This study investigated primary teachers’ knowledge of pronunciation instruction, and its manifestation in classroom practices in Korean EFL contexts. To this end, the questionnaire data collected from 47 teachers were quantitatively analyzed. The emerging themes from 5 teachers’ interviews were qualitatively analyzed, based on content analysis. Findings revealed that they had an appropriate knowledge base of pronunciation teaching, equipped with the better understanding of content knowledge (CK), followed by pedagogical content knowledge (PCK), and technical pedagogical content knowledge (TPACK). No statistically significant difference was found in teachers’ knowledge between males and females, and also between the 4 groups with different teaching experience. They manifested their knowledge mainly acquired from the past course lectures into classroom practices, employing controlled and free practices such as listening and repeating, shadowing, songs, chants, games, and role play, including different types of corrective feedback. Most notably, they integrated role play effectively into classroom practices to improve young learners’ pronunciation in interestprovoking and enjoyable ways.

The goal of this study was to examine the PCK required for science teachers and PCK required for university teacher educators in terms of school science knowledge, science teaching and learning, and the role of science educators, which are the main axes of science education in future schools, and to explore the relationship between them. This study is a follow-up to a previous stage of research that explored the prospects for changes in schools in the future (2040-2050) in terms of school knowledge, educational methods, and teacher roles. Based on in-depth interviews, qualitative and semantic network analyses were conducted to derive and compare the characteristics of PCK and PCK. As for the main research results, science teacher PCK in future schools should include expertise in organizing science classes centered on convergence topics, expertise in digital platforms and ICT use, and expertise in building a network of learning communities and resources, as part of the expertise of human teachers differentiated from AI. Teacher educators' PCK includes expertise in the research and development of T-L methods using AI, expertise in the knowledge construction process and practice, and expertise in developing preservice teachers’ research competencies. Discussed in the conclusion is the change in teacher PCK and teacher educator PCK with changes in science knowledge, such as convergence-type knowledge and cognition-value integrated knowledge; and the need to emphasize values, attitudes, and ethical judgments for the coexistence of humans and non-humans as school science knowledge in the post-humanism future society.

This study analyzes the research trends of PCK (Pedagogical Content Knowledge) in Korean English classes from 2005 to 2019 across ten journal articles, two master’s theses, two doctoral dissertations, and five research reports. This was intended to provide hints for the future direction of English PCK studies. Six criteria—subject-matter knowledge, pedagogical knowledge, learner knowledge, curriculum knowledge, social context knowledge, and action research knowledge— have been applied to the analysis of the selected English PCK studies. The findings are as follows. Study on the subject-matter knowledge was the most frequent, appearing in 15 studies, mainly dealing with linguistic knowledge. In the field of pedagogical knowledge, studies on class design were most common, and in the field of learner knowledge, learner background and learner characteristics were equally studied. In the social context knowledge field, there were relatively few studies on parents, and in the field of action research knowledge, the number of studies corresponding to three sub-factors was the same. Our study concludes that to systematize the study of PCK for teacher professionalism in the subject matter of English, English PCK education should be done in both pre-service and in-service institutions and that PCK research environments should be provided to this end.

This study investigated how pre-service English teachers develop and use MICT (mobile information and communication technology)-TPACK (technological pedagogy and content knowledge) to select and use mobile applications for their micro teaching in a pre-service teacher training program. Although mobile technology has rapidly developed with the adoption of mobile multimedia devices and applications, the use of pre-service teachers’ TPACK is still limited to lower-level searches and to a mere tool for content presentations. The participants were nine students in a pre-service teacher training course in a four-year women’s university. Several research methods such as surveys, participant observations, micro teaching and interviews were utilized. The results of the study show the concept of TPACK needs to be extended to MICT-TPACK in this mobile age. The use of pre-service English teachers’ MICT-TPACK impacted and changed their concept of pedagogy to heutagogy. The teachers used mobile applications to facilitate their students’ inquiry-based learning of English as a subject as well as a medium of digital literacy. In order to select mobile applications for their lesson, the teachers developed a modified version of quality criteria for mobile applications. This study suggests there should be well-developed quality criteria for evaluating affordances of mobile applications.

