We use the Survey of Thermodynamic Processes and First and Second Laws-Long (STPFaSL-Long), a research-based survey instrument with 78 items at the level of introductory physics, to investigate introductory and advanced students' difficulties with entropy and the second law of thermodynamics. We present an analysis of data from 12 different…

General Chemistry I is known as a STEM (Science, Technology, Engineering, Mathematics) gatekeeper, often playing a role in determining students' STEM college pathways and their career prospects. However, there have been recent efforts to transform General Chemistry I from a gatekeeper course into a gateway course by implementing equity approaches.…

We propose developing a method to set key educational skills which students need to achieve for each class using a student self-assessment questionnaire in analytical approach. It is difficult to set key academic skills for class since there are little systematic methods to set them. The questionnaire survey with 25 educational skills was…

Despite the impact of genetics on daily life, biology undergraduates understand some key genetics concepts poorly. One concept requiring attention is dominance, which many students understand as a fixed property of an allele or trait and regularly conflate with frequency in a population or selective advantage. We present the Dominance Concept…

Reciprocal teaching, a method of teaching first language reading comprehension, is explained and three distinct applications of the method and materials in second language instruction are described. Reciprocal teaching is viewed as a three-level hierarchy of components and strategies, reflected in the organization of materials and activities. The…

A study investigated linguistic, rhetorical, and strategic variables of the writing processes and products of 3 groups of graduate and undergraduate students: 28 native English-speaking Americans; 28 Koreans studying in the United States; and 90 Korean students in Korea. The last two groups were learners of English as a Second Language (ESL). Data…

A Scottish study of foreign/second language instruction for vocational purposes focused on teaching methods, skill assessment methods, and teacher and student perceptions of the effectiveness of different instructional approaches. Nine case studies of second language programs (French, German, Japanese, and Spanish) were conducted. Programs…
