Science for all: Boosting the science motivation of elementary school students with utility value intervention

Publication date: April 2019Source: Learning and Instruction, Volume 60Author(s): Da-Jung Diane Shin, Minhye Lee, Jung Eun Ha, Jin Hyun Park, Hyun Seon Ahn, Elena Son, Yoonkyung Chung, Mimi BongAbstractThe need for students to learn science, technology, engineering, and mathematics (STEM) has increased steadily, while student motivation in this area continues to fall behind. We investigated the effects of science utility value intervention in increasing the science motivation (i.e., interest in science, appreciation of the role of science in future careers, and intention to engage in science-related activities) of Korean 5th and 6th graders. The usefulness of science for attaining the personal and communal goals inherent to various non-STEM careers was emphasized and internalized through classroom activities including postcard writing. At the end of the semester, students in the experimental group (n = 219) perceived greater personal and communal utility in science than those from the control group (n = 197). This enhanced perception of science utility led to greater interest, a higher likelihood of cognitively connecting science to future careers, and the willingness to engage in scientific activities.

AbstractObjectiveTo analyze the impact of pelvic computed tomography (CT) technique optimization on estimated dose and subjective and objective image quality.Materials and methodsAn institutional review board (IRB)-approved retrospective records review was performed with waived informed consent. Five CT scanners (various manufacturers/models) were standardized to match the lowest dose profile on campus via subjective assessment of clinical images by experienced musculoskeletal radiologists. The lowest dose profile had previously been established through image assessment by experienced musculoskeletal radiologists after a d...

ConclusionsThis study demonstrates high inter-observer correlation of PTI on MRI and high test –retest reliability indicating unconscious quadriceps contraction does not change the index sufficiently. Knee flexion significantly alters PTI, increased patellotrochlear engagement with flexion increases the index. We propose use of the formula cPTI = PTI -1.3a to correct the index to 0 degr ee knee flexion in clinical practice.

This study retrospectively evaluated the added value of MRI over X-ray in guiding the extent of amputation in a cohort of patients with surgically treated, pathologically proven osteomyelitis.Materials and methodsA database search revealed 32 cases of pathology-proven diabetic forefoot osteomyelitis between 2006 and 2016, in which X-ray, MRI, and surgery occurred within 30  days. Data collection included extent of osteomyelitis reported on imaging and extent of subsequent amputation using a point system. Added value of MRI over X-ray in guiding surgical resection was stated if the X-ray was negative, MRI was positive,...

Conclusion3D-MR imaging can be used to accurately diagnose and quantify the typical osseous pathological condition in femoroacetabular impingement and has the potential to eliminate the need for 3D-CT imaging and its associated radiation exposure, and the cost for this predominantly young group of patients.

ConclusionsPlexiform fibrohistiocytic tumor often manifests as a plaque-like or infiltrative process, sometimes without a round or oval mass, most commonly in the subcutaneous tissues of the upper extremity or head and neck region. Residual tumor is often present after initial surgery, and  may be indistinguishable from postoperative changes.