The purpose of this research is to investigate characteristics of science content knowledge and pedagogical content knowledge shown in the primary school science classes. Through analysis of classroom teaching, explore the features and differences between primary and secondary school science PCK. Using open-ended interviews with the teachers and group discussions on a regular basis to analyze and compare classes of five primary school teachers, the relationship between CK and PCK. Regardless of the school level the teacher's PCK and professionalism is required with varying focus and emphasis. The features of the primary school teacher's PCK are as follows: Firstly, elementary teach secondary teach content, teachers value pedagogical knowledge (PK) content knowledge (CK). The primary school PCK requires more of understanding of students and teaching methods that to subject areas. PCK be without content knowledge, and the teacher's PCK is subject-specific In addition to the characteristics of PCK in the primary school science teaching, ways to set up professional exchange or collaboration between primary and secondary teachers, and to provide supplementary in-service training focused on content knowledge for primary school teachers.

The purpose of this study is to find out how effective native content can be and how much 1) the web site type (news vs. entertainment vs. social networking site) and 2) the native content appeal (emotional vs. informational) will influence reader’s evaluations about a) the ad/website where the ad is placed and b) reader’s persuasion knowledge. The study also included an individual’s ad skepticism as one of the independent variables, arguing that the level of ad skepticism will influence the evaluations about the ad/website and individual’s persuasion knowledge. The result of the study can be helpful for advertisers to decide where and how to present native content. An online experiment, 3 (website type: news site/entertainment site/Facebook) X 2 (native content appeal: emotional/informational) X 2 (individual’s ad skepticism: high/low) was conducted to estimate the effects of independent variables on dependent variables, such as attitude towards the ad, website’s evaluation and individual’s persuasion knowledge. Introduction One of the newest ways of online advertising is ‘native ad’ or ‘native content.’ This new form of advertising provides companies the opportunity to introduce their products or services in a more natural way via online. Native ads normally match the design of other contents presented in the website and it should be perceived naturally as the rest of the content there (for example, in an online news site, the ad should be presented as news). Since native ads fit into the design of the site and people are there looking for stories to read, they provide higher rates of engagement as well as brand perception. However, there is a possibility of people feeling ‘deceived’ after realizing the story they click to read is no other but advertising. Furthermore, in the case of news websites, there have been instances of disapproval regarding native content. One of the arguments against native content presented in news sites points out that it is not ethical to present ads in the format of news. On the other hand, paid content can be seen as a useful alternative for non-intrusive online advertising which can generate more views among the users. Despite the increase of native content as a new form of advertising, academic study about native content (ads) is still difficult to find. The purpose of this study is to find out how effective native content can be and how much 1) the web site type (news vs. entertainment vs. social networking site) and 2) the native content appeal (emotional vs. informational) will influence reader’s evaluations about a) the ad/website where the ad is placed and b) reader’s persuasion knowledge. The study also included an individual’s ad skepticism as one of the independent variables, arguing that the level of ad skepticism will influence the evaluations about the ad/website and individual’s persuasion knowledge. Native content appears naturally, functioning like the rest of the content in the website. This characteristic makes it difficult for some people to tell the difference between the editorial content and paid content. By including ad skepticism as an independent variable, this study will show how people with high/low levels of ad skepticism will deal with this type of advertising. The result of the study can be helpful for advertisers to decide where and how to present native content. An online experiment, 3 (website type: news site/entertainment site/Facebook) X 2 (native content appeal: emotional/informational) X 2 (individual’s ad skepticism: high/low), was conducted to estimate the effects of independent variables on dependent variables, such as attitude towards the ad, website’s evaluation and individual’s persuasion knowledge. Literature Review Native Advertising and Evolution of Advertorials Native advertising is a method marketers use to present content in an interesting and subtle way on different websites or social media in a way that is almost camouflaging with the other content presented there. According to a IPG Media Lab survey, native advertising presented 53% more exposure than banners and it showed better performance regarding purchase intention, brand closeness and share intention. Native advertising’s origins can be found in what is defined as ‘advertorial’ (a combination of the words advertising and editorial). As we can find different arguments in native ads, we may also find discussions regarding similar topics related to advertorials. Cameron and Ju-Pak (2000)’s research supported that when stories are presented as editorial copy, they showed better credibility than those with a label of advertising. The ideas and main characteristics of advertorials appear today in native advertisements, bringing the advantages of advertorials to native ads. Marketers keep trying to make online advertising reliable and create effective sponsored content. However, as it was discussed with advertorials, when it appears difficult to tell the difference between news content and sponsored content, there is a possibility that the advertising is seen as deceptive (Pike, 2014). Since native content has become a popular online advertising format in reality, it is necessary to study it and the responses generated among the audience members of online news and different websites. Persuasion Knowledge Model & Ad Skepticism An individual’s ability to recognize and evaluate marketers’ persuasion goals and tactics is known as persuasion knowledge. Ad skepticism refers to a critical approach for consumers to evaluate and cope with advertising. Relating to the persuasion knowledge model and native content, one of the most important aspects for marketers is to determine the