Student understanding regarding topics in upper-division courses, such as biochemistry, is not well represented in the literature. Herein we describe a study that investigated students’ reasoning about Michaelis–Menten enzyme kinetics and enzyme inhibition. Our qualitative study involved semistructured interviews with fourteen second-year students enrolled in an introductory biochemistry course. During the interviews students were provided an enzyme kinetics graph, which they were prompted to describe. Students were asked to look for patterns and trends in the data and interpret the graph to draw conclusions regarding the types of enzyme inhibition observed, providing the opportunity for the students to engage in the science practiceanalyzing and interpreting data. Findings indicate students were able to attend to the relevant parameters (VmaxandKm) in the graph and subsequently associate changes inVmaxandKmto different types of enzyme inhibitors. However, students expressed difficulty explaining why a specific type of inhibition caused the observed change in the kinetic parameters and there was confusion regarding the distinction between noncompetitive and uncompetitive inhibition. Based on our results, we suggest instruction on enzyme kinetics should emphasize qualitative descriptions of the particulate-level mechanisms related to competitive and noncompetitive inhibition, with less emphasis on discussions of uncompetitive and mixed inhibition in introductory biochemistry courses.

In response to the changes taking place in collaborative online learning environments, this chapter discusses how the simultaneous emergence of collaborative technologies and the learner-centered movement impacts the role of the online instructor. As part of this review, research related to online moderation and facilitation of learning is summarized.  It is suggested that online instructors need to facilitate student generation and sharing of information, while assuming the role of learning coach or mentor to provide needed leadership and guidance.  Finally, ten key benefits and implications of e-learning, as well as ten potential problems and solutions, are summarized to assist e-learning decision makers and instructors.  Among the benefits include the permanence of the online text, the availability of online mentors, and the fostering of student idea generation.  Some consistent online learning problems include learner confusion, lack of justification of student reasoning, and difficulties in grading online content.  Instructors are provided with guidelines on how to take advantage of the benefits while limiting or overcoming the problems.

Post Assessment

Fundamental quantum chemistry concepts—quantization of energy, electronic structure, and light–matter interaction—are essential for understanding chemistry and spectroscopy, an important tool for studying molecules. However, very few studies have investigated how students learn and understand these concepts or how their learning can be supported. Drawing on the capacity of writing to support learning of difficult concepts, we designed an intervention that targeted quantum concepts in the context of the use of spectroscopy for identifying chemical composition of the Orion Nebula. A quasi-experimental design with a pre-post assessment on a control and treatment group was used to identify the gains associated with completing the WTL activity. Results from a three-tiered assessment show that WTL students significantly improved in their explanations of the concept of spectroscopic transitions and their overall confidence in their understanding. Analysis of their writing, follow-up interviews, and feedback served to explain the changes observed on the pre-post assessment.

The Impact

The course materials students are expected to utilise in online instruction vary. Studies have shown that students tend to enjoy online courses with lecture videos more than those without, but few studies have measured the impact of lecture videos on student outcomes. Do lecture videos increase student understanding and retention, thus improving student outcomes? Students were provided with one or more study aids, video lecture, PowerPoint or instructor-created notes for learning about the role of the Electoral College in US presidential elections. We assessed student retention and understanding of the Electoral College with a quiz as an indicator of student outcomes. We found that the video lecture in combination with a PowerPoint was the most effective study aid.

Hemoglobin Saturation

Most students enter the physiology classroom with one or more fundamental misconceptions about respiratory physiology. This study examined the prevalence of four respiratory misconceptions and determined the role of case analysis in the remediation of one of them. A case study was used to help students learn about oxygen transport in the blood and a conceptual diagnostic test was used to assess student understanding of the relation between Po2 and hemoglobin saturation by probing for the corresponding (Sa/Po2) misconception. A 36% remediation of the Sa/Po2 misconception was found to be associated with case analysis. This repair was selective since the frequency of three other respiratory misconceptions was found to be unchanged after classroom instruction about respiratory physiology in lectures and laboratories. Remediation of the Sa/Po2 misconception before an instructor-led, in-class case review was superficial and temporary. Explanations provided by students who correctly answered the Sa/Po2 conceptual diagnostic test showed improved conceptual understanding following case analysis. These results suggest that a learning strategy where students actively confront their faulty notions about respiratory physiology is useful in helping them overcome their misconceptions.

Dewasa ini, pemahaman siswa terhadap hak asasi manusia mengalami penurunan terkait perilaku-perilaku siswa yang tidak baik yang akan merugikan orang lain dan diri siswa. Penelitian ini bertujuan untuk mengetahui bagaimana peran dan kendala guru PPKn dan masyarakat sekolah dalam meningkatkan pemahaman siswa terhadap hak asasi manusia di dalam lingkungan sekolah SMPN 1 Sanggar. Penelitian ini menggunakan penelitian kualitatif dengan pendekatan deskriptif.Subjek dan informasinya adalah guru PPKn, Kepala Sekolah, Guru BK, dan Siswa.Teknik pengambilan sampel menggunakan purposif sampling.Metode pengumpulan data yang digunanakan adalah metode observasi, wawancara, dan dokumentasi.Jenis data berupa data kualitatif. Sumber data yaitu data primer dan sekunder. Tehnik analisis data yang dipakai adalah reduksi data, penyajian data, dan verivikasi. Hasil penelitian ini dapat disimpulkan bahwa peran guru PPKn dan masyarakat sekolah dalam meningkatkan pemahaman siswa terhadap hak asasi manusia di dalam lingkungan sekolah sudah terlaksana dengan baik berdasarkan hasil observasi dan wawancara yang peneliti lakukan.Adapun penghambat yang dihadapi adalah karna siswa yang kurang fokus terhadap pembelajaran yang disampaikan, faktor pergaulan, lingkungan hidup, masih berperilaku kekanak-kanakan dan sangat nakal. Nowadays, understanding students against human rights decline related behavior-the behavior of students who are not good that will harm others and ourselves, students. This research aims to find out how roles and constraints of the PPKn teachers and school community in improving student understanding against human rights in the school environment SMP 1 Workshops. This research uses qualitative research with a descriptive approach. The subject and the information PPKn is a teacher, school principal, teacher and student, BK. sampling Techniques using purposive sampling. The data collection method used is the method of observation, interviews, and documentation. The type of data in the form of qualitative data. Data source i.e. primary and secondary data. Data analysis technique used is the reduction of the data, the presentation of data, and verify. The results of this research it can be concluded that the role of the teacher PPKn schools and communities in improving student understanding against human rights in the school environment is already done well based on the results of observation and interviewing the researchers did. As for the barrier, the face is because students who are less focus on learning that is delivered, by Association, environment factors, still behaves childishly and very naughty.
