Abstract:

The unified learning model (ULM) focuses on students' engagement, motivation, prior knowledge, and working memory. This study employs the use of video games to assess students' learning through a 3D chemistry gaming environment. In this human-subjects research, students carried out missions and applied reasoning to solve problems appropriate for general chemistry content. For learning to occur, students must be engaged and motivated as stated in the ULM. Learning cannot necessarily be accomplished by experience alone, and critical thinking is required to turn the experience into learning. The

Abstract:

This study investigated possible alternative Chemistry teaching methods to improve the learning and thus the pass rate of the learners of access programmes at the Port Elizabeth Technikon. The study traced Chemistry learning from the Pre-Technician course to the present Science Foundation Certificate. Since the latter programme is a new course with new criteria, only implemented since the beginning of 2003, it provided a suitable platform for the evaluation and updating, if necessary, of new teaching methods. The study was limited to the subject of Chemistry. The participating learners in this

Abstract:

Stoichiometry is an important topic in chemistry. It tells how many reactants are required to produce a certain amount of product in terms of mass, mole and volume. Learning stoichiometric calculation involves the understanding of certain concepts such as the mole, stoichiometric ratios and chemical equations. Some studies attributed the failure in learning stoichiometry to the unfamiliarity with the amount of substance in a mole and students’ weakness in the mathematical ability. Nevertheless how students connect the submicro level and the symbolic level in learning stoichiometry was not disc

Abstract:

For the last fifteen years, research on students' conceptions of physical phenomena has been directing our attention to the value of knowing and considering children's prior ideas in science teaching. Although many who are concerned with science education are aware of and see wisdom in this perspective of teaching, there are many realities, including the content of the discipline, that pose great challenges in translating it into practice in science classes. Currently, in collaboration with teachers, science educators are actively conducting classroom studies. In this process, teachers as res

<p>This thesis reports an investigation of how acid-base models are taught and understood in Swedish upper secondary school. The definition of the concepts of acids and bases has evolved from a phenomenological level to an abstract (particle) level. Several models of acids and bases are introduced in Swedish secondary school. Among them an ancient model, the Arrhenius model and the Brønsted model. The aim of this study was to determine how teachers handle these models in their teaching. Further, to investigate Swedish upper secondary students’ ideas about the role of chemistry models, in gener

Abstract:

The quality of the teaching and learning of chemistry in Nigeria is of great concern to parents, teachers, and students and has been tied to various factors such as a lack of teaching resources, learning materials and well qualified teachers, large class sizes and poor funding. This resulted in poor student performance and lack of interest in chemistry. Also, learning chemistry concepts tends to be by rote and memorising of content, and as such, students do not perceive learning chemistry as relevant to their lives. These issues motivated the Researcher to explore how teaching and learning of

Abstract:

Many students currently entering college are able to solve mathematical problems but often do not understand the chemistry concepts underlying their calculations. High school chemistry teachers from Texas and the United States (US) were surveyed as to what topics they teach in their chemistry classes. A subset of Texas teachers was also interviewed about their instruction. The survey indicated that less-experienced Texas teachers are omitting a number of topics from their chemistry instruction, as compared to more experienced teachers. No differences were seen for those topics among US teacher