degree of persuasion knowledge that the target has in the different types of native content or the different website types where it is presented. This study will evaluate how an individual’s persuasion knowledge is affected after being exposed to native content. According to the persuasion knowledge model, we can assume that the more consumers know about the persuasion attempt of an agent, the lesser they are being persuaded. This study examined how the exposure to a new way of online advertising (native content) affects users’ persuasion knowledge. In the meantime, consumers with a higher level of skepticism make it harder for advertisers to find the effective format of online advertising. Consumers with a high level of skepticism may also be more aware of advertising strategies which leads to less positive responses to ads that use subtle persuasive techniques (Obermiller & Spangenberg, 1998, 2000). Previous research has shown that ad skepticism varies depending on advertising formats: banner advertisements present higher levels of skepticism than sponsored content. The present study differentiated persuasion knowledge from ad skepticism. Ad skepticism is regarded as a personal attribute. It is measured in order to find out how participants' level of ad skepticism (high/low) will influence the effects of native content. On the other hand, persuasion knowledge is seen as a way users will cope with advertising strategies. This research examined the effects different native advertising have on a reader’s persuasion knowledge. Research Questions & Hypotheses [RQ1]: Will the effect of native content on site evaluation be different depending on the website type, native content appeal and individual’s ad skepticism? [RQ2]: Will content appeal and website type influence the effects of native content on site evaluation (before/after)? [RQ3]: Will the effect of native content on persuasion knowledge be different depending on the website type, native content appeal and individual’s ad skepticism? [RQ4]: Will the effect of native content on attitude towards the ad (affective/cognitive/behavioral attitude and advertising credibility) differ depending on website type, native content appeal and individual’s ad skepticism? [H1]: Informational native content will show more positive cognitive attitude towards the ad than emotional content. [H2]: Emotional native content will show more positive affective attitude towards the ad than informational content. Research Method An online experiment was conducted in May 2016 in Seoul, Korea. Using a convenient and snowball sample, a total of 359 adult participants aged 18 or older took part in the online experiment. Experiment stimuli were created based on existing brands with high-involvement products (LG G5 mobile phone and CITI credit card). Experimental stimuli were created by the researchers to resemble native content and native ads in news sites, entertainment sites, and Facebook. The format of the contents was adapted from native content published in different sites (news site: /entertainment site: Huffington Post Korea, ). Participants were randomly assigned to one of the 6 cells (3 website types X 2 appeals). First, ad skepticism was measured followed by website evaluation. After each stimulus was shown, attitude towards the native ad, site evaluation and persuasion knowledge were measured. RESULTS AND DISCUSSION Despite the growing popularity of native advertising in various online sites, little research has been performed regarding its effects and possible variables influencing the effects of native advertising. This study intended to contribute to find an effective way to create native content and a suitable place to place the native content. The study found significant interaction effects between content appeal and site evaluation (before/after). Also, significant interaction effects on persuasion knowledge were found between website type and content appeal. On the other hand, main effects of independent variables (native content appeal and ad skepticism) showed interesting results. Results of RQ1 showed that a lower ad skepticism and informational content appeal presented more significant effects on site evaluation. In other words, participants with lower levels of ad skepticism were more likely to positively evaluate the site. Also, when comparing the types of appeal, informational native content turned out to be more effective on site evaluation than emotional appeal. However, the online experiment failed to detect a meaningful connection between website type and site evaluation. Significant differences were found in terms of participants’ website evaluation before and after presenting experimental stimuli, native content (RQ2). Contrary to what was expected, emotional appeal presented a bigger mean difference between site evaluation before and site evaluation after. This may be due to participants’ feeling of deception from native content with emotional appeal that leads a lower website evaluation among research participants (Howe & Teufel, 2014). According to Moore and Rodgers (2005), due to high levels of skepticism, online ads are perceived as the least reliable source of credibility. This can explain why content with informational appeal showed more favorable website evaluation over content with emotional appeal. The interaction effect between content appeal and website type on persuasion knowledge was significant. That is, informational appeal showed higher persuasion knowledge for both Facebook and news sites, whereas emotional appeal showed higher persuasion knowledge for entertainment sites. This result is consistent with the literature review presented above regarding website context and online advertising. Meanwhile, the fact that informational appeal increases persuasion knowledge on Facebook can be a subject for further research. Main effects of content appeal and ad skepticism were also found in increasing persuasion knowledge (RQ3). Ad skepticism showed significant main effects on attitude towards the ad over all four categories (affective, cognitive, behavioral attitudes and ad credibility). In other words, participants with lower ad skepticism showed more positive affective/cognitive/behavioral attitudes towards the native content and believed the ad was better. This finding supported previous research on ad skepticism where consumers with low levels of skepticism had more positive responses to advertising (Obermiller & Spangenberg; 1998, 2000). In conclusion, this study showed that participants with a lower level of ad skepticism show more positive reactions to native content than those who tend to be more skeptical about advertising in general. Also, informational appeal appeared to be more effective when compared to emotional content: informational appeal native ads resulted in more positive cognitive/behavioral attitudes towards the native ad and more ad credibility (RQ4).

