The purpose of this study was to investigate secondary science teachers' PCK components and subcomponents that are specific to online and offline learning environment. Data collection consisted of survey, class observation, and individual interviews of twelve science teachers. This study used a theoretical framework of PCK for deductive data analysis and articulated codes and themes through the following inductive analysis. Data analysis revealed that each of PCK components showed different specificity to the online and offline learning environment. And subcomponents of each PCK component were different according to the specificity of the online and offline learning environment. Teaching orientation toward science had a specific orientation for the online learning environment, i.e., 'learning science concept' and 'lecture centered instruction.' Knowledge of the science curriculum had online-offline mixed learning environment specific knowledge, i.e., 'reorganization of curriculum' and online learning environment specific knowledge, i.e., 'development of learning goal' and 'science curricular materials.' Knowledge of science teaching strategies had online learning environment specific knowledge, i.e., 'topic-specific strategy', 'subject-specific strategy', and 'interaction strategy' and COVID-19 offline learning environment specific knowledge, i.e., 'topic-specific strategy' and 'interaction strategy'. Knowledge of student science understanding had online learning environment specific knowledge, i.e., 'student preconception', 'student learning difficulty', 'student motivation and interest', and 'student diversity' and COVID-19 offline learning environment specific knowledge, i.e., student learning difficulty'. Knowledge of science assessment had online-offline mixed learning environment specific knowledge and online learning environment specific knowledge, i.e., assessment contents and assessment methods for each.

The Internet is being utilized as a means of communication channel for science information. In this study, an experiment was conducted against college students, in which participants were assigned to one of the following four conditions: source status(professor, student) x social categorization(in-group, out-group). When the participants finished reading an online news article, perceived usefulness of and attitude toward the science technology were measured. The results show that the effect of source expertise on perceived usefulness was moderated by social categorization.

In this study, the user experience was analyzed from the learner's point of view, focusing on the metaverse platform 'Spatial'. SUS(System Usability Scale) was used to evaluate the usability of the metaverse platform 'Spatial' in a college class, and the Magnitude estimation technique was used to evaluate the immersion and satisfaction with the class. In addition, a questionnaire survey was used to collect user experience opinions on the use of 'Spatial' as a teaching tool. Looking at the usability evaluation results of the 'Spatial' system, the students evaluated the usability, immersion, and satisfaction quite positively. Looking at the user experience of metaverse platform 'Spatial', it was found that students highly valued Metaverse as an educational tool that can provide a place for many people to gather and communicate even in a non-face-to-face space. Compared to other online platforms, metaverse has advantages in ease of use, interaction, immersion, and interest. In particular, in addition to keyboard, touch, and display, interaction using the five senses such as voice, motion, and gaze was recognized as a great advantage. On the other hand, it was found that high openness, freedom, and interest factors can both promote learning and inhibit learning. Nevertheless, it is judged that the metaverse platform 'Spatial' can be effectively applied in college classes because it enables various interactions between instructor and learner or between learner and learner.

Using technology acceptance model, this study investigates the factors affecting N-screen service adoption. We collected 435 available answers from potential users through systematic online survey. Results show that self-efficacy and perceived interactivity factors had positive effects on perceived ease of use. In addition, service variety, perceived interactivity, perceived ease of use factors had positive effects on perceived usefulness. Yet social effect factor had negative effect on perceived usefulness. On the other hand, perceived ease of use and perceived usefulness had positive effect on the intention of use. In conclusion, to improve the intention to use N-screen service, it is necessary to make users convinced that N-screen service can give customized contents and interactive information regardless of time and place.

Under the influence of information technology, there has been a significant change in the consumers' attitude and behavior toward the cultural products. Especially, the social network service (SNS) is predicted to effectively facilitate the growing interaction among potential consumers, which may lead to consumption of the cultural products. The goal of this study is thus two-fold: (a) to investigate the characteristic features of the digital environments based on SNS, and (b) to examine how these factors result in the purchase of the cultural contents. The survey data identified the digital environments as Informational interaction, Information connectivity, and Informational trust in the SNS environment. Subsequently, the structural equation methods confirmed that these factors facilitate consumers' participation in the information network and promote consumers' emotional attachment to the cultural contents, which eventually lead to the positive attitude toward the purchase of the cultural contents.

The purpose of this study is to examine the effects of digital cultural contents characteristics, perceived values and perceived risks on customer satisfaction and purchase intentions for Chinese consumers, and contribute to the development of digital cultural contents. In addition, a total of 328 valid samples were obtained through an online survey and empirical analysis was conducted. The analysis results of the study are as follows. First, except for creativity, which are characteristics of digital cultural contexts, entertainment and interactivity also have a significantly positive effect on both customer satisfaction and purchase intention. Second, perceived value has a significant positive effect on customer satisfaction and purchase intention, whereas perceived risk does not have this significant effect. Third, customer satisfaction has a partial mediating effect between the three factors(entertainment, interactivity, perceived value) and purchase intention. Therefore, to promote the development of digital cultural contents, we could promote consumers' purchase behavior by improving satisfaction through content entertainment, communication between content producers and service providers, and unity and value that customers actually feel during the consumption process.
