Investigating The Impact Of Reflexive Practices On College Students In A Science Laboratory Course, Chandrani Mishra

Dissertations

Emphasis on professional practices to develop students’ professionalism is currently a major focus of higher education. Studies have shown the benefits of reflexive practices in classroom to facilitate the development of students’ professional attitude or identity in some fields. Reflexive practices involve students in self-reflection where he/she reflects on his/her own actions. Little investigation about the benefits of reflexive practices in the development of students’ scientific identity in a science class led to my investigation. Development of a scientific identity of students and their overall interest and motivation in science is deemed essential for retaining students in STEM fields.

Assessing Awareness, Interest, And Knowledge Of Fractal Geometry Among Secondary Mathematics Teachers In The United States And China, Suanrong Chen

Dissertations

Fractal geometry has gained great attention from mathematicians and scientists in the past three decades (Fraboni, & Moller, 2008). As a new geometry language and subject, fractal geometry has significant value in teaching and learning secondary mathematics. The present study focused on investigating the current state of mathematics teachers’ awareness, interest, and knowledge of fractal geometry in the U.S. and China, as well as the factors that influence them.

The instrument of the study included a survey and a test designed by the researcher and validated by five experts. The results of the study indicated that secondary math teachers in …

Signaling Instructional Video For Mathematics, Kimberly W. Milner

STEMPS Theses & Dissertations

Video provides an increasingly valuable medium for delivery of instruction in a growing number of content areas. Growth of online instructional applications has been prompted by expansion of the Internet and video streaming technology, adding to the need for design practices that produce more effective and efficient instructional videos. This study examined the use of signaling for multimedia to reduce cognitive overload and increase mental effort when learning mathematical concepts and procedures from instructional video. Signaling addresses the issue of directing the learner's attention by using visual or verbal cues that stress importance and organization (Mayer, 2009). Effectively signaled instructional …