This study aims to describe the pedagogical content knowledge (PCK) and teaching performance of junior secondary language teachers based on the tests administered during the teacher certification program, and identify the correlation between both variables. It involved 124 junior secondary school teachers, consisting of 70 Indonesian language teachers and 54 English language teachers, from various schools in West Java Province, Indonesia. To organize research procedures, this study adopted a descriptive method used to describe the characteristics of teachers who participated in the teacher participation program, their current pedagogical content knowledge and teaching performance based on the test results. Findings show that PCK has a strong correlation with teaching performance. However, other factors such as employment status, academic qualification, and age have significant effects on the mastery of those two main variables. A further study should be conducted to gauge more sound findings.

During the last three decades, earth science has been re-conceptualized as an interdisciplinary discipline entitled Earth System Science (ESS), which is based on knowledge of the physical earth system and human impact on the earth. While there is increasing effort to teach earth as a system in K-12 education, teachers' preparedness of to teach earth system is still in its infancy. This article focuses on reviewing the literature of teachers' knowledge of earth systems and of how teachers' knowledge of subject matter affects their teaching practice and pedagogical content knowledge (PCK). First, the study investigated a literature of PCK in general as well as in science teaching. Then this study duscuss what teachers' subject matter knowledge (SMK) is and what it means to be in teaching earth system science. Third, a literature of teachers' knowledge of earth system was reviewed. Finally, a number of suggestions and implications are made as to what teacher education program should do to better prepare future teachers to teach earth systems.

교과교육학지식(PCK)은 과학 교사의 전문성을 나타내는 지표로 인식되어 왔다. 이 연구에서는 예비 교사와 현직 교사의 주제-특정적 PCK를 비교 분석하였다. 이를 위해 과학 교사들의 PCK를 명시적으로 드러낼 수 있는 분석틀을 개발 및 적용하여 예비 및 현직 지구과학 교사를 대상으로 동일 주제에 대한 PCK 차이를 분석하였으며, 서로 다른 2개 주제에 대한 PCK가 어떻게 달라지는지를 각각 분석하였다. 연구 결과, 동일 주제에 대한 예비 교사와 현직 지구과학 교사의 PCK는 구성 요소에 따라 큰 차이가 있음을 알 수 있었다. 서로 다른 주제에 대한 PCK의 변화는 경향성을 나타내지는 않았으나, 구성 요소 및 교사에 따라 매우 큰 차이를 나타내었다. 이 연구를 통해 PCK의 주제-특정성을 확인하였으며, 과학 교사의 수업 전문성 개발 및 평가에 PCK분석틀 및 프로파일의 활용가능성에 대해 논의하였다.

