussed.     

Investigating users’ perspectives on e-learning: An integration of TAM and IS success model

The purpose of this paper is to examine an integrated model of TAM and D&M to explore the effects of quality features, perceived ease of use, perceived usefulness on users’ intentions and satisfaction, alongside the mediating effect of usability towards use of e-learning in Iran. Based on the e-learning user data collected through a survey, structural equations modeling (SEM) and path analysis were employed to test the research model. The results revealed that “intention” and “user satisfaction” both had positive effects on actual use of e-learning. “System quality” and “information quality” were found to be the primary factors driving users’ intentions and satisfaction towards use of e-learning. At last, “perceived usefulness” mediated the relationship between ease of use and users’ intentions. The sample consisted of e-learning users of four public universities in Iran. Past studies have seldom examined an integrated model in the context of e-learning in developing countries. Moreover, this paper tries to provide a literature review of recent published studies in the field of e-learning.     

Cognitive consequences of making computer-based learning activities more game-like

Some students (base group) played the Circuit Game, a 10-level computer-based learning activity intended to help students learn how electrical circuits work. Other students (competition group) played the same game but with competition features added - including a score bar showing performance on each level, the opportunity to earn one ticket per level if a performance criterion is met, and the opportunity to win a prize based on the number of tickets earned. On a retention test given after the game, the competition group remembered significantly more than the base group (d = 0.47). On an embedded transfer test constituting the final level of the game, the groups did not differ significantly. However, on the transfer test there was a significant gender by group interaction in which men performed worse in the competition group than the base group (d = −0.54) and women performed better in the competition group than the base group (d = 0.24). Overall, adding game-like features to a computer-based learning activity caused students to pay attention to game details but did not motivate students - particularly men - to learn more deeply.     

Psychometric properties of the Problematic Internet Use Questionnaire

Several instruments have been designed to measure problems associated with excessive, compulsive, or addictive use of the Internet. One such instrument, the 18-item Problematic Internet Use Questionnaire, was recently published with data supporting a three subscale model (Demetrovics et al., 2008). These researches utilized an online format with a sample taken from the general population of Hungary. We utilized an American college student sample and a paper and pencil format to perform a confirmatory factor analysis of the PIUQ. In addition, we examined the reliability and construct validity of the PIUQ by examining the scales’ relationship with several indices of psychological and physical health. CFA results indicate a barely adequate and not completely problem free three factor model for the PIUQ (χ² = 477.40; root mean square error = .097; comparative fit index = .831; Tucker Lewis coefficient = .804). Cronbach’s α for the total scale was .91 while the Cronbach’s α for each subscale were .81, .77, and .79. Construct validity for the model is demonstrated with significant correlations between the subscales and several indices of psychological and physical health. Suggestions for further research are provided.     

Career HOPES: An Internet-delivered career development intervention

Career HOPES is an Internet-delivered group counseling intervention designed to facilitate occupational exploration and career decision making. The intervention includes automated interactive lessons and self-assessments, homework assignments, and group discussions in private online forums. A randomized, controlled experiment (N = 64) was conducted to evaluate (a) the efficacy of Career HOPES and (b) the contribution of professional moderation of the online group discussions to outcomes. Participants in two treatment conditions showed greater gains than control condition participants in career decidedness as measured by the Occupational Alternatives Questionnaire (d = .54), occupationally relevant self-knowledge (d = .58), and emission of career exploration behaviors (d = .50). In one of the treatment conditions, the online group discussions were moderated by a psychologist with career counseling experience; in the other treatment condition, the discussions were unmoderated. Professional moderation resulted in better outcomes on several variables and greater overall satisfaction with the intervention.     

