悖论与融合:大学网络课堂教学的价值与反思
黑龙江教育·理论与实践2024.4一、引言随着网络科学技术的发展和远距离教学的实际需求,各种新教学技术应运而生,形成了科技与教学融合的产物———网络课堂。
国内学者从新技术介绍、应用、反思等方面展开研究,促进了该领域的发展,但关于网络课堂的接受者———学生主体的实证研究较少,学生在课堂中的态度、情感体验、学习状态和效果如何值得深入研究。
二、研究设计与资料分析文章采用焦点小组访谈的方式,采取目的性整群抽样的方法对某医学院校2020级大三学生的网络课堂学习(主要指同步网络课堂)态度进行研究。
该班有50名学生(男生13人,女生37人),有一学期以上的网络课程学习经历。
在学生返校经过1个月的传统教学后,研究团队将其分成6个焦点小组进行深入访谈(40分钟/组),每组1名主持人和1名记录员。
焦点团体主题为“网络课堂和传统课堂的态度”。
访谈提纲包括“你对2种课堂的整体态度、你认为网络课堂的优势和弊端有哪些、你认为传统课堂的优势和弊端有哪些、你在2种课堂中的学习效果如何、你对理想课堂的形式有哪些期待”。
每组访谈的资料结合录音转录稿和现场记录资料在48小时内完成整理。
对资料的分析采用定性资料分析常用的主题分析法。
①熟悉数据:通过反复阅读文本,熟悉文本内容和内涵,对文本形成整体印象。
②初步编码:对文本抽样等级较低的文本进行初步编码。
③寻找主题:对初步编码进行整理和归纳,放入不同的潜在主题之下,形成“子主题”。
④检查主题:审查“子主题”是否指向某个中心概念;文本中是否有足够多的资料支撑该主题;该主题与研究问题之间的关系如何。
⑤定义和命名关键主题:对每个主题进行详细分析并准确清晰地命名,以确保主题间的独立性和其与研究问题的相关性。

The circuit combines an active doubler with anoutput buffer amplifier that delivers constant power over a range of input powers. The circuit has excellent rejection of the fundamental and harmonic products and requires a single positive bias supply. This MMIC uses Mimix Broadband's 2 um GaAs HBT device model technology to ensure high reliability and uniformity. The chip has surface passivation to protect and provide a rugged part with backside via holes and gold metallization to allow either a conductive epoxy or eutectic solder die attach process. This device is well suited for Millimeter-wave Point-to-Point Radio, LMDS, SATCOM and VSAT applications.Active DoublerCompact, Low-Cost Design Octave Bandwidth Operation +16 dBm Output Power-35 dBc Fundamental Leakage +5.0V, 125mA Bias Supply100% On-Wafer RF, DC and Output Power Testing 100% Visual Inspection to MIL-STD-883Method 2010FeaturesElectrical Characteristics (Ambient T emperature T = 25 o C)ParameterInput Frequency Range (fin)Output Frequency Range (fout)Input Return Loss (S11)Output Return Loss (S22)Saturated Output Power (Psat)RF Input Power (RF Pin)Fundamental Leakage (fin)Third Harmonic Leakage (3xfin)Fourth Harmonic Leakage (4xfin)Bias Voltage (Vcc)Supply CurrentUnits GHz GHz dB dB dBm dBm dBc dBc dBc VDC mA Min.2.55.0----3.0-----Typ.---15TBD +16--35-30-20+5.0120Max.6.012.0---+3.0---+5.5140Absolute Maximum RatingsSupply Voltage (Vcc)Supply Current (Id)Input Power (RF Pin)Storage Temperature (Tstg)Operating Temperature (Ta)Junction Temperature (Tj)+6.0 VDC 200 mA +10.0 dBm -65 to +165 O C -55 to MTTF Table MTTF Table Chip Device Layout1(1) Junction temperature affects a device's MTTF.