본 연구의 목적은 교사의 과학 교과교육학 지식의 발달이 교수 실제와 교수 효능감에 어떤 영향을 미치는가를 알아보는데 있다. 연구 목적을 달성하기 위한 연구 문제는 첫째, 교사의 과학 교과교육학 지식의 발달과 과학 교수 효능감은 어떤 관련성이 있는가? 둘째, 교사의 과학 교과교육학 지식의 발달 정도에 따라서 과학 교수 실제에 어떤 영향을 미치는가? 셋째, 교사의 과학 교수 효능감 정도에 따라서 과학 교수 실제에 어떤 영향을 미치는가? 이다. 이를 해결하기 위해서 53개 공립 초등학교에서 120명의 교사를 표집하여 과학 교과교육학 지식 측정 도구와 과학 교수 효능감측정 도구를 투입하였고, 수업 관찰과 면담을 통하여 데이터를 획득하였다. 연구 결과는 다음과 같다. 첫째, 교사들의 과학 교과교육학 지식과 과학 교수 효능감은 경력이 많을수록 점차 증가하며, 학력이 높을수록 발달한다. 과학 교과교육학 지식과 과학 교수 효능감의 상관분석 결과 둘 사이에 높은 상관 관계가 있었으며 통계적으로도 유의미하였다. 둘째, 과학 교과교육학 지식이 높은 교사의 수업 실제의 특징은 교사가 가지고 있는 과학 교과교육학 지식을 충분히 활용하고 있었으며 수업 전체에 대한 자신감을 가지고 있었다. 셋째, 과학 교수 효능감이 높은 교사의 수업 실제의 수업의 초기에 수업 목표와 학습 문제를 학생들에게 정확하게 인식시키려고 노력하며 수업의 각 과정에도 재인식시키는 특징이 있다. 자기의 과학 수업에 대한 상당한 자신감이 있고 내용에 대한 지식뿐만 아니라 수업에 관련된 그 외의 분야에도 지식이 풍부한 공통점이 있다.

본 연구의 목적은 과학 교과교육학 지식의 본질과 역할이 무엇이며 어떻게 발달하는가를 알아보는데 있다. 구체적인 연구 문제는 첫째, 과학 교과교육학 지식의 본질과 구성 요소는 무엇인가? 둘째, 과학 교과교육학 지식의 가치와 교사의 과학 교과교육학 지식은 어떻게 발달하는가? 이다. 이를 해결하기 위해서 본 연구는 실증적이고 경험적인 데이터에 의한 문제해결보다는 문헌 연구를 통한 접근을 하였다. 연구 결과는 다음과 같다. 과학 교과교육학 지식의 본질은 첫째, 교사 개인이 특정한 과학 수업 상황 속에서 과학 교과를 가르치는데 사용하는 과학의 내용 지식과 과학 교수방법 지식의 합성체를 의미하는 것이다. 둘째, 교사 자신이 가지고 있는 교수를 위한 독특한 지식체로서 과학 교사 전문성의 요체가 되며, 자질 있는 과학 교사가 갖추어야 할 가장 핵심적이고 필수적인 사항이다. 셋째, 어떤 특수한 상황에서 특수한 내용을 어떻게 가르치느냐에 관한 지식으로서 이것은 각 교사마다 독특하게 구성된 지식 체계에 따라 달라진다. 과학 교과교육학 지식의 구성 요소는 과학 교수에 대한 지향, 과학 교육과정에 대한 지식과 신념, 특수한 과학 주제에 대한 학생들의 이해에 관한 지식과 신념, 과학에서 평가에 관한 지식과 신념, 과학 교수를 위한 수업전략에 관한지식과 신념이다. 과학 교과교육학 지식의 발달은 교과 내용에 대한 개념적 지식이 충분히 형성되어야 하며, 이 내용 지식을 실제적인 교수 경험을 통하여 반복적으로 사용함으로써 발달한다.