The role of metacognitive listening strategies awareness and podcast-use readiness in using podcasting for learning English as a foreign language

The aim of this study was to investigate the role of English as Foreign Language (EFL) learners’ metacognitive listening strategies awareness and podcast-use readiness in using podcasting technology for learning English as a foreign language. One hundred and forty-one EFL students completed Metacognitive Awareness Listening Questionnaire (MALQ) that assessed their awareness and perceived use of listening strategies in five components including planning-evaluation, directed attention, person knowledge, mental translation, and problem solving. They also completed a questionnaire that assessed their readiness to use podcasting in terms of familiarity, attitude, and experience. Information on participants’ frequency of podcast use for learning English, frequency of the internet use, and digital device ownership was also obtained. The result of the analysis revealed that podcasting use was significantly related to metacognitive listening strategies awareness in general and its entire components except mental translation strategies while the strongest correlation was found with problem solving strategies (r = .49, p < 0.01). Podcasting use was also found to be significantly related to perceived podcast-use readiness and internet use hours. Further, multiple regressions showed that perceived podcast-use readiness, problem solving, and person knowledge -in order of power prediction- were good predictors of podcasting use for learning English as a foreign language.     

Enhancing a leaf radiative transfer model to estimate concentrations and in vivo specific absorption coefficients of total carotenoids and chlorophylls a and b from single-needle reflectance and transmittance

The relative concentrations of different pigments within a leaf have significant physiological and spectral consequences. Photosynthesis, light use efficiency, mass and energy exchange, and stress response are dependent on relationships among an ensemble of pigments. This ensemble also determines the visible characteristics of a leaf, which can be measured remotely and used to quantify leaf biochemistry and structure. But current remote sensing approaches are limited in their ability to resolve individual pigments. This paper focuses on the incorporation of three pigments—chlorophyll a, chlorophyll b, and total carotenoids—into the LIBERTY leaf radiative transfer model to better understand relationships between leaf biochemical, biophysical, and spectral properties.Pinus ponderosa and Pinus jeffreyi needles were collected from three sites in the California Sierra Nevada. Hemispheric single-leaf visible reflectance and transmittance and concentrations of chlorophylls a and b and total carotenoids of fresh needles were measured. These data were input to the enhanced LIBERTY model to estimate optical and biochemical properties of pine needles. The enhanced model successfully estimated reflectance (RMSE = 0.0255, BIAS = 0.00477, RMS%E = 16.7%), had variable success estimating transmittance (RMSE = 0.0442, BIAS = 0.0294, RMS%E = 181%), and generated very good estimates of carotenoid concentrations (RMSE = 2.48 µg/cm², BIAS = 0.143 µg/cm², RMS%E = 20.4%), good estimates of chlorophyll a concentrations (RMSE = 10.7 µg/cm², BIAS = − 0.992 µg/cm², RMS%E = 21.1%), and fair estimates of chlorophyll b concentrations (RMSE = 7.49 µg/cm², BIAS = − 2.12 µg/cm², RMS%E = 43.7%). Overall root mean squared errors of reflectance, transmittance, and pigment concentration estimates were lower for the three-pigment model than for the single-pigment model. The algorithm to estimate three in vivo specific absorption coefficients is robust, although estimated values are distorted by inconsistencies in model biophysics. The capacity to invert the model from single-leaf reflectance and transmittance was added to the model so it could be coupled with vegetation canopy models to estimate canopy biochemistry from remotely sensed data.     

The effects of video on cognitive load and social presence in multimedia-learning

Two studies examined the use of video in multimedia learning environments. In Study 1, participants (N = 26) viewed one of two versions of a computer-based multimedia presentation: video, which included a video of a lecture with synchronized slides, or no video, which included the slides but only an audio narration of the lecture. Learning, cognitive load and social presence were assessed, but a significant difference was found only for cognitive load, with video experiencing greater cognitive load, t (24) = 2.45, p < .05. In Study 2, students (N = 25) were randomly assigned to either video or no video condition. Background knowledge and visual/verbal learning preference were assessed before viewing the presentation, and learning, cognitive load, and social presence were assessed after viewing. No significant differences were found for learning or social presence. However, a significant visual/verbal learning preference by condition interaction was found for cognitive load, F (1,21) = 4.51, p < .05: low visual-preference students experienced greater cognitive load in the video condition, while high visual-preference students experienced greater cognitive load in the no video condition.     