For safety, observe the following procedures:Do not ingest.Do not alter the form of this product into a gas, powder, or liquid through burning, crushing, or chemical processing as these by-products are dangerous to the human body if inhaled, ingested, or swallowed.Observe government laws and company regulations when discarding this product. This product must be discarded in accordance with methods specified by applicable hazardous waste procedures.Life Support Policy - Mimix Broadband's products are not authorized for use as critical components in life support devices or systems without the express written approval of the President and General Counsel of MimixBroadband. As used herein: (1) Life support devices or systems are devices or systems which, (a) are intended for surgical implant into the body, or (b) support or sustain life, and whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in asignificant injury to the user. (2) A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.ESD - Gallium Arsenide (GaAs) devices are susceptible to electrostatic and mechanical damage. Die are supplied in antistatic containers, which should be opened in cleanroom conditions at an appropriately grounded anti-static workstation. Devices need careful handling using correctly designed collets, vacuum pickups or, with care,sharp tweezers.Die Attachment - GaAs Products from Mimix Broadband are 0.100 mm (0.004") thick and have vias through to the backside to enable grounding to the circuit. Microstrip substrates should be brought as close to the die as possible. The mounting surface should be clean and flat. If using conductive epoxy, recommended epoxies are Ablestick 84-1LMI or 84-1LMIT cured in a nitrogen atmosphere per manufacturer's cure schedule. Apply epoxy sparingly to avoid getting any on to the top surface of the die. An epoxy fillet should be visible around the total die periphery. If eutectic mounting is preferred, then a fluxless gold-tin (AuSn) preform, approximately 0.001thick, placed between the die and the attachment surface should be used. A die bonder that utilizes a heated collet and provides scrubbing action to ensure total wetting to prevent void formation in a nitrogen atmosphere is recommended. The gold-tin eutectic (80% Au 20% Sn) has a melting point of approximately 280 C (Note: GoldGermanium should be avoided). The work station temperature should be 310 C 10 C. Exposure to theseextreme temperatures should be kept to minimum. The collet should be heated, and the die pre-heated to avoidexcessive thermal shock. Avoidance of air bridges and force impact are critical during placement.Wire Bonding - Windows in the surface passivation above the bond pads are provided to allow wire bonding to the die's gold bond pads. The recommended wire bonding procedure uses 0.076 mm x 0.013 mm (0.003" x0.0005") 99.99% pure gold ribbon with 0.5-2% elongation to minimize RF port bond inductance. Gold 0.025 mm (0.001") diameter wedge or ball bonds are acceptable for DC Bias connections. Aluminum wire should beavoided. Thermo-compression bonding is recommended though thermosonic bonding may be used providing the ultrasonic content of the bond is minimized. Bond force, time and ultrasonics are all critical parameters.Bonds should be made from the bond pads on the die to the package or substrate. All bonds should be as short as possible.2+-X1002December 2005 - Rev 08-Dec-05。

If using conductive epoxy, recommended epoxies are Ablestick 84-1LMI or 84-1LMIT cured in a nitrogen atmosphere per manufacturer's cure schedule. Apply epoxy sparingly to avoid getting any on to the top surface of the die. An epoxy fillet should be visible around the total die periphery. If eutectic mounting is preferred, then a fluxless gold-tin (AuSn) preform, approximately 0.001thick, placed between the die and the attachment surface should be used. A die bonder that utilizes a heated collet and provides scrubbing action to ensure total wetting to prevent void formation in a nitrogen atmosphere is recommended. The gold-tin eutectic (80% Au 20% Sn) has a melting point of approximately 280 C (Note: GoldGermanium should be avoided). The work station temperature should be 310 C 10 C. Exposure to these extreme temperatures should be kept to minimum. The collet should be heated, and the die pre-heated to avoidexcessive thermal shock. Avoidance of air bridges and force impact are critical during placement.Wire Bonding - Windows in the surface passivation above the bond pads are provided to allow wire bonding to the die's gold bond pads. The recommended wire bonding procedure uses 0.076 mm x 0.013 mm (0.003" x0.0005") 99.99% pure gold ribbon with 0.5-2% elongation to minimize RF port bond inductance. Gold 0.025 mm (0.001") diameter wedge or ball bonds are acceptable for DC Bias connections. Aluminum wire should beavoided. Thermo-compression bonding is recommended though thermosonic bonding may be used providing the ultrasonic content of the bond is minimized. Bond force, time and ultrasonics are all critical parameters.Bonds should be made from the bond pads on the die to the package or substrate. All bonds should be as short as possible.2+-34.0-46.0 GHz GaAs MMIC Image Reject Mixer。