교육이론과 실행 간 격차는 오래전부터 논의되어 왔으나, 본 연구에서는 이론과 실행 간 관계속에서 이론의 역할에 대한 논의가 충분하지 않다고 판단하였다. 이에 이론의 영역을 과학교사의 내용 지식(SMK: Subject Matter Knowledge)과 교수내용지식(PCK: Pedagogical Content Knowledge)에 한정하여, 이와 관련된 기본 개념을 재구조화하고자 하였다. 이를 위해 문헌연구를 기반으로 연구문제와 관련된 내용을 정리하고, 가설적 제안과 가설 검증을 위해 필요한 실증적 연구도 함께 제안하였다. 첫째, 교과 내용 지식을 학생이 알아야 할 지식과 상위지식으로서 교사가 알아야 할 지식으로 나누고, 교사가 알아야 할 상위지식의 유형을 제시하면서, 이러한 상위지식이 교사의 수업 실행과 연결되기 위해서는 상위지식도 학생지도를 위해 직, 간접적으로 역할을 할 수 있어야 한다는 점을 강조하였다. 둘째, 심리학의 체화된 인지(embodied cognition) 이론에 기초하여, 교사의 지식이 상황에 맞추어 적절하게 변형되면서 즉각적으로 실행되려면 체화된 PCK (embodied PCK) 개념이 필요하다는 점을 제안하고, 체화된 PCK의 특징과 과학교사의 수업 실행에서 이것이 어떠한 역할을 하는지 논의하였다. 마지막으로 PCK와 체화된 PCK를 포함하여 이론 과 실행 간 관계를 강조하는 새로운 PCK 모델을 제안하고, 그 특징을 논의하였다. 본 연구에서 제시한 논의와 가설적 제안 및 실증적 연구의 제안은 이론과 실행 간 관계 속에서 이론의 역할과 기능에 대한 보다 깊은 이해에 도움을 줄 것으로 기대되며, 나아가 이론과 실행 간 조화를 위한 기반을 제공할 것으로 기대한다.

이 연구는 중･고등학교에서 근무하는 경력 10년 내외의 교사 48명을 대상으로 ‘모든’, ‘어떤’이 있는 명제에 대한 교수학적 내용 지식의 특징을 분석하는데 목적을 두었다. 이를 위해 관련 선행 연구를 검토하여 지필 검사 문항 개발의 주요 관점을 추출하고 이에 비추어 검사 문항을 개발하였다. 개발한 검사 문항을 활용하여 지필 검사를 실시한 다음, 검사 결과는 선행 연구 검토를 통해 구체화된 주요 이슈를 분석틀로 삼아 그 특징을 기술하였다. 이로부터 ‘모든’, ‘어떤’이 있는 명제에 대한 ‘교과 내용 지식’ 및 ‘학생의 이해에 대한 지식’의 두 가지 측면에서 교사들이 보인 교수학적 내용 지식의 특징을 6가지로 요약하였다. 이러한 교수학적 내용 지식의 특징은 명제 지도와 관련된 교사 교육 프로그램의 설계와 실행에 의미있는 시사를 줄 수 있다.

이 연구에서는 초․중등교사들의 TPACK 함양을 위한 전략을 마련하기 위하여 TPACK에 대한 교사들의 인지경로를 분석하고, TPACK 요소들 간의 구조적 관계를 밝혔다. 이를 위해 TPACK에 대한 교사들의 자기효능감을 측정할 수 있도록 기존의 측정도구를 번안하고, 평가관련 문항을 새롭게 추가하여 초 중등교사들을 대상으로 설문 조사를 실시하였다. 그런 다음, 설문 조사 결과를 바탕으로 탐색적 요인분석을 실시하였다. 분석 결과, 기존의 7개 요인 41개의 문항이 7개 요인 36개의 문항으로 재구성될 수 있었고, 확인적 요인분석을 통해 탐색된 TPACK 모델의 신뢰도와 수렴타당도, 판별타당도 등을 확보할 수 있었다. 또한 연구 가설에 기반하여 구조방정식모델을 구성할 수 있었는데, 이 모델을 통해 TPACK을 구성하는 요인들간의 인과 관계를 확인할 수 있었다. 예를 들어, 초 중등교사들의 경우, PK와 CK는 PCK에, TK와 PK는 TPK에, TK와 CK는 TCK에, PK, TPK, TCK는 TPACK에 각각 유의한 영향을 미치는 것으로 나타났으며, TK, CK, PCK는 TPACK에 유의한 영향을 미치지 않는 것으로 나타났다. 이와 같은 연구 결과는 교사들의 TPACK 함양을 위한 교사연수 프로그램이나 전략을 마련하기 위한 기초 정보를 제공해 줄 수 있을 것으로 기대된다.