Cognitive load and science text comprehension: Effects of drawing and mentally imagining text content

One hundred and eleven 10th graders read an expository science text on the dipole character of water molecules (ca. 1600 words). Reading instruction was varied according to a 2 × 2 experimental design with factors ‘drawing pictures of text content on paper’ (yes, no) and ‘mentally imagining text content while reading’ (yes, no). The results indicate that drawing pictures, mediated through increased cognitive load, decreased text comprehension and, thus, learning (d = −0.37), whereas mental imagery, although decreasing cognitive load, increased comprehension only when students did not have to draw pictures simultaneously (d = 0.72). No evidence was found that the effects were moderated by domain-specific prior knowledge, verbal ability, or spatial ability. The results are in line with cognitive theories of multimedia learning, self-regulated learning, and mental imagery as well as conceptions of science learning that focus on promoting mental model construction by actively visualizing the content to be learned. Constructing mental images seems to reduce cognitive load and to increase comprehension and learning outcome when the mental visualization processes are not disturbed by externally drawing pictures on paper, whereas drawing pictures seems to increase cognitive load resulting in reduced comprehension and learning outcome.     

Do students need teacher’s initiation in online collaborative learning?

As more and more people use computers to complete their work and solve problems in the workplace, computing education is emphasized for students of all levels and disciplines in Taiwan. However, the computing education in Taiwan can hardly be recognized as effective and satisfactory. Many inappropriate examples that lack context are used in teaching and textbooks that may result in employees with low competence and insufficient ability for collaborative working. Students who grow up in this learning context usually lack the ability to seek information and solve problems by themselves. In this regard, the author redesigned a course and adopted online collaborative learning with initiation to establish the essential knowledge for students’ collaboration in the initial stage of a course. This study conducted an experiment that included 169 undergraduates from three class sections – the first two from an academic university (Case 1, n = 68; Case 2, n = 68) and the last one from a university of science and technology (Case 3, n = 33) – taught by the same teacher under the same course name and the same course website. The results show that students who received online collaborative learning with initiation had higher grades than those without. The author further discusses the implications for teachers, schools, and scholars who plan to provide online courses for their students, particularly computing courses.     

The periodic nature of the positive solutions of a nonlinear fuzzy max-difference equation

We investigate the periodic nature of the positive solutions of the fuzzy difference equation , where k, m are positive integers, A₀, A₁, are positive fuzzy numbers and the initial values x_i, i = −d, −d + 1, … , −1, d = max{k, m}, are positive fuzzy numbers. In addition, we give conditions so that the solutions of this equation are unbounded.     

Construction of an instrument to measure student information and communication technology skills,experience and attitudes to e-learning

Over the past 20 years self-report measures of healthcare students’ information and communication technology skills have been developed with limited validation. Furthermore, measures of student experience of e-learning emerged but were not repeatedly used with diverse populations. A psychometric approach with five phases was used to develop and test a new self-report measure of skills and experience with information and communication technology and attitudes to computers in education. Phase 1: Literature review and identification of key items. Phase 2: Development and refinement of items with expert panel (n = 16) and students (n = 3) to establish face and content validity. Phase 3: Pilot testing of draft instrument with graduate pre-registration nursing students (n = 60) to assess administration procedures and acceptability of the instrument. Phase 4: Test–retest with further sample of graduate pre-registration nursing students (n = 70) tested stability and internal consistency. Phase 5: Main study with pre-registration nursing students (n = 458), further testing of internal consistency. The instrument proved to have moderate test–retest stability and the sub-scales had acceptable internal consistency. When used with a larger, more diverse population the psychometric properties were more variable. Further work is needed to refine the instrument with specific reference to possible cultural and linguistic response patterns and technological advances.     

Evaluation of a 3 year intervention to increase adoption of safer nursery crop production practices

Background

We conducted a 3 year intervention to increase awareness and adoption of eight more profitable nursery crop production practices that reduced certain traumatic and musculoskeletal injury hazards.

Methods

We disseminated information to nursery managers across seven states using information channels they were known to rely on (e.g. trade publications, public events, university Extension, other managers). We evaluated rolling, independent, probability samples (n = 1200) with mail questionnaires before the intervention and after each of 3 intervention years. We also evaluated samples (n = 250) from a comparison group of New Zealand nursery managers.

