When researchers code behavior that is undetectable or falls outside of the validated ordinal scale, the resultant outcomes often suffer from informative missingness. Incorrect analysis of such data can lead to biased arguments around efficacy and effectiveness in the context of experimental and intervention research. Here, we detail a new…

Team teaching is an innovative method to engage the large group and make lectures more interesting. The aim of the study is to evaluate the impact of team teaching in first year biochemistry lecture classes. After obtaining ethical clearance, 150 first year medical undergraduate students participated in the study on a voluntary basis. Topic…

This study examined the use of data visualization to improve financial literacy in adults. Using financial knowledge questions as test items this study used an experimental approach. Poisson regression was conducted on responses from 1,797 participants to an online survey via SurveyMonkey. Approximately one-third of respondents were assigned to a…

This research aims to reveal the effectiveness of the use of Kofie GeBoL media in improving (1) vector representation ability and (2) critical thinking ability in physics instruction. It is a descriptive quantitative study with the quasi-experiment design. It was conducted in two stages: empirical try out and implementation of Kofie GeboL to see…

Following Richards's (2015) ideas of using movie clips, videos, and games as valuable technological tools for language learning, the present study was conducted to investigate the effectiveness of using novel extracts and computer game cutscenes based on the same story to develop the vocabulary knowledge of English as a foreign language (EFL)…

This study compared the multidimensional effects of written and oral vocabulary exercises on EFL learners' retention of single-word items (SWI) and multi-word items (MWI). Two teaching experiments (times) were conducted with 54 college students, who studied four themed-based texts, two at a time. A total of 60 unfamiliar vocabulary items, 30 in…

This study examined effects of the Polya's problem solving Technique (POPSOT) as observed by Shaibu (1987) in Atadoga (2010) and conventional problem-solving Technique (CONPSOT) on cognitive achievement of physics students. A pre-test post-test quasi experimental design used adopted for the study. The sample comprised of 102 senior secondary two…

Educational videos are increasingly used to let students prepare lesson material at home prior to in-class activities in flipped classrooms. The main challenge of this teaching strategy is to stimulate students to watch these videos attentively before going to class. This paper describes the use of questions that pop-up within relatively long…

A digital instructional game with embedded multimedia was believed not limited to allowing the learner to visualize chemistry concepts while playing but enable them to collect relevant information that connects the understanding of the other. The subject was described as a core science area with multiple macroscopic, submicroscopic, and symbolic…

One of the most interesting studies on the role of L1 and contrastive analysis in vocabulary teaching is by Laufer and Girsai (2008). However, due to some methodological issues, their research findings are open to criticism and controversy. The current study aimed to replicate the research with a more rigorous design to re-investigate the…

This paper presents results from a randomized experimental design replicated over four semesters that compared students' performance in understanding landform evolution processes as measured by the pretest to posttest score growth between two treatment methods: an online interactive simulation tool and a paper-based exercise. While both methods…

The purpose of this study was to determine if blended learning effects the academic growth of students. The study used NWEA MAP to determine if RIT scores of students in blended learning schools increased more than schools where blended learning was not a focus. In addition, the study examined the perceptions of students and teachers regarding the…

Many studies have demonstrated that testing students on to-be-learned materials can be an effective learning activity. However, past studies have also shown that some practice test formats are more effective than others. Open-ended recall or short answer practice tests may be effective because the questions prompt deeper processing as students…

English-as-a-foreign-language (EFL) textbooks and internet resources exhibit various formats and implementations of exercises on phrasal verbs. The experimental study reported here examines whether some of these might be more effective than others. EFL learners at a university in Japan were randomly assigned to 4 treatment groups. Two groups were…

Research in the field of second language acquisition indicates that exposure to subtitled movies as comprehensible input generally enhances the acquisition of vocabulary. This paper reports on an experimental study which seeks to explore the effects of using subtitled movies on the vocabulary acquisition of English for Specific Purposes (ESP)…
