The Impact of Field Trips and Family Involvement on Mental Models of the Desert Environment.

This study examined the mental models of the desert environment held by fourth‐ and seventh‐grade students in the USA and whether those mental models could be affected by: (1) classroom field trips to a desert riparian preserve, and (2) interaction with family members at the same preserve. Results generally indicated that students in this study were resolute in their models and that field trips did not impact the types of models students adhered to. Twenty‐three seventh‐grade students who self‐selected to participate in a Family Science Club with their parents did demonstrate a shift in their mental models and developed significantly more sophisticated models over time. A critical implication of the study is that unless transformation of mental models of the environment is an explicit goal of instruction, simple exposure to the environment (even within the context of life science instruction) will not transform understandings of how organisms within an environment act and interact interdependently.

Effects of Transferring to STEM-Focused Charter and Magnet Schools on Student Achievement.

ABSTRACT There have been strong calls to action in recent years to promote both school choice and the learning of science, technology, engineering, and mathematics (STEM). This has led to the burgeoning development of STEM-focused schools. Nine STEM-focused charter and 2 STEM-focused magnet schools that serve elementary-aged students were examined to assess the achievement of students who transfer to these schools, as compared to students transferring to non-STEM schools, in the content areas of mathematics, language arts, and reading. The achievement of students transferring to STEM-focused elementary schools was also evaluated after 3 years at their new school and compared both to students’ own prior achievement at their old school and to achievement of students comprising comparison groups. Results generally indicated no effect of STEM-focused magnet schools, but did indicate some positive effects of STEM-focused charter schools.

How Engineering Standards Are Interpreted and Translated for Middle School.

In this exploratory study we examined the alignment of Next Generation Science Standards (NGSS) middle school engineering design standards with lesson ideas from middle school teachers, science education faculty, and engineering faculty (4–6 members per group). Respondents were prompted to provide plain language interpretations of two middle school Engineering Design performance expectations and to provide examples of how the performance expectations could be applied in middle school classrooms. Participants indicated the challenges and benefits of implementing these performance expectations and indicated personal experiences that helped them to interpret the performance expectations. Quality of lessons differed depending on the performance expectation being addressed. Generally, respondents were better able to generate ideas that addressed the paradigm of students ‘‘analyz[ing] data from tests to determine similarities and differences among several design solutions’’ than having students ‘‘define the criteria and constraints of a design problem.’’ A notable finding was the scarcity of quality engineering lesson ideas. The greatest proportion of lessons were categorized as Vague and/or Overly Broad. It appears that NGSS engineering design standards can too easily be decoded in an excessively expansive manner, thus resulting in indefinite ideas that are difficult to translate into classroom practice.

Science and mathematics Advanced Placement exams: Growth and achievement over time

ABSTRACT Rapid growth of Advanced Placement (AP) exams in the last 2 decades has been paralleled by national enthusiasm to promote availability and rigor of science, technology, engineering, and mathematics (STEM). Trends were examined in STEM AP to evaluate and compare growth and achievement. Analysis included individual STEM subjects and disaggregation by ethnicity. Analysis indicates growth in STEM AP was extraordinary but was slightly outmatched by non-AP subjects. Moreover, growth in STEM AP has been most pronounced among underrepresented minorities, even though their achievement has slightly declined. Interestingly, the proportion of students scoring at the lowest level grew steadily for all students from 1997 to 2010, yet this proportion was substantially less for Asian and White students compared to underrepresented minorities. Finally, it was found that achievement in most high-participation STEM subjects slightly decreased from 1998 to 2013, while achievement held steady or slightly increased in lower participation STEM AP subjects.
