The Effect of College Student Demographic Variables on Teacher Enmeshment

Interactions between students and faculty outside of class appear to be linked to greater achievement during and after college (Anaya & Cole, 2001; Hathaway, Nagda, & Gregerman, 2002). However, sometimes there can be blurred personal boundaries and a lack of autonomy in relationships or what has been labeled enmeshment. The purpose of the current pilot study was to investigate the effect of race/ethnicity, gender, year in college, and college major on faculty-student relationships and teacher enmeshment. Teacher enmeshment was measured with the Teacher Enmeshment subscale of the Separation-Individuation Test of Adolescence (SITA; Levine & Saintonge, 1993). A sample of 165 undergraduate and graduate students from education and psychology classes at a small, private liberal arts institution in the Northeast participated. No significant differences among the different demographic groups were found on the total teacher enmeshment score. However, significant differences were found among students with different majors, by gender, and by race on individual items. Implications of these findings and suggestions for future research are provided.

Undergraduate Engineering Students' Understanding of Heat, Temperature, and Radiation

Difficulty understanding heat and temperature concepts has been recognized in engineering education. Confusion has been shown to persist after instruction. The purpose of this study was to determine whether undergraduate engineering students’ knowledge of four heat transfer concept areas significantly changed with instruction and whether this varied by major and GPA. Two hundred twenty-eight undergraduate engineering students from six institutions were assessed prior to and after instruction. Results showed significant improvement in most concept areas but mean scores were below mastery. Previously documented misconceptions persisted after instruction. Significant differences were found by major and GPA. Suggestions for future research provided.

The Effect of Direct Instruction versus Discovery Learning on the Understanding of Science Lessons by Second Grade Students

This study examined the effectiveness of discovery learning and direct instruction in a diverse second grade classroom. An assessment test and transfer task were given to students to examine which method of instruction enabled the students to grasp the content of a science lesson to a greater extent. Results demonstrated that students in the direct instruction group scored higher on the assessment test and completed the transfer task at a faster pace; however, this was not statistically significant. Results also suggest that a mixture of instructional styles would serve to effectively disseminate information, as well as motivate students to learn.
