Many introductory astronomy courses include concepts related to basic stellar properties. In general, these are concepts that originate from the human perception of starlight. This observational aspect is not easy to incorporate in the classroom. We explore if these concepts could be developed using the built-in data in a planetarium software.…

In this paper, we demonstrate how machine learning could be used to quickly assess a student's multimodal representational thinking. Multimodal representational thinking is the complex construct that encodes how students form conceptual, perceptual, graphical, or mathematical symbols in their mind. The augmented reality (AR) technology is adopted…

Instructor Talk--the noncontent language used by an instructor during class time--is likely to influence learning environments in science classrooms from the student perspective. Despite Instructor Talk being found in every science course thus far, investigations into student perceptions and memories of it are limited. We investigated to what…

A survey of introductory soil science or equivalent (ISS[subscript e]) instructors and courses at 79 institutions differing in land-grant status (38 land-grant, 41 non-land-grant) and Carnegie category (48 doctoral, 16 masters, 10 baccalaureate, 2 associate, 3 respondents did not identify by Carnegie classification) was conducted to collect…

This research was aimed at profiling student's thinking skills in dealing with Higher-Order Thinking Skills (HOTS) questions based on Marzano taxonomy by referring to 13 indicators. This pre-experimental research employed pretest-posttest design. The indicators included were comparison, classification, deductive reasoning, inductive reasoning,…

In this study, we evaluate the impact of rehearsing teaching skills in a mixed-reality classroom simulator on graduate teaching assistants' (GTAs) instructional practices as well as undergraduate student learning outcomes. The simulator training is intended to provide GTAs opportunities to deliberately practice essential pedagogical skills that…

This study has two purposes: the first is to explore experienced science teachers' perspectives on inquiry teaching, and the second is to categorize these perspectives into patterns. Fifteen junior high school science teachers experienced at inquiry teaching were selected, and a semi-structured interview was conducted to collect the teachers'…

The purpose of this quasi-experimental study was to examine attitude and achievement among fifth grade students participating in inquiry and lecture-based forms of instruction through interactive television. Participants (N = 260) were drawn from registered users of NASA's Digital Learning Network[TM]. The first three levels of Bloom's Revised…

Many college science educators have moved away from the traditional lecture format and toward learner-centered classroom environments. Yet many of us struggle to cover large content loads, reverting at times to rote memorization. This paper suggests rote memorization simply does not work and students must be actively engaged to learn. (Contains 1…

There is a particular need for inquiry-based lessons in the early elementary grades, when students are starting to develop their analytical skills. In this article, the authors present a 2-tiered inquiry-based lesson plan for 1st and 2nd grades that has been successfully used by graduate teaching fellows involved in the National Science Foundation…

The 12th iteration of the International Conference on Educational Data Mining (EDM 2019) is organized under the auspices of the International Educational Data Mining Society in Montreal, Canada. The theme of this year's conference is EDM in Open-Ended Domains. As EDM has matured it has increasingly been applied to open-ended and ill-defined tasks…