Results

The intervention was associated with increased awareness of four of the eight practices among US managers after year 3 compared to their baseline: zippers (20 vs. 32%, p ≤ 0.000), stools (11 vs. 22%, p ≤ 0.001), pruners (29 vs. 40%, p ≤ 0.014), and tarps (24 vs. 33%, p ≤ 0.009). There were no changes in adoption. New Zealand manager awareness was increased for hoes after year 2 compared to their baseline (35 vs. 52%, p ≤ 0.010).

Conclusions

A modest, regionwide information dissemination intervention was associated with increased awareness, but not adoption.     

Combined cognitive behavioral therapy and bupropion for the treatment of problematic on-line game play in adolescents with major depressive disorder

The purpose of the current study was to evaluate the efficacy of cognitive behavioral therapy (CBT) in combination with bupropion for treatment of problematic on-line game play in adolescents with co-morbid major depressive disorder. Sixty-five depressed adolescents with excessive on-line game play were randomly assigned to a CBT group (CBT-Med group (N = 32)) or a clinical control group (Med group (N = 33)). Measures of severity of internet use, depressive symptoms, anxiety symptoms, life satisfaction and school adaptation were assessed at baseline, after the 8 week intervention, and at the end of a 4 week follow-up post-treatment period. Young Internet Addiction Scale scores in the CBT-Med group were reduced compared to those of the Med group, but there was no significant difference in the change of depression scores between two groups. The mean anxiety scores in the CBT-Med group did not change while those in the Med group were increased. The mean life satisfaction scores in the CBT-Med group were increased compared to those of the Med group. CBT in combination with bupropion may be effective for the treatment of depressed adolescents with on-line game addiction, particularly in reducing on-line game play and anxiety, as well as in improving life satisfaction.     

Blending traditional teaching methods with learning environments: Experience,cyclical evaluation process and impact with MAgAdI

This paper reports the experiment carried out at the University of the Basque Country concerning the integration of the MAgAdI on-line system within traditional teaching/learning methods. MAgAdI is an adaptive web environment devoted to supporting the learning processes in overall contexts, in which several knowledge fields, courses and teachers are involved. So far, a three-year cyclical evaluation-improvement process has been developed on several subjects and participants (n = 80) of a Computer Science degree programme. This process embraced formative and summative evaluation phases with the aim of: discovering the implications of the blended-learning loop on the satisfaction of teachers and motivation of students confirming improvements in student learning; and testing the usability of the Student Workspace. Experimental data were collected by means of a combination of qualitative and quantitative methods. Results of this study detect improvements in the students' acquisition of knowledge in the three phases where it was evaluated (Wilcoxon-test, p = 0.02, p = 0.048, p = 0.044), which may be attributable to the use of MAgAdI. In addition, increments in student's motivation and teacher's satisfaction were also perceived. Thus, these results agree with previous findings of related works.     

Qualitative findings of students’ perception on practice of self-regulated strategies in online community discussion

With rapid emergence to the birth of the knowledge era, an active and interactive learning environment is fundamental to any teaching and learning process. Over time, negative implications of traditional learning environment are mounting, and measures must be taken to challenge it. With extensive research on available learning tools, it has become more feasible to provide our students with better learning opportunities. Such was the anticipation in the Malaysian educational context. Hence, this paper aims to address qualitative findings of a study on self-regulated learning strategies conveyed through the proposed interactive e-learning community (iELC). In duration of eight weeks, students (n = 50) from regular national secondary schools were subjected to online learning tasks aimed to advance strategies on self-regulated learning. To date, strategies of self-regulated learning have been perceived as key to learner to succeed academically and after the schooling years. By means of semi-structured interview, data were collected from small group and one-to-one perception. Results were directed at the overall development of self-regulated learning strategies and its diffusion in the iELC discussion platform. Conclusively, these findings add significantly to the understanding of self-regulated learning strategies in an online learning environment.
